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.

Predictors of 1-year mortality after TAVR are significantly different among men and women

Atrial fibrillation and peripheral artery disease, for example, are both predictors of mortality among women, but not men.

A team of cardiologists and cardiac surgeons in Hong Kong has performed the first successful undermining iatrogenic coronary obstruction with radiofrequency needle procedure—or UNICORN for short—on a high-risk valve-in-valve transcatheter aortic valve replacement (TAVR) patient. The group wrote about their experience in Circulation: Cardiovascular Interventions, a journal launched and distributed by the American Heart Association.

Cardiologists make history, perform first UNICORN procedure during valve-in-valve TAVR

BASILICA was considered for the 67-year-old female patient, but UNICORN was seen as an overall better option. The full case study was published in Circulation: Cardiovascular Interventions.

Albuminuria linked to worse TAVR outcomes, including a higher risk of death

“Because patients with aortic stenosis are old and commonly have chronic kidney disease, it is essential to evaluate the renal function before TAVR," the study's authors wrote. “Albuminuria indicates glomerular injury and is an important factor in the assessment of renal function or diagnosis of chronic kidney disease."

In-hospital complications are more common among women who undergo LAAO than men. However, according to a new study in JACC: Cardiovascular Interventions, men and women have similar long-term outcomes.

Transcarotid TAVR a safe alternative when femoral access is not an option

The conventional transfemoral approach is not always possible during TAVR procedures, leaving care teams with an important decision to make.

Transcatheter aortic valve replacement (TAVR) patients who suffer from cognitive impairment face a higher risk of one-year mortality and developing postoperative delirium (POD), according to a new study published in the American Journal of Cardiology.

An updated look at how cognitive impairment affects TAVR outcomes

The connection between cognitive impairment and postoperative delirium among TAVR patients stood out as a definite concern to the study's authors.

What does radiology have to do with climate change?

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
