Surgical Resection of the Greater Splanchnic Nerve in Subjects Having Heart Failure With Preserved Ejection Fraction

"Video-Assisted Thoracoscopic Surgery (VATS) is performed under general anesthesia using existing, CE marked instrumentation. Two or more 5 mm incisions are used to pass a tiny video camera and a single dissecting instrument into the chest. These small ports are advantageous because the chance for infection and wound dehiscence are drastically reduced. This allows for a faster recovery by the patient and a greater chance for the wound to heal.~In the procedure the GSN will be identified visually or through stimulation-induced hemodynamic reflex. The GSN will then be ablated using standard techniques. If there are multiple branches of the GSN, each branch will be systematically identified and ablated."
