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.

NEJM: Do TAVI complications outweigh the benefits?

Months after data from the PARTNER A trial were presented at ACC.11 showed that transcatheter aortic-valve implantation (TAVI) could be an alternative to standard aortic valve replacement techniques, an editorial published online June 5 in the New England Journal of Medicine questioned whether the technique is all that promising due to its association with serious vascular and technical complications.

NEJM: Quality focus needed to improve CV surgery outcomes

While it comes as no surprise that hospital outcomes have improved over the last decade due to innovations in technologies and performance-based initiatives, outcomes across U.S. hospitals still vary. A study focused on high-risk surgeries, such as cardiovascular (CV) surgery, found that hospitals still need work and should be better focused on quality-care initiatives to further improve patient survival, according to research published June 1 in the New England Journal of Medicine.
