Anomalous Papillary Muscle Insertion Causing Dynamic Left Ventricular Outflow Tract Obstruction without Hypertrophic Obstructive Cardiomyopathy

<div>Gross pathology findings. (a) Specimen excised during surgery showing a hypertrophied anterolateral LV papillary muscle attached directly to the anterior mitral leaflet edge with minimal chordae present (white arrow). The anterior leaflet appears myxomatous. (b) In situ view of anomalous anterior papillary muscle (asterisk) insertion directly into anterior mitral leaflet (black arrow) which is more anteriorly displaced and extending across the LVOT.</div>
