BACKGROUND: Alterations in ventricular loading conditions lead to changes in action potential duration via mechanoelectrical feedback. A decrease in load immediately leads to prolongation of repolarization. QT interval and QT dispersion were measured to determine the long-term effect of changes in ventricular systolic load on the ventricular repolarization. METHOD: Corrected QT interval and QT dispersion were measured in 26 patients before and 3-6 months after valvuloplasty for pulmonary stenosis. To determine the effect of ventricular load on ventricular repolarization, patients were divided in 2 groups; Group 1 was those patients with a greater than 30 mmHg and Group 2 was those patients with a less than 30 mmHg decrease in right ventricular systolic pressure. RESULTS: Corrected QT interval (412.6+/-14.5 msec vs 426.4+/-16.8 msec, p < 0.05) and QT dispersion (35.0+/-7.3 msec vs 45.7+/-14..1 msec, p < 0.05)were increased significantly only in Group 1 after vlavuloplasty. CONCLUSION: It suggested that mechanoelectrical interactions are operative for long duration in humans that changes in ventricular load after successful pulmonary valvuloplasty showed long-term effect on the ventricular repolarization.

6.Monitored Anesthetic Care of Percutaneous Mitral Balloon Valvuloplasty for Severe Mitral Stenosis during Pregnancy: A case report.
Korean Journal of Anesthesiology 2006;51(1):124-126
A woman presented severe mitral stenosis at 34 weeks' gestation. She did not respond to medical therapy, and underwent successful percutaneous mitral balloon valvuloplasty with monitored anesthetic care. The remainder of her pregnancy was uncomplicated, and she delivered a healthy infant at 38 weeks' gestation. We proved monitored anesthetic care is available method in percutaneous mitral balloon valvuloplasty for severe mitral stenosis during pregnancy.

Percutaneous balloon valvuloplasty is considered the standard of care for treatment of valvular pulmonic stenosis, a common congenital defect in dogs. Supravalvular pulmonic stenosis is a rare form of pulmonic stenosis in dogs and standard treatment has not been established. Although, there have been reports of successful treatment of supravalvular pulmonic stenosis with surgical and stenting techniques, there have been no reports of balloon dilation to treat dogs with this condition. Here, a case of supravalvular pulmonic stenosis diagnosed echocardiographically and angiographically in which a significant reduction in pressure gradient was achieved with balloon dilation alone is presented.

BACKGROUND: There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy. However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral balloon valvotomy. METHODS: In this study, we assessed 15 patients (mean age, 47.7+/-9.7 years; 11 female and 4 male) who underwent mitral valve repair between August 2008 and March 2013 for symptomatic mitral valve restenosis after percutaneous mitral balloon valvotomy. The mean interval between the initial percutaneous mitral balloon valvotomy and the mitral valve repair was 13.5+/-7 years. The mean preoperative Wilkins score was 9.4+/-2.6. RESULTS: The mean mitral valve area obtained using planimetry increased from 1.16+/-0.16 cm2 to 1.62+/-0.34 cm2 (p=0.0001). The mean pressure half time obtained using Doppler ultrasound decreased from 202.4+/-58.6 ms to 152+/-50.2 ms (p=0.0001). The mean pressure gradient obtained using Doppler ultrasound decreased from 9.4+/-4.0 mmHg to 5.8+/-1.5 mmHg (p=0.0021). There were no early or late deaths. Thromboembolic events or infective endocarditis did not occur. Reoperations such as mitral valve repair or mitral valve replacement were not performed during the follow-up period (39+/-16 months). The 5-year event-free survival was 56.16% (95% confidence interval, 47.467-64.866). CONCLUSION: On the basis of these results, we could not conclude that mitral valve repair could be an alternative for patients with mitral valve restenosis after percutaneous balloon mitral valvotomy. However, some patients presented with results similar to those of mitral valve replacement. Further studies including more patients with long-term follow-up are necessary to determine the possibility of this application of mitral valve repair.

BACKGROUND: Because its efficacy and percutaneous approach, percutaneous mitral ballon valvotomy(PMV) could be an alternative to surgery for mitral restenosis after surgical commissurotomy, somewhat decreasing the mortality and morbidity associated with second thoracotomy. This study assesses the efficacy of PMV in patients with mitral restenosis after surgical commissurotomy compared with in patients without prior surgery. METHODS: PMV were performed in 367 patients to compare the effectiveness between patients with mitral restenosis after surgical commissurotomy(group 1, n=22) and patients with unoperated mitral stenosis(group 2, n=345). Twenty two had undergone closed or open mitral commissurotomy average 11.2 years before. RESULTS: There were no significant differences in clinical profiles between two groups. Mitral valve area was increased from 1.0+/-0.8 to 1.8+/-0.6cm2 in group 1 and 0.9+/-0.3 to 2.0+/-0.7cm2 in group 2(p>0.05). Mitral gradient was decreased from 14+/-5.9 to 6+/-2.6mmHg in group1 and 18+/-7.0 to 7+/-5.3mmHg in group2(p>0.05). Increment of mitral regurgitation and significant left to right shunt after PMV were not significantly different(10% versus 14.7%, 5% versus 10.4% respectively, p>0.05). Optimal results defined as final valve area more than 1.5cm2 with gain a more than 25% of initial valve area were attained in 75% of patients in group1 and in 84.3% of group 2 patients(p>0.05). CONCLUSIONS: PMV in mitral restenosis after surgical commissurotomy may be safe in selected patients and equally effective as in unoperated mitral stenosis.

Percutaneous mitral balloon valvuloplasty (PMBV) is the treatment of choice for mitral stenosis. Only a few reported cases have been reported in PMBV patients worldwide. In this study, a case of a 34 year-old female with infective endocarditis a year after PMBV is presented. The patient presented with fever, and peripheral vascular symptoms. Transthoracic echocardiography showed vegetation on the anterior mitral leaflets and Staphylococcus Viridans was isolated from blood cultures. The patient was successfully treated with Amoxicillin + Clavulate and Gentamicin. Further studies on the correlation between PMBV and infective endocarditis are needed.
