Objectives. We sought to evaluate the ability of left atrial strain and derived index to discriminate patients with HFpEF from individuals with risk factors of HFpEF. Methods and results. A total of n=389 patients with risk factors for HFpEF finally was prospectively enrolled into the study, 51 of them were diagnosed with HFpEF by ESC diagnostic criteria. 55 patients were undergone left ventricular catheterization, 35 of them with LVEDP elevated. Left atrial strain was measured in all patients. Compared patients without HFpEF, LASr and LASr/(E/e’) was lower in HFpEF; E/LASr, LAVi/LASr and LVMI/LASrwas higher in patients with HFpEF. After adjusted for hypertension, diabetes, chronic kidney disease, LVEF and NT-proBNP, multivariate logistic regression analyses showed that LASr and derived indexes(E/LASr, LASr/(E/e’), LAVi/LASr and LVMI/LASr) were still the predictors of HFpEF in their respective models. LASr had good diagnostic accuracy for HFpEF. Of the left atrial strain derived parameters, LVMI/LASr was the best discriminatory ability for HFpEF (AUC 0.796, cutoff value 5.2, specificity 82%, sensitivity 73%). LASr, LASr/(E/e’), LAVi/LASr and LVMI/LASr with higher AUC was superior to conventional echocardiographic measures of diagnosing HFpEF. LASr and derived indexes were incorporated into the ESC diagnostic criteria, LASr-HFA-PEF score system (AUC=0.804) had a higher detection rate of LVEDP≥16mmHg than the HFA-PEF score system (AUC=0.781). Conclusion. LASr and derived indexes with good accuracy beyond conventional echocardiographic parameters discriminate HFpEF from patients with risk factors of HFpEF. LASr and derived indexes incorporated into the ESC diagnostic criteria will improve the diagnostic efficiency.

Background: Right ventricular-pulmonary artery coupling (RVPAC) is a predictor of outcome in pulmonary hypertension. However, the role of this parameter in dilated cardiomyopathy (DCM) remains to be established. The aim of this study was to assess the contribution of RVPAC to the occurrence of severe heart failure (HF) symptoms in patients with DCM using three-dimensional (3D) echocardiography. Methods: We prospectively screened 139 outpatients with DCM, 105 of whom were enrolled and underwent 3D echocardiographic assessment. RVPAC was estimated non-invasively as the 3D right ventricular stroke volume (SV) to end-systolic volume (ESV) ratio. Severe HF symptoms were defined by New York Heart Association (NYHA) class III or IV. We evaluated differences in RVPAC across NYHA classes and the ability of RVPAC to predict severe symptoms. Results: Mean left ventricular (LV) ejection fraction was 28±7%. Mean RVPAC was 0.77±0.30 and it was significantly more impaired with increasing symptom severity (p=0.001). RVPAC was the only independent correlate of severe HF symptoms, after adjusting for age, diuretic use, LV systolic function, LV diastolic function and pulmonary artery systolic pressure (OR 0.035 [95% CI, 0.004 – 0.312], p=0.003). By receiver-operating characteristic analysis, the RVPAC cut-off value for predicting severely symptomatic status was 0.54 (area under the curve=0.712, p<0.001). Conclusion: 3D echocardiographic SV/ESV ratio is an independent correlate of severe HF symptoms in patients with DCM. 3D RVPAC might prove to be a useful risk stratification tool for these patients, should it be further validated in larger studies.

Objective: According to Bernoulli Equation, systolic pulmonary artery pressure is obtained echocardiographically by adding estimated right atrial pressure (RAP) to the multiply of square of tricuspid regurgitation flow rate by four. RAP is estimated based on inferior vena cava (IVC) diameter and collapse. Our objective is to investigate usability of coronary sinus(CS) diameter and collapse, measured by echocardiography for estimating RAP. Methods: Our study is a single center, prospective study. 136 patients, over 18 years of age and without exclusion criteria, who admitted to Akdeniz University Hospital Cardiology Department between March 2017 and March 2018 and were scheduled to undergo right heart catheterization for any reason were included study. Results: Patients were divided into two groups as invasively measured RAP ≥10 mmHg (n: 57) and RAP <10 mmHg (n: 79). In group with RAP ≥10 mmHg, maximum IVC and CS diameter were higher than group with RAP <10 mmHg, IVC and CS collapse indices were lower (p <0.001). Optimal cut-off value for maximum IVC diameter was 19.6 mm (sensitivity 63.2%, specificity 87.3%), for IVC collapse index was 46.1 (sensitivity 75%, specificity 79.7%), for maximum CS diameter was 11 mm (sensitivity 64.9%, specificity 77%), for CS collapse index was 39.2 (sensitivity 75.4%, specificity 88.6%). Conclusion: Significant relationship was found between invasively measured RAP and maximum IVC diameter, collapse index and maximum CS diameter and collapse index. Results of CS parameters were as significant as results of IVC parameters therefore it shows that CS can also be used for estimating RAP.

