    Abstract: Twenty-six patients with atrioventricular discordance and a variety of ventriculo-arterial connections have had appropriate intracardiac repairs. Seven of 26 patients (26.9%) died early postoperatively, but only two (11.1%) of 18 patients operated upon since May 1972 have died. Ten patients (40%) developed permanent complete heart block. Two patients died late postoperatively; 16 (84.1% of those surviving the early postoperative period) were in NYHA Class I or II at late follow-up. Seventeen of the patients had "corrected transposition." Six developed tricuspid incompetence with regurgitation into the left atrium after repair. Two patients with atrioventricular discordance and double outlet right ventricle survived operation and are asymptomatic but have permanent pacemakers. One patient died after repair of double outlet left ventricle with atrioventricular discordance. Three of four patients with atrioventricular discordance and "pseudotruncus arteriosus" survived repair with valved external conduits and are well. One of two patients is well after repair of "isolated ventricular inversion" and ventricular septal defect.

    Axial cineangiography in congenital heart disease. Section II. Specific lesions.
    Ovid Technologies (Wolters Kluwer Health) ; 1977

    Abstract: The value of axial cineangiography in several forms of congenital heart disease serves as an illustrated supplement to Section I. These techniques visualize defects in the entire ventricular and atrial septum. In persistent atrioventricular (A-V) canal, it is possible to visualize all parts of both septa, status of the A-V valves (two valves versus a common A-V valve), and if a common A-V valve, its degree of override. In tetralogy of Fallot, the bifurcation of the pulmonary trunk, entire ventricular septum and coronary arteries are vividly shown. The presence of true and confluent pulmonary arteries versus systemic or bronchial arteries in pseudotruncus is clearcut. In double outlet right ventricle or in transpositions with or without double outlet right ventricle, the mitral valve-semilunar valve relationships, the left ventricular outflow tract, subpulmonary region and a straddling tricuspid valve are well demonstrated. In asymmetric septal hypertrophy, biventricular angiography may be circumvented.

    Electrophysiological delineation of the specialized A-V conduction system in patients with corrected transposition of the great vessels and ventricular septal defect.

    Abstract: The specialized atrioventricular (A-V) conduction system was electrophysiologically delineated during open-heart surgery in four patients with congenitally corrected transposition of the great vessels and associated ventricular septal defect and one patient with single ventricle. Two consistent observations were made: 1) In no case was the specialized A-V conduction system found in the right atrium, whether or not there was a coronary sinus ostium present. 2) Specialized A-V conduction system electrograms were never delineated posterior to the ventricular septal defect, in contradistinction to this usual location in hearts having ventricular septal defects associated with other congenital lesions. In three of five patients, the initial course of the A-V conduction system of the ventricles was delineated between the anterior aspect of the ventricular septal defect and the pulmonary artery. In one patient the proximal portion of the A-V conduction system was delineated on the anterior aspect of the pulmonary conus. The course and extent of the A-V conduction system delineated in the morphological left ventricle suggests it is a left bundle branch. The surgical implications of the ectopic location of the A-V conduction system anterior to the ventricular septal defect, and the variability of the more proximal portion of the A-V conduction system are discussed.

    Axial cineangiography in congenital heart disease. Section I. Concept, technical and anatomic considerations.
    Ovid Technologies (Wolters Kluwer Health) ; 1977

    In: Circulation, Ovid Technologies (Wolters Kluwer Health), Vol. 56, No. 6 ( 1977-12), p. 1075-1083
    Abstract: Cineangiographic axial techniques were designed to overcome the limitations of conventional angiography in the diagnosis of congenital heart disease. Two basic patient (or equipment) maneuvers are involved; 1) long axis of the heart is aligned perpendicular to the X-ray beam, and 2) rotation of patient results in the heart being radiographically sectioned at 30 degree angles. To accomplish this with fixed vertical and horizontal X-ray tubes, three positions were developed: 1) "hepato-clavicular," "4 chamber," 2) "long axial oblique," 3) "anterior-posterior axial." A fourth, the "sitting-up" projection is discussed. The hepato-clavicular position profiles the posterior ventricular septum and atrial septum, separates the A-V valves, places the four cardiac chambers en face, and clarifies mitral valve-semilunar valve and outflow tract relationships. The long axial oblique profiles the anterior ventricular septum, left ventricular outflow tract, aortic valve-anterior mitral valve leaflet. The sitting-up view visualizes the bifurcation of the pulmonary trunk and separates true pulmonary arteries from systemic collaterals.

