Unroofed coronary sinus syndrome is an uncommon anomaly, Unroofed coronary sinus syndrome is caused by incomplete formation of the left atriovenous fold, and it usually is associated with Left SVC. If it is not diagnosed, a residual reversed or bidirectional shunt will result, and its complications will reduce life expectancy. We experienced 3 cases of unroofed coronary sinus syndrome which combines TOF with PLSVC, partial ECD, primum type ASD. In case of Unroofed coronary sinus syndrome which combines TIF with PLSVC, preoperative diagnosis was not made. In corrective operation for TOF of this case, pump weaning was failed due to hypoxia and cardiac arrest, and he expired at operation room. At autopsy of this case, complete unroofed coronary sinus was found. In the other 2 cases, partial unroofed coronary sinus syndrome was found in operation field and corrective operation was performed successfully. We report these 3 experiences with its review. ^u ++ Noninvasive Assessment of Pressure Gradients across Prosthetic Heart Valve by Doppler Ultrasound - A comparative study of the Duromedics Bileaflet Valves in mitral position and Normal Mitral Valves -with its review.

Transposition of the great arteries is one of the commonest forms of severe congenital heart disease and produces severe cyanosis threatening survival from the day of birth. Anatomical anomalies which the aorta arises from the infundibulum of the right ventricle and the pulmonary artery arises from the outflow tract of the left ventricle make the deranged circulation. Survival is possible only if additional anomalies are present which allow mixing of the pulmonary and systemic circulations. Preoperative diagnosis as TGA was taken on the 15 day old female via the preoperative examination and the right cordioangiography. As palliative treatment for cyanosis, Blalock-Hanlon operation was performed in this patient. The results were good as 54 mmHg changed from 27 mmHg of $PO_2$ in aorta, but sudden cardiac arrest was developed in postoperative 12 hours. In order to confirm the cause of death and the cardiac anomalies, autopsy was performed on the date of death. The diagnosis of the autopsy showed; [1] Transposition of the Great Arteries. [2] Patent Ductus Arteriosus. [3] Patent Foramen Ovale. [4] Ventricular Septal Defect, 2 Muscular Type. [5] Double Ureter, Right. [6] Artificial Atrial Septal Defect. [7] Total Collapse of the left lung and Intraparenchymal hemorrhage of right lung.

Pancreatitis is a known complication of cardiac surgery with cardiopulmonary bypass. Although ischemia is believed to be a factor, the exact cause of pancreatitis after cardiopulmonary bypass remains unknown.We prospectively studied 67 consecutive patients undergoing cardiac surgery with cardiopulmonary bypass for evaluation of the pancreatic injury after cardiopulmonary bypas. Serial measurement of amylase level in serum and urine was done postoperatively. Hyperamylasemia was detected in 15 patients[22.4% , of whom no patient had pancreatitis. There was no significant difference between serum amylase level and parameters such as cardiopulmonay bypass time, aortic cross clamp time, mean blood pressure, rectal temperature, flow rate, and use of circulatory arrest during cardiopulmonary bypass. Hyperamylasuria was detected in 8 patients[11.9% , and urine amylase level was elevated significantly in the groups with prolonged cardiopulmonary bypass, mean blood pressure more than 40mmHg, and rectal temperature more than 20 $^{\circ}$C. We recommend that serum amylase level and/or amylase-creatinine clearance ratio is measured for ealy detection and management of pancreatitis after cardiopulmonary bypass.

A 43-year-old man who had had a history of atrial septal defect (ASD) device closure 31 months previously presented with abrupt chest and back pain along with progressive cardiogenic shock and cardiac arrest. After resuscitation, he was diagnosed with cardiac tamponade. Diagnostic and therapeutic surgical exploration revealed left atrium (LA) perforation due to LA roof erosion from a deficient aortic rim. Device removal, primary repair of the LA perforation site, and ASD patch closure were performed successfully. The postoperative course was uneventful. The patient was discharged after 6 weeks of empirical antibiotic therapy without any other significant complications.

In a dental treatment, a dentist has to know the possibility to happen all kinds of the emergency and to prepare for managing that situation. Especially, the cardiac arrest is the most serious emergent problem. If the accident were happened, most dentists got embarrassed. The American Heart Association (AHA) is offering the Basic Life Support (BLS), Advanced Cardiopulmonary Life Support (ACLS) and Pediatric Advanced Life Support (PALS) programs for the healthcare who need to prepare the life threatening situation. The PALS is specialized to someone who participate in pediatric health-care field. This program is composed of three major emergency problems, such as respiratory emergencies, shock and cardiac arrests. The main concepts of the PALS are early recognition and systemic team approach. The purpose of this study was to introduce about PALS and to prepare response system for emergencies in the dental environment.

As the number of passengers using aircraft increases around the world, there may be more medical measures needed within the aircraft. These medical measures may also include measures against serious situations such as cardiopulmonary resuscitation (CPR). However, since the environment is different from the hospital in the aircraft, it may be difficult to cope with such a situation. Moreover, such in-flight CPR may become more difficult at a time when the proportion of out-ofhospital CPR is decreasing due to the recent COVID-19 pandemic. In this paper, I would like to summarize how in-flight CPR is performed and review the main discussions on CPR in the COVID-19 pandemic, and finally suggest how to perform a safe CPR in the COVID-19 situation.

This 3-year-old girl was observed frequent exertional dyspnea and cyanosis at crying since birth. She was not premature baby and delivered at full term normally. On physical examination, she was underdeveloped-body weight 13.5 kg, height 99 cm.- and cyanotic. There was severe clubbing on fingers. There was grade II/VI ejection systolic murmur on left lateral border of the sternum. The preoperative examinations [EKG, echocardiogram, cardiac catheterization and biventriculogram] showed that complicated T.G.A. combined vena cava[S.D.D.]. Preoperatively, we decided the corrective surgery of Rastelli operation using a. pulmonary valved conduit. The operation was performed under total circulatory arrest using deep profound hypothermia combining with extracorporeal circulation. On operation, the anatomy of the heart showed that, 1. The subaortic conus was seen and subaortic muscles were hypertrophied. 2. The VSD[type II], behind the subaortic conus-about 1 cm. in diameter, was visible only through LV cavity and, 3. The pulmonary valve ring was hypoplastic and pulmonary valvular stenosis was seen also. The subpulmonic area [LV outflow tract] was obstructed with hypertrophied muscle and mitral valve. 4. Left superior vena cava was drained to RA via coronary sinus. 5. LAD coronary artery was originated from right coronary artery and ran anterior to the pulmonary artery. According to above anatomy, we performed the VSD closure with Teflon patch, and Mustard operation combined with LV-to-pulmonary artery bypass graft using the valve contained [Hancock 16 mm] conduit. Postoperatively, adequate blood pressure could be maintained under the state of using inotropic agent [epinephrine]. On the second postoperative day, the patient died of cardiac arrest due to low cardiac output syndrome, acute renal failure and pulmonary edema.
