Researchers recommend that healthcare providers incorporate messages for both breast health and heart disease prevention to maximize impact.
A study of over 1,100 patients who underwent mitral valve repair found that older age and preoperative atrial fibrillation significantly increased the risk of developing tricuspid regurgitation. The risk was further exacerbated by impaired heart function, with patients experiencing devastating effects from severe TR.
