With the limited knowledge of this case I would strongly disagree with this sentiment.
The language they used "multi-organ system failure, endocarditis, dilated cardiomyopathy with a low ejection fraction" is the type that sounds really scary to someone without medical training (Brent) but this line can be used on probably 20-30 patients in an average tertiary care facility at any point. Most of these people are walking out of the hospital at some point.
I believe you are a physician on the older side (correct me if I am wrong). Just wondering, but do you do a lot of inpatient ICU work or consultations? We do a much better job than 10, 20 years ago. Granted, I work in Cleveland so our ICU care and cardiology care is probably better than average. Reading between the lines, this sounds like it could be a case of acute cholecystitis which was missed, treatment was delayed, and he eventually went septic. When you catch this early, people do well. At my institution, we see plenty of cases (of all sorts) that have had delayed treatment, or wrong diagnosis, and we have to play catch up. Most of the time, we can.
Unless more information comes out, this just screams to me to be a case where warning signs were ignored. If this patient got timely treatment, I bet even the "ICU at the Mayo Clinic" could handle this one.
