Pump thrombosis in the Thoratec HeartMate II device: An update analysis of the INTERMACS Registry.
BACKGROUND Pump thrombosis in durable continuous-flow pumps is a barrier to long-term mechanical circulatory support. Earlier Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) data identified an increasing risk of pump thrombosis in recent years with the HeartMate II (HMII) left ventricular assist device. The current analysis examines pump thrombosis in the patient ...
متن کاملVADoscopy: a novel intraoperative technique to evaluate HeartMate II left ventricular assist device inflow obstruction and thrombosis.
With HeartMate II (HMII) implants increasing so has the frequency of device exchange. However, identifying inflow cannula obstruction, pump thrombosis, or outflow obstruction as the mechanism of pump dysfunction can be difficult. Echocardiography, CT angiogram, and cardiac catheterization are not definitive in determining the location of pump failure. Therefore, intraoperative examination is of...
متن کاملSurgical technique influences HeartMate II left ventricular assist device thrombosis.
BACKGROUND Thrombosis of the HeartMate II (HM2 [Thoratec Corporation, Pleasanton, CA]) is a potentially devastating complication. While attention has been focused on anticoagulation strategies to prevent this complication, the impact of surgical technique has not been assessed. METHODS Patients undergoing HM2 implantation at two institutions were reviewed. Pump thrombosis (PT) was defined as ...
متن کاملPump thrombosis redux.
Left ventricular assist devices (LVADs) are now a durable mainstay of therapy for medically refractory advanced heart failure (HF). Continuous-flow LVADs demonstrated increased longevity and enhanced quality of life in a series of landmark trials, ushering in an era where more LVADs are now implanted annually than hearts transplanted. Less than 50% of current LVAD recipients are listed for hear...
متن کاملDesign changes in continuous-flow left ventricular assist devices and life-threatening pump malfunctions.
OBJECTIVES The implantable continuous-flow left ventricular assist devices (LVADs) HeartMate II (HM II) and HeartWare HVAD (HW) underwent design modifications. The impact of these changes on life-threatening pump malfunctions was evaluated. METHODS We retrospectively analysed pump malfunctions due to thrombosis or cable damage in patients supported with primarily implanted HM II (n = 191) and...
