1/192. Recognition of functional pulmonary atresia by color Doppler echocardiography.

    Vigorous crying aids right ventricular ejection into the pulmonary artery. This phenomenon can differentiate functional pulmonary atresia from anatomic pulmonary atresia. ( info)

2/192. Complex pulmonary atresia in an adult: natural history, unusual pathology and mode of death.

    A patient with unrepaired complex pulmonary atresia had a normal life, achieving two successful pregnancies, until the age of 44 years. Confluent central pulmonary arteries were supplied by a fistuious communication from the left coronary artery, and from other collateral arteries arising from the underside of the aortic arch. Unusual aneurysms were present. death at the age of 46 resulted from dissection and rupture of an aneurysmal dilation of the pulmonary trunk. ( info)

3/192. Right ventricular thrombosis early after bidirectional Glenn shunt.

    thrombosis in the right ventricle occurred early after bidirectional superior cavopulmonary shunt in 2 patients with pulmonary atresia with intact ventricular septum and major right ventricular coronary artery communication, and perioperative brain infarction occurred in 1 patient. Clinicians should be aware of the hazards of this potentially lethal complication, and transfusion of platelets and fresh plasma should be minimized. Although the hemodynamic state is good, echocardiography should be performed frequently and strict anticoagulation should be started as early as possible. ( info)

4/192. Combined Rastelli and atrial switch procedure: a 10-year follow-up.

    We performed a combined atrial (Mustard) and ventricular (Rastelli) repair on a previously palliated patient with situs inversus, atrioventricular discordance, ventricular septal defect, and pulmonary atresia. The suitability and durability of this operative strategy is supported by the satisfactory hemodynamic and functional status of the patient 10 years later. ( info)

5/192. Rapid two-stage repair of S,L,L, ventricular septal defect, pulmonary atresia, ebstein anomaly of the tricuspid valve, and stenotic pulmonary arteries.

    The repair of a corrected transposition of the great arteries, ventricular septal defect, and pulmonary atresia is presented. An ebstein anomaly of the tricuspid valve, dextrocardia, and severe distortion of the pulmonary arteries complicated the surgical procedure, which was performed in two stages. Reconstruction of the pulmonary arteries and a bidirectional cavopulmonary anastomosis were performed first; Rastelli and hemi-Mustard procedures completed the correction. The rationale and the possible indications of this "one and a half ventricle" repair are discussed. ( info)

6/192. Persistent pulmonary hypertension of the newborn associated with pulmonary atresia and intact interventricular septum.

    Neonates with pulmonary atresia and intact interventricular septum (PAIVS) do not have pulmonary vascular disease secondary to their heart abnormality. Persistent pulmonary hypertension of the newborn has not been described in association with this condition. The case is reported of a female neonate born with PAIVS, who preoperatively had no clinical evidence or any risk factors for persistent pulmonary hypertension of the newborn, but whose postoperative course was highly suggestive of persistent pulmonary hypertension; necropsy confirmed the features of pulmonary vascular disease.

7/192. The development of hypertrophic pyloric stenosis in a patient with prostaglandin-induced foveolar hyperplasia.

    BACKGROUND: Hypertrophic pyloric stenosis (HPS) has been described in association with several obstructive antropyloric lesions including idiopathic foveolar hyperplasia (gastric mucosal hypertrophy), feeding tubes, eosinophilic gastroenteritis, and hypertrophic antral polyps. Non obstructive antral webs have also been described with HPS. PATIENT AND methods: We present a case of gastric-outlet obstruction in association with HPS, namely, prostaglandin-induced foveolar hyperplasia. This entity has been previously described, but rarely in association with HPS. We report a female infant requiring prostaglandin therapy for pulmonary atresia who developed dose-related prostaglandin-induced foveolar hyperplasia and symptoms of progressive non-bilious vomiting. RESULTS: Initially, ultrasonography demonstrated evidence of antral mucosal hypertrophy as the cause for gastric-outlet obstruction. The patient subsequently developed progressive thickening of the antropyloric muscle, resulting in sonographic appearances of hypertrophic pyloric stenosis. Pyloromyotomy was eventually required for treatment of HPS. CONCLUSION: A common denominator of most of the above-described entities is thickening and/or hypertrophy of the antral mucosa. We suggest that the antropyloric musculature may hypertrophy in an effort to overcome the gastric-outlet obstruction caused by the adjacent thickened antral mucosa. In other words, these entities may represent examples of "secondary" hypertrophic pyloric stenosis. ( info)

8/192. cyanosis due to diastolic right-to-left shunting across a ventricular septal defect in a patient with repaired tetralogy of fallot and pulmonary atresia.

    cyanosis as a result of right-to-left shunting across a ventricular septal defect is commonly encountered in patients with congenital heart disease when systolic pressure in the right ventricle exceeds that in the left ventricle. Reported is the case of a child who remained cyanosed after surgical correction of pulmonary atresia despite right ventricular systolic pressure being lower than left ventricular pressure. Colour-flow Doppler showed a residual ventricular septal defect, with right-to-left shunting in diastole alone. ( info)

9/192. pulmonary atresia with intact ventricular septum, right-sided aortic arch, and an aorto-pulmonary collateral artery.

    Described is a rare association in a patient with the heart in the left chest, namely pulmonary atresia with intact ventricular septum, fistulous coronary arterial connections, a right-sided aortic arch and an aorto-pulmonary collateral artery feeding one lung. The pulmonary arteries were non-confluent, with the right lung supplied by the right arterial duct originating from the under surface of the right-sided aortic arch, and the left lung supplied through the aorto-pulmonary collateral artery arising from the descending aorta. The surgical management is different in the setting of non-confluent pulmonary arteries. ( info)

10/192. Pathologic finding of restenosis in stent-implemented right ventricle-pulmonary artery extracardiac conduit.

    We describe an excised specimen of a stent-implanted valved equine pericardial extracardiac conduit in the right heart. It appears from careful pathologic examination that the stent acted as a nidus for thrombus formation followed by thick neo-intimal development over the stent, which caused restenosis. Restenosis occurred despite anticoagulation. ( info)
