Patent ductus arteriosus and pulmonary hypertension(PDA)
Also known as: Patent Ductus Arteriosus with Pulmonary Hypertension · Reversed Patent Ductus Arteriosus · rPDA · PDA with Eisenmenger's syndrome · Persistierender Ductus arteriosus Botalli mit Lungenhochdruck
Overview
What it is
This is a severe congenital heart defect where a blood vessel connecting the aorta and the pulmonary artery fails to close after birth. This failure causes high blood pressure in the lungs, known as pulmonary hypertension, which can eventually force oxygen-poor blood to flow backward into the body's main circulation. An echocardiogram, which is a specialized heart ultrasound, is the gold standard method used to diagnose this condition and evaluate the direction of blood flow.
How it presents
Affected dogs typically show signs during puppyhood or adolescence. Owners may notice severe exercise intolerance, shortness of breath, coughing, fainting spells, or a bluish tint to the gums.
Treatment
If pulmonary hypertension has already developed, corrective surgery is usually no longer possible, requiring lifelong medical therapy instead. Lifetime management and diagnostic monitoring typically cost between 3,000 and 12,000 EUR.
