Abstract
Background Balloon mitral valvotomy is a standard therapeutic modality for managing rheumatic mitral stenosis. Data on intermediate outcomes of this procedure are limited. Thus we investigated the intermediate outcome after balloon mitral valvotomy performed at a large tertiary center in India. Methods Case records and follow-up data of 2330 patients who underwent valvotomy from June 1999 to December 2005 were retrieved from the hospital information system and analyzed. Results The median age of the patients was 32 ± 11 years, 1363 were female including 36 who were pregnant, and 379 were in atrial fibrillation. Follow-up ranged from 1 to 14 years (mean 4.5 years, median 4.0 years). The procedural success rate was 93%. Atrial fibrillation, higher functional class, and worse valve morphology were independent predictors of a poor procedural outcome. Patients with sinus rhythm had better event-free survival (10.43 years, 95% confidence interval: 10.1–10.7) compared to those with atrial fibrillation (8.17 years, 95% confidence interval: 7.5–8.8). Patients who achieved a valve area >1.75 cm2 had a better event-free survival (11.7 years, 95% confidence interval: 11.4–12.0) than those with a valve area of 1.5–1.74 cm2 (9.3 years, 95% confidence interval: 9.0–9.7). On multivariate analysis, higher functional class, worse valve morphology, and new significant mitral regurgitation were predictors of a poor outcome. Achieved mitral valve area >1.75 cm2 was an independent predictor of a good outcome. Conclusion Patients with sinus rhythm, less gross valve deformity, and a post-balloon mitral valvotomy area >1.75 cm2 had better intermediate outcomes.

Abstract
BACKGROUND The purpose of this study was to examine the influence of atrial fibrillation (AF) on the immediate and long-term outcome of patients undergoing balloon mitral valvotomy (BMV). HYPOTHESIS Patients with atrial fibrillation fair poorly after balloon mitral valvotomy. METHODS There were a total of 818 consecutive patients who underwent elective BMV in this institute from 1997 to 2003, with either double-lumen or triple-lumen BMV catheters included in the study. Of them, 95 were with AF. The clinical, echocardiographic, and hemodynamic data of these patients were compared with those of 723 patients in normal sinus rhythm (NSR). Immediate procedural results and long-term events were compared between the 2 study groups. RESULTS Patients with AF were older (39.9 ± 9.9 years vs 29.4 ± 10.1, P < 0.001) and presented more frequently with New York Heart Association (NYHA) class III-IV (53.7% vs 32.9%, P < 0.001), echocardiographic score >8 (47.4% vs 24.9%, P < 0.001), and with history of previous surgical commissurotomy (33.7% vs 11.5%, P < 0.001). In patients with AF, BMV resulted in inferior immediate and long-term outcomes, as reflected in a lesser post-BMV mitral valve area (1.3 ± 0.4 vs 1.6 ± 0.4 cm(2), P = 0.032) and higher event rate on follow-up. CONCLUSIONS Patients with AF were older, sicker, and had advanced rheumatic mitral valve disease. They had a higher incidence of stroke, new onset heart failure, and need for reinterventions on long-term follow-up. These patients need intense and more frequent follow-up.

Abstract
BACKGROUND Long-term follow-up after percutaneous mitral commissurotomy enables predictive factors of late results to be identified. METHODS AND RESULTS Late results of percutaneous mitral commissurotomy were assessed in 1024 consecutive patients. Good immediate results, defined as valve area ≥1.5 cm(2) without mitral regurgitation >2/4, were obtained in 912 patients (89%). These 912 patients were randomly split into 2 cohorts comprising 609 and 303 patients that were used to develop and validate, respectively, a scoring system predicting late functional results. The 20-year rate of good functional results (survival without cardiovascular death, mitral surgery, or repeat percutaneous mitral commissurotomy and in New York Heart Association class I or II) was 30.2 ± 2.0%. A multivariable Cox model identified 7 predictive factors of poor late functional results: higher final mean gradient (P<0.0001), interaction between age and final mitral valve area (P<0.0001) showing that the impact of valve area decreases with age, interaction between sex and valve calcification (P<0.0001) showing that the impact of valve anatomy is stronger in men, and interaction between rhythm and New York Heart Association class showing an impact of New York Heart Association class only in patients in atrial fibrillation (P<0.0001). A 13-point score enabled 3 risk groups to be defined, corresponding to predicted good functional results of 55.1%, 29.1%, and 10.5% at 20 years in the validation cohort. CONCLUSIONS Twenty years after percutaneous mitral commissurotomy in a population of patients with varied characteristics, 30% still had good functional results. Prediction of late functional results is multifactorial and strongly determined by age and the quality of immediate results. A simple validated scoring system is useful for estimating individual patient outcome.

