The Heart Rhythm Society (HRS)/American Society of Anesthesiologists (ASA) Expert Consensus Statement on the Perioperative Management of Patients with Implantable Defibrillators, Pacemakers and Arrhythmia Monitors: Facilities and Patient Management: This document was developed as a joint project with the American Society of Anesthesiologists (ASA), and in collaboration with the American Heart Association (AHA), and the Society of Thoracic Surgeons (STS)

Maternal mortality is a major public health crisis in the United States. Cardiovascular disease (CVD) is a leading cause of maternal mortality and morbidity. Labor and delivery is a vulnerable time for pregnant individuals with CVD but there is significant heterogeneity in the management of labor and delivery in high-risk patients due in part to paucity of high-quality randomized data. The authors have convened a multidisciplinary panel of cardio-obstetrics experts including cardiologists, obstetricians and maternal fetal medicine physicians, critical care physicians, and anesthesiologists to provide a practical approach to the management of labor and delivery in high-risk individuals with CVD. This expert panel will review key elements of management from mode, timing, and location of delivery to use of invasive monitoring, cardiac devices, and mechanical circulatory support.

Beginning January 1, 2022, the Council on Accreditation is requiring student registered nurse anesthetists (SRNAs) matriculating into nurse anesthesia programs to track preanesthetic comprehensive history and physical (H&P) assessment completion numbers. This quality improvement (QI) project aimed to create a new clinical rotation for SRNAs to practice their preanesthetic H&P assessment skills through video telehealth.

A quality improvement project.

Likert-style and free-text surveys were administered to both the SRNA students and the expert provider to assess for improvements, viability, and effectiveness of the clinical rotation. SRNAs used a curated library of evidence-based resources and instructions for conducting their assessments. Expert guidance was provided through a single experienced provider.

Eight SRNAs performed one preanesthetic telehealth H&P assessment and four of the eight performed a second assessment. Pre-QI surveys indicated 75% were not comfortable with their ability in performing a competent assessment. Initial post-QI surveys indicated 88% were more comfortable with their abilities and 100% of those who completed a second-time post-QI survey 100% were more comfortable. Provider feedback indicated full-day clinical rotations were feasible and important.

Results revealed SRNAs desire and need for more preanesthetic comprehensive H&P appointments. Expansion into full-scale, full-day, and in-person assessments was also indicated. QI projects at other clinical sites can determine if similar rotations can also create similar clinical rotations.

An increasing number of patients undergoing elective or emergency surgery in the United States have a cardiovascular implantable electronic device. Practice advisories and consensus statements have been issued by the American Society of Anesthesiologists and the Heart Rhythm Society, advocating a multidisciplinary approach. Unfortunately, anesthesia providers often find themselves in a situation in which they are left to manage these devices independently. At the University of Washington Medical Center, an anesthesiology-based service to manage these devices has existed for more than a decade. Many problems with devices have been observed, including confusing rhythms, failure of magnets to provide the desired change in device function, and actual device malfunction. With these clinical case examples taken from the authors’ collective experience, this article provides an in-depth understanding of some key electrophysiology principles relevant to cardiovascular implantable electronic device function and appropriate perioperative management.

There is an increased frequency of patients with cardiac implantable electroic devices (CIEDs) who are undergoing surgical or interventional procedures. The function of a CIED may be affected by electromagnetic interference in the operating room which can threaten the safety and hemodynamic stability of patients. It is important for anesthesiologists to understand the perioperative approach for dealing with CIEDs. Perioperative management of CIEDs should include implementing an exact algorithm and/or developing a specific plan with an interdisciplinary team if necessary.

Heart failure and cardiomyopathy are significant contributors to pregnancy-related deaths, as maternal morbidity and mortality have been increasing over time. In this setting, the role of the multidisciplinary cardio-obstetrics team is crucial to optimizing maternal, obstetrical and fetal outcomes. Although peripartum cardiomyopathy is the most common cardiomyopathy experienced by pregnant individuals, the hemodynamic changes of pregnancy may unmask a pre-existing cardiomyopathy leading to clinical decompensation. Additionally, there are unique management considerations for women with pre-existing cardiomyopathy as well as for those women with advanced heart failure who may be on left ventricular assist device support or have undergone heart transplantation. The purpose of this review is to discuss: 1) preconception counseling; 2) risk stratification and management strategies for pregnant women extending to the postpartum “fourth trimester” with pre-existing heart failure or “pre–heart failure;” 3) the safety of heart failure medications during pregnancy and lactation; and 4) management of pregnancy for women on left ventricular assist device support or after heart transplantation.
