  • A 17-year-old male patient was referred with symptoms of dyspnea. Multi-detector computerized tomography (MDCT) and echocardiography evaluation revealed quadricuspid aortic and pulmonary valves, an atrial septal defect (ASD), and pulmonary stenosis. We closed the ASD using a bovine patch and performed a commissurotomy of the pulmonary valve. Quadricuspid semilunar valves are very rare congenital abnormalities that are reported to occur nine times more frequently in the pulmonic valve than in the aortic valve. According to the Hurwitz Roberts classification, the aortic valve was type A, and the pulmonic valve was type B. The aortic valve normal function, but the pulmonic valve was stenotic and had abnormal function.

  • This is a genuine case report of the Ross operation without the use of homografts or heterografts in reconstruction of the right ventricular outflow tract. A 8-year-old boy with congenital aortic stenosis underwent aortic valve replacement with a pulmonary autograft and right ventricular outflow tract reconstruction with a pericardial conduit bearing autologous aortic monocusp. The postoperative echocardiography and cardiac angiography revealed good ventricular function and competent neoaortic valve. He has been followed up for 19 months.

  • Absent pulmonary valve syndrome with intact ventricular septum(APVS with IVS) is a rare congenital anomaly. The severe form of this syndrome, characterized by severe respiratory distress presented soon after birth, has been attributed to the compression of the airways caused by aneurysmal dilatation of pulmonary artery. Several operative treatments such as pulmonary valve insertion, or reductive angioplasty of pulmonary artery have been applied. We present a 3-day-old male who showed improvement after PDA ligation, reductive angioplasty of pulmonary artery, pulmonary valve reconstruction, and ASD closure.

  • Between Jan. 1986 and Aug. 1992. 72 patients underwent Rastelli procedure. There were 43 male and 29 female, aged 46 days to 16 years [mean age, 5.2 years] with 18 patients less than 2 years of age. All patients had complex defect, 27 pulmonary atresia with ventricular septal defect, 18 corrected transposition of great arteries with pulmonary atresia or punmonary stenosis, 10 truncus arteriosus, 10 double outlet right ventricle with pulmonary atresia or stenosis, 7 complete transposition of great artersia with pulmonary atresia or pulmonary stenosis. The types of extracardiac valved conduit used were prosthetic valve[n=47, 24 car-bomedics, 19 Ionescu-Shiley, 4 Bjork-shiley] and hand-made trileaflet valve using pericardium. [n=23, 20 bovine pericardium, Z autologous pericardium, 1 equine pericardium] The mean size of valved cinduit was 5.25mm larger in diameter than the size of main pulmonary artery. [normalized to the patient`s body surface area] There were 17 hospital death[24%] and 4 late deaths[5.6%]. Postoperative complication rate was 38.9%a, none of which was conduit-related. All patients were followed pos-toperatively for 1 to 73 months. [mean 25.8 months] During follow-up period, reoperation was done in 6 patients due to stenosis of valved conduit. Mean interval between intial repair and reoperation was 20.3 months. In our experience, li recently extracardaic valved conduits between right ventricle [or pulmonary ventricle] and pulmonary artery were inserted with increasing frequency in infants less than 2 year, but hospital mortality was decreased, 2] Risk of reoperation due to conduit stenosis is low, so that the effect of graft failure on overall survival is minimized. 3] Nevertheless, because any type of extracardaic valved conduit is not ideal in children, we recommended that Lecompte should be done if cardiac anatomy is permitted.

  • A modified Fontan procedure was performed on two patients with Univentricular heart. The first patient had UVH of right ventricular type with trabecular pouch and had various associated anomalies, such as common atrium, common atrioventricular valve and combined pulmonary stenosis. The second patient had UVH of left ventricular type with outlet chamber and the associated anomalies were atrial septal defect, tricuspid stenosis and combined pulmonary stenosis. Postoperative hemodynamic insufficiency, fluid retention and renal insufficiency were occurred in the first patient, but relieved with the aid of inotropics and vasodilators. We thought that the good postoperative course and surgical result were gained from the widely patent atriopulmonary anastomosis.

