Complexity assessment and technical aspect of coronary angiogram and percutaneous coronary intervention following transcatheter aortic valve implantation.

Background: Performing selective coronary angiogram (CA) and percutaneous coronary intervention (PCI) post transcatheter aortic valve implantation (TAVI) may be challenging with various success rates of coronary ostia engagement.

Methods: Among all patients who underwent CA and/or PCI after TAVI from our single center TAVI registry, ostia cannulation success was reported according to the quality of ostia engagement and artery opacification, and was classified as either selective, partially selective or non-selective but sufficient for diagnosis.

Results: Among the 424 consecutive TAVI procedures performed at the aforementioned institution, 20 (4.

Transcatheter aortic valve implantation in nonagenarians: effective and safe.

Background: The number of nonagenarians is rising dramatically. These patients often develop severe aortic stenosis for which transcatheter aortic valve implantation (TAVI) is an attractive option. The aim of this study was to analyze the outcome of TAVI performed in a cohort of nonagenarian patients.

Alcohol septal ablation for obstructive hypertrophic cardiomyopathy: the perfect septal branch may originate from an atypical location.

Due to anatomical variability in the distribution and size of septal perforator arteries, not all patients are ideal candidates for alcohol septal ablation. Myocardial contrast echocardiography is essential in selecting the appropriate septal branch. We report a case where the target septal artery did not originate from the left anterior descending artery, but from the first diagonal branch.

Impact of bifurcation lesions on angiographic characteristics and procedural success in primary percutaneous coronary intervention for ST-segment elevation myocardial infarction.

Background: Bifurcation lesions (BFLs) remain a challenging lesion subset, often associated with lower success rates than less complex lesions. There are few data regarding the impact of BFLs in the setting of ST-segment elevation myocardial infarction (STEMI).

Aims: To assess the impact of BFLs on angiographic characteristics and procedural success in primary percutaneous coronary interventions (PCIs).

Measurement of left ventricular ejection fraction by real time 3D echocardiography in patients with severe systolic dysfunction: comparison with radionuclide angiography.

Aim: Measurement of left ventricular ejection fraction (LVEF) using real time 3D echocardiography (3DE) has been performed in subjects with preserved or modestly reduced systolic function. Our aim was to evaluate this technique in the subset of patients with severe systolic dysfunction.

Methods And Results: Consecutive patients with LVEF less than 0.
