1/147. Therapeutic embolization for unusual latrogenic complications related to coronary revascularization.

    Percutaneous therapeutic embolization may be an effective strategy to manage distal coronary perforations or inadvertent iatrogenic coronary arteriovenous fistula complicating revascularization procedures. We present two cases in which embolization techniques were used to manage these patients and avoid the need for surgical intervention.

2/147. exercise-induced ventricular tachycardia associated with coronary arteriovenous fistula and correction by transcatheter coil embolization.

    exercise-induced ventricular tachycardia is a well-described arrhythmia most commonly associated with atherosclerotic coronary artery disease. The case reported here presents its association with a coronary arteriovenous fistula, which has not been previously reported in the literature.

3/147. Treatment of a coronary artery to superior vena cava fistula resulting from early closure of a Possis Perma-Flow graft.

    The Perma-Flow graft used in bypass surgery achieves more complete revascularization when paucity of native conduits exists. We report a coronary artery to superior vena cava fistula as a complication of this graft, leading to severe right heart failure. The fistula was successfully occluded percutaneously, improving the patient's clinical situation.

4/147. Vertebral arteriovenous fistula as a result of Swan-Ganz catheter insertion: surgical correction in a symptomatic patient.

    A case of a vertebral arteriovenous fistula is reported after being caused by insertion of a Swan-Ganz catheter into the vertebral artery prior to cardiac surgery. The patient's clinical symptoms which precipitated re-admission consisted of multiple episodes of diaphoresis and dizziness. A right carotid bruit was detected in the neck. Four vessel cerebral arteriograms could not accurately identify the origin of the fistula. The proximal carotid artery was considered by several radiologists to be the arterial source of the fistula. During the surgical procedure, a tortuous right vertebral artery was found to be the source of the fistula. Surgical correction of the fistula was successful with preservation of the vertebral artery. Recommendations from a review of the literature are made for the current treatment of this rare complication from an insertion of a Swan-Ganz catheter.

5/147. A large coronary artery saphenous vein bypass graft aneurysm with a fistula: case report and review of the literature.

    We describe a patient who developed a large aneurysm of saphenous vein graft to the right coronary artery with a fistulous communication to the right atrium. The presence of a fistulous communication of a saphenous vein graft aneurysm after coronary bypass surgery to one of the heart chambers is extremely rare. The diagnosis was made by coronary angiography and confirmed by CT and MRI. At surgery the aneurysm was ligated and excised. The fistula to the right atrium was closed. Repeat coronary artery bypass surgery with aortic valve replacement was performed at the same time without complications. Cathet. Cardiovasc. Intervent. 48:214-216, 1999.

6/147. Coronary artery aneurysm associated with fistula in adults: collective review and a case report.

    Coronary artery fistulae (CAF) are infrequent congenital anomalies. The combination of coronary artery aneurysms and coronary artery fistulae (coronary artery aneurysm associated with fistula, CAAAF) is extremely rare, and only 50 cases, including the current case, have been reported. Coronary artery fistulae may result in coronary ischemia, congestive heart failure, and endocarditis. Complications of coronary artery aneurysms include thrombosis, distal emboli, and aneurysm rupture. Aneurysm repair, fistulous closure and/or coronary artery bypass grafts are definite treatments for CAAAF. We present here a 72-year-old female with CAAAF. Furthermore, all reported CAAAF cases are reviewed.

7/147. Surgical treatment of a coronary artery fistula with concomitant saccular coronary artery aneurysm: a case report.

    An extremely rare case of a coronary artery fistula with a concomitant saccular aneurysm is presented. A 65-year-old woman, who had a history of chest bruising 5 years earlier, suffered from chest pain, which was diagnosed as being due to left coronary artery-pulmonary artery fistulae concomitant with a giant saccular coronary artery aneurysm. Suture closure of the afferent coronary artery to the aneurysm, aneurysmorrhaphy, and transpulmonary closure of coronary artery-pulmonary artery fistulae were performed. The postoperative course was uneventful and the patient was well at 3 months after the operation. Because the risk of surgery appears to be less than the potential development of fatal complications, it is recommended for the treatment of coronary artery fistula with a concomitant saccular aneurysm.

8/147. Intraoperative localisation and management of coronary artery fistula using transesophageal echocardiography.

    Coronary artery fistula is a rare congenital malformation that can be complicated by intracardiac shunts, endocarditis, myocardial infarction, coronary aneurysm and sudden death. Clinical symptomatology depends upon the underlying anatomy and the size of the fistulous connection between the left or right side of the heart. We report the successful management of a giant right coronary artery with fistulization into the right atrium. Intraoperative transesophageal echocardiography with colour flow Doppler was used for precise location of the fistulous communication, selective demonstration of vessels feeding the fistula and documentation of abolition of fistulous flow all without the need for cardiopulmonary bypass. Furthermore the effect of shunt occlusion on regional wall motion was documented which facilitated the successful ligation of the fistula.

9/147. Results of saphenous vein graft stent implantation: single center results from use of oversized balloon catheters.

    The results and complications of a single-center experience of stent implantation in old saphenous vein grafts (SVGs) need to be defined. The authors studied their initial consecutive 92 patients (125 stents, 1.4 stents/per patient) with a mean age of 67 /-9 years. The patients' mean saphenous vein graft (SVG) age was 10 /-4 years, and the mean left ventricular ejection fraction was 46% /-15. Patient population included unstable angina (65%), stable angina (10%), myocardial infarction (21%), and silent ischemia (4%). The authors implanted 122 Palmaz-Schatz/biliary and three Gianturco-Roubin stents. They aimed at a balloon-artery ratio of 1.1/1.0. Procedural success, defined as stent deployment with <50% stenosis without death/Q-wave myocardial infarction/coronary artery bypass grafting (MI/CABG) was 95%. The mean luminal diameter (MLD) increased from 0.6 /-0.5 to 3.3 /-0.8 mm (p<0.001) and mean SVG stenosis diameter was decreased from 80% /-14 to -10% /-11 (p<0.001). Angiographic SVG lesions exhibited thrombus (17%), ulceration (38%), and plaque rupture (28%). Sixty-two patients were treated with warfarin and aspirin and 30 with ticlid and aspirin. Complications included death in three patients (3.3%) who sustained subacute stent thrombosis, and two of three had Q-wave MI. Distal embolization occurred in seven patients (8%); six of seven sustained a non Q-wave acute myocardial infarction (AMI); and one of seven a Q-wave MI. Eight (9%) patients had major groin hematoma, two had pseudoaneurysm (2.2%), one had arteriovenous (A-V) fistula (1.1%), two had vascular surgery (2.2%), nine had blood transfusion (9.8%), and three had stent migration (3.3%). Single-center experience with stents in SVGs indicates a highly successful procedural and angiographic immediate result. However, it was complicated by significant risk of non Q-wave MI due to distal coronary embolization which may affect prognosis.

10/147. Transthoracic fistula with erosion of the ascending aorta along an IMA-protecting graft.

    Internal mammary artery (IMA) graft protection with nonbiodegradable material, such as polytetrafluorethylene (PTFE), is recognized as an effective means for preventing overexuberant adhesion development as well as injury of retrosternally crossing arterial grafts in the event of resternotomy and should enable better identification of the IMA graft. It is still uncertain whether the use of PTFE material is suitable for diabetic patients with complete arterial revascularization due to potential infectious complications. We report on a young diabetic patient after arterial T-grafting due to severe coronary disease and readmission with wound infection and retrosternal fistula formation 8 months after operation.
