Key result
Male patients undergoing aortic valve replacement for isolated aortic stenosis had a significantly higher incidence of perioperative transient higher-degree atrioventricular block compared to females (25% vs 0%, p=0.049).
Why the study?
Does female sex protect against perioperative ischemic-reperfusion injury in adult patients undergoing stenotic aortic valve replacement compared to male sex?
Cohort (n=38)

Does female sex protect against perioperative ischemic-reperfusion injury in adult patients undergoing stenotic aortic valve replacement compared to male sex?
Female hypertrophied myocardium appears more resistant to ischemia-reperfusion injury during aortic valve replacement, evidenced by a lower incidence of perioperative transient higher-degree AV block compared to males.

Bešík et al. (2009) conducted a cohort in Isolated aortic stenosis (n=38). Male sex vs. Female sex was evaluated on Perioperative transient higher-degree atrioventricular block (AVB II/III) (p=0.049). Male patients undergoing aortic valve replacement for isolated aortic stenosis had a significantly higher incidence of perioperative transient higher-degree atrioventricular block compared to females (25% vs 0%, p=0.049).
