“…With calculation of the continuity equation, a difference in SV leads to a difference in calculation of the EOA of the mitral valve. 8,9 In our study, calculation using the 2Dbased CSA LVOT of SV led to underestimation of SV by approximately 6% compared with the 3D-planimetered LVOT area. This finding is in agreement with previous reports on the effect of the elliptical shape of the LVOT by observation and calculation of the aortic valve area.…”

Objective This study compared the continuity equation-based effective orifice area (EOA) of prosthetic mitral valves between two-dimensional (2D) and 3D transesophageal echocardiography (TEE). Methods Thirty-four patients without major aortic valve abnormalities underwent mitral valve replacement surgery. The EOAs of prosthetic mitral valves were calculated using the continuity equation with 2D and 3D TEE. For 18/34 patients using a biological valve prosthesis, the EOA of the prosthesis was obtained from commercial records. Results The EOA of prosthetic mitral valves significantly varied between the 2D and 3D methods (2.22 ± 0.71 vs 2.35 ± 0.70 cm2, n = 34). The area of the diameter of the left ventricular outflow tract as determined by the 3D method was significantly higher than that by the 2D method (mean difference: −0.14 ± 0.20 cm2), with 95% coherence boundaries of −0.53 and 0.25 cm2. The regression equation for the EOA by 3D and 2D TEE was y = 0.27 + 0.94x, with a good correlation. Conclusions The EOA of prosthetic mitral valves is underestimated using the 2D TEE method compared with the 3D TEE method. The 3D-TEE method has the advantage of higher precision over the 2D TEE method, and it may be helpful for better assessment of prosthetic mitral valves intraoperatively.

“…124 Meta-analysis demonstrated that the addition of antiplatelet therapy was associated with reduced risk of thromboembolic events with an associated increase in major bleeding. 125,126 Low-dose aspirin in addition to an OAC may be justified in patients with mechanical heart valves. Therefore, dual therapy with an OAC and aspirin may be allowed for those patients with mechanical heart valves complicated by chronic phase of CAD.…”

“…Table 1 lists recommended INR targets for patients with mechanical heart valves. European, US, and NICE recommendations vary, indicating areas of continuing uncertainty, and likely reflecting a lack of high quality evidence 1112. Gradually increase the monitoring interval to weekly, fortnightly, and monthly if INR is stable.…”
