Shone's anomaly describes a complex involving multiple left sided cardiac obstructions, namely, parachute deformity of the mitral valve, supravalvular ring of the left atrium, subaortic stenosis and aortic coarctation. We are reporting a case of Shone's anomaly characterised by aortic recoarctation, mitral supravalvular membrane, bicuspid aortic valve, complicated complete atrioventricular block and bradycardia-induced nonsustained polymorphic ventricular tachycardia. We revealed mitral supravalvular membrane by 3D transoesophageal echocardiography.
