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.

Can a polypill a day keep heart disease at bay?

A tablet designed to prevent cardiovascular disease by combining medicines to lower blood pressure and a statin to lower cholesterol added ammunition to the argument that the polypill approach works. Blood pressure and low density lipoprotein (LDL) cholesterol levels dropped as predicted in people 50 years and older who took a daily polypill, according to a study published online July 18 in PLoS One.

Multisocietal update adds ticagrelor to NSTEMI guidelines

In an update of guidelines that outline care for patients with unstable angina and non-ST-elevation myocardial infarction (NSTEMI), task force members determined that ticagrelor should be considered along with clopidogrel and prasugrel for antiplatelet therapy. Aspirin retained its position as the first-line therapy for NSTEMI patients immediately after hospitalization.

Pfizer plans to challenge retailers suit over Lipitor tactics

Pfizer said it is confident it can fend off a lawsuit filed by five retailers who claim the drug company and the generic drug manufacturer Ranbaxy Laboratories conspired to stall sales of the generic version of Lipitor.

GSK's $3 billion settlement includes Avandia count

GlaxoSmithKline (GSK) pleaded guilty to a count of failing to report safety data surrounding its diabetes drug rosiglitazone (Avandia) as part of a fraud investigation that includes a $3 billion settlement.

Bristol-Myers Squibb buys Amylin for $5.3B plus debt

Bristol-Myers Squibb will acquire Amylin in a deal totaling $7 billion after the companies boards of directors unanimously approved the acquisition.

Portrait of a TAVR patient

With this edition, we bring you the two-part installment of the FDAs Circulatory Systems Devices Panel meeting on June 13 that led to the recommendation to approve Edwards Lifesciences Sapien heart valve system for the indication to treat patients with severe, systematic aortic stenosis who are at a high risk for surgery. Now lets look at who these potential patients may be.

Circ: Dabi, warfarin have similar rates of peri-op bleeds during urgent surgery

Despite concerns of bleeding with dabigatran, a substudy published online June 14 in Circulation of the RE-LY trial found the drug had comparable rates of peri-operative bleeding and thrombotic complications when compared with warfarin. Additionally, researchers found that the subset of patients receiving dabigatran were four times more likely to have the procedure done within 48 hours of stopping anticoagulation.

Gender, missing data take center stage at FDA's PARTNER panel

The cardiovascular community has been buzzing about transcatheter aortic valve replacement (TAVR) procedures ever since the results of the PARTNER trial showed procedural benefits for inoperable aortic stenosis patients. Now, luminaries at the FDA Circulatory Systems Devices Panel are attempting to take the use of the technology a step further and tack on an additional indication for Edwards Lifesciences' Sapien heart valve system: treating patients with severe, symptomatic aortic stenosis who are high risk for surgery.

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.
