CARDIOLOGY TOOLS  Interventional cardiologists are experts in the cardiovascular disease who use catheters to perform cardiovascular procedures. These methods, such as angioplasty and stenting, are operated by guiding tools through the body's arteries. Tools and Devices used in the Cath Lab  Interventional cardiology is a specialization area within the broader field of cardiology. Interventional cardiologists are specifically trained doctors who have had one to two years of study and training particularly in the use of catheters – thin, flexible tubes to perform cardiovascular procedures. These systems, such as angioplasty and stenting, are completed by guiding tools through the body's blood vessels. For many patients, these minimally invasive interventional methods are an appropriate choice to open surgery. Catheters  A catheter is a slim, plastic tube that can be threaded into a blood vessel to transfer medicines inside that blood vessel. During a diagnostic a
