Key result
Cavotricuspid isthmus ablation linked to new-onset tricuspid valve prolapse and tricuspid regurgitation.
Why the study?
New-onset tricuspid regurgitation following cavotricuspid isthmus ablation for atrial flutter is poorly recognized, highlighting the need for vigilant post-procedural monitoring.
Case Report (n=1)
Cavotricuspid isthmus ablation for atrial flutter can be complicated by new-onset tricuspid valve prolapse and regurgitation, highlighting the need for post-procedural monitoring.
May signal rare CTI ablation-related tricuspid injury warranting post-procedure echo; leaves open incidence and causality.
Introduction: Tricuspid valve prolapse (TVP) is characterized by the tricuspid valve leaflets' displacement beyond the annular plane during midsystole. Although less common than mitral valve prolapse, TVP often coexists with it, sharing similar pathophysiological mechanisms. This case highlights new-onset tricuspid regurgitation (TR) following cavotricuspid isthmus ablation for atrial flutter, stressing the need for vigilant monitoring after such procedures. Case: A 68-year-old male with atrial flutter, coronary artery disease, and type 2 diabetes underwent cavotricuspid isthmus ablation in August 2023 after failed rate control. By September 2023, he developed a grade 4/6 systolic murmur. Imaging confirmed TVP with mild to moderate TR, though he remained asymptomatic. Conservative management was adopted. Follow-up in October 2024 showed mild TR without prolapse, indicating improvement. Conclusion: This case underscores the importance of recognizing valvular complications after atrial flutter ablation and conducting thorough post-procedural imaging to enable timely intervention and improved outcomes.

Pineda-Sanabria et al. (2025) conducted a case report in Atrial flutter and new-onset tricuspid regurgitation (n=1). Cavotricuspid isthmus ablation was evaluated on New-onset tricuspid regurgitation and tricuspid valve prolapse. Cavotricuspid isthmus ablation was followed by a grade 4/6 systolic murmur and new-onset tricuspid valve prolapse with mild to moderate tricuspid regurgitation in a 68-year-old male.
