OBJECTIVES: To summarize our single Institution experience with staged total percutaneous management of aorto-mitral pathology.

BACKGROUND: Percutaneous treatment of aortic valve stenosis (AVS) and mitral valve regurgitation (MVR) has been recently proposed for patients at high surgical risk.

METHODS: Data concerning consecutive patients undergoing percutaneous transcatheter AV implantation (TAVI) followed by MV repair with MitraClip® were prospectively collected and analyzed.

RESULTS: From January 2010 to February 2012 a total of 254 patients were referred to undergo TAVI in our Institution. Seventeen (6.7%) had preoperative severe MVR that remained unchanged after TAVI. Due to exacerbation of symptoms 12 patients were subsequently submitted to MV repair with the MitraClip® device. Mean age was 79 years (72-86 years), median Ambler score was 30.1 (17.2-42.6) and EuroSCORE 22.3 (10.2-48.6). Procedural success rate was 100%. Postprocedural hospitalization was 7.1 ± 2.7 and 4.6 ± 0.9 days after TAVI and MV repair, respectively. Six months follow-up echocardiography confirms improvement in LV-EF (37.2 ± 9.9 vs. 43.5 ± 10.7, P < 0.0001). No patient presents MVR exceeding grade I(+) or prosthetic aortic insufficiency > I grade and all patients experienced an improvement in functional status.

CONCLUSIONS: Percutaneous treatment of AVS and MVR is feasible and safe. A tailored approach should be considered to treat firstly the AVS and subsequently the MVR when severe MV dysfunction and symptoms persist. Short-term durability of this combined percutaneous approach seems encouraging and justifies the economical burden to treat patients that have no other option.
