# Transcatheter Aortic Valve Replacement (TAVR)-Induced Hemodynamically Unstable Supraventricular Tachycardia in an Elderly Patient With a Complex Cardiovascular History

## TL;DR

This paper describes a case where TAVR led to a rare heart rhythm issue in an elderly patient with a complex medical history.

## Contribution

The novelty lies in highlighting a rare arrhythmia complication after TAVR and the role of an ICD in diagnosing and confirming its link to the procedure.

## Key findings

- An elderly patient developed hemodynamically unstable supraventricular tachycardia weeks after TAVR.
- The ICD was crucial in differentiating the arrhythmia and establishing its temporal link to the TAVR procedure.

## Abstract

Transcatheter aortic valve replacement (TAVR) is an important alternative to surgical aortic valve replacement (SAVR) as it reduces stay length and complication rates. Despite this apparent advantage, clinicians must still be aware of these complications. In this paper, we present a case of an elderly female who had an ICD placed years before presentation, presenting with wide complex tachycardia weeks after the TAVR procedure. In this case, the differentiation between ventricular tachycardia and supraventricular tachycardia with aberrancy proved to be a diagnostic challenge. This case highlights an arrhythmia-related complication stemming from TAVR and the utility of the Implantable cardioverter defibrillator (ICD) as an important diagnostic tool in differentiating these rhythms and confirming the temporal relationship between this arrhythmia and the valve replacement procedure.
