High-Degree Atrioventricular Block and Torsades De Pointes in Severe Aortic Stenosis Treated With Transcatheter Aortic Valve Replacement

TL;DR

This case report shows how severe aortic stenosis can lead to dangerous heart rhythm issues, emphasizing the need for careful management.

Contribution

The novelty lies in illustrating the clinical connection between severe aortic stenosis, high-degree AV block, and torsades de pointes.

Findings

Severe aortic stenosis can lead to high-degree AV block.

High-degree AV block may trigger torsades de pointes in patients with severe aortic stenosis.

Abstract

Severe aortic stenosis (AS) significantly elevates cardiovascular risk, predisposing patients to high-degree atrioventricular (AV) block and life-threatening tachyarrhythmias, including torsades de pointes (TdP). This case report presents a patient with severe AS who developed high-degree AV block and, subsequently, TdP, highlighting the interplay between bradycardia and mechanisms that trigger ventricular tachycardias. The case underscores the importance of identifying and managing these risk factors to improve patient outcomes.
