Supraglottic Airway Use for Transfemoral-Transcatheter Aortic Valve Replacement

Optimizing Anesthetic Selection in Transcatheter Aortic Valve Replacement: Striking a Delicate Balance between Efficacy and Minimal Intervention

Patients with severe calcific native aortic valve stenosis (AS) who require valve replacement have two options, surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). TAVR was approved in late 2011 for extremely high-risk patients and was subsequently approved for high-risk (2012), intermediate-risk (2016), and low-risk (2019) patients. In 2019, TAVR procedures surpassed SAVR procedures for the first time in the United States. The approach to anesthesia for this procedure has also evolved. Initially, general anesthesia (GA) was preferred, but currently, conscious sedation (CS) is favored. This review aims to clarify the indications and contraindications for both approaches, as well as the advantages of one approach over the other. Recent studies show that conscious sedation has better outcomes in terms of all-cause mortality, procedure complications such as stroke, myocardial infarction, infection requiring antibiotics, acute kidney injury, and the need for inotropes or vasopressors.

EACTA/SCA Recommendations for the Cardiac Anesthesia Management of Patients With Suspected or Confirmed COVID-19 Infection: An Expert Consensus From the European Association of Cardiothoracic Anesthesiology and Society of Cardiovascular Anesthesiologists With Endorsement From the Chinese Society of Cardiothoracic and Vascular Anesthesiology

The European Association of Cardiothoracic Anaesthesiology (EACTA) and the Society of Cardiovascular Anesthesiologists (SCA) aimed to create joint recommendations for the perioperative management of patients with suspected or proven severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection undergoing cardiac surgery or invasive cardiac procedures.

To produce appropriate recommendations, the authors combined the evidence from the literature review, reevaluating the clinical experience of routine cardiac surgery in similar cases during the Middle East Respiratory Syndrome (MERS-CoV) outbreak and the current pandemic with suspected coronavirus disease 2019 (COVID-19) patients, and the expert opinions through broad discussions within the EACTA and SCA. The authors took into consideration the balance between established procedures and the feasibility during the present outbreak. The authors present an agreement between the European and US practices in managing patients during the COVID-19 pandemic.

The recommendations take into consideration a broad spectrum of issues, with a focus on preoperative testing, safety concerns, overall approaches to general and specific aspects of preparation for anesthesia, airway management, transesophageal echocardiography, perioperative ventilation, coagulation, hemodynamic control, and postoperative care.

As the COVID-19 pandemic is spreading, it will continue to present a challenge for the worldwide anesthesiology community. To allow these recommendations to be updated as long as possible, the authors provided weblinks to international public and academic sources providing timely updated data.

This document should be the basis of future task forces to develop a more comprehensive consensus considering new evidence uncovered during the COVID-19 pandemic.

Outcomes of Transfemoral Transcatheter Aortic Valve Replacement Performed With General Anesthesia Using a Supraglottic Airway Versus Monitored Anesthesia Care

OBJECTIVE

Compare general anesthesia with a supraglottic airway versus monitored anesthesia care for transfemoral transcatheter aortic valve replacement (TF-TAVR) in patients with aortic stenosis. The authors hypothesized that the supraglottic airway group would have similar operating room and procedure times, postanesthesia care unit (PACU) and hospital stays, and similar rates of intraprocedural and postprocedural complications compared with the monitored anesthesia care group.

STUDY DESIGN

Retrospective chart review with 1:1 propensity score matching of supraglottic airway to monitored anesthesia care patients.

SETTING

Tertiary care academic medical center.

PARTICIPANTS

TF-TAVR patients between 2017 and 2019.

INTERVENTIONS

Supraglottic airway or monitored anesthesia care.

MEASUREMENTS AND MAIN RESULTS

One hundred forty-eight supraglottic airway patients were matched with 148 monitored anesthesia care patients. Monitored anesthesia care patients had slightly shorter operating room (p < 0.001) and procedure times (p = 0.015). No difference was observed in hospital length of stay (p = 0.34). Fewer patients in the supraglottic airway group required a PACU stay >2 hours (p < 0.001). Use of intraprocedural vasopressors (p < 0.001) and fentanyl dosage (p < 0.001) was higher in the supraglottic airway group. No differences were observed in postoperative complications or procedural success rates.

CONCLUSIONS

In this, the first study to compare these 2 modalities, supraglottic airway use was demonstrated to be a safe, feasible alternative to monitored anesthesia care during TF-TAVR and did not increase organ-specific morbidity, 30-day mortality, hospital length of stay, or PACU length of stay. Even though supraglottic airway was associated with slight increases in procedure and operating room times, these were not clinically significant.
