Mitral annular disjunction (MAD) is a structural abnormality defined as the separation of the ventricular myocardium between the mitral valve annulus and the left atrial wall. It is present in some patients with mitral valve prolapse (MVP) and is associated with papillary muscle fibrosis and ventricular arrhythmia. Although it is easy to diagnose, it can be overlooked in daily practice. This study presents the case of a 42-year-old patient who was admitted to the cardiology clinic with complaints of palpitation and syncope. The patient was diagnosed with bileaflet MVP, MAD, and severe mitral regurgitation using transthoracic echocardiography and cardiac magnetic resonance imaging, in which ventricular tachycardia disappeared following subsequent surgical repair.Mitral anular disjunction (MAD), mitral kapak anulusu ile sol atriyal duvar arasında ventrikülün miyokarddan ayrılması olarak tanımlanan yapısal bir anormalliktir. MAD, mitral valv prolapsusu (MVP) olan hastaların bir kısmında bulunmakta olup MVP’den bağımsız olarak papiller kas fibrozu ve ventriküler aritmi ile ilişkilidir. Tanısı kolay olmasına rağmen günlük pratikte büyük oranda akla gelmemesi nedeniyle gözden kaçabilmektedir. Bu olguda, çarpıntı ve senkop şikayeti ile kardiyoloji kliniğine başvuran, transtorasik ekokardiyografi ve kardiyak manyetik rezonans görüntüleme ile biliflet MVP, MAD ve ileri mitral yetersizliği tespit edilen ve cerrahi tamir sonrasında ventriküler taşikardinin kaybolduğu 42 yaşındaki olguyu sunmayı amaçladık.
