Abstract:
Bleeding is an occurrence stemming from complex interactions encountered in cardiac surgery and is often attributed to the perioperative administration of anti-thrombotic products if inadequate surgical haemostasis is excluded. Very occasionally, bleeding does not fit the norm and the aetiology is not a lack of surgical prolene or an iatrogenic-induced coagulopathy. Patients who present for cardiac surgery should be questioned carefully for a history of bleeding; however, patients at risk are not always identified. This case presents a series of haemorrhagic events incorrectly labelled as surgical complications resulting from an uncommon but not insignificant undiagnosed condition. The existing literature outlining protocols to safely manage patients with haemophilia during the perioperative cardiac surgical period is discussed in this report. This case explicitly demonstrates the importance of preoperative identification to avoid the morbidity that can result from cardiac surgery in an undiagnosed haemophilic patient.

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...
Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
