Anesthetic and Perioperative Considerations for Convergent Procedure for Atrial Fibrillation: A Retrospective Observational Cohort Study.
To summarize anesthetic and perioperative considerations in patients undergoing the convergent procedure for atrial fibrillation (AF). ⋯ This retrospective analysis of medical records showed that many patients with recurrent AF presenting for convergent procedure carry a burden of multiple comorbidities (eg, obesity, obstructive sleep apnea), and history of unsuccessful ablations. Multistage multidisciplinary convergent procedure might be lengthy and potentially complicated and requires meticulous preparation (eg, endotracheal intubation, lung isolation, advanced cardiac monitoring, central venous access) to ensure optimal outcomes. Anesthesiologists and perioperative physicians should tailor their approach to this multimorbid population while anticipating perioperative respiratory events, rapid hemodynamic shifts, blood loss, and the possibility of CPB.

Association Between Pulmonary Artery Pulsatility Index and Radial Artery Pulse Pressure and Successful Separation from Peripheral Veno-Arterial Extracorporeal Membrane Oxygenation: A French Single-Center Retrospective Study From 2017 to 2021.
Few reliable tools exist to predict weaning patient outcomes from venoarterial extracorporeal membrane oxygenation (ECMO; VA-ECMO). Pulmonary artery pulse pressure indexed on right atrial pressure (PAPi) reflects the ventricle-pulmonary coupling and may be representative of right ventricular recovery. Radial artery pulse pressure (rPP) may be representative of left ventricular recovery. We intended to explore the usefulness of these indices in the weaning from VA-ECMO. ⋯ Higher PAPi and rPP were predictors of successful weaning from VA-ECMO in this retrospective study.

Prebypass Critical Closing Pressure Predicts Acute Kidney Injury After Cardiopulmonary Bypass.
Optimal blood pressure goals during cardiopulmonary bypass (CPB) remain uncertain and new metrics to individualize perfusion targets are needed. Critical closing pressure (Pcrit) is a fundamental property of the arterial circulation related to vascular tone and represents the outflow pressure impacting flow across the systemic circulation. We examined Pcrit as a prognostic marker of acute kidney injury (AKI). ⋯ A higher prebypass Pcrit is associated with a significantly higher incidence of postoperative AKI. Future study is warranted to investigate using intraoperative Pcrit to determine a personalized blood pressure goal during CPB.
