Atrial septal defect(ASD)
Also known as: Atriumseptumdefekt · Vorhofseptumdefekt · Congenital atrial septal defect · Loch in der Herzscheidewand
Overview
What it is
An atrial septal defect is a congenital heart condition where a hole exists in the wall, called the septum, that separates the two upper chambers of the heart. This opening allows blood to flow abnormally between these chambers, which can gradually place extra strain on both the heart and the lungs.
How it presents
While dogs with small defects may show no signs, those with larger defects typically develop symptoms like rapid fatigue, coughing, or shortness of breath during exercise. These signs often become noticeable as the dog reaches young adulthood or later in life.
Treatment
Depending on the size of the hole, treatment can range from lifelong daily medication to a surgical procedure to close the defect. Total costs for specialized heart scans, veterinary cardiologist visits, and treatment typically range from 1,000 to 7,000 EUR.
