Why the study?
Do clinical and phonocardiographic findings distinguish the specific anatomical site of chordal rupture or elongation in patients with severe acute mitral regurgitation?
Do clinical and phonocardiographic findings distinguish the specific anatomical site of chordal rupture or elongation in patients with severe acute mitral regurgitation?
Clinical and phonocardiographic findings cannot reliably distinguish the specific anatomical site of chordal rupture or elongation in acute severe mitral regurgitation, highlighting the need for imaging such as left ventricular cine-angiography.
No takes yet. Share an insight, caveat, or question.
Clinical exam cannot localize prolapse in acute severe MR; leaves open whether modern imaging outperforms cine-angiography.
Littler et al. (1973) studied this question.