Abstract
Percutaneous balloon dilatation of stenotic cardiac valves is used for the treatment of pulmonic, mitral, aortic, and tricuspid stenosis. Percutaneous mitral balloon valvuloplasty (PMV) has been used successfully as an alternative to open or closed surgical mitral commissurotomy in the treatment of symptomatic rheumatic mitral stenosis. PMV produces good immediate hemodynamic outcome, low complication rates, and clinical improvement in the majority of patients. PMV is safe and effective and provides clinical and hemodynamic improvement in rheumatic mitral stenosis. PMV is the preferred form of therapy for relief of mitral stenosis for a selected group of patients with symptomatic mitral stenosis.

Abstract
Percutaneous mitral balloon valvuloplasty (MBV) was introduced in 1984 by Inoue who developed the procedure as a logical extension of surgical closed commissurotomy. Since then, MBV has emerged as the treatment of choice for severe pliable rheumatic mitral stenosis (MS). With increasing experience and better selection of patient, the immediate results of the procedure have improved and the rate of complications declined. When the reported complications of MBV are viewed in aggregate, complications occur at approximately the following rates: mortality (0-0.5%), cerebral accident (1-2%), mitral regurgitation (MR) requiring surgery (1.6-3%). These complication rates compare favorably to those reported after surgical commissurotomy. Several randomized trials reported similar hemodynamic results with MBV and surgical commissurotomy. Restenosis after MBV ranges from 4% to 70% depending on the patient selection, valve morphology, and duration of follow-up. Restenosis was encountered in 31% of the author's series at mean follow-up 9 ± 5.2 years (range 1.5-19 years) and the 10, 15, and 19 years restenosis-free survival rates were (78 ± 2%) (52 ± 3%) and (26 ± 4%), respectively, and were significantly higher for patients with favorable mitral morphology (MES ⩽ 8) at 88 ± 2%, 67 ± 4% and 40 ± 6%), respectively (P < 0.0001). The 10, 15, and 19 years event-free survival rates were (88 ± 2%, 60 ± 4% and 28 ± 7%, respectively, and were significantly higher for patients with favorable mitral morphology (92 ± 2%, 70 ± 4% and 42 ± 7%, respectively (P < 0.0001). The effect of MBV on severe pulmonary hypertension, concomitant severe tricuspid regurgitation, left ventricular function, left atrial size, and atrial fibrillation are addressed in this review. In addition, the application of MBV in specific clinical situations such as in children, during pregnancy and for restenosis is discussed.

Abstract
Clinical and echocardiographic data of 547 consecutive patients (mean age, 31.5 years) undergoing mitral balloon valvuloplasty with follow-up of 1.5–19 years, were analyzed. Immediately after valvuloplasty, mitral valve area increased significantly from 0.92 ± 0.17 to 1.95 ± 0.29 cm2. Restenosis occurred in 169 (31%) patients; it was less common (20%) in those with a mitral echocardiographic score ≤8. Actuarial freedom from restenosis at 10, 15, and 19 years was 78% ± 2%, 52% ± 3%, and 26 ± 4%, respectively, and significantly higher in patients with echocardiographic scores ≤8: 88% ± 2%, 67% ± 4%, and 40% ± 6%, respectively. Event-free survival at 10, 15, and 19 years was 88% ± 2%, 60% ± 4%, and 28% ± 7%, respectively, and significantly higher in patients with echocardiographic scores ≤8: 92% ± 1%, 70% ± 4%, and 42% ± 7%, respectively. Multivariate analysis identified echocardiographic score ≤8 and post-procedure valve area ≤1.8 as predictors of restenosis, and echocardiographic score > 8 and preexisting atrial fibrillation as predictors of combined events. Valvuloplasty provides excellent results in selected patients with mitral stenosis. The long-term outcome can be predicted from the baseline characteristics of the mitral valve.

