Unilateral absence of pulmonary artery: a report on 19 selected clinical cases.

Nineteen cases of unilateral absence of the pulmonary artery (UAPA) were found in a group of 2,960 patients investigated consecutively by cardiac catheterization, angiocardiography, and pulmonary perfusion scintigraphy. The incidence of UAPA was 0,6%. In 8 cases (40%) UAPA was found in isolation, and in 11 cases (60%) it was combined with other congenital heart defects (CHD). In 30% of our patients the diagnosis of UAPA was suggested by clinical symptoms and plain chest X-ray. Pulmonary perfusion scan was made in 2,600 children before catheterization. Though it can provide strong evidence of the diagnosis, this should be confirmed by cardiac catheterization and selective angiography. Eight patients were operated upon. Systemic-pulmonary shunt operations were performed in 6, and ligation of PDA in 2 patients. In one of the latter severe hemoptysis occurred following ligation of the PDA. The pathophysiological and diagnostic aspects of UAPA are discussed.

[Anomalous left coronary artery originating from the pulmonary artery in infants].

The authors report on examples of surgical treatment of the left coronary artery originating from the pulmonary artery with myocardial infarction to be found in 4 infants and one suckling at the age of 2, 3, 6, 8, and 30 months. The anomalous origin of the left coronary artery from the pulmonary artery was double ligated. All children survived the operation and two years after the operation they were in good health and without complaints. Electrocardiographic signs of anterolateral ischaemia of the myocardium have decreased.

Clinical findings and hemodynamic parameters in adults surgically treated for coarctation of the aorta in childhood.

75 patients who had been operated between the ages of 3 and 17 years for juxta- or postductal coarctation of the aorta were investigated 11.2 years (1-19) later, when they had reached the mean age of 22 years. In 10 patients (13%) there had been an associated cardiac defect. Of the 65 patients without cardiac complications, 10% showed normal physiological values and 64% showed satisfactory results of surgery. There was moderate hypertension in 18% of the patients and in 6 (10%) there was a pressure gradient between the upper and lower extremities greater than 15 mm Hg. Aortography revealed recoarctation in only 3 cases (5%). The electrocardiogram was abnormal in 48% of the patients. Chest films showed the presence of specific and nonspecific signs of coarctation in 89% of the cases. Hemodynamic investigation by radiocirculography showed normal values in most instances.

Range-gated pulsed Doppler echocardiographic diagnosis of supracardiac total anomalous pulmonary venous drainage.

Three patients with total anomalous pulmonary venous drainage (TAPVD) into the innominate vein were studied by using M-mode and pulsed Doppler echocardiography. An abnormal continuous flow towards the transducer in a suprasternal notch position detected by pulsed Doppler echocardiography in the left hemithorax leftward of the aortic echo is a sign of blood flow through the left vertical vein into the innominate vein. This finding is highly specific for TAPVD. High-velocity flow across the tricuspid valve, disturbed flow in the right pulmonary artery and abnormal flow in the left atrium are additional important pulsed Doppler echocardiographic findings in TAPVD. Right ventricular enlargement and paradoxical interventricular septal motion by M-mode echocardiography were not specific enough to distinguish TAPVD from other right ventricular volume overload lesions. An echo-free space posterior to the left atrium was not recorded.
