Conclusion: In this patient, low dose regional anesthesia can be used as an alternative to anesthesia in patients with aortic stenosis because of the stable hemodynamic compared to conventional regional anesthesia. }, issn = {2089-970X}, doi = {10.14710/jai.v0i0.63167}, url = {https://ejournal.undip.ac.id/index.php/janesti/article/view/63167} }
