To compare safety, efficacy, and hemodynamics of transfemoral transcatheter aortic valve replacement (TAVR) using self-expanding and balloon-expandable transcatheter heart valves (THVs) in patients with a small aortic annulus. Few studies have directly compared TAVR outcomes using third-generation THVs, focusing on patients with small aortic annuli...

ObjectiveEnlargement of the aortic annulus may be required during aortic valve replacement to avoid patient–prosthesis mismatch. We reviewed patients with enlargement of the aortic annulus with the aim of assessing the stability of the procedure by means of echocardiographic and angio–computed tomography studies. MethodsA series of 53 consecutive p...

Background How best to define patient-prosthesis mismatch (PPM) continues to be debated. Over time, the indexed effective orifice area has become the most widely used method. However, the clinical relevance of PPM remains controversial. Methods The indexed geometric orifice area and indexed effective orifice area were calculated for 143 patients ha...
