Effectiveness of Artificial Neochordae Implantation in Tricuspid Valve Repair.

Various techniques for treating tricuspid regurgitation have been described; however, because of scarce data about the long-term outcomes of different repairs, the optimal technique has not been established. We evaluated the effectiveness and durability of artificial neochordae implantation in the treatment of tricuspid regurgitation. From 2009 through 2014, 507 patients underwent tricuspid valve repair at our institution.

Left atrial strain in heart failure with preserved ejection fraction.

Background: Heart failure with preserved ejection fraction (HFpEF) is a syndrome in which patients have symptoms and signs of heart failure but preserved ejection fraction. Left atrial (LA) volume and function are known to be impaired in these patients. Two-dimensional speckle-tracking echocardiography (2D-STE) has recently enabled the quantification of LA deformation dynamics.

[Comparison of controlled pressure belt -allowing mobility to sandbags after percutaneous coronary intervention: pilot study].

Objectives: We aimed to investigate the efficacy and safety of a belt mechanism (anjiobelt), which we developed recently and patented, which allows mobility after coronary operations and the application of adjustable pressure to the femoral artery.

Study Design: Between October 2012 and April 2013, 189 consecutive patients undergoing percutaneous coronary intervention electively or due to acute coronary syndrome were enrolled. There were 96 patients in the sandbag group and 93 patients in anjiobelt group.
