  • Between Dec. 1984, and May, 1988,96 prostheses were implanted in 80 patients at Dept. of Thoracic k Cardiovascular Surgery of National Medical Center. 43 patients had mitral valve replacement, 21 underwent aortic valve replacement, and 15 had double valve replacement [Mitral k Aortic], and 1 had tricuspid valve replacement. Seventy-one cases [88.8 %] were in NYHA Class III or IV. The mean duration of follow up was 22.1 months and follow-up information was available for 74 [92.5 %] of the patients. The overall actuarial survival rate at 45 months was 93.05 % and overall hospital mortality was 10 %, late Mortality was 5 %. The linearlized incidence of thromboembolism [2.4%/pt-yr], thrombotic valve obstruction [1.6 %/pt-yr], anticoagulant related bleeding [0.8 %/pt-yr]. There were no fatal valve related complications. The blood was studied in 40 patients 1 year after valve operation. Hgb and reticulocyte count were within normal values and Serum LDH value was slightly elevated but it was not of clinical significance. In conclusion, Monostrut Bjork-Shiley valve prosthesis to be a reliable valve substitute with an acceptable incidence of complications.

  • 50 months experience with St-Jude Medical Cardiac Valve Prosthesis The St. Jude Medical valve has become our mechanical valvular prosthesis of choice because of favorable hemodynamic results that associated with marked clinical improvement and low incidence of thromboembolism. The data for this study was collected from April 1986 to May 1990, four years period. There were total of 110 patients[female 53, male 58] in this series with 22 isolated aortic valve, 66 isolated mitral valve, 20 double valve, 2 tricuspid valve replacement. The mean follow up time was 23 months. Postoperatively, 77% of cases were in New York Heart Association[NYHA] functional class I, and mild and moderate symptoms[NYHA II ] were present in 20% and there were very few patients remaining in higher functional classifications. In postoperative echocardiographic study showed marked improved cardiac function. The overall early mortality was 5.4% and was higher after double[13.3%] and mitral valve replacement[5.6%] and the late mortality was one case after mitral valve replacement due to endocarditis. The cause of death in early mortality was attributed to heart failure, acute renal failure, sepsis, etc.

  • Ebstein`s anomaly had been amenable to reparative surgery since 1962. However, neither the role of surgery in Ebstein`s anomaly nor the surgical procedure of choice for its correction are clearly defined. Whether or not the atrialized right ventricle, which plays a major role in the functional abnormalities, should be obliterated in all cases remains unsolved. Four cases of Ebstein`s anomaly treated surgically at Seoul National University Hospital were reported. All had closure of the atrial septal defect, obliteration of the atrialized right ventricle by plication, and insertion of a tricuspid bioprosthesis and an epicardial ventricular pacemaker. One patient had a pulmonic valvotomy due to stenotic bicuspid pulmonic valve also. All but one had discharged with a good result.

  • Ebstein anomaly is a rare congenital heart malformation typically involving the tricuspid valve and the right ventricle that has a wide range of anatomical and pathophysiological presentations. Various surgical repair techniques for Ebstein anomaly have been reported because of its near-infinite anatomical variability. Cone repair for Ebstein anomaly can achieve nearly anatomical reconstruction of the tricuspid valve with promising outcomes. In this article, the surgical techniques for cone repair in adult patients with Ebstein anomaly are described in detail, and clinical experiences and technically challenging cases are presented.

  • From April 1984 to April 1990, seven patients with Ebstein's anomaly underwent surgical repair. Mean age at operation was 18.6 years (range, 2 to 46 years). Operations were performed using hypothermic cardiopulmonary bypass. Surgical procedures included tricupid valve replacement (n:6) and tricuspid valve reconstruction (n: 1). There were two hospital deaths. There have been no late death. All survivors are in New York Heart Association class I or II with a median follow-up of 6.2 years(range, 4 to 8.3 years).

  • A 56-year-old male presented with severe exertional dyspnea and pitting edema in the lower extremities. The preoperative evaluation demonstrated biventricular dysfunction associated with severe tricuspid valve regurgitation and a persistent left superior vena cava. He was registered as a transplantation candidate, and orthotopic heart transplantation was performed using the standard bicaval technique. The left superior vena cava was connected to the right atrial appendage after the construction of a conduit using the recipient's autologous coronary sinus tissue. One-month postoperatively, computed tomography imagery demonstrated a patent conduit between the left superior vena cava and right atrial appendage.

  • We report a successful biventricular repair of D-transposition of great arteries, pulmonary stenosis and remote muscular inlet ventricular septal defect, after modifie Blalock-Taussing shunt early in infant. A long left ventricle-to-aorta intraventricular rerouting tunnel was created without stenosis by transferring the medial papillary muscle of the tricuspid valve to the tunnel, obliterating the trabeculation of right ventricle in the course of tunnel and excising the secondary chordae of the tricuspid valve.

  • From July 1984 to September 1990, 316 patients of congenital heart diseases were operated and 15 patients died. Hospital mortality was 4.75%. Five patients of 73 PDA had residual shunt after operation: 4 were ligated under support of Dacron patch, 1 was closed through the pulmonary arteriotomy under CPB. 3 patients were reoperated. No patient had residual shunt or reopening among the patients of simple ligation or division and suture. During the ligation of PDA, Dacron patch for protection from tearing may disturb the complete interruption of shunt. If the tissue around the ductus arteriosus looks weak or fragile, division and suture may be more reliable other than ligation with supporting patch. If the septal leaflet of tricuspid valve is adherent around the VSD, remained opening of VSD may be closed with simple suture directly. In these cases, the incidence of postoperative residual shunt is as high as the incidence of more large VSD closed with patch [10.9%: 9.6%]. During the direct closure of remained opening of VSD, another leaking route should be looked for carefully beneath the septal leaflet of tricuspid valve.

  • A 4-year-old, 6.1 kg intact female dachshund was referred to the Animal Medical Center with acute right hind limb lameness. Radiographs revealed fractures of iliac body and tibia in the right limb. In addition, the dog exhibited tricuspid valve regurgitation and moderate heartworm infection in the right ventricle and main pulmonary artery on echocardiogram. To obtain stable anesthetic conditions for operation, an adult heartworm removal procedure was previously followed by repair of the complex fractures. All surgical procedures were done without complication and with stable patient conditions. At a one month postoperative follow-up, the dog was doing well with normal ambulation and no tricuspid valve regurgitation as well.

  • A 6-month-old male Ragdoll cat presented with exercise intolerance. On physical examination, there was a grade 2/6 systolic murmur at the right apex. Diagnostic tests, including SpO2 measurement, blood tests, radiography, echocardiography, contrast echocardiography, and electrocardiography, were performed. Severe right atrial dilation, tricuspid valve leaflets and orifice displacement, right ventricular atrialization, septal leaflet adherence, anterior leaflet tethering, and right atrioventricular junction dilation were noted on echocardiography, alongside a right-to-left atrial septal defect. Cor triatriatum dexter and left ventricular aneurysm were observed. We diagnosed this case as having Ebstein anomaly with rare congenital heart deformities; which is rare in cats.
