Paroxysmal Ventricular Tachycardia Due to Interventricular Hydatid Cyst

Abstract

A 35-year-old male patient with palpitations and mild lightheadedness was admitted to our clinic. Short-lasting paroxysmal ventricular tachycardia was diagnosed following 12-lead electrocardiography (ECG). A mass that included two-thirds of the interventricular septum and the left ventricular cavity was seen by two-dimensional echocardiography and magnetic resonance imaging (MRI). Specific hemagglutination tests for hydatid cyst were positive. The mass was excised, and the patient had a septoplasty operation to repair the remaining septal defect. He is currently being followed and reports no complaints. No evidence of arrhythmia was noted in 24-hour ambulatory ECG monitoring.

Sustained Ventricular Tachycardia as the First Manifestation of Hydatid Cyst Located in the Interventricular Septum

“…Infection of the heart occurs in 0.5-2% of all HC cases. [6][7][8] To the best of our knowledge, this is the first report of sustained VT in a patient with IVS cyst. Cardiac HCs are intramyocardial and are mostly located in the LV followed by the IVS and the right ventricle.…”

Three‐Dimensional Imaging of a Comma‐Shaped Right Ventricular Hydatid Cyst

“…Electrocardiography showed nonspecific abnormalities of T-and Q-waves, RBBB and arrhythmias such ventricular tachycardia a rarely. [1][2][3][4][5][6] Dissection of the left ventricular free wall is also reported. 6 Echinococcal eggs are ingested by humans through contaminated foods and by close contact with infected animals.…”

Progress of Untreated Massive Cardiac Echinococcosis—Echocardiographic Follow‐Up

“…When they are huge or exist in large numbers, they may lead to symptoms and signs similar to the mass of a cardiac tumor. They may cause many cardiac events such as angina pectoris, palpitations, and arrhythmias 3–5,9 …”

“…3 The distribution of cardiac echinococcosis parallels that of coronary blood flow, and most lesions occur within the left ventricle. Clinical picture depends of the location and size of the cyst [3][4][5] . Large cystic masses like a presented case may cause partial obstruction of the LV cavity and thus may result in chest pain and insidious dyspnea.…”

“…They may cause many cardiac events such as angina pectoris, palpitations, and arrhythmias. [3][4][5]9 Rupture of the cysts can embolize, causing systemic deficits when the cysts are on the left side of the heart, or pulmonary embolism when the cysts are on the right side. Moreover, some cardiac hydatid cysts may stay asymptomatic for years.…”
