Cardiac interventional therapy is the treatment of cardiac disease using minimally invasive percutaneous techniques. Cardiac catheterization has historically been considered the gold standard for diagnosis of congenital and acquired heart disease.
With the evolution of noninvasive imaging modalities (eg, echocardiography), the need for diagnostic catheterization has decreased substantially. The focus of cardiac catheterization has shifted to the development of interventional treatment strategies. Advancements in technique and equipment have allowed interventionalists to provide a less invasive approach to the definitive treatment of many types of heart disease while complementing the surgical treatment of others.
