Cardiac Echinococcosis: A Single-Centre Study with 25 Patients

[Giant left ventricle cardiac hydatid cyst : report of a challenging case]

Hydatidosis is a potentially fatal parasitic disease where humans are an accidental host. The cardiac location is due to the development in the heart of the larval form of Taenia Echinococcus granulosus. We present the case of a patient with a history of pulmonary hydatid cysts who presented with atypical chest pain with a huge hydatid cyst of the anterior and lateral wall of the left ventricle of 80/66 mm in diameter responsible of a thinning of the wall of the left ventricle and close relationship with the anterior descending artery and the circumflex artery. The surgery under extracorporeal circulation reconstructed the wall of the left ventricle with a double patch.

Cardiac hydatid disease; a systematic review

BACKGROUND AND OBJECTIVES

Human cystic echinococcosis (CE), is a common health problem in low- and middle-income countries. Cardiac involvement is a relatively rare manifestation of Echinococcus infection. This study aims to summarize the evidence regarding the features of cardiac CE.

METHODS

Case series of the patients with cardiac CE, were included in this study. Non-English papers, case reports, reviews, letters, , commentaries, and conference abstracts were not included. A systematic search was conducted in PubMed and EMBASE databases and the risk of bias in the included studies was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist.

RESULTS

Out of 3985 results of the searches, finally 37 studies were included in this systematic review. Based on available evidence, cardiac involvement is an uncommon but serious presentation of CE which presents with some non-specific signs and symptoms. Dyspnea, chest pain, and palpitation are the most common symptoms of the disease and normal sinus rhythm is the most common Electrocardiogram (ECG) feature. The disease is not associated with high mortality in case of timely diagnosis and appropriate management.

DISCUSSION

Consecutive and complete inclusion of participants, statistical analysis, and appropriate reporting of the demographics were the sources of bias in the included studies. The exclusion of non-English papers was a limitation during the review process.

FUNDING

The research protocol was approved and supported by the Student Research Committee, Tabriz University of Medical Sciences (grant number: 69380).

REGISTRATION

This study was registered in the International prospective register of systematic reviews (PROSPERO ID: CRD42022381204).

Cardiac Echinococcosis Associated with Other Organ Involvement: Report of Two Challenging Cases

•

Cardiac echinococcosis is a rare but potentially fatal manifestation of hydatid disease.

•

Antiparasitic agents with surgical cyst excision is the treatment of choice.

•

Heart team decision-based management is warranted in cases of other organ involvement.

Primary pericardial hydatid cyst in an asymptomatic butcher

Hydatid cyst is a serious parasitic infection in endemic areas. Cardiac hydatid cyst is not a common presentation, and primary pericardial hydatid cyst is rare. Echocardiography, CT, and MRI are important in diagnosing and locating cardiac echinococcosis. Herein, we present the case of an asymptomatic butcher with primary pericardial hydatid cyst and its successful treatment.

Brain and Cardiac Concomitant Localization of the Hydatid Cyst

Hydatid cyst is a parasitic infestation that is usually observed in the liver and lungs. The localization in the brain and the heart is exceptional. Here, we report a 11-year-old boy who was diagnosed to have two large hydatid cysts of the heart and brain. We discuss this unusual presentation of hydatid cyst and its management.

Echinococcosis in left ventricle: a case report

INTRODUCTION

Echinococcosis, also called hydatid disease, is a common parasitic infection of the liver. However, echinococcus lesions rarely involve the heart, especially in children.

PATIENT CONCERNS

An 8-year-old child from grazing areas of northwest China was referred to our hospital for the complaint of inpersistent precordial chest pain and left upper quadrant pain for 3 years. Palpation showed hepatomegaly, abdominal palpable mass while inspection abdominal distension. Routine blood tests were within the normal ranges.

DIAGNOSIS

Combining the life history in pasture area, imaging features and serology results, it was consistent with the diagnosis of cardiac echinococcosis.

INTERVENTIONS

Surgery was performed to evacuate cyst liquid and remove the internal capsule of the cyst.

OUTCOMES

There was no cystic lesion in heart on ultrasound and her physical condition improved significantly after the surgery. The patient died of hepatic hydatid cyst rupture due to refusing high-risk surgical treatment and other treatment.

LESSONS

We presented a rare case of cystic echinococcosis involving left ventricle in a child, and surgery is an alternative and effective therapy for this lesion due to the cyst rupture or leakage that can result in anaphylaxis. The typical imaging features of the cardiac echinococcosis on cardiac magnetic resonance are presented. Patient prognosis relies on proper treatment of all lesions.

Staged management of a giant cardiac hydatid cyst: a case report

BACKGROUND

We report on a 21-year-old patient with a giant symptomatic hydatid cyst of the interventricular septum, to whom a staged management approach was employed. Induction medical therapy led to a reduction in the size of the cyst, which was then completely removed via surgical excision.

CASE PRESENTATION

A 21-year-old male Caucasian, with main complaints of fatigue and palpitations, was referred to our Centre due to a cystic formation in his left ventricle. The workup consisted of transthoracic echocardiography and cardiac magnetic resonance, which revealed a huge hydatid cyst in an active stage of disease, occupying the basal and mid part of the interventricular septum. Due to the size of the lesion and lack of viable myocardium in the affected area, the patient was declared inoperable and medical therapy was initiated. Serial echocardiography revealed a significant reduction in the size of the lesion and degradation to transitional and inactive stage, after which successful surgical excision of the cyst was performed. In the course of the medical treatment, the patient experienced sustained ventricular tachycardia causing loss of consciousness, which did not reoccur after surgical excision.

CONCLUSION

Medical therapy can result in the degradation of a giant heart hydatid cyst, enabling surgical excision. Heart hydatid cyst can lead to potentially lethal arrhythmia irrespective of its size and stage, which does not reoccur after successful surgical excision.
