@ecocardio_cl Was there mid ventricular obstruction/mid Cavity gradient? Echo appears to be consistent with HCM variant with abnormal papillary muscle anatomy if you noticed the elevated gradient. Just a thought.
@MusaSharkawiMD@esbrilakis Nice case, great demonstration of algorithmic approach for complex calcified lesion. Question, did you use the same burr for 10 minutes or had to change the burr?
