AIMS: Transcatheter mitral valve implantation for mitral valve regurgitation is in the very early phase of development because of challenging anatomy and device dimensions. We describe the procedure of a transfemoral-transseptal implantation of the second-generation CardiAQ mitral valve bioprosthesis and 30-day follow-up.
METHODS AND RESULTS: The procedure was performed percutaneously, without any left extracorporeal circulatory support. The patient had severe mitral regurgitation with severely depressed ventricular function and other comorbidities. The patient was deemed extreme high risk for conventional cardiac surgery by a multidisciplinary team. The main procedural steps were the creation of an arteriovenous loop with an exchange nitinol wire, and the use of a customised "steerable snare system" to facilitate the catheter delivery system into the mitral annulus. Transoesophageal echocardiography and fluoroscopy were utilised for device positioning and deployment. The mitral valve prosthesis was implanted with mild mitral regurgitation. The postoperative course was uneventful and at 30-day follow-up the patient is in NYHA Class I, with good function of the mitral valve bioprosthesis.
CONCLUSIONS: This procedure shows that percutaneous transfemoral transcatheter mitral valve implantation is feasible, safe and successful. Further experience is needed to render this procedure clinically available.
