We have experienced a patient, 16 year-old male, with ventricular septal defect with tricuspid recur- gitation due to blunt chest trauma. He suffered from congestive heart failure after the trauma. Echocardiogram and cardiac catheterization revealed left to right shunt at the ventricular level (muscu- far portion of interventricular septum) and tricuspid regurgitation. At the time of the operation, marked systolic thrill was palpable over the rlght ventricle near the apex and a chorda tendina was seen sharply ruptured just near the medial papillary muscle. We repaired the ventricular septal defect with a Dacron patch and chordal reconstruction with autologous pericardium. The postoperative course was uneventful and the patient was discharged in good condition.

This is a report of a successful, rapid two-stage arterial switch operation in an infant with dextrotransposition of great arteries with an intact ventricular septum beyond the appropriate time for arterial switch operation.'A 4-month-old female infant was admitted due to severe cyanosis, respiratory insufficiency, and frequent dia rhea secondary to ischemic colitis. Echocardiographic examination presented marked leftward deviation of the interventricular septum, and left and right ventricular pressures as measured by cardiac catheterization were 40/4 mmHg and 85/2 mmHg, respectively. Fifteen days after a preparatory operation (pulmonary artery band with modified right Blalock-Taussig shunt), left ventricular-right ventricular systolic pressure ratio increased to 105/90. Arterial switch operation associated with the division of the right Blalock-Taussig shunt and the removal of pulmonary artery band was performed. A(leer the operation, the infant showed normal cardiac function with no postoperative complication.

Ultrasonogram for kidney, spleens liver, intestine and heart was evaluated 11 Chriu horses and 14 Thoroughbred horse. The kidney was determined at both flan and both 17th intercostal spaces. The spleen was determined at the left 13-17 intercom spacer and the liver was determined at the right 7-13 intercostal space. The heart was determined at the right 4-6 intercostal space and left 3-6 intercostal space. The length, of rig kidney at the Thoroughbred horse, Thoroughbred foul, Cheju horse and Cheju foul were 16.2, 12.6, 13.1 and 11.2 mm, respectively. The width of right kidney at the Thoroughbed horse, Thorughbred foul, Cheju horse and Cheju foul were 5.4, 4.3, 4.6 and 4.2 mm, respectively. The depth of right kidney at the Thoroughbred horsed Thoroughbred foul, Cheju horse and Chrju foul were 5.2, 4.4, 4.5 and 4.3 mm, respectively. Similar ultrasonographic measurements were obtained for the left kidney, The left ventricular end-diastolic diameter at the Thoroughbred horse, Thoroughbred fouls Cheju horst and Cheju foul were 107, 83, 85 and 73 mm, respectively. The left ventricular end-systolic diameter were at the Thoroughbred horse, Thoroughbred foul, Cheiu horse and Cheiu foul were 63, 52, 53 and 45 mm, respectively. Also, the interventricular septum in end-diastole, interventricular septum in end-systoles left ventricular wall end-diastoles left ventricular wall end-systoles right ventricular end-diastole diameter, aorta and left atrium at t Thoroughbred horse, Thoroughbred foul, Chriu horse and Chriu foul were measured. Experimental renal stone and enterolith of colon were observed by ultrasonography.

Hypertrophic cardiomyopathy is characterized by inappropriate hypertrophy of the myocardium and is associated with various clinical presentations ranging from complete absence of symptoms to sudden, unexpected death. These are caused by dynamic obstruction of the left ventricular outflow tract and surgical approaches were initiated. But, the complete resection of hypertrophied midventricular septum is impossible by standard, transaortic approach, because of narrow vision and limited approach. And it leads to inadequate excision, will leave residual left ventricular out-flow tract obstruction or systolic anterior motion of mitral leaflet, and limit symptomatic improvement and patient's survival. We report a case of extended septal myectomy for hypertrophic cardiomyopathy of mid-septum in a child. The extended septal myectomy was performed by aortotomy and left ventricular apical incision, and made possible the complete resection of mid-ventricular septum, abnormal papillary muscles and chordae. The patient's symptom was improved and the postoperative course was uneventful.

