PDA / Heart Murmur Surgery for a Biewer Terrier Puppy
A heart murmur is an abnormal heart sound that is heard when listening to the heart with a stethoscope. It is caused by abnormal turbulent blood flow. Abnormal turbulent blood flow can occur when blood passes across abnormal heart valves or across abnormal structures within the heart. An echocardiogram (ultrasound of the heart) is a non-invasive test that is performed to determine the cause of the murmur.
