A 65-year-old Caucasian male was referred to our institution with severe mitral regurgitation due to posterior mitral leaflet prolapse. The patient underwent minimally invasive surgical mitral valve repair. Here we present the application of a new vascular closure device (MANTA) for percutaneous arterial access and closure.

AbstractMinimally invasive surgery is increasingly utilized for mitral valve repair and replacement. The intervention is performed with an endoscopic field of view on the arrested heart. Extracting the necessary information from the live endoscopic video stream is challenging due to the moving camera position, the high variability of defects, and occlusion of structures by instruments. During such minimally invasive interventions there is no time to segment regions of interest manually. We propose a real-time-capable deep-learning-based approach to detect and segment the relevant anatomical structures and instruments. For the universal deployment of the proposed solution, we evaluate them on pixel accuracy as well as distance measurements of the detected contours. The U-Net, Google’s DeepLab v3, and the Obelisk-Net models are cross-validated, with DeepLab showing superior results in pixel accuracy and distance measurements.

Mitral Repair

Bulging subaortic septum in hypertrophic cardiomyopathy is a potential risk factor for systolic anterior motion after mitral valve repair. Systolic anterior motion may cause postoperative mitral regurgitation and left ventricular outflow tract obstruction despite conservative management. During “minimally invasive endoscopic” and “robotic” mitral repair procedures, systolic anterior motion is prevented with concomitant septal myectomy through the mitral valve orifice. Technically, the exposure of the bulging subaortic septum is traditionally done with detachment of the anterior mitral leaflet from its annulus, leaving a 2-mm rim of leaflet attached to the annulus. The leaflet is then sutured after myectomy. As an alternative technique in robotic surgery, the exposure of the subaortic septum is feasible without anterior leaflet incision with the use of dynamic atrial retractor in mitral repair procedures. Here, we present a patient who underwent concomitant robotic mitral valve repair with posterior chordal implantation, ring annuloplasty, and septal myectomy without anterior leaflet incision using the da Vinci surgical system.
