Can left ventricular hypertrophy on electrocardiography detect severe aortic valve stenosis?

ABSTRACT:

Background

Severe aortic stenosis (AS) is increasing in the aging society and is a serious condition for anesthetic management. However, approximately one-third of patients with severe AS are asymptomatic. Echocardiography is the most reliable method to detect AS, but it takes time and is costly.

Methods

Data were obtained retrospectively from patients who underwent surgery and preoperative transthoracic echocardiography (TTE). LVH on ECG was determined by voltage criteria (Sv1 + Rv5 or 6 ≥3.5 mV) and/or the strain pattern in V5 and V6. Severe AS was defined as a mean transaortic pressure gradient ≥40 mmHg or aortic valve area ≤1.0 cm2 by TTE.

Results

Data for 470 patients aged 28-94 years old were obtained. One hundred and twenty-six patients had severe AS. LVH on EC
