Dilated cardiomyopathy

Dilated cardiomyopathy (DCM) is defined as left ventricular chamber dilation with decreased systolic function (FEVG <40%) in the absence of coronary artery disease or conditions which impose a chronic pressure overload. There may also be right ventricular dysfunction. Causes are related to intri...
Article

Ventricular septal defect

Ventricular septal defects (VSD) represent defects in the interventricular septum that allow a hemodynamic communication between the right and left ventricles. It typically results in a left-to-right shunt. Epidemiology They represent one of the most common congenital cardiac anomalies and may...
Article

Restrictive cardiomyopathy

Restrictive cardiomyopathy is the least common subtype of cardiomyopathy and is characterized by a marked decrease in ventricular compliance.  Clinical presentation Patients can present with symptoms and signs of left ventricular failure and/or right ventricular failure 9.  Pathology It is p...

Carcinoid heart disease

Carcinoid heart disease, also known as Hedinger syndrome, is a known complication of carcinoid tumors, and is particularly prevalent in patients who develop carcinoid syndrome. Epidemiology Cardiac lesions are present in approximately 50% of patients with carcinoid syndrome 1. Clinical presen...
Article

Fetal echocardiography views

A standard fetal echocardiogram consists of several specific views which can be obtained to optimize visualization of different structures and anomalies. They include: Basic views abdominal situs view / transverse view of abdomen four chamber view left ventricular outflow tract view (or a fi...

Arterial Doppler assessment in LVAD patients

In patients with a left ventricular assist device (LVAD), spectral Doppler waveforms are altered due to continuous flow provided by the pump in the device: waveforms are monophasic with a constant antegrade flow and no flow below the baseline. the waveform is typically parvus-tardus with a slo...

Non-compaction of the left ventricle

Non-compaction of the left ventricle, also known as spongiform cardiomyopathy or left ventricular non-compaction (LVNC) is a phenotype of hypertrophic ventricular trabeculations and deep interventricular recesses. It has been hypothesized to result from arrest of normal myocardial compaction dur...
Article

Takotsubo cardiomyopathy

Takotsubo cardiomyopathy (TC) is a condition characterized by transient regional abnormal cardiac wall motion, not defined to a single coronary arterial territory. It has been described predominantly in postmenopausal women, often following exposure to sudden, unexpected emotional or physical st...

Hemochromatosis (cardiac manifestations)

Cardiac involvement in hemochromatosis typically occurs with primary hemochromatosis, as the organ is usually spared in the secondary form of the disease. For a general discussion, and for links to other system specific manifestations, please refer to the article on hemochromatosis.  Epidemiol...

Prosthetic heart valve

Prosthetic heart valves are common. The four valves of the heart may all be surgically replaced. However, the aortic and mitral valves are the most commonly replaced. Replacements may be tissue or metallic valves, only the latter being visualized on imaging investigations. Sometimes the annulus...

Eosinophilic endocarditis

Eosinophilic endocarditis, also known as Loeffler endocarditis, is one of the cardiac manifestations of idiopathic hypereosinophilic syndrome. It also considered a form of cardiomyopathy. Epidemiology There is limited information on the incidence of eosinophilic endocarditis. the majority of ...
Article

Left ventricular outflow tract view (fetal echocardiogram)

The left ventricular outflow tract (LVOT) view (or five chamber view) is one of the standard views in a fetal echocardiogram. It is a long axis view of the heart, highlighting the path from the left ventricle into the ascending aorta (left ventricle outflow tract). In this view the right ventr...
Article

Right ventricular outflow tract view (fetal echocardiogram)

The right ventricular outflow tract (RVOT) view (or three vessel view/3VV) is one of the standard views in a fetal echocardiogram. It is a long axis view of the heart, highlighting the path from the right ventricle into the pulmonary trunk (right ventricular outflow tract). In this view, the r...
Article

Congestive cardiac failure

Congestive cardiac failure (CCF), also known as congestive heart failure (CHF) or simply heart failure, refers to the clinical syndrome caused by inherited or acquired abnormalities of heart structure and function, causing a constellation of symptoms and signs that lead to decreased quality and ...
Article

Left atrial appendage

The left atrial appendage (LAA) (also known as left auricle) is a pouch-like projection from the main body of the left atrium, which lies in the atrioventricular sulcus in close proximity to the left circumflex artery, the left phrenic nerve, and the left pulmonary veins. Gross anatomy Morphol...

Focus‐assessed transthoracic echocardiography

FATE (focus‐assessed transthoracic echocardiography) is a goal-directed protocol used in critical care for indications such as hemodynamic instability, shock, and pulseless electrical activity (PEA) arrest 1. The protocol is designed as a series of questions as follows: does the left ventricle...
Article

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, ...
Article

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...
Article

Transthoracic echocardiography views

A standard transthoracic echocardiogram 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 mandatory for a complete echocardiography protocol. The right parasternal...
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...
