Heart Valve Dysplasia
Heart valve dysplasia is a congenital heart defect which affects the aortic, pulmonary, mitral, and tricuspid heart valves. Dysplasia of the mitral and tricuspid valves can cause leakage of blood or stenosis. Dysplasia of the mitral and tricuspid valves - also known as the atrioventricular (AV) valves - can appear as thickened, shortened, or notched valves. The chordae tendinae can be fused or thickened. The papillary muscles can be enlarged or atrophied. The cause is unknown, but genetics play a large role. Dogs and cats with tricuspid valve dysplasia often also have an open foramen ovale, an atrial septal defect, or inflammation of the right atrial epicardium. In dogs, tricuspid valve dysplasia can be similar to Ebstein's anomaly in humans. Mitral valve stenosis is one of the most common congenital heart defects in cats. In dogs, it is most commonly found in Great Danes, German Shepherd Dogs, Bull Terriers, Golden Retrievers, Newfoundlands, and Mastiffs. Tricuspid valve ...

Heart
The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while most reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newfoundland (dog)
The Newfoundland is a large working dog. They can be black, brown, or black and white. However, in the Dominion of Newfoundland, before it became part of the confederation of Canada, only black and Landseer (white-and-black) coloured dogs were considered to be proper members of the breed. They were originally bred and used as working dogs for fishermen in Newfoundland. Newfoundlands are known for their giant size, intelligence, tremendous strength, calm disposition, love of children and loyalty. They excel at water rescue/lifesaving because of their muscular build, thick double coat, webbed paws, and swimming abilities. Description Appearance Newfoundlands ('Newfs' or 'Newfies') have webbed paws and a water-resistant coat.Newfoundland Breed Standard |

Prognosis
Prognosis (Greek: πρόγνωσις "fore-knowing, foreseeing") is a medical term for predicting the likely or expected development of a disease, including whether the signs and symptoms will improve or worsen (and how quickly) or remain stable over time; expectations of quality of life, such as the ability to carry out daily activities; the potential for complications and associated health issues; and the likelihood of survival (including life expectancy). A prognosis is made on the basis of the normal course of the diagnosed disease, the individual's physical and mental condition, the available treatments, and additional factors. A complete prognosis includes the expected duration, function, and description of the course of the disease, such as progressive decline, intermittent crisis, or sudden, unpredictable crisis. When applied to large statistical populations, prognostic estimates can be very accurate: for example the statement "45% of patients with severe septic shock w ...

Echocardiography
An echocardiography, echocardiogram, cardiac echo or simply an echo, is an ultrasound of the heart. It is a type of medical imaging of the heart, using standard ultrasound or Doppler ultrasound. Echocardiography has become routinely used in the diagnosis, management, and follow-up of patients with any suspected or known heart diseases. It is one of the most widely used diagnostic imaging modalities in cardiology. It can provide a wealth of helpful information, including the size and shape of the heart (internal chamber size quantification), pumping capacity, location and extent of any tissue damage, and assessment of valves. An echocardiogram can also give physicians other estimates of heart function, such as a calculation of the cardiac output, ejection fraction, and diastolic function (how well the heart relaxes). Echocardiography is an important tool in assessing wall motion abnormality in patients with suspected cardiac disease. It is a tool which helps in reaching an ear ...

