Cor triatriatum dexter(CTD)
Also known as: Cor triatriatum dextrum · divided right atrium · congenital right atrial membrane · triatrial heart
Overview
What it is
Cor triatriatum dexter is a rare heart defect present from birth where the right atrium, one of the upper chambers of the heart, is divided into two sections by an abnormal membrane. This membrane restricts the normal flow of blood returning from the body, causing fluid and pressure to back up in the veins.
How it presents
Symptoms typically appear in puppies or young dogs. Owners may notice a visibly swollen, fluid-filled abdomen, rapid tiring during play, and difficulty breathing.
Treatment
The condition is treatable, often cured through a one-time minimally invasive catheter procedure or heart surgery. This specialized intervention typically costs between 3,000 and 8,000 EUR.
