Michigan Aortic Club, the big MAC, at STS 2026 in New Orleans. Very proud of our graduates of the aortic fellowship program.

@pomyers @VictorDayan1 That’s beyond me. Mean Gradient has been 5-7 mmHg when patients awake during follow up. We copied directly from echo reports. The measurements of gradient have been consistent in patients

@BoYangMD @VictorDayan1 There is also no reason for gradients to go down over time per ASE/EACVI: with a subaortic velocity (V1) >1.5 m/s, it should be deducted from V2 to calculate the aortic valve gradient using the modified Bernouilli equation. With my limited understanding, I'm surprised

Interesting data. Although I would love to accept this data outright, there are things I can’t understand. EAO increase from 2.2 to 2.9 ??? What is the physiological explanation. Never see it. Probably due to survival or in this case “follow-up” bias ? Maybe @BoYangMD can explain

SAVR +Y-incision AAE outperforms TAVR in hemodynamics in low-intermediate risk patients with severe AS during 3 years f/u. see our paper in JTCVS ENDO, (Fig below: mean G and EOA; PPM.) jtcvsstructural.org/action/showPdf…

@pomyers @VictorDayan1 We plan to continue to follow those pts for 10-20 years and see long term outcomes. Also collaborating with our echocardiographer to review the all the Echos.

@BoYangMD @VictorDayan1 Any echocardiographers to provide more insights? This doesn't seem right to me, but glad to learn. LVOT diameter should be measured per ASE/EACIV just below the prosthetic ring, and as this is in the fibrous body, LV remodelling can't influence it...

@pomyers @VictorDayan1 The echo data of the TAVR group were from the same clinical lab. In the study, TAVR is smaller than the native annulus, is the limiting factor of flow. The EOA is quite consistent in TAVR group.

@pomyers @VictorDayan1 The echo data are from the clinical echo labs who are completely blinded to this retrospective study. Size 27 and 29 valves. Have diameter above 2 cm and area above 3 cm2. Area of Normal human aortic annulus is 3-5 cm2. I am not surprised.

@VictorDayan1 EOA is calculated from LVOT, with the regression of LVH, the LVOT increases about 10% in our follow up data, the EOA continued to increase. With large valves, size 29, 27, the valve is not limiting factor of flow. With small valves, the limiting factor is always the valve.

@BoYangMD Interesting data. Could you share your insights as to the reason for a 30% increase in EOA in one year ?

@BoYangMD No one adult ever came for a to small aortic annulus (without AS) either. It’s complex but I don’t think it’s a problem.

With complete transaction of the ascd aorta for Y-AAE, it is very easy to access the MV through the dome of LA since MV is right underneath the root. This approach can be used for concomitant MV repair, replacement or LA Maze, LAA excision.

Deep dissection is critical to achieve a competent aortic valve in David procedure. It can be challenging when the R cor sinus is ventricularized and VAJ is high. This video shows how to perform deep dissection without worry about RVOT injury for perfect David procedure.

@dixiebarca Those are just half of our aortic cases. We mores than enough aortic cases for two aortic fellows.
