Interventional Cardiology

This cardiac subspecialty uses minimally invasive, catheter-based technologies in a cath lab to diagnose and treat coronary artery disease (CAD). The main focus in on percutaneous coronary interventions (PCI) to revascularize patients with CAD that is causing blockages resulting in ischemia or myocardial infarction. PCI mainly consists of angioplasty and implanting stents. Interventional cardiology has greatly expanded in scope over recent years to include a number of transcatheter structural heart interventions.

Circ: Size of left atrium is mortality predictor in mitral regurgitation

In mitral regurgitation caused by flail leaflets, left atrium with a diameter of 55 mm or more is associated with increased mortality under medical treatment, independent of the presence of symptoms or left ventricular dysfunction, according to a multicenter study published in the September issue of Circulation: Cardiovascular Imaging.

Stroke: Consider age when treating patients with carotid stenosis

Elderly patients treated with carotid artery stenting (CAS) faced a higher risk of stroke with increasing age compared with patients treated with carotid endarterectomy (CEA), according to a study published Oct. 6 in the online issue of Stroke. Based on the results, the authors recommend physicians take patient age into consideration when choosing a treatment for carotid stenosis.

Circ: TAVR improves quality of life for inoperable patients

Transcatheter aortic valve replacement (TAVR) provides substantial benefits over standard therapy for health-related quality of life in patients with severe aortic stenosis who were not suitable for cardiac surgery, according to research published in the Oct. 4 issue of Circulation.

Report: Endo devices replacing open surgery

Endovascular surgical techniques may outshine conventional open methods, according to a Frost & Sullivan analysis, Endovascular Surgical InterventionTechnology Market Penetration Analysis. The analysis outlined how intravascular balloons, stents and coils for varied endo procedures have become the wave of the future and have provided alternatives to CABG, carotid endarterectomy (CEA) and aneurysm clipping procedures.

Maquet parent to buy Atrium for $680M

Atrium Medical has signed a definitive agreement to be acquired by Getinge Group of Getinge, Sweden and its subsidiary Maquet Cardiovascular, for $680 million.

CMS looks into coverage of TAVI, before FDA approval

The Centers for Medicare & Medicaid Services (CMS) is reviewing the possibility of covering transcather aortic valve implantation (TAVI) after it received a formal national coverage determination request from two associations, the Society of Thoracic Surgeons (STS) and the American College of Cardiology (ACC).

PAD guidelines undergo facelift

The American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA) released updated guidelines Sept. 29 for the management and treatment for peripheral artery disease (PAD). The updates include recommended changes in practices for diagnostics, medications, interventions and patient services.

JACC: 600 mg loading dose of clopidogrel safe, effective for STEMI patients

Pre-treating STEMI patients waiting to undergo PCI with a 600 mg loading dose of clopidogrel is safe and effective compared with a 300 mg loading dose, according to a study published in the Oct. 4 issue of the Journal of the American College of Cardiology.
