Outflow Graft Tamponade: An Underrecognized Cause of Obstruction.
Left ventricular assist device (LVAD) outflow graft obstruction can result in severe clinical deterioration. Underlying mechanisms may vary depending on the location. Outflow graft tamponade due to external compression can be under recognized. Management of this complication varies across institutions and a uniform approach has yet to be elucidated. ⋯ Conclusions: Outflow graft tamponade is a form outflow graft obstruction with a variable presentation that can result in significant hemodynamic compromise. It is amenable to both surgical and percutaneous interventions that restore LVAD function.

Observational StudyAssessment of Perioperative Protamine Reactions in Patients With Fish Allergies: A Retrospective Observational Study.
To retrospectively assess the incidence and severity of perioperative protamine reactions in adult patients with documented history of fish allergy. ⋯ The study findings suggest that in patients with a history of fish allergy, cross-reactivity with protamine is unlikely, as anaphylaxis and/or protamine reactions were rare in this patient population in the perioperative environment. Based on these findings, this study does not recommend avoiding protamine solely based on a history of fish allergy when heparin reversal is required during surgery.
