Myocardial area at risk
The myocardial area at risk (AAR) is defined by the ischemic proportion of the myocardium after coronary occlusion and reflects the potential size of the myocardial infarction 1-9.
Usage
The assessment of the myocardial area at risk is an important measure in the evaluation of the potentially ...

Mitral aortic intervalvular fibrosa
The mitral-aortic intervalvular fibrosa (MAIVF) refers to a thin, fibrous, membranous avascular region located between the anterior leaflet of the mitral valve (left atrioventricular orifice) and non-coronary cusp of the aortic valve in the heart.
It extends from the right fibrous trigone to th...
Article
Ventricular interdependence
Ventricular interdependence (or ventricular coupling) is a phenomenon whereby the function of one ventricle is altered by changes in the filling of the other ventricle. This leads to a volume increase of one ventricle associated with a decreased volume in the opposite ventricle 1.
This conditio...
Article
Pseudoaneurysm of the mitral aortic intervalvular fibrosa
Pseudoaneurysm of the mitral aortic intervalvular fibrosa (p-MAIVF) refers to a pseudoaneurysm in the region of the avascular fibrous tissue between the mitral and aortic valves (i.e. the mitral-aortic intervalvular fibrosa (MAIVF)).
Pathology
Etiology
They may rarely occur as a result of inf...
Article
Chronic thromboembolic pulmonary hypertension
Chronic thromboembolic pulmonary hypertension (CTEPH) is a distinct subgroup of pulmonary hypertension that most frequently develops following massive or repeated pulmonary embolism.
Terminology
The term CTEPH should be used for patients with chronic thromboembolic disease and pulmonary hypert...

MRI in patients with pacemaker systems
MRI in patients with cardiac implantable electronic devices (CIED) has increasingly become a requirement in radiological departments 1-8. Especially in the setting of patients with MR conditional pacemaker systems, where all the manufacturer's instructions are followed and a standardized institu...

Pulseless electrical activity
The diagnosis of pulseless electrical activity (PEA), also known as electromechanical dissociation (EMD), refers to the presence during cardiac arrest of electrical activity of the heart, in the absence of a ventricular tachyarrhythmia, but no measurable cardiac output 1,2. PEA is one of the non...
Article
Coronary artery bypass graft
A coronary artery bypass graft (CABG or CAG) is placed during a surgical procedure to increase blood flow to the myocardium due to coronary stenoses, usually caused by coronary artery disease. Arteries or veins can be grafted during this procedure.
Long term outcome of coronary artery bypass gr...
Article
Cardiac strain imaging
Strain imaging is a cardiac imaging technique that detects ventricular deformation patterns and functional abnormalities before they become obvious as regional wall motion abnormalities on conventional cine imaging or echo. It has become more popular lately due to several technological improveme...
Article
Chronic coronary syndrome
Chronic coronary syndrome (CCS) is a term that defines coronary artery disease as a chronic progressive course that can be altered, stabilized or improved by lifestyle modifications, pharmacotherapy and coronary revascularization. It has been introduced to replace the previous term ‘stable coron...
Article
Paravalvular leak
A paravalvular leak, paravalvular leakage or paravalvular regurgitation are an abnormal flow between the valvular annulus and the prosthetic heart valve and is a common complication after valvular replacement surgery due to inadequate sealing.
Epidemiology
Paravaluvar leaks are common, with an...
Article
Atrial fibrillation
A common consequence of atrial enlargement and/or inflammation, atrial fibrillation is a dysrhythmia originating from the atria, typically recognized on the electrocardiogram. It most commonly presents as a tachyarrhythmia, with ventricular rates between 120-130 beats per minute. Defining electr...
