Methods Quantitative angiography was performed on 60 cases (67 successfully dilated lesions) after angio-plasty over 6-months follow-up, and both univariate and multivariate logistic regression analysis were done to i-dentify the correlations of restenosis with clinical factors. Results The total restenosis rate was 31. 3% (21 of 67 lesions), and according to univariate analysis the patients who underwent coronary stenting≥ 3. 5mm had a lower rate of restenosis ( P < 0. 01). Collateral circulation to the obstruction site, high maximal inflation pressure, smoking and the less minimal lumen diameter after PTCA made the rate of restenosis higherower ( P < 0. 05) . Multivariate logistic regression analysis showed that coronary stenting ≥3. 5mm had a low rate of restenosis, but high maximal inflation pressure and smoking made the restenosis rate higher. Conclusion Coronary stent size, maximal inflation pressure and. smoking were independent predictors for restenosis.展开更多

The aim of this study was to assess the clinical profile, angiographic status, and prevalence of restenosis in patients who underwent percutaneous transluminal coronary angioplasty (PTCA) in LMCA. Materials and Methods: This observational cohort study included 17 patients who underwent PTCA in LMCA during one-year study period at tertiary care centers in Government Medical College, Kozhikode, India. Data including various risk factors, clinical and angiographic details, stent used, procedural complications and outcomes including rate of restenosis were analyzed. Results: A total of 17 patients (mean age 53.88 ± 9.80 years) with 76.47% of males were included in the study. Smoking and hypertension were the most common risk factors presented in 52.94% and 47.06% of patients respectively. Single vessel disease (SVD) of LMCA was the most common pattern observed in 47.10%;the rate of restenosis was observed in 11.76% patients. Revascularization was performed in one patient (5.88%) with coronary artery bypass graft and in one patient (5.88%) with PTCA using drug eluting stent (DES). The overall procedural success was 88.24% in this study. Survival rate was 100% at one-year follow-up period. Conclusion: Our study involved patients who underwent PTCA in LMCA, showed smoking as a most prevalent risk factor for coronary artery disease and SVD as a most common pattern, comparatively low rate of restenosis and 100% of survival rate at one-year follow-up period.展开更多

The therapeutic concept of DEBs is promising, notably on the basis of initial studies in patients with diffuse in-stent restenosis (ISR). At present, however, a number of questions regarding long-term efficacy and safety remain, specifically in indications other than diffuse ISR. The results of the evaluation of different substances, balloon systems and clinical indications will determine the long-term success of DEBs.展开更多

Methods: Forty-six consecutive de novo lesions treated with a single >2.5 mm drug-eluting stent under intravascular ultrasound guidance, using two implantation strategies, were randomly assigned to: 1) pre-dilation with a non-compliant balloon (NC group;n = 23) or 2) pre-dilation with a dual wire scoring balloon (DS group;n = 23). Results: Although the balloon size and the maximal dilation pressure for pre-dilatation was larger (3.33 ± 0.28 vs 3.09 ± 0.33 mm, p = 0.01) and higher (11.6 ± 3.2 vs 8.6 ± 2.7 atm,展开更多

METHODS: A total of 69 patients with in-stent restenosis were divided into 2 groups randomly: cutting balloon angioplasty and plain old balloon angioplasty. The mechanisms of restenosis and dilation results were determined by quantitative coronary angiography and intravascular ultrasound. Follow-up was performed. RESULTS: The procedural success rate was 100% without death and acute closure. One patient experienced dissection at the distal end of the stent and needed another stent. The mean follow-up period was 6.7 +/- 2.3 months. The final re-restenosis rate was 15% and 18% at 3 months and 6 months respectively, markedly lower than after plain old balloon angioplasty (38% and 43%). Acute gain by intravascular ultrasound (IVUS) was 1.72 +/- 0.52 mm after cutting balloon angioplasty, higher than 1.15 +/- 0.54 mm after plain old balloon angioplasty. The lumen diameter late loss in the cutting balloon group was 0.26 +/- 0.05 mm and 0.38 +/- 0.06 mm at 3 months and 6 months respectively, significantly lower than for those in conventional balloon group (0.78 +/- 0.19 mm and 0.89 +/- 0.16 mm, respectively, P展开更多
