    Surgical approach to combined mitral and tricuspid valve disease: good neighbourhood rules
  2. 222
    “…Certainly, making this procedure less extensive and limiting the ablation in the right atrium (avoiding the potential complications of a left atrial approach) and at level of anatomical regions of the most important ganglionated plexy, considered ‘gateway’ of the sino-atrial and atrio-ventricular node function (through the recognition of specific endocardial potentials), could be very advantageous in this clinical scenario. …”
