Abstract
The short- and long-term outcome of patients within the NHLBI PTCA Registry who underwent
repeat PTCA for coronary restenosis were analyzed. Of 1,880 patients in whom an initial
PTCA was successful, 203 had a repeat PTCA attempted after restenosis developed. Repeat
PTCA was usually performed within 6 months of the first procedure. The success rate
of repeat PTCA was 85.2%. As a direct result of repeat PTCA, 1.5% of patients had
an MI and 2% required emergency CABG. No patien died as a result of the attempted
second procedure. One to 3 years of follow-up information was available in 94% of
eligible patients. Most patients (75,9%) did not have a subsequent (third) PTCA, CABG
or an MI. The late mortality rate was 0.8%. Angiographic follow-up information was
available in 62 patients. Sustained enhancement of the diameter of the redilated lesion
was observed in 66%. Thus, repeat PTCA has a high success and a low complication rate.
Most patients did not have subsequent restenosis and are free of angina. Hence, repeat
PTCA should be recommended for patients who have restenosis and should be considered
as an integral component of PTCA therapy.
