1/316. Penetrating trauma to the tricuspid valve and ventricular septum: delayed repair.Penetrating cardiac trauma can result in a wide range of injuries to intracardiac structures. Missile injury, in particular, can cause damage in more than one cardiac chamber that may be difficult to identify at initial emergent operation. We report a case of late repair of traumatic ventricular septal defect and tricuspid valve perforation from gunshot wound. This case illustrates the importance of thorough examination of intracardiac anatomy during emergent and delayed repair for penetrating cardiac trauma.- - - - - - - - - - ranking = 1keywords = valve (Clic here for more details about this article) |
2/316. Complete atrioventricular septal defect and Ebstein's anomaly.A case child with complete atrioventricular septal defect (AVSD) and Ebstein's anomaly underwent surgical treatment at 3 months of age. She died on the third postoperative day. Postmortem examination showed complete AVSD, downward displacement of the right atrioventricular valve, left ventricular outflow tract obstruction, and hypertensive pulmonary vascular disease. association of complete AVSD and Ebstein's anomaly is a rare cardiac anomaly for which no attempt at surgical repair has previously been made. This report deals with our experience and also with the morphological features of this anomaly.- - - - - - - - - - ranking = 0.2keywords = valve (Clic here for more details about this article) |
3/316. Left ventricle to pulmonary artery conduit in treatment of transposition of great arteries, restrictive ventricular septal defect, and acquired pulmonary atresia.Progressive cyanosis after banding of the pulmonary artery in infancy occurred in a child with transposition of the great arteries and a ventricular septal defect, and a Blalock-Taussig shunt operation had to be performed. At the time of correction a segment of pulmonary artery between the left ventricle and the band was found to be completely occluded so that continuity between the left ventricle and the pulmonary artery could not be restored. A Rastelli type of operation was not feasible as the ventricular septal defect was sited low in the muscular septum. Therefore, in addition to Mustard's operation, a Dacron conduit was inserted from the left ventricle to the main pulmonary artery to relieve the obstruction. Postoperative cardiac catheterization with angiocardiography indicated a satisfactory haemodynamic result. The patient remains well 11 months after the operation. This operation, a left ventricle to pulmonary artery conduit, may be used as an alternative procedure in patients with transposition of the great arteries, intact interventricular septum, and obstruction to the left ventricular outflow, if the obstruction cannot be adequately relieved.- - - - - - - - - - ranking = 424.26890099467keywords = pulmonary atresia, atresia (Clic here for more details about this article) |
4/316. Atrioventricular septal defect with separate right and left atrioventricular valvar orifices in a patient with foetal hydantoin syndrome.The teratogenic properties of phenytoin, including cardiac malformations, have been previously documented. We report one patient with foetal hydantoin syndrome and atrioventricular septal defect with common atrioventricular junction but separate right and left atrioventricular valves, an association that has not been described, to the best of our knowledge.- - - - - - - - - - ranking = 0.2keywords = valve (Clic here for more details about this article) |
5/316. An unusual tethering of the bridging leaflets in atrioventricular septal defect producing a communication from left atrium to right ventricle.We describe a 39-year-old woman who was diagnosed as having an unusual atrioventricular septal defect with a communication from left atrium to right ventricle. A common atrioventricular junction, with partially separated right and left atrioventricular orifices, was found at transoesophageal ultrasonic examination. Both bridging leaflets were attached to the underside of the atrial septum, which was grossly malaligned relative to the ventricular septum. The shunt was exclusively from left atrium to right ventricle because of the overriding of the left atrioventricular valve, with the left component of the inferior bridging leaflet firmly fused to the ventricular septal crest.- - - - - - - - - - ranking = 0.2keywords = valve (Clic here for more details about this article) |
