Coarctation of the Aorta Associated with a Defect of the Muscular Portion of the Interventricular Septum in an Infant

Author and Disclosure Information

Abstract

THE association of coarctation of the aorta and a defect of the muscular portion of the interventricular septum has been infrequently reported. Bennetz1 noted the case of a four-month-old infant who had coarctation of the aorta, patent ductus arteriosus, and large multiple defects of the interventricular septum. Abbott2 in her review of 200 cases of coarctation of the aorta (adult type) found only one case associated with an interventricular septal defect located in the membranous portion.

Calodney and Carson3 in their study of 22 cases of coarctation of the aorta in infants had necropsy reports for 21. Of those 21, 9 infants, all having coarctations of infantile type, had associated interventricular septal defects of unstated sites. Most of the nine infants also had other major defects. We are presenting the clinicopathologic findings in an infant who had coarctation of the aorta (adult type) and a defect of the muscular portion of the interventricular septum.

CASE REPORT

Clinical Features

A 17-week-old boy was admitted to the hospital for cardiac evaluation. He had been a full-term infant weighing seven pounds. No initial respiratory distress had been noted. When he was two weeks old he was taken to the family physician because of impetigo and lack of appetite. At that time respirations were observed to be shallow; no murmur was heard.

When the infant was eight weeks old, he became colicky and respirations appeared to be labored. A roentgenogram of the chest showed a slightly enlarged heart and a large thymus. Roentgen therapy. . .
