HEARTMATE II PUMP STOPS: THE SHORT TO SHORT PHENOMENON

Principles of HeartMate II Implantation to Avoid Pump Malposition and Migration

Proper left ventricular assist device (LVAD) insertion will help maximize LVAD flow and may reduce adverse events such as right heart failure and pump thrombosis. Although no standardized insertion technique has been universally accepted, the goals are: unobstructed inflow cannula, unobstructed outflow graft with avoidance of right ventricular compression, and prevention of pump migration. To a...

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 ...

A model with otp(pcf(a)) = ω1 + 1 is constructed, for countable set a of regular cardinals. 1 Preliminary Settings Let 〈κα | α < ω1〉 be an an increasing continuous sequence of singular cardinals of cofinality ω so that for each α < ω1, if α = 0 or α is a successor ordinal, then κα is a limit of an increasing sequence 〈κα,n | n < ω〉 of cardinals such that (1) κα,n is strong up to a 2-Mahlo cardi...

A Short Introduction to Clinical Photography for the Plastic Surgeon

Heartmate II outflow graft ligation and driveline excision without pump removal for left ventricular recovery.

We report interruption of left ventricular assist device (VAD) support by way of outflow graft ligation and driveline excision while leaving the pump in situ. In this case, the indication for mechanical assist device separation was myocardial recovery, which occurred following 9 months of support. This case report demonstrates the feasibility of separating a patient from a VAD without the need ...
