The interval time for the St. Thomas cardioplegia solution in mitral valve surgeries.

ABSTRACT:

Background

There is a lack of consensus on the appropriate St. Thomas cardioplegia solution interval for cardiac surgeries. The objective of this study was to determine a safe cardioplegia interval.

Method

A total of 340 patients who underwent mitral valve surgery with St. Thomas solution were assessed and divided into 2 groups according to the average cardioplegia interval. In Group A, the average cardioplegia interval was < = 30 min; in Group B, the average cardioplegia interval was greater than 30 min. Propensity score matching was used to adjust for confounders between the two groups. After propensity score matching, Groups A and B contained 125 patients each. The primary endpoints were creatine kinase MB, left ventricular ejection fraction, and troponin levels after sur
