Cardiomems™ In Lvad Patients: A Case Series, Maya Guglin, Bennet George, Sarah Branam, Amanda Hart
The VAD Journal
Patients with a left ventricular assist device (LVAD) commonly encounter issues with volume status post-implant. Volume overload can result from incomplete compensation of left ventricular failure or from right ventricular failure. The CardioMEMS™ intracardiac hemodynamic monitoring device is an area of growing interest regarding the management of chronic congestive heart failure, however, its utility has not been serially investigated in patients with an LVAD. We present a case series of patients with ventricular assist devices care for at our institution in which the CardioMEMS™ device aided in the management of volume status and pump performance.
Ligation Of The Outflow Graft Of The Left Ventricular Assist Device For Management Of Hemolysis Due To Pump Thrombosis, Jean Touchan, Alexis Shafii, Maya Guglin
Ligation Of The Outflow Graft Of The Left Ventricular Assist Device For Management Of Hemolysis Due To Pump Thrombosis, Jean Touchan, Alexis Shafii, Maya Guglin
The VAD Journal
Pump thrombosis is a serious complication of continuous-flow left ventricular assist devices (LVAD). Treatment options include medical thrombolysis, surgical pump exchange or urgent heart transplantation. We are reporting a case of pump thrombosis with active hemolysis and acute renal failure managed surgically by isolating the LVAD while awaiting renal recovery and donor heart availability.
Caregiver Burden Is Low Nine To Twelve Months After Ventricular Assist Device Implantation, Roxana Ghashghaei, Hao Tran, Jorge Silva, Barry H. Greenberg, Denise Barnard, Eric Adler
Caregiver Burden Is Low Nine To Twelve Months After Ventricular Assist Device Implantation, Roxana Ghashghaei, Hao Tran, Jorge Silva, Barry H. Greenberg, Denise Barnard, Eric Adler
The VAD Journal
Background:
Prior studies have found that caregivers of chronically ill patients, including those with heart failure, have significant stress and burden. Ventricular Assist Devices (VADs) are a promising therapeutic modality for end stage heart failure. However, caregiver burden has not previously been studied in the caregivers of VAD patients.
Methods:
We studied 31 caregivers of VAD patients receiving care at University of California, San Diego. Validated instruments tools, such as the Bakas Caregiving Outcomes scale and Oberst Caregiving Demand and Difficulty sub-scales, were used to measure the caregivers’ psychological burden.
Results:
Nearly half of the caregivers were the patient’s spouse …
Normal Lactate Dehydrogenase Does Not Exclude Pump Thrombosis In Left Ventricular Assist Devices, Julie Shelton Do, Bennet George Md, Amanda Hart Bsn, Rn, Maya Guglin Md
Normal Lactate Dehydrogenase Does Not Exclude Pump Thrombosis In Left Ventricular Assist Devices, Julie Shelton Do, Bennet George Md, Amanda Hart Bsn, Rn, Maya Guglin Md
The VAD Journal
Left ventricular assist device (LVAD) pump thrombosis is a well-known complication of LVAD placement. Elevated lactate dehydrogenase (LDH) has classically been the first objective marker of pump thrombosis. In this case, we present a patient found to have normal serum LDH values but was ultimately found to have significant pump thrombosis.
Outcomes Of External Repair Of Heartmate Ii™ Lvad Percutaneous Leads, Jay D. Pal, Claudius Mahr, Jason W. Smith, Todd F. Dardas, Jay Pinette, David J. Farrar, Nahush A. Mokadam
Outcomes Of External Repair Of Heartmate Ii™ Lvad Percutaneous Leads, Jay D. Pal, Claudius Mahr, Jason W. Smith, Todd F. Dardas, Jay Pinette, David J. Farrar, Nahush A. Mokadam
The VAD Journal
Background: The HeartMate II Left Ventricular Assist Device (LVAD) receives power via a percutaneous lead connected to an external controller and batteries. At times, this lead can be damaged during normal wear, as well as by traumatic fracture, which may jeopardize the functionality of the LVAD. If there is significant internal damage, surgical replacement of the LVAD is required. However it is possible to repair externally damaged leads by replacing the distal portion of the lead to avoid pump replacement. We report the overall experience and outcomes in patients with external lead repairs.
Methods: A procedure for full …

The VAD Journal
This manuscript describes a protocol at the University of Kentucky that allows a translational research team to collect human myocardium that can be used for biological research. We have gained a great deal of practical experience since we started this protocol in 2008, and we hope that other groups might be able to learn from our endeavors. To date, we have procured ~4000 samples from ~230 patients. The tissue that we collect comes from organ donors and from patients who are receiving a heart transplant or a ventricular assist device because they have heart failure. We begin our manuscript by …
The Utility Of Remote Hemodynamic Monitoring Devices In Patients With A Ventricular Assist Device, Bennet George, Amanda Hart, Sarah Branam, Maya Guglin
The Utility Of Remote Hemodynamic Monitoring Devices In Patients With A Ventricular Assist Device, Bennet George, Amanda Hart, Sarah Branam, Maya Guglin
The VAD Journal
Remote intracardiac hemodynamic monitoring is a growing area of interest to help aid in the management of patients with chronic congestive heart failure. The utility of remote hemodynamic monitoring has not previously been investigated with a ventricular assist device population. We present two cases of patients with ventricular assist devices in which we employed remote hemodynamic monitoring data to aid in patient management.

Bleeding And Thromboembolic Events In Patients With Heartmate Ii Mechanical Circulatory Support, Salman Allana, Carrie Chapman, Nancy Sweitzer, Maryl Johnson, Takushi Kohmoto, Margaret Murray, David Murray, Zhanhai Li, Peter S. Rahko
The VAD Journal
Background: Bleeding and thromboembolic events (TE) are common complications following HeartMate II (HMII) implantation. The aim of the study was to review our experience related to bleeding and TE events in patients with a HMII and identify factors associated with increased risk of these events.
Methods: We retrospectively reviewed 70 consecutive patients who received a HMII between May 2006 and December 2011. The patients were followed for 12 months or until cardiac transplantation, device explantation or death. Major bleeding was defined by INTERMACS criteria with intracranial bleeding events added.
Results: There were 48 bleeding events in 28 (40%) patients with …

The VAD Journal
Background: Driveline infections (DLI) are a significant cause of morbidity and mortality in ventricular assist device (VAD) recipients. We compared driveline infection (DLI) rate after an institutional change in driveline management protocol.
Methods: We retrospectively reviewed records of left VAD recipients at our institution, based on driveline management. Group 1: daily driveline dressing change consisting of chlorhexidine cleansing, sterile 4x4 gauze, and use of an abdominal binder. Group 2: Dressing change every 3 days consisting of chlorhexidine cleansing, non-sterile silver-impregnated foam with overlying clear dressing, and use of a driveline anchor. Follow-up was censored at first DLI, device removal, transplant …
