11/610. Post-Mustard procedure pulmonary venous obstruction: An opportunity for anatomic correction with a one-stage arterial switch. A 14-year-old boy after a Mustard procedure for transposition of the great arteries developed pulmonary hypertension secondary to baffle obstruction. This occurred over several years without apparent significant symptomatology. Systemic-level pressure prevailed in the left (pulmonary) ventricle and provided an opportunity to perform a successful one-stage arterial switch. ( info) |
12/610. Palliative arterial switch for complete transposition with ventricular septal defect. A 28-year-old female patient with complete transposition, ventricular septal defect and persistence of the arterial duct underwent a palliative arterial switch procedure in 1976 at 7 years of age. Therefore, she has survived for 22 years and lives a near normal life. She is married, has been counselled against pregnancy and has increasing cyanosis with the typical features of the Eisenmenger syndrome. ( info) |
13/610. Double-switch operation for congenitally corrected transposition and Ebstein's malformation. An infant is described with congenitally corrected transposition and Ebstein's malformation. Banding of the pulmonary trunk had been previously performed because of a muscular ventricular septal defect. The patient underwent the double-switch procedure with the intention of unloading the morphologically right ventricle and the malformed tricuspid valve. This resulted in prompt postoperative functional and haemodynamic improvement. ( info) |

| The repair of a corrected transposition of the great arteries, ventricular septal defect, and pulmonary atresia is presented. An ebstein anomaly of the tricuspid valve, dextrocardia, and severe distortion of the pulmonary arteries complicated the surgical procedure, which was performed in two stages. Reconstruction of the pulmonary arteries and a bidirectional cavopulmonary anastomosis were performed first; Rastelli and hemi-Mustard procedures completed the correction. The rationale and the possible indications of this "one and a half ventricle" repair are discussed. ( info) |
16/610. Peters' anomaly: dominant inheritance in one pedigree and dextrocardia in another. Two case reports are described to illustrate the unusual occurrence of dominant inheritance of Peters' anomaly and the concomitant occurrence of Peters' anomaly with colobomatous microphthalmos and dextrocardia. Studies of additional families are necessary to determine conclusively the pathogenesis, genetic mode of inheritance, ocular and systemic associated malformations, and proper management of this complex entity.

17/610. Aortopulmonary collateral artery embolization during postoperative extracorporeal membrane oxygenation after arterial switch procedure. Aortopulmonary collateral arteries sometimes complicate cyanotic congenital heart defects. Combined with a relevant left-right shunt, this could result in massive airway bleeding during and after corrective surgery. A preoperatively diagnosed 1.2 mm small aortopulmonary collateral artery in a newborn suffering from transposition of the great arteries caused life-threatening airway bleeding during surgery. Postoperative extracorporeal membrane oxygenation (ECMO) was necessary, and coil embolization was performed on ECMO to terminate pulmonary bleeding. ( info) |
18/610. Intraatrial mitral valve insertion with native valve preservation in children. Two patients underwent intraatrial mitral valve insertion for an unsuccessful valvotomy for severe mitral stenosis and left-sided atrioventricular valve insufficiency associated with corrected transposition utilizing a porcine valve from a valved conduit with preservation of the native valve. The valves were inserted using continuous suture distally at the mitral annulus and proximally at the pulled atrial wall distal to the pulmonary veins. Both patients had uneventful hospital course and are doing well at up to 6 months postoperatively. This approach provides a viable option for congenital mitral stenosis or insufficiency in children.

19/610. Changes of management in a patient with double outlet left ventricle. Double outlet left ventricle is an extremely rare anomaly. Until recently, the diagnosis was usually established by angiography or at postmortem. There are only a few reports describing the echocardiographic findings in this lesion, and as far as we know, no report showing the anatomy as well as the velocity and pattern of flow by color Doppler echocardiography. The patient reported here underwent surgery at the age of four years, when an aortic homograft was placed between the right ventricle and the pulmonary trunk. This biventricular repair had to be changed into a Fontan-type procedure, 15 years later since the hypoplastic right ventricle did not grow adequately. ( info) |
20/610. Double outlet left ventricle with subpulmonary ventricular septal defect and pulmonary hypertension. A two-month old male infant with the rare occurrence of double outlet left ventricle, subpulmonary ventricular septal defect and pulmonary hypertension is presented. The infant was managed temporarily with banding of the pulmonary trunk, with a favorable result, and is scheduled for definitive intraventricular repair. ( info) |
