Key result
Posterior aortoplasty for AVR in narrow ostia yields ~5% hospital mortality and reduces LVOT gradients.
Why the study?
To evaluate the possibilities of a new approach to the reconstruction of the root and ascending aorta in aortic valve replacement.
Does posterior aortoplasty during aortic valve replacement improve hemodynamics and survival in patients with a narrow aortic ostium?
Observational (n=132)

Does posterior aortoplasty during aortic valve replacement improve hemodynamics and survival in patients with a narrow aortic ostium?
The original posterior aortoplasty method for aortic valve replacement in patients with a narrow aortic ostium effectively reduces the transvalvular gradient with an acceptable hospital mortality rate.
May support posterior aortoplasty in narrow aortic ostium; hypothesis-generating and requires randomized trials before practice change.
132 patients with isolated aortic valve disease with narrow aortic ostium who underwent surgery in the Institute from 1 May 2009 to 01 Jan 2019 are included in the study group. Among 132 patients, 6 died at the hospital stage (hospital mortality – 4.5%). There were no negative remarks to the surgical technique in any case. Changes in echo data during the hospital stay: systolic pressure gradient across the left ventricular outflow tract (LVOT) before operation was 105.1±11.5 mmHg, with 25.9±4.1 mmHg on the aortic prosthesis upon discharge. Reconstruction of the root and ascending aorta according to the proposed method in cases of aortic hypoplasia and aortic valve replacement (AVR) is highly effective intervention. The purpose of this research is to study possibilities of a new approach to the reconstruction of the root and ascending aorta in AVR.

Попов et al. (2019) conducted an observational in Isolated aortic valve disease with narrow aortic ostium (n=132). Original method of posterior aortoplasty for aortic valve replacement was evaluated on Hospital mortality. An original method of posterior aortoplasty for aortic valve replacement in patients with a narrow aortic ostium yielded a hospital mortality of 4.5% and reduced the LVOT gradient to 25.9 mmHg.
