Question:

Given the following patient information and HVAD flow waveform, how can you explain pump performance?
68 year old female, s/p HVAD™ Pump implant, post-operative day (POD) 2. Patient stable, and on the morning rounds this is what the HeartWare Monitor shows.
Medtronic HeartWare HVAD Pump Waveforms, Waveform App Normal Waveform, VAD Device Management

Answer

Normal Waveform
Discussion Points:
• Is an intervention needed?
• If yes, would it represent a patient or device intervention?

Question:

Given the following patient information and HVAD flow waveform, how can you explain pump performance?
67 year old female, s/p HVAD Pump implant, POD 0, has been in intensive care unit (ICU) for 7 hours. Patient is stable (MAP 80 mm Hg, CVP 12), on milrinone 0.375 mcg/kg/min, vasopressin 0.04 u/hr and being weaned from ventilator. She is waking up now. You go to check on her and this is what you see on the HeartWare Monitor.

Answer

Tachycardia
Discussion Points:
• Is flow impacted?
• Is an intervention needed?
• If yes, would it be a patient or device intervention?

Question

Given the following patient information and HVAD flow waveform, how can you explain pump performance?
33 year old female, s/p HVAD Pump implant for peripartum cardiomyopathy, POD 0, originally supported by an intra-aortic balloon pump (IABP), but continued to deteriorate which led to her HVAD Pump implant. She has just returned from the operating room. You are told the case went smoothly. This is what you see on the HeartWare Monitor.

Question

What could these intermittent rapid downward deflections in flow and pulsatility indicate?
medtronic heartware hvad system autologs device management mcs VAD

Answer

In this example, the HeartWare HVAD System was experiencing self-clearing suction conditions.

Question

What could this sharp increase in power indicate?
Medtronic HeartWare HVAD System Autologs Device Management VAD Thrombus

Answer

In this example, upon further evaluation the recorded increase in power consumption outside of the normal range was due to thrombus in the pump.

Question

What could this gradual decrease in HVAD Pump flow and pulsatility indicate?
Medtronic HeartWare HVAD System Autologs Device Management VAD GI Bleeding

Answer

In this example, field data later confirmed the pump’s decrease in flow and pulsatility was due to the patient having experienced a gastrointestinal bleed.
