1/85. Successful correction of double-outlet right ventricle with a ventricular D-l-malposition of the great arteries, bilateral conus, pulmonary stenosis and subaortic ventricular septal defect.The authors present the case of a fifteen-year old girl with double outlet right ventricle with ventricular d-loop and l-malposition of the great arteries, bilateral conus, pulmonary stenosis and subaortic ventricular septal defect, who was operated on successfully. This is the fourth case of double outlet right ventricle with l-position of the aorta that has been surgically corrected. The subaortic position of the interventricular defect favours the creation of the tunnel connecting the left ventricle with the aorta without obstructing the right ventricular outflow tract. The patient was doing well 11 months postoperatively.- - - - - - - - - - ranking = 1keywords = ventricle (Clic here for more details about this article) |
2/85. Balloon pulmonary valvuloplasty in carcinoid syndrome.Half of all patients with carcinoid syndrome develop cardiac involvement. patients who have cardiac involvement have a significantly worse prognosis than those without, and death can occur directly as a result of cardiac involvement. A case of carcinoid syndrome in a 38 year old woman with lesions in the liver, who presented with right sided valvar abnormalities, a dilated right ventricle, and right ventricular pressure overload, is presented. In order to palliate the patient's symptoms and to decrease right sided pressures before major abdominal surgery, balloon pulmonary valvuloplasty was performed at the time of cardiac catheterisation. This resulted in a reduction in the pulmonary gradient and right ventricular pressure. Following the procedure, the patient's symptoms were completely relieved. She went on to laparotomy where the lesions in the liver were excised without complication.- - - - - - - - - - ranking = 0.14285714285714keywords = ventricle (Clic here for more details about this article) |
3/85. Pulmonary root translocation for biventricular repair of double-outlet left ventricle.Double-outlet left ventricle is conventionally repaired with an extracardiac conduit when pulmonary stenosis is present. We report the use of pulmonary root translocation to the right ventricle to construct the posterior wall with autologous tissue and a porcine pericardial monocusp ventricular outflow patch anteriorly for 2 patients with double-outlet left ventricle. This technique allows minimization of pulmonary insufficiency, avoids coronary artery ligation with infundibulotomy, and has a major theoretical advantage for growth potential.- - - - - - - - - - ranking = 1keywords = ventricle (Clic here for more details about this article) |
4/85. Bronchospasm induced by cardiopulmonary bypass.Severe bronchospasm during cardiopulmonary bypass (CPB) is an unusual event. A 16-year-old girl with pulmonary stenosis who underwent reconstruction of the right ventricle outflow tract experienced severe bronchospasm following CPB. Just after the initiation of the partial CPB, high inspiratory airway pressure was suddenly recognized. The lung had become too stiff for the anesthetic circuit bag to be squeezed by hand. Tracheobronchial obstruction was ruled out by investigation with a fiberoptic bronchoscope. A presumptive diagnosis of severe bronchospasm was made, and aggressive bronchodilator therapy was instituted. The attack was successfully treated with aggressive bronchodilator therapy. Although the exact causes for bronchospasm in our case are not clear, CPB factors, such as the release of complements and allergic reactions might have induced the attack under relatively light anesthetic state.- - - - - - - - - - ranking = 0.14285714285714keywords = ventricle (Clic here for more details about this article) |
5/85. Right transatrial approach to relieve pulmonary stenosis in patients with corrected transposition of the great vessels: a new operation without use of an extracardiac conduit.BACKGROUND: A new operation to relieve pulmonary obstruction is proposed for patients with corrected transposition of the great vessels and pulmonary stenosis (PS). A right transatrial approach involves excising or detaching the right-sided atrioventricular valve (AV). Next, the pulmonary outflow tract is opened wide with an incision extending from the right-sided ventricle upward across the AV valve annulus. This incision extends into the main trunk of the pulmonary artery located behind the right atrium. A patch, with or without implantation of a pulmonary valve prosthesis, widens the outflow tract, thus avoiding use of an extracardiac conduit. METHOD: We describe this operation performed in a 51-year-old man who had previously undergone correction with an extracardiac conduit that had become obstructed. The patient had severe right-sided AV valve insufficiency and complete heart block with a functioning transvenous pacemaker. We replaced the right-sided AV valve and positioned the permanent pacemaker lead outside of the prosthetic skirt. The PS was corrected as described above and a pulmonary prosthetic valve implanted. Use of an extracardiac conduit was avoided altogether. CONCLUSION: This technique may be applicable even without excising the right-sided AV valve. The clinical result for our patient is still optimal 4 years after surgery.- - - - - - - - - - ranking = 0.14285714285714keywords = ventricle (Clic here for more details about this article) |
