Hypereosinophilic heart disease

Area of Science:

• Cardiology
• Hematology
• Internal Medicine

Background:

• Idiopathic hypereosinophilic syndrome (HES) is a rare disorder characterized by persistent eosinophilia.
• Cardiac involvement in HES can lead to severe heart failure and is associated with poor prognosis.

Observation:

• A 45-year-old patient presented with progressive congestive cardiac failure attributed to cardiac HES.
• Cardiac investigation revealed bilateral ventricular infiltration with endomyocardial fibrosis, causing hemodynamic compromise and atrioventricular valvular incompetence.

Findings:

• The patient underwent extensive cardiac surgery, including bilateral ventricular endomyomectomy and replacement of the mitral and tricuspid valves.
• Post-operative recovery showed significant hemodynamic improvement and symptomatic relief for six months.

Implications:

• This case highlights the potential for significant cardiac dysfunction in HES.
• Surgical management, while invasive, can provide temporary but substantial benefit in select cases of cardiac HES.
• Further research into medical and surgical strategies for cardiac HES is warranted.
