		                        			A 65-year-old woman was referred for management of chest pain and ST segment elevation on electrocardiography. Emergency coronary angiography revealed a well demarcated thrombus that near totally occluded the mid portion of the left anterior descending artery, with a Thrombolysis In Myocardial Infarction (TIMI) flow grade 1, and a fusiform aneurysm on the left main coronary artery. No significant stenosis was observed after aspiration of the thrombus; however, complete coronary reperfusion by urgent aspiration did not improve her dyspnea and tachypnea. Echocardiography revealed a D-shaped left ventricle; thus, we performed a chest computed tomography scan and diagnosed a pulmonary embolism. The patient's coagulation studies were normal. She was prescribed chronic anticoagulation, and we carried out transthoracic echocardiography using second harmonic imaging with agitated saline. Second harmonic imaging with the Valsalva maneuver revealed no right-to-left shunt. We report here a case of concurrent coronary embolism and pulmonary embolism without right-to-left shunt.

		                        			PURPOSE: To report a case of a primary conjunctival epithelial cyst in the orbit. CASE SUMMARY: A 60-year-old woman was referred for evaluation of proptosis of the left eye, which had developed about 2 years earlier. Upon initial examination, a movable mass was palpated in the medial aspect of the left orbit. Magnetic resonance imaging of the orbit showed a 2.5 cm-sized, ovoid, cystic mass located between the left eyeball and the medial wall of the orbit. Excisional biopsy of the orbital mass was performed. The orbital mass was a well-circumscribed cystic lesion, adherent to the medial rectus muscle. Histological examination revealed that the cyst was lined with multiple layers of cuboidal epithelium with goblet cells. A diagnosis of primary conjunctival cyst was made. CONCLUSIONS: The possibility of primary conjunctival cyst should be considered in the differential diagnosis for an orbital cystic mass.

		                        			BACKGROUND: Extracorporeal membrane oxygenation (ECMO) during severe acute respiratory failure helps to recover the pulmonary function. This study evaluated our experience with veno-venous ECMO in adult patients with acute respiratory failure. METHODS: From January 2007 to July 2009, ECMO was used on 54 patients. Of these 54 patients, 7 were placed on veno-venous ECMO for acute respiratory failure. The indications of ECMO were based on the lung dysfunction measured as a PaO2/FiO2 ratio <100 mm Hg on FiO2 of 1.0, or an arterial blood gas pH <7.25 due to hypercapnia despite the optimal treatment. EBS(R), Bio-pump(R), and Centrifugal Rotaflow pump(R) were used and all cannulations were performed percutaneously via both femoral veins. When the lung function was improved, an attempt was made to wean on ECMO at moderate ventilator settings followed by decannulation. RESULTS: Five of the 7 patients were male and the mean age was 46.3+/-18.3. The causes of acute respiratory failure were 3 cases of pneumonia, 2 near-drownings, 1 pulmonary hemorrhage due to acute hepatic failure and 1 mercury vapor poisoning. The mean support time of ECMO was 17.3+/-13.7 days. Of the 7 patients implanted with ECMO, 5 patients (71%) were weaned off ECMO and 3 patients (43%) survived to hospital discharge after a mean 89.6 hospital days. CONCLUSION: The early use of ECMO for acute respiratory failure in adults due to any cause is a good therapeutic option for those unresponsive to the optimal conventional treatments.

		                        			It is essential during extracorporeal membrane oxygenation (ECMO) to extend the activated clotting time (ACT) using anticoagulants to prevent blood clot formation. Traditionally, heparin has been used as an anticoagulant during ECMO. Hemorrhaging due to systemic heparinization is considered a major complication of ECMO. A 48-year-old man was admitted due to cardiogenic shock with acute myocardial infarction. ECMO was instituted because of recurrent ventricular tachycardia and refractory shock. We used nafamostat mesilate (Futhan) as an anticoagulant to reduce hemorrhagic complications. The total bypass time was 153 h. The average dose of nafamostat mesilate was 2.64+/-1.11 mg/kg/h; the average ACT was 128.68+/-21.24 seconds. Only a few units were transfused, and there was no oxygenator failure or hemorrhagic complications. Thus, nafamostat mesilate may reduce the need for transfusions and hemorrhagic complications during ECMO.

		                        			Danon disease is characterized clinically by the triad of cardiomyopathy, myopathy and mental retardation. It was originally reported as a lysosomal glycogen storage disease with normal acid maltase by Danon. Danon disease results from mutations in lysosome associated membrane protein-2 (LAMP-2) gene. The LAMP-2 gene is located on Xq24-25. We report a case of suspected Danon disease in patient who had hypertrophic cardiomyopathy and mental retardation along with abnormal findings in electromyography.

