Late Cardiotoxicity From The Tyrosine Kinase Inhibitor, Dasatinib: Pleural Effusions, Pulmonary Arterial Hypertension, And Right Heart Failure, Mark Jay Zucker, Andrew M. Zucker

The VAD Journal

Despite the remarkable progress made over the past few decades in the management of patients with both solid and hematologic malignancies, radiation- and chemotherapy-related cardiotoxicity remains an ongoing problem. This is true even for newer highly targeted therapies, including tyrosine kinase inhibitors (TKIs). This report presents a case of late/severe right heart dysfunction secondary to pulmonary hypertension, developed after ten years of therapy with dasatinib. We also review the history of this known, but often unrecognized, and potentially reversible complication, and we suggest treatment options. Additionally, this case highlights the remarkable effectiveness of TKIs in patients with chronic myelogenous leukemia …

Presentations

We discuss the case of a 13-month-old previously healthy male who presented with acute liver failure (ALF) of unknown etiology. He progressed to fulminant cardiopulmonary failure requiring mechanical ventilation and high dose inotropes with persistent lactate >20. He was cannulated to VA ECMO and tandem continuous renal replacement therapy (CRRT) with single pass albumin dialysis (SPAD) and plasma exchange (PLEX) therapies. He required high dose inotropes on ECMO and had persistently elevated lactate despite maximal medical therapy. Limited imaging studies suggested cirrhotic liver and possible intestinal pneumatosis. Due to evidence of fulminant ALF and potential for a reversible process, he …
