Background: Tricuspid valve repair for functional regurgitation is effectively performed with different annuloplasty devices. However, it remains unclear whether there are advantages associated with rigid rings compared to flexible bands. This prospective randomised study aimed to compare results of using a flexible band ring versus a rigid ring for functional tricuspid regurgitation in patients undergoing mitral valve surgery.

Objective: Left atrial size is critical to the success of concomitant atrial fibrillation (AF) ablation in patients scheduled for MV surgery. However, a large LA should not be a limiting factor when evaluating surgical candidates with AF if they receive appropriate treatment during concomitant ablation.
Background: Septal myectomy is the gold standard treatment for hypertrophic obstructive cardiomyopathy. This study aimed to evaluate the results from patients with hypertrophic cardiomyopathy who had undergone septal myectomy.
Methods: Data were analysed that has been prospectively collected over 7 years from 345 patients with hypertrophic cardiomyopathy who underwent septal myectomy at Meshalkin National Medical Research Center.
Objectives: To compare the outcomes of left atrial ablation and biatrial (BA) ablation in patients with persistent and long-standing persistent atrial fibrillation undergoing open heart surgery.
Methods: Between January 2007 and December 2016, 588 consecutive patients with either persistent (20.9%) or long-standing persistent atrial fibrillation (79.
