Hi doctor, 6months ago i was diagnosed with mitral valve prolapse and mild mitral regurgitation, dilated left ventricle, and was given metropol. And now, i went for another 2d echo, and the result was trivial mitral regurgitation, normal left ventricle. My questions are, why the 2 findings were different? Should i do another 2d echo? Or is it possible that in a span of 6 months changes like this happens? Thank you.
