Introduction Surgical aortic valve replacement (SAVR) is the best established treatment for severe, symptomatic aortic valve stenosis (AS), where it restores life-expectancy to levels seen in the general population.1 Ideally, patients with AS should be followed-up in a valve clinic, so that the optimal timing for performing SAVR can be determined, based on a combination of periodically assessed symptoms, signs, imaging and laboratory tests.2,3 Operating too late carries an increased risk of death and of peri-operative complications, related to (potentially irreversible) deterioration of left ventricular (LV) function from afterload mismatch.

Introduction Syncope is defined as a transient loss of consciousness (TLoC) secondary to cerebral hypoperfusion, associated with loss of tone and spontaneous recovery.1 It has a lifetime prevalence of 20%,2 and an incidence of 0.80–0.93 per 1,000 person-years, which occurs in a roughly bimodal pattern, with an initial peak in early adulthood followed by a further more pronounced peak in older age.3 Syncope is merely one form of TLoC. Other causes of TLoC include seizures, sleep disturbance, accidental falls and some psychiatric disorders. Syncope itself can be grouped into four major categories: reflex syncope (vasovagal and situational), o
