Tricuspid valve repair in a mountaineer.

Lord Hunt of Everest presented with aortic stenosis but predominant right ventricular failure. He was found to have signs of pulmonary hypertension with a dilated right ventricle, severe tricuspid regurgitation, and right atrial hypertrophy in the absence of elevated pulmonary artery pressures. He is a lifelong mountaineer and we attribute these findings to intermittent prolonged exposure to high altitude.
