Sumario:BACKGROUND: Transcatheter mitral valve in ring procedure has emerged as a minimally invasive alternative to re-do surgery among patients with failed mitral annuloplasty rings. Uncommonly, haemolysis presents as a complication after the percutaneous valvular procedures and often require aggressive measures to correct paravalvular leaks and mechanical collision. CASE SUMMARY: We report a case of an 82-year-old female who underwent a transcatheter valve in ring procedure (Edwards Sapien S3, Edwards Lifesciences) for symptomatic severe mitral regurgitation from a bioprosthetic annuloplasty ring failure complicated by acute haemolytic anaemia a week after the procedure manifesting as dark coloured urine, profound icterus, and acute renal injury. She was treated with a post-dilation balloon valvuloplasty leading to reduction in haemolysis, but the patient was readmitted with acute haemolysis episode again. At this time, a decision was made to perform a repeat valve in valve TMVR with a 29 mm S3 Edwards Sapien valve which led to a resolution of haemolysis. DISCUSSION: In this case, the leaflets of previously placed S3 valve sealed the blood flow through the valve frame thus diverting the blood flow away from the area of collision leading to resolution of haemolysis.
