Abstract

Abstract: Background and aim of the study: Today there is little experience with minimally invasive treatment of multiple valve disease and no standard techniques have been provided yet. We report our early experience with combined aortic and mitral valve surgery with or without tricuspid surgery through a right lateral minithoracotomy (RmT), describing the technical aspects of our approach. Methods: From April 2017 to April 2019 thirty patients with mitro‐aortic valve disease or with triple valve pathology underwent surgery through a 3 to 4 cm lateral RmT into the third intercostal space. Cardiopulmonary bypass was established through femoral vessels cannulation. Surgery on the mitral valve (MV) was performed first and sutures put into the mitral annulus. Aortic valve replacement (AVR) was performed next. Then, the selected ring or prosthetic valve was implanted in a mitral position throughout previously placed sutures. Finally, if required, tricuspid valve surgery was performed. Results: In combined with AVR, MV replacement was performed in 20 patients (66%), and MV repair in 10 patients (34%). Concomitant tricuspid annuloplasty was performed in five patients (17%). There was no conversion to full sternotomy. Postoperatively, one patient died. Postoperative echocardiography showed no perivalvular leakage in aortic or in the mitral position. No residual mitral regurgitation was observed in patients who underwent MV repair. Conclusions: Minimally invasive surgery of double and triple valve disease is feasible. Our approach through a lateral RmT allows optimal visualization of the aortic, mitral, and tricuspid valves, simplifies the surgical procedure and allows excellent results also in complex MV repair procedures.
