Abstract:
Aortic arch pathologies such as acute aortic dissection and aneurysmal disease represent surgical challenges. Various emerging techniques and surgical prostheses have expanded the therapeutic armamentarium over the last years with one principal objective; to simplify the operation and reduce the surgical time. Besides the classic elephant trunk which has been regarded as an evolutionary leap in the treatment of extensive thoracic disease, other novel surgical approaches such as the frozen elephant trunk, the thoracic endovascular aortic repair (TEVAR) and the hybrid open branched stent grafts have been introduced. This brief review aims to evaluate the surgical alternatives used in the management of complex aortic arch and proximal descending aorta pathologies with particular consideration given to the contemporary approaches which endorse single stage operation.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
