[Association of non-compacted myocardium and patent ductus arteriosus in a young asymptomatic male patient: findings in screening for contact sport eligibility].
Spongy or noncompacted myocardium is a rare congenital cardiomyopathy characterized by parietal myocardial structural alterations secondary to intrauterine arrest of myocardial fiber compaction. It can be associated with other congenital cardiovascular malformations or manifest as an isolated disease. It is characterized by a wide variety of clinical presentations that range from complete absence of symptoms to thromboembolic manifestations, ventricular arrhythmias and congestive heart failure; the short- and mid-term prognosis is quite severe. We here describe a casual finding of an advanced form of noncompacted myocardium associated with patent ductus arteriosus in a young asymptomatic athlete during a routine visit for agonistic sports eligibility. Although the patient had a normal functional capacity, transthoracic echocardiography showed left ventricular dilation with a moderately depressed contractile function and the presence of numerous prominent trabeculae and deep intertrabecular recesses which communicated with the left ventricular cavity. These findings which were confirmed by further echocardiographic examinations, and the absence of other cardiovascular disorders associated with this disease, led us to the diagnosis of noncompacted myocardium. The patient was not allowed to perform sports activities and underwent percutaneous closure of the patient ductus arteriosus. He was asymptomatic and because in the recent literature there are no data regarding pharmacological therapy in these patients, the subject was submitted to routine clinical follow-up evaluation with no medical therapy.
