Thirty patients in whom all aorta-coronary artery vein grafts became occluded within one year of operation, as demonstrated by cardiac catheterization, were evaluated for hypercoagulability. A total of 59 grafts were constructed in these patients. At operation, blood flows of 35 to 90 c.c. per minute were measured through the grafts. In 23 of the 30… (More)
Following electrophysiological study and intraoperative mapping, an 11-year-old girl with incessant automatic atrial tachycardia and clinical features of congestive cardiomyopathy underwent successful surgical excision of an ectopic focus localized to the right atrial appendage. Dramatic clinical improvement resulted, and echocardiographic indices of left… (More)
During a 4-year period, 286 patients underwent coronary artery bypass grafting (CABG) following percutaneous transluminal coronary angioplasty (PTCA). Seventy-three patients had single-vessel and 213 (74.5%) had multivessel coronary artery disease. Twenty-nine patients underwent PTCA because of an evolving acute myocardial infarction (MI). Forty-two… (More)
Severe focal right coronary artery spasm, demonstrated on angiography, occurred in a 12 year old girl undergoing attempted electrode catheter ablation of a right atrial-right ventricular free wall accessory pathway.
One hundred patients were screened for hypercoagulability preoperatively and on the third, seventh, tenth, fourteenth, and twenty-first days postoperatively. Patients found to have hypercoagulability were treated with heparin, aspirin, and Coumadin. When the abnormality was present preoperatively, treatment was continued for the duration of the patient's… (More)
A 48-year-old man developed a plasmacytoma in the subcutaneous pocket of a titanium covered pulse generator that had been inserted sixteen months previously. The tumor represented a cutaneous manifestation of myelomatosis. The presence of a pacemaker may affect the detection and treatment of tumors arising in the region of pulse generator pockets. Possible… (More)
