The　intra-aortic　balloon　pump　(IABP)　is　a　widely-used　mechanical　circulatory　support　device　that　enhances　hemodynamics　in　patients　with　heart　conditions.　Although　the　IABP　is　a　common　clinical　tool,　its　effectiveness　in　enhancing　outcomes　for　patients　with　acute　myocardial　infarction　and　cardiogenic　shock　remains　disputed.　This　study　aimed　to　assess　the　effectiveness　of　intra-aortic　dual-balloon　pump　(IADBP)　and　its　impact　on　aortic　hemodynamics　compared　with　an　IABP.　Three-dimensional　finite　element　models　were　constructed　for　the　aorta,　IABP,　and　IADBP,　followed　by　numerical　simulation　using　the　fluid-structure　coupling　(FSI)　method.　Three　simulations　were　conducted:　Heart　failure　patients　without　assistive　devices　(Case　A),　those　with　IABP　(Case　B),　and　those　with　IADBP　(Case　C).　The　study　assessed　the　IADBP＇s　hemodynamic　effects　by　measuring　aortic　branch　blood　flow,　left　ventricular　afterload,　aortic　wall　stress,　and　wall　shear　stress.　IADBP　outperformed　IABP　in　enhancing　blood　flow　to　the　coronary　arteries,　upper　limbs,　and　brain　vessels　(left　and　right　coronary　arteries:　0.88　vs.　1.27,　1.27　vs.　1.99　mL/beat;　brachiocephalic　artery,　left　common　carotid　artery,　and　left　subclavian　artery:　6.08　vs.　12.39,　2.48　vs.　4.97,　2.31　vs.　5.08　mL/beat).　IADBP　also　demonstrated　superior　performance　in　counterpulsation　pressure　and　left　ventricular　ejection　(counterpulsation　phase:　97.41　mmHg　vs.　110.03　mmHg;　ventricular　unloading　phase:　72.21　mmHg　vs.　66.46　mmHg).　The　use　of　IADBP　elevates　stress　on　the　aortic　wall　and　wall　shear　stress,　potentially　affecting　vascular　health.　IADBP　effectively　addresses　upper　limb　and　cerebral　hypoperfusion　issues　associated　with　IABP,　demonstrating　superior　performance　in　enhancing　counterpulsation　pressure　and　left　ventricular　ejection.　Despite　potential　vascular　biomechanical　effects,　IADBP　provide　a　promising　clinical　treatment　option.　Further　studies　are　needed　to　refine　IADBP　＇s　design　and　evaluate　its　long-term　clinical　efficacy.
