Isolated noncompaction of the left ventricular myocardium complicated by thromboembolic cerebrovascular accident in a patient with essential thrombocythemia.

There are up to 3 prominent trabeculations in the normal left ventricle. Sometimes, left ventricle has excessive trabeculations and intertrabecular recesses. This appearance is called as noncompaction or hypertrabeculation. It may be together with other structural cardiac abnormalities (non-isolated) or without them (isolated). Here we present a rare case with isolated noncompaction of the left ventricular myocardium. Rarity comes from its coexistence with essential thrombocythemia. In addition, it was complicated by thromboembolic cerebrovascular accident.
