Clinical features and surgical outcomes of membranous subaortic stenosis in three siblings: a case series and literature review.

INTRODUCTION

Subvalvular aortic stenosis (SAS) is a rare heart condition that can cause LVOT obstruction and lead to serious complications. While surgery is the main treatment, recurrence is a concern. This case series highlights the challenges in managing SAS in young patients.

CASE SERIES

Three young brothers presented with symptoms of shortness of breath and chest tightness. All were diagnosed with membranous SAS through echocardiography and Doppler ultrasound. Surgical intervention was performed to remove the obstruction, but all three patients experienced recurrence within 2 years.

DISCUSSION

This case series of three brothers suggests a genetic predisposition. Symptoms included exertional dyspnea and chest tightness, diagnosed via echocardiography. Surgical intervention is the primary treatment, but its timing is debated due to recurrence risks and complications.

CONCLUSIONS

This case series suggests a possible genetic predisposition to SAS. Despite successful initial surgery, the high recurrence rate highlights the need for improved management strategies and long-term follow-up. Further research is crucial to understand the causes of recurrence and optimize treatment for children with SAS.
