Video-Assisted Mini-Thoracotomy Versus Anterior Thoracotomy Mitral Valve Replacement: Intraoperative Time and Hospitalization

Abstract

Objectives: Minimally invasive mitral valve surgery (MIMVS) was introduced to avoid a full sternotomy through smaller or alternative chest wall incisions to reduce complications. We present our experience with MIMVS through two of its techniques. Methods: This prospective single-centre study was conducted on a total of 34 cases, divided into two groups: Group A (VAMVR) included 17 patients who underwent video-assisted mitral valve replacement. Group B (ATMVR) included 17 patients who underwent right anterior thoracotomy mitral valve replacement, comparing intraoperative procedures and the results of both techniques .Results: In the studied cases, the mean intraoperative time was 4.38 ± 0.69 hours, which widely ranged from 3 to 6 hours, with no significant difference between both techniques. It was 4.35 ± 0.7 hours in VAMVR and 4.41 ± 0.7 in ATMVR. mean ventilation time of 3.96 ± 1.08 hours. The mechanical ventilation time was 4.24 ± 1.1 hours in VAMVR cases and 3.68 ±1.1 hours in the ATMVR group. The mean overall ICU stay duration was 1.75 ± 0.33 days, with no impact of the technique used on this time, as it was 1.71 ± 0.25 days in VAMVR patients and 1.79 ± 0.4 in ATMVR patients. The total hospital stay time was about 5.71 ± 0.91 days, ranging from 4 to 8 days, with no impact of the procedure used on this time as it was 5.6 ± 0.94 days in VAMVR cases and 5.8 ± 0.88 days in ATMVR cases.

Conclusions: There was no impact of the technique used in MIMVS, whether video-assisted or right anterior thoracotomy mitral valve replacement, on intraoperative time and ICU and hospital stays.
