REDUCTION IN RADIATION AND CONTRAST DOSE IN TRANSCATHETER AORTIC VALVE REPLACEMENT OVER TIME: A SINGLE-CENTER EXPERIENCE

Transcatheter aortic valve replacement (TAVR) is recommended for severe aortic valve stenosis (AS). This study aims to evaluate the association between radiation dose, time and contrast dose in TAVR with improved experience over time. A Retrospective analysis of 570 patients with severe AS who

FEASIBILITY AND SAFETY OF USING A 29 MM EDWARDS SAPIEN 3 VALVE FOR TAVR IN PATIENTS WITH ANNULAR AREA LARGER THAN 683MM2

The Edwards Sapien 3 (S3) 29 mm valve has been used for transcatheter aortic valve replacement (TAVR) with good results in patients with Aortic annular areas up to 683 mm2. TAVR is not usually performed on patients with larger than FDA recommended annular areas of 540-683 mm2. These FDA

CRT-700.26 The Impact of Gradient and Flow on the Outcomes of TAVR in Severe Aortic Stenosis with Preserved Left Ventricular Ejection Fraction

While transaortic flow and gradient are important determinant of prognosis in patients with severe aortic stenosis treated medically or with surgical aortic valve replacement, it is unclear whether these echocardiographic values are still predictive of outcomes in patients with severe aortic

Successful Coronary Protection during TAVI in Heavily Calcified Aortic Leaflets in Patient with Short and Low Left Coronary System

Transcatheter aortic valve replacement has been recently approved for patients who are high or intermediate risk for surgical aortic valve replacement. The procedure is associated with several known complications including coronary related complications. Coronary obstruction is rare but disastrous complication, and it is associated with a high mortality rate. Coronary protection technique has emerged as a preemptive technique to avoid this complication. We present a case of successful coronary protection during TAVR in severely calcified left cusp in patient with short and low left ostium.

Severe aortic stenosis in dextrocardia with situs invertus and anomalous single coronary ostium treated with transcatheter aortic valve replacement

Dextrocardia with situs inversus presents a unique anatomy with right-sided vascular system that may be associated with a number of additional cardiac and vascular malformations. A rare association is the presence of a single coronary artery ostium. To our knowledge, this is the first reported case of transcatheter aortic valve replacement using Edwards SAPIEN S3 valve in Dextrocardia patient with single coronary artery take off.

BALLOON POST-DILATION OUTCOMES FOLLOWING TRANSCATHETER AORTIC VALVE REPLACEMENT AT A SINGLE COMMUNITY CARDIOVASCULAR CENTER

Paravalvular leak is a significant clinical predictor of mortality after transcatheter aortic valve replacement (TAVR). Intra-operative balloon post-dilation remains the most commonly used method to reduce paravalvular leak. However, no studies have compared outcomes of those patients who required
