[Coronary angioplasty using last generation materials. Immediate results].
OBJECTIVE
To present immediate results of percutaneous transluminal coronary angioplasty (PTCA) with the use of last generation catheter devices.


METHODS
74 patients underwent PTCA mean age 55 years the majority of them with disease of one vessel (92%) and good left ventricular function (88%). There was a total of 80 lesions treated, 26 type A and 54 type B according to the Task Force for Coronary Angioplasty of the American College of Cardiology--American Heart Association Classification. Results were analysed by separate observers: one clinical cardiologist (C), one cardiovascular surgeon (S) and two hemodynamicists (H1, H2).


RESULTS
A significant fail in the degree of coronary obstruction was demonstrated post PTCA in the opinion of the observers: C = 83 +/- 10.7/9.0 +/- 14; S = 86 +/- 13.0/9.3 +/- 11; H1 = 88.6 +/- 7.0/8.5 +/- 12; H2 = 88.5 +/- 8.0/8.3 +/- 12 (P less than 0.001). Angiographic success was attained in 94.6% of the cases and the complication rate was low 2.7%.


CONCLUSIONS
The high primary success and the low complication rates seen in this series can be attributed to the careful selection of cases and advanced performance of the catheterization devices that were used.
