Who can join

Age: 16 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Patients will be eligible to be included in the study if they receive either a left-sided:
• HeartMate III (Thoratec, Pleasanton, CA)
• HeartWare HVAD (HeartWare, Oakville CA)
• Levitronix CentriMag (Levitronix LLC, Waltham, MA) LVAD.

You may not qualify if…

• Patients will be excluded if::
• hemodynamic data needed to calculate PAPi or comprehensive echocardiographic images are missing
• additional procedures affecting cardiac geometry and/or hemodynamic measurements, such as tricuspid, mitral, and/or aortic valve repair/replacement, were performed at the time of LVAD implantation
• sternal closure at the end of the procedure is not possible
• RV mechanical support was introduced concurrently with LVAD implantation
• inadequate image quality required to obtain a 3D protocol
• known contraindication to TEE
• unexpected inability to advance probe into the mid-esophagus
