The left ventricular assist device: a literature review and guidelines for dental care.

About 6.2 million adults in the United States suffer from heart failure (HF). For patients with advanced HF refractory to medical therapy, an orthotopic heart transplant or a ventricular assist device (VAD) is the only long-term survival option. The most commonly used form of these devices is the left VAD (LVAD), implanted to support the left ventricle. As many as 2754 LVADs were implanted annually between 2006 and 2015, allowing recipients to maintain a relatively normal lifestyle, including both elective and emergency dental care in the ambulatory setting. As more LVADs are implanted, oral healthcare providers (OHCPs) are more likely to encounter these patients in an outpatient clinical setting. This study aims to educate OHCPs on the specific needs of these patients and to begin development of clinical guidelines for their dental management. A literature review using electronic resources was conducted to identify all literature relevant to the clinical topic. Appropriate literature was selected based on established inclusion and exclusion criteria, and 3 articles published between 2015 and 2020 were identified. None offered clinical practice guidelines for the care of patients with implanted LVADs. However, it is known that patients supported by an LVAD are at higher risk of thrombotic complications, which can lead to pump system failure and embolic stroke. To reduce the risk of complications, these patients are treated with anticoagulation therapy. Interruption of these drugs prior to dental treatment is not recommended. Due to the side effects of anticoagulation therapy and acquired coagulopathy, patients with an LVAD are also at increased risk of bleeding events. Thus, perioperative hemorrhagic risk during routine oral surgical procedures must be considered. While most dental care can be done in an outpatient setting, OHCPs should be aware of the special needs of these patients and provide appropriate care through close coordination with the LVAD/transplant team.
