Asymptomatic Cardiac Heave in a 5-Year-Old

An asymptomatic right-sided cardiac heave (parasternal heave) in a 5-year-old child requires transthoracic echocardiography performed at a pediatric cardiology facility to rule out structural heart disease, assess for right ventricular hypertrophy or dysfunction, and evaluate for pulmonary hypertension. 1

Clinical Significance

A right-sided cardiac heave (parasternal lift) indicates right ventricular hypertrophy or volume overload. Even in asymptomatic children, this physical finding warrants investigation because:

  • It may represent undiagnosed congenital heart disease (atrial septal defect, ventricular septal defect, pulmonary stenosis)
  • It could indicate pulmonary hypertension, which can be progressive and life-threatening if untreated
  • Early detection allows intervention before irreversible pulmonary vascular changes occur

Diagnostic Approach

Initial Evaluation

Perform a focused physical examination looking for:

  • Cyanosis or differential cyanosis
  • Clubbing of digits
  • Quality and splitting of the second heart sound (fixed splitting suggests ASD)
  • Presence and timing of murmurs (systolic ejection murmur at left upper sternal border suggests pulmonary stenosis or ASD)
  • Signs of right heart failure (hepatomegaly, jugular venous distension - though rare in asymptomatic children)

Essential Testing

1. 12-Lead ECG 1

  • Look for right ventricular hypertrophy (tall R waves in V1, right axis deviation)
  • Assess for right atrial enlargement (peaked P waves in lead II)
  • Rule out arrhythmias or pre-excitation

2. Transthoracic Echocardiography (Mandatory) 1

The echocardiogram must include:

  • Exclusion of congenital heart disease with specific attention to:

    • Atrial septal defects
    • Ventricular septal defects
    • Patent ductus arteriosus
    • Pulmonary valve stenosis
    • Anomalous pulmonary venous return

  • Right ventricular assessment:

    • RV size and function (qualitative and quantitative)
    • RV systolic pressure estimation via tricuspid regurgitation jet velocity
    • Presence of RV hypertrophy

  • Pulmonary hypertension screening:

    • Tricuspid regurgitant jet velocity (TRJV)
    • Septal position and motion
    • Pulmonary artery acceleration time

  • Left ventricular function to exclude left-sided causes of elevated right heart pressures

Risk Stratification Based on Findings

If Structural Heart Disease is Found:

For significant shunt lesions (ASD, VSD, PDA):

  • If pulmonary vascular resistance index (PVRI) <6 Wood units·m² or PVR/SVR <0.3: repair should be considered 2
  • If PVRI ≥6 Wood units·m²: cardiac catheterization with acute vasodilator testing is needed before determining operability 2
  • Early repair (by 1-2 years of age) is generally recommended to prevent development of pulmonary vascular disease 2

For pulmonary stenosis:

  • Trivial (gradient <25 mmHg): no intervention needed, follow every 5 years 3
  • Mild (gradient <50 mmHg): periodic follow-up without intervention 3
  • Moderate to severe: referral for balloon valvuloplasty or surgical intervention 3

If Pulmonary Hypertension is Suspected:

Echocardiographic criteria suggesting PH:

  • TRJV >2.5 m/s (corresponds to estimated RV systolic pressure >36 mmHg)
  • Flattening or leftward bowing of interventricular septum
  • Dilated right ventricle with reduced function

Next steps if PH is identified:

  • Cardiac catheterization is required before initiating PAH-specific therapy 2
  • Evaluate for underlying causes:
    • Chronic lung disease
    • Sleep-disordered breathing (polysomnography)
    • Chronic hemolytic anemia (sickle cell disease)
    • Liver disease (porto-pulmonary hypertension)
    • Thromboembolic disease

Common Pitfalls to Avoid

  1. Do not dismiss an asymptomatic heave as benign - Many serious cardiac conditions present without symptoms in children, and physical examination findings may be the only clue 1

  2. Do not rely on chest X-ray alone - While it may show cardiomegaly or increased pulmonary vascular markings, echocardiography is mandatory for definitive diagnosis 1

  3. Do not perform echocardiography at a non-pediatric facility - Pediatric congenital heart disease requires specialized expertise for accurate diagnosis 1

  4. Do not delay evaluation - 87% of new-onset heart failure cases in children are only diagnosed when severely decompensated 1

  5. Recognize that rare cardiac masses can present with heaves - Though uncommon, right-sided cardiac tumors (myxomas, papillary fibroelastomas) can occur in children and may be asymptomatic 4, 5, 6

Follow-Up

  • If echocardiography is completely normal, the heave may represent a normal variant in a thin-chested child or increased cardiac awareness
  • If abnormalities are found, follow-up intervals depend on the specific diagnosis but typically range from 3-6 months for stable conditions 1
  • Any change in clinical status (development of symptoms, decreased exercise tolerance, syncope) warrants immediate re-evaluation 1
