Assessed Predictors of PPMI
The following factors were assessed as possible predictors: age; sex (male), hypertension, diabetes mellitus, baseline heart rate, prior aortic valve procedure, prior history of percutaneous coronary intervention (PCI), AF, RBBB, LBBB, left anterior fascicular block (LAFB), atrioventricular block (AVB), baseline inter-ventricular conduction delay (IVCD), change in QRS duration, increased inter-ventricular septal dimension (IVSD), left ventricular outflow tract calcification for non-coronary, right and left coronary cusp, type of valve used SEV versus BEV, logistic EuroSCORE, post-procedural AVB, valve size/annulus size, depth of implant into the ventricle, and pre- and post TAVR balloon dilatation.
Certain factors assessed as predictors that were isolated from individual studies were not included: obesity, chronic obstructive pulmonary disease (COPD), mitral regurgitation, previous myocardial infarction, vascular disease, use of home oxygen, amiodarone, B-Blockers, presence of severe aortic stenosis, bicuspid and tricuspid aortic valve, pre-intervention bifascicular block, access route (transapical vs transfemoral vs transaortic), increase in balloon size and operative time.
