Aortic valve disease and the ST segment/heart rate relationship: A longitudinal study before and after aortic valve replacement

Influence of valve prosthesis type on the recovery of ventricular dysfunction and subendocardial ischaemia following valve replacement for aortic stenosis

“…Early beneficial effects on haemodynamic indices with stentless valves are presumed to result from their low profile [21] and ventricular fractional shortening also improves [22] in patients receiving stentless valves for aortic stenosis or regurgitation. Aortic stenosis is often associated with ST segment depression and T wave inversion in the absence of symptoms or evidence for coronary artery disease [23]. This is generally accepted to represent subendocardial ischaemia at rest that tends to improve following valve replacement.…”
