Abstract:
Patients with sickle cell abnormalities undergoing surgery are generally considered to be at greater risk for perioperative complications. We present a 25-year-old woman with sickle cell disease (SCD) and severe aortic insufficiency. A minimally invasive, warm, beating heart approach was adopted to try and minimize the risk of sickling due to cardiopulmonary bypass (CPB), low-flow states, cold cardioplegia and aortic cross-clamping. Compared to classical methods, we believe our technique further reduces the risk of systemic and organ hypothermia and thus, sickling.

Cardiomyopathy V: Interprofessional Care
Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
