Abdominal Aortic Aneurysm
The aorta is the main blood vessel that carries blood throughout the body. An abdominal aortic aneurysm (AAA) occurs when an area of the aorta becomes enlarged or balloons out. If the aneurysm becomes large enough, it may rupture.
Abnormal Heart Rhythms (Arrhythmias)
Each year millions of people experience abnormal heart rhythms (arrhythmias), which are common as we age. For most, a normal resting heart rate is 60 to 100 beats per minute (bpm). For athletic individuals, a normal resting heart rate may be as low as 40 to 60 bpm.
Acute and Chronic Aortic Dissection
Aortic dissection is defined as acute within 14 days after onset of symptoms. This definition is used in trials and in clinical practice. In contrast to patients with acute complications, such as rupture, rapid enlargement and malperfusion, patients with chronic dissection are treated for aneurysm formation.
Anterior Cruciate Ligament (ACL) Injury
As an injury that is commonly found in those who participate in high-intensity sports like basketball, football and soccer, an anterior cruciate ligament injury (ACL) affects roughly 250,000 people a year in the United States alone.
Aortic Transection
This condition occurs when the aorta tears or ruptures. The degree of injury can range from minimal bruising of the aorta to complete separation and rupture.
