The 51-year-old patient with a non-compaction cardiomiopathy and multi-vessel coronary artery disease (RCD code: III-5A.1)

Left ventricular non-compaction (LVNC) or "spongy myocardium", is a rare form of a primary genetic cardiomyopathy considered to be the result of abnormal intrauterine arrest of the myocardial compaction process [1]. Left ventricular noncompaction belongs to the group of unclassified cardiomiopathies by the ESC Position Statement [2]. It is is a rare disorder characterised by a thin, compacted epicardial layer and an extensive non-compacted endocardial layer, with prominent trabeculation and deep recesses that communicate with the left ventricular cavity but not with the coronary circulation [3]. Clinical presentation of patients with LVNC is highly variable – it ranges from completely asymptomatic patients who are accidentally diagnosed (e.g. during familiar screening) to patients in need of heart transplantation [4]. Most commonly patients present with symptoms from the spectrum of the classic triad of LVNC complications: heart failure, arrhythmias and systemic thromboembolic events [5]. We describe a case of accidental discovery of isolated left ventricular non-compaction in a patient with an acute coronary syndrome.
