Pericardial agenesis
Pericardial agenesis is a rare condition where there is the absence of the pericardium to varying degrees. If it is only a small portion of the pericardium that is absent it is known as a pericardial defect.
Epidemiology
According to a surgical and pathological series, the prevalence (inclusiv...

Tricuspid valve regurgitation
Tricuspid valve regurgitation (TR), also known as tricuspid valve insufficiency or tricuspid valve incompetence (TI), is a valvulopathy that describes leaking of the tricuspid valve (TV) during systole that causes blood to flow in the reverse direction from the right ventricle (RV) into the righ...

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.

Article
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...
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...

Coronary microvascular obstruction
Microvascular obstruction (MVO), also known as no-reflow phenomenon, is an established complication encountered in coronary angioplasty for prolonged acute myocardial infarction.
Pathology

Implantable loop recorder
Implantable loop recorders, also known as insertable cardiac monitors, are small insertable devices that continuously monitor and record cardiac rhythms. They are placed subcutaneously and used for the evaluation of patients with recurrent unexplained episodes of palpitations or syncope.

Congenitally corrected transposition of the great arteries
Congenitally corrected transposition of the great arteries, also known as levo- or L-loop transposition (L-TGA), is a rare cardiovascular anomaly with inversion of the ventricles and great arteries. See the main article on transposition of the great arteries for discussion of the D-loop subtype....
Article
Lambl’s excrescence
Lambl’s excrescences, also known as valvular strands, are small, filiform, fibrous strands located on cardiac valves.
Epidemiology
Thought to be present in 70-80% of adults according to pathological studies, but only ~40% on echocardiograph studies 1. When present, multiple Lambl’s excrescence...
Article
Aortic valve regurgitation
Aortic valve regurgitation, also known as aortic valve insufficiency or aortic valve incompetence, is a valvulopathy that describes leaking of the aortic valve during diastole that causes blood to flow in the reverse direction from the aorta and into the left ventricle.
Epidemiology
Aortic reg...
Article
Leadless cardiac pacemaker
Leadless cardiac pacemakers are a recently introduced 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...

Article
Pulmonary valve stenosis
Pulmonary valve stenosis, or pulmonic valve stenosis, is a valvulopathy that describes the narrowing of the opening of the pulmonary valve between the pulmonary trunk and the right ventricle.
