“…In our series, this occurred in 50% and has varied between 0 and 39.5% for associated congenital mitral regurgitation. [22][23][24] It is possible that the mitral valve may have been amenable to repair in patient 3, reducing this figure to 25%, had there not been avoidable delays in presenting for surgery. Rates of reoperation for mitral valve repair have ranged from 7 to 30%.…”

“…The typical form described by RUCKMAN and VAN PRAAGH [2] is defined by shortened chordae, loss of interpapillary distance and leaflet implantation defects. The more severe forms are those with abnormalities of the papillary muscles according to CARPENTIER et al [8], resulting in more difficult valve reparative procedures. Parachute mitral valve is the most frequent form of this subgroup, associated or not to Shone's complex.…”

Objective: For a cohort of patients with congenital mitral stenosis (CMS), to determine: patient outcomes, predictors of valve repairability and predictors of durability of valve repair. Methods: From 1989 and 2002, 23 patients underwent surgical treatment of CMS, excluding those with common atrioventricular canal, and univentricular forms. The median age at operation was 15.5 months (range 2-204), and the median body weight was 11 Kg (range 4.5-51.6). Seventeen patients (73.9%) had associated anomalies, including Shone's complex in nine (39.1%) and pulmonary hypertension in 14 (60.9%). Mitral stenosis was severe in 14 patients (60.9%) and moderate in the remaining (median trans-mitral gradient of 16 mmHg, range 8.5-32). Mitral valve repair was performed in 18 patients (78.3%), and valve replacement in five (21.7%). Repair techniques included papillary muscle splitting (n=10), excision of supravalvular ring (n=9) and commissurotomy (n=8). Twelve patients (52.2%) required associated procedures.Results: There were no early and late deaths at a mean follow-up of 58.5 ± 46.7 months (range 1-156). Mean hospital stay was 12.7 ± 8.2 days. There were no significant factors associated with unsuccessful valve repair. Actuarial freedom from reoperation at five years was 67.1% (CI 95%: 56.8% to 77.4%). The mitral valve repair group required reoperation in eight patients (44.4%) (two early and six late), as opposed to one (20%) in the replacement group. The presence of preoperative pulmonary hypertension was significantly related (p<0.005) to higher reoperation rates. All but two the followed patients are presently in functional class I and the echocardiography has shown less than 2+ mitral stenosis and/or regurgitation.Conclusion: Reoperations were the most important cause of morbidity at the medium-term follow-up of CMS. Preoperative pulmonary hypertension may predict the need for reoperation after mitral valve repair, which is the procedure of choice in CMS.

“…Carpentier and colleagues reported that when the papillary muscles are basically normal, congenital mitral stenosis may be due to papillary muscle commissure fusion, excess valvular tissue, hypoplasia of the annulus, or supravalvular ring. 3 For treatment of supravalvular mitral ring with severe stenosis, surgical resection is per-…”
