Right ventricular (RV) failure occurs when the RV fails to maintain enough blood flow through the pulmonary circulation to achieve adequate left ventricular filling. This can occur suddenly in a previously healthy heart due to massive pulmonary embolism or right-sided myocardial infarction, but many cases encountered in the intensive care unit involve worsening of compensated RV failure in the setting of chronic heart and lung disease. Management of RV failure is directed at optimizing right-sided filling pressures and reducing afterload. ⋯ Systemic systolic arterial pressure should be kept close to RV systolic pressure to maintain RV perfusion. When these efforts fail, the judicious use of inotropic agents may help improve RV contractility enough to maintain cardiac output. Extracorporeal life support is increasingly being used to support patients with acute RV failure who fail to respond to medical management while the underlying cause of their RV failure is addressed.

Review Meta Analysis
Extracorporeal life support for acute respiratory failure. A systematic review and metaanalysis.
Extracorporeal life support (ECLS) for acute respiratory failure has increased as a result of technological advancements and promising results from recent studies as compared with historical trials. ⋯ ECLS was not associated with a mortality benefit in patients with acute respiratory failure. However, a significant mortality benefit was seen when restricted to higher-quality studies of venovenous ECLS. Patients with H1N1-acute respiratory distress syndrome represent a subgroup that may benefit from ECLS. Future studies are needed to confirm the efficacy of ECLS as well as the optimal configuration, indications, and timing for adult patients with respiratory failure.

Review
Will Choosing Wisely® improve quality and lower costs of care for patients with critical illness?
In 2009, a group of experts convened by the Institute of Medicine estimated that 30% of health care costs amounted to waste, including a substantial share from nonbeneficial and often harmful services. Professional organizations and medical ethicists subsequently called on specialty groups to generate "top five" lists of expensive tests or treatments without known benefits. Responding to this call, the American Board of Internal Medicine launched its Choosing Wisely campaign, with the top-five Choosing Wisely lists for pulmonary medicine and critical care released in 2014. ⋯ Although the campaign addresses some limitations of past efforts to improve quality and reduce waste, we believe it will do little to change provider behavior. Even if the top-five list for critical care were to change the behavior of providers, its ultimate impact on costs and quality will be lower than anticipated. Here we suggest several strategies for stakeholders to increase the impact of the critical care top-five list, and further discuss that despite limitations of the campaign it is still imperative for advancing best practice in critical care.

Transbronchial needle aspiration (TBNA) remains an invaluable diagnostic tool in the evaluation of mediastinal and hilar abnormalities, specifically in the evaluation of patients with lung cancer. Training in TBNA has remained integral in pulmonary fellowship programs, but unfortunately the training methods, volumes, and outcomes have been variable. ⋯ However, with this new technology, many questions have surfaced regarding training methods, volumes, and who should receive training. Within this context, we describe the history, current state, and future directions of the education of TBNA during pulmonary fellowship training.
