- W3000488941 abstract "Abstract Funding Acknowledgements none Background Right side heart valve involvement is a well known phenomenon in metastatic carcinoid disease. In recent times bioprosthetic valves have been widely used for replacement of stenotic and regurgitant native heart valves. Melody Transcatheter Pulmonary Valve (MTPV, Medtronic, Minneapolis, MN, USA) has been approved for treatment of native pulmonary valves as well as failing biological prostheses and conduits. We present the first case to our knowledge of severe native pulmonary valve steno-insufficiency due to metastatic carcinoid syndrome treated with MTPV implantation. Case report A 57-year-old woman is known since 2007 for metastatic carcinoid syndrome treated with surgical resection followed by chemotherapy (tamoxifene, everolimus) and radiotherapy. For 2 years she has been known for tricuspid and pulmonary involvement, which aggravated progressively, leading to symptomatic right heart failure. She was therefore submitted for multimodality imaging evaluation (see picture) and right heart catheterization. Transthoracic echocardiogram, cardiac MRI and right heart catheterization confirmed severe pulmonary valve steno-insufficiency. Cardiopulmonary exercise testing revealed a severe limitation of aerobic exercise capacity (VO2 max 14.4 ml/min/kg). After heart team discussion it was decided to treat the patient in a 2 step approach, initially with implantation of a Melody valve in pulmonary position and subsequently with surgical repair of the tricuspid valve. Pulmonary valve was treated by placement of a 39 x 25 mm ANDRA stent and subsequent implantation of a 22 mm Melody valve. Before stenting, coronary angiography with simultaneous balloon inflation in RVOT was performed to exclude coronary artery compression. During the procedure the patient developed hypotension, which was treated effectively with Octeotride. Post-operative echocardiogram showed a significant reduction in pulmonary valve gradient and no significant residual regurgitation. Conclusions We treated effectively severe pulmonary steno-insufficiency due to metastatic carcinoid tumor with MTPV implantation. No complications occurred. Multimodality imaging is fundamental for patients selection and preoperative planning of prosthetic valve dimensions. Abstract P641 Figure. Multimodality imaging of PV" @default.
