alpha-stat management
pH management strategy during hypothermic cardiopulmonary bypass that maintains uncorrected arterial pH at 7.40.
ACT
Activated clotting time, a point-of-care test measuring blood coagulation status during cardiac surgery requiring antico...
afterload reduction
Pharmacological or mechanical decrease in the resistance against which the heart must pump, typically achieved with vaso...
alpha-stat management
pH management strategy during hypothermic cardiopulmonary bypass that maintains uncorrected arterial pH at 7.40.
antegrade cardioplegia
Delivery of cardioplegic solution through the coronary arteries in the normal direction of blood flow.
aortic cannulation
The surgical insertion of a cannula into the ascending aorta to establish arterial inflow for cardiopulmonary bypass.
aortic cross-clamping
The surgical technique of temporarily occluding the ascending aorta to isolate the heart during cardiac surgery.
aortic elastance
A measure of arterial stiffness representing the change in aortic pressure per unit change in stroke volume.
aortic insufficiency
Backward flow of blood from the aorta into the left ventricle due to incompetent aortic valve.
aortic insufficiency jet
The retrograde flow of blood through an incompetent aortic valve during diastole, visualized on echocardiography as a co...
aortic regurgitation fraction
The percentage of stroke volume that regurgitates back through an incompetent aortic valve during diastole.
aortic root venting
Placement of a catheter or needle in the aortic root to remove air and blood during cardiac procedures.
aortic stenosis gradient
The pressure difference across a stenotic aortic valve, measured as peak or mean gradient.
aprotinin
Antifibrinolytic agent historically used to reduce bleeding during cardiac surgery but withdrawn due to safety concerns.
arterial line dampening
Loss of accurate arterial pressure waveform fidelity due to air bubbles, clots, or kinked tubing in the monitoring syste...
autotransfusion
The process of collecting, processing, and reinfusing a patient's own blood during or after cardiac surgery to reduce al...
bathotropy
The property affecting cardiac excitability; positive bathotropy increases excitability while negative bathotropy reduce...
BIS monitoring
Bispectral index monitoring system that measures brain electrical activity to assess depth of anesthesia.
cardiac index
Cardiac output normalized to body surface area, expressed in liters per minute per square meter.
cardioplegia
A solution used to induce cardiac arrest during heart surgery to protect the myocardium.
cardioplegic arrest
Deliberate cessation of cardiac electrical and mechanical activity using high-potassium solution to protect the myocardi...

The apparatus and tubing used to deliver cardioplegic solution to the myocardium during cardiac surgery for myocardial p...
cardioplegic solution
A specialized preservation fluid used to induce cardiac arrest and protect the myocardium during cardiac surgery procedu...
cardiopulmonary bypass
A surgical technique that temporarily diverts blood circulation away from the heart and lungs during cardiac procedures.
