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.

Robotic mitral valve repair linked to benefits for elderly patients

Robotic and traditional mitral valve repair surgeries are mostly associated with similar outcomes when treating elderly patients. In some ways, however, robotic procedures may be preferred. 

Alexander Kolomaya, MD, a cardiology resident at the University of Utah, presented a study on U.S. national trends in left atrial appendage occlusion (LAAO) volume and open payments from vendors to operators at the American Heart Association 2024 meeting.

Vendor payments not responsible for rising popularity of LAAO procedures

Consulting fees and other vendor payments do not appear to be directly influencing U.S. physicians to implant more Watchman devices. Researcher Alexander Kolomaya, MD, discussed his team's findings on this topic.

Michael J. Reardon, MD, the Allison Family Distinguished Chair in Cardiovascular Research and a professor of medicine at the DeBakey Heart and Vascular Center, Houston Methodist Hospital, explains the late-breaking five-year results of the Evolut Low-Risk Trial presented at the American College of Cardiology (ACC) 2025 meeting. The data show positive results for the Evolut transcatheter aortic valve replacement (TAVR) system vs. surgical aortic valve replacement (SAVR).

Self-expanding TAVR valves deliver outcomes and durability comparable to surgery after 5 years

Michael Reardon, MD, detailed five-year data out of ACC.25 that found Medtronic's Evolut TAVR platform performs as well as SAVR—and even better in some ways.

Underweight TAVR patients face higher mortality risk—obesity makes no significant impact

Reviewing data from more than 6,000 patients, researchers found little evidence of the "obesity paradox" observed elsewhere. Underweight TAVR patients, however, may face some significant long-term risks.

Society of Cardiovascular Angiography and Interventions (SCAI) President James B. Hermiller, Jr., MD, director of the transcatheter structural heart program at Ascension St. Vincent Heart Center in Indianapolis, explains SCAI's push for wider adoption of new, innovative cath lab radiation protection technology to reduce radiation exposure and the need for lead aprons that cause orthopedic injury.

Myval TAVR valve non-inferior to Sapien 3 after 1 year—pacemaker implants the biggest difference

India-based Meril Life Sciences has been manufacturing its Myval transcatheter heart valves for years, but the technology has not yet gained FDA approval. This latest head-to-head comparison included data from more than 1,000 TAVR patients.

Oversizing reduces PVL when implanting Medtronic’s newer self-expanding TAVR valves

Paravalvular leak has been shown to impact patient outcomes after TAVR. Higher degrees of valve oversizing, however, can reduce the risk of post-treatment PVL without increasing the odds of adverse outcomes.