Abstract
There is no doubt that percutaneous transvenous mitral commissurotomy (PTMC) in experienced centers is associated with a low risk of major complications and yields excellent immediate and long-term outcome. Although previous observational studies on both PTMC and surgical commissurotomy have indicated similar outcome between the two treatment strategies in terms of valve area improvement and risk of major complication (death, thromboembolism and significant resultant mitral regurgitation), it was not until recently that several prospective randomized trials comparing the two procedures and involving > 470 patients with favorable valve characteristics (pliable, noncalcified valve with mild subvalvular disease and no or mild mitral regurgitation), have confirmed that PTMC is indeed just as, if not more, effective as surgical commissurotomy. The late restenosis rate at up to 3-year follow-up appears comparable. Furthermore, PTMC has other additional benefits. It is nontraumatic, may be repeated without additional risk, and has been shown to be an extremely useful and efficacious palliative tool in those with end-stage mitral stenosis or with unfavorable valve anatomy who refuse surgery, and in certain subset of patients at high surgical risk because of medical comorbidities.

Abstract
OBJECTIVES To assess the long-term results (up to 16.5 years) of mitral balloon valvuloplasty (MBV) and to identify predictors of restenosis and event-free survival. METHODS AND RESULTS We report the immediate and long-term clinical and echocardiographic results in 518 patients, mean age 31 +/- 11 years, who underwent successful MBV for severe mitral stenosis (MS) and were followed up for 0.5-16.5 (mean 6 +/- 4.5) years. After MBV, mitral valve area (MVA) increased from 0.84 +/- 0.2 to 1.83 +/- 0.53 cm(2) (P < 0.0001) as measured by catheter and from 0.92 +/- 0.17 to 1.96 +/- 0.29 cm(2) (P < 0.0001) as measured by two-dimensional echo. Restenosis occurred in 111 patients (21%) and it was less frequent in patients with low echo score (11%). Actuarial freedom from restenosis at 5, 10, 15 years was 85 +/- 1%, 70 +/- 3%, and 44 +/- 5%, respectively, and was significantly higher in patients with low echo score. Event-free survival (death, redo MBV, mitral valve replacement, New York Heart Association [NYHA] functional class III or IV) at 5, 10, 15 years was 89 +/- 1%, 79 +/- 2%, 43 +/- 9%, respectively, and was significantly higher for patients with low echo score. Cox regression analysis identified mitral echocardiographic score (MES) > 8 (P < 0.0001), postprocedure mitral valve area (MVA) (P = 0.0015), and preprocedure functional class (P = 0.014) as predictors of restenosis and MES (P < 0.0001) and age (P < 0.0001) and postprocedure MVA (P = 0.015) as predictors of event-free survival. CONCLUSIONS MBV provides excellent long-term results for selected patients with MS. The long-term outcome after this procedure can be predicted from baseline clinical and echocardiographic characteristics.

