The Mitral Valve is in between the left atrium and the left ventricle of the heart. Oxygenated blood is pumped from left atrium to the left ventricle through that valve, mitral valve, then to the whole body through the Aorta artery. So problems with this valve may make the blood go back to the atrium during the contraction of the ventricle and this leads to decrease of the pressure of blood and the amount of it to the Aorta. This can affect the whole body.
The human heart has four chambers: right atrium, right ventricle, left atrium, and left ventricle.The right ventricle pumps de-oxygenated blood to the lungs :The right ventricle of the human heart receives de-oxygenated blood from the right atrium via the tricuspid valve, and pumps it into the pulmonary artery,which leads to the lungs , via the pulmonary valve.
I don't think you have grasped the concept... Blood is pumped thru the left ventricle to the tissues, from the tissues to the veins and into the right atrium. The right atrium pumps the blood to the right ventricle, your right ventricle pushes the blood into the pulmonary arteries, this leads to the pulmonary capillaries (in which oxygenation takes place), from there to the pulmonary veins to the left atrium, then the left ventricle....
the answer is in the question. if the pacemaker is replaced the leads are used for it.
All four of the heart's chambers squeeze blood out into the corresponding chamber or artery. The right atrium pumps blood from the body into the right ventricle, and the right ventricle pumps that blood out of an artery that leads to the lungs. The blood then returns to the heart and is pumped by the left atrium to the left ventricle, which pumps the blood to the rest of the body.
Right side * Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. * As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve. * When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts. * As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated. Left side * The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium. * As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. * When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts. * As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.
The wave of contraction in heart is initiated by S.A. Node which leads left auricles to contract. This wave of contraction is received by A.V.Node which contracts right auricle and spreads the wave of contraction to bundle of his and finally to purkinje fibre which contracts the two ventricles simultaneously anterioposteriorly. Therefore sequence of contraction is 1Left Auricle 2 Right auricle 3 ventricle

Depending on the configuration of the pacemaker and the clinical needs of the patient, as many as three leads may be used in a pacing system.
It should be Oscor active fixation leads. It refers to the leads of a pacemaker.
