Given her extremely high surgical risk, transcatheter edge-to-edge mitral valve repair with the MitraClip® device was selected as the most appropriate therapeutic option. The procedure was technically challenging due to altered post-transplant anatomy, but it was completed successfully without immediate complications and resulted in a substantial reduction in regurgitation. During early follow-up, a small left atrial thrombus was identified and subsequently resolved after a six-week course of oral anticoagulation. This report illustrates the feasibility and safety of transcatheter mitral repair in carefully selected heart transplant recipients and underscores the importance of tailored post-procedural surveillance in this complex population.  \nCategories: Cardiology, Cardiac/Thoracic/Vascular Surgery, Transplantation  \nKeywords: case report, heart transplantation, left atrial thrombus, mitraclip, mitral regurgitation, percutaneous edge to edge repair  \nIntroduction  \nMitral regurgitation (MR) in heart transplant recipients may result from annular dilation, graft dysfunction, or leaflet tethering [1] . Surgical correction is associated with substantial perioperative risk due to prior sternotomies, adhesions, and comorbidities related to chronic immunosuppression [2] . Transcatheter mitral valve repair with the MitraClip® system has emerged as a valuable alternative for patients with symptomatic severe MR who are considered prohibitive surgical candidates; however, published experience in the transplant population remains limited [3,4] . We describe a technically demanding but successful MitraClip® procedure in a long-term heart transplant recipient and discuss thrombotic surveillance and management considerations in this unique clinical setting.  \nCase Presentation  \nA 62-year-old female with a history of orthotopic heart transplantation in 2006 for chemotherapy-induced cardiomyopathy and maintained on routine post-transplant follow-up presented with progressive exertional dyspnea (New York Heart Association class III) and worsening MR on serial transthoracic echocardiograms.  \nHer medical history included stage IV chronic kidney disease with a stable estimated glomerular filtration rate of 35 ml/min/1 .73 m², prior endovascular aortic repair, and coronary stenting. Maintenance  \nimmunosuppression consisted of mycophenolate mofetil and everolimus. On March 15, 2024, transesophageal echocardiography (TEE) demonstrated preserved left ventricular ejection fraction (65%) and severe MR secondary to fibro-degenerative valve leaflet alterations, including posterior leaflet hypomobility and marked left atrial enlargement. Doppler indices suggested elevated left ventricular filling pressures  \nwithout evidence of pulmonary hypertension.  \nFollowing Heart Team evaluation, the patient was deemed high surgical risk, and transcatheter edge-to  \nedge repair (TEER) with the MitraClip system was planned","cbCaieutVcyWxyJL","https://ap.wps.com/l/cbCaieutVcyWxyJL","pdf",1858183,"English","# Abstract\n# Introduction\n# Case Presentation\n# How to cite this article\n# Figures","[{\"question\":\"Why was MitraClip® considered for this patient instead of surgery?\",\"answer\":\"The patient had extremely high surgical risk, making transcatheter edge-to-edge repair with the MitraClip® device the most appropriate option.\"},{\"question\":\"What made the MitraClip® procedure technically challenging?\",\"answer\":\"Altered post-transplant anatomy distorted access, making septal crossing and leaflet grasping difficult and requiring multiple attempts.\"},{\"question\":\"What complication occurred during early follow-up and how was it managed?\",\"answer\":\"A small left atrial thrombus was identified and resolved after a six-week course of oral anticoagulation.\"}]","Transcatheter Mitral Valve Repair With MitraClip® in a Heart Transplant Recipient - Pushing the Limits of Percutaneous Valve Therapy | PDF"]
