1/88. A novel use of Amplatzer duct occluder.This report describes the use of the Amplatzer patent ductus arteriosus occluder to close a left ventricle to descending aorta conduit. The patient was a 10-year-old male who was born with critical aortic stenosis and left ventricular outflow tract obstruction. After initial valvotomy, he underwent left ventricular to descending aorta conduit placement. At the age of 10, he had a Konno procedure to enlarge the left ventricular outflow tract and 21-mm St. Jude aortic valve placement. Closure of the conduit was not addressed because it was inaccessable from median sternotomy. Postoperatively, echocardiogram revealed significant flow through the conduit with a wide pulse pressure. cardiac catheterization was performed with the premise to close the conduit with an Amplatzer patent ductus arteriosus occluder device.- - - - - - - - - - ranking = 1keywords = valve (Clic here for more details about this article) |
2/88. Transcatheter closure of a patent ductus arteriosus in an elderly patient with the Gianturco-Grifka vascular occlusion device.This paper reports the unusual case of a 76-year-old woman who was discovered to have a hemodynamically significant patent ductus arteriosus following uneventful mitral valve replacement, utilizing cardiopulmonary bypass. The shunt was successfully eliminated using a new transcatheter device, thereby obviating the need for further surgery. The patient did not have calcification within the ductus, making diagnosis prior to surgery more difficult.- - - - - - - - - - ranking = 1keywords = valve (Clic here for more details about this article) |
3/88. Current indications for left thoracotomy in coronary revascularization and valvular procedures.BACKGROUND: Left thoracotomy is infrequently used for cardiac procedures, but its application in reoperative and minimally invasive coronary revascularization and in valvular procedures has been reported recently. methods: Three case reports and a review of the current literature illustrate the unique benefits of this approach for myocardial revascularization and valve replacement. RESULTS: Reoperative coronary revascularization of the left anterior descending and circumflex coronary arteries was performed off-pump via a left posterolateral thoracotomy. For the second case, this approach was used for coronary artery bypass grafting of the right coronary and left anterior descending arteries with femoral-femoral cardiopulmonary bypass in a patient with congestive heart failure and coronary artery disease who also required closure of a patent ductus arteriosus. In the third case, mitral valve replacement using femoral venous and aortic cannulation for cardiopulmonary bypass was performed via a left thoracotomy to avoid a retrosternal gastric conduit in a patient with severe mitral stenosis and congestive heart failure. All patients returned to normal activity and are asymptomatic. CONCLUSIONS: These case reports and a comprehensive review of the literature demonstrate the utility of left thoracotomy as an alternative approach to standard median sternotomy in selected cases of revascularization and valvular procedures.- - - - - - - - - - ranking = 2keywords = valve (Clic here for more details about this article) |
4/88. Goldenhar's syndrome associated with cardiac malformations.A case of Goldenhar's syndrome associated with cardiac malformations such as single ventricle, atresia of pulmonary artery, and patent ductus arteriosus is described. The association of cardiac malformations with Goldenhar's syndrome is very rare and suggests that it is necessary to perform a careful clinical evaluation in this syndrome whether or not additional malformations may exist in visceral organs.- - - - - - - - - - ranking = 55.157060207005keywords = atresia (Clic here for more details about this article) |
5/88. Necrotizing tracheobronchitis in patent ductus arteriosus-dependent cyanotic congenital heart disease.We report 2 patients with necrotizing tracheobronchitis (NTB) associated with patent ductus arteriosus-dependent cyanotic congenital heart disease. The pathologic findings suggest that hypotension and decreased tracheo-bronchial perfusion were the major contributing factors in the development of NTB. Necrotizing tracheobronchitis developed in infants with pulmonary atresia and Ebstein's anomaly with pulmonary stenosis. Both infants required prostaglandin E1 infusion from early infancy, and presented with sudden onset of dyspnea and hypercapnea. In one infant, NTB developed prior to mechanical ventilation. In the other infant, NTB developed after 4 days of mechanical ventilation. Care of both infants involved minimal pressures and FiO(2), adequate humidification, and optimal temperature of inspired gases; these factors probably did not play a role in the development or worsening of NTB. Both infants had hypotension and hypoxemia. These factors could have contributed to the development of NTB because of decreased perfusion pressure and tissue hypoxia. As the area of necrosis and its severity correlated with the area of blood supply served by the specific feeding arteries, we speculate that tissue hypoperfusion was the major cause of NTB.- - - - - - - - - - ranking = 1362.141401787keywords = pulmonary atresia, atresia (Clic here for more details about this article) |
6/88. Unilateral CHARGE association.A case with a predominantly unilateral CHARGE association is reported. The CHARGE association refers to a combination of congenital malformations. This boy had left-sided anomalies consisting of choanal atresia, coloboma and peripheral facial palsy. The infant had a frontal encephalocele, an anomaly not included in the definitions of CHARGE association. CONCLUSION: even when anomalies are predominantly unilateral, the CHARGE association should be considered in the differential diagnosis.- - - - - - - - - - ranking = 55.157060207005keywords = atresia (Clic here for more details about this article) |
7/88. A new use for the amplatzer duct occluder device.We report a case in which the Amplatzer device for percutaneous occlusion of ductus arteriosus was successfully used for occluding a large systemic-pulmonary collateral vessel in a patient who had previously undergone surgery for correction of pulmonary atresia and ventricular septal defect (Rastelli technique), and was awaiting the change of a cardiac tube. In the first attempt, the device embolized to the distal pulmonary bed and, after being rescued with a Bitome, it was appropriately repositioned with no complications and with total occlusion of the vessel.- - - - - - - - - - ranking = 1362.141401787keywords = pulmonary atresia, atresia (Clic here for more details about this article) |
8/88. twins with oesophageal atresia and the CHARGE association.twins are rarely concordant for oesophageal atresia and tracheo-oesophageal fistula.

9/88. Surgical correction of aortic valve stenosis with persistent ductus arterious and servere pulmonary hypertension.This is a report of a case in which the unusual association of severe aortic valve stenosis with persistent ductus arteriosus complicated by severe pulmonary hypertension, was diagnosed and correction of the anatomical lesions carried out in one stage. Re-investigation after one year showed that the duct was closed, the pulmonary artery pressure was lower than before the operation and the gradient across the aortic valve reduced. A modern approach to treatment based on full cardiac assessment is stressed. Problems arising during the operation are discussed.- - - - - - - - - - ranking = 6keywords = valve (Clic here for more details about this article) |
10/88. Stenotic semilunar valve in persistent truncus arteriosus.The clinical, hemodynamic, and pathologic findings in two newborn infants with persistent truncus arteriosus and stenosis of the truncal valve are described. In one case the anatomic features of the basic condition were classic, with a dysplastic semilunar valve which was mainly stenotic and also incompetent, while in the other the truncus arteriosus arose exclusively from the right ventricle and was almost exclusively stenotic. A ventricular septal defect was the only outlet for the left ventricle. In this case, mitral stenosis was also present and associated with a left-to-right shunt at the atrial level.- - - - - - - - - - ranking = 6keywords = valve (Clic here for more details about this article) |
