A loud systolic click was heard at the left lower sternal border and xiphisternal area in a 71‐year‐old man. The click showed striking phasic mobility (with reference to first and second heart sound), becoming late systolic in inspiration and early systolic in expiration. Two‐dimensional echocardiography showed tricuspid valve prolapse as well as mild mitral valve prolapse. Continuous‐wave and color flow Doppler recording of the tricuspid regurgitant jet showed marked phasic variation in duration of late systolic tricuspid regurgitation. Phasic respiratory variation in timing of a systolic click is an important auscultatory sign of tricuspid prolapse, serving to distinguish it from mitral prolapse.
