Right Atrial Mechanics Long‐Term after Biventricular Repair of Pulmonary Atresia or Stenosis with Intact Ventricular Septum

Abstract

Impairment of RA mechanics occurs in patients long term after repair of PAIVS and PS and is associated with RV diastolic dysfunction, longer P-wave duration, and greater P-wave dispersion.

The impact of volume overload on right heart function in end‐stage renal disease patients on hemodialysis

“…Also, the lack of reproducible and load‐independent methods raise difficulties while assessing RV function and its relation to the RA . 2D speckle tracking strain analysis, a recent development in echocardiography, might provide more consistent results and information on the functional status and physio‐mechanics of RV and RA …”

“…3,9,14 2D speckle tracking strain analysis, a recent development in echocardiography, might provide more consistent results and information on the functional status and physiomechanics of RV and RA. [15][16][17][18][19][20][21][22][23] We have therefore planned a study to evaluate the effect of volume depletion on RV and RA physiology and attempted to determine the echocardiographic parameters, which are not affected by volume changes by examining end-stage kidney patients immediately before and after hemodialysis (HD) since HD provides a rapid and considerable volume change in a short time.…”

Assessment of the Right and Left Atrial Functions at Midterm After Surgical and Device Atrial Septal Defect Closure: A 2‐Dimensional Speckle‐Tracking Echocardiographic Study

“…7,10 Two-dimensional speckle-tracking echocardiography has been used for the evaluation of the atrial functions in some congenital heart diseases such as pulmonary atresia, ASDs, coarctation of the aorta, and tetralogy of Fallot. 6,[14][15][16] There is a dearth of data in the current literature on the comparison of the atrial functions between surgical and percutaneous device ASD closure at follow-up durations of longer than 1 year. On the basis of our hypothesis that the functions of the RA and LA are at normal levels between 1 and 5 years after corrective procedures, we used 2D speckle-tracking echocardiography for the evaluation of the RA and LA functions in patients who underwent surgical or device ASD closure and a control group for longer than 1 year after the procedure.…”

Residual Restrictive Right Ventricular Physiology after One-and-a-Half Ventricular Repair Conversion in Pulmonary Atresia with Intact Ventricular Septum

“…Although long-term survival is relatively good in BVR patients, 4 restrictive RV physiology after BVR is often observed, 5 and it is associated with elevated RA pressure, RA dysfunction, 7 and increased central venous pressure, leading to end-organ damage such as liver congestion. At our institution, according to our accumulated experiences 1 and previous reports, 8 1.5VR conversion is performed for patients with PA-IVS with failed BVR who fulfill the following criteria: (1) heart failure symptoms, (2) significant PR, (3) elevated RA pressure (>10 mm Hg), and (4) liver damage assessed by ultrasound.…”
