Long -term clinical benefit of bilateral internal mammary artery for isolated total arterial revascularization
Main Article Content
Abstract
Background: we aim to evaluate the long-term outcomes of using Bilateral Internal Mammary Artery (BIMA) for Total Arterial Revascularization (TAR) in coronary artery bypass.
Methods: we conducted a single- center retrospective observational study between 2008-2017 at Ho Chi Minh City Heart Institute-Viet Nam. All patients in study used only BIMA for isolated coronary artery bypass.[1]
Results: total number of patients and mean age were 246 and 61 ± 9.1 years. Male patient was 72.3%. Pre-operation, the incidence of unstable angor is 72% and the mean of EuroScore II is 2.53. All patients had 3-vessel disease with 32% had left main stenosis. The mean bypass was 3.3 ± 0.55 per patient. In-Hospital mortality was 1.6% (4). Mean time follow-up was 65.9 ± 40.3 months. Late death was 15 patients (6%) among that, there has 9/15 with cardiovascular related death. Incidence of recurrent chest pain with evidence in angiography was 10. Only 4 patients had to revascularization by PCI. Overall Kaplan-Meier 12-years survival rate was 89.1 ± 3.8% and freedom from reintervention rates for all patients was 87.8 ± 6.3%.
Conclusions: isolated TAR by BIMA are safe, effective and providing good long-term clinical outcomes in the treatment of 3-vessel coronary disease.
