The pathophysiology depends on the specific cause of right axis deviation. Most causes can be attributed to one of four main mechanisms. [14] [15] These include right ventricular hypertrophy, reduced muscle mass of left ventricle, altered conduction pathways and change in the position of the heart in the chest. [citation needed]
The LAD gives off two types of branches: septals and diagonals. Septals originate from the LAD at 90 degrees to the surface of the heart, perforating and supplying the anterior 2/3 of the interventricular septum. Diagonals run along the surface of the heart and supply the lateral wall of the left ventricle and the anterolateral papillary muscle.
An aortic aneurysm often doesn’t cause symptoms, but it can lead to severe, sudden bleeding from a ruptured aneurysm. ... Increasing age, with the highest risk after ages 45 in men and 55 in ...
CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. [22] Another major cause of aortic stenosis is the calcification of a congenital bicuspid aortic valve or, more rarely, a congenital unicuspid aortic valve. Those with unicuspid aortic valves typically need intervention ...
Symptoms of the narrowing are pain and numbness within the arms or legs. Another significant location for plaque formation is the renal arteries , which supply blood to the kidneys. Plaque occurrence and accumulation lead to decreased kidney blood flow and chronic kidney disease , which, like in all other areas, is typically asymptomatic until ...

Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart.
