Ventricular ectopy in children without known heart disease.

Area of Science:

• Pediatric Cardiology
• Electrophysiology
• Cardiovascular Research

Background:

• Ventricular ectopy (VE) in children without underlying heart disease requires careful evaluation.
• Understanding the natural history and clinical course of pediatric VE is crucial for management.

Purpose of the Study:

• To characterize the presentation and clinical course of pediatric patients with ventricular ectopy and no known heart disease.
• To assess the long-term outcomes and progression of VE in this specific population.

Main Methods:

• Retrospective analysis of a cardiology database to identify pediatric patients with VE.
• Exclusion of patients with hemodynamically significant heart disease or systemic illnesses.
• Review of clinical presentation, echocardiographic findings, and Holter monitoring data.

Main Results:

• The study included 219 pediatric patients with VE, with a median age of 11.3 years; 83% had simple VE, and 17% had ventricular tachycardia.
• Most patients (77%) were asymptomatic at presentation, and 98% had normal echocardiograms.
• Follow-up data revealed stable or decreased VE in 54%, resolution in 40%, and worsening in 6%; only one patient developed progressive left ventricular dysfunction, and no deaths occurred.

Conclusions:

• Pediatric ventricular ectopy without known heart disease is predominantly asymptomatic and benign.
• The majority of patients exhibit stable or resolving ectopy, with a low incidence of adverse cardiac events or ventricular dysfunction.
• This suggests a favorable prognosis for children diagnosed with VE in the absence of structural heart disease.
