Thoratec issues safety advisory after 4 deaths

Four patients who received the HeartMate II left ventricular assist system pocket system controller have died and five more patients have either lost consciousness or experienced other problems, Thoratec announced in a safety advisory.

Warfarin may benefit CKD patients without adding bleeding risk

Compared with non-users, Swedish patients with advanced chronic kidney disease (CKD) and atrial fibrillation who received warfarin therapy were less likely to die, have an MI or stroke at no added risk of bleeding in an observational study published March 5 in JAMA.

Valvular heart disease guidelines add TAVR, updates

Recently released practice guidelines for treating patients with valvular heart disease forged new ground on several fronts. For the first time, they included recommendations for transcatheter aortic valve replacement (TAVR) as well as a new classification system.

Transradial PCI may lower risk of acute kidney injury

To prevent acute kidney injury (AKI) in patients undergoing PCI, physicians may want to select a transradial approach rather than a transfemoral approach. A study published online Feb. 25 in Circulation: Cardiovascular Interventions found an association between radial PCI and a lower risk of AKI compared with the femoral approach.

Aortic stenosis: Lifelong learning in the 21st century

Transcatheter aortic valve replacement (TAVR) for eligible patients with severe aortic stenosis holds great promise but much still needs to be learned. The American College of Cardiology (ACC) is piloting an initiative that is designed to help valve centers in the U.S. improve quality and achieve good outcomes.

BP differences between arms may increase cardiovascular risk

A difference in systolic blood pressure between arms may indicate an increased risk for cardiovascular events in the future, even if the difference is modest, researchers found in a study published in the March issue of the American Journal of Medicine.

FDA approves catheter for AF ablation

The FDA approved a therapeutic catheter that can be used to measure contact force during cardiac ablation.

AHA panel: Depression should be risk factor

Depression has been linked to poor outcomes in patients with certain cardiac conditions, and an American Heart Association (AHA) panel argued in a scientific statement published online Feb. 24 in Circulation that it should be considered a risk factor for poor prognosis among patients with acute coronary syndrome.