Abstract
PURPOSE To evaluate long-term survival and valve-related complications as well as prognostic factors for mid- and long-term outcome after closed mitral commissurotomy, covering a follow-up period of 14 years. MATERIAL AND METHODS Between 1989 and 2003, 36 patients (28 women and 8 men, mean age 28.8 +/- 6.1 years) underwent closed mitral commissurotomy at our institution. The majority of patients were in New York Heart Association (NYHA) functional class IIB, III, or IV. Indication for closed mitral commissurotomy was mitral stenosis. Closed mitral commissurotomy was undertaken with a Tubbs dilator in all cases. Median operating time was 2.5 hours +/- 30 minutes. RESULTS After closed mitral commissurotomy, the mitral valve areas of these patients were increased substantially, from 0.9 to 2.11 cm(2). No further operation after initial closed mitral commissurotomy was required in 86% of the patients (n = 31), and NYHA functional classification was improved in 94% (n = 34). Postoperative complications and operative mortality were not seen. Follow-up revealed restenosis in 8.5% (n = 3) of the patients, minimal mitral regurgitation in 22.2% (n = 8), and grade >or=3 mitral regurgitation in 5.5% (n = 2) patients. No early mortality occurred in closed mitral commissurotomy patients. Reoperation was essential for 5 patients following closed mitral commissurotomy; 2 procedures were open mitral commissurotomies and 3 were mitral valve replacements. No mortality occurred in these patients. CONCLUSIONS The mitral valve area was significantly increased and the mean mitral valve gradient was reduced in patients after closed mitral commissurotomy. Closed mitral commissurotomy is a safe alternative to open mitral commissurotomy and balloon mitral commissurotomy in selected patients.

Abstract
Percutaneous balloon mitral commissurotomy (PBMC) is now first-line therapy in patients with symptomatic mitral stenosis (MS) and favorable valve morphology. Unfortunately, the outcome of Medicare-aged patients undergoing this procedure has not previously been defined. The results of PBMC in 55 patients > or = 65 years old (71 +/- 6 years) with moderate or severe MS were compared with 268 younger patients (47 +/- 10). Preprocedural New York Heart Association functional class and pulmonary pressures did not differ. The older patients had higher blood pressure, were more likely to be in atrial fibrillation and had higher valve scores (9.9 +/- 2.5 vs 8.6 +/- 2.2, p = 0.001). Procedural success was higher in the younger group (71% vs 55%, p = 0.013), with a greater increase in mitral valve area. Complications were similar in both groups and there were no periprocedural deaths. At 6 months a significant improvement in function class was seen in both groups. Restenosis, as assessed by serial echocardiography, occurred at a rate of 0.06 cm(2)/year in both groups, and functional class remained unchanged over 3 years. Event-free survival was similar at 48 months: 76% in the younger group and 69% in the older group. Our data thus demonstrates that PBMC can be safely performed in the Medicare-aged population. Despite less acute success in the older population, complication rates do not differ and decrement in valve area over time occurs at a similar rate. Functional class remains improved and event-free survival over 4 years appears similar in both groups. PBMC should thus be offered to patients with MS and suitable anatomy regardless of their age.

Abstract
The aim of this study was to assess late results of percutaneous mitral commissurotomy (PMC) in calcific mitral stenosis and to identify predictors to improve patient selection. We analyzed 422 patients who underwent PMC for calcific mitral stenosis. The extent of calcium was graded from 1 to 4 by fluoroscopy: 227 patients (53%) were graded 1, 125 (30%) graded 2, 55 graded 3 (13%), and 15 graded 4 (4%). The procedure failed in 15 patients, used a single balloon in 11, a double balloon in 126, and the Inoue balloon in 270. In-hospital mortality was 1.2%. Good immediate results (valve area >/=1.5 cm(2) without mitral regurgitation >2/4), were obtained in 321 patients (76%). Multivariate analysis identified 5 predictors of good immediate results: a younger age (p = 0.0004), a lesser degree of stenosis (p = 0.0005), a smaller extent of calcium (p = 0.04), the use of the Inoue balloon (p = 0.015), and a larger effective balloon dilating area (p = 0.006). Good functional results, defined as survival with no further intervention and in New York Heart Association class I or II, were 36 +/- 4% at 8 years. The predictors of good functional results after good immediate results were a younger age (p = 0.04), a lower pre-PMC New York Heart Association class (p <0.0001), sinus rhythm (p = 0.0006), a smaller extent of calcium (p = 0.02), and a lower gradient after PMC (p <0.0001). Despite a frequent deterioration on follow-up after PMC for calcific mitral stenosis, the predictive analysis suggests that PMC may be useful in deferring surgery in selected patients with mild to moderate calcific deposits, who have otherwise favorable characteristics.

