Carpentier classification of mitral valve regurgitation

The Carpentier classification divides mitral valve regurgitation into three types based on leaflet motion 1: type I: normal leaflet motion annular dilation, leaflet perforation regurgitation jet directed centrally type II: excessive leaflet motion papillary muscle rupture, chordal rupture, ...

Right ventricular function (point of care ultrasound)

Right ventricular function is often measured in point-of-care ultrasonography as a composite of the right ventricular size, wall measurements, and contractile efforts.  Terminology The right ventricle (RV) can be anatomically divided into an inflow portion, an outflow portion, and an apex. Con...

A-line (ultrasound)

An A-line is an ultrasonographic artifact appreciated during the insonation of an aerated lung. 1 The term may be applied to the horizontal, echogenic long path reverberation artifacts that occur beneath the pleural line at multiples of the distance between the ultrasound probe and the visceral...

Pleural effusion volume (ultrasound)

Measurement of a pleural effusion volume with point-of-care ultrasonography may be a useful tool for intensivists and is an active area of research in critical care 7. In controlled settings ultrasound may detect constitutive pleural fluid, can reliably detect effusions >20 mL in clinical setti...

Raised intracranial pressure

Raised intracranial pressure is a pathological increase in the intracranial pressure and is a medical emergency.  Clinical presentation The symptoms and signs of raised intracranial pressure are often non-specific and insidious in onset: headache drowsiness anorexia visual disturbances bl...

Beads on a string sign (chronic salpingitis)

The beads-on-a-string sign is used to refer to the classic morphologic changes in the Fallopian tubes as a result of chronic salpingitis.    Terminology The "string" alludes to the notably thin salpingeal wall, while the hyperechoic mural nodules constitute the "beads" 1. Radiographic feature...

B-line (ultrasound)

The B-line is an artifact relevant in lung ultrasonography. As originally described, it has seven defining features 1: a hydroaeric comet-tail artifact arising from the pleural line hyperechoic well-defined extending indefinitely erasing A-lines  moving in concert with lung sliding, if lung...
Article

Submassive pulmonary embolism

A submassive pulmonary embolism refers to an acute pulmonary embolism with evidence of myocardial necrosis or right ventricular dysfunction in the absence of systemic hypotension. An elevation in troponin I or T provides evidence of myocardial necrosis. Right ventricular dysfunction is defined b...

McConnell's sign (echocardiography)

The McConnell's sign describes a regional pattern of acute right ventricular dysfunction on transthoracic echocardiography first observed in a cohort of patients with acute pulmonary thromboembolism. In contrast to the global wall motion abnormalities observed in chronic right ventricular dysfun...

Transthoracic echocardiography

Standard transthoracic echocardiography (TTE) is the most commonly performed form of echocardiography. It consists of five standardized windows which are obtained in a standardized sequence 1. Obtaining views from the left parasternal, apical, subcostal, and suprasternal notch windows is mandato...
Article

Peritoneal stripe sign (pneumoperitoneum)

The peritoneal stripe sign in abdominal ultrasonography is considered indicative of intraperitoneal free air, present in pneumoperitoneum. Free air in the abdomen will collect in an anti-dependent manner, typically the anterior prehepatic space in the supine patient, settling against the parieta...
Article

Diastolic dysfunction (point of care ultrasound)

Assessment for diastolic dysfunction is an advanced application of point-of-care ultrasonography, most commonly used as a supplemental non-invasive estimate of left atrial pressure in hemodynamically complex patients 1. Of note, this article will discuss the simplified, binary approach used in c...
Article

Pulsatility index (ultrasound)

The pulsatility index (PI) (also known as the Gosling index) is a calculated flow parameter in ultrasound, derived from the maximum, minimum, and mean Doppler frequency shifts during a defined cardiac cycle. Along with the resistive index (RI), it is typically used to assess the resistance in a ...

Plankton sign (ultrasound)

The plankton sign refers to swirling, punctiform internal echoes within an otherwise anechoic pleural effusion which demonstrate slow, whirling dynamics, occasionally buffered by cardiac and respiratory impulses. When present, one may rule out a transudative effusion, and should be highly suspic...
