067 Detection of the coronary restenosis after coronary angioplasty by myocardial perfusion imaging (spect), a prospective study

The angioplasty transluminale coronary (ATC), gesture of revascularisation which can be realized at the same time that the coronarography, can be enamelled by complication, the most frequent of which are the restenosis.The aim of our study is to specify, the contribution of the a myocardial perfusion imaging (SPECT) in the detection of the coronary resténose after a planed ATC.We report in this prospective study, the contribution of the SPECT imaging in the evaluation of the resténose after ATC. The gold standard being the coronarography. The study of the resténose is made by angiographique quantification at 6 months.It is about 126 patients, 115 men whose average age is 57,42 ± 8,53 years presenting a coronary monotronculaire lesion. 24% of the patients are diabetics and 63% of the men are smoking.On the coronarographic side, we undertook a dilation on 129 lesion. Sixty seven percent of the lesion sits on the anterior interventriculaire (IVA), 21% on right coronary and 12% on circumflex. Sixty two percent lesion are of type ≥ B2. In 19% of the cases, the diameter is less than 2,5mm. Its length is > 15mm in 56% of the cases. The used stents is in naked metal.The coronarographique control in 6 months interested 118 patients. The rate of restenosis angiographic was estimated at 12%. The performance of the SPECT myocardial imaging correlated at the coronarography allowed to detect the restenosis with a 88% sensibility, a 98% specificity, a positive predictive value and negative predictive value respectively of 88% and 98%.The TSM is a good mean for the diagnosis of the restenosis after an ATC
