Calcification of the pulmonary valve is a uncommon condition. Non invasive diagnostic methods such as M-mode and two dimensional echocardiography have facilitated the identification of vegetations and calcifications on the pulmonary valve. Very few cases of isolated calcification on the pulmonary valve have been reported; a previous lesion of the valve almost always exists. The purpose of this communication is to report two cases with calcification of pulmonary valves without underlying pathology and to highlight the great utility of echocardiography in diagnosis and follow-up of such cases.
肺动脉瓣钙化是一种罕见的病症。诸如M型和二维超声心动图等非侵入性诊断方法有助于识别肺动脉瓣上的赘生物和钙化。肺动脉瓣孤立钙化的病例报道极少；瓣膜几乎总是存在先前病变。本文的目的是报告两例无潜在病理基础的肺动脉瓣钙化病例，并强调超声心动图在此类病例诊断和随访中的巨大作用。
