Predictors of Mid-Term AVNeo Insufficiency.

Introduction: Aortic stenosis (AS) is the most common valvular heart disease and the most common indication for aortic valve replacement in adults. Aortic valve neocuspidization (AVNeo) with fixed autologous pericardium, also known as the Ozaki procedure, is a possible alternative treatment of AS. Autopericardial valves save the dynamics and physiological anatomy of the aortic root, however, the service life of autopericardial leaflets is limited.

[Effect of the degree of stenosis of the right coronary artery on remote results of bypass grafting].

Aim: The purpose of this study was to assess the long-term results of right coronary artery bypass grafting and identify predictors of coronary artery bypass graft occlusion.

Patients And Methods: Our retrospective single-centre study included a total of 245 patients subjected to isolated coronary artery bypass graft operations during the follow up period from 2010 to 2015. All patients endured bypass grafting of the right coronary artery (RCA) with either autovenous or autoarterial conduits.

Coronary-coronary bypass grafting: artery or vein?

Background: The method of coronary-coronary bypass grafting was described in 1987 but has not been widely used, and there are only a few studies that report good short-term and mid-term results as well as some individual cases of long-term follow-up. In our medical institution, we carried out an analysis of the long-term results of coronary-coronary bypass grafting, which are presented in this study.

Methods: This was a retrospective single-center study on 95 patients who underwent coronary-coronary bypass grafting as a supplement to the standard coronary bypass grafting procedure.

[Retrograde type A aortic dissection after endovascular repair of the thoracic artery].

Retrograde type A aortic dissection is a severe and prognostically unfavourable complication of endovascular repair of the thoracic aorta. The aim of the present article is to describe a clinical case report concerning a hybrid operative intervention for retrograde type A aortic dissection in a patient having endured two-stage endovascular repair of the thoracic artery.

Pediatric cardiac surgery in Northern Russia. Results from an international cooperative program.

Objectives: In order to evaluate a Norwegian-Russian clinical cooperation, this study sought to compare the incidence, early mortality and morbidity of surgically treated patients with atrial septum defect (ASD), ventricular septum defect (VSD) and Tetralogy of Fallot (TOF) in Norway and Archangels region in Russia.

Design: A retrospective analysis of patient records of all those surgically treated for ASD, VSD and TOF in Norway and from Archangels region from 1 January 2000 to 31 December 2005.

Results: The Norwegian cohort consisted of 191 ASDs, 227 VSDs and 126 TOFs.
