Results of minimally invasive video-assisted mitral valve replacement via right mini-thoracotomy
Main Article Content
Abstract
Minimally invasive mitral valve surgery has been implemented in Vietnam recently, however the data
of postoperative mid-term and long-term follow-up is limited. We conducted a study to evaluate the early
and mid-term results of minimally invasive mitral valve replacement in Bach Mai hospital. From January
2018 to May 2020, 85 patients underwent mitral valve replacement via right mini-thoracotomy at Vietnam
National Heart Institute. We analyzed early postoperative outcomes, including 30 - days mortality and
mid-term results. Our cohort included 85 patients with 41.2% of males, and the mean age of 52.2 ± 8.4
years. Mean cardiopulmonary bypass time of 95.2 ± 17.5 min, and cross-clamp time of 63.7 ± 14.6 min.
Mean mechanical ventilation time was 17.2 ± 29.3 hours, intensive care unit length of stay was 57.0 ± 80.8
hours, and hospital length of stay was 11.8 ± 5.4 days. Major early postoperative complications included:
conversion to sternotomy was required in 1 patient (1.2%), re -exploration for bleeding 2 patients (2.4%),
early mortality 1 patient (1.2%) and no cerebrovascular accidents occurred. 84 patients were followed
up with average period of 14.4 ± 8.0 months. One patient (1.2%) died during follow - up, re - operation
in 3 patients (3.6%). Early and mid-term results for our minimally invasive mitral valve replacement are
acceptable, encouraging and promising. However, the patients need to be followed up for long term result.
