Beating heart revascularization using only bilateral internal thoracic arteries for XXXX : early angiographic findings.

@entity1 @entity66 @entity6 @entity254 @entity583 @entity850
BACKGROUND: Early postoperative coronary angiography was performed to establish the feasibility of treating @entity1 with @entity66 by performing completely arterial revascularization on the beating heart using only bilateral internal thoracic arteries (ITAs). METHODS: Between March 2001 and February 2003, 113 @entity1 with @entity66 (age, 62.0 +/- 8.6 years) underwent beating heart revascularization using only the bilateral ITAs. Left ventricular ejection fractions ranged from 23% to 78% (mean, 51.3% +/- 15.1%). The incidence of @entity6 was 46%. Early postoperative coronary artery angiographic follow-up was performed since May 2002 in the last 59 sequential @entity1 . RESULTS: There were no operative deaths. Perioperative @entity583 occurred in only 1 @entity1 each. The mean number of distal anastomoses was 3.9 +/- 0.7 per @entity1 . The patency rates were 100% for the left ITA and 98.1% for the right. Competitive flow patterns were present in 25 distal @entity254 sites (10.5%). A multivariate analysis showed that the degree of @entity850 (<75%), the extent of focal @entity850 of the native coronary artery, and the intraoperative transit-time flow rate (<10 mL/min) were the statistically significant risk factors for competitive flow. CONCLUSION: This surgical strategy is feasible, is safe, and yields good early angiographic outcomes, even following beating heart revascularization. However, in less significant lesions competitive flow patterns were relatively prevalent, so this technique might be reserved until it is proven to provide good long-term patency and function.
