Tricuspid atresia differential diagnosis

Introduction

Overview

Overview

Patients with tricuspid atresia should be differentiated from other cardiac causes of cyanosis and lung olygemia include:Tetralogy of Fallot, Truncus arteriosus, Total anomalous pulmonary venous connection, Pulmonary atresia, Tricuspid stenosis.

Differentiating tricuspid atresia from other Diseases

Patients with tricuspid atresia should be differentiated from other cardiac causes of cyanosis and lung olygemia include:

Table below compares cyanotic heart diseases:[1][2][3][4]

Disorders Etiology Clinical Presentation Laboratory Findings Electrocardiogram Findings Echocardiography Findings X-Ray Findings
Tetralogy of Fallot Multifactorial

Echocardiography may show:

  • Residual VSD or ASD
  • RV outflow tract obstruction
  • Abnormal valvular anatomy
  • The boot-shaped heart appearance
  • Normal heart size
  • Pulmonary vascular marking may be normal or decreased
Total Anomalous Pulmonary Venous Connection Multifactorial
  • Prominence of the pulmonary arteries
  • Mild enlargement of heart
  • The classic snowman sign is seen in supracardiac subtype
Tricuspid Atresia Multifactorial
  • Respiratory difficulties as nasal flaring or muscle retractions
  • Cyanosis
  • Growth retradation
  • Tall P waves indicate atrial enlargement.
  • Frontal plane QRS axis may be leftward.
 Echocardiography may show
Transposition of the Great Arteries

Multifactorial

Echocardiography may show:

  • The classic egg on string appearance
  • Pulmonary vascular marking may be normal or increased
