Cardiac Catheterization I: Pre-Procedure Overview

2025
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

We describe a novel surgical method for catheterizing 'intestinal loops' within the ileum of sheep. Once animals have recovered from surgery and have cleared antibiotics and analgesics, multiple treatments can be deposited directly in loops via the catheters.

The use of domestic and miniature pigs in science has increased significantly in recent years. By demonstrating how to perform intubation, transurethral bladder catheterization, femoral artery and vein catheterization, as well as transcardial perfusion, we aim to further increase the value of Göttingen minipigs in biomedical research.

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

In this video, we have demonstrated a step-by-step procedure of pulmonary artery catheterization by inserting an intravascular catheter through jugular vein and reach the pulmonary artery to measure the cardiac chamber pressure in porcine model.
FAQs
Selection should match the intended target and purpose, such as drainage, pressure measurement, medication delivery, imaging access, or another intervention. An appropriate catheter can help clinicians reach the required site while limiting unnecessary tissue injury. Choosing unsuitable equipment may make access less effective and can increase procedural difficulty or the risk of complications.
The same general approach can provide access for different clinical goals. A catheter may help clinicians measure pressure, obtain information through imaging, or deliver medication and other interventions at a target site. This combination of access and function makes catheterization useful for monitoring disease processes as well as managing them through minimally invasive treatment.
Sterile technique helps reduce the chance that microorganisms enter the body during access. Careful handling also matters because advancing a tube through a natural opening, body cavity, duct, or blood vessel can cause tissue injury if performed poorly. These precautions support safer fluid management, monitoring, diagnosis, and treatment while lowering preventable complications.
Clinicians first identify the intended target and choose a suitable catheter for the planned purpose. They then establish access through a natural opening or a small puncture, guide the catheter to the target site, and perform the required task, such as drainage, measurement, medication delivery, imaging, or intervention. Sterile practice remains important throughout the process.
Urinary catheterization commonly supports drainage and fluid management, whereas cardiac catheterization can provide access for pressure measurement, imaging, or treatment involving the heart and related blood vessels. Both use guided catheter access, but the target site and clinical objective differ. This distinction determines the procedural plan and the information or outcome clinicians seek.
Catheterization is useful when clinicians need access to a body site for drainage, monitoring, imaging, medication delivery, or treatment without relying on a larger surgical approach. Its minimally invasive nature can support fluid management and targeted care. The expected benefit must still be balanced against infection, tissue injury, and other possible complications.