Background: The left ventricle (LV) journey in their transition from hypertrophy to heart failure is marked by many subcellular events partially understood yet. The moment in which the structural abnormalities reach the umbral to induce myocardial dysfunction remains elusive. Aims: To evaluate the anatomic-functional relationship between LV wall thickness and longitudinal systolic dysfunction. Material and Methods: We prospectively performed clinical history and transthoracic echocardiogram on healthy individuals and patients with hypertension, left ventricle ejection fraction (LVEF) ≥50%, and absence of heart failure symptoms. Results: A total of 226 patients and 101 healthy individuals were recruited. The distribution for sex was similar between groups. The mean age was 67±13 years old in the patients, and 44% had concentric LV hypertrophy. LVEF was identical in both groups (63±6%); in contrast, global longitudinal strain (GLS) (-18.8±2.5% vs. -20.4±2%) and mitral annulus plane systolic excursion (MAPSE) (13.8±2.8 vs. 15.5±2mm) were lower. ROC curve classified optimally decreased GLS with LV septum thickness ≥13mm and decreased MAPSE with thickness ≥14mm. Multivariable logistic regression found that LV septum thickness is the only variable associated with longitudinal systolic dysfunction (OR= 1.1, CI95%= 1.05 – 1.15, p= 0.001, R squared= 0.38). Discussion: A progressive increase in LV wall thickness due to myocyte hypertrophy and interstitial expansion is associated with LV systolic longitudinal dysfunction. Conclusions: Patients with moderate or severe ventricular hypertrophy (septum ≥13mm) had longitudinal systolic dysfunction, GLS decreases with minor structural change than MAPSE, and LVEF is insensitive in detecting longitudinal myocardial dysfunction in patients with hypertension.

An 86-year-old man with end-stage renal disease on hemodialysis with an arteriovenous fistula in his left upper extremity presented to his hemodialysis session with thrombosis of his arteriovenous fistula. The patient underwent surgical thrombectomy. The patient later showed evidence of peripheral embolization and livedo reticularis. Transthoracic and transesophageal echocardiograms revealed a large thrombus (5x2 cm) in the left atrium prolapsing to the right atrium via a patent foramen ovale and another thrombus (white arrow) adherent to the apical wall of the right ventricle. The thrombus in the left atrium was intermittently crossing the mitral valve and entering the left ventricle.

Abstract A mediastinal carcinoid is a low-grade malignant tumor, which has low risk of metastasis, and cardiac metastasis is even rarer. When a patient has cardiac metastasis, the primary carcinoid is usually widely metastasized. In this case report, we presented occurrence of isolated left-sided cardiac metastases ten years after surgical removal of left anterior superior mediastinal carcinoid.

In this report, we present a rare case of severe mitral regurgitation due to isolated mitral valve chordal rupture without valve leaflet prolapse in a patient with Fabry cardiomyopathy. This finding could be due to subvalvular apparatus storage of glycosphingolipids rather than fibro-elastic deficiency, underlying how close cardiological follow-up of Fabry patients must be comprehensive and not only focused on left ventricular hypertrophy and arrhythmias. We feel that our finding could be of interest for the readership of your Journal.

Transthoracic and transesophageal imaging of the 30-year-old patient who presented with palpitations and shortness of breath revealed flow from the aorta to the right atrium. Aortic-right atrial fistula, which is a rare anomaly, was evaluated. It was considered congenital, as there was no acquired cause. Since the patient was symptomatic, it was closed percutaneously with the Amplatzer Duct Occluder II device.

Echocardiography is commonly utilized in patients with acute respiratory distress syndrome (ARDS) for assessment of cardiac function, volume status, and the potential development of acute cor pulmonale. In severe ARDS, prone positioning is frequently used, which imposes technical challenges during transthoracic echocardiography (TTE) image acquisition. Moreover, prone positioning can affect cardiopulmonary function in ways that are reflected on the echocardiographic findings in this position. Historically, a transesophageal approach was recommended when a patient is prone, with few studies reporting utility of TTE in this setting. However, recent publications have begun to address this knowledge gap. This review explores recent literature addressing the use of TTE in prone patients with ARDS, with a special focus on the cardiopulmonary effects of proning and potential solutions to the technical difficulties that arise in this position.

