Comparison of clinical and laboratory findings between patients with diffuse three-vessel coronary artery spasm and other types of coronary artery spasm.
Our purpose was to compare patients with diffuse three-vessel coronary artery spasm and other types of coronary artery spasm without significant organic stenosis, and to elucidate clinical characteristics and risk factors. Patients were divided into two groups: group I consisted of 26 patients showing other types of coronary artery spasm; group II consisted of 5 patients with diffuse three-vessel coronary artery spasm. The mean age of patients in groups I and II was 52 and 50 years, respectively. ⋯ First, we conclude, diffuse three-vessel coronary artery spasm mostly occurs spontaneously. Second, we emphasize that diffuse three-vessel coronary artery spasm must be considered when 12-lead ECG shows no important ST segment changes with episodes of angina. Third, it is not easy to distinguish diffuse three-vessel coronary artery spasm from other types of coronary artery spasm on the basis of history, laboratory data, or electrocardiographic findings, including exercise tests.

Case ReportsSustained consciousness during ventricular fibrillation: case report of cough cardiopulmonary resuscitation.
A 54-year-old male developed ventricular fibrillation during right coronary angiography. Cough cardiopulmonary resuscitation was performed for 30 sec allowing the patient to remain alert and hemodynamically stable. Cough cardiopulmonary resuscitation is a simple, often overlooked technique that can be utilized during resuscitation in the cardiac catheterization laboratory.

Case ReportsPercutaneous retrieval of a broken umbilical catheter from left atrium in a premature newborn.
A 30-week gestational age baby boy weighing 1,117 g born with cesarian section had a broken umbilical vein catheter lodged in the left superior pulmonary vein. We successfully retrieved the foreign body by percutaneous approach using a pigtail catheter and a snare wire under portable fluoroscopy.

Effectiveness of balloon valvuloplasty in the young adult with congenital aortic stenosis.
The objective of this study was to assess the effectiveness of balloon valvuloplasty in the young adult with congenital aortic stenosis and to compare its effectiveness with children. Percutaneous balloon valvuloplasty is effective in children with congenital aortic stenosis, but not in adults with acquired calcific aortic stenosis. Because effectiveness of balloon valvuloplasty in young adults with congenital aortic stenosis is not well defined, we evaluated the outcome in 15 patients aged 16-24 years (18 +/- 0.6; mean +/- SEM) who underwent balloon valvuloplasty from 1985 to 1993. ⋯ Balloon valvuloplasty was as effective in these young adults as in 70 children (age 6 +/- 0.7 years) with congenital aortic stenosis (peak systolic gradient pre- 79 +/- 3 mm Hg versus post- 34 +/- 2 mg Hg; at 1-2 years follow-up 34 +/- 4 mm Hg). Balloon valvuloplasty provides effective treatment in most young adults with congenital aortic stenosis, without early restenosis. Balloon valvuloplasty is as effective in young adults as in children, where it is currently the treatment of choice.

Review Case ReportsCongenital clavicular pseudoarthrosis associated with vascular thoracic outlet syndrome: case presentation and review of the literature.
Thoracic outlet syndrome (TOS) associated with congenital clavicular pseudoarthrosis is rare in adults and often misdiagnosed. In this case report, we describe an adult female who was found to have thrombosis of the subclavian and axillary arteries with embolization documented by invasive angiography. This unusual vascular manifestation of TOS should remind physicians that anatomic derangements may predispose to upper extremity ischemia.