Abstract
OBJECTIVES The results of percutaneous mitral commissurotomy were assessed in patients with restenosis after surgical commissurotomy. BACKGROUND Balloon dilation is feasible in patients with restenosis after surgical commissurotomy, but little is known about its late efficacy. METHODS We studied 232 patients who had undergone percutaneous mitral commissurotomy a mean of 16 +/- 8 years after surgical commissurotomy. Mean age was 47 +/- 14 years; 81 patients (35%) had valve calcification. All patients had restenosis with bilateral commissural fusion as assessed by echocardiography. Technical failure occurred in 9 patients and the procedure used a single balloon in 7 patients, a double balloon in 95, and the Inoue balloon in 121. RESULTS Complications were death in 1 patient (0.4%) and mitral regurgitation >2/4 in 10 (4%); 191 patients (82%) had good immediate results (valve area > or =1.5 cm2 without regurgitation >2/4). Predictors of poor immediate results in multivariate analysis were older age (p < 0.001), lower initial valve area (p = 0.01) and the use of the double-balloon technique (p = 0.015). In the 175 patients who underwent follow-up, 8-year survival without operation and in New York Heart Association class I or II was 48 +/- 5%, and 58 +/- 6% after good immediate results. In this latter group, poor late functional results were predicted by higher cardiothoracic index (p < 0.0001), previous open-heart commissurotomy (p = 0.05) and lower final valve area (p < 0.0001) in a multivariate Cox model. CONCLUSIONS Percutaneous mitral commissurotomy is safe and provides good immediate results in selected patients with restenosis after surgical commissurotomy. After good immediate results, the conditions of more than half of the patients remained improved at 8 years, enabling reoperation to be deferred.

Abstract
BACKGROUND The objective of this study was to evaluate long-term survival, valve-related complications as well as prognostic factors for early and late outcome after open and closed mitral commissurotomy covering a follow-up period of 35 years. METHODS From 1955 to 1977, 183 patients with mitral stenosis underwent mitral commissurotomy at our institution. Closed valvotomy was performed on 143 patients (group A) and open valvotomy on 40 patients (group B). RESULTS Survival rates after 10, 20, and 30 years were 89%, 67.8%, and 49.1% in group A and 91.7%, 66.7%, and 45.9% in group B (p = not significant). The risk of late death increased significantly with an advanced preoperative New York Heart Association functional class, atrial fibrillation, higher age at operation, pre- or postoperative mitral regurgitation, and leaflet calcification. Forty-four patients in group A and 5 patients in group B required reoperation (p < 0.05). Independent predictors for reoperation in a multivariate analysis were a remaining postoperative mitral stenosis or regurgitation. A total of 68 patients showed valve-related complications. The linearized rate of valve-related morbidity and mortality was 2.1% per patient-years in group A versus 1.1% per patient-years in B (p < 0.01). CONCLUSIONS Long-term survival for open and closed commissurotomy are excellent, showing no difference between the groups. However, both the incidence of reoperation as well as valve-related morbidity and mortality were significantly lower after open commissurotomy. In well-selected patients with pure mitral stenosis and no leaflet calcification, open commissurotomy still remains a valid surgical option.