Heart Failure
Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome, a group of signs and symptoms caused by an impairment of the heart's blood pumping function. Symptoms typically include shortness of breath, excessive fatigue, and leg swelling. The shortness of breath may occur with exertion or while lying down, and may wake people up during the night. Chest pain, including angina, is not usually caused by heart failure, but may occur if the heart failure was caused by a heart attack. The severity of the heart failure is measured by the severity of symptoms during exercise. Other conditions that may have symptoms similar to heart failure include obesity, kidney failure, liver disease, anemia, and thyroid disease. Common causes of heart failure include coronary artery disease, heart attack, high blood pressure, atrial fibrillation, valvular heart disease, excessive alcohol consumption, infection, and cardiomyopathy. These cause heart failure by altering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Arrhythmia
Arrhythmias, also known as cardiac arrhythmias, heart arrhythmias, or dysrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. Some types of arrhythmias have no symptoms. Symptoms, when present, may include palpitations or feeling a pause between heartbeats. In more serious cases, there may be lightheadedness, passing out, shortness of breath or chest pain. While most cases of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in sudden death. Arrhythmias are often categorized into four groups: extra beats, supraventricular tachycardias, ventricular arrhythmias and bradyarrhythmias. Extra beats include premature atrial contractions, premature ventricular contractions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papillon (dog)
The Papillon (, French for 'butterfly eared), also called the Continental Toy Spaniel, is a breed of dog, of the spaniel type. One of the oldest of the toy spaniels, it derives its name from its characteristic butterfly-like look of the long and fringed hair on the ears. A Papillon with dropped ears is called a Phalene. Appearance and behavior Papillons are very intelligent and self-assured dogs that have a very easy time learning new tricks. These dogs can be sociable with children and strangers, but are generally reserved around new people. They can also be socialized to get along well with other pets, but care should be taken with rambunctious pets or cats with claws, as they may injure them. If not properly socialized, Papillons can be distrustful and exhibit aggressive tendencies toward other dogs and people. Papillons may also be very playful and affectionate. Widely known as great companion dogs, they have the spirit and energy to keep up with active families, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrenean Mountain Dog
The Pyrenean Mountain Dog (french: Chien de Montagne des Pyrénées) is a breed of livestock guardian dog from France, where it is commonly called the Patou. The breed comes from the French side of the Pyrenees Mountains that separate France and Spain. It is recognised as a separate breed from the closely related Pyrenean Mastiff, which is from the Spanish side of the mountains. The breed is widely used throughout France as a livestock guardian, particularly in the French Alps and Pyrenees, protecting flocks from predation by wolves and bears. The breed is known as the Great Pyrenees in the United States, where it is also used to protect flocks from various predators. History The Pyrenean Mountain Dog is a traditional breed of the Pyrenees. In France it is usually called the 'Patou'. It is sometimes claimed that its forebears – and those of the Pyrenean Mastiff – were white livestock guardian dogs brought to the area from Asia in Roman times, and thus that it is related ...

Weimaraner
The Weimaraner ( ) is a large dog that was originally bred as a hunting dog in the early 19th century. Early Weimaraners were used by royalty for hunting large game such as boar, bear and deer. As the popularity of large game hunting began to decline, Weimaraners were used for hunting smaller animals like fowl, rabbits and foxes. The Weimaraner is an all-purpose gun dog. The name comes from the Grand Duke of Saxe-Weimar-Eisenach, Karl August, whose court, located in the city of Weimar (now in the state of Thuringia in modern-day Germany), enjoyed hunting. The Weimaraner possesses traits such as speed, stamina, great sense of smell, great eyes, courage, and intelligence. The breed is sometimes referred to as the "grey ghost" of the dog world originating from its ghostly coat and eye color along with its stealthy hunting style. History The Weimaraner was kept in the Weimar court in the 19th century and carried a good deal of Leithound ancestry. Two theories propose that they d ...

Old English Sheepdog
The Old English Sheepdog is a large breed of dog that emerged in England from early types of herding dog. Obsolete names for the breed include Shepherd's Dog and . The nickname ''Bob-tail'' (or ''Bobtail'') originates from how dogs of the breed traditionally had their tails docked. Old English Sheepdogs can grow very long coats with fur covering the face and eyes and do not shed unless brushed. Appearance The Old English Sheepdog is a large dog, immediately recognizable by its long, thick, shaggy grey and white coat, with fur covering their face and eyes. The ears lie flat to the head. Historically, the breed's tail was commonly docked (resulting in a panda bear–like rear end), but tailed Old English sheepdogs are now common, as many countries have outlawed cosmetic docking. When the dog has a tail, it has long fur (feathering), is low set, and normally hangs down. The Old English Sheepdog stands lower at the shoulder than at the loin, and walks with a "bear-like roll from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
