Coronary artery anomalies in 126,595 patients undergoing coronary arteriography.

Abstract: Coronary artery anomalies were found in 1,686 patients (13% incidence) undergoing coronary arteriography at the Cleveland Clinic Foundation from 1960 to 1988 Of the 1,686 patients, 1,461 (87%) had anomalies of origin and distribution, and 225 (13%) had coronary artery fistulae Most coronary anomalies did not result in signs, symptoms, or complications, and usually were discovered as incidental findings at the time of catheterization Eighty-one percent were “benign” anomalies: (1) separate origin of the left anerior descending and circumflex from the left sinus of Valsalva; (2) ectopic origin of the circumflex from the right sinus of Valsalva; (3) ectopic coronary origin from the posterior sinus of Valsalva; (4) anomalous coronary origin from the ascending aorta; (5) absent circumflex; (6) intercoronary communications; and (7) small coronary artery fistulae Other anomalies may be associated with potentially serious sequelae such as angina pectoris, myocardial infarction, syncope, cardiac arrhythmias, congestive heart failure, or sudden death Potentially serious anomalies include: (1) ectopic coronary origin from the pulmonary artery; (2) ectopic coronary origin from the opposite aortic sinus; (3) single coronary artery; and (4) large coronary fistulae Coronary artery anomalies require accurate recognition, and at times, surgical correction

Percutaneous radial artery approach for coronary angiography.

Abstract: Percutaneous entry into the distal radial artery and selective coronarography using a French 5 sheath and preshaded catheters were attempted in 100 patients with a normal Allen test. Cannulation of the radial artery was not possible in ten patients, and selective catheterization of the coronary arteries was unsuccessful in two. Manipulation of catheters presented no problem, and arterial spasm was rarely observed, only before the use of a 23-cm-long sheath. Only two complications without symptoms were observed: arterial dissection of the brachial artery in one patient and occlusion of the radial artery in another. With experience, this approach may become as effective and possibly safer than the transbrachial entry.

Percutaneous transradial artery approach for coronary stent implantation

Abstract: A new approach for implantation of Palmaz Schatz coronary stents is reported. We describe the technique and rationale of coronary stenting with miniaturized angioplasty equipment via the radial artery. This technique is illustrated in three patients. One patient underwent Palmaz Schatz stent implantation for a saphenous vene coronary bypass graft stenosis, the second patient for a restenosis in the anterior descending coronary artery after atherectomy, and the third patient for a second restenosis after balloon angioplasty in the circumflex coronary artery.

Transcatheter closure of secundum atrial septal defects using the new self‐centering amplatzer septal occluder: Initial human experience

Abstract: Transcatheter closure of secundum atrial septal defect (ASD) using clamshell or buttoned devices is accompanied by a high incidence of residual shunt. Recently, a new self-centering device, the Amplatzer septal occluder (ASO), has been evaluated in an animal model with very good results. Therefore, our purpose is to report on our initial clinical experience with this device. Thirty patients underwent an attempt at catheter closure of their ASDs at a median age of 6.1 yr (range, 2.9-62.4 yr) and median weight of 22 kg (range, 13-69 kg) using the ASO. The median ASD diameter measured by transesophageal echocardiography (TEE) was 12.5 mm (range, 5-21 mm), and the median ASD balloon stretched diameter was 14 mm (range, 7-19 mm). All patients had right atrial and ventricular volume overload with a mean +/- SD Qp/Qs of 2.3 +/- 0.6. A 7F catheter was used for delivery of the device in all patients. The device was placed correctly in all patients. There was immediate and complete closure (C) in 17/30 patients, 10 patients had trivial residual shunt (TS), and 3 had moderate residual shunt (MS). The median fluoroscopy time was 15 min (range, 8-35 min), and the median total procedure time was 92.5 min (range, 40-135 min). There was no episode of device embolization or any other complication. Follow-up was performed using transthoracic echocardiography (TTE) 1 day, 1 mo, 3 mo, and yearly thereafter. At 1 day, there was C of the ASD in 24/30 patients, 3 had TS, 1 had small shunt (SS), and 2 had MS. At a median follow-up interval of 6 mo, there have been no episodes of endocarditis, thromboembolism, or wire fracture. We conclude that the use of the new ASO is safe and effective in complete closure of secundum ASDs up to a diameter of 21 mm in the majority of patients. Further clinical trials are underway.

Cardiac catheterization 1990: a report of the Registry of the Society for Cardiac Angiography and Interventions (SCA&I).

Abstract: This report presents the first year's experience of a totally computerized cardiac catheterization laboratory reporting system, including the results and complications of invasive and interventional procedures. Sixty-three laboratories reported a total of 71,916 patients studied between January 1 through December 31, 1990. Two previous registry reports have been published. Compared with data acquired by previous methods, in spite of an older and sicker population, the mortality for diagnostic procedures has remained remarkably constant (0.11%). The computerized format facilitates data collection and analysis, helps resolve new issues as they arise and serves as a method of monitoring quality of laboratories and individuals.
