Cardionerds: A Cardiology Podcast

Brian Houston

CardioNerds (Dr. Amit Goyal), Dr. Sonu Abraham (CardioNerds Ambassador from Lahey Hospital and Medical Center, Burlington, MA) discuss left ventricular assist devices (LVAD) and the implications of renal dysfunction with Dr. Brian Houston and Dr. Nisha Bansal. This episode will focus on the intersection of left ventricular assist devices and renal dysfunction. Patients with a combination of heart failure and renal dysfunction overall have a guarded prognosis and their management poses unique challenges to the clinician. We initially discuss the basics of an LVAD and general approach to LVAD candidacy evaluation. We then discuss specific implications of acute kidney injury, presence of preexisting CKD, and end stage renal disease in patients with/being considered for an LVAD. Risk factor identification and prognostication allows for appropriate selection of the right candidates for an LVAD in the context of renal disease. Dr. Brian Houston is the Director of the Mechanical Circulatory Support program at Medical University of South Carolina. Dr. Nisha Bansal is an Associate Professor and the Arthur Stach Family Endowed Professor in the Division of Nephrology, an investigator at the Kidney Research Institute, the Director of Nephrology Clinical and Research Education, and the Director of the Kidney-Heart Service at the University of Washington. Notes were drafted by Dr. Sonu Abraham and episode audio was edited by student Dr. Chelsea Amo-Tweneboah.Check out the CardioNerds Failure Heart Success Series Page for more heart success episodes and content!CardioNerds Heart Success Series PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor RollCardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron!Pearls - Left Ventricular Assist Devices and Renal DysfunctionEnd stage renal disease (CKD on dialysis) is considered an absolute contraindication for LVAD implantation. Select young patients who are being considered for heart-kidney transplantation in the near future may be candidates for an LVAD as a bridge to heart-kidney transplantation.LVAD implantation can improve kidney function in the short term in patients with AKI primarily caused by cardio-renal syndrome.Patients with pre-existing CKD (not dialysis dependent) have a greater risk of developing AKI after LVAD implantation.  Several dialysis modalities including in-center hemodialysis, home hemodialysis, and peritoneal dialysis are available for LVAD patients. However, there are several challenges associated with each modality.An AV graft is a useful vascular access option in LVAD patients undergoing hemodialysis due to a lower risk of infection and ease of immediate use.Causes for anemia in patients with an LVAD and renal dysfunction include anemia of chronic disease, gastrointestinal bleeding, and pump thrombosis leading to hemolysis.Show notes - Left Ventricular Assist Devices and Renal DysfunctionNotes: (drafted by Dr. Sonu Abraham)What is a left ventricular assist device (LVAD) and what are its components?An LVAD supports circulation by unloading the left ventricle and providing increased cardiac output to help support organ perfusion. Use in properly selected patients is associated with improved quality of life and increased survival. The current iteration of LVADs offer continuous flow, as opposed to the older versions which employed pulsatile flow.Components of the LVAD:Inflow cannula (sucks blood from the LV)PumpOutflow cannula (dumps blood into the aorta)Percutaneous drivelineElectrical controllerHow is a patient evaluated for LVAD candidacy?The 2 main questions to be answered during the evaluation of a patient for an LVAD are:1. Are they sick enough? Do they have end stage heart failure?2. Do we expect the benefits of an LVAD to outweigh the risks?...
