Article Abstract

Background: Patients with left main coronary artery stenosis often have complex coexisting coronary artery disease. Surgical revascularization is still the standard modality of treatment.

Objective: To present our experience in surgical revascularization for patients with stenosis of both left main and right coronary artery and evaluate the impact of the latter on the outcome of surgery.

Methods: From 2006 to 2015, a total of 46 patients (38 male and 8 female, mean age 56.3 years) underwent coronary artery bypass grafts for stenosis of both left main and right coronary artery. Risk factors for coronary artery disease were identified in 93.4%. EuroSCORE II was 2.2 ± 4.29. All were operated on pump with mean grafts 3.3 ± 0.8.1 per patient. Intraaortic balloon was inserted in 11 patients.

Results: Early postoperative mortality was 8.7%. Regarding complications, we reported bleeding in 6 patients, sternal wound infection in 5, renal impairment in 5, respiratory complications in 2, and myocardial infarction in 4.

Conclusion: Surgical revascularization for patients with stenosis of both left main and right coronary artery has a higher morbidity and mortality when compared to results of surgery for isolated left main disease.

Feasibility of on-site CT-FFR analysis on cardiac photon-counting CT in evaluation of hemodynamically significant stenosis in comparison to invasive catheter angiography.

Objectives: Coronary CT angiography (CCTA) is an excellent tool in ruling out coronary artery disease (CAD) but tends to overestimate especially highly calcified plaques. To reduce diagnostic invasive catheter angiographies (ICA), current guidelines recommend CT-FFR to determine the hemodynamic significance of coronary artery stenosis. Photon-Counting Detector CT (PCCT) revolutionized CCTA and may improve CT-FFR analysis in guiding patients.

Aims: To identify differences in CT-derived perivascular (PVAT) and epicardial adipose tissue (EAT) characteristics that may indicate inflammatory status differences between post-treatment acute myocardial infarction (AMI) and stable coronary artery disease (CAD) patients.

Methods And Results: A cohort of 205 post-AMI patients (age 59.8±9.

This paper proposes the use of artificial intelligence techniques, specifically the nnU-Net convolutional neural network, to improve the identification of left ventricular walls in images of myocardial perfusion scintigraphy, with the objective of improving the diagnosis and treatment of coronary artery disease. The methodology included data collection in a clinical environment, followed by data preparation and analysis using the 3D Slicer Platform for manual segmentation, and subsequently, the application of artificial intelligence models for automated segmentation, focusing on the efficiency of identifying the walls of the left ventricular. A total of 83 clinical routine exams were collected, each exam containing 50 slices, which is 4,150 images.
