Bi-atrial function and its relation with biventricular function and clinical parameters in patients operated for tetralogy of Fallot
نویسندگان
چکیده
Background Biventricular size and function have been studied extensively in patients after tetralogy of Fallot (TOF) repair, but little is known about atrial size and function. The atria play a crucial role in ventricular filling during diastole, and abnormalities in atrial size and function may reflect ventricular diastolic dysfunction. Diastolic dysfunction may precede systolic dysfunction and may therefore play an important role in the early detection of ventricular dysfunction.

Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined dia...

Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

BACKGROUND Parameters of myocardial deformation have been suggested to be superior to conventional measures of ventricular function in patients with tetralogy of Fallot (ToF), but have required non-routine, tagged cardiovascular magnetic resonance (CMR) techniques. We assessed biventricular myocardial function using CMR cine-based feature tracking (FT) and compared it to speckle tracking echoca...

Introduction: Since 1954, after the first surgical repair of tetralogy of Fallot (TOF), several innovations have occurred in cardiac surgery, especially in children. One stage complete repair of TOF is currently possible even in infancy; however, complications such as hypoxemia, arrhythmia, cardiac dysfunction, sudden death, and valvular disorders may happen. In this study, we evaluated the res...

Background Left atrium enlargement is directly proportional to the severity of underlying clinical (or subclinical) cardiovascular disease. Right atrium (RA) measurements are not routinely performed despite their prognostic value has been demonstrated in chronic heart failure, atrial and pulmonary arterial hypertension. The aim of the study was to evaluate RA dimensions and volumes by cardiac M...