    Late survival and symptoms after repair of tetralogy of Fallot.

    In: Circulation, Ovid Technologies (Wolters Kluwer Health), Vol. 65, No. 2 ( 1982-02), p. 403-410
    Abstract: The long-term results of 414 patients who underwent repair of tetralogy of Fallot between 1967 and 1977 were studied and correlated with the results of others. There were nine late deaths (8-year actuarial survival 95.8%). Six of the deaths wee directly related to the malformation or its treatment. Eight patients (2.4%) required reoperation. Ten patients (4.8%) had arrhythmic symptoms. Eight (3.1%) had congestive heart failure that required treatment. The risk factors associated with late events of all types, including death, were: older age at repair, a high mean ratio of peak systolic right-to-left ventricular pressures (PLV/RV) immediately after repair, and the presence of a Potts anastomosis. Neither a transannular patch nor a previous Blalock-Taussig or Waterson anastomosis was an incremental risk factor. Bacterial endocarditis was not observed. Three hundred seven patients underwent repair primarily or after a single Blalock-Taussig or Waterston shunt and had a PRV/LV of 0.85 or less after repair. Among these selected patients, the actuarial survival was 98.1%, which is still lower than that for the general population (p = 0.12), and freedom from events was 95.9%. Late after repair, PRV/LV was lower by 6 +/- 28% (+/- SD) than PRV/LV immediately after repair (p = 0.03) in the 33 restudied patients with such data. The higher the PRV/LV immediately after repair, the greater the percent reduction.

    Ventricular and pulmonary artery volumes in patients with absent pulmonary valve. Factors affecting the natural course.

    In: Circulation, Ovid Technologies (Wolters Kluwer Health), Vol. 67, No. 1 ( 1983-01), p. 183-190
    Abstract: Right and left ventricular (RV and LV) volumes were determined in 19 patients with absent pulmonary valve syndrome using Simpson's rule and area-length methods. The volume of the proximal right pulmonary artery (RPAV) was calculated at maximal and minimal size using the area-length method. Patient groups included four newborns who responded to medical management (group 1A), seven critically ill newborns who died (group 1B), four infants ages 1-10 months (group 2) and four children ages 2-8 years (group 3). The RV end-diastolic volume in groups 1B and 2 was significantly greater than that in groups 1A and 3. The RV ejection fraction in groups 1B and 2 was significantly less than that in normal patients and groups 1A and 3. Maximal RPAV correlated well with RV stroke volume and end-diastolic volume. The maximal RPAV in group 1B was significantly greater than that in groups 1A and 3. Pulmonary arterial compliance was greater than normal in all groups, and the compliance in group 1B was more than two times that in the other groups. We conclude that the increased right pulmonary artery compliance and pulmonary regurgitation in patients with absent pulmonary valve contribute to bronchial obstruction and right-heart failure and are the causes of the high morbidity and mortality in these patients. The management should be directed to the alleviation of bronchial obstruction and right-heart failure.

    Abstract: An angiographic analysis of 10 cases of univentricular heart of the right ventricular type is reported. This congenital malformation is characterized by a large chamber with right ventricular morphology that receives both atrioventricular valves, and a second, smaller chamber, a trabecular pouch, with left ventricular morphology. These chambers are separated by a posterior septum but are connected by an inlet septal defect. The angiographic studies were done using the angled angiographic techniques in three patients and the standard frontal and lateral angiographic views in seven cases. The atrial situs in seven patients was solitus, in one inversus, and in two it was ambiguus with left isomerism. In seven patients the usually large right ventricular chamber received two atrioventricular valves and in four patients, one atrioventricular valve was straddling. Three patients had atresia of one atrioventricular valve. The trabecular pouch was small in seven patients but relatively large in three. In six patients the trabecular pouch was located posterior and to the left of the right ventricular chamber and in four anterior and to the right. Double outlet right ventricle was present in all cases. The aorta arose anteriorly to the pulmonary artery in nine patients and posteriorly in one. An autopsy was performed in one case and its correlation with the angiographic findings was remarkable. The angiographic demonstration of the anatomicaly details of this entity and its associated anomalies was facilitated by angled angiography.
