Aortomitral continuity
The aortomitral continuity (also known as the aortomitral curtain, aorticomitral junction, intervalvular fibrous body) is a fibrous sheet located between the noncoronary and left coronary leaflets of the aortic valve and anterior leaflet of the mitral valve. It is attached by the left and right ...

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.

Left atrium
The left atrium (LA) (plural: atria) is one of the four chambers of the heart. It receives oxygenated blood from the pulmonary circulation that is then delivered to the left ventricle and then into the systemic circulation.
Gross anatomy
The left atrium is grossly cuboidal. It is the most supe...

Sarcoidosis (cardiac manifestations)
Cardiac involvement of sarcoidosis is a manifestation of sarcoidosis which is often asymptomatic, although can be associated with high mortality 8. Autopsy studies show prevalence of ~25% cardiac involvement, yet only 5-10% are found symptomatic 1,2.
Sarcoidosis is a multisystem disorder chara...
Article
Regurgitant volume and regurgitant fraction
The regurgitant volume refers to the volume of blood flowing backwards or in the reverse direction through the valvular plane within a beat or cardiac cycle.
The regurgitant fraction is referred to as the backflowing blood volume divided by the forward flow volume and is expressed in percent [%...

Miminally invasive direct coronary artery bypass
Minimally invasive direct coronary artery bypass (MIDCAB) is a novel method for bypassing diseased coronary arteries that can replace open coronary artery bypass grafts (CABG) in certain situations, most commonly when bypassing the left anterior descending artery (LAD) with a left internal thora...
Article
Cardiomyopathy
Cardiomyopathy is defined as a "disease of the myocardium with associated cardiac dysfunction" 1. It has been classified according to several systems:
1995 WHO/ISFC cardiomyopathy classification system
Elliott et al. classification system: published by the European Society of Cardiology Workin...
Article
Approach to shock (echocardiography)
An organized approach to shock is critical in the management of these often very sick patients. Shock - of any form - manifests as inadequate tissue perfusion, the end-point of which is multisystem organ failure and death.
Echocardiography at the point-of-care is fast, non-invasive, and often p...
Article
Chagas disease
Chagas disease, also known as American trypanosomiasis (plural: trypanosomiases), is a tropical parasitic infection with a wide spectrum of clinical manifestations since it can virtually affect any organ, but there are characteristic radiological features.
Epidemiology
Chagas disease is endemi...
Article
Cervical aortic arch
Cervical aortic arches are a rare aortic arch anomaly characterized by an elongated, high-lying aortic arch extending at or above the level of the medial ends of the clavicles.
Clinical presentation
Patients with cervical aortic arch are usually asymptomatic. Symptomatic patients may present w...
Article
Pulmonary valve regurgitation
Pulmonary valve regurgitation, also known as pulmonary valve insufficiency or pulmonary valve incompetence, is a valvulopathy that describes leaking of the pulmonary valve diastole that causes blood to flow in the reverse direction from the pulmonary trunk and into the right ventricle.
Epidemio...
Article
Right-to-left shunt (mnemonic)
A useful mnemonic to remember the differential diagnoses associated with right-to-left cardiovascular shunts is:
1-5
Mnemonic
1: a combination vessel; truncus arteriosus
2: number of arteries involved; transposition of the great arteries
3: "tri-" means 3, the number of leaflets involved; t...
Article
Surgical hemostatic material
Surgical hemostatic material is used to control bleeding intraoperatively and is hence frequently intentionally left in the operative bed, not to be confused with a gossypiboma which is caused by foreign material left behind in error. Its use has increased with the advent of minimally invasive s...
Article
Right heart strain
Right heart strain (or more precisely right ventricular strain) is a term given to denote the presence of right ventricular dysfunction usually in the absence of an underlying cardiomyopathy. It can manifest as an acute right heart syndrome.
Pathology
Right heart strain can often occur as a re...
Article
Cardiovascular shunts
Cardiovascular (cardiac) shunts are abnormal connections between the pulmonary and systemic circulations. Most commonly they are the result of congenital heart disease.
Pathology
Blood can either be shunted from the systemic circulation to pulmonary circulation (i.e. 'left-to-right shunt') or ...
Article
Left atrial appendage
The left atrial appendage, 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
Morphological...

Left dominant arrhythmogenic cardiomyopathy
Left dominant arrhythmogenic cardiomyopathy is a variant of arrhythmogenic right ventricular cardiomyopathy that predominantly affects the left ventricle of the heart. It may also be known as arrhythmogenic left ventricular cardiomyopathy 4.
Clinical presentation
The main clinical diagnostic f...
Article
Hibernating myocardium
Hibernating myocardium is myocardial tissue that has reduced contractility due to poor perfusion but remains viable. In ischemic heart disease, evaluating myocardial viability is important because hibernating myocardium can recover function after revascularization.
Pathology
Hibernating myoca...

Mitral valve leaflet calcification
Mitral valve leaflet calcification or mitral leaflet calcification refers to the deposition of calcium on the mitral valvular leaflets as opposed to mitral annular calcification in the mitral annulus. It has been associated with mitral stenosis 1,2.
Epidemiology
Mitral leaflet calcification h...
