ABSTRACT
A 50-year-old black man presented at the emergency department with midsternal, nonradiating chest pressure and chronic dyspnea on exertion. Four years before the current admission, he had been diagnosed with nonischemic cardiomyopathy at another facility. After our complete evaluation, we suspected that his symptoms arose from left-to-left shunting in association with pulmonary sequestration, a congenital malformation. Our preliminary diagnosis of secondary dilated cardiomyopathy was confirmed by normalization of the patient's ventricular size and function after lobectomy. To our knowledge, this patient is the oldest on record to present with cardiomyopathy consequent to pulmonary sequestration. His case is highly unusual because of his age and the rapid resolution of his symptoms after lobectomy. We believe that pulmonary sequestration should be included in the differential diagnosis of dilated cardiomyopathy.
