Why the study?
Does left atrial contraction contribute differently to left ventricular filling in patients with aortic stenosis compared to mitral stenosis or controls?
Does left atrial contraction contribute differently to left ventricular filling in patients with aortic stenosis compared to mitral stenosis or controls?
Left atrial contraction plays a significantly more important role in left ventricular filling and performance in patients with aortic stenosis compared to those with mitral stenosis or normal controls.
No takes yet. Share an insight, caveat, or question.
May warrant preserving sinus rhythm in aortic stenosis; leaves open whether atrial optimization improves outcomes.
STOTT et al. (1970) studied this question.
