Leaking valves of the heart are referred to as having insufficiency or regurgitation. The most common valves to be affected are the aortic and mitral valves. Leaking valves are caused by several conditions, including myxomatous degeneration,...
Your heart consists of four chambers. Two upper atrium and two lower ventricles. Blood returning to the heart after delivering oxygen to the body enters the right atrium. It is then pushed through the left ventricle and into the lungs to be...
The valves in the heart are located between the four chambers and keep the blood flowing in the right direction. These valves can be damaged from heart disease, congenital defect, injury or from infection. These types of damage can lead to...
The heart is made up of four chambers: the right and left atria and the right and left ventricles. Blood enters the heart in the right atrium and travels to the right ventricle, then to the lungs (via the pulmonary artery). Blood re-enters the...
Removing a bike tire to make a repair or replace the tube is something all bike enthusiasts should know how to do. Long-distance or competitive bikers need this skill to make fast tire replacements on the road. A casual biker benefits by saving...
The tricuspid valve sits between the right atrium and the right ventricle. Blood returning to the lungs for oxygenation must traverse the tricuspid valve on its way to the pulmonary artery. The right side of the heart is a low pressure system....
Heart conditions affect children, adolescents, young adults and seniors. Congenital heart defects may show up at birth, or they may manifest later in life. Heart disease is any condition that affects the normal function of the heart's rhythm and...
Your heart has four chambers: two upper chambers called the right and left atrium, and two bottom chambers called the right and left ventricles. Between these chambers are valves that help your blood flow in the right direction. Your tricuspid...
The left atrium is the chamber of the heart that receives oxygenated blood from the lungs. The heart pumps blood from the left atrium, through the mitral valve, into the left ventricle and out to the body. Any condition that increases pressure in...
Basketballs go through plenty of wear-and-tear during games and practices, not to mention just shooting hoops in the driveway. As such, it should come as no surprise when your ball begins to leak. If you enjoy fixing things yourself, can't afford...
A heart murmur is a common medical condition. It is often found incidentally during a routine physical exam. A murmur is the sound of blood flowing across heart valves. It can be due to valves that are narrowed or leaky or can be due to increased...
Bicycle inner tubes have two major types of valves: Presta and Schrader. A third, rarer type of valve is the Woods or Dunlop style. Presta, Schrader and Woods valves are each most common on particular types of bikes, but they function largely the...
Heart valve replacement surgeries are used to treat patients with torn, obstructed or leaking valves that cannot be patched or repaired. According to the Agency for Healthcare Research and Quality, research shows that more than one-third of those...

The aortic valve is the one-way outlet between the lower left heart chamber and the aorta, the large artery that carries oxygenated blood to the body. Malformations, infections and other disease processes can cause obstruction or leaking of the...
Scuba diving can offer a thrilling look at some of the world's most beautiful underwater plants and animals, but a certain amount of skills and knowledge are required to stay safe in a hobby that can put its participants in dangerous situations....
Scuba tanks, also called scuba cylinders, hold oxygen and are worn on the backs of scuba divers. Tanks are made of either aluminum or steel, and both have advantages and disadvantages. Aluminum tanks tend to be less expensive than their steel...
Sodium chloride, or table salt, is the major source for all of the sodium that the average American consumes. While most foods contain some natural sodium, the salt that is added to commercially prepared foods causes most people to consume more...
Blood normally passes through the aortic valve to the aorta and out of the heart. Problems with the valve can obstruct blood flow or cause blood to leak from the valve as it closes. When defects in the aortic valve cannot be repaired, doctors may...
Bicycle tires are more prone to flats than other types of tires. They are abused, stressed, at times punctured and patched, and are under a high amount of pressure. A flat at the wrong time may be inconvenient, as well as dangerous. Routine...
The contents of CO2 tanks can be dangerous, especially when they make contact with skin. All CO2 tanks and cartridges come with warnings about taking necessary measures to prevent an accident.
The simplest, most accessible method to notice the movement of blood through the heart is using your ears. Physicians use a stethoscope to amplify the "lub-dub" sounds of heart valves, which open and close to facilitate blood flow in the correct...
