Mechanical shifts that cause LAD are expiration or raised diaphragm from pregnancy, ascites (fluid accumulation in the abdomen), abdominal tumor, or enlarged liver or spleen. [2] Left axis deviation is a border deviation in athletes , which, if it is combined with another borderline feature such as right bundle branch block, requires further ...
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.
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]
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.
Infective endocarditis occurs more often in men than in women. [11] There is an increased incidence of infective endocarditis in persons 65 years of age and older, which is probably because people in this age group have a larger number of risk factors for infective endocarditis.

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 ...
In a funny People article in 2004, a family friend commented on the royal's strapping physique in his tiny swimwear. "Physically he is a very strong boy and beautifully proportioned — he takes ...
