Introduction:

Coronary artery bypass graft (CABG) surgery remains the reference standard in the treatment of multivessel coronary disease. Several studies have shown that CABG with bilateral internal mammary arteries (BIMA) has better results in long-term survival.

Methodology:

A retrospective study was conducted on CABG surgeries with BIMA from January 2012 to December 2015 in the National Cardiovascular Institute, INCOR, EsSalud, Peru. The objectives were to determine the mortality and major cardiovascular events at 30 days followup.

Results:

Of the 36 patients subjected to CABG surgery with BIMA, the 30-day mortality was 0%, with major cardiovascular events occurring in 5.56% of patients (Stroke 0%, postoperative myocardial infarction 5.56%, need of new coronary intervention 0%). The incidence of mediastinitis and/or sternal reconstruction was 0%. Superficial wound infection was observed in 7 patients, with there being no significant difference between diabetics and non-diabetics (25% vs. 16.66%, OR = 3.3, P = .88), or between patients with or without overweight (19.23% vs. 20%, respectively,OR = .95; 95% CI, P = .68).

Conclusions:

CABG surgery with BIMA is a safe procedure, with low rates of mortality and major cardiovascular events in the short-term. © 2016 Instituto Nacional de Cardiología Ignacio Chávez.
