Looking for an oncologist's second opinion on Uchenna's a congenital heart murmur

Uchenna was diagnosed with a congenital heart murmur in June. The local team has recommended a major procedure. We understand it's an important decision, and we'd like to be sure. We're asking if an oncologist - anywhere in the world - would be willing to review Uchenna'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. Even a small gift gets used right away and I'll thank you myself.
