Coronary angioplasty with second generation Monorail catheters.

摘要: The Monorail system (Schneider) consists of a balloon catheter in which the guidewire passes through itself, exits proximal to balloon, and runs alongside its small shaft (3 French) length guiding catheter. It offers distinct advantages over conventional systems coronary angioplasty. facilitates contrast injections permits rapid exchanges. This was used for angioplasty 273 unselected consecutive patients (age 59 +/- 10, mean 35 73 years). There were 216 (84%) undergoing single-vessel 57 (16%) with multi-vessel A total 335 stenoses dilated, included occlusions. size ranged from 2.0 4.25 mm (3.0 0.5 mm) severity stenosis 85 11%. Technical success defined as residual less than 50% determined angiographically. Clinical technical success, absence major inhospital complication myocardial infarction, lack need arterial bypass surgery, survival. technically successful 294/300 stenotic lesions (98%). clinically 281 (94%). Of occlusions, obtained 25 (71%). cases 26 21%. also 5 more 90% whom failed. complications acute occlusion causing infarction 13 (5%), emergency surgery 1 patient (0.4%), death 4 (1.5%).(ABSTRACT TRUNCATED AT 250 WORDS)
