A new simplified method for calculating mean mitral pressure gradient.

BACKGROUND: Mean mitral valve pressure gradient (MVPG) is one of the key measures of the severity of mitral stenosis. The method for calculating MVPG, however, is complex and time consuming. The purpose of this study is to establish a new simple method for calculating MVPG. METHODS: Hemodynamic data were analyzed in 105 patients who underwent percutaneous balloon mitral valvuloplasty (PBMV). A new simplified method for calculating mitral pressure gradient was proposed, i.e., mean MVPG = MLAP - LVEDP/2, where MLAP is mean left atrial pressure, and LVEDP is left ventricular end-diastolic pressure. RESULTS: MVPGs derived from the standard and the new method were 13.28 +/- 7.42 mm Hg and 13.50 +/- 7.93 mm Hg, respectively, and there was no significant difference between the values of these two methods (P = 0.065). The MVPG derived from the new simplified method correlated closely with that calculated by the standard approach (r = 0.975, P < 0.001). Moreover, there was no significant difference between mitral valve areas (MVA) derived from the standard and the new approach either before or after PBMV in the 38 patients in whom cardiac output was measured. CONCLUSION: We conclude that mitral pressure gradient can be calculated reliably with our new simplified method.

Abstract：

Objective To observe the outcome and assess related factors affecting left atrial remodeling after percutaneous balloon mitral valvuloplasty (PBMV) in patients with mitral valve stenosis. Methods From March 1998 to June 2002,there were 96 mitral valve stenosis patients who underwent PBMV in our hospital. Echocardiographic,12 leads united electrocardiogram and other clinical datas were collected at preoperation,1 week after operation,and 4-6 years after operation to retrospectiveanalysis. Multiple stepwise regression analysis was used to assess controllable factors of left atrial remodeling. ResultsLeft atrial diameter reduced from (44.6±6.6)cm before PBMV to (42.8±6.5)cm (P>0.05) 1 week after PBMV and enlarged to (47.2±5.7)cm (all P<0.05) at the end of 4-6 years follow up post operation. The mitral valve area (MVA) increased from (1.06±0.32) cm2 before PBMV to (2.02±0.43) cm2 1 week after PBMV and (1.98±0.36)cm2 4-6 years post operation (all P<0.05). Heart function assessed by NYHA classification improved significantly at 1 week and 4-6 years after surgery compared with pre-operation(P<0.01). Multiple stepwise regression analysis showed that systolic blood pressure at 4-6 years after operation, MVA at 1 week after operation, preoperative atrial fibrillation, Wilkins score≤8, preoperative left atrial diameter were the independent predictive factors of left atrial remodeling at 4-6 years after PBMV.Conclusions PBMV was an effective therapy option for patients with mitral valve stenosis.Systolic blood pressure at 4-6 years after operation, MVA at 1 week after operation, preoperative atrial fibrillation, Wilkins≤8, preoperative left atrial diameter are the predictive factors of left atrial remodeling after PBMV.

Abstract：

Objective To evaluate the efficacy and safety of the improved percutaneous balloon mitral valvuloplasty (PBMV) in elderly patients with mitral stenosis. Methods Elderly patients with severe mitral stenosis received an improved PBMV which included a modified way of atrial septal puncture and technique across the mitral valve. The left atrial pressrue (LAP), mean pulmonary pressure (MPA), mean gradient across the mitral value (MPG) and mitral valve area (MVA) were recorded and compared before and after the operation. Long term follow up were made. Results After operation, the LAP decreased [(25.3±6.7) mm Hg vs.(16.4±5.8) mm Hg,1 mm Hg=0.133 Kpa], MPG decreased [(17.6±6.7) mm Hg vs.(6.8±2.9) mm Hg], MPA decreased [(38.6±12.1) mm Hg vs. (29.2±9.8) mm Hg], MVA increased [(1.05±0.22)cm2 vs.(1.61±0.38)cm2] and the New York heart association heart function classification improved. The follow-up result showed that the effect of PBMV was constant. Conclusions Improved PBMV may be an effective and safe measure for patients with mitral stenosis.

Safety and efficacy of percutaneous balloon mitral valvotomy in severe mitral stenosis with moderate mitral regurgitation – A prospective study

BackgroundPercutaneous balloon mitral valvotomy (PBMV) is generally considered as a contraindication in patients with mitral stenosis (MS) associated with moderate to severe mitral regurgitation (MR). We sought to compare the safety and efficacy of PBMV in patients with severe MS and with moderate MR with those with less than moderate or no MR.Materials and methodsSymptomatic patients of MS with mitral valve area ≤1.5 cm² were screened into two groups: Group I with moderate MR and Group II with less than moderate or no MR. Clinical and echocardiographic assessments were done at 24 h, 1 month, and 6 months post-procedure. A treadmill testing was done prior to PBMV and at 6 months.Primary safety outcome was a composite of cardiovascular death and development of severe MR with or without requirement for mitral valve replacement at 30 days of procedure. Efficacy of the procedure was measured as improvement in functional class, treadmill time, and mitral valve area (MVA) at 6 months.ResultsSeventeen patients with moderate MR and 208 patients with less than moderate MR underwent PBMV. Primary outcome showed no significant difference [2 (11.7%) in Group I vs. 8 (3.85%) in Group II, p = 0.36]; occurrence of severe MR was higher in Group I [RR = 4.87, 95% C.I. = 1.42–16.69]. In Group I patients, improvement in treadmill time was seen in 12 (70.59%), functional class in 13 (76.47%), and MVA in all patients.ConclusionIn patients having severe MS associated with moderate MR, PBMV may be a safe option and provides sustained symptomatic benefit.
