Heart Anatomy What Is Dilated Cardiomyopathy? Dilated cardiomyopathy (DCM) is a condition in which the heart's ability to pump blood is decreased because the heart's main pumping chamber, the left ventricle, is enlarged and weakened. In some cases, it prevents the heart from relaxing and filling with blood as it should.

Enlarged Heart: Symptoms, Causes and So Much More! Get the facts on the causes, risk factors, and symptoms of an enlarged heart (cardiomegaly). An enlarged heart, or cardiomegaly, is the term used to describe a heart that has a thickened wall or dilated chambers. Having a heart that is enlarged is not a disease but a symptom of an underlying medical condition.

Esophageal dilatation Esophageal dilatation is a therapeutic endoscopic procedure that enlarges the lumen of the esophagus. Pneumatic dilatation or balloon dilatation is also typically done at the time of endoscopy or fluoroscopy. 2  A balloon is inserted in the deflated form into the area of narrowing. 3  It is then inflated with air to a certain pressure that is pre-set for a given circumference.

Hydrocephalus Acute dilatation of the ventricular system is more likely to manifest with the nonspecific signs and symptoms of increased intracranial pressure. By contrast chronic dilatation (especially in the elderly population) may have a more insidious onset presenting, for instance, with Hakim's triad (Adams triad).

- Acute myocardial infarction is the medical name for a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.

Genetic Testing Dilated Cardiomyopathy: A disease of the myocardium (heart muscle) that causes the heart cavity to become stretched and enlarged, and the pumping capacity of the heart is reduced. Dilatation: The increase in size of a blood vessel.

- Dilated cardiomyopathy (DCM) is a condition in which the heart becomes enlarged and cannot pump blood efficiently. The decreased heart function can affect the lungs, liver, and other body systems. DCM is one of the cardiomyopathies, a group of diseases that affect primarily the heart muscle. Different cardiomyopathies have different causes and affect the heart in different ways. In DCM a portion of the myocardium is dilated, often without any obvious cause. Left or right ventricular systolic pump function of the heart is impaired, leading to progressive heart enlargement via ventricular hypertrophy and ventricular dilation, a process called ventricular remodeling.

Practice Essentials Background. Dilated cardiomyopathy is a progressive disease of heart muscle that is characterized by ventricular chamber enlargement and contractile dysfunction with normal left ventricular (LV) wall thickness. The right ventricle may also be dilated and dysfunctional.

cardiac tamponade Acute cardiac tamponade is a sudden accumulation of fluid in the pericardial sac leading to an increase in the intrapericardial pressure. It is a medical emergency whose outcome depends on the speed of diagnosis and treatment as well as the underlying cause.ardiac tamponade compression of the heart due to collection of fluid or blood in the pericardium. It may be either chronic or acute. Chronic cardiac tamponade occurs when fluid slowly enters the pericardial sac, allowing time for the membrane's expansion to accommodate the fluid, which can be as much as 1 liter.

First-degree atrioventricular block First-degree atrioventricular block. First-degree atrioventricular block (AV block), or PR prolongation, is a disease of the electrical conduction system of the heart in which the PR interval is lengthened beyond 0.20 seconds. In first-degree AV block, the impulse conducting from atria to ventricles through the atrioventricular node (AV node) is delayed and travels slower than normal.

Symptoms of Dilated Cardiomyopathy in Dogs Dilated cardiomyopathy in dogs is a condition which causes enlargement of the chambers of the heart. Dilated cardiomyopathy, or DCM, is very common, and is one of the primary causes of congestive heart failure in dogs. Here's what you should know about DCM.

- An uncorrected PDA may lead to congestive heart failure with increasing age. The ductus arteriosus is a fetal blood vessel that closes soon after birth. In a PDA, the vessel does not close and remains patent (open), resulting in irregular transmission of blood between the aorta and the pulmonary artery.rom Wikipedia, the free encyclopedia. Patent ductus arteriosus (PDA) is a congenital heart defect wherein the ductus arteriosus fails to close after birth. Early symptoms are uncommon, but in the first year of life include increased work of breathing and poor weight gain.

Acute blockage Doubt: Complete acute blockage of a coronary artery is found in only about 50% of heart attacks. Acute thrombosis, a blood clot that blocks an artery, can therefore only be the cause of every second heart attack. This, of course, limits the significance of the classical approach. Doubt: The greater the size of the heart attack, the more frequently thrombosis is found.

Pulmonary heart disease Pulmonary heart disease, also known as cor pulmonale is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance or high blood pressure in the lungs. Chronic pulmonary heart disease usually results in right ventricular hypertrophy, whereas acute pulmonary heart disease usually results in dilatation. Hypertrophy is an adaptive response to a long-term increase in pressure. Individual muscle cells grow larger and change to drive the increased co

Acute coronary syndrome Acute coronary syndrome. Acute coronary syndrome (ACS) is a syndrome (set of signs and symptoms) due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. The most common symptom is chest pain, often radiating to the left shoulder or angle of the jaw, crushing, central and associated with nausea and sweating.

Enlarged heart Certain conditions may cause the heart muscle to thicken or one of the chambers of the heart to dilate, making the heart larger. Depending on the condition, an enlarged heart may be temporary or permanent. An enlarged heart may be treatable by correcting the cause. Treatment for an enlarged heart can include medications, medical procedures or surgery.
