| Abstract | 「要旨」左房粘液腫6例に平衡時心電図同期心プールシンチグラフィを施行, これにフーリエ変換による位相解析を試み, 左房粘液腫の検出能を検討するとともに, 左室容量曲線の拡張期指標1/3 Filling Fraction, Rapid Filling Fraction, Peak Filling Rateより左室流入障害を評価した. その結果6例中5例に左室基部に位相の遅れを示す部位が存在し, 左室内位相ヒストグラムの標準偏差は大であり, 5例に左室流入障害の存在が示唆された. 粘液腫摘出術後再検査を行った3例は左室基部の位相の遅れが消失し, 拡張期指標は改善した. 以上の結果より, 位相解析は拡張期に左室に嵌入する腫瘤の検出に, 拡張期指標は左室流入障害の把握にそれぞれ有用と考えられた. |

| Abstract | [Summary] Radionuclide imaging plays an important role in diagnosisng left atrial myxoma (LAM). We discussed diagnostic value of Fourier analysis with phase image and evaluated left ventricular filling function using indices such as 1/3 Filling Fraction, Rapid Filling Fraction and Peak Filling Rate derived from left ventricular volume curve. Equillibrium radionuclide angiocardiography was performed in 6 LAM patients. Phase delay in the basal portion of the left ventricle was shown in 5 of 6 LAM patients, and standard deviation of left ventricular phase was larger than these of controls. Left ventricular filling disturbance was suggested in 5 of 6 LAM patients. After surgical remove of myxoma phase delay was disappeared and standard deviation was normalized. And left ventricular filling was improved. We concluded that the phase image of Fourier analysis revealed a left atrial mass prolapsing in the left ventricule during the diastole, and that diastolic indices were useful for left ventricular filling disturbance due to LAM. |
