The exact pathogenesis of transient mid- and basal ventricular ballooning, a new variant of transient left ventricular (LV) ballooning, remains unknown. We report two cases of transient mid- and basal ventricular ballooning associated with catecholamines. These cases suggest that catecholamine-mediated myocardial dysfunction might be a potential mechanism(More)
BACKGROUND Although the modified Simpson's method is widely used for the assessment of left ventricular ejection fraction (LVEF), it has limitations including relatively high inter- and intra-observer variability and time consuming nature. We want to evaluate whether assessing mitral annular systolic velocity (S' velocity) by tissue Doppler imaging (TDI)(More)
Cor pulmonale (CP) is defined as the structural and functional alternation of the right ventricle (RV) caused by primary disorders of the respiratory system. We aimed to differentiate acute CP complicated with massive pulmonary thromboembolism (PTE) from the chronic form due to severe chronic obstructive pulmonary disease (COPD) with strain analysis of RV(More)
BACKGROUND Epicardial fat is a visceral thoracic fat and known to be related with presence of dyslipidemia and coronary arterial stenosis. We evaluated the effects and differences of statins on epicardial fat thickness (EFT) in patients underwent successful percutaneous coronary intervention (PCI). METHODS In this retrospective cohort study, we enrolled(More)
BACKGROUND Assessment of right ventricular (RV) systolic function remains difficult because of the RV's complex shape. We aimed to evaluate RV systolic function with strain analysis in patients with acute pulmonary thromboembolism (PTE). PATIENTS AND METHODS From March 2005 to June 2006, 28 consecutive patients with acute PTE were included in this study.(More)
