Abstract
Objective: Tiger stripes sign is the high amplitude band-like signal noted on Doppler spectral recordings of valvular regurgitation. This is noted most often in patients with porcine mitral prosthetic valves and may be indicative of flail prosthetic leaflet. We herein describe a patient with tiger stripes sign in a severe mitral regurgitation on native valve associated with Ostium secundum atrial septal defect (ASD). Methods: Tiger stripes sign is the high amplitude band-like signal noted on Doppler spectral recordings (pulsed and continuous both) of valvular regurgitation. Other conditions associated with tiger stripes sign are any intracardiac oscillating mass and paraprosthetic leak. The mechanism of its formation is still not clear. In our case, tiger stripes sign was present in a patient with severe mitral regurgitation on native valve associated with ostium secundum atrial septal defect. The purpose of this report is to help us better understand the pathophysiological mechanism of this sign. Results: A 41-year-old woman hospitalized for progressively worsening exertional dyspnea NYHA (New York Heart Association) class III associated with chest pain evolving for the past 3 years. The patient’s medical history includes Grave’s disease. Clinical examination revealed a grade 5/6 blowing holosystolic murmur at the apex and a grade 4/6 blowing murmur at the tricuspid area. ECG showed Atrial Fibrillation. Echocardiography showed the presence of severe mitral regurgitation, severe tricuspid regurgitation and secundum atrial septal defect with 10 mm diameter. Doppler showed the appearance of tiger stripes sign in continuous-wave doppler (CW) and in pulsed-wave doppler (PW) on the mitral valve. Conclusions: The presence of regurgitation with divergent jet associated with ASD can favor the appearance of the tiger stripes sign.
