Why the study?
Atrial arrhythmia and RV diastolic dysfunction increase morbidity and mortality in repaired TOF, but whether preoperative RA volume predicts post-PVR atrial arrhythmia was unknown.
Does preoperative right atrial volume predict the development of atrial arrhythmia after pulmonary valve replacement in adult patients with repaired tetralogy of Fallot?
Does preoperative right atrial volume predict the development of atrial arrhythmia after pulmonary valve replacement in adult patients with repaired tetralogy of Fallot?
Preoperative right atrial volume index is a significant predictor of atrial arrhythmia development after pulmonary valve replacement in adults with repaired tetralogy of Fallot.
No takes yet. Share an insight, caveat, or question.
RA volume index may identify post-PVR arrhythmia risk in repaired TOF; hypothesis-generating and should not yet change practice.
