Uma mulher de 55 anos procurou atendimento médico com queixas de palpitações, dor torácica atípica e dispnéia ao esforço, com duração de 12 meses. O eletrocardiograma revelou hipertrofia ventricular esquerda. O ecocardiograma Doppler transtorácico confirmou hipertrofia de câmaras esquerdas e detectou a presença de valva aórtica quadri, com válvulas de mesmo tamanho, e fluxo regurgitante central moderado. No ecocardiograma, a valva quadrivalvular é identificada por sua forma característica em "X" durante a diástole e aspecto retangular durante a sístole. Os sintomas de insuficiência cardíaca provavelmente são causados por insuficiência valvar, em decorrência de coaptação anormal das válvulas. Em vista da possibilidade de aumento da regurgitação, a paciente foi submetida a controle ecocardiográfico periódico. Observou-se melhora dos sintomas com o tratamento. A 55-year-old woman seeks medical attention with palpitations, atypical chest pain and dyspnea upon exertion, lasting for 12 months. ECG showed left ventricular hypertrophy. Transthoracic Doppler echocardiogram confirmed hypertrophy of the left chambers and showed a quadricuspid aortic valve, with equal-sized cusps, in addition to a moderate regurgitant central flow. Upon echocardiography, the quadricuspid valve is identified by its characteristic "X" form during diastole and rectangular aspect during systole. Heart failure symptoms are presumably caused by valve insufficiency due to abnormal leaflet coaptation. Considering the possibility of progressive regurgitation, follow up on the patient was performed with periodic echocardiographic control. Symptoms responded to treatment
