Myocardial Blush Grade

Background: The TIMI myocardial blush grade (MBG) has been shown to be a strong angiographic predictor of mortality in patients with TIMI 3 flow after primary angioplasty. This study was conducted to evaluate the relationship between regional myocardial perfusion quantified by cardiac magnetic resonance and angiographic reperfusion score defined by MBG. Methods: We studied 29 consecutive patients (25 men, age 63±13 years) with ST-segment elevation acute myocardial infarction (LAD lesion: 12, RCA lesion: 16, LCx lesion: 2) who underwent primary angioplasty within 6 hours from the onset and showed TIMI grade 3. MBG was determined on angiography at the end of angioplasty. All patients underwent rest myocardial perfusion MRI during initial hospitalization, and regional MBF (ml/min/g) was quantified by using a Patlak plot method. Myocardial perfusion (MP) ratio was calculated from quantitative perfusion MRI, as MBF in infarction area/MBF in normal area. The optimal cut-off value of MP ratio that can predict MBG 3 on coronary angiography was determined by using a receiver-operating characteristic (ROC) analysis. Results: In 29 patients with TIMI 3 flow after angioplasty, 4 patients had MBG 0–1, 7 had MBG 2 and 18 had MBG 3. The MP ratio in MBG 3 group calculated from quantitative perfusion MRI was significantly higher than the MP ratios in MBG 0 –1 group and MBG 2 group (0.96±0.18 vs. 0.48±0.25, P<0.001; 0.96±0.18 vs. 0.66±0.19, P=0.003, respectively). There was no significant difference between the MP ratios in MBG 0 –1 group and MBG 2 group. The ROC curve revealed that MP ratio of 0.74 is an optimal threshold to distinguish MBG 3 from MBG 0 –2, with a high area under the curve of 0.90. Conclusions: The result of this study demonstrates that MP ratio quantified from rest perfusion MRI correlated well with MBG on coronary angiography.

Angiographic Score

This paper reports the cost of endovascular materials used for the treatment of large-vessel ischemic stroke in the anterior circulation according to the angiographic score and clinical results at three months. From November 2009 to July 2011, 57 ischemic patients (mean age, 64.6 ±13.8 years) with anterior large vessel occlusion were included. Mean National Institutes of Health Stroke Scale (NIHSS) on admission was 18.4 ± 4.9. Mean duration of symptoms until the arterial puncture was 207±67 minutes. Recanalization was assessed using the Thrombolysis In Myocardial Infarction (TIMI) score. Patient selection was performed on a non-enhanced CT scanner. According to the TIMI final angiographic score and the modified Rankin score (mRS) at three months, we determined the cost of the material used. Complete (n=12, TIMI grade 3) or partial perfusion (n=35, TIMI grade 2) was achieved in 47 (82.5%) lesions. At three months, 33.3% (n=19) had a mRS score ≤ 2. The mean cost of the material used in the operative room was 5018±2402 euro. Intra-arterial thrombolysis presents a substantial initial cost and the long-term economic impact has to be evaluated. Our health system has to take the price of these new technologies into account for future medical choices and urgently evaluate them in randomized controlled trials.

Aim: The transradial approach (TRA) has taken an upswing, however access-site complications still exist. The choice of potentially less traumatic materials may minimize these complications. This article describes the use of a hydrophilic-coated 6F guiding catheter for diagnostic and interventional procedures and upper extremity dysfunction following these procedures. Materials and Methods: This prospective observational study enrolled 217 patients who underwent elective transradial percutaneous coronary intervention (TR-PCI) for stable and unstable angina, or acute coronary syndrome between May 2014 and November 2016. All patients were treated using a 6F hydrophilic-coated guiding catheter (PRIMUM, PendraCare, Wellinq, the Netherlands). Catheter performance was assessed on a five-point scale ranging from very bad to very good. Procedure safety was assessed using the Major cardiac and cerebrovascular events (MACCE) criteria. Results: The average number of guiding catheters used was 1.2 per patient. Overall performance of the catheters was rated Average/Good. Procedural success, defined as TIMI grade 3 flow and successful stent deployment, with a residual diameter stenosis of <25%, was 97.7%. MACCE occurred in 1.5% during the 6-months of follow-up. Conclusion: These data indicate that the use of a hydrophilic-coated guiding catheter to perform percutaneous coronary interventions is safe and effective, with high procedural success and low complication rates. In addition, the short and long-term MACCE outcomes of the PCI were favorable.
