Liver cirrhosis is associated with hyperdynamic circulation which can result in heart failure. Transjugular intrahepatic portosystemic shunt (TIPS) due to increase of cardiac output is a stressful stimulus for cardiovascular system. Therefore, new methods for early detection of heart failure are needed. Transmitral flow is a marker of diastolic dysfunction.
To analyze short- and long-term effect of TIPS procedure on transmitral flow.
55 patients (38 men and 17 women, 55.6 ± 8.9 years) with liver cirrhosis treated with TIPS were enrolled in the study. Echocardiography was performed before, 24 h, 7, 30 and 180 days after the procedure. During 6 month follow up 22 patients died. Results. Left ventricle end-diastolic diameter was increasing during the follow-up [baseline: 47 (44.7-51.2) mm, day 7: 50 (46.5-51.3) mm, p < 0.05; day 30: 49.5 (46.7-55.2) mm, p < 0.01; 6 months: 52.5 (48.3-55.2) mm, p < 0.01)]. The peak early filling velocity (E) was significantly increasing [before: 75.5 (60.5-87.3) cm/s, 24 h: 88 (74.3-109.7), p < 0.01; day 7: 89 (81.5-105) p < 0.01; 1 month: 94 (82.7-108.5) p < 0.01; 6 month: 91 (80.1-120.2) p < 0.01]. Peak late atrial filling velocity (A) significantly increased within 24 h after the procedure: 85.1 (76.2-99.5) vs. 91.2 (81.5-104.5) cm/s, p < 0.05. The E/A ratio was increasing during the follow up (baseline: 0.88, 24 h after: 0.89, 1 week: 1.0, 30 days: 1.13, 6 month: 1.06 p < 0.01).
Hemodynamic changes following TIPS procedure can be monitored using echocardiography. Transmitral flow analysis can serve as a useful tool for evaluating of diastolic function in these patients.
肝硬化与高动力循环有关,可导致心力衰竭。经颈静脉肝内门体分流术(TIPS)由于心输出量增加是心血管系统的应激刺激。因此,需要新的方法来早期检测心力衰竭。二尖瓣血流是舒张功能障碍的标志物。
分析 TIPS 术对二尖瓣血流的短期和长期影响。
55 例(男 38 例,女 17 例,55.6±8.9 岁)肝硬化患者行 TIPS 治疗,术前、术后 24 h、7、30 和 180 天进行超声心动图检查。在 6 个月的随访中,22 例患者死亡。结果。左心室舒张末期直径在随访过程中增加[基线:47(44.7-51.2)mm,第 7 天:50(46.5-51.3)mm,p<0.05;第 30 天:49.5(46.7-55.2)mm,p<0.01;6 个月:52.5(48.3-55.2)mm,p<0.01]。早期充盈峰速度(E)明显增加[术前:75.5(60.5-87.3)cm/s,术后 24 h:88(74.3-109.7),p<0.01;第 7 天:89(81.5-105),p<0.01;第 1 个月:94(82.7-108.5),p<0.01;第 6 个月:91(80.1-120.2),p<0.01]。术后 24 h 内晚期心房充盈峰速度(A)明显增加:85.1(76.2-99.5)vs.91.2(81.5-104.5)cm/s,p<0.05。E/A 比值在随访期间增加(基线:0.88,术后 24 h:0.89,1 周:1.0,30 天:1.13,6 个月:1.06,p<0.01)。
TIPS 术后血流动力学变化可通过超声心动图监测。二尖瓣血流分析可作为评估此类患者舒张功能的有用工具。
