Cath lab (short for catheterization laboratory) is a specialized medical facility equipped with diagnostic imaging technology and tools used to perform minimally invasive procedures on the heart and blood vessels.
Minimally invasive procedures are medical procedures that are performed using small incisions or through natural openings in the body, such as the mouth or nose, rather than larger incisions required for traditional open surgery. These procedures are typically less traumatic to the body and require less recovery time than traditional open surgery.
These procedures are made possible by advances in medical technology, such as specialized instruments and imaging technology, which allow doctors to perform complex procedures using smaller incisions. Examples of minimally invasive procedures include laparoscopic surgery, in which a small camera and instruments are inserted through small incisions to perform abdominal surgery, and endoscopic procedures, in which a thin, flexible tube with a camera is used to examine the digestive tract.
In addition to surgical procedures, minimally invasive techniques can also be used for diagnostic purposes, such as in cardiac catheterization, where a catheter is inserted into an artery to diagnose heart conditions.
What is a cath lab? An overview
Cath labs are typically located within hospitals or medical centers, and are staffed by a team of healthcare professionals, including cardiologists, radiologic technologists, and nurses, who work together to diagnose and treat various cardiac and vascular conditions.
During a typical cath lab procedure, a small incision is made in a patient’s skin, and a catheter (a thin, flexible tube) is threaded through an artery or vein and guided to the heart or other target location.
Once the catheter is in place, diagnostic tests, such as angiograms, can be performed to evaluate blood flow and identify any blockages or other abnormalities.
In addition to diagnostic procedures, cath labs are also used to perform minimally invasive treatments, such as angioplasty, stent placement, and cardiac ablation, which can help improve blood flow and treat various heart and vascular conditions.
Catheterization laboratory team members/staff
The team members who work in the cath lab are highly trained professionals who work together to ensure the safety and well-being of the patient during the procedures.
