Early outcomes of minimally invasive hybrid coronary revascularization

Abstract

Background: Coronary artery bypass graft (CABG) surgery has been the gold standard for the treatment of coronary artery disease over the years. It is recommended for patients with multi-vessel coronary artery disease, left main disease, diabetics, severe left ventricular dysfunction, unsuitable anatomy for percutaneous coronary intervention (PCI), and failed PCI. The usage of the left internal mammary artery (LIMA) in the CABG to the left anterior descending (LAD) artery has proven to be superior compared to PCI. Minimally invasive hybrid coronary revascularization (MIHCR) is gaining growing interest. Methods: This is a hospital-based prospective observational study with 200 patients followed up for a period of 30 days. This study aims to assess the early outcomes of MIHCR in the Indian population. Results: The 30-day mortality was comparable to other studies, and the number of days in the ICU and hospital stay was shorter than the routine CABG. There was no incidence of a wound infection or stroke. Blood product usage and the need for repeat revascularization and re-exploration were less. The short-term outcomes were promising. Conclusions: MIHCR has excellent short-term results and is safer than conventional OPCABG, as it is less invasive and avoids midline sternotomy. It also reduces the incidence of stroke and lesser usage of blood products, promoting early return of patients to their routine activities.
