An experimental model of chronic severe mitral regurgitation.

Objective: To develop a minimally invasive, reproducible model of chronic severe mitral regurgitation (MR) that replicates the clinical phenotype of left atrial (LA) and left ventricular dilation and susceptibility to atrial fibrillation.

Methods: Under transesophageal echocardiographic guidance, chordae tendinae were avulsed using endovascular forceps until the ratio of regurgitant jet area to LA area was ≥70%. Animals survived for an average of 8.

Incidence and prediction of intraoperative and postoperative cardiac arrest requiring cardiopulmonary resuscitation and 30-day mortality in non-cardiac surgical patients.

Background: The incidence, prediction and mortality outcomes of intraoperative and postoperative cardiac arrest requiring cardiopulmonary resuscitation (CPR) in surgical patients are under investigated and have not been studied concurrently in a single study.

Methods: A retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program data between 2008 and 2012. Firth's penalized logistic regression was used to study the incidence and identify risk factors for intra- and postoperative CPR and 30-day mortality.

Intraoperative Assessment of Hepatic Vein Tracings in Constrictive Pericarditis During Surgical Pericardiectomy.

CONSTRICTIVE PERICARDITIS is characterized by progressive inflammation and fibrosis of the pericardium. It manifests with symptoms of heart failure. The only effective treatment is surgical pericardiectomy.

Anesthetic Considerations for Transcatheter Tricuspid Valve Repair.

The development of transcatheter approaches for heart valve repair and replacement procedures have revolutionized the field of structural cardiology and cardiac anesthesiology. With the recently reported benefits of transcatheter mitral repair procedures, there has been increasing focus on transcatheter tricuspid repair technologies. Currently, there are multiple transcatheter tricuspid repair devices that are undergoing feasibility testing, and each device has its own unique procedural considerations.

Anesthetic Considerations for Aortic Arch Stenting.

With advances in modern day imaging techniques for the aorta, there has been an increasing incidence of vascular diseases involving the aortic arch. Historically, the only treatment option for arch disease has been open arch replacement under circulatory arrest conditions with or without selective cerebral perfusion. However, this open procedure has significant morbidity and mortality, especially in elderly patients with multiple comorbidities.

Anesthetic Considerations for the Transcatheter Management of Mitral Valve Disease.

The development of transcatheter interventions to provide a minimally invasive alternative to open surgical repair has revolutionized the care of patients with valvular heart disease. Recently, this technology has been expanded to allow for the treatment of pathology of the mitral valve. This review discusses the anesthetic considerations for patients presenting for transcatheter management of mitral valve disease, including transcatheter mitral valve replacement (TMVR) and transcatheter mitral valve repair (TMVRep).

Anesthetic Considerations for Transcatheter Pulmonary Valve Replacement.

The introduction of transcatheter therapy for valvular heart disease has revolutionized the care of patients with valvular disorders. Pathologic regurgitation or stenosis of the pulmonary valve, right ventricular outflow tract, or a right ventricle-to-pulmonary artery conduit represent emerging indications for transcatheter therapy. To date, minimal literature exists detailing the anesthetic management of patients undergoing transcatheter pulmonary valve replacement.

Novel use of a noninvasive hemodynamic monitor in a personalized, active learning simulation.

The present study furthered the concept of simulation-based medical education by applying a personalized active learning component. We tested this novel approach utilizing a noninvasive hemodynamic monitor with the capability to measure and display in real time numerous hemodynamic parameters in the exercising participant. Changes in medical knowledge concerning physiology were examined with a pre-and posttest.
