We thank you for your interest in our study. We agree that patients with a blowout type of rupture tended to have a higher in-hospital mortality rate compared to oozing type. Our registry previously reported similar results that blowout type of rupture was associated with a higher risk of in-hospital death [1]. Regarding the possibility to make an association between the type of rupture and the AMI-to-cardiac rupture time, blowout rupture can occur 48 h after the onset of AMI. Therefore, we believe that the blowout rupture is not reasonable based on AMI-to-cardiac rupture time < 24 h only. We agree with your point about the use of mechanical support, such as intra-aortic balloon pumps and external life support, being an important issue to consider because of potential positive impact. Our registry data similarly showed a positive trend for mechanical support on survival [1]. Funding None.
