The present study reports 41 cases of congenital and acquired heart diseases, who received open heart surgery under extracorporeal circulation [ECC] by Sarns Heart-Lung-Machine [HLM] at the Department of Thoracic and Cardiovascular Surgery, Hanyang University Hospital during the` period between July 1975 and February 1979. The priming of pump oxygenator was carried out by the hemodilution method using Hartman`s solution, whole blood, and fresh human plasma. The rate of hemodilution was in the average of 50.8 ml/kg. ECC was performed at the average perfusion flow rate of 85.0 ml/kg/min [2.43 L./ kg/2] and at moderate hypothermia. In the total cardiopulmonary bypass, arterial pressure ranged between 55 mmHg and 90 mmHg, but generally maintaining over 70 mmHg. Patient age ranged between 2 and 54 year old, in congenital heart diseases, between 2 and 28, in acquired heart diseases, between 17 and 54 Sex ratio of male to female was 20:21. The cases include a case of pulmonary valvular stenosis, 4 cases of atrial septal defect, 9 cases of ventricular septal defect, 9 cases of tetralogy of Fallot, 5 cases of pentalogy of Fallot, 3 cases of atypical multiple anomalies 7 cases of mitral stenosis or insufficiency, a case of myxoma in left atrium, and a case of ruptured aneurysm of Valsalva`s sinus. The surgical managements were 16 valvulotomy for pulmonary valvular stenosis, 2 Teflon patch graft closure and 5 simple suture closure of atrial septal defect, 16 Teflon patch graft closure and 5 simple suture closure of ventricular septal defect, 12 pericardial patch graft for infundibular stenosis of right ventricle, one anastomosis between left superior vena cava and right atrium, 2 open mitral commissurotomy, 5 mitral valve replacement using Starr-Edward`s ball valve, porcine xenograft by Hancock, by Carpentier-Edward, or Angell-Shiley, one removal of left atrial myxoma, and a repair of ruptured aneurysm of Valsalva`s sinus. Four [9.7%] out 41 cases expired postoperatively and the rest of 37 cases survived with satisfactory results. The causes of death were one coronary embolism in tetralogy of Fallot, 2 postoperative lower cardiac output in atypical multiple anomalies, and one right heart failure in large: ventricular septal defect with pulmonary hypertension.

Open heart surgery begun at 1959 in Korea. From that time to 1979, the surgery was performed below 100 cases in a year. However,that was performed above, 1,000 cases in a year from 1981. During the recent three years, i.e., 1985, 1986, and 1987, the annual operative cases were 3614,4503, and 4906, and then the mortality rates were progressively decreased to 6.2%, 5.3 %, and 5.0 %. In these time, overall mortality rate above 1 year old was 5.0 % versus that below 1 year old 17.9 9o in congenital heart diseases. These results are statistically different between two groups. Of the valvular heart disease cases, which occupied 97 % of total acquired heart disease, individual incidence was in mitral 68 %, and aortic 28%. The operative method was mainly valve replacement. Operative mortality for valve surgery in total was 4.4 %. Until 1985, bioprosthetic valve was frequently implanted but mechanical valve has been done more frequently in these days. Coronary artery bypass graft was large portion [67 * 75 %] of open heart surgery in western, but was below 1 % in Korea. However our diet patterns have been changed. Therefore we think the incidence of coronary artery disease will be increased. So we will be familiar to this field.

Background: Heart failure can develop secondary to various heart diseases (e.g. mitral valvular insufficiency, congenital heart defects, heart worm infection). The clinical signs of heart failure can be confused with those of other conditions, such as respiratory disease. Therefore, specific, sensitive, rapid and inexpensive blood tests for heart failure are desirable. Cardiac troponins, natriuretic peptides and cytokines have been more recently used as indicators of heart disease in humans and animals. These peptides are sensitive to changes in vasoconstriction and dilation within the heart and are used for the diagnosis and prognosis of heart failure. Methods: Previously developed and newly developed cardiac biomarkers will be discussed for understating clinical implications and diagnostic values in heart diseases in small animals

One hundred and fourteen patients were underwent cardiovascular operation from the 11th June 1985 to 12th July 1988 in the department of cardiovascular surgery of Seoul District Hospital. There were one hundred and one open heart surgery patients and thirteen non-open heart surgery patients. Of open heart surgery cases, seventy-four were acyanotic, twenty four were cyanotic congenital heart disease and three were acquired valvular heart disease. VSD was most common[55 cases] among acyanotic group and TOF[21 cases] was most common among cyanotic group. Of non-open heart patients, there were eleven cases of PDA and two cases of shunt[modified Blalock-Taussig shunt using PTFE graft] for TOF. There were one operative death[0.9%] due to inadequate relief of right ventricular outflow tract obstruction and peripheral pulmonary artery stenosis for TOF patient. No Patients were dead during follow-up.

One hundred cases of open heart surgery were done at this Department in 1977. There were 65 congenital anomaly and 35 acquired diseases. Out of 65 cases of congenital malformation 35 acyanotic and 30 cyanotic cases were found. Fifteen cases of ventricular septal defect and 29 tetralogy of Fallot were noted eight patients expired out of 65 congenital anomaly [12.3%] , 4 out of 35 acyanotic [11. 4%] and 4 among 30 cyanotic anomaly[13.3%]. Among 35 cases of acquired heart disease 3 atrial myxoma [2 left and one right] and 32 valvular lesions were noted. In two cases open mitral commissurotomy, and in 30 valve replacement were done. Twenty-two single valve and 8 double valve replacement were done. Seven patients expired out of 30 patients [23.3%]. Among 22 single valve replacement cases 2 and among 8 double valve 5 died. ~ In eighteen mitral valve replacement cases 2 deaths occurred. One mitral insufficiency patient who expired suffered from severe pulmonary` hypertension [PA=120/67mmHg], tricuspid insufficiency and a large ventricular septal defect. The patient underwent mitral valve replacement, tricuspid annuloplasty and patch closure of ventricular septal defect. Over all mortality rate for 100 open heart surgery cases was 15%. Since 1977 open heart surgery cases were done routinely in this institution and cases are increasing rapidly. With present rapid improvement of economical status and introduction of medical insurance system, open heart surgery will be firmly established in Korea in the very near future.

A 4-year-old female Fox Terrier dog (weighting 8 kg) with history of severe abdominal distention and anorexia was presented to Veterinary Teaching Hospital, Gyeongsang National University. In physical examination, grade 4/6 systolic murmur heard at the left heart base. Electrocardiography showed right ventricular enlargement (right axis deviation and deep S wave) and right atrial enlargement (P pulmonale). Diagnostic imaging studies revealed hypertrophy of right ventricle, enlargement of right atrium and tricuspid regurgitation and turbulence in the pulmonary artery in right parastenal short axis view. Based on the diagnostic findings, the dog was diagnosed as a case of valvular pulmonic stenosis.
