Patients are sent to the cath lab primarily for advanced diagnosis and treatment of various heart and blood vessel conditions. It's a specialized hospital room equipped with imaging devices used to visualize the heart's arteries and chambers, guiding healthcare providers in identifying and addressing cardiac issues.
Key Reasons for a Cath Lab Visit
The decision to send a patient to the cath lab is typically made when symptoms suggest a potential heart problem that requires detailed investigation or immediate intervention. Here are the main purposes:
- Diagnosing and Treating Coronary Artery Blockages: A significant reason for a cath lab visit is to investigate and resolve blockages in the arteries supplying blood to the heart. Providers can precisely find and fix a blockage in your coronary artery, often using procedures like angioplasty (widening the artery) and stenting (placing a small mesh tube to keep it open).
- Diagnosing Conditions Requiring Surgery: Sometimes, the cath lab serves as a diagnostic tool to diagnose you with a condition that requires surgery. This could involve assessing the severity of valve problems, congenital heart defects, or extensive coronary artery disease, providing critical information for surgical planning.
- Obtaining Heart Tissue Samples (Biopsy): In certain cases, the cath lab is used to send a tissue sample of your heart muscle to the lab for a biopsy. This procedure is crucial for diagnosing various conditions affecting the heart muscle itself, such as myocarditis (inflammation of the heart muscle), cardiomyopathy (disease of the heart muscle), or rejection after a heart transplant.
Diagnostic vs. Interventional Procedures
The procedures performed in a cath lab can generally be categorized into two main types:
| Purpose | Description |
|---|---|
| Diagnostic | These procedures aim to uncover the cause of heart-related symptoms, such as chest pain, shortness of breath, or abnormal heart rhythms. They involve using a thin, flexible tube called a catheter to measure pressures, inject dye for X-ray imaging (angiography), or send a tissue sample of your heart muscle to the lab for a biopsy. This helps providers diagnose you with a condition that requires surgery or other treatments. |
| Interventional | These procedures are performed to treat identified issues directly. A common example is percutaneous coronary intervention (PCI), where a provider will find and fix a blockage in your coronary artery by inflating a balloon or placing a stent to restore proper blood flow. |
Understanding why patients are sent to the cath lab highlights its vital role in modern cardiology, offering both precise diagnostic capabilities and life-saving interventional treatments for a wide range of cardiovascular conditions.
