Duchenne muscular dystrophy
Duchenne muscular dystrophy (DMD) is a dystrophinopathy and the most common muscular dystrophy.
Epidemiology
Duchenne muscular dystrophy has an incidence of 1 in 3500 to 5000 males 1,2. The condition is extremely rare in females due to its inheritance pattern, as discussed below 1.
Clinical p...

Kugel's artery
An uncommon variant of coronary arterial anatomy, Kugel's artery was originally described as an anastomotic communication between branches of the proximal left circumflex artery with the distal right coronary artery. These coronary trunks often communicate indirectly through atrial anastomotic n...

Myocardium
The myocardium defines the middle layer of the cardiac wall between the endocardium and the pericardium and forms the muscular part of the heart.
Gross anatomy
The myocardium represents the middle layer of the cardiac wall. It is located between the endocardium and the epicardial layer of the ...
Article
Coronary artery disease
Coronary artery disease (CAD) is primarily due to the narrowing of the coronary arteries due to atherosclerosis, which results in myocardial ischemia and is the leading cause of mortality globally.
Diagnosis
The diagnosis of coronary artery disease is based on typical imaging criteria either ...
Article
Gastropericardial fistula
Gastropericardial fistulas are rare abnormal communications between the stomach and the pericardial sac. This is a life-threatening condition that can lead to impaired cardiac function, sepsis and eventually death.
Clinical presentation
Patients with gastropericardial fistula may present with ...
Article
MR tagging
Cardiac MR tagging or myocardial tagging refers to an MRI-based acquisition method designed for the analysis of myocardial deformation.
Technique
The method exploits tissue magnetization as a tissue property. A local magnetic saturation grid of dark-lined tissue markers known as tags are induc...

Article
Cardiac CT
Computed tomography of the heart or cardiac CT is routinely performed to gain knowledge about cardiac or coronary anatomy, to detect or diagnose coronary artery disease (CAD), to evaluate patency of coronary artery bypass grafts or implanted coronary stents or to evaluate volumetry and cardiac f...
Article
Fractional flow reserve
Fractional flow reserve (FFR) is a technique to evaluate the hemodynamic relevance of coronary artery stenoses 1,2. It is defined as "the ratio of maximal flow achievable in the stenotic coronary artery to the maximal flow achievable in the same coronary artery if it was normal" 1.
Fractional f...
Article
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...
Article
Leadless cardiac pacemaker
Leadless cardiac pacemakers are a type of cardiac conduction device. These pacemakers are self-contained right ventricular single-chamber pacemakers that are implanted percutaneously via a femoral approach 1-3. There are currently two leadless cardiac pacemakers on the market: Nanostim™️ (Abbott...

Visual assessment of coronary artery calcification
Overall visual assessment of coronary artery calcification is a simple scoring system for risk assessment of coronary heart disease mortality by an overall "gestalt" of none, mild, moderate or heavy coronary artery calcification (CAC). It is comparable to the Agatston score but has the advantage...

Libman-Sacks endocarditis
Libman-Sacks endocarditis (LSE), also known as verrucous endocarditis, is a form of non-bacterial thrombotic endocarditis characterized by large thrombi vegetations over the endocardial surface. It was considered the predominant form of endocarditis in systemic lupus erythematosus (SLE) until tr...
