Mitral valve repair versus replacement

Pulmonary embolism remains a leading cause of cardiovascular mortality. Presentation and outcomes are variable among patients and require rapid risk stratification for assessment and prognosis, as well as selection of appropriate treatment. Over the past several decades, several different models and parameters have become available to assess risk and classify pulmonary embolism into different risk categories. Some patients may be candidates for early discharge or complete outpatient treatment, while some may require invasive diagnostics and intensive monitoring. In this review, we summarize contemporary guidelines and methods for classification and risk stratification in an effort to provide tools for physicians to use in their management of patients with acute pulmonary embolisms.

Extracorporeal membrane oxygenation (ECMO) has become an integral treatment option for patients as a bridge to transplant, management of post cardiotomy cardiogenic shock, and for rescue after cardiopulmonary arrest. Significant strides in ECMO technology and management cannot, however, replace the importance of maintaining and following a comprehensive safety checklist. We herein report a case of massive air entrainment from an inadvertently disconnected port of a central venous catheter (CVC) in the neck which culminated in an airlock of the ECMO circuit. Ascertaining the relative position of the tip of the CVC with respect to the venous cannula on chest X-ray, tightly securing all its ports, and appraising and educating the health-care team can prevent this rare but devastating complication of fatal air embolism.
