The right ventricle pumps blood through the pulmonary valve into the pulmonary artery. Once blood passes into the pulmonary artery the pulmonary valve closes to prevent backflow of blood into the right ventricle.The right ventricle fills and contracts to pump blood to the lungs.This oxygen-poor blood then passes through the tricuspid valve into the right ventricle. The tricuspid valve closes after the blood passes through to prevent it from flowing back into the right atrium.The two largest veins in the body, the superior and inferior vena cava, bring the oxygen-poor (blue) blood to the heart into the right atrium.The four chambers of the heart are attached to major veins or arteries that either bring blood into or carry blood away from the heart. How blood circulates through the heart and body The aortic valve is located between the left ventricle and the aorta.The mitral valve is between the left atrium and the left ventricle.The pulmonary valve is between the right ventricle and the pulmonary artery.The tricuspid valve is between the right atrium and the right ventricle.There are four valves within the heart. Each valve has flaps that prevent blood from flowing in the wrong direction - opening to allow forward flow of blood and closing to prevent backward flow. Muscular walls, called septa or septum, divide the heart into two sides and keep the two kinds of blood from mixing.On the left side of the heart, the left atrium and left ventricle combine to pump oxygenated blood back through the body.On the right side of the heart, the right atrium and right ventricle work to pump oxygen-poor blood returning from the body back to the lungs to be reoxygenated.The heart is a two-sided pump made up of four chambers: the upper two chambers called atria and the lower two called the ventricles. You will need to stay in the hospital under your blood flow is restored, which can take several days.View this video with a transcript The structure of the heart Your doctor will give you medicine in your artery to break up clots and restore blood flow. Treatments performed in the heart are minimally invasive, but require patients to stay in the hospital for a day or two before returning home. Most patients will go home the day of the procedure for treatments performed outside the heart. Your doctor will use a small tube with a controlled, spinning tip to break up hard plaque and remove your blockage. Patients with significant disease who are unsuitable for surgery can instead be treated using a stenting technique called complex high-risk percutaneous coronary intervention (PCI). Treatments performed in the heart are minimally invasive but require patients to stay in the hospital for a day or two before returning home. Your doctor will insert a small wire mesh known as a stent to help stabilize your artery walls. The decision about whether to use a stent will be made during your angioplasty, depending on the condition of the blocked artery.
Your doctor will identify the blockage then widen the blocked artery using a small balloon attached to a thin tube, improving your blood flow. Minimally Invasive AccessĪngiography can usually be done using an artery in your wrist instead of your femoral artery, which is associated with less bleeding, fewer complications and a quicker recovery.
AngioplastyĪlso called a PCI when performed in the heart, this procedure uses X-ray imaging and a small balloon attached to a thin tube to widen your artery and improve blood flow. Your treatment method will depend on the makeup of your blockage, the size of your blood vessels, the location of the blockage and your health history.
