The choice between SAVR and TAVR often relies on the open-heart surgical risk and indications for other open heart surgeries (etc., coronary bypass, other valve dysfunction). The Bentall procedure is a type of surgical procedure when the aortic valve, aortic root, and ascending aorta are replaced in a single operation.
The ligamentum arteriosum (arterial ligament), also known as Botallo's ligament, Harvey's ligament, and Botallo's duct, [1] is a small ligament attaching the aorta to the pulmonary artery. [clarification needed] It serves no function in adults but is the remnant of the ductus arteriosus formed within three weeks after birth. [clarification needed]
The truncus arteriosus and bulbus cordis are divided by the aorticopulmonary septum.The truncus arteriosus gives rise to the ascending aorta and the pulmonary trunk.The caudal end of the bulbus cordis gives rise to the smooth parts (outflow tract) of the left and right ventricles (aortic vestibule & conus arteriosus respectively).

The aortic sac or aortic bulb [1] is a dilated structure in mammalian embryos, lined by endothelial cells and is the most distal part of the truncus arteriosus. [2] It is the primordial vascular channel from which the aortic arches arise (and eventually the dorsal aortae) and is homologous to the ventral aorta of gill-bearing vertebrates.
An aortic sinus, also known as a sinus of Valsalva, [1] is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve.These widenings are between the wall of the aorta and each of the three cusps of the aortic valve.
The ductus arteriosus, also called the ductus Botalli, named after the Italian physiologist Leonardo Botallo, is a blood vessel in the developing fetus connecting the trunk of the pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs.
The first and second arches disappear early. A remnant of the 1st arch forms part of the maxillary artery, [3] a branch of the external carotid artery. The ventral end of the second develops into the ascending pharyngeal artery, and its dorsal end gives origin to the stapedial artery, [3] a vessel which typically atrophies in humans [4] [5] but persists in some mammals.
The tunica media is made up of smooth muscle cells, elastic tissue and collagen.It lies between the tunica intima on the inside and the tunica externa on the outside.. The middle coat (tunica media) is distinguished from the inner (tunica intima) by its color and by the transverse arrangement of its fibers.
