[Percutaneous transluminal coronary angioplasty. The experience of the Hospital de Especialidades of the La Raza Medical Center, IMSS].
We analyzed the initial results of the PTCA program at the Hospital de Especialidades CMR, IMSS. During the last year we studied 33 patients in whom we performed 35 PTCA procedures with total of 45 lesions. The age of the patients varied from 27 to 75 years of age (average 57 year +/- 10.9). Among them, 84.8% were males and 15.2% females. In 54.5% of the patients, stable angina was present, whereas in 45.5% unstable angina was observed. Multivessel disease was detected in 39.4% of the cases. In 17.8% the coronary lesions were type "A", in 77.8% type "B" and in 4.4% type C. The most frequent lesions were present at the left anterior descending artery in 46.6%, right coronary artery in 40% and circumflex in 13.4%. The global procedural success was 88.5% (32/35 procedure) whereas the procedural success by isolated lesion was 88.8% (40/45 lesions). The average artery stenosis was decreased from 85 +/- 10.4% to 23 +/- 16%. A procedural failure occurred in 4 instances (11.4%), among them, 2 (5.71%) without complications and 2 more, associated to acute myocardial infarction. In the present study there were no emergency operation neither deaths.


CONCLUSIONS
Although the number of PTCA performed in our hospital is limited, we consider that the initial results are good, with a success rate of 88.5% with a minimal complications.
