double outlet right ventricle/hypoxia

Double-outlet right ventricle with mitral atresia is an uncommon anomaly with a few cases reported in the literature. We present 9 cases of this malformation that have been diagnosed by two-dimensional echocardiography (7 cases), cardiac catheterization (9 cases) and anatomical study (2 cases). We

A 3-day-old Hereford heifer calf presented for evaluation of lethargy and dyspnea, with persistent hypoxia despite supplemental oxygen therapy. A grade III/VI right apical systolic murmur was noted during cardiac auscultation. Echocardiography revealed a double-outlet right ventricle with an intact

BACKGROUND Double-outlet right ventricle (DORV) with a restrictive ventricular septum is a rare but highly morbid phenomenon that can be complicated by progressive left ventricular hypertrophy, arrhythmias, aneurysm formation, severe pulmonary hypertension, and death in the newborn. Surgical

Double outlet right ventricle (DORV) is a rare cardiac malformation especially in adulthood. We report a woman with DORV who survived to the age of 33 years. She had not been seriously limited, before she visited our hospital for cardiac evaluation at the age of 25 years. She was cyanotic, and had

We proposed a model in which myocardial hypoxia triggers the apoptosis-dependent remodeling of the avian outflow tract (OFT) in the transition of the embryo to a dual circulation. In this study, we examined hypoxia-dependent signaling in cardiomyocyte apoptosis and outflow tract remodeling. The

The embryonic cardiac outflow myocardium originates from a secondary heart-forming field to connect the developing ventricles with the aortic sac. The outflow tract (OFT) subsequently undergoes complex remodeling in the transition of the embryo to a dual circulation. In avians, elimination of OFT

CATCH 22 is a medical acronym for Cardiac defects, Abnormal facies, Thymic hypoplasia, Cleft palate, and Hypocalcemia, and a variable deletion on chromosome 22. The deletion within the chromosome region of 22q11 may occur in patients with three well-described dysmorphologic+ cardiological syndromes:

Seven patients (four previously cited and three new cases) with absent aortic valve cusps (leaflets), a rare and underrecognized complex congenital heart defect, are discussed. All patients were male, six full-term and one premature with nonimmunologic hydrops. None underwent operation; all died

Arterial hypoxemia is frequently observed after Fontan-like palliation of congenital heart defects. Whereas small systemic-to-pulmonary venous collaterals can easily be occluded by use of metal spirals, large collateral vessels may be therapeutically challenging. We report on two patients with

A patient was born with transposition of the great arteries, double-outlet right ventricle, interrupted aortic arch, and a ventricular septal defect and underwent a Damus-Kaye-Stansel procedure with a modified Blalock-Taussig shunt at 14 days old. Three months later, this patient presented with

We report the case of a newborn baby with an unguarded mitral orifice associated with asplenia syndrome, double-outlet right ventricle, dysplastic tricuspid valve, and pulmonary stenosis. This case was accompanied by severe tricuspid regurgitation and severe right ventricular hypertrophy. The

OBJECTIVE To report on the use of sildenafil for pulmonary hypertension treatment of a newborn patient after cardiac surgery. METHODS A female, full term newborn infant with diagnosis of double outlet right ventricle, pulmonary hypoplasia and subaortic ventricular septal defect, was submitted to
