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.

Two antihypertensive + NSAID drugs may take toll on kidneys

Physicians who prescribe a combination of two antihypertensive drugs to their patients may want to be extra vigilant if non-steroidal anti-inflammatory drugs (NSAIDs) are added to a patient’s regimen. A study published Jan. 8 in BMJ found a triple therapy combination was associated with increased risk of acute kidney injury, with a twofold increased risk in the first 30 days of use.

Hospital, heal thyself

Many years from now we may look back at a three-page perspectives article and say: Of course, it is so obvious. But just as the campaign to reduce inhospital infections by integrating hand-washing protocols into caregivers’ practice required time to grow from idea to action, a hypothesis proposed in this week’s New England Journal of Medicine by Yale cardiologist Harlan M. Krumholz may be decades away from reducing hospital readmissions.

Hospital stressors may be catalyst for readmissions

Hospital readmissions appear to be an intractable problem, despite efforts to curb rates using interventions, penalties and other strategies. Perhaps providers and public policy leaders are focusing on the wrong target, Harlan M. Krumholz, MD, told Cardiovascular Business. His hypothesis was published Jan. 10 in the New England Journal of Medicine.

CoreValve demonstrates much higher rate of heart block post-TAVR

The most common adverse effects associated with transcatheter aortic valve replacement (TAVR) are heart block, vascular complications and renal failure. However, Prateek J. Khatri, MD, lead author of the study, told Cardiovascular Business that the CoreValve had a complication rate of 25 percent, compared with 5 percent with the Sapien valve, for the most common complication of heart block, despite a newer-generation CoreValve device used the majority of the time.

FDA approves Juxtapid for rare cholesterol disease

The FDA has approved lomitapide (Juxtapid, Aegerion Pharmaceuticals) to reduce cholesterol in patients with homozygous familial hypercholesterolemia, but the drug's labeling included a boxed warning citing the risk of liver toxicity.

Merck’s combo drug fails to reduce cardiac risks

A large clinical trial that compared extended-release niacin and laropiprant plus statin therapy with statin therapy alone was halted because it failed to meet its primary endpoint.

AstraZeneca keeps dibs on Crestor

AstraZeneca and its cholesterol drug Crestor have temporarily fended off competitors with a favorable court ruling. The pharmaceutical maker announced that a federal court declared a substance patent for rosuvastatin calcium, the active ingredient in Crestor, is valid and enforceable.

CardioSCORE’s blood test earns CE Mark

CardioSCORE, a diagnostic blood test designed to improve risk prediction of major cardiovascular events beyond traditional risk factor assessments, has received CE Mark approval in Europe.

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
