Hace 1 día · The structure of coronary collateral circulation can provide sufficient oxygen supply to the vascular bed distal to a CTO. However, even with well-developed collaterals, patients might still experience symptoms, particularly during exertion, when collateral perfusion to the afflicted myocardium is insufficient, leading to ischemic myocardial areas ( 4 ).
Hace 1 día · Survival into adulthood is probably due to collateral development in the coronary circulation, with the risk of sudden death remaining high [4,5,6]. ALCAPA is, in most cases, an isolated defect, but in rare incidences, it has been described with other anomalies like tetralogy of Fallot, coarctation of the aorta, ventricular septal defects, and PDA ( 7 – 8 ).

One school-age patient with failing Fontan circulation and a complex network of aortopulmonary collaterals died 96 months postoperative from massive ...
Hace 2 días · The following data were collected from the patient’s medical records: age, sex, comorbid conditions (hypertension, diabetes, hyperlipidemia, atrial fibrillation, and coronary artery disease), smoking history, collateral circulation status, infarct volume, and admission to National Institutes of Health Stroke Scale (NIHSS) score.
Hace 4 días · Resumen. Antecedentes.El conocimiento exacto de la integración anatomofisiológica del sistema de conducción del corazón, es fundamental para la comprender la fisiopatología, el diagnóstico y el manejo de muchas de las complicaciones de la enfermedad coronaria y de las cardiopatías en general.
Hace 5 días · Coronary three-vessel disease (CTVD) accounts for one-third of the overall incidence of coronary artery disease, with heightened mortality rates compared to single-vessel lesions, including common trunk lesions. Dysregulated glucose metabolism exacerbates atherosclerosis and increases cardiovascular risk. The stress hyperglycemia ratio (SHR) is proposed as an indicator of glucose metabolism ...
Hace 1 día · This served to assess the potential for the creation of a large volume lesion/collateral damage with electrosurgery RF energy, and 2) ... The biological effects and the long-term performance of the lead (proarrhythmia, coronary artery spasm, capture thresholds, propensity for septal perforation and lead dislodgement) were not tested.
