[Exclusive approach through the pulmonary artery or r. atrium in the surgical treatment of stenoses of the r. ventricle ejection channel (author's transl)].

In the light of their experience of surgical treatment of right ventricle muscular stenoses, the authors have gradually abandoned the classical approach (ventriculotomy) and now exclusively use a new one through the tricuspid and pulmonary rings. The new approach considerably reduces the number and extent of enlargement patches in the infundibulum and should result in better preservation of the right ventricular function.

Reoperation for massively calcified pulmonary valve heterografts. Surgical considerations.

Calcifications of pulmonary valve heterografts inserted in children are more frequently recognized with increasing follow-up periods and may lead to reoperation. This complication is common with our non-industrially prepared procine valves and may also be observed with Hancock porcine heterografts. Reoperation is rendered difficult by incrustation of the massively calcified heterograft into the posterior aspect of the sternum and because of the need of adequate exposure of the pulmonary bifurcation. Four patients were successfully reoperated on by the authors. The valves were not replaced. An improved surgical technique used in the last three cases is described.

Long segment coarctation of the thoracic aorta in a young adult. An alternative treatment.

To avoid using an interposition Dacron graft in a 17-year-old female for repair of a long segment coarctation of the aorta, the authors combined reconstructing the thoracic aorta using a left subclavian arterial flap, and reimplanting the distal segment of the subclavian artery into the left carotid artery. coarctation repair was done through a left side thoracotomy and the subclavian artery reimplantation via a short vertical cervicotomy. This operation restores a practically normal anatomy without the inconvenience of the long-term hazards due to using prosthetic material.

[Left superior vena cava simulating abnormal pulmonary venous return].

The case of a seven year old boy with coarctation of the aorta and a left superior vena cava (SVC) draining into the left atrium is reported. Usually, in this condition the circulation is centripedal, descending from the left SVC to the left atrium and leading to systemic cyanosis or desaturation. In this case, the circulation was centrifugal and ascending from the left atrium to the left SVC to the innominate vein, leading to a left-to-right shunt as in abnormal pulmonary venous return. The left-to-right shunt flow was 4.2 l/mn and the ratio of pulmonary to systemic flow was 1.8: there was no pulmonary hypertension. This type of circulation is very rare and only two other cases were found in the literature. It may be explained by the proximity of the left pulmonary veins to the left SVC and by a functional mitral obstacle due to the increased pulmonary return. Simultaneous correction of the coarctation and ligature of the left SVC was carried out by left thoracotomy without cardiopulmonary bypass.

Tetralogy of Fallot with type C complete atrioventricular canal: surgical repair in three cases.

The successful repair of three consecutive cases of tetralogy of Fallot associated with complete atrioventricular canal type C is reported. The correct preoperative diagnosis was established by right and left ventriculography. Operative repair in the first two patients involved division of both hemivalves above the crest of the ventricular septal defect and closure of the septal defects with a single large Dacron patch. In the third patient, the septal defects were closed with two separate patches. The undivided hemivalves were attached to the patches by interrupted sutures placed more to the right side of the midline, so that tricuspid tissue was used to reconstitute the mitral valve. Right ventricular outflow tract obstruction was relieved by infundibulectomy, pulmonary valvulotomy, and placement of a Darcon patch on the infundibulum in Cases 1 and 3. A valved tube was used in Case 2. Six months postoperatively, the condition of the patient is satisfactory. The first patient is receiving digitalis; the second, digitalis and diuretics; and the third patient is well without treatment.

[Myasthenia gravis and thymectomy in a 2 year old girl (author's transl)].

The case of a 2 year old girl with myasthenia gravis is reported. Immunological investigations did not show any major abnormalities of the thymocytes. High levels of acetylcholine receptor antibodies were present before thymectomy. After surgery they decreased significantly and there was a clear clinical improvement.

[One stage repair of VSD in infants (author's transl)].

Concerning their experience between February 1973 and May 1979 about 258 infants less than 12 Kg operated up for large VSD, the authors studies the 27 deaths. Their is not statistical difference between patients under 6 Kg of weight (128 cases, 15 deaths) and patients over 6 Kg of weight (130 cases, 11 deaths). The procedure is performed under hypothermia and circulatory arrest under 5 Kg and moderate hypothermia with cardioplegic myocardial protection in other cases. The causes of deaths have been: --either post-op. complications (post-operative bleeding, catheter complication, mediastinitis), --or pre-operative error (Swiss cheese VSD, single ventricle). The indications for pulmonary artery banding remain multiples VSD, and VSD associated with other visceral malformations.
