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.
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.
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.
三尖瓣脱垂（TVP）的特征是在收缩中期三尖瓣小叶移位超出瓣环平面。虽然不如二尖瓣脱垂常见，但TVP常与之共存，具有相似的病理生理机制。本病例突出了心房扑动经腔静脉三尖瓣峡部消融术后新发三尖瓣反流（TR），强调了此类手术后需要密切监测。
一名68岁男性，患有心房扑动、冠状动脉疾病和2型糖尿病，在心率控制失败后于2023年8月接受了腔静脉三尖瓣峡部消融术。到2023年9月，他出现了4/6级收缩期杂音。影像学检查证实为TVP伴轻度至中度TR，尽管他仍无症状。采取了保守治疗。2024年10月的随访显示TR轻度且无脱垂，表明病情有所改善。
本病例强调了认识心房扑动消融术后瓣膜并发症以及进行全面的术后影像学检查以实现及时干预和改善预后的重要性。
