Abstract:
BACKGROUND: Total obstruction of the left main coronary artery is a common cause of sudden death but is rarely seen in patients who survive to undergo diagnostic evaluation or treatment. METHODS: During twenty six-year period, we encountered 5 patients with chronic total obstruction of the left main coronary artery out of about 4,000 patients who underwent coronary angiography. RESULTS: All patients have undergone coronary bypass surgery. These patients present with increasingly severe angina. A right dominat coronary anatomy is always found, usually with well-developed right-to-left collaterals. Left ventricular function was severely impaired in two patients out of five patients. CONCLUSIONS: The results of surgical revascularization in our patients and others described in the literature can support the safety and efficacy of this approach.
