Diagnosis of recurrent PDA typically involves several methods:
- Echocardiogram: This is the most definitive diagnostic tool, providing detailed images of the heart and blood flow. - Chest X-Ray: May show an enlarged heart or signs of pulmonary congestion. - Cardiac Auscultation: Listening for a distinct heart murmur can suggest PDA. - Oxygen Saturation Monitoring: Low oxygen levels can indicate a mixing of blood due to PDA.