  • A 1.3 year-old Castrated male Bedlington terrier (10.0 kg of body weight) was presented with heart murmur and occasional coughing. Diagnostic imaging studies revealed supravalvular pulmonic stenosis (maximal velocity 2.91 m/s) from abnormal membranous structure (aperture) distal to the pulmonary valve in the main pulmonary artery. Further study also revealed pulmonic regurgitant (1.82 m/s of peak velocity, 13.2 mmHg of pressure gradient) jets started from the abnormal membranous structure. Since the dog had no obvious clinical signs related to heart failure, no interventional therapy including balloon dilation was considered in this case. Instead, medical treatment for preventing further deterioration of clinical signs related to PS was done with enalapril. This case report described a rare case of type III supravalvular PS in a dog, which has never been reported. Further deterioration of clinical signs has yet been recognized after medical treatment.

  • A 15-year-old girl underwent successful surgical correction of double-outlet right ventricle [S.D.L.] subaortic ventricular septal defect, patent foramen ovale, and pulmonary hypoplasia with valvular stenosis. The operation consisted of an internal baffling connecting the left ventricle to the aorta through the ventricular septal defect. The pulmonary stenosis was corrected with the method of connection the right ventricle to the pulmonary artery bifurcation using the Hancock valve[18mm] contained conduit. This rare type of DORV seemed to be suitable for corrective surgery, and the patient`s condition is very good until present time (post operative 7 months).

  • Percutaneous pulmonary valvuloplasty was performed in 19 patients of congenital pulmonary valve stenosis. Pulmonary annulus diameter was estimated by cross sectional echocardiography and right ventricular cineangiography. The size of balloon dilatation catheter was chosen by the same size of the estimated pulmonary annulus in the first 3 patients and 20 \ulcorner30% greater than the annulus in the last 17 patients. After valvuloplasty a satisfactory results was obtained in most patients. Before dilatation, the right ventricular systolic pressure was 91.7 mmHg[range 58-150 mmHg] and it fell to 49.2mmHg[25-85 mmHg] after dilatation. The transvalvular gradient was 67.7 mmHg[33 \ulcorner120 mmHg] before dilatation and it fell to 23.7mmHg [5 \ulcorner62] after dilatation. Repeat cardiac catheterization has been scheduled in all patients 3 months after the initial valvuloplasty but follow up recatheterization was performed in only two patients; in one of them residual gradient of 50 mmHg was reduced to 30 mmHg by repeat valvuloplasty. The other patient showed no evidence of restenosis with transvalvular gradient of 20 mmHg The balloon used for valvuloplasty was single balloon for the first 10 cases and for the later 10 cases it was replaced by Trefoil balloon which was easier for inflation and deflation. There were no significant complications during and after the procedure. From our results, we conclude that balloon valvuloplasty for congenital pulmonary valve stenosis is the treatment of choice in most patients.

  • Hemoptysis occurs quite frequently as a consequence of mitral stenosis, but massive, lirE threatening pulmonary hemorrhage is distinctly unusual. We report a 30 year old female who underwent cmcrgcncy rcdo double valve replacement for intractable pulmonary hemorrhage. she underwent mitral valve replacement (lonescu Shirley 27 mm) due to rheumatic valvular heart disease in 1984 and tricuspid valve annuloplasty (Carpentier's rlng 30mm) two years later She was admitted for massive hcmoptysis and dyspnea on the 26th of December, 1995. Medical treatment including transarterial embolization was given but was not satisfactory. Emergency valve replacement (Mitral valve , 51. Judc 29mm and tricuspid valve ; 51. Jude 33mm) was performed and hemoptysis was controlled dramatically 24 hours after surgery.

  • 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.
