Does moderate tricuspid regurgitation require attention during mitral valve surgery?
Preoperative TR ≥ 2+, non-TVR group had more favourable functional class and mid-term survival with comparable QOL and echocardiographic parameters to the TVR group.
Exposure to hyperkalemia reduces the indomethacin- and L-NNA-resistant, endothelium-dependent (endothelium-derived hyperpolarizing factor-related) relaxation in the human coronary artery. This suggests that the previously proposed mechanism of coronary dysfunction after exposure to cardioplegic and organ preservation solutions in animal vessels is also valid in the human heart.
