Looking for a rheumatologist's second opinion on Joshua's a congenital heart murmur

Joshua was diagnosed with a congenital heart murmur in November. The local team has recommended a long course of medication. We understand it's an important decision, and we'd like to be sure. We're asking if a rheumatologist - anywhere in the world - would be willing to review Joshua's reports and give a short opinion (a call of 20 minutes or a written summary). We'd gladly pay for any cost to your practice that we can afford. We have scans, lab reports and the doctor's notes ready to share securely. We understand that you can't give formal medical advice without an examination, and we're simply looking for guidance on questions to ask and options to explore. Thanks for even thinking about it. Whatever you can give, even just sharing this page, means a lot.
