Acute Decompensated Valvular Disease in the Intensive Care Unit.

Acute decompensated valvular disease encompasses a group of complex and challenging conditions, which are often the primary reason for admission to the cardiac intensive care unit and can also complicate the management of other primary cardiac disorders. Critically ill patients with valvular disease also present unique diagnostic and management challenges. Historically, medical and percutaneous interventional therapies have been limited and surgery was the only definitive treatment; however, surgical risk can at times be prohibitive. High-quality evidence to direct management of acute valvular disorders in this population is lacking and societal guidelines largely do not address treatment options for critically ill patients with decompensated valvular disease. In this review, we discuss the clinical presentation and epidemiology of commonly encountered valvular diseases in the modern cardiac intensive care unit, highlight key pathophysiology, detail gaps in evidence, describe the pivotal role of multidisciplinary Heart Teams, and provide guidance for management.
