Balloon-Expandable Versus Self-Expanding Transcatheter Aortic Valve Replacement: A Propensity-Matched Comparison From the FRANCE-TAVI Registry.

Background: No randomized study powered to compare balloon expandable (BE) with self expanding (SE) transcatheter heart valves (THVs) on individual end points after transcatheter aortic valve replacement has been conducted to date.

Methods: From January 2013 to December 2015, the FRANCE-TAVI nationwide registry (Registry of Aortic Valve Bioprostheses Established by Catheter) included 12 141 patients undergoing BE-THV (Edwards, n=8038) or SE-THV (Medtronic, n=4103) for treatment of native aortic stenosis. Long term mortality status was available in all patients (median 20 months; interquartile range, 14 to 30).

Multiobjective patient-specific estimation of a coronary circulation model for triple vessel disease.

Computational models can help understand the hemodynamics of the coronary circulation, which is of the upmost importance to help clinicians before, during and after a coronary artery bypass graft surgery. In this paper, we propose a multiobjective optimization method for parameter estimation of a computational model representing the coronary circulation on patients with a triple vessel disease. This estimation was not based on any assumption regarding the development of the collateral circulation, like in previous works.

Complicated acute type B aortic dissection: midterm results of emergency endovascular stent-grafting.

Objective: This study assessed midterm results of emergency endovascular stent-grafting for patients with life-threatening complications of acute type B aortic dissection.

Methods: Between November 1996 and June 2004, 16 patients with complicated acute type B aortic dissections (mean age 57 years, range 16-88 years) underwent endovascular stent-grafting within 48 hours of presentation. Complications included contained rupture, hemothorax, refractory chest pain, and severe visceral or lower limb ischemia.
