NAME OF PROCEDURE: , Left heart catheterization with ventriculography, selective coronary angiography.,INDICATIONS: , Acute coronary syndrome.,TECHNIQUE OF PROCEDURE: , Standard Judkins, right groin.  Catheters used were a 6 French pigtail, 6 French JL4, 6 French JR4.  ,ANTICOAGULATION:  ,The patient was on heparin at the time.,COMPLICATIONS: , None.,I reviewed with the patient the pros, cons, alternatives, risks of catheterization and sedation including myocardial infarction, stroke, death, damage to nerve, artery or vein in the leg, perforation of a cardiac chamber, dissection of an artery requiring countershock, infection, bleeding, ATN allergy, need for cardiac surgery.  All questions were answered, and the patient desired to proceed.,HEMODYNAMIC DATA:  ,Aortic pressure was in the physiologic range.  No significant gradient across the aortic valve.,ANGIOGRAPHIC DATA,1. Ventriculogram:  The left ventricle is of normal size and shape, normal wall motion, normal ejection fraction.,2. Right coronary artery:  Dominant.  There was insignificant disease in the system.,3. Left coronary:  Left main, left anterior descending and circumflex systems showed no significant disease.,CONCLUSIONS,1. Normal left ventricular systolic function.,2. Insignificant coronary disease.,PLAN: , Based upon this study, medical therapy is warranted.  Six-French Angio-Seal was used in the groin.surgery, standard judkins, french pigtail, selective coronary angiography, heart catheterization, ventriculography, catheterization, angiography,
