“… 9 Collapse of the right ventricular free wall in diastole is highly specific, and is the most recognized sonographic sign of cardiac tamponade. 10 This is demonstrated by placing M-mode over the mitral valve in the parasternal long-axis view ( Images 2A and 3A ) and observing movement of the right ventricular free wall towards the intra-ventricular septum as the mitral valve opens in early diastole ( Image 3B ).…”

“…One retrospective review found that the majority of patients who present with subacute non-traumatic cardiac tamponade will not be hypotensive (15%), but actually normotensive (50%) or even hypertensive (35%). 10 The existing literature suggests that the incidence of patients with sonographic cardiac tamponade who are hypertensive ranges between 27% to 43%. 12 – 15 Preexisting hypertension, 14 – 15 and advanced renal disease, 14 both of which are present in our patient, are risk factors for developing sonographic cardiac tamponade without hypotension.…”

Minoxidil is a strong oral vasodilator that is used to treat patients with hypertension refractory to first-line medications. We report a case of minoxidil-associated subacute cardiac tamponade diagnosed by point-of-care ultrasound (POCUS) in a hypertensive patient. A 30-year-old male with a past medical history of poorly controlled hypertension (treated with minoxidil) and chronic kidney disease presented with 2–3 days of chest pain and shortness of breath with markedly elevated blood pressures. A point-of-care transthoracic echocardiogram revealed a massive pericardial effusion with sonographic tamponade physiology. We review the risk factors for developing pericardial effusions that progress to cardiac tamponade, the utility of diagnosing these patients by POCUS, and the incidence of patients who present with sonographic signs of cardiac tamponade without hypotension.

“…Motion Mode (M-Mode) : A sequence of two dimensions with time on the horizontal axis and tissue depth on vertical axis follow each other and help in the detection of movement of organ boundaries as the depth from the probe changes in moving organs. This has good applications in the emergency setting to diagnose pneumothorax, left ventricular systolic function, cardiac tamponade, and hypertrophic obstructive cardiomyopathy [10].…”

This article reviews the use of thoracic ultrasound in the intensive care unit (ICU). The focus of this article is to review the basic terminology and clinical applications of thoracic ultrasound. The diagnostic approach to a breathless patient, the blue protocol, is presented in a simplified flow chart. The diagnostic application of thoracic ultrasound in lung parenchymal and pleural diseases, role in bedside procedures, diaphragmatic assessment, and lung recruitment are described. Recent updates discussed in this review help support its increasingly indispensable role in the emergent and critical care setting.

“…We have read the letter by Blanco et al in the Journal and appreciate being given the opportunity to respond (1). The authors state that they enjoyed our article but question our assertion that M-mode has high clinical utility and feel that experienced physicians do not need to waste extra time performing these types of evaluations for the majority of point of care ultrasound scans in the emergency department (ED).…”
