Cath lab, short for catheterisation laboratory, is a specialised hospital facility equipped with advanced medical imaging equipment and instruments. It is a crucial part of modern medicine, where healthcare professionals perform minimally invasive procedures to diagnose and treat cardiovascular conditions. The term “cath lab" refers to both the physical space and the procedure.
In the cath lab, medical professionals, including interventional cardiologists and radiologists, utilise high-resolution X-ray equipment, imaging monitors, specialised catheters, and guide wires to access various blood vessels and organs within the body. The catheters are inserted through a small incision, usually in the groin or wrist, and guided to the targeted area using real-time imaging techniques such as fluoroscopy or angiography. In the Cath lab, healthcare professionals can perform minimally invasive procedures such as cardiac catheterisation, angiography, angioplasty, stenting, and electrophysiology studies.
How Does It Help?
Cath labs play a pivotal role in diagnosing and treating various cardiovascular conditions, such as:
They enable medical professionals to visualise the blood vessels and organs in detail, allowing for accurate diagnoses.
Catheterisation procedures performed in the lab can help identify blockages, narrowings, or abnormalities in the blood vessels, heart chambers, and valves. This information is vital in determining the appropriate course of treatment.
Cath labs are instrumental in performing interventional procedures to treat ailments such as coronary artery disease, heart valve disorders, and peripheral artery disease.
The minimally invasive nature of these interventions means that patients experience less pain, have shorter recovery times, and face fewer complications than traditional open surgeries.
Preparation
Before undergoing a cath lab procedure, thorough preparation is necessary to ensure the safety and effectiveness of the intervention. It involves:
Patient evaluation: The healthcare professionals carefully review the patient's medical history, including any allergies or previous adverse reactions to contrast agents. Additionally, they may conduct blood tests to assess kidney function and clotting abilities to prevent potential complications during the procedure.
Fasting: Doctors may advise patients to refrain from eating or drinking for a specified period before a specific procedure.
Medication review: The healthcare team will provide detailed medication management instructions, particularly regarding blood thinners and diabetic medications. Patients must follow these instructions diligently to optimise the success of the cath lab procedure.
Electrocardiogram (ECG): Patients may undergo an ECG to assess their heart rhythm and identify any underlying cardiac abnormalities before the procedure.
Vascular access site evaluation: Patients undergo an assessment of their vascular access sites, typically in the groin or wrist, before procedures involving catheter insertion. The medical staff also cleans and shaves the access area for procedures requiring access through the groin.
Treatment
After the preparation for the procedure, the medical staff will take the patient to the cath lab. The body area where the catheter will be inserted, such as the groin or wrist, is thoroughly cleansed and numbed with a local anaesthetic. The interventional cardiologist or radiologist then accesses the blood vessels using a needle and a guide wire, followed by the insertion of the catheter, which is carefully guided to the targeted area under real-time imaging guidance.
Once the catheter is in place, the doctor will perform various diagnostic or interventional procedures. Diagnostic procedures may include angiography, which involves injecting a contrast dye into the bloodstream to visualise abnormalities.
On the other hand, interventional procedures may include the deployment of stents or balloons to open narrowed or blocked blood vessels or the repair of heart valves using specialised catheter-based techniques.
Post-Treatment
After the cath lab procedure, patients are typically monitored for a few hours to ensure their stability and recovery. The medical staff will closely monitor the patient's vital signs, such as blood pressure and heart rate and promptly address any potential complications. Healthcare staff carefully observes the area where the catheter is inserted for signs of bleeding or infection.
After the procedure, doctors will advise the patients to limit physical activities and avoid heavy lifting for a specified period following the procedure. They may prescribe medications to manage pain, prevent blood clots, or control underlying conditions.
The medical staff will schedule follow-up appointments to assess the patient's progress and make necessary adjustments to their treatment plan.
Benefits
The use of cath labs in modern medicine offers numerous benefits, such as:
Catheterisation procedures performed in the lab are minimally invasive, resulting in smaller incisions, reduced pain, and faster recovery times than traditional open surgeries. It leads to shorter hospital stays and allows patients to resume their daily activities sooner.
The advanced imaging techniques used in cath labs provide exceptional visualisation of the blood vessels and organs, allowing accurate diagnoses, precise treatment planning, and real-time monitoring during interventions.
The ability to perform these procedures in a controlled environment reduces the risk of complications and improves patient outcomes.
Cath labs are helpful for various diagnostic and therapeutic procedures involving the cardiovascular system, such as:
Cardiac catheterisation
Angiography
Angioplasty
