I can understand where you are coming from, but frankly, unless you personally know Dan, or are telepathic, how can you possibly know his motives for writing his post. Your accusation is one possibility, as is also the motive of trying to inform prospective ablation patients. I dont know him and have not read his book, but i wouldnt slur him by attributing greed as the drive behind his contribution. After what happened to his wife, maybe he is just trying to help others.
Gathering as much info as poss, inc a wide source of expert opinions, before having any operation/procedure with risks attached, is surely a wise thing to do. To dismiss someone's work without reading it because it feels scary is hardly objective. Sometimes the truth is scary. And doctors themselves ( well intentioned ) often use scare tactics to influence a patients decision.
I would never discourage anyone from having an ablation, but neither would i encourage anyone to go ahead. Encouragement should be toward the patient becoming as well informed as poss as to the risks and outcome, so as to enable them to feel as confident as poss when deciding if it is right for them.
Thru searching over 2 years and spending many hours on medical sites as well as attending several conferences at Birmingham, and having the opportunity to speak privately with cardiologists and EPs, i realised the info/advice i had received from my consultant was selective and i was not given the full picture. Reading posts on forums around the world I suspect others have experienced the same.
