Left ventricular wall motion abnormalities, aneurysm formation, and progression to global hypokinesis have been described in patients with myocarditis and in patients with hypertrophic cardiomyopathy. We document a case of reversible aneurysm formation, cardiogenic shock, and complete recovery in a patient with myocarditis and hypertrophic cardiomyopathy. Pathophysiologic mechanisms of myocardial injury and recovery are discussed.
