Methods: Elective asymptomatic patients with aneurysm > 20 mm and symptomatic patients with endovascular therapy of PAA were included. The proportion of patients with critical limb ischemia (presence of rest pain or tissue loss) was high at 32.1%, 21.6% of the patients had acute ischemia with symptoms persisting shorter than 14 days. The primary study endpoint was the target lesion revascularization (TLR) rate at 12 months. Secondary endpoints included technical success, periinterventional adverse events, primary patency at 6, 12 and 24 months, TLR rate at 24 months, predictors on reintervention, change in in clinical symptoms using the Rutherford-Becker classification (RBC), amputation and mortality rate. One hundred thirty-four patients (68.3±10.6 years, 88.8% male) were treated with a Viabahn® endoprosthesis (W.L. Gore & Associates Inc., Flagstaff, AZ, USA). Results: The average aneurysm diameter was 2.5±0.87 cm. In 41%, occlusion of the aneurysm was present. TLR rate was 31.3% and 38.8% after 12 and 24 months, respectively. Primary patency rates were 69.1%, 52.3% and 42.6% at 6, 12 and 24 months, respectively. Univariate logistic regression analysis revealed age as a predictor of reintervention and in the multivariable analysis it was treatment with lysis. An improvement in RBC was seen at all-time points. Two major amputations (1.5%) were performed and the mortality rate at 24 months was 5.2%. Conclusion: Primary patency rate after endovascular exclusion of PAA is low. However, limb salvage rate is high.","PeriodicalId":72523,"journal":{"name":"Cardiology and cardiovascular medicine","volume":"6 6","pages":"550-557"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9912976/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10709582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cardiology and Cardiovascular Medicine 6 (2022): 340-352. Abstract Aims and background The incidence of coronary artery anomaly is rare in the general population, anomalous origin of right coronary artery being the most common. These anomalies, particularly anomalous coronary arteries with an interarterial course (ACAIAC) are potentially dangerous. Due to their low incidence, meticulous clinical and imaging guidelines have not yet been defined in assessing such patients and guiding management. Methods and results CT coronary angiograms of patients who underwent the study for exclusion of coronary artery disease were reviewed. Patients with ACAIAC were recorded. The images were reviewed and reconstructed to measure the caliber and area of the narrowest interarterial segment of ACAIAC in systolic and diastolic phases using Philips Intellispace version 12.1 software. Percentage change in area (p value 0.093) and diameter (p value 0.108) of the interarterial segment in systolic and diastolic segments, was statistically significant between anomalous coronaries with high and low interarterial course. Percentage change in area and diameter between patients with positive and negative TMT findings was also statistically significant (p<0.001 in both cases). Conclusion Significant positive correlation between change in vessel caliber in the interarterial course of coronary arteries during the cardiac cycle and TMT findings, suggests elevated risk of inducible ischemia in patients with significant vessel compression. Hence the change in vessel caliber demonstrated by CT imaging can be used as a potential criterion for risk assessment and management of patients with ACAIAC. in a to the long axis of ACA. Optimal image representative of vessel cross section was selected. Images were viewed with 2-3X magnification and dimensions and area of IAS of coronary were manually at multiple by two observers blinded for clinical details and earlier Range of diastolic and narrowest systolic caliber and area of the interarterial segment of anomalous coronary artery Record of estimated average radiation dose per examination was made.","PeriodicalId":72523,"journal":{"name":"Cardiology and cardiovascular medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69346711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
