1/26. Right ventricular myocardial bridge in a patient with pulmonary hypertension--a case report.Myocardial bridge is a not uncommon finding in routine diagnostic coronary angiography or pathological examination of the heart. It is almost always confined to the left ventricle and the left anterior descending coronary artery. This report describes a patient with chronic lung disease, severe left ventricular dysfunction, and pulmonary hypertension in whom coronary angiography revealed bridging of the right ventricular branch of the right coronary artery.- - - - - - - - - - ranking = 1keywords = ventricular dysfunction, left ventricular dysfunction, dysfunction (Clic here for more details about this article) |
2/26. Anomalous origin of the right coronary artery from the pulmonary artery and mitral regurgitation in a newborn.Anomalous origin of the right coronary artery (RCA) from the pulmonary artery (PA) is a rare congenital anomaly, and only 28 cases have been reported in the pediatric age group. We describe the case of an infant who had progressive mitral regurgitation and papillary muscle dysfunction in association with anomalous origin of the RCA from the PA. The diagnosis was made by color flow Doppler, confirmed by angiography, and the case was successfully corrected by reimplantation of the anomalous RCA to the aorta. This is only the second case of anomalous origin of the RCA from the PA diagnosed in infancy without an associated congenital anomaly of the heart and great vessels.- - - - - - - - - - ranking = 0.0014687760241546keywords = dysfunction (Clic here for more details about this article) |
3/26. A case of coronary artery fistula draining into the pericardium causing hematoma.A 28-yr old female patient admitted to our clinic because of dyspnea and chest pain. Her transesophageal echocardiography demonstrated a huge mass on the anterolateral wall of the left ventricle causing dysfunction of the myocardium. coronary angiography demonstrated left anterior descending artery fistula draining into the pericardial cystic mass. Hydatic cyst was suspected and ELISA and hemagglutinin tests were both negative for echinococcus granulosus. Magnetic resonance image of the heart showed a mass thought to be a hematoma inside the cyst. She underwent surgery. The cystic lesion with a pure hematoma inside, was excised, and the fistula between left anterior descending artery and the mass was ligated without any complications. To our knowledge, this is the first case of a pericardial hematoma due to a coronary artery fistula, in the English literature.- - - - - - - - - - ranking = 0.0014687760241546keywords = dysfunction (Clic here for more details about this article) |
4/26. Single coronary artery and sick sinus syndrome.We report 2 patients with recurrent syncope and dizziness, later noted to have single coronary arteries. Both had right heart strain, one having pulmonary hypertension and the other having right ventricular outflow obstruction, which resulted in sinus node dysfunction. patients were refractory to medical therapy and improved after pacemaker implantation.- - - - - - - - - - ranking = 0.0014687760241546keywords = dysfunction (Clic here for more details about this article) |
5/26. Biventricular repair for pulmonary atresia with intact ventricular septum associated with sinusoidal communications.pulmonary atresia with intact ventricular septum (PA-IVS) is very difficult to treat due to the variety of right ventricular hypoplasia and coronary artery anomalies. Biventricular repair is viewed as possible in patients with mild right ventricular hypoplasia but not in those with severe right ventricular hypoplasia or with sinusoidal communication. We report a case of a 17-day-old boy with PA-IVS and severe right ventricular hypoplasia and large sinusoidal communications. We successfully conducted biventricular repair, ligated coronary artery and right ventricular fistulas, and implemented right ventricular outflow tract reconstruction. He now enjoys good health and attends elementary school. Sinusoidal communications are not always a limiting factor in biventricular repair for PA-IVS if the right ventricle can be decompressed without inviting ventricular dysfunction by ligating fistulas.- - - - - - - - - - ranking = 0.69503268981186keywords = ventricular dysfunction, dysfunction (Clic here for more details about this article) |
6/26. Uncommon presentation and surgical correction of unroofed coronary sinus syndrome.A 59-year-old man with signs and symptoms of congestive heart failure, occurring a few months after an infective episode, underwent cardiac investigations revealing severe biventricular dysfunction, persistent left superior vena cava with almost completely unroofed coronary sinus, and critical stenosis of the proximal right coronary artery. Surgical correction of the congenital malformation associated with revascularization of the right coronary allowed a prompt recovery of clinical conditions and ventricular function.- - - - - - - - - - ranking = 0.69503268981186keywords = ventricular dysfunction, dysfunction (Clic here for more details about this article) |
