    A simple method for occlusion of both venae cavae in total cardiopulmonary bypass for robotic surgery
    (OXFORD UNIV PRESS, 2012-01-01) Gullu, Ahmet Umit; Senay, Sahin; Kocyigit, Muharrem; Alhan, Cem
    We describe a novel surgical technique for occlusion of the superior and inferior venae cavae which allows opening of the right atrium safely during robotic cardiac surgery.

    Robotic-assisted beating heart surgery provides precise repair of periprosthetic mitral valvular leak
    (OXFORD UNIV PRESS, 2022-01-01) Kocyigit, Muharrem; Gullu, Ahmet Umit; Senay, Sahin; Alhan, Cem
    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. The paravalvular leak is one of the most important complications of mitral valve replacement surgery with a prevalence of 2-13\% {[}1, 2].

    The feasibility of robotic-assisted concomitant procedures during mitral valve operations
    (BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2019-01-01) Gullu, Ahmet Umit; Senay, Sahin; Kocyigit, Muharrem; Okten, Eyup Murat; Dumantepe, Mert; Karabulut, Hasan; Alhan, Cem
    Background: In this study, we present our clinical experience and midterm results with the robotic-assisted concomitant procedures during mitral valve operations. Methods: Between March 2010 and February 2018, a total of 34 patients (8 males, 26 females
