Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Cyanosis
Bluish discoloration of the skin, lips, and fingernails due to insufficient oxygen in the blood.
Seek immediate medical attention if cyanosis appears suddenly or worsens, as this indicates critical oxygen deprivation.
Hypotension
Abnormally low blood pressure indicating poor cardiac output and circulatory compromise.
This is a medical emergency; seek immediate emergency care if infant shows signs of shock or collapse.
Dyspnea
(respiratory)Shortness of breath or difficulty breathing, especially during feeding or physical activity.
Frequency: 75-90% of patients
Heart Murmur
(cardiovascular)Abnormal sound heard during heartbeat due to turbulent blood flow through abnormal heart structures.
Frequency: 80-95% of patients
Failure to Thrive
(constitutional)Inadequate weight gain and growth due to increased metabolic demands and poor feeding tolerance.
Frequency: 60-75% of patients
Tachypnea
(respiratory)Abnormally rapid breathing rate as the body compensates for reduced oxygen delivery.
Frequency: 65-80% of patients
Poor Feeding
(gastrointestinal)Difficulty with feeding, fatigue during feeding, or reduced intake due to respiratory distress and fatigue.
Frequency: 55-70% of patients
Fatigue
(constitutional)Extreme tiredness and low energy levels, especially during feeding or activity.
Frequency: 50-65% of patients
Digital Clubbing
(dermatologic)Rounding and enlargement of fingertips and toes, with abnormal nail bed curvature.
Frequency: 10-20% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease management and monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Targeted Fetal Echocardiography
Specialized cardiac ultrasound focused on evaluating outflow tract abnormalities, valve function, and great vessel architecture with precise measurements.
Fetal Balloon Valvuloplasty
In utero catheter-based procedure to relieve critical obstruction in the outflow tract, potentially allowing improved cardiac development.
Additional treatment options
Maternal Prostaglandin Inhibitors
Careful use of medications to maintain ductal patency when outflow obstruction may compromise fetal circulation.
medicationEXIT Procedure for Delivery
Ex utero intrapartum treatment procedure maintaining placental circulation while securing airway or initiating cardiac stabilization.
surgicalCorrective Cardiac Surgery
Definitive surgical repair of outflow tract abnormalities performed after birth when the infant is medically stable.
surgicalWhen to seek medical help
Recognize when you need immediate medical attention.
See a doctor within 24 hours
Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.
Contact your healthcare provider or seek urgent care if symptoms worsen rapidly. Go to the emergency department for life-threatening symptoms.