7/26. Diminutive fetal left ventricle at mid-gestation associated with persistent left superior vena cava and coronary sinus dilatation.In a fetus with a small left ventricle diagnosed at mid-gestation, a persistent left superior vena cava connected to a dilated coronary sinus was detected. Although the size of the mitral annulus appeared to be normal, opening of the mitral valves was restricted in diastole. Echocardiographic follow-up showed no significant growth of the left ventricle and termination of pregnancy was carried out at 31 weeks at the parents' request. In addition to the prenatal findings, postmortem examination revealed a small mitral annulus with abnormal insertion of the mitral valve chordae tendineae. We hypothesized that abnormal venous return to a dilated coronary sinus may have led to mitral valve dysfunction and hypoplasia. On the other hand the left ventricular hypoplasia we observed may have involved a global abnormality of the left-sided cardiac structures.- - - - - - - - - - ranking = 0.0014687760241546keywords = dysfunction (Clic here for more details about this article) |
8/26. Cardiac features in the presymptomatic period in a neonate with anomalous left coronary artery arising from the pulmonary trunk.We describe a neonate presenting with a cholestatic jaundice due to alagille syndrome. On echocardiography as part of the diagnostic work-up, we noted a slight dilation of the normally functioning left ventricle at the initial examination in the third week of life. Over the next 2 weeks, serial echocardiograms showed slowly progressive dilation and dysfunction of the left ventricle, together with a persistent mild elevation of levels of cardiac troponin-I in the serum. These findings, unrelated to the underlying alagille syndrome, prompted cardiac catheterisation, which confirmed that the main stem of the left coronary artery was originating from the pulmonary trunk. Surgery was successfully performed still in the presymptomatic period. The association of alagille syndrome with anomalous left coronary artery arising from the pulmonary trunk is most unusual. We emphasise the cardiac findings prior to detection of the anomalous origin of the coronary artery.- - - - - - - - - - ranking = 0.0014687760241546keywords = dysfunction (Clic here for more details about this article) |
9/26. Anomalous left coronary artery from pulmonary artery: autogenous arterial tube for aortic implantation.Many surgical procedures for the implantation of anomalous left coronary artery from pulmonary artery have been described. A dual coronary system offers most benefit and is most advantageous for the patient. Two autogenous flaps of the pulmonary trunk and ascending aorta, without mobilizing the coronary artery, were created for use in this procedure. This technique was successfully used in an 8 month-old patient with severe myocardial dysfunction and moderate mitral regurgitation. This procedure allows 2 coronary systems to be repaired for any anatomic change of the left coronary artery without the use of prosthetic material. There were no technical complications. During the postoperative course minimal inotropic support was used. The magnetic resonance study, 11 months postoperative, showed wood flow of the left coronary artery and mild mitral regurgitation. The operative technique was simple and its execution easy. The follow-up in the intermediate and late period showed the growth of this endothelized tube.- - - - - - - - - - ranking = 0.0014687760241546keywords = dysfunction (Clic here for more details about this article) |
10/26. Cleft mitral valve in association with anomalous left coronary artery arising from pulmonary artery.An anomalous origin of the left coronary artery from the pulmonary artery is commonly associated with mitral valve insufficiency. Usually this is secondary to left ventricular dysfunction or papillary muscle ischemia. We describe the association of an anomalous left coronary artery from the pulmonary artery with structural abnormalities of the mitral valve (cleft mitral leaflet) in 2 children, both of whom were being investigated for primary mitral valve disease. Both underwent successful operations for coronary transfer and mitral valve repair.- - - - - - - - - - ranking = 1keywords = ventricular dysfunction, left ventricular dysfunction, dysfunction (Clic here for more details about this article) |
