Cardiology

Cardiology is the branch of internal medicine dealing with disorders of the heart and blood vessels. The field is commonly divided in the branches of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.

Percutaneous Closure Procedure

Percutaneous closure can be described as a less-invasive surgical procedure that is used to treat patients with atrial septal defect (ASD) or patent foramen ovale (PFO). Since the utilization of percutaneous closure has evolved over the years, clinicians have already discovered multiple and less invasive methods in treatment, such as catheterization.
