Pulmonary Embolism in a Patient With Hypertrophic Obstructive Cardiomyopathy: Think Outside "the Box"
|
abstract
|
A patient with hypertrophic obstructive cardiomyopathy (HOCM) was
admitted with acute heart failure. Echocardiography revealed
significantly worsened left ventricular outflow tract obstruction
and pulmonary hypertension. Cardiac magnetic resonance imaging
showed biventricular dysfunction and, as an unexpected finding, a
large embolus in the right pulmonary artery. The patient gradually
improved with medical therapy including oral anticoagulation. In
HOCM patients, pulmonary embolism may trigger heart failure due to
impaired left ventricular filling with consecutive outflow tract
obstruction provocation.
