Development of Multidisciplinary Anticoagulation Management Guidelines for Patients Receiving Durable Mechanical Circulatory Support.

ABSTRACT: Patients receiving durable mechanical circulatory support (MCS) require life-long anticoagulation with a vitamin K antagonist (VKA). Due to alternations in hemostasis, concomitant therapy with antiplatelet agents and critical illness, they are at increased risk of thromboembolic and bleeding complications compared with the general population managed on VKAs. To prevent thrombotic events, current guidelines recommend that patients with MCS receive long-term anticoagulation with a VKA to maintain a target international normalized ratio (INR) as specified by device manufacturers, but limited data exist regarding specific routine management of anticoagulation therapy and its potential complications. To optimize anticoagulation management and minimize risk in these patients, we have centralized anticoagulation management in a collaborative approach between the inpatient hemostatic and antithrombotic (HAT) stewardship service and between ambulatory anticoagulation management service (AMS) and the advanced heart disease team. Patients are followed by these three services beginning when the device is implanted and extending the duration that patients have the device. The teams include multiple clinicians from cardiac surgery, cardiology, hematology, pharmacy, nursing, case management, nutrition, and psychiatry, therefore, in order to standardize practice among clinicians without compromising patient centered decision making, we assembled an interdisciplinary team to create multiple treatment guidelines. In addition to a centralized and collaborative approach, our guidelines ensure seamless transitions of care between the inpatient and outpatient settings. We believe our approach has demontrated a positive improvement in the care of these challenging patients. In this article, we present our comprehensive centralized anticoagulation management approach for patients with left ventricular assist systems (LVAS).

Project description:Durable mechanical circulatory support (MCS) devices revolutionized the treatment options for patients with end-stage heart failure (HF). Implantation of durable mechanical support has become an integral treatment modality in end-stage HF patients and it is associated with improved quality of life and survival. There is no doubt that this needs an interdisciplinary and interprofessional approach of cardiac surgeons, cardiologists, cardiac anesthesiologists, perfusionists, intensivists, psychologists, assist device coordinators as well as physiotherapists and intensive care. Implantation of durable MCS is a challenging procedure for the anesthesiologist due to the patient's characteristics and comorbid diseases. It demands comprehensive training, high vigilance and quick response during the acute hemodynamic changes occurring during the surgery. Preoperative risk stratification is of major importance to guide perioperative medical treatment strategies. Most of these patients have several comorbidities and multiple medications. Therefore, to anticipate postoperative end-organ dysfunction such as cognitive dysfunction, pulmonary or renal failure, an interdisciplinary approach is necessary to optimize patient's prior surgery. Transthoracic and transesophageal echocardiography (TTE and TEE), both play an invaluable role in diagnosing the cause and guiding the management in different unstable clinical situations. Especially prevention of postoperative right HF with subsequent necessity of temporary MCS is important as it is associated with higher mortality. The aim of this review is to provide an overview about the current concepts of perioperative management for durable MCS. A multimodal standard operating procedure supports early recovery after surgery and intensive care stay. Standardized perioperative care helps to ensure optimal medical treatment. This review focusses on several major skills of perioperative management of these high-risk surgical patients.