Background: Early cardiovascular impairment in obstructive sleep apnea (OSA) patients is often overlooked, leading to irreversible outcome. Left ventricular (LV) global longitudinal strain (GLS) derived from automated function imaging (AFI) echocardiography provides a fast tool to assess global longitudinal function. We therefore aimed to compare the feasibility and reproducibility of AFI with mitral annulus plane systolic excursion (MAPSE) as obesity is common in OSA. Methods: A comprehensive echocardiographic examination was done in 186 consecutive patients having polysomnography for suspected OSA in this prospective study. MAPSE was measured by using M-mode. AFI was derived by offline analysis of three long-axis views that semi-automatically detects LV endocardial boundary, which is adjusted manually as necessary. Variability of AFI and MAPSE were compared among the different subgroups and further tested in BMI subgroups. Results: Despite a relatively high obesity rate (42.9%), AFI was feasible in 94% (175/186) patients and MAPSE could be recorded in all patients. Although more segments were measured with AFI it showed excellent correlation (r=0.882) superior to MAPSE (r=0.819) between the expert and beginner. Intra- and inter- observer variability of AFI were comparable with MAPSE in Bland-Altman analysis, 5.5% and 6.5% for AFI, 6.2% and 8.8% for MAPSE, respectively. In repeated measurements, AFI showed higher intra-class correlation (ICC=0.95) than MAPSE (ICC=0.87). Furthermore, analysis showed that AFI was feasible even in more obese patients (BMI≥28kg/m2). Conclusions: Even in obese patients with OSA, AFI-GLS is feasible and more reliable for less expert operators than MAPSE for detecting LV longitudinal dysfunction.

Background: Because transcatheter closure of patent foramen ovale (PFO) has become effective for preventing cryptogenic stroke (CS), it is necessary to determine high-risk PFO associated with CS. This study aimed to clarify the importance of direct right-to-left (RL) shunt through the PFO for identifying high-risk PFO. Methods: We analyzed 137 patients with and without CS who were confirmed to have PFO. The timing of RL shunt through the PFO was evaluated by cardiac cycles after right atrium (RA) opacification on saline contrast transesophageal echocardiography. Direct RL shunt was defined as microbubbles crossing the PFO before and at the same time of RA opacification. Results: Cardiac cycles of microbubbles crossing the PFO were shorter in patients with CS than in those without CS (2.0 ± 2.2 vs. 0.5 ± 1.1, P < .01). Direct RL shunt was more frequently observed in patients with CS than in those without CS (77% vs. 29%, P < .01), with a sensitivity of 79% and a specificity of 71% for the association with CS. Multivariate analysis revealed that direct RL shunt was related to atrial septal aneurysm and low-angle PFO. Regarding functional features of PFO, the detection rate of CS was 50% for large RL shunt alone, and was increased to 83% when direct RL shunt was added. Conclusion: Direct RL shunt was associated with CS and had the incremental value in detecting PFO associated with CS for large RL shunt. The timing of RL shunt can be valuable for identifying high-risk PFO.

Background: Myocarditis have variable clinical presentation, evolution and prognosis. Aim of our study was to evaluate the value of speckle tracking echocardiography and cardiac magnetic resonance (CMR) in the prediction of ventricular arrhythmias and other cardiovascular adverse events in patients with acute myocarditis, at hospital admission. Methods: 70 patients (62 M, 8 F; mean age 31,3±13,2) with myocarditis and preserved left ventricle ejection fraction (LVEF) were enrolled. Electrocardiogram (ECG), continuous ECG monitoring, echocardiography with measurement of global longitudinal strain of the left ventricle (GLS), mechanical dispersion (MD) and CMR with quantitative measurement of delayed enhancement (DE) were performed. Adverse events were assessed (arrhythmias, heart failure, cardiogenic shock, syncope) during in-hospital stay. Results: We found a significant greater amount of DE mass in patients with cardiac arrhythmias (p = 0,01), but not of edema (p = 0,57). GLS was significantly impaired in patients with ventricular arrhythmias (p = 0,04), conversely MD was not significantly prolonged in this setting (p = 0,16). GLS > - 19.2% (sens 100%, specif 55,7%) and a DE mass >9,9 gr (sens 100%; specif. 58,6%) had the best sensitivity and specificity to identify patients with cardiac arrhythmias. Compared to GLS, DE mass showed a stronger association with ventricular arrhythmias (p < 0,001). Conclusions: in our study DE mass and GLS were associated with ventricular arrhythmias in patients with acute myocarditis and preserved LVEF. DE showed the stronger association with the occurrence of ventricular arrhythmias.

