Conversely, if the fetus has reached the point of viability, a prompt birth via Caesarean section offers the best chance of survival. [4] Even if there is no reasonable prospect of maternal resuscitation (for example, after a nonsurvivable injury or prolonged cardiac arrest), the procedure can still serve this purpose.
Caesarean section, also known as C-section, cesarean, or caesarean delivery, is the surgical procedure by which one or more babies are delivered through an incision in the mother's abdomen. It is often performed because vaginal delivery would put the mother or child at risk (of paralysis or even death). [ 2 ]

During a caesarean section, a hysterotomy is utilized to make an incision in the uterus and remove the fetus. [8]

A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side. [1] [2] [3]
Dr. Davis emphasizes that valve damage is not only caused by poor dietary habits, explaining, “Diet is often talked about in connection to heart disease, but valve damage has different causes.
The cardiac skeleton binds several bands of dense connective tissue, as collagen, that encircle the bases of the pulmonary trunk, aorta, and all four heart valves. [2] While not a traditionally or "true" or rigid skeleton, it does provide structure and support for the heart, as well as isolate the atria from the ventricles. This is why atrial ...
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
