Simplified three-dimensional spatial approach for improving confidence in reliably measuring left ventricular linear internal dimensions
Abstract
Introduction Current guidelines indicate that surgery should be considered in asymptomatic patients with chronic severe aortic or primary mitral regurgitation with severe left ventricular dilatation, and specifically when indicated cut-offs are reached or overcome. For asymptomatic severe aortic regurgitation with resting ejection fraction more than 50%, such cut-offs are left ventricular end-diastolic diameter (LVEDD) more than 70 mm or left ventricular end-systolic diameter (LVESD) more than 50 mm (or LVESD>25 mm/ m body surface area (BSA) in patients with small body size), Class of Recommendation IIa, Level of evidence B.
