Hypertrophic Obstructive Cardiomyopathy and Cardiogenic Shock: A Challenging Hemodynamic Situation

Hypertrophic cardiomyopathy is a genetic disease due to a mutation in cardiac muscle protein resulting in left ventricular wall and septal hypertrophy. HOCM is characterized by an excessively thick interventricular septum, which obstructs left ventricular outflow during ventricular systole. It is quite for a patient with hypertrophic cardiomyopathy to present in a state of cardiogenic shock, except in the context of major factors of decompensation leading to disruption of balance between preload and after load. When it is the case, the whole difficulty is to know the hemodynamic specifies of this pathology. Here, we report a case of 50-years-old female admitted for hypertrophic obstructive cardiomyopathy complicated by critical cardiogenic shock. This case illustrates the challenges of managing such complex hemodynamic situation.
