[Complete occlusion both left main coronary artery and right coronary artery]
Insights
This study reports successful coronary revascularization in a patient with complete left main and right coronary artery occlusion. The patient experienced significant relief from severe angina pectoris following the procedure.
Area of Science:
- Cardiology
- Cardiovascular Surgery
Background:
- Severe angina pectoris indicates significant coronary artery disease.
- Complete occlusion of the left main coronary artery (LMCA) and right coronary artery (RCA) presents a critical scenario.
Observation:
- A 67-year-old male patient presented with severe angina.
- Preoperative assessments revealed myocardial ischemia and extensive collateral circulation.
- Cardiac catheterization showed severe coronary sclerosis but preserved left ventricular function.
Findings:
- The patient underwent successful coronary revascularization with three saphenous vein grafts.
- Grafts were placed to the left anterior descending (LAD), left circumflex (LCX), and RCA.
- Postoperative follow-up at 6 months showed complete resolution of angina.
Implications:
- Coronary revascularization is effective for patients with LMCA and RCA occlusion.
- Collateral circulation may play a role in preserving ventricular function in severe coronary artery disease.
- Timely surgical intervention can significantly improve quality of life for patients with critical coronary stenosis.
Abstract:
A 67-year-old man, who had complete occlusion both of left main coronary artery (LMCA) and right coronary artery (RCA), underwent coronary revascularization. He had been suffering from severe angina pectoris preoperatively. Exercise electrocardiogram (single Master) showed myocardial ischemia. On cardiac catheterization, he showed extensive collaterals from right main coronary artery, and well-preserved left ventricular function. At operation, coronary arteries revealed severe sclerosis, especially in RCA, but there was no evidence of old myocardial infarction. Three saphenous vein grafts were bypassed to LAD, LCX, and RCA. Postoperatively, he remained free of angina pectoris at 6 months after uneventful surgery.
