Noncoronary collateral distribution in coronary artery disease
GN Olinger, LI Bonchek and DM Geiss
Noncoronary collateral flow is a potential hazard when cold cardioplegia is
used for myocardial protection. In this study, noncoronary collateral flow
was observed during coronary revascularization in 58 patients. It was
distributed significantly (p less than 0.005) toward arteries demonstrating
intercoronary collateral flow angiographically - 1.0 of 35 with and 12 of
121 without. Preponderance of coronary collateral flow in hearts with more
extensive disease may complicate cardioplegic myocardial protection for
such patients.
