Abstract
Introduction The orifice area of heart valve bioprostheses is important to evaluate their hemodynamic performance. However, its calculation using transthoracic echocardiography (TTE) is frequently complicated due to limited acoustic windows and methodical concerns. Regarding aortic bioprostheses, cardiovascular magnetic resonance (CMR) has recently been established as an alternative tool to assess the orifice area. Yet, in mitral position, annular plane excursion and frequent coincident arrhythmias raise concerns whether CMR can be applied likewise.
