“…Finally, prompt surgery avoids progressive aortic regurgitation which may develop due to persistently turbulent flow patterns in the LVOT that may cause valve damage. 9) Resection of the accessory tissue and removal of membranous or muscular substrata of obstruction is the standard surgical therapy which allowed, in our experience, for essentially complete relief of LVOT obstruction with no evidence of resultant mitral valve dysfunction.…”

Accessory mitral valve (AMV) is an extremely uncommon congenital cardiac anomaly and it is a rare cause of left ventricular outflow tract (LVOT) obstruction. Identification of asymptomatic patients with LVOT obstruction is uncommon since the symptoms usually become manifest when the gradient across the LVOT rises. We describe a rare case of asymptomatic AMV with severe LVOT obstruction in a 10-year old child with no other congenital or acquired cardiac defects who successful underwent surgery. This case emphasizes the importance of early surgical indication also in absence of symptoms when significant LVOT obstruction occurs.

“…[3,4] Progressively increasing aortic valve regurgitation due to the presence of stenosis also increases the risk for infective endocarditis. [7,12,13] Therefore, the timing of surgery should be planned in patients with discrete subaortic membrane, considering the gradient in the LVOT and progression of the aortic regurgitation.…”

“…Some authors however suggest early surgical excision of SAM to prevent aortic insufficiency or LVH. 9 In developing countries like Pakistan, the patients of SAM usually present after development of symptoms such as easy fatigability, chest pain or syncope attacks. We present here our early results of resection of the sub aortic membrane combined with septal myectomy at CPEIC Multan.…”

ABSTRACT… Objectives:In this study, we presented our results regarding outcomes of surgical correction of sub-aortic membrane. Study Design: Retrospective observational study. Period: June 2012 to June 2017. Setting: CPEIC Multan, Pakistan. Methods: 51 patients operated for resection of sub aortic membrane. The resection of sub aortic membrane was done through the aorta. Evaluation of the aortic valve done in all patients. The aortic valve was either replaced or repaired in cases of severe aortic regurgitation. Associated lesions such as ventricular septal defects (VSD's) were repaired with a dacron patch through the right atrium while ASD's were repaired with a pericardial patch. Post-operative echocardiography was done before discharge and post-op LVOT gradients and aortic insufficiency were recorded for all the patients. Results: There were 36 males and 15 females whose mean ages were 16.29 years. On post-op echocardiography there was no residual significant LVOT gradient in any patient. Three (3) patients developed mild to moderate aortic regurgitation post operatively but none of them warrant any surgical intervention. There was only 1 death in the series which was due to VSD patch dehiscence. None of the patients developed conduction problems post operatively needing any permanent pace maker. Mean pre-op LVOT gradient was 94.7 mmHg while it reduced to 20.7 post operatively (p-value <0.001). Conclusion: We concluded that early resection of sub aortic membrane can be safely accomplished with good results and significant drop in the mean LVOT pressure gradients post operatively. Key words:Left Ventricle Outflow Obstruction, Aortic Regurgitation, Bacterial Endocarditis.

Benefits of Early Surgical Repair in Fixed Subaortic Stenosis

Abstract: The data suggest that surgical resection of fixed subaortic stenosis before the development of a significant (> 40 mm Hg) outflow tract gradient may prevent recurrence, reoperation and secondary progressive aortic valve disease.
