Key result
Transcatheter aortic valve replacement (TAVR) was followed by hemodynamically unstable atypical atrioventricular nodal reentrant tachycardia with aberrancy in an 84-year-old female.
Why the study?
Despite the advantages of TAVR over SAVR, clinicians must remain aware of post-procedural complications, including diagnostic challenges in differentiating wide complex tachycardias.
Case Report (n=1)
This case highlights the rare occurrence of hemodynamically unstable AVNRT with aberrancy following TAVR and demonstrates the critical utility of ICD interrogation in differentiating it from ventricular tachycardia.
Post-TAVR wide-complex tachycardia in ICD recipients warrants device interrogation; single case leaves open systematic incidence and management data.
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.

Fahed et al. (2025) conducted a case report in Severe aortic stenosis and post-TAVR arrhythmia (n=1). Transcatheter aortic valve replacement (TAVR) was evaluated. Transcatheter aortic valve replacement (TAVR) was followed by hemodynamically unstable atypical atrioventricular nodal reentrant tachycardia with aberrancy in an 84-year-old female.
