Cardiac catheterization is considered a minimally invasive procedure compared to traditional open-heart surgery, providing valuable diagnostic information with a relatively low risk of complications. It is an essential tool in the field of interventional cardiology, enabling precise and targeted treatments for coronary artery disease. In cases where significant blockages are identified, angioplasty may be performed to widen narrowed arteries, and stents may be inserted to help maintain the vessel's patency. The procedure is typically conducted in a specialized cardiac catheterization laboratory (cath lab) by a skilled team of interventional cardiologists and supporting healthcare professionals. Cardiac catheterization plays a pivotal role in guiding treatment decisions, improving patient outcomes, and contributing to advancements in the understanding and management of cardiovascular diseases.
