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.Achy Breaky HeartInterbeat interval: Interbeat interval is a scientific term used in the study of the mammalian heart.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.Congenital heart defectLudwig G. KempeHeart transplantationEchogenic 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.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.Third-degree atrioventricular blockKennel clubSeptal 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.End-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).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.