Abstract
OBJECTIVES The purpose of this study was to examine the effect of atrial fibrillation (AF) on the immediate and long-term outcome of patients undergoing percutaneous mitral balloon valvuloplasty (PMV). BACKGROUND There is controversy as to whether the presence of AF has a direct negative effect on the outcome after PMV. METHODS The immediate procedural and the long-term clinical outcome after PMV of 355 patients with AF were prospectively collected and compared with those of 379 patients in normal sinus rhythm (NSR). RESULTS Patients with AF were older (62 +/- 12 vs. 48 +/- 14 years; p < 0.0001) and presented more frequently with New York Heart Association (NYHA) class IV (18.3% vs. 7.9%; p < 0.0001), echocardiographic score >8 (40.1% vs. 25.1%; p < 0.0001), calcified valves under fluoroscopy (32.4% vs. 18.8%, p < 0.0001) and with history of previous surgical commissurotomy (21.7% vs. 16.4%; p = 0.0002). In patients with AF, PMV resulted in inferior immediate and long-term outcomes, as reflected in a smaller post-PMV mitral valve area (1.7 +/- 0.7 vs. 2 +/- 0.7 cm2; p < 0.0001) and a lower event free survival (freedom of death, redo-PMV and mitral valve surgery) at a mean follow-up time of 60 months (32% vs. 61%; p < 0.0001). In the group of patients in AF, severe post-PMV mitral regurgitation (> or =3+) (p = 0.0001), echocardiographic score >8 (p = 0.004) and pre-PMV NYHA class IV (p = 0.046) were identified as independent predictors of combined events at follow-up. CONCLUSIONS Patients with AF have a worse immediate and long-term outcomes after PMV. However, the presence of AF by itself does not unfavorably influence the outcome, but is a marker for clinical and morphologic features associated with inferior results after PMV.

Abstract
Long-term (>3 years) follow-up data were obtained from 102 consecutive patients undergoing percutaneous mitral balloon valvotomy (PMBV). Data were collected prospectively by review of the medical record, mailed questionnaire, and/or telephone. Data on patients with closed mitral commissurotomy (CMC) at our institution have been previously reported and serve as the comparison group. Follow-up data was 98% complete at a mean of 57 months for PMBV patients. Compared with patients undergoing CMC, these patients were older (54+/-14 vs 43.6+/-10 years, p <0.001) and more likely to have undergone previous mitral valve surgery (17% vs 4%, p <0.001). The observed 5-year survival in the PMBV group was no different from that observed in the CMC group (83% vs 90%, p = NS) or from that predicted by the model developed from the CMC patients. Commissural calcium was associated with death and death or repeat mitral valve procedure in the multivariate analysis. Long-term survival free from repeat procedures was equivalent when patients with commissural calcium were excluded. Thus, PMBV offers long-term survival and freedom from subsequent mitral valve procedures similar to CMC.

Abstract
BACKGROUND The optimal use of percutaneous mitral commissurotomy (PMC) in a wide range of patients requires accurate evaluation of late results and identification of their predictors. METHODS AND RESULTS Late results of PMC were assessed in 1024 patients whose mean age was 49+/-14 years. Echocardiography showed that 141 patients (14%) had pliable valves and mild subvalvular disease, 569 (55%) had extensive subvalvular disease, and 314 (31%) had calcified valves. A single balloon was used in 26 patients, a double balloon in 390, and the Inoue Balloon in 608. Good immediate results were defined as valve area >/=1.5 cm2 without regurgitation >2/4 (Sellers' grade) and were obtained in 912 patients. Median duration of follow-up was 49 months. The 10-year actuarial rate of good functional results (survival with no cardiovascular death and no need for surgery or repeat dilatation and in New York Heart Association [NYHA] class I or II) was 56+/-4% in the entire population. Follow-up echocardiography was available in 90% of the patients who experienced poor functional results after good immediate results and showed restenosis in 97% of these. In multivariate analysis, the predictors of poor functional results were old age (P=0.0008), unfavorable valve anatomy (P=0.003), high NYHA class (P<0.0001), atrial fibrillation (P<0.0001), low valve area after PMC (P=0.001), high gradient after PMC (P<0.0001), and grade 2 mitral regurgitation after PMC (P=0.04). CONCLUSIONS PMC can be performed with good late results in a variety of patient subsets. Prediction of late events is multifactorial. Knowledge of these predictors can improve patient selection and follow-up.

