Transcatheter aortic valve replacement for aortic regurgitation secondary to aortic sinus dilation with incidentally detected aortic chordae tendineae: case report.

ABSTRACT:

Introduction

Aortic chordae tendineae (ACT) are rare fibrous strands originating from early aortic valve cusp formation as embryonic remnants. Most aortic chordae tendineae are asymptomatic, but they may cause aortic regurgitation via chordal rupture or cusp restriction. This case presents transcatheter aortic valve replacement (TAVR) for aortic regurgitation secondary to aortic sinus dilation with incidentally detected ACT that did not directly contribute to valvular dysfunction.

Patient presentation

An 81-year-old female with hypertension presented with progressive dyspnea. Cardiac auscultation revealed a diastolic murmur over the left sternal border. Transthoracic echocardiography demonstrated severe aortic regurgitation due to significant aortic root dilatation. Transapi
