Patent Ductus Arteriosus (PDA) in Dogs and Cats
A patent ductus arteriosus (PDA), also known as Botallo's duct, is a common congenital heart defect in dogs and is less common in cats. This condition occurs when the blood vessel connecting the pulmonary artery to the aorta in the fetus (ductus arteriosus) fails to close properly after birth

A pericardial effusion is an accumulation of an abnormal amount of fluid in the pericardial sac, the thin fibrous membrane that surrounds the heart. Normally, the pericardial sac contains a small amount of fluid, which provides lubrication and allows the heart to move freely.
