1/72. Development of rib notching after a cava-pulmonary anastomosis.A patient with tetralogy of fallot and mitral regurgitation developed unilateral rib notching on the right side secondary to a palliative cava-pulmonary anastomosis. After the operation, decreased perfusion of the right upper and middle lobes stimulated the development of collateral vessels from the systemic circulation to the right pulmonary artery. To our knowledge, this is the first time that this has been described.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
2/72. Left main coronary artery compression by aneurysmal pulmonary artery in a patient with tetralogy of fallot with absent pulmonary valve.We describe an 11-year-old girl with tetralogy of fallot and absent pulmonary valve, who on selective coronary angiography was found to have extrinsic compression of the left main coronary artery by the aneurysmally dilated pulmonary artery. This abnormality has not been reported previously.- - - - - - - - - - ranking = 72.873016270238keywords = coronary (Clic here for more details about this article) |
3/72. Anomalous origin of the left coronary artery in tetralogy of fallot associated with abnormal mitral valve pathology.The association of anomalous left coronary artery with congenital heart disease is a rare occurrence. Seven cases of anomalous left coronary artery associated with tetralogy of fallot have been reported in the literature. We report a unique case with severe mitral valve abnormality that precluded standard surgical repair.- - - - - - - - - - ranking = 72.873016270238keywords = coronary (Clic here for more details about this article) |
4/72. Isolated origin of the left subclavian artery from the left pulmonary artery.We describe two children with isolated origin of the left subclavian artery from the left pulmonary artery detected by echocardiography during the assessment of their congenital cardiac malformations. Both patients demonstrated pre-operative evidence of subclavian steal. This entity results from persistence of the dorsal segment of the sixth left arch, with regression of the left fourth arch and interruption of the left dorsal arch distal to the origin of the seventh left intersegmental artery. The significance of this finding relates to the potential for pulmonary overcirculation, which could have significant post-operative ramifications if not detected prior to surgical repair of an associated cardiac malformation. This entity differs from cases with a right aortic arch and aberrant left subclavian artery which has the potential to form a vascular ring, unlike cases with isolated origin of the left subclavian artery from the pulmonary artery that do not cause compression of the airway.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
5/72. Recanalization of an occluded modified Blalock-Taussig shunt by balloon angioplasty within 12 hours of its construction.An infant developed severe desaturation within a few hours of construction of a modified Blalock-Taussig shunt. echocardiography revealed that the shunt had become occluded, and this was confirmed angiographically. At catheterisation, therefore, we passed a 0.014" percutaneous transluminal coronary angioplasty wire through the occluded shunt into the right pulmonary artery and then dilated the shunt successfully using a 5 mm coronary angioplasty balloon. Six weeks later, the shunt remained patent.- - - - - - - - - - ranking = 24.291005423413keywords = coronary (Clic here for more details about this article) |
6/72. lead configuration for defibrillator implantation in a patient with congenital heart disease and a mechanical prosthetic tricuspid valve.The authors devised a nonthoracotomy defibrillation system for a patient with a prosthetic tricuspid valve using existing technology and previously established implantation techniques. Their lead configuration deviates substantially from existing designs in its primary use of a coronary sinus defibrillation coil and a left-sided subcutaneous array to distribute current across the ventricular myocardium.- - - - - - - - - - ranking = 12.145502711706keywords = coronary (Clic here for more details about this article) |
7/72. tetralogy of fallot: an overview, case report, and discussion of dental implications.tetralogy of fallot (TOF) is the most common cause of cyanotic heart disease. The anatomic defects comprising TOF lead to the systemic circulation of oxygen-poor (desaturated) blood, resulting in symptoms of cyanosis, polycythemia, and hypoxia. Untreated, most patients with this disorder die during childhood. Surgical treatment aimed at correcting the defects is currently recommended for infants. Long-term studies have reported good results with this approach. The case history of a four-year-old male with uncorrected tetralogy of fallot is presented. The patient required extensive dental treatment prior to scheduled cardiac catheterization. The dental findings and plan of care for this patient are detailed, and attention is given to the role of the medical work-up, preoperative antibiotics, and sedatives. It is stressed that the dental treatment plan for patients with tetralogy of fallot must take into account the patients' medical status both prior to and following corrective surgical procedures.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
8/72. Biventricular pacing for successful weaning from extracorporal circulation in an infant with complex tetralogy of fallot.Biventricular pacing therapy is an innovative therapy for improving cardiac output in adult patients with severe heart failure. However, this technique is not yet used in infants with congenital heart disease. We present a six month old infant with tetralogy of fallot and atresia of the left pulmonary artery in which biventricular stimulation led to improved left ventricular function and successful weaning from extracorporeal circulation.- - - - - - - - - - ranking = 5keywords = circulation (Clic here for more details about this article) |
9/72. A method of outflow tract reconstruction in tetralogy of fallot with anomalous anterior descending coronary artery.An anomalous anterior descending coronary artery that arises from the right coronary and crosses the right ventricle outflow tract can compromise corrective operations for tetralogy of fallot. The only safe method of outflow tract reconstruction reported until now is the use of a tubular graft from the right ventricle to the pulmonary artery. We report successful reconstruction of the outflow tract by placing a standard fabric path under the mobilized anomalous coronary artery. This technique should avoid the late complications of tubular conduits by preserving the natural posterior wall of the outflow tract for growth.- - - - - - - - - - ranking = 85.018518981944keywords = coronary (Clic here for more details about this article) |
10/72. Rastelli type repair using Freestyle valved conduit for a 69-year-old woman with tetralogy of fallot.A 69-year-old woman visited our hospital with general fatigue and shortness of breath on effort as the chief complaints. She was diagnosed as having tetralogy of fallot, using cardiac ultrasonography. The cardiac catheterization findings showed that right venticular hypertension was at 114/5 mmHg, which was parallel to the left ventricular pressure, and a pressure gradient of about 100 mmHg was observed between the right ventricle and the pulmonary artery. Coronary artery angiography revealed that the left coronary artery was intact, but the right had an abnormal origin from the left valsalva sinus and was estimated at nearly equal to the single coronary. Therefore, we performed a Rastelli type operation with a valved conduit which we made using a composite Hemashield artificial graft (diameter 20 mm) and Freestyle valve (diameter 21 mm). The postoperative course was uneventful and she was discharged with hemodynamic conditions mostly normalized.- - - - - - - - - - ranking = 24.291005423413keywords = coronary (Clic here for more details about this article) |
