Minimally invasive direct coronary artery bypass (MIDCAB) – safety assessment in own material.

Introduction: Minimally invasive direct coronary artery bypass (MIDCAB) allows achieving similar safety and efficacy, with markedly reduced post-operative length of stay when compared to conventional surgical revascularization. Despite promising results, a small number of minimally invasive procedures are performed in Poland. The aim of the study is to assess short- and long-term outcome of MIDCAB revascularization in order to evaluate the safety of the procedure.

Materials and methods: Retrospective observational study analyzing 38 consecutive patients who underwent MIDCAB procedure between 2014 to 2016 in the Department of Cardiovascular Surgery and Transplantology at the John Paul II Hospital, Kraków. Perioperative data was obtained from patient medical records and the median follow-up period valued 17.3 months.

Results: No postoperative deaths and only 1 case of postoperative myocardial infarction were observed. Throughout the follow-up period, the survival rate and freedom from MACCE rate valued 100%, with only 1 case of repeated revascularization.

Conclusions: Minimally invasive revascularization is a safe procedure which can be performed with excellent short- and long-term outcome in low-risk patients.
