“…As pointed out by Dische and others [2][3][4][5][6][7], the cardiovascular anomalies associated with a horseshoe lung tend to embrace the spectrum of malformations seen in the "scimitar" syndrome [8- 1 2]. To the present time, there are about seven well described cases of horseshoe lung.…”

Case MaterialWe identified five patients at the Hospital for Sick Children in Toronto with the horseshoe lung anomaly and reviewed their chest radiographs, angiographic studies in four patients, and pathologic material in four patients, including a postmortem bronchogram in one patient.The diagnosis of horseshoe lung anomaly was made from pulmonary angiography in four patients and confirmed at autopsy in three of these, from pulmonary angiography alone in one patient, and from autopsy findings alone in one patient. Four of the five patients became symptomatic in the neonatal period. One of these had complex congenital heart disease with hypoplastic left heart syndrome, severe coarctation of the descending aorta, and double-outlet right ventricle and died in the neonatal period. The four other patients had features of scimitar syndrome. Three of these presented in early infancy with respiratory distress, believed to be at least partly secondary to congestive heart failure, and died in the first few months of life. The fifth patient, who also had features of the scimitar spectrum, was asymptomatic and was investigated angiographically after a chest radiograph showed dextrocardia, small right lung, and abnormal pulmonary vascular markings. She has subsequently remained asymptomatic.Seven additional patients with horseshoe lung anomaly have been reported in the world literature [1-6].

“…In a previous anatomical study we found aortic arch anomalies in 35% of hearts with transposition of the great arteries and right ventricular outflow tract obstruction.9 It should be noted that the diagnosis of right ventricular outflow tract obstruction is an estimation, and in that as well as in the present study it means an obstruction relative to normal. In this respect it is important to realise that in only a few patients with an obvious, angiocardiographically demonstrated, narrow subaortic area may a pressure gradient be recorded across it.491 5 Nevertheless, a poorly expanded or relatively narrow subaortic conus should be viewed as potentially obstructive according to Freedom et al 15 In our view more studies of the relation between anatomical right ventricular obstructions and catheterisation data are needed to establish the functional implications and natural history of these anomalies.…”

Of 279 patients with transposition of the great arteries, 14(5%) had narrowing of the aorta, including local coarctation (6), isthmus hypoplasia (6), isthmus atresia (1), and kinking of the aorta (1). There were six deaths in 10 surgically treated patients; in addition four patients died before operation. Two of the four survivors had a subpulmonary malalignment ventricular septal defect with angiocardiographic narrowing of the right ventricular outflow tract, two had evidence of redundant muscle tissue obstructing the right ventricular outflow tract. Necropsy showed the presence of anatomical right ventricular outflow tract or inflow tract obstruction or both in all 10 cases. Outflow tract obstruction was represented by anterior displacement of the infundibular septum and ventriculoinfundibular fold (in hearts with a subpulmonary malalignment ventricular septal defect) or by redundant muscle tissue; inflow tract obstruction was represented by hypoplasia of the tricuspid valve. It is concluded that the combination of transposition of the great arteries and narrowing of the aorta is always accompanied by right ventricular outflow or inflow tract obstruction or both; the right ventricular abnormalities are probably responsible for the presence of the aortic arch anomalies by reducing aortic flow during morphogenesis. Successful surgical treatment of this complex anomaly is feasible in selected cases.

“…73-9o,i55,i56 ventricular septal defect in any of these hearts can be sealed, resulting in subaortic atresia, or huge, with virtually no potential for spontaneous reduction or diminution in size. 74 ' 75 All dimensions between these extremes have been seen. In some patients, often newborns or neonates, with an associated obstructive anomaly of the aortic arch, the ventricular septal defect is intrinsically and unequivocally small.…”

nurtured this interest and became my mentors. I remember so well the reading list they suggested to provide a firm and solid background in paediatric cardiovascular medicine: Helen Taussig's two volume text 1 (Fig. 1); Alexander Nadas' Pediatric Cardiology 2 (Fig. 2); and the book emanating from the Karolinska Institute, of which Edgar Mannheimer was a co-editor 3 (Fig. 3). I devoured those wonderful books, savoring the clinical descriptions. I was particularly intrigued even then by the wonderful angiography displayed in the text from the Karolinska Institute. A senior member of the Department of Pathology at Los Angeles, Dr. Harrison Latta, was my immediate supervisor when I decided to devote a year's study while still a medical student to pediatric cardiovascular pathology. After performing an autopsy on a baby with complex and mystifying congenital heart disease, Dr. Latta suggested that I write Dr. Jesse Edwards for his opinion. That was the beginning of a friendship extending over more than 30 years with one of the signal contributors to our understanding of the
