Congestive cardiac failure
Congestive cardiac failure (CCF), also known as congestive heart failure (CHF) or simply heart failure, refers to the clinical syndrome caused by inherited or acquired abnormalities of heart structure and function, causing a constellation of symptoms and signs that lead to decreased quality and ...
Article
Glenn shunt
The Glenn shunt, also known as Glenn procedure, is a palliative surgical procedure for a variety of cyanotic congenital heart diseases.
Rationale
In this procedure, the systemic venous return is re-directed to the pulmonary circulation, bypassing the right heart 1-3.
It can be used in a varie...
Article
Rastelli procedure
The Rastelli procedure is a surgical procedure to correct certain combinations of cardiovascular defects in patients with cyanotic congenital heart disease.
Rationale
The operation is based on a redirection of ventricular outflows using an intracardiac baffle that tunnels the left ventricle to...
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
Total repair of tetralogy of Fallot
Total repair of tetralogy of Fallot is a corrective surgical procedure that involves closure of the ventricular septal defect (VSD) and relief of right ventricular outflow tract (RVOT) obstruction.
Procedure
Most patients with tetralogy of Fallot (TOF) undergo elective surgical repair between ...
Article
Unifocalisation procedure
A unifocalisation procedure is a corrective surgical technique used in patients with complete pulmonary artery atresia with major aortopulmonary collateral arteries (MAPCAs). In this technique, the collateral vessels supplying blood from the aorta directly to the lungs are brought into continuit...
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...
Article
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
The phenomenon results from obstruction of the myocardial microcirculation, which is composed of vessel...
Article
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
Syphilitic aortitis
Syphilitic aortitis is a form of aortitis which occurs due to syphilis. It usually occurs in tertiary syphilis often 10-30 years after initial infection.
Complications
progression into a luetic aneurysm
aortic valvular insufficiency
coronary ostial involvement with coronary ostial stenosis
...
Article
Aorto-ventricular tunnel
Aorto-ventricular tunnel (AVT) is an extremely rare form of congenital heart disease, representing an anomalous extracardiac communication between the ascending aorta and the left or right ventricles.
Terminology
In most cases the anomalous communication is between the aorta and the left ventr...
Article
Atrial septal occlusion device
Atrial septal occlusion devices are implantable cardiac devices used in patients with certain types of atrial septal defects or patent foramen ovale 4.
They are used in cases of atrial septal defects with right atrial or ventricle enlargement, to prevent paradoxical embolism, left-to-right shun...
Article
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
Transesophageal echocardiography
A standard transesophageal echocardiography (TOE, or TEE in US English) is a type of echocardiography using an endoscopic transducer, which is advanced into the thoracic esophagus, offering generally superior visualization of the great vessels and posterior cardiac structures than the standard t...
Article
Brugada syndrome
A cardiac "channelopathy" resulting from mutations in genes coding for cardiac sodium (Na+) channels, the Brugada syndrome is a common cardiac cause of sudden death in patients with structurally normal hearts.
Epidemiology
Age of diagnosis ranges from 2 days to 84 years old. It is estimated to...
Article
De Winter pattern (electrocardiogram)
An electrocardiographic finding suggestive of impending myocardial infarction, the de Winter's pattern (or "de Winter's T-waves") describes an abnormality thought to be indicative of acute occlusion of the proximal left anterior descending coronary artery (LAD) 2. Timely recognition of this patt...
Article
Wolff-Parkinson-White syndrome
The Wolff-Parkinson-White syndrome describes paroxysmal tachydysrhythmias in the presence of a specific accessory pathway which allows direct electrical connection between the atria and ventricles, which usually exclusively occurs via the atrioventricular (AV) node. The accessory pathway is usua...
Article
Left bundle branch block
A form of interventricular conduction defect most often diagnosed on the electrocardiogram, the presence of a left bundle branch block (LBBB) disrupts the normal sequence of ventricular depolarization.
Epidemiology
Aberrant conduction in the left bundle branch producing a conduction block is ...
Article
Single chamber cardiac pacers
Single chamber cardiac pacemakers are cardiac conduction devices with one lead terminating in (most commonly) the right ventricular apex or the right atrium.
Components
Includes one of the following:
lead in the right atrium
lead in the right ventricle
Function
Single chamber atrial pac...
