MUF could improve pulmonary function after cardiac valve replacement.

改良超滤技术能够改善心脏瓣膜置换术后患者的呼吸动力学。

objective to evaluate the effect of modified ultrafiltration on pulmonary function after cardiac valve replacement.methods 46 patients who underwent mitral valves replacement were randomly divided into muf group(n=24) and control group(n=22) without muf.

目的 观察改良超滤对心脏瓣膜置换术患者肺功能的影响。

Methods Sixty-seven cases of adult patients undergoing valves replacement were randomized into modified ultrafiltration group (n=33) and control group (n=34). Blood gas parameter such as PO2, PCO2 were measured at pre-cardiopulmonary bypass, end CPB, and post MUF (or 20 min post CPB in control group). Ventilatory support time, usage time and amount of vasoactive drug and ejection fraction of left ventricular were also measured in the early period of operation.

67例成人心脏瓣膜置换术患者随机分为MUF组(n=33)和无超滤对照组(n=34)，动态观察体外循环(cardiopulmonary bypass， CPB)前、CPB停机时及MUF结束时（对照组在CPB停机20min）血气氧分压及二氧化碳分压、术后呼吸机辅助呼吸时间、血管活性药物用量及使用时间、心脏射血分数等心肺功能指标。

Objective:To explore multiplane transesophageal echocardiography in the diagnosis of the thrombus in patients with valvular diseases.

目的：探讨多平面经食管超声心动图对心瓣膜病合并心内血栓的诊断价值。

Irregular reddish tan vegetations overlie valve cusps that are being destroyed.

不规则的红棕色疣状赘生物覆盖在主动脉的表面，而引起主动脉瓣膜被损伤。

Objective: To investigate the morphological features of endothelial cells in cardiac valves, pectinate muscles, different arteries and vein segments in dog and provide data for experimental and clinical research of rabbit.

目的：观察狗心脏瓣膜、梳状肌、不同动脉段及静脉内皮细胞的形态学特征，为狗血管的临床和实验研究提供资料。

During the period from the reverse trendelenburg position to the starting point for the closure of the valve, the reverse flow of blood occurred in the experimental group with the velocity of (1.4 ± 0.3) cm/s; while in the control group, there was no reverse flow of blood, but the peak flow rate was decreased from (21.3 ± 2.1) cm/s to (18.2 ± 3.3) cm/s.

动物于头高脚低位至瓣膜开始关闭时，实验组均出现血液返流现象，返流流速（1.4 ± 0.3）cm/s；对照组未出现血液返流现象，但血液流速下降，由高峰流速（21.3 ± 2.1）cm/s 减至（18.2 ± 3.3）cm/s。

A priori of the valve inside vein or posteriority are shut relatively not complete; Vein is embedded scar; Vein flexibility grows along with the age and drop.

静脉内瓣膜先天或后天性相对关闭不全；静脉内含瘢痕；静脉弹性随年龄增长而减退。

Objective: To discuss the diagnosis and treatment of delayed mechanical valve prosthesis dysfunction.

目的：对晚发性机械瓣膜功能障碍的诊断和治疗进行探讨。