6/85. Acquired right heart outflow tract anomaly without systemic hypertension in recipient twins in twin-twin transfusion syndrome.Significant hemodynamic changes are commonly observed in both fetuses in twin-twin transfusion syndrome. In the recipient twin there is cardiac dysfunction with hypertrophy of both ventricles and overall enlargement of the heart. We describe five cases of recipient twins in twin-twin transfusion syndrome with right ventricle hypertrophy, pulmonary stenosis and tricuspid regurgitation acquired in utero. These symptoms developed with no signs of systemic hypertension. Three of the five recipient twins survived and were developing normally at 3-30 months of age. Postnatal outcome is likely to have improved as a result of prenatal diagnosis of right ventricle outflow tract obstruction and timed delivery. These acquired anomalies of the right heart might be related to the particular hemodynamic conditions of the recipient twin. A global heart dilatation is logically expected, but this hypertrophy without dilatation is probably related to the shared plasma of fetuses with opposite hemodynamic conditions. This is what we consider as the hemodynamic-hormonal paradox. These acquired anomalies, though severe, are accessible to neonatal treatment if treated early.- - - - - - - - - - ranking = 0.42857142857143keywords = ventricle (Clic here for more details about this article) |
7/85. Single-stage anatomical repair of complete atrioventricular canal, double-outlet right ventricle, and cor triatriatum using ventricular septal defect translocation.A 17-month-old girl underwent successful single-stage anatomic repair using a technique of ventricular septal defect translocation for complete atrioventricular canal, double-outlet right ventricle, pulmonary stenosis, cor triatriatum, and left superior vena cava to an unroofed coronary sinus. We describe the repair and present clinical and angiographic data from 9 years follow-up.- - - - - - - - - - ranking = 0.71428571428571keywords = ventricle (Clic here for more details about this article) |
8/85. Exceptional survival of a patient with large ventricular septal defect, bidirectional shunt, and severe pulmonary valve stenosis.A 74-year-old man has survived in good health for an exceptionally long time despite the presence of a moderate-to-large-sized membranous ventricular septal defect (VSD). He has remained acyanotic with new york Heart association class I function. Transthoracic and transesophageal echocardiography with color flow Doppler demonstrated a membranous VSD with left-to-right and right-to-left bidirectional shunts during ventricular systole and diastole, respectively, with an right ventricular systolic pressure of 93 mm Hg, dilation of the atria and the right ventricle, and right ventricular hypertrophy. The pulmonary valve was severely stenotic with transpulmonary valve peak velocity of 6.1 m/s and a peak pressure gradient of 147 mm Hg. The pulmonary artery and inferior vena cava were mildly dilated, and the left ventricular dimension and systolic function were normal. Transesophageal echocardiography with saline solution microbubble injection demonstrated positive contrast effect in the left ventricle in diastole confirming a right-to-left shunt at the ventricular level. This man is currently the oldest survivor with a moderate-to-large-sized membranous VSD reported in the literature.- - - - - - - - - - ranking = 0.28571428571429keywords = ventricle (Clic here for more details about this article) |
9/85. A novel use of the Amplatzer muscular ventricular septal defect occluder.We report a case of a 12-month-old-infant with double outlet right ventricle and pulmonary stenosis who presented with signs of superior vena cava syndrome secondary to a dysfunctioning bidirectional Glenn shunt. The patient was successfully treated with transcatheter obstruction of an accessory pulmonary blood flow using the Amplatzer muscular ventricular septal defect occluder.- - - - - - - - - - ranking = 0.14285714285714keywords = ventricle (Clic here for more details about this article) |
10/85. 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 = 0.28571428571429keywords = ventricle (Clic here for more details about this article) |
