Implication

Hypothesis-generating for complex arterial conduits in multivessel disease; prospective trials required before practice change.

Key Points

To assess the clinical feasibility, safety, and angiographic patency of utilizing composite preformed arterial conduits for extensive myocardial revascularization.
Analyzed an observational cohort of N=130 patients (mean age 60.1 years; 121 males; 126 with double- or triple-vessel disease) undergoing coronary revascularization between October 1991 and May 1993.
Constructed 136 complex branched or lengthened conduits using 360 arterial grafts, primarily anastomosing free grafts to internal mammary arteries.
Evaluated early angiographic patency (days 7 to 15 postoperatively), late angiographic patency (mean interval 9.5 months), and clinical outcomes at a mean follow-up of 7.2 months.
Operative mortality was 0%, with an overall mortality rate of 1.5% (2/130), and no patients required inotropic or mechanical circulatory support.
Early angiography showed 100% conduit patency, while late angiography revealed patency rates ranging from 94.1% for radial arteries to 100% for left internal mammary and right gastroepiploic arteries.
At a mean follow-up of 7.2 months (range 1 to 15 months), all surviving patients remained alive without recurrence of angina symptoms.

Structured PICO

Does myocardial revascularization using complex preformed arterial conduits provide good graft patency and clinical outcomes in patients with multivessel disease?

Population

130 patients undergoing myocardial revascularization, mean age 60.1 years, 121 male. 126 patients had double- or triple-vessel disease, mean ejection fraction 0.53.

Intervention

Myocardial revascularization using complex preformed arterial conduits (branched, lengthened, or both)

Outcome

Operative mortality, overall mortality, early and late angiographic patency, and symptom recurrencehard clinical

Myocardial revascularization using complex preformed arterial conduits is safe and provides excellent early and late graft patency.
