Reference diameter was larger in the Penta group.
Target vessel with reference diameter> 2.0 and< 2.75 mm.
In a previous study performed at our institution, predictors of new coronary artery bypass grafting of the target vessel were identified:diabetes mellitus, reference diameter of the target vessel and length of the lesion.
Dg0 is the reference diameter of the aggregate admitted as 16 mm;
Views in which lesion diameter was found least regarding to reference diameter was used for analysis.
All injuries with reference diameter> 1.5 mm were included in the comparative analysis for the present study.
The mathematical formula proposed estimates the plaque volume based on the reference diameter, minimal luminal diameter and lesion length.
After the implant, the reference diameter was 2.50 mm and the minimal luminal diameter was 2.54 mm fig.
Reimbursement covers Cyphertm andTaxustm stents for patients indicated for revascularization of one vessel with a reference diameter less than 3 mm and a stenosis length greater than 15 mm.
In the present study, stent reference diameter, minimum lumen diameter, and acute gain were higher in the Penta stent group.
In the distal reference segment, the vessel area was 9.94± 3.51 mm,the lumen area was 6.27± 1.98mm, the percentage of stenosis was 35.39± 13.31% and the reference diameter was 2.82± 0.43mm.
Univariate and multivariate analyses revealed the reference diameter as an independent predictor of restenosis.
The reference diameters were measured in places considered to be angiographically normal, at 5 mm proximal and distal to the lesion, when possible.
Thus, manufacturers would only have to make one size stent for all vessels with a reference diameter> 2.5 mm even up to 4mm!, and one size would fit all situations.
The proximal and distal reference diameters were obtained from the mean between the highest and lowest axis of the external elastic membrane in mm.
In the proximal reference segment, the vessel area was 15.13± 4.36 mm,the lumen area was 7.62± 2.55mm, the percentage of stenosis was 48.68± 11.47% and the reference diameter was 3.10± 0.51mm.
Lesion length, minimal lumen diameter, reference diameter and percent diameter stenosis were measured at these sites.
Angiographic inclusion criteria were the presence of de novo lesion with>50% diameter stenosis in native coronary arteries, with reference diameter> 2.5 mm and< 4 mm and length< 20 mm.
Quantitative results- Proximal reference diameter by tomography was 3.01± 0.31 mm and by quantitative angiography, 3.14± 0.31 mm p 0.04.
Proximal and distal reference diameters of the coronary artery in mm, for the calculation of reference vessel diameter through simple mean;
This case had a lesion type of 1,1,0 Medina classification with< 70-degree angle,main vessel proximal reference diameter of 3.2 mm, distal reference diameter of 2.7 mm and lateral vessel diameter of 2.2 mm.
The vessel reference diameter was significantly smaller in the Latin American population 2.75 mm vs. 2.90 mm; P< 0.001; however, the stenosis diameter was greater in the non-Latin American population 83.2% vs. 80.6%; P< 0.001.
Univariate analysis showed that diabetes mellitus,post-implantation reference diameter, lesion length and stent type had a statistically significant association with restenosis.
The coronary plaques were defined as the presence of image with soft tissue density>= 1 mm compatible with coronary atheromatosis,whereas the degree of luminal stenosis was defined as the ratio between the smallest luminal diameter at the lesion and the reference diameter closest to the lesion.
Before the procedure, the mean lesion length, reference diameter, and stenosis diameter were 19.0± 8.0 mm, 3.03± 2.2 mm, and 80.4± 14.1%, respectively.
Inclusion criteria were coronary artery disease andclinical indication for elective coronary stenting, target vessel reference diameter> 2.5 mm, and successful interventional procedure according to the AHA/ACC/SCAI 2005 Guideline Update for PCI.
Semi-objective measurement algorithms were used to measure the reference diameters and minimum lumen diameter which, in turn, could allow the diagnosis of the presence of stenoses and, in positive cases, the estimate of their severity.
The lesions were treated with standard stent implantation procedures, via a femoral artery approach, andthe choice between predilatation with a balloon catheter 0.5mm smaller than the reference diameter and post-dilatation with a balloon catheter shorter than the stent with increasing diameter balloon/artery ratio< 1.1/1 was left to the investigator's discretion.
Some trials required an infarction-related artery minimal reference diameter of at least 2.5 mm or 2 mm. Patients with left main coronary stenosis were excluded from 6 trials and those with excessively calcified and tortuous arteries were excluded from one trial.
