Abstract「要旨」安静時再分布シンチグラムがPTCAの適応決定に有用であった急性心筋梗塞症例を経験した. 症例は72歳, 女性. 左前下行枝#7の99%狭窄に対しPTCRを行い90%となるも, 急性期左室造影では前壁のdyskinesisを認めた. その後, 梗塞後狭心症を頻発したためPTCAの適応を決定する目的で安静時再分布シンチグラムを行ったところ, 前壁の広範なタリウム欠損と, 同部位への明瞭な再分布所見を認めた. PTCA後, 左室壁運動は著明に改善した. PTCA後のタリウムシンチグラムでは欠損部の縮小過程を経時的に観察し得た. 安静時再分布シンチグラムは, 心筋梗塞急性期の心筋のviabilityの評価と, PTCA後の治療効果の判定に有用であった.

Abstract[Summary] A 72-year-old woman with acute myocardial infarction was received coronary thrombolytic therapy. After percutaneous transluminal coronary recanalization (PTCR) , the stenosis of LAD became from 99% to 90%. Left ventriculogram showed dyskinesis of anterior wall in acute phase. After PTCR, she complained of postinfarctional angina. Thus, in order to evaluate the viability of anterior wall, serial thallium scintigraphy was performed at rest, which showed perfusion defect and redistribution of anterior wall. After percutaneous transluminal coronary angioplasty (PTCA) , anterior wall motion became almost normal. The perfusion defect of anterior wall was also gradually disappeared. The serial thallium scintigraphy at rest is an useful method not only to evaluate the viability of myocardium in acute myocardial infarction, but also to follow the effect of PTCA.
