Transesophageal echocardiogramVena contracta: frame|right|Vena contractaBlueshift: A blueshift is any decrease in wavelength, with a corresponding increase in frequency, of an electromagnetic wave; the opposite effect is referred to as redshift. In visible light, this shifts the color from the red end of the spectrum to the blue end.Superficial velocity: Superficial velocity (or superficial flow velocity), in engineering of multiphase flows and flows in porous media, is a hypothetical (artificial) flow velocity calculated as if the given phase or fluid were the only one flowing or present in a given cross sectional area. Other phases, particles, the skeleton of the porous medium, etc.DobutamineMitral valve replacementEnd-diastolic volume: In cardiovascular physiology, end-diastolic volume (EDV) is the volume of blood in the right and/or left ventricle at end load or filling in (diastole) or the amount of blood in the ventricles just before systole. Because greater EDVs cause greater distention of the ventricle, 'EDV is often used synonymously with preload, which refers to the length of the sarcomeres in cardiac muscle prior to contraction (systole).DiastoleAssay sensitivity: Assay sensitivity is a property of a clinical trial defined as the ability of a trial to distinguish an effective treatment from a less effective or ineffective intervention. Without assay sensitivity, a trial is not internally valid and is not capable of comparing the efficacy of two interventions.Left atrial enlargement: Left atrial enlargement (LAE) or left atrial dilation refers to enlargement of the left atrium (LA) of the heart, and is a form of cardiomegaly.Atrial septal defectEchogenic intracardiac focus: Echogenic intracardiac focus (EIF) is a small bright spot seen in the baby’s heart on an ultrasound exam. This is thought to represent mineralization, or small deposits of calcium, in the muscle of the heart.Congenital heart defectCoronary perfusion pressure: Coronary perfusion pressure (CPP) refers to the pressure gradient that drives coronary blood pressure, meaning the difference between the diastolic aortic pressure and the right atrial diastolic pressure. It is a term used mainly in research concerning cardiac arrest.Automated ECG interpretation: Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.Schering AGGeneralizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.Aortic valve replacementTreadmill: A treadmill is a device generally for walking or running while staying in the same place. Treadmills were introduced before the development of powered machines, to harness the power of animals or humans to do work, often a type of mill that was operated by a person or animal treading steps of a treadwheel to grind grain.Tricuspid insufficiencyFeasibility Study (The Outer Limits): "Feasibility Study" is an episode of The Outer Limits television show. It was first broadcast on 11 July 1997, during the third season.Inotrope: An inotrope (etymology and pronunciation) is an agent that alters the force or energy of muscular contractions. Negatively inotropic agents weaken the force of muscular contractions.Septal myectomy: Septal myectomy is a cardiac surgery treatment for hypertrophic cardiomyopathy (HCM). The surgery entails removing a portion of the septum that is obstructing the flow of blood from the left ventricle to the aorta.Afterload: Afterload is the pressure in the wall of the left ventricle during ejection. In other words, it is the end load against which the heart contracts to eject blood.Robot-assisted double heart valve replacement: The first robotic-assisted double heart valve replacement was carried out in the Chennai region of India at Chettinad Hospital. Considered a rare form of surgery, this is the first instance of such a procedure using robotic surgery.Booster pump: Booster}}Concentric hypertrophy: Concentric hypertrophy is a hypertrophic growth of a hollow organ without overall enlargement, in which the walls of the organ are thickened and its capacity or volume is diminished.Achy Breaky HeartCommissurotomy: A commissurotomy is a surgical incision of a commissure in the body, as one made in the heart at the edges of the commissure formed by cardiac valves, or one made in the brain to treat certain psychiatric disorders.Management of heart failure: Management of heart failure requires a multimodal approach. It involves a combination of lifestyle modifications, medications, and possibly the use of devices or surgery.Aortic insufficiencyElectrocardiography in myocardial infarctionDipyridamoleHandgrip maneuver: The handgrip maneuver is performed by clenching one's fist forcefully for a sustained time until fatigued. Variations include squeezing an item such as a rolled up washcloth.Coronary ischemia: Coronary ischemia is a medical term for not having enough blood through the coronary arteries. Coronary ischemia is linked to heart disease as well as heart attacks.Systolic heart murmur: 200px|thumb|right|[[Auscultogram from normal and abnormal heart sounds]]Myocardial disarray: Myocardial disarray, also known as myocyte disarray, is a term to describe the loss of the normal parallel alignment of myocytes (the muscle cells of the heart). Instead, the myocytes usually form circles around foci of connective tissue.Intravascular ultrasoundTamponadeVentricular septal defectAbdominal ultrasonographyEthernet flow control: Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The first flow control mechanism, the PAUSE frame, was defined by the IEEE 802.Pulmonary artery banding: Pulmonary Artery Banding (PAB) was introduced by Muller and Danimann in 1951 as a surgical technique to reduce excessive pulmonary blood flow in infants suffering from congenital heart defects.Muller WH, Dammann JF.CardiomyopathyAortic pressure: Central aortic blood pressure (CAP or CASP) is the blood pressure at the root of aorta. Studies have shown the importance of central aortic pressure and its implications in assessing the efficacy of antihypertensive treatment with respect to cardiovascular risk factors.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingPerfluorodecalinPulmonary Hypertension Association: The Pulmonary Hypertension Association (PHA) is a 501(c) organization non-profit support, education, advocacy and awareness association for pulmonary hypertension (PH). It provides information to the public about the illness and acts as a support group for those with the disease, providing medical provider location services and emotional support for those suffering from the illness.Myocytolysis: Myocytolysis refers to a degenerative change (often reversible) that occurs to myocytes upon myocardial strain. This phenomenon tends to occur when neighboring cardiac muscle loses its ability to contract (i.Cardiac function curve: A cardiac function curve is a graph showing the relationship between right atrial pressure (x-axis) and cardiac output (y-axis).Hybrid cardiac surgery: A hybrid cardiac surgical procedure in a narrow sense is defined as a procedure that combines a conventional surgical part (including a skin incision) with an interventional part, using some sort of catheter-based procedure guided by fluoroscopy (or other, e.g.Ventricular aneurysm: Ventricular aneurysms are one of the many complications that may occur after a heart attack (myocardial infarction). They usually arise from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood.Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.Left atrial appendage occlusionPhonocardiogramAtrial myxoma: An atrial myxoma is a benign tumor of the heart, commonly found within the left and right atria on the interatrial septum.Arterial embolism
