Cardiac Catheterization

Cardiac catheterization is a minimally invasive procedure that allows physicians to evaluate the heart's function and both diagnose and treat a variety of cardiovascular conditions. A thin, flexible tube called a catheter is inserted into a blood vessel, typically in the groin or wrist, and guided to the heart. This allows the doctors to measure blood pressure within the heart, evaluate blood flow, and detect blockages in the coronary arteries. If blockages are found, the procedure can also serve as a treatment allowing for angioplasty (ballooning) or stent placement to restore proper blood flow during the same procedure.

This procedure is versatile and can include:

• Diagnostic catheterization – Assesses heart function and identifies structural or vascular disease.
• Interventional catheterization – Measures pressures in the right side of the heart and lungs; often used in the evaluation of heart failure or pulmonary hypertension.
• Left heart catheterization – Focuses on the left side to detect coronary artery disease and evaluate valve or ventricular function.
• Ventriculogram – A contrast-enhanced imaging test performed during left heart catheterization to assess the pumping strength (ejection fraction) and wall motion of the left ventricle.

It is typically recommended for patients experiencing chest pain, shortness of breath, or other symptoms of heart disease. It is commonly used to detect coronary artery disease, heart attacks, heart valve disorders, congenital heart defects, and heart failure. The procedure may also be used to evaluate heart function before or after surgery or as part of a treatment plan for known cardiac conditions.

The benefits include rapid and precise diagnosis, the ability to treat blockages immediately, and minimal recovery time. It often eliminates the need for more invasive surgical procedures.

Cardiac catheterization is generally a safe procedure, but like any medical intervention, it carries some risks. Potential complications, though rare, may include bleeding or bruising at the access site, infection, irregular heart rhythms (arrhythmias), allergic reactions to contrast dye, acute kidney injury, and, in very rare cases, blood clots or heart attack. Our skilled care team takes every precaution to minimize these risks.

Preparation may involve fasting, medication adjustments, and diagnostic blood work. Our care team provides complete guidance to ensure a smooth experience.

A catheter is inserted, usually via the groin or wrist, and guided to the heart under fluoroscopy. The procedure typically takes 30–60 minutes and may include contrast dye imaging.

Patients are monitored for a few hours to ensure stable recovery. Most return home the same day, with instructions for rest and limited activity.

Recovery is typically short. Some patients may feel minor soreness at the insertion site. Our team provides aftercare support and follow-up scheduling to ensure a smooth recovery.
