Coronary chronic total occlusions (CTOs) are commonly encountered in patients undergoing coronary angiography. Several observational studies have demonstrated that successful CTO revascularization

Prediction of side branch occlusions in percutaneous coronary interventions by coronary computed tomography: the CT bifurcation score as a novel tool for predicting intraprocedural side branch occlusion. EuroIntervention 2019;15:e788-e795. A CTO was defined as a complete occlusion of a major epicardial coronary artery existing for at least six weeks (mean, 7 +/- 5 months). Myocardial wall thickening and left ventricular volumes were quantified on cine-images, and the transmural extent of infarction (TEI) was scored on delayed-enhancement images. However, variables affecting the late angiographic outcome of coronary stenting in the setting of a total occlusion have not been elucidated sufficiently. METHODS: Coronary stenting was performed in 143 consecutive patients with a nonacute total occlusion; 120 of these patients (84%), with a total of 121 occlusions, underwent repeat angiography within 6 months and comprised the study group.

The patient was rushed for a repeat coronary angiogram.PCI of the LM and left anterior descending(LAD)arteries was Coronary arterial dominance is defined by which coronary artery gives rise to the vessels that supply the inferior aspect of the heart. In this right-dominant heart, the RCA gives rise to the posterior descending artery and posterolateral ventricular branch (PLVB) and supplies the posterior one-third of the interventricular septum and inferior Occlusions of the left main coronary artery are extremely dangerous because obstruction at that level disrupts blood flow through both the left anterior descending artery and the circumflex, causing ischemia, injury, or infarct of a large part of the heart muscle. Ocular ischemic syndrome occurs at a mean age of 65 years, is rare before 50, has no racial predilection. Men are affected twice as often as women likely due to the higher incidence of atherosclerotic disease in males. Bilateral involvement may occur in up to 22% of cases. The particular predilection for the proximal portion of the coronary arteries maybe due to the blood supply, which is via nutrient arteries of narrow calibre in the young.

Percutaneous coronary interventions (PCI) of coronary chronic total occlusions (CTO) increase the risk of high radiation exposure for both the patient and the cardiologist. This study evaluated the maximum dose to the patients’ skin (MSD) and the exposure of the cardiologists during CTO-PCI.

Percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) is increasingly being performed in patients with advanced coronary artery disease, but there is limited information on the techniques utilized and the procedural outcomes.

Interventional interventions in patients with IHD with chronic coronary occlusions are among the most difficult for technical implementation of interventions [1-4]. Recanalisation of Chronic Total coronary Occlusions: 2012 Consensus document from the EuroCTO club Coronary artery disease (CAD), also known as coronary heart disease (CHD), ischemic heart disease (IHD), or simply heart disease, involves the reduction of blood flow to the heart muscle due to build-up of plaque (atherosclerosis) in the arteries of the heart. It is the most common of the cardiovascular diseases.

ABSTRACT. The management of chronic total coronary occlusions (CTO) is still today one of the greatest challenges of cardiology.

Coronary chronic total occlusions (CTO), in spite of excellent progress in the field of medicine, remain a great challenge for interventional cardiologists. CTO is defined as the occlusion of a coronary artery with a thrombolysis in myocardial infarction (TIMI) score of 0 flow estimated for >3 months duration.

Chronic total occlusions (CTO) have been found in 18%–52% of patients with coronary artery disease (CAD) who undergo coronary angiography.1–4 Successful percutaneous coronary intervention (PCI) of CTOs has been demonstrated to significantly improve symptoms, left ventricular function and patient survival compared with failed procedures.5–8 With appropriate patient selection, these 2016-10-30 · Wang et al. demonstrated that acute coronary occlusions leading to segment elevation myocardial infarction (STEMI) seem to predominately occur in predictable spots within the proximal third of the coronary arteries and that for each 10 mm increase in distance from the ostium, the risk of an acute coronary occlusion significantly decreased by 13–30%, depending on the coronary vessel . 2021-01-30 · Background Diabetes mellitus (DM) is highly prevalent among patients undergoing percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). Therefore, the purpose of our study was to investigate the clinical outcomes of CTO-PCI in patients with or without DM. Methods All relevant articles published in electronic databases (PubMed, Embase, and the Cochrane Library) from Percutaneous coronary interventions (PCI) of coronary chronic total occlusions (CTO) increase the risk of high radiation exposure for both the patient and the cardiologist.
