1/57. High origin of the right coronary artery with congenital heart disease.We encountered a case of anomalous high origin of the right coronary artery associated with ventricular septal defect and patent ductus arteriosus. The right coronary artery originated from the distal part of the ascending aorta resulting in unsuccessful induction of cardiac arrest by cardioplegia. We describe this rare case with anomalous origin of the right coronary artery.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/57. Thrombotic occlusion of the main stem of the left coronary artery in a neonate.Thrombotic coronary arterial occlusion, and myocardial infarction, are rare in the newborn. We report such a happening presenting shortly after birth with cardiogenic shock, no left ventricular output and a systemic circulation dependent on flow from a patent arterial duct.- - - - - - - - - - ranking = 0.77434791294685keywords = coronary, circulation (Clic here for more details about this article) |
3/57. Considerations in biventricular repair after the Norwood procedure.OBJECTIVE: The Norwood procedure can be applicable as a first stage palliation in children who can eventually undergo a biventricular repair. Although usual management of these patients is a primary neonatal repair, in selected patients staged approach with a Norwood procedure in the neonatal period followed by a Rastelli procedure in the infancy for conversion to two-ventricle physiology has been used alternatively. methods: We report our experiences on two infants who underwent a previous palliation with the Norwood procedure for lesions other than hypoplastic left heart syndrome and converted to two-ventricle physiology by the use of a Rastelli-type procedure. This report examines considerations in biventricular repair after the Norwood procedure especially need for ventricular septal defect enlargement and approach to placement of the right ventricle to pulmonary artery conduit. RESULTS: Both of the infants who underwent staged approach with an initial Norwood procedure for lesions other than hypoplastic left heart syndrome survived the operations and were clinically well at mid-term follow-up. CONCLUSION: In selected patients, the staged approach is an alternative in management of malformations other than hypoplastic left heart syndrome which share the important physiologic features of aortic outlet obstruction and ductal dependency of systemic circulation. We recommend routine enlargement of ventricular septal defect and proper positioning of the conduit at the time of subsequent biventricular repair.- - - - - - - - - - ranking = 0.060062198661132keywords = circulation (Clic here for more details about this article) |
4/57. 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 = 1.4285714285714keywords = coronary (Clic here for more details about this article) |
5/57. Ever heard of percutaneous transvenous selective coronary angiography? Unusual approach in a patient with patent ductus arteriosus.Arterial access for coronary angiography is usually achieved by the use of direct arterial puncture or, less frequently, by arterial cutdown. We present the case of a 39-year-old woman in whom a patent ductus arteriosus was used to enter the arterial system for left ventriculography, aortography, and selective coronary angiography. To our knowledge, this is the 1st reported case of selective coronary angiography with use of a transvenous approach.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
6/57. Patent ductus arteriozus associated with anomalous origin of the right coronary artery: a case report.Patent ductus arteriozus (PDA) is the most common type of extracardiac shunt and it usually closes within 2 or 3 days of birth, but it may remain patent for one's lifetime. In this paper, we report a 65-year-old woman with PDA associated with a right coronary arising anomaly. To our knowledge, the anomalous origin of the right coronary artery associated with PDA has not been published to date. In this case report, we used only the standard Judkins type of a left coronary catheter for cannulation of both left and right coronary arteries and as well as PDA.- - - - - - - - - - ranking = 1.1428571428571keywords = coronary (Clic here for more details about this article) |
7/57. Aberrant course of the left anterior descending coronary artery assoicated with anomalous left circumflex origin from the pulmonary artery.We have presented a two year nonoperative follow-up of an asymptomatic 14-year-old girl with an unusual anomaly of the coronary arteries. Systolic and diastolic murmurs heard preoperatively did not change following severance of a patent ductus arteriosus. Postoperative selective coronary arteriography revealed (1) anomalous orgin of the left anterior descending artery from the right aortic sinus of valsalva crossing between the aorta and pulmonary artery, (2) aberrant circumflex artery orgin from the pulmonary artery and (3) collaterals from the left anterior descending and right coronary arteries to the circumflex artery. This combination of coronary anomalies has never been described previously.- - - - - - - - - - ranking = 1.1428571428571keywords = coronary (Clic here for more details about this article) |
8/57. Coronary artery fistula: report of three cases.Three children are described with a right coronary artery fistula communicating with a right heart chamber. Each had a continuous murmur like that of a patent ductus arteriosus but situated at a lower level. aortography established the diagnosis and excluded any accompanying malformation. It is concluded that to prevent complications surgical treatment should be recommended.- - - - - - - - - - ranking = 0.14285714285714keywords = coronary (Clic here for more details about this article) |
9/57. Anomalous left coronary artery from the main pulmonary trunk: physiologic and clinical importance of its association with patent ductus arteriosus and pulmonary hypertension.Origin of the left main coronary artery from the pulmonary trunk is an extremely rare, fatal, but potentially treatable anomaly. Left ventricular perfusion with desaturated blood with low pressure from the pulmonary artery results in early death. Associated pulmonary hypertension can help to prevent ischemia. We present a four-month-old boy with this anomaly associated with patent ductus arteriosus and pulmonary hypertension.- - - - - - - - - - ranking = 0.71428571428571keywords = coronary (Clic here for more details about this article) |
10/57. Echocardiographic features of adult tetralogy of fallot with natural palliative correction by patent ductus arteriosus.A thirty-year-old man with the diagnosis of the tetralogy of fallot and patent ductus arteriosus was admitted to our hospital because of a syncope. He reported no previous symptoms. We diagnosed adult tetralogy of fallot, which included all four characteristic anomalies: ventricular septal defect, overriding aorta, pulmonary artery stenosis, and right ventricular hypertrophy. The associated persistent ductus arteriosus and the presence of compensatory arteriovenous communications produced a continuous flow load on the left ventricle, which resulted in moderate left ventricular hypertrophy, but without symptoms of pulmonary congestion or cardiac decompensation. Anatomic diagnosis and hemodynamic assessment were established by transthoracic and transesophageal echocardiography, with incidental finding of a quadricuspid aortic valve. To the best of our knowledge, our case of the adult form of Fallot's tetralogy associated with both patent ductus arteriosus and quadricuspid aortic valve is the first one ever described. It is well known that patients with tetralogy of fallot who do not undergo operation in childhood have short survival, which depends predominantly on the degree of pulmonary artery stenosis and early development of collateral circulation to the lungs. Long-term persistence of natural aortopulmonary anastomosis with systemic collateral circulation to the lungs and remodeling of the heart, with better hemodynamic balance as well as the presence of mild pulmonary artery stenosis probably enhanced the survival of our patient.- - - - - - - - - - ranking = 0.12012439732226keywords = circulation (Clic here for more details about this article) |
