The most likely match is Charles Roy “Chuck” Snider Jr. , and the obituary says he had congestive heart failure for about 10 years before he died during an LVAD repair surgery. If you meant a different Charlie Snider, the illness may be different, because several unrelated people with similar names showed up in the search results.

What was reported

Why there may be confusion
