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.

Cardiac CT before TAVR detects CAD with high accuracy, suggesting a reduced need for invasive imaging

New research from a team of specialists at Cleveland Clinic included data from more than 2,000 TAVR patients.

How monitoring MR can help cardiologists anticipate TAVR outcomes in patients with low-flow, low-gradient AS

Researchers uncovered new details about how mitral regurgitation can impact one-year TAVR outcomes, sharing their findings in the Journal of the American Heart Association.

Performing valve-in-valve transcatheter mitral valve replacement (ViV TMVR) with conscious sedation (CS) or monitored anesthesia care (MAC) instead of general anesthesia (GA) is safe and effective, according to new research published in JACC: Cardiovascular Interventions.

Cardiologists detail long-term outcomes of valve-in-valve TMVR

New research published in the Canadian Journal of Cardiology represents one the most detailed pictures to date of the long-term impact of ViV TMVR.

TAVR safe and effective for severe AS patients with a very low gradient

Yes, all-cause cause mortality is higher among TAVR patients with a very low baseline gradient, but the difference is almost entirely due to those patients presenting with more comorbidities.
