PURPOSE Adipose-derived stem cells (ADSCs) are known to be potentially effective in regeneration of damaged tissue. We aimed to assess the effectiveness of intracoronary administration of ADSCs in reducing the infarction area and improving function after acute transmural myocardial infarction (MI) in a porcine model. MATERIALS AND METHODS ADSCs were(More)
BACKGROUND AND OBJECTIVES It was demonstrated that the fractional flow reserve (FFR) with partial balloon obstruction may have implications for assessing viable myocardium. In a different way, the index of microcirculatory resistance (IMR) was introduced as a useful indicator for assessing microvascular function. We evaluated the relationship between the(More)
BACKGROUND/AIMS Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening complication after acute pulmonary embolism (APE) and is associated with substantial morbidity and mortality. This study aimed to investigate the incidence of CTEPH after APE in Korea and to determine echocardiographic predictors of CTEPH. METHODS Among 381(More)
Percutaneous device closure for secundum atrial septal defects (ASDs) has been performed commonly and safely with high success rates. However, it is still challenging to close ASDs that are surrounded with deficient or hypermobile rims and could be compromised with an unexpected migration of device. We report a case of percutaneous Amplazter Septal Occluder(More)
BACKGROUND AND OBJECTIVES Thoracic endovascular aortic repair exhibits limitations in cases where the aortic pathology involves the aortic arch. We had already developed a fenestrated aortic stent graft (FASG) with a preloaded catheter for aortic pathology involving the aortic arch. FASG was suitable for elective cases. MATERIALS AND METHODS An aortic(More)
BACKGROUND AND OBJECTIVES Statins remain the mainstay of secondary coronary artery disease (CAD) prevention, but n-3 polyunsaturated fatty acids (ω-3 PUFA) display biological effects that may also reduce the risk of atherosclerosis and CAD. However, data on the possible antiatherosclerotic benefits of adding ω-3 PUFA to statin therapy are limited. This(More)
Coronary cameral fistula (CCF) is a rare anomaly, where a communication exists between an epicardial coronary artery and a cardiac chamber. Assessing the hemodynamic significance of the fistula is crucial to make a decision concerning the management process. We present two cases of CCF, draining into the left ventricle, in which the hemodynamic significance(More)
