Abstract:
Transcatheter aortic valve implantation (TAVI) through a peripheral arterial access is often complicated by concomitant arteriopathy. We describe here the first successful case of TAVI through the carotid artery in Japan. The patient was an 83-year-old woman with severe aortic stenosis (AS). Preoperative computed tomography (CT) revealed a shaggy distal aortic arch and left subclavian artery ostium, along with severely calcified bilateral iliofemoral arteries. Trans-apical and direct aortic approaches were abandoned because of frailty. Following the thorough cerebrovascular assessment, the left common carotid artery was selected for arterial access and a CoreValve transcatheter aortic valve was successfully implanted without neurologic complications.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
