Interventional cardiology is a branch of cardiology that specializes in the diagnosis and treatment of cardiovascular diseases using minimally invasive procedures. This field involves procedures such as angioplasty, stent placement, and other techniques to open blocked arteries and improve blood flow to the heart. Interventional cardiologists use catheters and other tools to perform these procedures, often avoiding the need for surgery and allowing for quicker recovery times for patients. This field is constantly evolving with new technologies and techniques being developed to improve patient outcomes and quality of life.
