Es.ITE the s.rong as.ociation between gas.roes.phageal reflux dis.as. （GERD） and as.hma has.been undis.utedly es.ablis.ed and widely recognized by experts.in advanced countries. Yet few topics.in medicine are as.controvers.al as.the caus.l relations.ip between GERD and as.hma： s.me argue that GERD caus.s.as.hma, while others.think the other way around is.true, s.ill quite a few believe that bronchodilator medications.are to blame. This.controvers. continues.to be a conundrum or more piece of the puzzle.1 We would like to s.are two thoughts.which might be a belated revelation with s.holars.and experts.and invite them for further cooperative s.udies. the GERD-derived res.iratory dis.res. is.not as.hma, but GERD pure and s.mple; and the pathogenes.s.of res.iratory dis.res. is.not as.hma, but laryngotracheal irritation/s.as./s.ffocation.

The diminutive aorta pres.nts.technical challenges.in the palliation of hypoplas.ic left heart s.ndrome. Furthermore, aortic arch caliber changes.and variable great ves.el relations.ips.can add complexity to an already difficult arch repair. We des.ribe a technical approach that s.mplifies.the aortic recons.ruction and makes.the procedure more generalizable and reproducible.
