Reconstruction of stenotic or nonconfluent pulmonary arteries simultaneously with a Blalock-Taussig shunt.

Stenosis or discontinuity of the pulmonary arteries associated with congenital cardiac defects was repaired in 12 patients, in conjunction with the Blalock-Taussig shunt. This approach was based on the following concepts: (1) The shunted blood is more uniformly distributed to both lungs, which avoids predominance of flow to the ipsilateral lung and long-term pulmonary vascular damage; (2) because adequate blood flow is maintained, the contralateral lung growth will be near normal; (3) the possibility of future surgical correction is enhanced. The ages of the patients ranged from 2 to 24 months. Five had a primary diagnosis of tetralogy of Fallot, three had double outlet of the right ventricle, three had single ventricle, and one had a truncus type anomaly. All operations were performed without cardiopulmonary bypass. Dilation of the stenotic segment was performed in two patients, enlargement of the stenotic segment in three, and resection of the segment and end-to-end anastomosis in four. Nonconfluent pulmonary arteries were corrected in three patients. In one, the stenotic segment was resected and an anastomosis was made between the left pulmonary artery and pulmonary trunk. In another patient, a segment of the right subclavian artery was interposed between the pulmonary trunk and intrahilar left pulmonary artery. In the third patient, the right pulmonary artery was disconnected from the aorta and a tube was interposed between the right and left pulmonary arteries. There were no intraoperative or late deaths, and postoperative angiographic evaluations were satisfactory. We believe that in infants needing a Blalock-Taussig shunt the pulmonary artery anomalies, if present, should be corrected simultaneously.

Echocardiographic routine analysis of the coronary sinus by an apical view: normal and abnormal features.

The echocardiographic aspects of the coronary sinus have not received much attention in the literature. In the few published articles about anomalous venous connection to the coronary sinus, the parasternal long axis view has been suggested as ideal for its visualization. More recently, it has been suggested that the coronary sinus in normal hearts is best visualized from the apical transducer position. The purpose of this study was to assess the appearance of the coronary sinus from an apical view in a group of 400 consecutive patients with ages varying from 5 days to 80 years. In ten patients with persistent left superior vena cava, the coronary sinus was markedly dilated throughout its extension. All cases were confirmed either by angiography or surgery. In another three patients with Ebstein's anomaly studied postoperatively, it was observed that the coronary sinus was abnormally draining into the right ventricle below the prosthesis plane. These findings were confirmed by the surgical reports. The routine evaluation of the coronary sinus was better performed by an apical view, which provided detailed information not only of normal, but also abnormal anatomy of this segment of the heart. We speculate that it could be especially useful in diagnosing coronary sinus atresia and thrombosis, and coronary ostium atresia, as well as total anomalous intracardiac pulmonary venous drainage.

Cross-sectional echocardiographic features of "absent" pulmonary valve. Report of two cases.

"Absence" of the pulmonary valve was recognized by cross-sectional echocardiography in two infants having relatively atypical clinical manifestations for this cardiac malformation. Both had associated lesions: tetralogy of Fallot and ventricular septal defect, respectively, which were also detected by this non-invasive technique. The findings which strongly suggested the diagnosis were the presence of a ridge of rudimentary pulmonary valvular tissue at the level of the pulmonary annulus and the aneurysmal dilation of the pulmonary arteries. The short axis view at the level of the great arteries was the best approach for visualization of these anatomical abnormalities. The parasternal long axis and sub-costal four-chamber views were also helpful in detecting the associated lesions. In both cases the diagnoses were confirmed at autopsy.
