David aortic valve-sparing reimplantation versus biological aortic root replacement: a retrospective analysis of 411 patients.

Objectives: This study aimed to compare short- and long-term results for patients undergoing either aortic valve-sparing reimplantation (David) procedure (AVr-D) or biological aortic root replacement (Bentall) procedure (ARr-B-bio) for aortic root pathology.

Methods: We compared outcomes for patients who underwent AVr-D ( = 261) or ARr-B-bio ( = 150) between 2000 and 2015 at our institution. The mean age of patients was 55 ± 13 years and 21.

Minimally invasive mitral valve repair.

Minimally invasive mitral valve (MV) repair is being increasingly performed over the last 2 decades due to the constantly growing patient demand, since it offers a shorter recovery, less restriction and faster return to normal physical activities, reduction in pain, and superior cosmetic results. However, such procedures have to be performed through small incisions which limit visualization and the freedom of movement of the surgeon, in contrast to conventional operations that are performed through a sternotomy. Therefore, special long surgical instruments are required, and visualization is usually enhanced with advanced port-access two-dimensional (2D) or three-dimensional (3D) thoracoscopic cameras.
