Comparison of two regression lines over a finite interval.

The likelihood ratio test is presented for testing the equality of two regression lines versus the ordered alternative that Line 1 lies above Line 2 on a prescribed finite interval of values of the independent variable. Homoscedastic normal errors are assumed. An application is discussed and data from it are used to illustrate the methodology. A table of exact critical values is presented for alpha = .01, .05 and .10 for various degrees of freedom. Power comparisons are made with competing tests.

Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum.

Five cases of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum, with or without Kommerell's diverticulum, are presented. Either right or left thoracotomy with divesion of the aberrant retroesophageal left subclavian artery can be accomplished with good results. However, a right thoracotomy is recommended in the presence of a large Kommerell diverticulum because such a diverticulum should be excised. The development of a subclavian steal syndrome later in life may be prevented by reimplantation of the divided left subclavian artery into the aorta or the left common carotid artery.

Cyanosis in a patient with combined ostium primum and secundum atial septal defects and anomalous inferior vena cava with azygos continuation. Case report and surgical considerations.

A case is described of combined ostium primum and ostium secundum atrial septal defects and azygos connection of the inferior vena cava plus cyanosis. Emphasis is made to recognize the functional mechanism of cyanosis and to demonstrate the anatomic site of hepatic venous drainage so that an appropriate corrective operative procedure can be planned. A gratifying result was achieved in this case after closure of the atrial septal defects.

Total correction of double-outlet ventricle with concordant atrioventricular relation, dextrocardia, pulmonary stenosis, and situs inversus.

A case of successful surgical correction of double-outlet right ventricle with concordant atrioventricular relation, pulmonic stenosis, and situs inversus is described. Transposition of the great vessels was not present. Intracardiac repair with a Teflon tunnel conduit gave an excellent result. Proper resection of the subpulmonic obstructing fibromuscular band required no patch reconstruction of the outflow tract.
