Analgesia in Patients Undergoing Transfemoral Transcatheter Aortic Valve Implantation (TF-TAVI)

Ilioinguinal and iliohypogastric (ILIH) nerve blocks are frequently performed for analgesia in inguinal surgery. The investigators hypothesized that preoperative ultrasound-guided ilioinguinal and iliohypogastric (ILIH) nerve blocks will produce better intraoperative analgesia and less analgesic requirement postoperatively in comparison to commonly used preoperative local infiltration anaesthesia for patients undergoing transfemoral transcatheter aortic valve implantation (TF-TAVI).
