Abstract

Percutaneous transluminal coronary angioplasty (POBA) of complex lesions is hindered by a lower success rate and a higher risk of complications. New devices are now available for treatment of this type of lesions (type B-C of the modified AHA/ACC classification). We present our experience in the treatment of calcified, ostial, angled and long coronary lesions by means of percutaneous transluminal coronary rotational ablation (PTCRA, Rotablator Heart Technology, Bellevue, Washington). From June 1991 to November 1995 we performed 71 procedures of rotational atherectomy on 72 lesions in 62 patients. Twenty-three patients presented stable angina, 30 patients unstable angina and 9 silent myocardial ischemia. Thirty-five patients had single, 16 double and 11 triple vessel coronary artery disease. Left ventricular mean ejection fraction was 58 +/- 8%. The lesions attempted were classified as type A in 2 cases, B1 in 23 cases, B2 in 31 cases and C in 16 cases according to the AHA/ACC modified classification. Calcifications detected at coronary angiography were present in 66 lesions; 53 lesions were longer than 10 mm; 12 were more than 45 degrees angulated; 9 were at a bifurcation site and 3 were ostial in location. The vessels treated ...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
