摘要 目的:评价经皮球囊二尖瓣成形术(PBMV)患者的近期和长期疗效,并探讨老年二尖瓣狭窄(MS)或伴有重度肺动脉高压患者行PBMV的可行性。方法:对210例PBMV患者术前、后及其中80例患者随访10-14年的有关心脏参数进行分析、比较。结果:PBMV成功率99%(210/212)。210例患者行PBMV后即刻疗效:(1)二尖瓣面积(MVA)术前、后分别为(0.89±0.35)和(2.18±0.37)cm^2(P〈0.01);(2)二尖瓣跨瓣压差(MPG)分别为(14.9±5.1)和(7.1±1.8)mmHg.(P〈0.01);(3)左房压(LAP)分别为(26.1±13.8)和(11.6±5.2)mmHg,(P〈0.01);(4)术后心功能改善1级以上占100%,2级以上占85.8%。80例患者长期疗效:(1)MVA术前、后和随访10~14年分别为(0.83±0.35),(2.26±0.32)和(1.56±0.27)cm^2.与术前比较P〈0.01;(2)MPG分别为(16.1±4.8),(6.8±2.5)和(10.3±3.2)mmHg,与术前比分别为P〈0.01.P〈0.05;(3)心功能改善1级以上占87.8%;2级以上占60.3%;45例伴有重度肺动脉高压患者,术后肺动脉压从(67±15)mmHg下降至(47±16)mmHg.半年后继续降至(34±8)mmHg,P〈0.01。结论:二尖瓣狭窄患者PBMV近期疗效和长期疗效满意,伴有肺动脉重度高压者或者老年人也是PBMV的适应证。 Objective: To assess the early and long-term effects of PBMV, and study the availability of PBMV in patients with serious pulmonary hypertension or in the aged. Methods: The cardiac data of 210 patients before and after PBMV, and 80 patients follow-up 10-14 years were retrospectively analyzed. Results: Achievement ratio of PBMV was 99% (210/212 cases). The early effect of 210 patients (compared before and after PBMV) : (1) Mitral valve area (MVA): (0.89±0.35) vs. (2.18±0.37) cm^2 (P〈0.01); (2) Mitral pressure gradient (MPG): (14.9± 5.1) vs. (7.1 ±1.8) mmHg (P〈0. 01); (3) Left atrial pressure (LAP): (26.1±13.8) vs. (11.6±5.2) mmHg (P〈0. 01); (4) The ratio of patients with heart function improved 1 grade reached 100%, and improved more than 2 grades reached 85.8 %. The long-term effect of 80 patients (compared before and after PBMV, follow up 10- 14years): (1) MVA.. (0.83±0.35) vs. (2.26±0.32), vs. (1.56±0.27) cm^2 (P〈0. 01); (2) MPG; (16.1 ±4. 8) vs. (6. 8±2.5), vs. (10.3±3.2) mmHg (P〈0.01, P〈0.05 respectively) ; (3) The ratio of heart function improved≥1 grade was 87.8% and ≥2 grades was 60. 3%. The pulmonary pressure of 45 patients with serious pulmonary hypertension decreased from (67±15) to (47±16) mmHg (P〈0. 01) and to (34±8) mmHg after half year (P〈0.01). Conclusion: PBMV is exciting treatment for MS, and is also adapted to aged MS patient or complicated serious pulmonary hypertension.
