Robotic-assisted beating heart surgery provides precise repair of periprosthetic mitral valvular leak

The prosthetic paravalvular leak is a rare but important complication following mitral valve replacement. Determining the location of the leak is almost always dependent on perioperative transoesophageal echocardiography and the considerable expertise of echo operators. Acoustic shadowing due to the prosthetic valve may create another important difficulty. In this report, we present a case with a paravalvular leak diagnosed 1 year after mitral valve replacement. Beating heart surgery and robotic 3D/high-resolution camera provided to localize the direct location of leak coherent with perioperative echocardiography and precise repair. The robotic approach prevented the potential complications of aortic cross-clamp and resternotomy.
