Summary

Minimally invasive direct coronary artery bypass grafting using the gastroepiploic artery showed an 88% symptom resolution rate. However, lower-than-expected patency rates and significant morbidity/mortality were observed in high-risk patients.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Cardiac Surgery

Background:

  • Minimally invasive direct coronary artery bypass grafting (MIDCAB) with the gastroepiploic artery is an option for revascularizing specific heart surfaces.
  • This technique is applicable in both primary operations and reoperations.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of gastroepiploic artery MIDCAB.
  • To assess graft patency, morbidity, and mortality in patients undergoing this procedure.

Main Methods:

  • Seventy-four patients with single-coronary-distribution symptomatic coronary artery disease underwent MIDCAB using the gastroepiploic artery.
  • Grafting targeted the distal right coronary artery, posterior descending artery, or distal left anterior descending coronary artery.
  • Patients were followed with clinical visits, Doppler, and selective recatheterization.

Main Results:

  • The study included 33 primary operations and 41 reoperations.
  • Six perioperative deaths (8%) occurred.
  • Recatheterization in 28% revealed graft and anastomotic stenoses.
  • At a mean follow-up of 10.9 months, 88% of patients experienced symptom resolution.

Conclusions:

  • Gastroepiploic artery MIDCAB can avoid sternotomy and cardiopulmonary bypass risks.
  • Observed patency rates were lower than anticipated.
  • High-risk patients faced significant morbidity and mortality, necessitating long-term follow-up for graft patency and survival assessment.
