[Intralobar sequestration causing heart failure in a new born infant. Surgical correction].

The authors report the occurrence of an intralobar pulmonary sequestration in a neonate with symptoms of congestive heart failure, due to a fistula effect in the sequestrated area. The venous drainage was directed mainly to the superior caval vein via azygos vein and accessorily to the left atrium. The patient became asymptomatic after lobectomy performed at the age of 11 days.

Precocity of pulmonary vascular obstruction of Down's syndrome.

Studying the pulmonary vascular resistance in children with ventricular septal and endocardial cushion defects, the authors found a statistically significant earlier and more severe reaction in children with Down's syndrome as compared to normals. Cardiac investigations with regard to surgical intervention should be made early in life, if the parents wish their child with Down's syndrome to undergo surgery.

Surgical repair of coarctation of the aorta in infants under one year of age. Long-term results in 146 patients comparing subclavian flap angioplasty and modified end-to-end anastomosis.

Between July 1976 and February 1991, 146 consecutive infants underwent surgical repair of coarctation of the aorta. Age at operation varied from 2 days to 11 months (median 1 month). Ninety-two (63%) were less than 2 months. Isolated coarctation was present in 65 patients (group 1), associated ventricular septal defect in 49 patients (group 2) and complex anomalies in 32 patients (group 3). The majority (65%) were in a critical condition and 45 patients (31%) were artificially ventilated. Subclavian flap angioplasty was performed in 39 patients and resection and end to end anastomosis in 107 patients. Neither hospital mortality was significantly different between subclavian flap angioplasty (15%) and end-to-end anastomosis (18%) nor was the postoperative hypertension. Actuarial survival at 10 years were 100% for group 1, 94% for group 2, and 62% for group 3. Seventeen patients had recurrent coarctation. No significant difference was found in terms of types of repair or age at operation. As no major advantage in terms of mortality and morbidity to either technique was found, we recommend resection and end-to-end anastomosis. This technique not only relieves the obstruction whatever the level is but also eliminates the ductal tissue, preserves the subclavian artery and avoids the use of prosthetic material.

Surgical treatment of subvalvular aortic stenosis. Long-term results.

From 1966 till May 1988, 53 patients underwent surgery for fixed subaortic stenosis. Subvalvular obstruction was isolated in 27 patients (Group I) and associated with aortic valve lesions in 26 (Group II). A membranous stricture was documented in 5 patients and a fibromuscular ring in 48. Excision of the ring and myectomy were performed in all patients, and an associated aortic valve replacement or reconstruction in 7 and 4 patients respectively. There were no hospital deaths. Follow-up evaluation in 50 patients ranged from 6 months to 22 years. Eight patients had to be reoperated upon (1 from group I, 7 from group II): aorto-ventriculoplasty was performed in 3, aortic valve replacement with redo myectomy in 3 and mitro-aortic valve replacement in 2. One of them had 2 reoperations. Functional status at the time of the last outpatient visit was most satisfactory. Continued evaluation remains necessary as obstruction may reappear despite the absence of symptoms.
