Minimally Invasive versus Conventional Mitral Valve Surgery Comparison of Early Outcomes

Abstract

Regarding intraoperative comparison, there was statistically significant difference in the cross-clamp time, total bypass time & total operation time. This difference may be due to the new experiences in this MIMVS and the lack of instrumentation that narrow the field of MIMVS. The length of the incision was highly significantly lesser in group ―I‖ than in group ―II‖. There was significant difference in the intensive care parameters. The mechanical ventilation time was shorter in group ―I‖ without significant difference, the blood loss and the blood transfusion required was lesser in group ―I‖. But the ICU stay was nearly the same in both groups. There was highly significantly less postoperative pain in group (I) than in group (II). There was no statistically significant difference as regards total hospital stay between both groups
