Aorta-to-right atrium fistula, an unusual complication of endocarditis

Infective endocarditis (IE) remains a serious disease. Aorta-to-right atrium fistula is a rare but very serious compli-cation of IE and predicts a higher mortality. This report describes a 50-year-old man with endocarditis, vegetation, perforation of noncoronary sinus, and formation of two aorta-to-right atrium fistulas with native valves detected by transthoracic echocardi-ography. This disease is lethal despite developments in cardiac imaging and antibacterial therapy. Early diagnosis, aggressive antibacterial therapy, and surgical treatment may improve the prognosis.

力竭运动对大鼠心房肌心钠素致密颗粒的影响

对力竭大鼠心房肌细胞的心钠素电子致密颗粒进行了透射电镜观察。结果表明,心钠素电子致密颗粒在有训练游泳力竭组大鼠左、右心房肌细胞大量增加,而无训练游泳力竭组的大鼠,仅右心房肌细胞有少量心钠素颗粒。两力竭组大鼠的心房肌超微结构均出现不同程度的损伤,尤其是无训练游泳力竭组大鼠的心房肌细胞超微结构损伤更严重。
