LAAO stands for **left atrial appendage occlusion**. It is a way to **seal off the left atrial appendage**, a small pouch in the left upper chamber of the heart. LAAO is most commonly discussed for people with **atrial fibrillation (AF)** to help lower stroke risk. It can be done with **catheter-based devices** or **surgical techniques**, depending on the case.

Left Atrial Appendage Occlusion is a way to close off a small pouch in the heart called the left atrial appendage. It is most commonly discussed in people with atrial fibrillation, an irregular heart rhythm linked to stroke risk. It can be done with a catheter-based device or with surgical techniques, depending on the situation. Its goal is to reduce the chance that blood clots form in that pouch and travel to the brain.

Transcatheter Mitral Repair is a minimally invasive way to treat problems of the mitral valve using catheter-based devices. It is most often used to reduce mitral regurgitation, a “leaky” mitral valve that allows blood to flow backward. The procedure is typically performed in a cardiac catheterization laboratory or hybrid operating room by a specialized heart team.

MitraClip is a catheter-based device used to reduce leaking of the heart’s mitral valve. It is placed through a blood vessel, so it avoids opening the chest in many cases. It is most commonly used for mitral regurgitation in selected patients.

TAVI stands for **transcatheter aortic valve implantation**. It is a **catheter-based procedure** to replace a diseased **aortic valve** without traditional open-heart surgery. TAVI is most commonly used to treat **severe aortic stenosis**, a narrowing of the aortic valve. It is performed in specialized cardiac centers by a multidisciplinary **heart team**.

Transcatheter Aortic Valve Implantation is a minimally invasive procedure to replace a diseased aortic valve without traditional open-heart surgery. It is most commonly used to treat severe aortic stenosis, a narrowing of the valve that restricts blood flow out of the heart. A replacement valve is delivered through a catheter (a thin tube), usually from an artery in the leg. It is performed in specialized heart centers by a multidisciplinary “Heart Team.”

TAVR stands for **transcatheter aortic valve replacement**. It is a minimally invasive procedure that replaces a narrowed or failing **aortic valve** without open-heart surgery. It is most commonly used to treat **aortic stenosis**, a condition that restricts blood flow from the heart to the body. It is performed in specialized cardiac catheterization labs or hybrid operating rooms by a multidisciplinary heart team.
