“…From 2009 to March 31, 2018, 66 published reports describing 172 patients undergoing TMVIV implantation for degenerated mitral bioprostheses and 35 articles describing 73 patients undergoing TMVIR implantation for failed annuloplasty rings were identified (Figure ). The patients were diagnosed with MR, MS, or mixed lesions according to the articles but the failure modes of 34 patients were unknown.…”

“…A total of nine articles reported variable positions. The three different positions of the ES valve are as follows: (1) less atrium more ventricle: 1/3 in the atrium and 2/3 in the ventricle or 40% in the atrium and 60% in the ventricle; (2) half above and half below the mitral ring; (3) more atrium less ventricle: 40% ventricular and 60% atrial configuration . Two articles reported the position of the Melody valve as follows: 20% in the atrium and 80% in the ventricle and 40% in the atrium and 60% in the ventricle .…”

BackgroundTranscatheter mitral valve‐in‐valve (TMVIV) and valve‐in‐ring (TMVIR) implantation for degenerated mitral bioprostheses and failed annuloplasty rings have recently emerged as treatment options for patients deemed unsuitable for repeat surgery.MethodsA systematic literature review was conducted to summarize the data regarding the baseline characteristics and clinical outcomes of patients undergoing TMVIV and TMVIR procedures.ResultsA total of 245 patients (172 patients who underwent TMVIV surgery and 73 patients who underwent TMVIR surgery) were included in the study; 93.5% of patients experienced successful TMVIV or TMVIR implantation. The mortality rates at discharge, 30 days, and 6 months were 5.7%, 8.1%, and 23.4%, respectively. The transapical (TA) access route was used in most procedures (55.2%). The TA and transseptal (TS) access routes resulted in similar outcomes. No significant differences were observed in the short‐term outcomes between the patients who developed mitral stenosis versus mitral regurgitation as the mode of failure.ConclusionsTMVIV and TMVIR implantation for degenerated mitral bioprostheses and failed annuloplasty rings are safe and effective. Both procedures, via TA or TS access, can result in excellent short‐term clinical outcomes in patients with mitral stenosis or regurgitation, but long‐term follow‐up data are currently lacking to determine the durability of these procedures.