Abstract
BACKGROUND The objective of this study was to assess the long-term clinical outcome and valvular changes (area and regurgitation) after percutaneous mitral valvuloplasty (PMV). METHODS AND RESULTS After PMV, 561 patients were followed up for 39 (+/-23) months and clinical/echocardiographic data obtained yearly. Kaplan-Meier and Cox regression analyses were performed to estimate event-free survival, its predictors, and the relative risks of several patient subgroups. There were several nonexclusive events: 19 (3.3%) cardiac deaths, 55 (9.8%) mitral replacements, 6 (1%) repeated PMVs, 56 (10%) cases of restenosis, and 108 (19%) cases of clinical impairment. Survival free of major events (cardiac death, mitral surgery, repeat PMV, or functional impairment) was 69% at 7 years, ranging from 88% to 40% in different subgroups of patients. Wilkins score was the best preprocedural predictor of mitral opening, but the procedural result (mitral area and regurgitation) was the only independent predictor of major event-free survival. Mitral area loss, though mild [0.13 (+/-0.21)cm2], increased with time and was >/=0.3 cm2 in 12%, 22%, and 27% of patients at 3, 5, and 7 years, respectively. Regurgitation did not progress in 81% of patients, and when it occurred it was usually by 1 grade. CONCLUSIONS Seven years after PMV, more than two thirds of patients were in good clinical condition and free of any major event. The procedural result was the main determinant of long-term outcome, although a high score had also negative implications. Mitral area decreased progressively over time, whereas regurgitation did not tend to progress.

Abstract
BACKGROUND Percutaneous balloon mitral commissurotomy (BMC) has been proposed as an alternative to surgical closed mitral commissurotomy (CMC) and open mitral commissurotomy (OMC) for the management of rheumatic mitral valve stenosis (MS). METHODS AND RESULTS We conducted a prospective, randomized trial comparing the results of the 3 procedures in 90 patients (30 patients in each group) with severe pliable MS. Cardiac catheterization was performed in all patients before and at 6 months after each procedure. All patients had clinical and echocardiographic evaluation initially and throughout the 7-year follow-up period. Gorlin mitral valve area (MVA) increased much more after BMC (from 0.9+/-0.16 to 2.2+/-0.4 cm2) and OMC (from 0.9+/-0.2 to 2.2+/-0.4 cm2) than after CMC (from 0.9+/-0.2 to 1.6+/-0.4 cm2). Residual MS (MVA <1.5 cm2) was 0% after BMC or OMC and 27% after CMC. There was no early or late mortality or thromboembolism among the three groups. At 7-year follow-up, echocardiographic MVA was similar and greater after BMC and OMC (1.8+/-0.4 cm2) than after CMC (1.3+/-0.3 cm2; P<.00l). Restenosis (MVA <1.5 cm2) rate was 6.6% after BMC or OMC versus 37% after CMC. Residual atrial septal defect was present in 2 patients and severe grade 3 mitral regurgitation was present in 1 patient in the BMC group. Eighty-seven percent of patients after BMC and 90% of patients after OMC were in New York Heart Association functional class I versus 33% (P<.0001) after CMC. Freedom from reintervention was 90% after BMC, 93% after OMC, and 50% after CMC. CONCLUSIONS In contrast to surgical CMC, BMC and OMC produce excellent and comparable early hemodynamic improvement and are associated with a lower rate of residual stenosis and restenosis and need for reintervention. However, the good results, lower cost, and elimination of drawbacks of thoracotomy and cardiopulmonary bypass indicate that BMC should be the treatment of choice for patients with tight pliable rheumatic MS.

