The paradoxes of the aortic valveThe valve opens before the presence offorward flowEjection continues even after the aorticpressure exceedes ventricular pressureThe aortic valve already starts closing duringe ao t c a e a eady sta ts c os g du gejection
Answer:a-b = rapid valve opening; b-c = slow systolic closure; c-d = rapid valve closing; RVOT = rapid valve opening time; RVCT= rapid valve closing time; ET = ejection time; D1 = maximal leaflet displacement; SCD = slow closing displacement; D2= leaflet displacement before rapid valve closingSchematic drawing of an M-mode tracing describing the measured aortic valveopening and closing features
