The session provided both an update on the current status of percutaneous valve therapy, as well as a summary on the utilization of imaging modalities in patient selection for these therapies.

Dr. Vahanian from France provided an excellent overview on the current status of percutaneous mitral valve therapy. The techniques are rapidly developing and are focused on percutaneous repair and replacement of the mitral valve. Specifically in severe heart failure patients, therapeutic options for mitral regurgitation are limited and percutaneous repair with the mitraclip procedure may provide a valuable option.

The second lecture was provided by Dr. Erbel from Germany, and the topic was the current status of percutaneous aortic valve therapy. The large trials that were recently published were summarized, and a large European registry was presented. Clearly, this therapy is more and more implemented in the clinical routine. Importantly, Dr. Erbel indicated that specific guidelines are needed to determine the precise target population; in the perspective, it is worth mentioning that ESC will issue the new valve guidelines in 2012.

The last 2 lectures were provided by Dr. Tuzcu from the United States, who carefully evaluated the role of the different imaging techniques in percutaneous valve therapy. It has become evident that imaging is needed in patient selection, but also during the procedure and at systematic predefined follow-up moments. Cardiac CT is extremely useful in patient selection, both for percutaneous mitral valve and aortic valve therapy. This technique provides the best anatomic information; a good alternative is provided by MRI. Echocardiography (particularly 3D echo) is used during prior to and during the procedure. Finally, fluoroscopy is needed during the procedures. The conclusion from these 2 lectures by Dr. Tuzcu was that an excellent collaboration between invasive and non-invasive cardiologists is needed.
