Shone's anomaly: a report of one case in sub-Saharan Africa.

Abstract

Shone's anomaly is a rare congenital cardiac malformation consisting of four obstructive lesions of the left heart and the aortic arch: a supramitral membrane; parachute mitral valve; subaortic stenosis; and coarctation of the aorta which occurs most commonly in its incomplete form. We report on a 17-year-old male Cameroonian with a variant of shone anomaly consisting of sub-valvular aortic stenosis, coarctation of the aorta and parachute mitral valve. He was referred for the investigation of a cardiac murmur after he presented with shortness of breath preceded by flu like syndrome. He underwent successful management abroad consisting of aortic coarctation treatment by percutaneous angioplasty and resection of the subaortic ring by traditional surgical approach without any mitral valve repair. Shone's anomaly is a rare congenital heart disease that can be missed in low resource settings. This case raises awareness about this syndrome, highlights the importance of cardiac ultrasonography in resource limited settings and illustrates the need for comprehensive service frameworks to improve access and level of care and services for patients in the African context.
