Question 1

What is TAVI and how is it performed?

Accepted Answer

Transcatheter Aortic Valve Implantation (TAVI) is a minimally invasive procedure used to replace a narrowed aortic valve that does not open properly (aortic valve stenosis). The procedure involves inserting a catheter through the blood vessels to the heart and implanting a new valve within the old, damaged valve, improving blood flow and heart function.

Question 2

What is TMVR and when is it recommended?

Accepted Answer

Transcatheter Mitral Valve Replacement (TMVR) is a minimally invasive procedure to replace a damaged mitral valve. It is recommended for patients who are at high risk for traditional open-heart surgery. The procedure involves inserting a new valve through a catheter and placing it inside the existing mitral valve.

Question 3

What is Mitraclip and how is it used?

Accepted Answer

MitraClip is a device used in a minimally invasive procedure to treat mitral valve regurgitation, a condition where the heart's mitral valve doesn't close tightly, allowing blood to flow backward in the heart. The MitraClip is delivered to the heart through a catheter and clips the leaflets of the mitral valve together to reduce the regurgitation.

Question 4

What is Myclip and how does it help in heart treatments?

Accepted Answer

Myclip is a device used in minimally invasive procedures to treat heart valve diseases. It is similar to Mitraclip and is used to clip the leaflets of the heart valve together to improve valve function and reduce regurgitation.

Question 5

What is Left Atrial Appendage Closure and why is it performed?

Accepted Answer

Left Atrial Appendage Closure (LAAC) is a procedure to reduce the risk of stroke in patients with atrial fibrillation (AFib). The left atrial appendage is a small, ear-shaped sac in the muscle wall of the left atrium where blood clots can form. LAAC involves sealing off this appendage to prevent clots from entering the bloodstream and causing a stroke.

Question 6

How is aortic stenosis managed and treated?

Accepted Answer

Aortic stenosis, which involves the narrowing of the aortic valve, restricts blood flow from the heart. Management and treatment options include medications, surgical aortic valve replacement (SAVR), or transcatheter aortic valve implantation (TAVI), depending on the severity of the condition and the patient's overall health.

Question 7

How is mitral regurgitation treated?

Accepted Answer

Mitral regurgitation, where the mitral valve does not close properly, causes backward blood flow into the heart. Treatment options include medications, mitral valve repair or replacement surgery, and minimally invasive procedures like MitraClip or transcatheter mitral valve replacement (TMVR).

Question 8

What are degenerated bioprosthetic valves and how are they managed?

Accepted Answer

Degenerated bioprosthetic valves are previously implanted heart valves that have deteriorated over time. They can be managed with valve-in-valve procedures, where a new valve is implanted within the old one using transcatheter techniques, or through surgical replacement.

Question 9

What is the difference between surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR)?

Accepted Answer

SAVR is a traditional open-heart surgery where the damaged aortic valve is replaced with a new one. TAVR is a minimally invasive procedure where a new valve is implanted via a catheter. TAVR is often recommended for patients at high risk for surgery, while SAVR may be preferred for younger, healthier patients.

Question 10

How durable are TAVI and TMVR procedures?

Accepted Answer

TAVI and TMVR procedures have shown good durability in clinical studies, with many patients experiencing improved valve function for several years. However, long-term durability is still being studied, and regular follow-up with a cardiologist is essential to monitor valve performance.

Question 11

What is the recovery time for a TEER procedure?

Accepted Answer

Recovery from a TEER procedure is typically faster than from open-heart surgery. Most patients stay in the hospital for a few days and can resume normal activities within a few weeks, depending on their overall health and recovery progress.

Question 12

Who is eligible for TEER?

Accepted Answer

TEER is suitable for patients with severe mitral regurgitation who are high-risk candidates for open-heart surgery. This group often includes elderly individuals, those with multiple health issues, or patients with previous heart surgeries.

Question 13

What is the success rate of TEER procedures?

Accepted Answer

The success rate of TEER procedures is generally high, with many patients experiencing significant improvements in mitral regurgitation and heart failure symptoms. Clinical studies have shown favorable outcomes in terms of reduced hospitalizations and improved quality of life.

Question 14

What are the potential risks and complications of TEER?

Accepted Answer

While TEER is a minimally invasive procedure, it carries some risks and potential complications, including bleeding, infection, damage to the mitral valve, and the need for additional procedures. However, the overall risk is lower compared to traditional open-heart surgery.

Question 15

How is TEER performed?

Accepted Answer

TEER is performed using a catheter-based approach. A small clip is delivered to the mitral valve through a catheter inserted into a vein in the leg. The clip is then used to bring the edges of the mitral valve together, reducing regurgitation and improving valve function.