The unusual congenital anomaly, double chambered right ventricle due to aberrant muscle band with intact ventricular septum in 10 years old female patient is presented. The pressure gradient is 70mmHg between inflow tract and outflow tract of right ventricle and the aberrant muscle band is 2X4.5cm arising below the infundibulum and traverses the right ventricular cavity, extending from its anterior wall to the crista supraventricularis forming broad triangular base in parietal anterior wall. By resecting out this muscle band clearly, the outflow tract obstruction is completely relieved.

A 15 year-old boy was referred to us because of mild dyspnea on exertion and incidentally found heart murmur. On echocardiography, a mass involving mainly interventricular septum and causing left ventricular outflow tract obstruction was detected. Cardiac catheterization demonstrated a transaortic pressure gradient of 20 mmHg. Partial excision of the septal mass was performed via aortotomy under cardiopulmonary bypass. The pathologic diagnosis revealed myocardial hamartoma. The lesion was mainly composed of mature, severely hypertrophic myocytes and intervening fibrosis. During the 5 year of follow-up after the surgery, no evidence of arrhythmia or tumor recurrence was documented.

A direct communication between the left ventricle and right atrium is a relatively uncommon defect. Familiarity with this anomaly has become increasingly important, however, since the preoperative findings may be identical with those of an atrial septal defect. The left ventricle is directly related to the right atrium over. an area of the membranous ventricular septum which extends superior to the septal attachment of the right atrioventricular valve in the LV-RA communication. The clinical triad of a ventricular septal defect murmur, cardiac enlargement, and an arteriovenous shunt at atrial level is characteristic of the malformation. A 2-year-old boy with left ventriculo-right atrial communication has operated at the Maryknoll Hospital. Under the cardiopulmonary bypass, the atrium was opened, there was a jet-blood stream just above the atria-ventricular portion adjacent to the septal leaflet of the tricuspid valve.

Primary tumors of the heart are extremely rare, and about 25 per cent of primary cardiac tumors are malignant. Recently, We experienced a case of primary cardiac liposarcoma occurred on the right ventricular outflow tract and extended into the main pulmonary artery. The patient was 57 year-old man and the chief complaints was severe exertional dyspnea. Emergency operation to relieve the right ventricular outflow tract obstruction was performed under cardiopulmonary bypass. The tumor was 5$\times$4$\times$3 cm in size and infiltrated into the right ventricle and ventricular septum. The tumor in the main pulmonary artery was removed without any difficulty but the on the right ventricular outflow tract was difficult to remove completely. The patient was recovered without any specific problems. After successful surgical resection and postoperative radiotherapy the patient discharged with good condition. Herein, the clinical characteristics of cardiac liposarcoma, the problems in differential diagnosis, the prognosis and current therapy are reviewed.

A 2-year-old, spayed female, American shorthair cat presented with acute weight loss, tachypnea, and dyspnea. The cat had grade V holosystolic murmur and systemic hypotension. Echocardiography showed a 9 mm defect in the ventricular septum, left-to-right dominant bi-directional shunt, right ventricular hypertrophy, pulmonary stenosis, pulmonary hypertension, and overriding aorta. The cat was diagnosed with a Tetralogy of Fallot. The cat was treated with furosemide, pimobendan, ramipril, and sildenafil. Treatment reduced pulmonary infiltration, pulmonary vessel enlargement, and main pulmonary artery bulging. However, right-to-left flow increased over time and right ventricular outflow tract velocity was elevated. Currently, the patient has maintained an improved state for 1 year. This case report described a severe inherited feline Tetralogy of Fallot case that was successfully managed for a long time.

After early surgical repair of ventricular septal rupture complicated by myocardial infarction, newly developed ventricular septal defects were discovered on the 7th and the 40th postoperative day in 2 cases. We reoperated these patients for closure of newly developed ventricular septal defects with Dacron patch successfully on the 77th and the loth day after discovery of those defects. From these results we conclude that early surgical rep ir for ruptured ventricular septum following myocardial infarction is an appropriate approach with low risk and that remnant or recurred ventricular septal defect can be corrected rather safely with proper myocardial preservation and unrestricted application of intraaortic balloon pump or other ventricular assist device.
