Mitral valve prolapse (MVP) is a common and predominantly benign condition; however, occasional reports of cardiac arrest in individuals with MVP have raised concern for a malignant subtype. The risk of sudden cardiac arrest in MVP is twice as high as that in the general population. The exact aetiology and risk predictors are elusive, but identification is necessary, if we are to protect patients at risk for cardiac arrest. This report highlights cardiac arrest as the initial presenting symptom of MVP. Rapid initiation of bystander cardiopulmonary resuscitation and time to first shock are key predictors of prognosis. Better screening to identify individuals with malignant phenotypes may aid in reducing the morbidity and mortality in patients with a predisposition for life-threatening arrhythmias.

Introduction: Accurate prognostication in comatose survivors of cardiac arrest is a challenging and high-stakes endeavor. We sought to determine whether internal EEG subparameters extracted by the Bispectral Index (BIS) monitor, a device commonly used to estimate depth-of-anesthesia intraoperatively, could be repurposed to predict recovery of consciousness after cardiac arrest.
Methods: In this retrospective cohort study, we trained a 3-layer neural network to predict recovery of consciousness to the point of command following versus not based on 48 hours of continuous EEG recordings in 315 comatose patients admitted to a single US academic medical center after cardiac arrest (Derivation cohort: N=181; Validation cohort: N=134).
The Effect of Fatigue During Search and Rescue Efforts in Debris on The Quality of Cardiopulmonary Resuscitation.
Prehosp Emerg Care

Occupational Therapy Program, Health Services Vocational School, Artvin Çoruh University.
Objectives: Cardiopulmonary resuscitation (CPR), which is used in cases of life-threatening cardiopulmonary arrest, is a physically exhausting procedure. Adding to that, sometimes, even before performing CPR, interventions to rescue the injured person from a challenging environment have caused significant fatigue. In this study, taking a novel research approach, we generated a scenario of fatigue during a rescue from earthquake debris and aimed to measure the effect of that fatigue on the quality of CPR performed by paramedics.

Department of Emergency Medicine, College of Medicine, The University of Arizona, Tucson, AZ.
Objectives: Buprenorphine is becoming a key component of prehospital management of opioid use disorder (OUD). It is unclear how many prehospital patients might be eligible for buprenorphine induction, as traditional induction requires that patients first have some degree of opioid withdrawal. The primary aim of this study was to quantify how many patients developed precipitated withdrawal after receiving prehospital naloxone for suspected overdose, as they could be candidates for prehospital buprenorphine.

Background: The impact of systemic inflammation in acute myocardial infarction complicated by cardiogenic shock (AMI-CS) is still a matter of debate. The present ECLS-SHOCK sub-study investigates the association of C-reactive protein (CRP) levels with short-term outcomes in patients with AMI-CS.
Methods: Patients with AMI-CS enrolled in the multicenter, randomized ECLS-SHOCK trial between 2019 and 2022 were included.
Preservation of Cardiac Xenografts in a Model of Infant Human Cardiac Transplantation.
Xenotransplantation
January 2025
Division of Cardiac Surgery, Department of Surgery, Children's Hospital of Los Angeles, Los Angeles, California, USA.
Introduction: There is no standard protocol for management of organ preservation for orthotopic, life-sustaining cardiac xenotransplantation, particularly for hearts from pediatric sized donors. Standard techniques and solutions successful in human allotransplantation are not viable. We theorized that a solution commonly used in reparative cardiac surgery in human children would suffice by exploiting the advantages inherent to xenotransplantation, namely the ability to reduce organ ischemic times by co-locating the donor and recipient.
