Brief introduction

Bicuspid valve which was followed by aortic valve was viewed as the most susceptive one to rheumatic fever

最常受累为二尖瓣,其次为主动脉瓣

Page 6: Valvular Heart Disease

心脏瓣膜病病因风湿性心脏病 ( 风心病、 rheumatic heart disease)

风湿性炎症过程所致的瓣膜损害主要累及 40岁以下人群我国常见的心脏病之一

瓣膜粘液样变性和老年人瓣膜钙化日益↑VHD comprises a variety of etiologies involving but most cases of it were at one time due to rheumatic heart disease

Mitral stenosis

Page 11: Valvular Heart Disease

Mitral StenosisNatural History

Progressive, life long disease

Usually slow & stable in the early years

Progressive acceleration in the later years

呈进展性病程,往往伴随终生

早期进展较缓慢且稳定

晚期病情加速恶化

Mitral StenosisNatural History

several years latency fever to symptom onset

Additional 10 years before disabling symptoms

感染潜伏多年后出现症状

出现症状后 10 年内可丧失生活能力

Mitral Stenosis: Etiology & pathology

Most adult patients: MS is the result of rheumatic fever

2/3 of patients with MS are female and 1/2of all without history of rheumatic fever

多数成年患者:二狭由风湿热引起

2/3 是女性, 1/2 无风湿热病史

Page 14: Valvular Heart Disease

Mitral Stenosis: Etiology & pathology

Pathological change is inflammation and thickening of leaflet tips that restricts the motion of the tips

Chronic MS LAE & calcification , LA embolization especially accompanied with AF

病理改变:炎症及瓣叶增厚粘连限制瓣膜活动

病因和病理风心病:多伴关闭不全,二尖瓣损害先天性畸形

先天性二叶瓣畸形:瓣膜钙化及瓣口狭窄其他先天性主动脉瓣畸形:单、三叶瓣少见

退行性老年钙化性主动脉瓣狭窄其他少见原因 : 大的赘生物阻塞瓣口

Page 75: Valvular Heart Disease

Aortic Stenosis: Pathophysiology

Normal aortic valve area ≥3.0cm2

Mild stenosis 1.5-2.5 cm2

Moderate stenosis 1.0-1.5 cm2

Severe stenosis < 1.0 cm2

• 成人瓣口变化– 主动脉瓣口≥ 3.0cm2

– 当瓣口面积减少一半时,收缩期仍无明显跨瓣压差– 瓣口≤ 1.0cm2 时, LV收缩压明显,跨瓣压差显著

Page 76: Valvular Heart Disease

病理生理

LV舒张末容量直至失代偿病程晚期才 室壁应力 、心肌缺血和纤维化等致 CHF

压力负荷 LV室壁向心性肥厚LV顺应性, LV舒张末压 , LA后负荷 , LA代偿性肥厚

肥厚 LA舒张末期有力收缩肺 V 和肺毛细血管免于持续的血管内压力

有利于僵硬 LV充盈维持 CO

Page 77: Valvular Heart Disease

主动脉瓣狭窄引起心肌缺血机制氧耗增加: LV壁增厚、心室收缩压

和射血时间延长LV肥厚,心肌毛细血管密度相对舒张期心腔内压力,压迫心内膜下 冠状动脉LV 舒张末压致舒张期 AO-LV差,冠状动脉灌注

Page 79: Valvular Heart Disease

主动脉瓣狭窄引起心肌缺血机制晕厥机制

休息时晕厥由于心律失常致 CO

运动周围血管扩张

狭窄瓣口限制 CO 相应

缺血加重使 LV 功能, CO

LV收缩压急剧,过度激活心室内压力感受器,迷走神经传入纤维兴奋血管减压反应,外周血阻力

运动后即刻发生为突然体循环静脉回流 ,影响心室充盈, CO

以上引起体循环动脉压→脑循环灌注压→脑缺血
