Abstract Aims We sought to study the prognostic impact of right atrial (RA) size and function in patients with heart failure preserved ejection fraction (HFpEF) sinus rhythm (SR) vs. fibrillation (AF). Methods results Consecutive HFpEF were enrolled indexed RA volumes emptying fractions (RA-EF) assessed by cardiac magnetic resonance imaging (CMR). For SR during CMR feature tracking wall was per...

AIMS Surgical treatment for atrial fibrillation is now feasible in selective cases. The aim of this study was to assess the electrophysiological properties of patients undergoing atrial compartment operation for chronic atrial fibrillation. METHODS AND RESULTS Electrophysiological studies were performed in 20 mitral valve patients with atrial fibrillation who had been maintained in sinus rhyt...

conclusions this case indicates that delineation of coronary artery anatomy in atypical congenital giant right atrial aneurysm is of vital importance. closure of the aneurysmal sac, instead of aneurysmal resection, is a safer and more simple approach in atypical cases. case presentation this is a report on a 3.5-month-old male infant with imperforated anus and an unusual-shaped congenital giant...

BACKGROUND Elevated right atrial (RA) pressure is an established prognostic measure in pulmonary arterial hypertension (PAH). However, little is known about perturbations in RA function in PAH. METHODS AND RESULTS Reservoir (RA longitudinal strain [RA LS]), conduit (RA early LS rate), and active (RA late LS rate) phases were assessed by 2D speckle tracking in 65 patients with PAH, 6-minute wa...

  Cor triatriatum is an acyanotic congenital heart disease. We present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. The 2D transthoracic echocardiography and the Doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dis...

BACKGROUND There is agreement that measurements of atrial volumes and ejection fraction (EF) are superior to atrial diameters for accurate determination of atrial size, follow up studies and prognosis. However, reference values for right atrial volumes and EF for cardiovascular magnetic resonance (CMR) have not been established but are crucial to identify patients with impaired right atrial fun...

critical pulmonary valve stenosis (cpvs) and atrial septal defect (asd) is an uncommon form of congenital heart disease. concurrent transcatheter pulmonary valvuplasty and closure of secundum atrial septal defect appears to be an interesting alternative to surgical correction. we present the simultaneous balloon valvuloplasty of critical pulmonary stenosis (ps) with supra systemic right ventric...
