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...

Right atrium
The right atrium (RA) (plural: atria) is one of the four chambers of the human heart, and is the first chamber to receive deoxygenated blood returning from the body, via the two venae cavae. It plays an important role in originating and regulating the conduction of the heart.

Article
Great cardiac vein
The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.
Gross anatomy
It begins on the anterior surface of th...
Article
LCx and LAD arising separately from the left coronary sinus
One of the anatomical variants of coronary artery origin comprises the left circumflex coronary artery (LCx) and left anterior descending coronary artery (LAD) arising separately from the left coronary sinus. Hence there is no common left main coronary artery (LCA/LMCA).
It considered the commo...

Right ventricle
The right ventricle (RV) is the most anterior of the four heart chambers. It receives deoxygenated blood from the right atrium (RA) and pumps it into the pulmonary circulation. During diastole, blood enters the right ventricle through the atrioventricular orifice through an open tricuspid valve ...
Article
Coumadin ridge
A coumadin ridge, also called warfarin ridge or left lateral ridge, is a band-like embryological remnant in the left atrium between the left superior pulmonary vein and the left atrial appendage. It is considered an anatomical variant.
The ridge is formed by the coalition of the left superior ...
Article
Biventricular cardiac pacemaker
Biventricular cardiac pacemakers are surgically implanted cardiac conduction devices with one lead in each ventricle (and often one in the right atrium) used for cardiac resynchronization therapy.
Components
lead in the right atrium
lead in the right ventricle
lead in the coronary sinus t...

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...
Article
Athlete heart syndrome
Athlete heart syndrome refers to adaptations in both cardiac structure and function seen in people engaged in high-performance and endurance physical exercise.
Epidemiology
The prevalence of the condition has increased due to the increased popularity of recreational exercise, approx 3.6/100,00...
Article
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
Chiari network
A Chiari network refers to a filamentous, weblike structure in the right atrium that results from incomplete resorption of the embryonic sinus venosus. It is an uncommon anatomical variant.
Epidemiology
Prevalence estimates for the general population vary widely, ranging from 2%-10% of randoml...

Left ventricular hypertrophy
Left ventricular hypertrophy (LVH) is present when the left ventricular mass is increased. It is a common condition, typically due to systemic hypertension, and it increases with age, obesity and severity of hypertension.
Epidemiology
Studies have demonstrated a prevalence on echocardiography ...
Article
Late gadolinium enhancement
Late gadolinium enhancement is a technique used in cardiac MRI for cardiac tissue characterization, in particular, the assessment of myocardial scar formation and regional myocardial fibrosis 1-5.
Terminology
Late gadolinium enhancement is also known under the terms ‘late enhancement’ or ‘dela...
Article
Myocardial scar tissue
Myocardial scar tissue or myocardial scar is referred to as the final result and pathological correlate of myocardial infarction or myocardial injury and typically develops from the infarcted myocardium.
Terminology
Myocardial scar tissue is the result of replacement fibrosis and is also calle...
Article
Intramyocardial hemorrhage
Intramyocardial hemorrhage is referred to as the extravasation of erythrocytes and/or blood products into the myocardium.
Epidemiology
Intramyocardial hemorrhage occurs in 35-50% of the patients with successful coronary revascularization of ST-elevation myocardial infarction 1-4.
