background: longer survival after the total repair of the tetralogy of fallot increases the importance of late complications such as right ventricular dysfunction. this is a prospective study of the right ventricular function in totally corrected tetralogy of fallot patients versus healthy children. methods: thirty-two healthy children were prospectively compared with 30 totally corrected tetra...

The site and variation of a continuous murmur and its correlation to the anatomy of aortopulmonary communications were studied in 32 patients with pulmonary atresia and large ventricular septal defect. A continuous murmur localized beneath the left clavicle was always associated with a persistent duct. When a continuous murmur beneath the left clavicle and at another site was heard in the absen...

BACKGROUND The Melody transcatheter pulmonary valve (TPV) was approved for implantation in obstructed right ventricular outflow tract conduits in 2010 after a multicenter trial demonstrating improvements in conduit obstruction, regurgitation, and right ventricular pressure. A recognized risk and contraindication to TPV implantation is the demonstration of coronary artery (CA) compression during...

BACKGROUND Complex anatomy of intra-cardiac structures requires spatial orientation of image in three dimensions for better understanding and enhanced image interpretation. We evaluated the feasibility and efficacy of the emerging 'real-time three-dimensional transthoracic echocardiography' technique for comprehensive assessment of cardiac anatomy, physiology, pathomorphology and pathophysiolog...

Double outlet right ventricle (DORV) is a heterogeneous group of congenital heart diseases that require individualized surgical approach based on precise understanding of the complex cardiovascular anatomy. Physical 3-dimensional (3D) print models not only allow fast and unequivocal perception of the complex anatomy but also eliminate misunderstanding or miscommunication among imagers and surge...

Atrial septal defect (ASD) is a common congenital abnormality that occurs in the form of ostium secundum, ostium primum, sinus venosus, and rarely, coronary sinus defects. Pathophysiologic consequences of ASDs typically begin in adulthood, and include arrhythmia, paradoxical embolism, cerebral abscess, pulmonary hypertension, and right ventricular failure. Two-dimensional (2D) transthoracic ech...

Background: The aim of this study is to evaluate the short-term results of surgical correction of Tetralogy of Fallot in adult patients. Methods: Between 1999 and 2007, surgical correction was performed in 16 adult patients (mean age: 34.6 years; range: 18 to 62). Five previous procedures had been performed in 4 patients. Thirteen patients were in NYHA functional classification III or IV (81%),...

Magnetic resonance imaging provides an accurate method for the measurement of left and right ventricular volume. The ratio of left ventricular stroke volume to right ventricular stroke volume was calculated from contiguous transverse magnetic resonance images and was used to measure the severity of regurgitation in 18 patients with aortic regurgitation and 10 with mitral regurgitation. Cardiac ...

We describe a case with pacemaker implantation for cardiac resynchronization therapy (CRT) in a patient with complex congenital heart disease, facilitated by cardiac computed tomography (CT) and coronary sinus (CS) venography. A 37-year-old male presented with congenitally corrected transposition of the great arteries and mesocardia, along with a history of two open heart surgeries (closure of ...
