Coronary angioplasty with monorail technique: experience in more than 2000 cases.
This article describes briefly the short- and long-term results of PTCA with monorail technique. From 1988 to 1992, 2183 out of a total of more than 4000 patients have been treated with this technique. From these patients, a total of 2693 vessels were dilated. Primary success was achieved in 93% of all attempted vessels, while the overall major complication rate of 3% was acceptable in this series. Although the primary success rates were comparable between patients with stable angina (n = 1288), unstable angina (n = 720), and acute myocardial infarction (n = 175), the major complication rate of 5.1% in patients with unstable angina was about twice of that in patients with stable angina. The long-term clinical follow-up of a mean of 22 months was favorable with low mortality (2%) and infarction (6%) rates. However, an additional revascularization procedure (repeat PTCA or bypass surgery) was necessary in 19% of the patients due to restenosis. In conclusion, PTCA using the monorail technique can be performed safely and effectively in patients with either stable angina, unstable angina, or acute myocardial infarction.
