Determinants of coronary collateral circulation (CCC) in human heart are still incompletely identified. In acute non-ST elevation myocardial infarction (NSTEMI), abrupt vessel occlusion results in myocardial necrosis in the jeopardized area. Angiographic collaterals to myocardial tissue distal to an acutely occluded coronary vessel can reduce infarct size and risk for post-infarct complications as well as infarct related mortality. These prognostic implications of collateral function, makes it n...

Coronary-cameral fistula (CCF) is a rare condition most commonly caused by an embryologic developmental anomaly. Fifty-five percent of CCFs originate from the right coronary artery, 35% from the left coronary artery, and 5% from both. More than 90% of them drain into the venous system and low pressure sites such as the right ventricle (41%), right atrium (26%), pulmonary artery (17%) and only 3% drain into the left ventricle or atrium....

Dilated cardiomyopathy, which mostly has an idiopathic etiology or is caused by genetic inheritance or infection, may cause irreversible congestive heart failure. Hypocalcemia is a rare etiology of reversible dilated cardiomyopathy. Cardiogenic shock related to hypocalcemic cardiomyopathy is a rare event. Here we report two cases with congestive heart failure who was diagnosed as having dilated cardiomyopathy secondary to hypocalcemia....

A 28-year-old pregnant woman was admitted to our hospital with tonic seizure and dyspnea, and was diagnosed with acute massive pulmonary embolism. An emergency surgical embolectomy was performed under cardiopulmonary bypass (CPB). Several fragments of the thrombi were carefully removed from the right and the main pulmonary arteries, and sufficient back-flow from the pulmonary artery was established. The postoperative course was uneventful. After the embolectomy, the ratio of pulmonary to systemi...

Background:The effect of pulmonary vein isolation (PVI) on left ventricular (LV) function after restoration of sinus rhythm remains unclear in patients with chronic atrial fibrillation (CAF). This study aimed to evaluate LV systolic function in the early phase after PVI using speckle tracking echocardiography.
Methods:Twelve patients with CAF could be restored to sinus rhythm by PVI and maintained sinus rhythm after PVI. Echocardiography was performed before, immediately after and 3 months afte...
