CT imaging is the main imaging modality for procedure planning for TAVR. There are different planning tools available to determine the optimal angiographic view for valve implantation. In this study, we compare a novel direct 3D quantitative method b

Objective: To determine the safety and efficacy of dual-axis rotational coronary angiography (DARCA) by directly comparing it to standard coronary angiography (SA). Background: Standard coronary angiography (SA) requires numerous fixed static images

Background Visualization of coronary stents is increasingly challenging due to the reduction in stent strut thickness to improve deliverability. On the other hand stent expansion and precise implantation in the target vessel are important in optimizi

BACKGROUND The unique physical forces exerted on the femoropopliteal (FP) artery during movement have been implicated in the high rates of restenosis and stent fracture in this artery. Conformational changes in the FP artery during movement are impor

Current expert-recommended views for coronary angiography are based on heuristic experience and have not been scientifically studied. We sought to identify optimal viewing regions for first and second order vessel segments of the coronary arteries th

A 60-year-old woman with increasing dyspnea was found to have a para-prosthetic aorto-right ventricular fistula during post-operative evaluation. Due to her multiple sternotomies, she was considered to be high risk for open surgical repair and referr

Stent thrombosis (ST) in the era of bare metal stents (BMS) using high-pressure stent deployment and combined anti-platelet therapy is an uncommon but feared complication. There is concern for an elevated risk of stent thrombosis (ST) with drug-eluti
