Doctors who specialize in cardiology (cardiologists) focus on the prevention, diagnosis, and medical management of heart disease. Some cardiologists receive additional training and become more specialized in certain areas (see below).
Doctors who specialize in interventional cardiology are cardiologists who are trained to perform procedures in the catheterization lab.
Doctors who specialize in electrophysiology focus on the treatment of arrhythmia. They are trained to perform heart rhythm procedures such as pacemaker implantation and ablation.
Heart Failure and Transplant
Doctors who specialize in heart failure and transplant are cardiologists who focus on the medical management of patients with heart failure. They are experts in caring for patients before and after heart transplant or the implantation of a left ventricular assist device.
