Complete closure of(More)
OBJECTIVES To evaluate the diagnostic utility of myocardial perfusion by SPECT and Gated-SPECT in the diagnosis of acute coronary syndrome in patients with precordial pain associated with normal or doubtful ischemic ECG within the first 6 hrs of the last episode of pain. METHODS Sixty such patients who sought attention in the Emergency room were included.(More)
BACKGROUND The role of the right atrium in adaptation to the hemodynamic changes produced by extension of myocardial infarction (MI) of the left ventricular inferior wall to the right ventricle is fundamental.

However, its value in patients suffering from acute stent thrombosis has not been described. Herein, we present the intravascular ultrasound findings of a patient(More)
In order to determine the effect of right atrial dysfunction on clinical outcome, six patients with inferior myocardial infarction with extension to right ventricle and right atrium involving only obstructions of the right coronary artery were examined with transesophageal echocardiography (TEE) at the time of the event. Five of the patients were reexamined(More)
Percutaneous mitral commissurotomy (PMC) has emerged as an effective nonsurgical technique for the treatment of patients with symptomatic mitral stenosis.
