Simultaneous Multi-Vascular Bed Imaging in a Patient Supported by a Continuous-Flow LVAD
Patients supported with left ventricular assist devices (LVADs) are burdened by frequent hemocompatibility-related adverse events related to patient-pump interactions. These predominantly vascular events include stroke, gastrointestinal bleeding, and pump thrombosis. Our center performs routine, invasive hemodynamic ramp speed titrations in LVAD patients to determine the optimal rotational speed after implantation. We sought to interrogate changes in vascular hemodynamics during an exercise ramp study to understand the influence of pump speed and exercise on outflow graft and cerebrovascular flow.

Aortic and Renal Artery Thrombosis as the First Clinical Manifestation of COVID-19 in a Heart Transplant Recipient
The relation between coronavirus 2019 disease (COVID-19) and thrombotic events is well established, and both arterial and venous thrombotic events are described. Although arterial events occur in about 3.6 to 10.5% of critically ill patients, they are usually stroke or acute myocardial infarction. Arterial thrombosis of other sites is rare.

Complications of left ventricular assist devices causing high urgency status on waiting list: impact on outcome after heart transplantation
ConclusionsLeft ventricular assist device therapy can impair the outcome after HTx. However, the occurrence of LVAD complications may not impact on outcome after HTx. Thus, we cannot support the prioritization or discrimination of HTx candidates according to distinct mechanical circulatory support ‐associated complications. Future allocation strategies have to respect that device‐related complications may define urgency but do not impact on the outcome after HTx.

Major Thromboembolic Complications in Liver Transplantation: The Role of Rotational Thromboelastometry and Cryoprecipitate Transfusion
Background. Although hemorrhage is a major concern during liver transplantation (LT), the risk for thromboembolism is well recognized. Implementation of rotational thromboelastometry (ROTEM) has been associated with the increased use of cryoprecipitate; however, the role of ROTEM-guided transfusion strategy and cryoprecipitate administration in the development of major thromboembolic complications (MTCs) has never been documented. Methods. We conducted a study on patients undergoing LT before and after the implementation of ROTEM. We defined MTC as intracardiac thrombus, pulmonary embolism, hepatic artery thromb...

Troubleshooting Left Ventricular Assist Devices: Modern Technology and Its Limitations
AbstractPurpose of reviewAs the incidence of heart failure continues to rise, modern generation left ventricular assist devices (LVADs) have become the primary therapeutic modality used as both bridge to transplant (BTT) and destination therapy (DT) in patients with acute and chronic heart failure. This review aims to highlight the progression of LVAD technology, outline LVAD complications and manifestations, and provide evidence-based therapeutic methods to troubleshoot such adverse events.Recent findingsDespite modern innovation, LVAD adverse events continue to hinder the progress of HF paradigms and are associated with ...

Myocardial infarction and factor VIII elevation in a 36-year-old man
We report a 36-year-old man who had a myocardial infarction despite lacking traditional cardiac risk factors. He developed end-stage heart failure and renal insufficiency necessitating a HeartMate II left ventricular assist device (LVAD). While on the transplant list, he experienced two episodes of LVAD thrombosis 6 months apart, prompting device exchange and escalation of anticoagulation therapy. He eventually underwent a successful heart-kidney transplant before suffering an extensive left lower extremity deep vein thrombosis 6 weeks later. A thrombophilia workup revealed elevated factor VIII activity of 319% (normal ran...

Liver Transplant in Hemoglobin SC Disease and Autoimmune Hepatitis: A Case Report
We report a case of a 50-year-old man with sickle cell disease genotype SC (HbSC) and cirrhosis secondary to autoimmune hepatitis who underwent liver transplant. His postoperative course included upper extremity deep vein thrombosis, pulmonary embolus, stroke via a patent foramen ovale after a line removal, and posterior reversible encephalopathy syndrome. Fortunately, he is alive with a functioning graft at 10 months after liver transplant. This case highlights the feasibility of liver transplant in sickle cell disease given the support of meticulous multidisciplinary care and the unique aspects of autoimmune hepatitis an...

Twelfth Interagency Registry for Mechanically Assisted Circulatory Support Report: Readmissions after LVAD
Ann Thorac Surg. 2022 Jan 7:S0003-4975(22)00007-8. doi: 10.1016/j.athoracsur.2021.12.011. Online ahead of print.ABSTRACTThe twelfth annual report from the Society of Thoracic Surgeons (STS) Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) highlights outcomes for 26,688 continuous-flow LVAD patients over the past decade (2011-2020). In 2020, we observed the largest drop in yearly LVAD implant volumes since the registry's inception, which reflects the effects of the COVID-19 pandemic on cardiac surgical volumes in the United States. The 2018 heart transplant allocation policy change in the U.S. ...
