Outcomes Following Shock Aortic Valve Replacement: Transcatheter Versus Surgical Approaches.

Objectives: To compare transcatheter aortic valve replacement (TAVR) with surgical aortic valve replacement (SAVR) for patients in shock.

Background: There are minimal data on the clinical and echocardiographic outcomes for patients in shock that undergo TAVR and no data comparing these outcomes to similar patients undergoing SAVR.

Methods: This is a single center, retrospective cohort study of patients having Society of Thoracic Surgeons (STS)-defined urgent or emergent AVR for aortic stenosis with clinical signs and symptoms of shock.

Cerebral Oximetry as a Real-Time Monitoring Tool to Assess Quality of In-Hospital Cardiopulmonary Resuscitation and Post Cardiac Arrest Care.

Background: Regional cerebral oxygen saturation (rSO2) as assessed by near infrared frontal cerebral spectroscopy decreases in circulatory arrest and increases with high-quality cardiopulmonary resuscitation. We hypothesized that higher rSO2 during cardiopulmonary resuscitation and after return of spontaneous circulation (ROSC) would predict survival to discharge and neurological recovery.

Methods And Results: This prospective case series included patients experiencing in-hospital cardiac arrest.

Acute myocardial infarction.

This article discusses the approach to the management of myocardial infarction (MI) in the intensive care unit setting. It includes an overview of the definition, classification, and underlying pathologic conditions of acute MI and specifically discusses the diagnosis and management of unstable angina, non-ST elevation MI, and ST-segment elevation MI. Diagnosis and treatment of the acute complications of MI are also reviewed.