Spontaneous pseudoaneurysm of the aortic arch is an exceptionally rare and potentially life-threatening condition.Diagnosis of pseudoaneurysms of the aortic arch mainly depends on imaging examinations.Contrast-enhanced echocardiography, as a non-invasive, bed-side and radiation-free tool, plays an important role in the rapid diagnosis and postoperative follow-up of pseudoaneurysms of the aortic arch.

Rheumatic heart disease is the most common cause of mitral valve stenosis. Left atrial appendage thrombus is associated with mitral stenosis, but in rare cases the thrombus can extend to the left atrial cavity. We present a case of a severe rheumatic mitral stenosis and associated large left atrial thrombus, with embolic sequelae.

Double Inlet Left Ventricle through a common AV valve is a rare type of functionally univentricular heart. We report a fetus with double inlet left ventricle with discordant ventriculo-arterial connection and pulmonary atresia. The anatomy was readily apparent on three dimensional rendering by spatio-temporal imaging correlation technique(STIC)

Background: Concern exists regarding adequacy of visualization of stress echocardiograms performed without intravenous contrast in persons with Class III obesity (body mass index ≥ 40 kg/m2). Methods: Dobutamine stress echocardiography (DSE) was performed on 128 candidates for bariatric surgery with class III obesity without chest pain or pre-existent coronary artery disease (CAD). DSE without intravenous contrast was initially performed on 62 patients with class III obesity, then was subsequently was performed with intravenous contrast on 66 patients with class III obesity. Left ventricular (LV) regional wall motion was assessed at baseline and peak stress using the 16-segment model. Results: In the intravenous contrast group 1046 of 1056 LV segments studied (99.1%) were well-visualized and interpretable at baseline and 1044 of 1056 LV segments studied (98.9%) were well-visualized and interpretable at peak stress. In the non-contrast group 905 of 992 segments studied (91.2%) were well-visualized and interpretable at baseline and 886 of 992 segments studied (89.3%) were well-visualized and interpretable at peak stress. A significantly greater number of LV segments were well-visualized and interpretable in the intravenous contrast group than in the group compared to the non-contrast group, at baseline and at peak stress (p < 0.00001 for both). DSE was positive for ischemia in 1 patient. All patients underwent bariatric surgery without cardiovascular complications. Six months after surgery, all patients were alive; none developed cardiovascular events. Conclusion: The use of intravenous contrast during DSE significantly improves visualization and interpretability of LV segments in patients with class III obesity.

Objectives: Systolic and diastolic dysfunctions are related to adverse clinical outcomes in patients with sinus rhythm. The aim of this study was to clarify the prognostic significance of systolic and diastolic dysfunctions in patients with chronic persistent atrial fibrillation (AF). Methods: We evaluated data for 114 consecutive patients with chronic AF who underwent measurement of LVEDP at our hospital between 1 March 2011 and 31 December 2014. In total, 114 consecutive patients with chronic AF were divided into two groups according to the left ventricular ejection fraction (LVEF): LVEF < 50 (reduced ejection fraction, REF group) and LVEF ≥50 (preserved EF, PEF group). The PEF group was further divided into two subgroups according to the left ventricular end-diastolic filling pressure (LVEDP): LVEDP >15 mmHg and LVEDP ≤ 15 mmHg. The 3-year clinical outcomes were compared between the PEF and REF groups and the LVEDP ≥15 mmHg and LVEDP <15 mmHg groups. Results: During the 3-year follow-up period, the rate of heart failure (HF) hospitalisation and incidence of AF with rapid ventricular rhythm (RVR) were higher in the REF group than in the PEF group. Multivariate analysis revealed that REF was the only significant predictor of HF hospitalisation (hazard ratio, 4.71; 95% confidence interval, 1.48–15.02; p=0.009). Conclusions: Our observations during a mid-term follow-up period revealed that systolic dysfunction could be an important predictor of HF hospitalisation in patients with AF. However, elevated LVEDP may not be associated with mid-term adverse clinical outcomes in patients without systolic dysfunction.

Primary cardiac tumors are extremely rare.Most primary tumors are benign,and malignant tumors comprise about 15%1.Angiosarcoma is the most common type of primary cardiac malignant tumors.Compared with the left atrium or ventricle,the tumor prefer to occur in the right atrium or ventricle,especially the right atrium.In this case report,we present the case of a 32-year-old female with cardiac angiosarcoma primary to the right atrial appendage(RAA).