6/316. Arterial switch with internal pulmonary artery banding. A new palliation for TGA and VSD in complex cases.In most cases, one stage repair by arterial switch operation (ASO) is the optimal treatment for neonates with transposition of the great arteries (TGA). Nevertheless, a ventricular septal defect (VSD) associated with TGA remains a major risk factor for early death and reoperation after complete repair in neonates with complex anatomy. A new palliative approach for such specific cases is proposed. An internal pulmonary artery banding (IPAB), as that already used to palliate other cardiac malformations, is performed in association with ASO instead of VSD closure. At the end of ASO, a circular polytetrafluorethylene (PTFE) patch with a 4-mm central hole is oversewn into the neo-pulmonary trunk. We adopted this method in a 17-day-old boy with TGA, VSD, hypoplastic tricuspid valve and diminutive right ventricle. After the operation the child thrived and was doing well without medication. Satisfactory growth of the right ventricle and tricuspid valve was observed by echocardiography during the following months. The patient successfully underwent VSD closure and IPAB removal 2 years after the first procedure. ASO with IPAB could be appropriate in all forms of TGA and VSD in which VSD closure appears too challenging in the neonatal period and in patients with uncertain suitability for biventricular repair. We preferred to use IPAB instead of classic PAB in order to reduce the risk of pulmonary valve damage, pulmonary artery distortion, and above all pulmonary artery dilatation and related coronary compression. In the presented case the strategy as well as IPAB worked according to our expectations.- - - - - - - - - - ranking = 7.3448478937515keywords = pulmonary valve, valve (Clic here for more details about this article) |
7/316. 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.- - - - - - - - - - ranking = 106.06722524867keywords = pulmonary atresia, atresia (Clic here for more details about this article) |
8/316. 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.- - - - - - - - - - ranking = 531.33612624333keywords = pulmonary atresia, atresia, valve (Clic here for more details about this article) |
9/316. Interruption of the aortic arch in adults.The interruption of the aortic arch is a rare cardiac congenital disease; such patients may occasionally survive to adulthood without surgery. The associated intracardiac malformations may modify survival. Our aim is to report three young adults (18-19 years of age) with interruption of the aortic arch. Two had type C, and the other had type B with subpulmonic ventricular septal defect and pulmonary valve insufficiency. We review 106 cases collected from the medical literature into 3 groups: 1) the whole group of patients; 2) patients with isolated interruption of the aortic arch, and 3) patients with interruption of the aortic arch associated with ventricular septal defect. In the whole group we found 18 cases of interruption of the aortic arch type A, and 25 cases of interruption of the aortic arch type B; 37 cases of isolated interruption of the aortic arch and 43 cases associated with ventricular septal defect. Fifty percent of the patients died before 15 days of life (0.042 years). According to the cumulative frequency graphic, only 5% of the patients survived beyond the age of 5 years. We found no information to relate patient's survival rate and anatomic type of the interruption of the aortic arch. From adolescence, the survival of the patients with interruption of the aortic arch associated to septal ventricular defect was 7%, and a 14% survival was found in patients with isolated interruption of the aortic arch. No statistical difference was found between the means of the ages of these two groups (P > 0.25).- - - - - - - - - - ranking = 6.9448478937515keywords = pulmonary valve, valve (Clic here for more details about this article) |
10/316. thromboembolism originated from the pulmonary artery stump after Fontan operation.Cerebral thromboembolism is a rare but serious complication after Fontan operation. This is the report of a patient who underwent a successful intracardiac thrombectomy for cerebral thromboembolism after Fontan operation. A 2-year-old girl was referred to us with the diagnosis of tricuspid atresia without pulmonary stenosis, normally related great arteries, and a ventricular septal defect. Although she underwent a successful Fontan operation and division of the main pulmonary artery, she developed a cerebrovascular event at 3 weeks after the operation. echocardiography demonstrated a large thrombus within the residue of the main pulmonary artery, and suggested that the thrombus had migrated into the systemic circulation by way of the ventricular septal defect. At 2 weeks after the cerebrovascular event, she underwent thrombectomy and excision of the pulmonary valve. Although she has developed slight left-sided hemiparesis, she is leading a normal life at 1 year after the operation.- - - - - - - - - - ranking = 10.566803060539keywords = pulmonary valve, atresia, valve (Clic here for more details about this article) |
