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...

Tetralogy of Fallot

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart condition with many cases presenting after the newborn period. It has been classically characterized by the combination of ventricular septal defect (VSD), right ventricular outflow tract obstruction (RVOTO), overriding aorta...

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...


Pericarditis is defined as inflammation of the pericardium. It is normally found in association with cardiac, thoracic or wider systemic pathology and it is unusual to manifest on its own. Epidemiology Associations camptodactyly arthropathy coxa vara pericarditis syndrome Clinical presentati...

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...

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...

Intracardiac thrombus

Intracardiac thrombi are seen in a variety of clinical settings and can result in severe morbidity or even death from embolic events. They can occur following myocardial infarction with ventricular thrombus formation, or with atrial fibrillation and mitral stenosis where atrial thrombi predomina...

Right atrial enlargement

Right atrial enlargement is less common, and harder to delineate on chest radiograph, than left atrial enlargement. Pathology Causes Enlargement of the right atrium can result from a number of conditions, including: raised right ventricular pressures pulmonary arterial hypertension cor pul...

Four chamber cardiac view (fetal)

The four chamber cardiac view is an important and routinely performed view in both fetal echocardiography as well as on a standard second trimester anatomy scan. Detectable pathology The four chamber view can only detect some of the congenital cardiac anomalies (~64% according to one study 2) ...

Bicuspid aortic valve

Bicuspid aortic valve (BAV) refers to a spectrum of deformed aortic valves with two functional leaflets or cusps which are often unequal in size. They are most often congenital while an acquired bicuspid valve occurs when there is fibrous fusion between the right and left cusps of a pre-existin...

Left ventricular assist device (Doppler ultrasound)

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 slow...

Speckle tracking echocardiography

Speckle tracking echocardiography describes the semi-automated analysis of grey scale (B-mode) echocardiographic studies in which the spatial translocation of derived functional units (speckles) allows quantitative analysis of myocardial function. Speckle tracking constitutes a subset of deform...

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...

Takotsubo cardiomyopathy

Takotsubo cardiomyopathy (TC) (a.k.a. apical ballooning syndrome) is a condition characterized by transient regional abnormal cardiac wall motion, not confined to a single coronary arterial territory. It has been described predominantly in postmenopausal women, often following exposure to sudden...

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...

Tricuspid valve stenosis

Tricuspid valve stenosis is a valvulopathy that describes narrowing of the opening of the tricuspid valve between the right ventricle and the right atrium. Epidemiology MS is seen more commonly in women and in countries, generally developing nations, where rheumatic fever is common 1,2. Clini...

Crista terminalis

The crista terminalis is a smooth muscular ridge in the superior aspect of the right atrium, formed following resorption of the right valve of the sinus venosus. It represents the junction between the sinus venarum, the "smooth" portion of the right atrium derived from the embryologic sinus veno...

Peripartum/postpartum cardiomyopathy

Peripartum/postpartum cardiomyopathy is a dilated cardiomyopathy that may occur in the last trimester of pregnancy through the first several months postpartum. Epidemiology The estimated incidence in the United States ranges from one in 900 to one in 4000 live births, with an increased inciden...
