Impact of three-dimensional imaging and printing on septal myectomy results-single centre's experience.

Objectives: To assess changes in the results of septal myectomy (SM) following introduction of three-dimensional (3D) imaging and 3D printing in surgical interventions planning and performing in the single-centre settings.

Methods: Between January 2007 and March 2022, 268 consecutive symptomatic patients with hypertrophic obstructive cardiomyopathy and peak pressure gradient at obstruction area ≥50 mmHg underwent conventional SM (n = 112) or SM with heart 3D modelling (n = 156).

Results: For comparative analysis, we used propensity score matching (PSM) by 14 variables and there were formed group 1PSM (conventional SM, n = 77) and group 2PSM (3D-modelled SM, n = 77).

Simultaneous or staged surgery in patients with kidney tumors and concomitant cardiac disease.

Introduction: To evaluate outcomes of simultaneous and staged surgery in patients with kidney tumors and concomitant cardiac disease.

Material And Methods: Between October 2001 and October 2015, fifteen patients (Group 1) underwent simultaneous surgery and fourteen patients (Group 2) underwent staged surgery. 89.

[Surgical treatment of patients with lung cancer involving mediastinum organs with massive invasion in the thoracic aorta by using the extracorporeal circulation].

The patients (11 cases) with massive invasion in the thoracic aorta have been operated in the period from 2002 till 2010. The tumor of left lung was diagnosed in 9 cases and tumor of the mediastinum--in 2 cases. Prosthetics of the arch of aorta was performed under condition of artificial circulation in 6 cases.
