Effect of primary percutaneous coronary intervention on myocardial repolarization.

Objective: We aimed to investigate the effect of coronary perfusion on QT interval dispersion in patients with acute myocardial infarction (MI).

Methods: Seventy-seven consecutive patients who had undergone primary percutaneous coronary intervention (PCI) for a first ST segment elevation MI during the first 12 h of symptom onset were included in the study. After achievement of thrombolysis in MI (TIMI) 3 flow of the infarct-related artery, corrected TIMI frame count (cTFC) and TIMI myocardial perfusion grade (TMPG) were measured.

Assessment of coronary veins in patients with isolated coronary artery ectasia by antegrade coronary venous angiography.

Background: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. The most common cause of CAE is atherosclerosis but other possible etiologies include congenital abnormalities and inflammatory and connective tissue disease. Earlier studies have documented the association of CAE with the presence of aneurysms in other vascular beds.

Isolated pulmonic valve endocarditis in an adult patient with ventricular septal defect and infundibular pulmonary stenosis.

Ventricular septal defect associated with infundibular pulmonary stenosis is a relatively uncommon congenital cardiac defect. We report the first case of a patient with perimembranous small ventricular septal defect and infundibular stenosis suffered from pulmonary valve endocarditis and septic pulmonary embolism.
