Key Clinical Message Cardiac hydatidosis is a relatively rare complication of echinococcosis. Understanding the atypical manifestations, potential associated risk factors, and epidemiology leads to optimal and timely management. Abstract Cardiac hydatidosis is a relatively rare complication of echinococcosis, with a potentially life‐threatening condition. Here, we reported a large interventricular septal hydatid cyst bulging in the left ventricle accompanied by a huge cervical lamp with recurrent hepatic cysts that underwent cardiac surgery to excise the cyst uneventfully.

Atrial fibrillation is associated with low-flow state and increased thrombogenicity in the left atrium (LA). Multiple echocardiographic presentations, including thrombosis, sludge, and smoke formation, have been demonstrated in just one biplane transesophageal echocardiographic view, along with normal structures, i.e., pectinate muscles and Coumadin ridge, which are highly educational for cardiologists.

Atrial fibrillation is one of the major predisposing factors in developing left atrial thrombosis, leading to morbidity and mortality. Echocardiography plays a paramount role in this condition's detection and subsequent treatment.
