Marsupialization of intramyocardial left anterior descending artery: a novel approach for easy access during revascularization.
The left anterior descending (LAD) artery is the most important vessel bypassed during coronary revascularization procedures. This artery usually runs a superficial course, making it easy for localization and grafting. However, many times it takes a course deep in the myocardium or is embedded in thick epicardial fat, which results in technical challenges to the surgeon for localization and grafting. So far, many techniques are described for overcoming these problems, but all require cardiopulmonary bypass (CPB), and in fact, intramyocardial LAD is considered a relative contraindication for off-pump coronary artery bypass grafting (OPCAB). In the present era of enhanced interest in OPCAB, these techniques are not as helpful as they are for conventional CABG with CPB. Here, we describe a novel approach of marsupialization of the LAD for revascularization of intramyocardial LAD that is useful for off-pump as well as conventional revascularization procedures and makes grafting simple and reproducible.
