Right Ventricular Failure after Left Ventricular Assist Device Placement —Have We Finally Arrived at the Crux of the Matter?
Pre-left ventricular assist device (LVAD) risk stratification is integral in identifying patients predisposed to right ventricular failure (RVF).1 To date, clinical scoring models such as the Michigan Risk Score in conjunction with specific hemodynamic parameters obtained from the preoperative right heart catheterization, including central venous pressure (CVP), CVP/pulmonary capillary wedge pressure, and right ventricular stroke work index, have been the cornerstone of post-LVAD RVF risk stratification.

Predicting Fluid Responsiveness During Infrarenal Aortic Cross-Clamping in Pigs
Objective: Infrarenal aortic cross-clamping (ACC) induces hemodynamic disturbances that may affect respiratory-induced variations in stroke volume and, therefore, affect the ability of dynamic parameters such as pulse-pressure variation (PPV) to predict fluid responsiveness. Since this issue has not been investigated yet to authors’ knowledge, the hypothesis was tested that ACC may change PPV and impair its ability to predict fluid responsiveness.Design: Prospective laboratory experiment.Setting: A university research laboratory.Participants: Nineteen anesthetized and mechanically ventilated pigs.Interventions: Two cours...

Arterial Closure Devices for Treatment of Inadvertent Large-Caliber Catheter Insertion Into the Subclavian or Carotid Artery: A Case Series of Five Patients
CENTRAL VENOUS CATHETERIZATION is a common procedure in today`s medicine. Iatrogenic complications occur in up to 34% of catheter placements including 5% of arterial puncture. A variety of complications by arterial puncture have recently been described, including airway obstruction, pseudoaneurysms, arteriovenous fistulas, and even stroke caused by arterial thrombosis or embolization. Although 2-D ultrasound assisted insertion of large central venous catheters may reduce adverse events, it might not be available in an emergency setting, and the use of ultrasound guidance requires training. Depending on anatomic localizatio...
