BACKGROUND Although video-assisted thoracic surgery (VATS) pleural drainage and decortication have been proven to be effective treatments in the early stages of empyema, the optimal timing of VATS is still not clear. To assess the effectiveness of early VATS drainage and decortication, we reviewed the records of patients who underwent VATS and open(More)
We examined the pulsatility generated by an intra-aortic balloon pump/centrifugal pump (IABP/CP) combination in terms of energy equivalent pressure (EEP) and surplus hemodynamic energy (SHE). In five cardiac-arrested pigs, the outflow cannula of the CP was inserted into the ascending aorta, the inflow cannula in the right atrium. A 30-ml IABP was(More)
An injectable hydrogel was applied to regenerate a myocardial infarction and functional recovery of the heart. A myocardial infarction was induced in rat by circumflex artery ligation. A hyaluronic acid-based hydrogel was injected into the epicardium of the infarcted area. Then, cardiac functions and regeneration of the myocardium in sham-operated (SHAM),(More)
Hydrogel has been used for regenerating myocardial infraction (MI) as a delivery vehicle for cells and growth factors. This study showed that injectable hyaluronic acid (HA)-based hydrogels alone would effectively regenerate the damaged infarcted heart tissue. We found that there are two major factors of regeneration in MI. One is molecular weight of HA and(More)
The Twin-Pulse Life Support System (T-PLS) is a novel pulsatile extracorporeal life support system developed in Korea. It has been reported that the T-PLS achieves higher levels of tissue perfusion of the kidney during short-term extracorporeal circulation and provides more blood flow to coronary artery than nonpulsatile blood pumps. However, these results(More)
To evaluate the performance and safety of a newly developed blood warmer (ThermoSens), we tested its heating capability under various conditions using isotonic saline and hemolysis analysis with swine blood. The following two in vitro tests were performed: (i) To investigate the performance of the device, the inflow and outflow temperatures were measured at(More)
OBJECTIVES This study sought to demonstrate that short-term cardiac unloading with a left ventricular (LV) assist device (LVAD) after acute myocardial infarction (MI) can conserve calcium cycling and improve heart function. BACKGROUND Heart failure secondary to MI remains a major source of morbidity and mortality. Alterations in calcium cycling are linked(More)
At his final admission, 2 years after MVR, he returned for fever and oliguria of nearly 2 weeks’ standing. Routine blood tests showed the total number of leukocytes to be 2. 3 3 10 cells/L. Neutrophil ratio was 78.3%, and blood eosinophilic count was normal. The serum creatinine value was 142 mmol/L. TTE showed the bioprosthetic valve to be in good(More)
Percutaneous vertebroplasty is a minimally invasive technique that is used to treat vertebral fractures, tumors and osteolytic vertebral metastases. However, cement leakage to the venous system is a potential source of serious complications after percutaneous vertebroplasty. We report a 65-year-old female patient who demonstrated cardiac perforation,(More)
A 29-year-old female patient in the 28th week of pregnancy was diagnosed with a cardiac tumor. We performed tumor excision and mitral valve replacement, and her baby was born successfully with cesarean section on the 9th day after cardiac surgery. After this event, 8 cycles of chemotherapy were administered. After 10 months, metastatic intimal sarcoma of(More)
