With an increased number of surgical procedures involving the mitral annular region, the risk of mitral valve prolapse (MVP) has also increased. Previous studies have reported that worsening of MVP occurred early after radiofrequency catheter ablation (RFCA) at papillary muscles in ventricular tachycardia (VT) patients with preoperative MVP.
We report a case where MVP and papillary muscle rupture occurred 2 wk after RFCA in a papillary muscle originated VT patient without mitral valve regurgitation or prolapse before. The patient then underwent mitral valve replacement with no premature ventricular contraction or VT. During the surgery, a papillary muscle rupture was identified. Pathological examination showed necrosis of the papillary muscle. The patient recovered after mitral valve replacement.
Too many ablation procedures and energy should be avoided.
Core Tip: The risk of early mitral valve prolapse (MVP) increases after radiofrequency catheter ablation (RFCA). However, the delayed MVP after RFCA was not reported before. We report the first case of delayed MVP after RFCA and analyze the reason.
