Within 30 days after the procedure, 2 patients died; 1 from stroke and 1 from cardiac failure (30-day mortality: 7.4%). However, the bioprosthetic leaflets are mounted in the constraint mid-portion, which is located above the native aortic annulus; therefore, the … Choose Evolut™ TAVI for a larger Effective Orifice Area (EOA) — allowing patients to maintain a higher exercise capacity.5,6, For each increase of 1 mm Hg in mean gradient, the relative risk of heart failure recurrence† or heart failure-related death is increased by 6%.9, CoreValveTM Pivotal High Risk at 1 year13. 1-Year Outcomes With The Evolut PRO Self-Expanding Repositionable Transcatheter Aortic Valve With Pericardial Wrap. J Thorac Dis. Calculate your patients risk of prosthesis mismatch, Patient Prosthesis Mismatch (PPM) occurs when the effective orifice area (EOA) of a normally functioning prosthesis is too small in relation to the patient’s body size.3, A large Effective Orifice Area (EOA) reduces the likelihood of Patient Prosthesis Mismatch (PPM).

Background: On the basis of the definitions of the Valvular Academic Research Consortium, the rate of major stroke was 7.4 %, of life-threatening bleeding 7.4%, of kidney failure stage III 7.4%, and of major access site complication 11.1 %, respectively. Necropsy findings showed prosthesis malposition and perforation of the anterior mitral leaflet caused by the contact of the stent of the CoreValve prosthesis (Medtronic, Minneapolis, MN). PPM was defined as severe (indexed EOA <0.65 cm2/m2) or moderate (indexed EOA 0.65 to 0.85 cm2/m2). Transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve (MCV) system might represent an alternative to conventional redo surgery in older … Patients with severe PPM were more symptomatic and had a smaller indexed EOA at baseline than those with moderate or no PPM (0.28 ± 0.09 vs 0.36 ± 0.12 cm2/m2, p <0.05).
