Cardiothoracic Surgery

Animal Medical Center of Hattiesburg is pleased to provide a variety of cardiothoracic surgeries for your pet, including:

Patent Ductus Arteriosus Repair


Patent Ductus Arteriosus, or PDA, is a heart defect that can occur in animals when their ductus arteriosus doesn’t close at birth. The ductus arteriosus is the part of the heart that rests in between the pulmonary artery and the aorta. This is what helps to circulate blood in a pet’s heart when they are in utero.

Why would my pet need Patent Ductus Arteriosus Repair?

If the ductus arteriosus doesn’t close after birth, your pet could develop a form of congestive heart failure as they age. Patent Ductus Arteriosus Repair is a surgical procedure that will tie off the ductus arteriosus. It is important that the surgery be performed as soon as possible, as a later surgery could increase the likelihood of heart damage.



A pericardiectomy is a surgical procedure that removes the pericardium, which is the sac that sits around your pet’s heart.

Why would my pet need a pericardiectomy?

This procedure is performed if the pericardium becomes inflamed, filled with fluid, or if there is a tumor. If your pet is suffering from one of these conditions, they could potentially face congestive heart failure. Your doctor will perform radiographs and ultrasounds to determine the extent of your pet’s condition and if a pericardiectomy is necessary.

Persistent Right Aortic Arch


Persistent Right Aortic Arch, or PRAA, is a condition that occurs when your pet’s aorta doesn’t develop properly. This condition is caused by an abnormality that causes blood vessels to wrap around your pet's esophagus. This pressure can cause your pet to suffer from breathing issues and regurgitation.

How is Persistent Right Aortic Arch treated?

Your veterinarian will determine if your pet is suffering from PRAA. If so, surgical correction can be done to help shrink the abnormal blood vessels and remove pressure from your pet’s esophagus.
