Abstract
Objective
Hybrid coronary revascularization (HCR) combines both surgical and percutaneous coronary revascularization procedures. It offers a minimally invasive strategy for multivessel coronary artery disease and combines the advantages of both. However, quantitative long-term patency and clinical outcomes remain understudied. The objective of this study was to assess clinical outcomes and graft and stent patency at 5-year follow-up.
Methods
From January 2004 to January 2015, 120 patients were enrolled in this study. They underwent robotically assisted minimally invasive coronary artery bypass grafting of left internal thoracic artery (LITA) to the left descending artery (LAD) and percutaneous coronary intervention of non-LAD vessels. Primary outcome was graft (LITA-LAD) patency determined at 5 years of follow-up, assessed by computed tomography angiography and rest and stress myocardial perfusion scintigraphy (MPS-MIBI). Secondary outcomes were stent patency and major adverse major cardiac and cerebrovascular events (MACCE). Also, freedom from recurrence of angina was assessed.
Results
At follow-up, 18 of 120 patients (15%) had died (in 5 patients the cause of death was cardiovascular). Among survivors, follow-up was achieved in 83 of 102 (81%). In 76 of 83 patients (92%) there was a patent LITA-LAD graft and in 75 of 83 (90%) a patent stent was demonstrated. MACCE occurred in 36 of 120 patients (30%). Freedom from recurrence of angina occurred in 92 of 120 patients (77%).
Conclusions
HCR is a safe and a promising procedure. It provides a minimally invasive approach and results in complete revascularization with good 5-year patency and clinical outcomes.
