| Popis: | Management of patients with hypertrophic obstructive cardiomyopathy (HOCM) and severe mitral annular calcification, can be challenging. Our cases highlight the importance of addressing all elements contributing to the left ventricular outflow tract (LVOT) obstruction in cases of HOCM: hypertrophic basal interventricular septum, abnormal papillary muscles, systolic anterior motion of the anterior mitral valve leaflet. Addressing the mitral valve repair through the aortotomy, by performing a septal myectomy, papillary muscle realignment, and a resection of aberrant chordae tendineae, allows LVOT obstruction and systolic anterior motion to be successfully corrected. The success of these procedures depended on pre-operative imaging and intra-operative provocation. |
