| Abstract | 「要旨」201Tl心筋シンチグラム (TMS) を用いて, 心肥大をきたす各種心疾患患者90名, 健常者29名の心形態について検討した. 6方向左室心筋像のうち長軸がもっとも垂直となる方向を移行面と定義し, 心電図の移行帯と比較した. また, 左前斜位心筋像で, 長径, 短径, 壁厚の計測を行った. その結果, TMSの移行面は, 心電図と比べて心臓の解剖学的位置をより正確に示した. また, 大動脈弁狭窄症および高血圧性心疾患では壁厚の増加, 内腔の球形化および心拡大を示す求心性肥大を示した. 僧帽弁閉鎖不全症 (MR) および大動脈弁閉鎖不全症 (AR) はともに著明な内腔拡張を認める拡張性肥大を呈し, 慢性MRでは球形化, ARでは正常心と類似形, 急性MRは長軸上の著明な伸展を示した. 肥大型心筋症では特異な壁肥厚, うっ血型心筋症では壁の非薄化, 球形を示す拡張性肥大を呈した. 以上のごとく, TMSは心臓の位置, 大きさ, 形状の観察に有用であった. |

| Abstract | [Summary] To evaluate cardiac morphology in the patients with various cases of hypertrophy, we measured left ventricular (LV) size using thallium-201 myocardial scintigraphy in 29 normal subjects and in 90 patients. Cardiac shape and dimension were assessed by measuring the wall thickness and external length in the short and long axis of LV image in LAO projection. In aortic stenosis and hypertensive heart disease the shape was spherical and the wall was thickened. In both mitral (MR) and aortic (AR) regurgitations, LV dilatation were shown ; spherical shape in chronic MR but ellipsoid shape in acute MR and AR. Decreased LV size but normal shape was observed in mitral stenosis and cor pulmonale. In hypertrophic cardiomyopathy the LV wall was asymmetrically hypertrophied, while in congestive cardiomyopathy the wall is thin with marked LV dilatation and the shape was spherical. We concluded that the heart had characteristic configuration which might reflect cardiac performance or compensate for the load to the heart, and that thallium-201 myocardial scintigraphy is useful in the evaluation of cardiac morphology as well as in diagnosis of myocardial ischemia. |
