Structural Heart Disease

Structural heart diseases include any issues preventing normal cardiovascular function due to damage or alteration to the anatomical components of the heart. This is caused by aging, advanced atherosclerosis, calcification, tissue degeneration, congenital heart defects and heart failure. The most commonly treated areas are the heart valves, in particular the mitral and aortic valves. These can be replaced through open heart surgery or using cath lab-based transcatheter valves or repairs to eliminate regurgitation due to faulty valve leaflets. This includes transcatheter aortic valve replacement (TAVR). Other common procedures include left atrial appendage (LAA) occlusion and closing congenital holes in the heart, such as PFO and ASD. A growing area includes transcatheter mitral repair or replacement and transcatheter tricuspid valve repair and replacement.

Prosthesis-patient mismatch after TAVR makes minimal impact on long-term outcomes

Researchers tracked SWEDEHEART data from more than 8,000 TAVR patients treated from 2008 to 2022. Overall, they said, PPM after TAVR was rare, and its impact on outcomes was "negligible."

Get SMART: Cardiologist says new TAVR data changed his perspective on treating women with symptomatic severe AS

Sponsored by Medtronic

Physicians and researchers complete thousands of clinical trials each year, but some findings prove far more significant than others. For cardiologist Dharmesh Patel, MD, the results of the SMART trial have changed the way he’s managing and recommending treatment for women with symptomatic severe aortic stenosis.

Q&A: Interventional cardiologist breaks down SMART data and TAVR valve performance in patients with small annuli

Sponsored by Medtronic

Some of the most talked about data at ACC.24 were the results of a late-breaking clinical trial comparing different transcatheter aortic valve replacement (TAVR) valves in patients with a small aortic annulus.
