alpha-stat management
pH management strategy during hypothermic cardiopulmonary bypass that maintains uncorrected arterial pH at 7.40.
inotrope
A medication that alters the force of cardiac muscle contraction, either increasing (positive) or decreasing (negative)...
lusitropy
The property of myocardial relaxation; positive lusitropy enhances diastolic relaxation while negative lusitropy impairs...
LVAD
Left ventricular assist device providing mechanical circulatory support for patients with severe heart failure.
milrinone
Phosphodiesterase-3 inhibitor providing both positive inotropic and vasodilatory effects for cardiac support.
mixed venous oxygen saturation
The oxygen saturation of blood returning to the heart, measured in the pulmonary artery as an indicator of tissue oxygen...
modified ultrafiltration
A blood concentration technique performed after separation from cardiopulmonary bypass to remove excess fluid.
myocardial edema
Accumulation of fluid within the cardiac muscle tissue, often occurring during cardiopulmonary bypass or reperfusion.
myocardial hibernation
A protective state of chronically reduced myocardial function in response to persistent hypoperfusion, potentially rever...
myocardial ischemia monitoring
Continuous surveillance for signs of inadequate coronary perfusion using multiple diagnostic modalities during cardiac s...
myocardial lactate extraction
The difference between arterial and coronary sinus lactate concentrations, indicating myocardial metabolic state and oxy...
myocardial oxygen consumption
The rate at which the myocardium consumes oxygen, primarily determined by heart rate, contractility, and wall tension.
myocardial oxygen supply-demand balance
The critical relationship between myocardial oxygen delivery and consumption that determines whether cardiac tissue rece...
myocardial protection
Strategies and techniques used during cardiac surgery to minimize heart muscle damage during periods of ischemia.
myocardial revascularization
Surgical restoration of blood flow to ischemic heart muscle through bypass grafting or other techniques.
myocardial stunning
Temporary myocardial dysfunction following ischemia-reperfusion that recovers over time.
OPCAB
Off-pump coronary artery bypass surgery performed on a beating heart without cardiopulmonary bypass.
pH-stat blood gas management
Blood gas management strategy that maintains pH at 7.40 and PaCO2 at 40 mmHg when corrected to patient's actual temperat...
postoperative bleeding
Excessive blood loss following cardiac surgery, often requiring transfusion or surgical intervention.
preload optimization
Strategic fluid management to achieve optimal ventricular filling pressures before cardiac surgery.
pressure-volume loop
A graphical representation of the cardiac cycle showing the relationship between ventricular pressure and volume through...
protamine reversal
The administration of protamine sulfate to neutralize heparin anticoagulation following cardiopulmonary bypass.
pulmonary vascular resistance
The resistance against blood flow through the pulmonary circulation, measured as PVR.
pulsatile flow
Blood flow that maintains physiologic pressure variations during cardiopulmonary bypass, as opposed to non-pulsatile rol...
pump prime
The initial filling of the cardiopulmonary bypass circuit with fluid before connecting to the patient.
