Figure1
chest radiograph showing an enlarged heart (A); Thoracic
echocardiography and esophageal echocardiography indicated that the
right coronary sinus of the aorta expanded to the right ventricular
outflow tract, and the continuity was interrupted, aortic valve
prolapse. This image shows the aneurysm and its rupture into the right
ventricular outflow tract. Color Doppler (white arrow) shows turbulent
flow through rupture and regurgitation of the aortic valve (B, C);
Intraoperative esophageal ultrasound indicated that after repair, the
broken shunt of the sinus tumor disappeared, but moderate to severe
eccentric regurgitation occurred in the aortic valve (white arrow, D,
E). Exploration revealed that the left coronary lobe of the aortic valve
was thin, with rupture and perforation at the root, about 0.3cm in
diameter (white arrow, F). Pathological examination of aortic valve
showed hyperplasia of fibrous tissue of aortic valve, hyalinosis and
mucoid transformation (G, H). Special aortic valve regurgitation
mechanism: Rupture of Valsalva aneurysm, Perforation of the leaflet in
the bottom area of the LCC, prolapsed NCC and ventricular septal
defect(I). NCC, Noncoronary cusp; RCC, right coronary cusp; LCC, left
coronary cusp.
