@OuzounianMD @CircAHA Impressive numbers. Congrats. #tssmn #adultCS

@OuzounianMD We more aggressively enlarge the annulus. Target: Female 23mm prosthesis, male 25mm. Many patients in Germany want to avoid Warfarin, they rather risk redo procedures or VIVIVIV. #tssmn #adultCS

@OuzounianMD @ritamilewski Thx Maral. Good to hear from you again.#tssmn #adultCS

Thx for inviting us. Interesting talk. #tssmn

@OuzounianMD It's the era of TAVI. We rarely implant mechanical valves in aortic position (5-10 out of 250 aortic cases). #tssmn #adultCS

@drnikkistamp I think, the extend is often a question. Do I have to do the arch, you are running out of time for playing in the root area. #tssmn #adultCS

@OuzounianMD No. Type of prosthesis do not influence aortic site decision. #tssmn #adultCS

@OuzounianMD @drchrismerry @drnikkistamp @ritamilewski We directly cannulate the ascending aorta and resect the cannulation site in HCA. By using a AnteFlo prosthesis (prosthesis with one 8 mm perfusion branch), early reperfusion can be initiated easily without leaving a "culprit lesson" at the aorta.

@drchrismerry @drnikkistamp @ritamilewski ACP is especially for learners the best opinion. No hurry during anastomosis. #tssmn #adultCS

@drnikkistamp @ritamilewski Always ACP at our center. #tssmn #adultCS

@OuzounianMD I think, we just got the tip of the problem. We still cannot differ between valve diseases affecting the aorta and aortic diseases affecting the valve. #tssmn #adultCS

@OuzounianMD Embryologically, the proximal arch is originating from the neural crest as well. Thus, we extend into the proximal arch much more aggressive than some years ago. #tssmn #adultCS

@OuzounianMD Studies from Girdauskas and Borger have shown that BAV stenotic valve have the same risk of aortic dilation than TAV stenotic valves. #tssmn #adultCS

@drchrismerry #tssmn #adultCS Well, wall thickness is a quite soft variable. Difficult to define and often differently interpreted. Not really useful for guidance.

@OuzounianMD I totally agree. LVEF is one of our main trigger factors reducing operative extend.

#tssmn #adultCS Hi everyone, I am Sven Peterss, CT surgeon from Germany. Thx for the invitation to join this session "tonight".