Abstract
BACKGROUND The goal of the present study was to determine the intermediate-term survival and the independent predictors of survival and event-free survival for patients who undergo catheter balloon commissurotomy (CBC). METHODS AND RESULTS CBC for the treatment of mitral stenosis was performed in 132 patients from 1986 through 1994. The use of CBC increased the mitral valve area (MVA) from 1.0 +/- 0.3 to 1.9 +/- 0.6 cm2 (P < .001). There were six early deaths (4.5%) up to 1 month after CBC ("hospital" deaths). In the past 4.5 years, there have been no hospital deaths. Four late deaths occurred after elective mitral valve replacement (MVR). Actuarial 7-year survival was 95 +/- 1%; when mortality after MVR is included, 7-year survival was 83 +/- 6%. Actuarial 1-, 3-, 5-, and 7-year event-free survival (survival without MVR or repeat CBC) was 80 +/- 4%, 77 +/- 4%, 65 +/- 6%, and 65 +/- 6%. On multivariate analysis, the only two independent predictors (both after CBC) of 7-year event-free survival were MVA of > or = 1.5 versus < 1.5 cm2 (75 +/- 7% versus 32 +/- 12%) and mean pulmonary artery wedge pressure of < or = 18 versus > 18 mm Hg (84 +/- 6% versus 38 +/- 11%) (P < .001 for both). Patients with MVA of > or = 1.5 cm2 (n = 96) could be further subdivided into high- and low-risk subgroups for 7-year event-free survival by two post-CBC variables: mean pulmonary artery wedge pressure of < or = 18 versus > 18 mm Hg (90 +/- 6% versus 48 +/- 14%) (P = .0002) and cardiac index of > or = 2.5 versus < 2.5 L.min-1.m-2 (82 +/- 8% versus 61 +/- 13%) (P = .004). Patients with post-CBC MVA of < 1.5 cm2 (n = 24) had no additional predictors of event-free survival. Of patients who did not undergo MVR or repeat CBC, 8% were in New York Heart Association functional class III and 92% were in class I or early class II at the last follow-up. CONCLUSIONS The rates for intermediate-term survival and event-free survival after CBC are very encouraging. Most patients without events were asymptomatic or minimally symptomatic. Thus, in selected patients with mitral stenosis who require an interventional procedure, CBC is the procedure of choice at centers with physicians who have experience and skill in performing this procedure.

Abstract
OBJECTIVES This study sought to assess late functional results after successful percutaneous mitral commissurotomy and to determine their predictors. BACKGROUND Few studies have reported late results of percutaneous mitral commissurotomy or have analyzed their late results regardless of immediate results, despite the fact that late deterioration may well be related either to a decrease in valve area or to poor initial results. METHODS Between 1986 and 1992, 528 patients underwent successful percutaneous mitral commissurotomy (mean [+/- SD] age 46 +/- 18 years; mean follow-up 32 +/- 18 months). A successful procedure was defined by a mitral valve area > or = 1.5 cm2 and no regurgitation > 2/4. Dilation was performed using a single balloon in 13 patients, a double balloon in 349 and the Inoue balloon in 166. Multivariate analysis was performed with a Cox model. RESULTS The survival rate for patients in New York Heart Association functional class I or II, with no cardiac-related deaths or need for mitral surgery or repeat dilation, was 76 +/- 6% at 5 years. By multivariate analysis, the independent predictors of good functional results were echocardiographic group (p = 0.01), functional class (p = 0.02) and cardiothoracic index (p = 0.005) before the procedure and valve area after the procedure (p = 0.007). The predictive model derived allowed estimation of the probability of good functional results according to the value of these four predictors for any given patient. CONCLUSIONS Good functional results were observed 5 years after successful percutaneous mitral commissurotomy in a large series of varied patients. The analysis of predictive factors may provide useful indications for follow-up results in patients undergoing this technique.

Abstract
Despite the established role of percutaneous balloon mitral valvuloplasty (BMV) in the treatment of mitral stenosis, major controversial issues in the realm of BMV persist. With increased operator experience, BMV has now been extended to include various controversial scenarios, such as mild mitral stenosis, adverse valve morphologies, and high-risk patients with concomitant anatomic distortions which are technically demanding. In skilled hands, however, BMV has yielded a favorable outcome in these settings. Furthermore, the debate on whether the Inoue or the double-balloon approach is superior continues. Studies to date have shown equal efficacy of the two BMV methods in terms of valve enlargement although the Inoue approach is clearly simpler to execute and may potentially be associated with a lower risk of creating severe mitral regurgitation. Last, because of the lack of consensus on optimal balloon sizing for BMV, perhaps the best method to adopt at this stage is one that is simple and safe to apply across a broad spectrum of valve anatomy.