		                        			BACKGROUND AND OBJECTIVES: Right ventricular (RV) dysfunction is associated with a poor prognosis in patients with an acute pulmonary embolism (APE). We studied the role of electrocardiography and biomarkers for early detection and recovery of right ventricular dysfunction (RVD) in APE. SUBJECTS AND METHODS: The medical records of 48 consecutive patients diagnosed with APE using CT-angiography, at the Kangdong Sacred Heart Hospital, between January 2004 and February 2008 were reviewed retrospectively. RVD was assessed by serial echocardiography (ECG). Patients with one of the following were considered to have RVD: 1) RV dilatation (enddiastolic diameter >30 mm in the parasternal long axis view), 2) RV free wall hypokinesia, and 3) paradoxical septal systolic motion. We compared the electrocardiographic findings and the biomarkers for the early detection of RVD. RESULTS: The electrocardiographic findings showed T-wave inversion (TWI) in leads V1 to V3 with a sensitivity of 75% and a specificity of 95%, and a diagnostic accuracy of 80% for the detection of RVD, with positive and negative predictive values of 95.5% and 73.1%, respectively; these results were better than the biomarkers such as cardiac enzymes or B-type natriuretic peptide (BNP) for the early detection of RVD. TWIs persisted throughout the period of RVD, in contrast to a transient S1Q3T3 pattern detected during the acute phase only. CONCLUSION: TWIs in leads V1 to V3 had the greatest sensitivity and diagnostic accuracy for early detection of RVD, and normalization of the TWIs was associated with recovery of RVD in APE.

		                        			A 48-year-old woman visited the emergency department with shock due to a urinary tract infection. The patient, who had a history of hypertension and diabetes mellitus, presented with precordial ST-segment elevation and Q waves, along with an increase of cardiac enzymes. An echocardiography showed moderately reduced systolic function, severe apical left ventricular ballooning, and a dynamic left ventricular outflow tract obstruction with a pressure gradient of 109 mmHg. Coronary angiography demonstrated normal coronary arteries. At the 1-month echocardiographic follow-up, the apical ballooning and left ventricular systolic function had recovered completely. There was no residual left ventricular intra-cavity gradient at rest, but it was induced in low-dose dobutamine stress-echocardiography. We demonstrated that dynamic left midventricular obstruction in the setting of either increased catecholamine stress or hypovolemia could develop Tako-tsubo cardiomyopathy.

		                        			Oxidative stress plays various roles in the development and progression of IgA nephropathy, while bilirubin is known as a potent antioxidant. We therefore hypothesized that serum bilirubin would be associated with renal prognosis in IgA nephropathy. The study subjects comprised 1,458 adult patients with primary IgA nephropathy in Korea. We grouped patients according to the following quartile levels of bilirubin: <0.4 mg/dL (Q1), 0.4-0.5 mg/dL (Q2), 0.6-0.7 mg/dL (Q3), and >0.8 mg/dL (Q4). The outcome data were obtained from the Korean Registry of end-stage renal disease (ESRD). Eighty patients (5.5%) contracted ESRD during a mean follow-up period of 44.9 months. The ESRD incidences were 10.7% in Q1, 8.2% in Q2, 2.8% in Q3, and 2.8% in Q4 (p<0.001). The relative risk of ESRD compared to that in Q1 was 0.307 (95% confidence interval [CI], 0.126-0.751) in Q3 and 0.315 (95% CI, 0.130-0.765) in Q4. The differences of ESRD incidence were greater in subgroups of males and of patients aged 35 yr or more, with serum albumin 4.0 g/dL or more, with normotension, with eGFR 60 mL/min/1.73 m2 or more, and with proteinuria less then 3+ by dipstick test. In conclusion, higher bilirubin level was negatively associated with ESRD incidence in IgA nephropathy.

		                        			Persistent tricuspid regurgitation (TR) caused by infarction or ischemia of right ventricle (RV) is rare and has not been reported by coronary vasospasm previously. We reported the two cases of patients with persistent right heart failure (HF) and severe TR by coronary vasospasm. After RV infarction or ischemia, two-dimensional (2D) echocardiographic examination revealed normal left ventricular function, but RV hypokinesia, RV and tricuspid annular dilation, and severe TR with normal appearance of tricuspid valve itself. Subsequent coronary angiography and cardiac catheterization revealed coronary vasospasm without significant coronary artery stenosis and pulmonary hypertension. Repeated echocardiography showed persistent right HF and severe TR at 5 years and 4 months later in respective cases. In conclusion, we suggest that RV infarction or ischemia with coronary vasospasm can be one of the causes for isolated TR and tricuspid annular dilation.
