Impact of left ventricular filling parameters on outcome of patients undergoing trans-catheter aortic valve replacement.

Aim: To assess the impact of left ventricular (LV) filling parameters on outcomes following trans-catheter aortic valve replacement (TAVR).

Methods And Results: A total of 526 TAVR patients were compared with 300 patients with severe aortic stenosis (AS) treated conservatively. Clinical variables were collected along with echocardiographic data at baseline, 1 month, and 6 months after study entry.

Hemodynamic performance and outcome of percutaneous versus surgical stentless bioprostheses for aortic stenosis with anticipated patient-prosthesis mismatch.

Objectives: We aimed to compare the performance and midterm survival of transcutaneous aortic valve replacement (TAVR) and surgically implanted stentless aortic valve replacement (SAVR) for severe aortic stenosis in patients anticipated to have patient-prosthesis mismatch (PPM).

Methods: A retrospective analysis was performed of 86 and 49 consecutive TAVR and SAVR patients with severe aortic stenosis and calculated minimal effective orifice area larger than the best projected effective orifice area. Cox hazard analyses were used to assess the effect of TAVR versus SAVR on outcome.
