Lord Hunt of Everest presented with aortic stenosis but predominant ri
ght ventricular failure. He was found to have signs of pulmonary hyper
tension with a dilated right ventricle, severe tricuspid regurgitation
, and right atrial hypertrophy in the absence of elevated pulmonary ar
tery pressures. He is a lifelong mountaineer and we attribute these fi
ndings to intermittent prolonged exposure to high altitude. (C) 1998 b
