Minimally Invasive Video-assisted Mitral Valve Surgery: The Impact Of Aortic Clamping Technique

Aim of the study is evaluate the clinical outcome,in a single center experience,of endo-aortic or transthoracic clamp strategy,in minimally invasive video-assisted mitral valve surgery (MIMVS).Materials and methods:We retrospectively analyzed 55 patients underwent to MIMVS between 2014 and 2018. We used in 33 patients endo-aortic balloon occlusion technique(EAC) with Intraclude© and in 22 transthoracic clamp technique(TTC) with Cygnet©.Results:Surgical operations were in 23 patients mitral repair and in 32 mitral replacement.There were no differences between groups for CPB-time(137 ± 37 EAC vs 141 ± 39 TTC, p-value = 0,866) and clamping-time(87 ± 31 vs 90 ± 21,p-value = 0,329);incidence of peri-operative acute myocardial infarction was null,even if the post-operative CPK-MB are out of normal range.The 24h-blood loss was higher in EAC-group(817 ± 506 vs …
