Common misconceptions and mistakes • Left-sided heart failure (LHF) causes pulmonary hypertension and right-sided heart failure (RHF) as a result of “back pressure” • Pulmonary hypertension and right ventricle (RV)…
Common misconceptions and mistakes • Believing that reading a chest x-ray (CXR) requires advanced training, experience, and/or a “special eye” • Declaring a “blunted costophrenic angle” when the entire diaphragm…
Common misconceptions and mistakes • Believing that the most common cause of pulmonary hypertension (PH) in patients with severe lung disease is group 3 • Obtaining an nonexpert right-sided heart…
Common misconceptions and mistakes • Believing that a significant bronchodilator response on PFTs equals a diagnosis of asthma • Obtaining pulmonary function testing (PFT) during an acute illness involving cardiopulmonary…
Common misconceptions and mistakes • Hypoxemia is a common cause of dyspnea • Hypoxemia is a common cause of exercise limitation in patients with chronic obstructive pulmonary disease (COPD) •…
Common misconceptions and mistakes • Hypoxemia is a significant cause of dyspnea • A cutaneous O 2 sat ≥ 92% predicts adequate oxygenation and is the appropriate target for O…
Common misconceptions and mistakes • 100% O 2 sat is reassuring with regard to impending respiratory failure in a tachypneic, dyspneic patient • Hypercapnic respiratory failure is ruled out by…
Background In this study, the functionality of echocardiographic particle imaging velocimetry (E-PIV) was compared with that of digital particle imaging velocimetry (D-PIV) in an in vitro model. In addition, its…
Background The recent development of accurate methods to measure two-dimensional strain during dobutamine stress echocardiography has reactivated the debate as to the respective value of myocardial perfusion versus myocardial function…
Mechanical aortic prosthesis dysfunction can result from thrombosis or pannus formation. Pannus formation usually restricts systolic excursion of the occluding disk, resulting in progressive stenosis of the aortic prosthesis. Intermittent…
