I'm very sorry to hear this. Have you contacted his breeder to let them know? If they were reputable, I'm sure they will want to know for their records and to let the owners of Bentley's littermates know.

Did they say what disease it was? Was it Sub Aortic Stenosis or Cardiomyopathy?

I'm very sorry that you have to worry about this right now, I hope that you have many many years with your boy.
