Intracoronary Hydatid Cyst Resulted in Coronary Artery Disease in a Young Patient

Abstract

Among all cystic echinococcosis cases, only 0.5%-2% exhibit a cardiac involvement. Only 10% of these become symptomatic. Considering the long time interval between the start of infestation and symptoms to occur, it is hard to diagnose cystic echinococcosis. When detected, even if it is asymptomatic, intramyocardial hydatid cyst requires surgical intervention due to risks of spontaneous rupture and anaphylaxis. In literature, no case of hydatid cyst located in the coronary arterial wall has been reported. Twenty-two-year-old male patient with previous history of pulmonary cystic echinococcosis was referred to us with typical symptoms of coronary artery disease. Coronary cineangiography revealed proximal left diagonal artery (LAD) occlusion. Pre-operative transthoracic echocardiography of the patient planned to undergo coronary artery bypass grafting unveiled an intracoronary calcified cystic mass. In operation, the calcified cystic mass with well-defined borders and size of 2x2 cm located within wall of proximal segment of the LAD artery was excised and double bypass with left internal thoracic artery (LITA) and great saphenous vein grafts to the LAD and first diagonal arteries, respectively, was done. Pathological analysis of the mass revealed it to be an inactive calcified hydatid cyst. Echinococcal IgG-ELISA test was positive. 12-week oral albendazole treatment (2x400 mg/day) was launched postoperatively and the patient was discharged on 7 th postoperative day.

Unusual Hydatid Cysts: Cardiac and Pelvic-Ilio femoral Hydatid Cyst Case Reports and Literature Review

“…Generally, the symptoms of the hydatid cyst only occur when the cyst expands. Patient symptoms can include allergic reactions [24] , heart failure [25] , exertional angina [26] , arrhythmias [27] , heart block [20,28] , cardiac tamponade [21] and sudden death [29] .…”

Лікування Гельмінтозів. Сучасний Погляд На Проблему

“…Кісти в печінці спричиняють біль у ділянці живота, нудоту, блювання, гепатомегалію, холестаз, біліарний цироз печінки, портальну гіпертензію, асцит, жовтяницю, утворення внутрішньоцистного або піддіафрагмального абсцесу; кісти в легенях можуть викликати біль, хронічний кашель, кровохаркання, задишку [31]. Близько 0,5-2 % пацієнтів із кістозним ехінококозом мають ураження серця, у тому числі кісти у стінці коронарної артерії, міжшлуночковій перегородці, у порожнинах серця [32]. Неспецифічні ознаки захворювання включають анорексію, втрату ваги й слабкість.…”
