1/306. Treatment of a large congenital coronary fistula with coil embolization.

    A 77-year-old woman suffering from progressive dyspnea and chest pain for 2 1/2 years was admitted to hospital. There were no ECG changes at exercise test and a dobutamine stress echocardiography was normal. At catheterization, right-sided pressures were within normal limits. coronary angiography revealed a congenital coronary fistula, 3-4 mm in diameter, from the left anterior descending artery to the proximal pulmonary artery. There was no significant rise in blood oxygen saturation in the pulmonary artery. Transcatheter coil embolization was performed in the distal part of the tortuous fistula. Flow ceased within minutes, demonstrating the feasibility and efficacy of this technique for treating large fistulas.

2/306. cesarean section in a mother with uncorrected congenital coronary to pulmonary artery fistula.

    PURPOSE: We report a case of a 33 yr old woman with pulmonary hypertension secondary to uncorrected right coronary artery to pulmonary artery fistula who underwent two successful operative deliveries under general anesthesia. CLINICAL FEATURES: This woman underwent an emergency Caesarean section at 32 wk gestation because she presented in NYHA Class IV, heart failure and premature labour. She did not have antenatal follow-up. For her second pregnancy, she was managed from the first trimester of pregnancy by the cardiologist, obstetrician and anesthesiologist. She received oral furosemide and digoxin from eight weeks gestation. pregnancy was managed to term before she progressed to NYHA Class IV and cardiac failure at 37 wk gestation. She had a Caesarean section under general anesthesia. She received rapid sequence induction of anesthesia and tracheal intubation with 0.1 mg x kg(-1) etomidate, 2 mg x kg(-1) succinylcholine and maintenance with nitrous oxide 50% in oxygen, isoflurane 1% and 0.1 mg x kg(-1) vecuronium. fentanyl, 2 microg x kg(-1) helped to obtund the hypertensive response to intubation. analgesia was provided with 1 mg x kg(-1) morphine. Glyceryl trinitrate infusion, 10-30 microg x min(-1) was used in addition to the anti-heart failure therapy. End-tidal capnography, electrocardiogram, pulse oximetry, continuous arterial blood pressure and pulmonary arterial catheter provided hemodynamic monitoring. The lungs were mechanically ventilated for 24 hr postoperatively. She received anti-heart failure therapy which she continued after discharge. She was NYHA class II upon discharge. She defaulted from further follow-up. CONCLUSION: Although the literature advocates, in this situation, controlled vaginal delivery utilising epidural analgesia, we describe the successful outcome for operative delivery under general anesthesia in a patient with secondary pulmonary hypertension and heart failure.

3/306. Catheter-based techniques for closure of coronary fistulae.

    This study details different methodologies of percutaneous closure of arteriosystemic and arteriovenous coronary fistula. Seven patients underwent transcatheter intervention of 10 fistulas, with 7 fistulas successfully closed: 6 with embolic coil devices and 1 with a covered stent obstructing the fistula ostium. The major complication encountered was one death as a result of device recoil into a major epicardial vessel. Percutaneous transcatheter closure of coronary fistulas appears to be simple, facile, and effective. However, device recoil into an undesired arterial segment, while irritating in a noncoronary arterial tree, may be catastrophic when occurring in an epicardial coronary artery.

4/306. Successful closure of coronary-bronchial artery fistula with vein graft-coated stent.

    A coronary-bronchial fistula and aneurysmal dilatation of the proximal part of the fistula was successfully closed using an autologous vein graft-coated stent (Palmaz-Schatz stent). This is the first report that demonstrates the feasibility of the vein-coated stent for the treatment of congenital disease.

5/306. Multiple spontaneously occurring coronary artery-left ventricular communications: a case report.

    A search of the literature revealed that spontaneous coronary artery-left ventricular communications have only rarely been reported. These fistulae are frequently associated with angina pectoris which has been attributed to a ventricular steal phenomenon. The patient described herein presented with angina pectoris and was found to have multiple coronary arterioventricular communications without significant coronary atherosclerosis.

7/306. Transcatheter closure of a large coronary artery fistula with the Amplatzer duct occluder.

    We report the successful percutaneous closure of a large coronary artery fistula from the obtuse marginal artery to the right ventricle in an 8-month-old boy using the Amplatzer duct occluder. The device was positioned and deployed via the venous system, using a guidewire that had been advanced via the aorta, coronary artery, and fistula to the venous circulation. Cathet. Cardiovasc. Intervent. 48:188-190, 1999.

8/306. Left coronary artery-left ventricular fistula with acute myocardial infarction, representing the coronary steal phenomenon: a case report.

    A 59-year-old man presented with a left anterior descending coronary artery to left ventricular fistula manifesting as myocardial infarction, representing the coronary steal phenomenon. electrocardiography showed poor R progression in leads V1 through V3. The biochemical markers of myocardial injury were elevated. creatine kinase level was 509 IU/l, creatine kinase MB isoenzyme (CK-MB)47 IU/l, cardiac troponin t 0.62 ng/ml, myosin light chain 6.1 ng/ml, and myoglobin 142 ng/ml. thallium-201 myocardial perfusion imaging with dobutamine stress showed a dobutamine-induced perfusion deficit of the anteroseptal wall of the left ventricle with 0.1 mV ST-segment depression in II, III, aVF, V5, and V6. The mean left anterior descending blood flow measured with the Doppler guidewire was increased from 211 to 378 ml/min. Selective coronary arteriography showed dominant left coronary artery with the contrast medium streaming into the left ventricle via a maze of fine vessels from the distal left anterior descending coronary artery. No critical stenosis of the left anterior descending coronary artery was observed. Administration of acetylcholine 100 micrograms into the left coronary artery did not induce vasoconstriction of that artery. The fistula terminating in the left ventricle was ligated surgically and the patient became free of chest pain. thallium-201 myocardial perfusion imaging with dobutamine stress revealed no perfusion deficit of the anteroseptal wall of the left ventricle. The presence of coronary steal phenomenon was detected by dobutamine stress myocardial imaging.

9/306. Coronary arteriovenous fistula with a giant aneurysm: role of transesophageal echocardiography.

    Congenital coronary arteriovenous fistulas are rare anomalies. patients may present with congestive heart failure, ischemic chest pain, or endocarditis. In this case, transesophageal echocardiography provided valuable additional information to that obtained from cardiac catheterization, which was essential for the diagnosis and planning of surgical correction.

10/306. Diagnosis of a left coronary artery to right ventricular fistula with progression to spontaneous closure.

    Coronary artery fistulas in structurally normal hearts are rare. The natural history of these lesions depends on their size and can cause congestive heart failure, infective endocarditis, ischemia, or accelerated atherosclerosis. These fistulas are usually closed either in the catheterization laboratory or surgically. This case demonstrates the prenatal diagnosis of a left coronary to right ventricular fistula and documents its natural history to spontaneous closure by 1 year of age. This may help confirm the rationale of observation rather than closure of small fistulas in selected cases of patients without symptoms.
