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.
