PAD is a problem in the circulatory system where your arteries become narrow which leads to less blood flow to your limbs.

heart and circulation. The patient presented with a combination of both congenital and acquired cardiac defects. The diagnosis included congenital bicuspid aortic valve‚ aortic regurgitation juxta-subclavian coarctation‚ stenosis of the left subclavian artery and ruptured sinus of the valsalva aneurysm. This combination of defects is very rare. The patient was weakened by the severity of the defects and the multiple disorders. It was decided to perform the corrective procedure in one surgery. The surgery

condition‚ known as septal rupture‚ leads to significant deformations of the lung architecture that have important functional consequences. The key mechanical event consequent to septal rupture is that the resulting cavity is larger than the sum of the two alveolar spaces‚ because of the lacking mechanical support of the broken septa the lung elastic recoil further enlarges this new space‚ necessarily at the expenses of the surrounding healthy parenchyma. As an immediate consequence of septal rupture‚ the
