Transcatheter transfemoral aortic valve replacement in a patient with acromegaly and severe left ventricular myocardial hypertrophy. Case report

Abstract

Main causes of secondary hypertrophic cardiomyopathy include acromegalic cardiomyopathy. Heart damage in patients with the acromegaly is mediated both by the direct action of growth hormone and insulin-like growth factor-1, and increased deposition of collagen and lymphomononuclear cells in the myocardium, which leads to architectural changes, disturbances in fluid and electrolyte balance, severe left ventricular myocardial hypertrophy, diastolic and systolic left ventricular dysfunction and chronic heart failure. This article presents the world's first described observation demonstrating the possibility of successful transfemoral aortic valve repair to a comorbid patient with severe aortic stenosis according to the potential risks caused by the active form of the acromegaly.
