BRIEF HISTORY: The patient is a 44-year-old cigarette smoker with a markedly positive family history of coronary artery disease who has an electrocardiogram showing an old anterior septal myocardial infarction. Nuclear study showed a fixed anterior defect. He has had episodes of chest pain and coronary angiography has been recommended. DESCRIPTION OF THE PROCEDURE: One percent lidocaine was infiltrated over the right femoral artery. A 6-French sheath was placed in the right femoral artery. Diagnostic coronary angiography was performed with a 6-French JL-4 and 6-French JR-4 diagnostic catheters. Following coronary angiography, a 6-French pigtail catheter was placed in the left ventricle where left ventriculography was performed with 36 cc of contrast injected at 12 cc per second. At the conclusion of the procedure, the catheter and sheath were removed and Angio-Seal plug was deployed. TECHNICAL FACTORS: Medications: Fentanyl 100 mcg and Versed 2 mg. Contrast: Isovue 130 cc. Fluoroscopy time: 2 minutes. HEMODYNAMICS: Opening aortic pressure 103/58. Following coronary angiography, the left ventricular pressure was 107/12. There was no aortic stenosis on left heart pullback. CORONARY ANGIOGRAPHY: There was no significant obstructive coronary artery disease in this right dominant system. There is a 10% to 20% stenosis in the distal left main. The left circumflex artery is a moderate-sized vessel filling a large first obtuse marginal and diminutive second obtuse marginal and there is no significant disease. The left anterior descending coronary artery is a large vessel which extends to the apex. It fills several small diagonal branches. There are no significant stenoses. There is a large ramus intermedius which fills the lateral wall. It, too, has no significant disease. The right coronary artery is a large dominant vessel filling a moderate-sixed posterior descending artery and two larger posterolateral branches. There are no significant obstructions in the right coronary artery. LEFT VENTRICULOGRAPHY: The left ventricular systolic function is noimal. There are no regional wall motion abnormalities. There is no mitral regurgitation. DIAGNOSTIC IMPRESSION: 1. There is no significant obstructive coronary artery disease in this right dominant system. There Rules / Statistical Engine is a plaque in the distal left main, but there is no significant obstruction. 2. Left ventricular systolic function is normal. There is no evidence of previous anterior wall myocardial infarction. PLAN: I do not have a definite explanation f or the patient's abnormal electrocardiogram or abnormal nuclear study. Coronary spasm remains in the differential diagnosis and we have encouraged him to completely discontinue smoking, which he has accomplished. He certainly can take nitroglycerin on an as-needed basis in the future. I would continue aspirin indefinitely.
