Cardioplegic infusion

Aortic Surgery without Infusion of Cardioplegic Solution at Total Circulatory Arrest

BACKGROUND MINIMAL INFUSION OF CARDIOPLEGIC SOLUTION (CPS) DURING AORTIC SURGERY USING TOTAL CIRCULATORY ARREST (TCA) MAY REDUCE SEVERAL POTENTIAL SIDE EFFECTS: clamping on a diseased aorta, insult of coronary ostia, and edema. MATERIALS AND METHODS From 2006 to 2009, 72 patients underwent aortic surgery without infusion of cardioplegic solution at the initiation of circulatory arrest. The di...

Cardioplegic Strategies for Calcium Control

Background—Ca overload plays an important role in the pathogenesis of cardioplegic ischemia-reperfusion injury. The standard technique to control Ca overload has been to reduce Ca in the cardioplegic solution (CP). Recent reports suggest that Na/H exchange inhibitors can also prevent Ca overload. We compared 4 crystalloid CPs that might minimize Ca overload in comparison with standard Mg-contai...

Left ventricular mechanoenergetics after hyperpolarized cardioplegic arrest by nicorandil and after depolarized cardioplegic arrest by KCl.

We hypothesized that there are no differences in left ventricular (LV) mechanoenergetics between after hyperpolarized cardioplegic arrest by nicorandil (nicorandil arrest) and after depolarized one by high potassium chloride (KCl arrest). The aim of the present study was to test this hypothesis using LV curved end-systolic pressure-volume relation (ESPVR) and linear pressure-volume area (PVA)-m...

Oxygenation of a Crystalloid Cardioplegic Solution

_____________ _ The purpose of this study is to compare the effectiveness of an alternative method of oxygenating a crystalloid cardioplegic solution to the use of a bubble oxygenator. Five hundred milliliters of 100% oxygen was introduced, using sterile technique, into 100 ml bags of Ringer's solution at varying temperatures (20°, 10°, and 4°C). The contents of the bags were shaken for one min...
