The HeartWare™ HVAD™ System is designed with intuitive peripherals, providing you with the information needed to better manage the device and your MCS program. Are you using it?
Waveforms
Unique to the HeartWare HVAD System, Waveforms provide real-time data for enhanced device management. Over 3,000 clinicians worldwide have downloaded the HVAD Waveforms iPad app. NOW AVAILABLE — Our improved Waveform app is available for download to your iPad today. Explore new scenarios and the all new interactive Advanced Screen which includes:
- Pressure-Volume Loops of all 4 cardiac chambers
- Aortic & Left Ventricular pressure waveforms parallel the HVAD Flow waveform for easy correlation
- Hemodynamic Outputs including AoP, PAP, PCWP, CVP, CO, EDV and EDP

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.
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.
Answer
IABP 1:2
Discussion Points:
• Is an intervention needed?
• If yes, would it be a patient or device intervention?

Question
What could these intermittent rapid downward deflections in flow and pulsatility indicate?
Answer
In this example, the HeartWare HVAD System was experiencing self-clearing suction conditions.
Question
What could this sharp increase in power indicate?
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?
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.
