Confirmed Institutional Context
- Dr. John L. Petersen worked at both Swedish and Virginia Mason during the same time period.
- Dr. Petersen’s father appears to have worked at Swedish previously.
- Dr. Petersen’s name, or his father’s name, appears on a Swedish donor list.
Leonardo C. Mariano v. Swedish Cardiac Surgery
- Court: Washington Court of Appeals, Division I
- Docket Number: 68924-0-I
- Original Filing Date: May 2, 2011
- Appeals Decision Date: November 25, 2013
- Supreme Court Review: Petition for Review denied in 2014 (Case No. 90011-6)
I reviewed this case because it involved Swedish cardiac surgery and informed consent issues. Based on the court record, the plaintiff alleged that bypass surgery was unnecessary and that proper informed consent had not been obtained.
The case was dismissed because the plaintiff did not provide the expert testimony required to prove negligence in a complex medical case.
Similar-Name Court Record
I also found a court record involving a John Peterson / similar spelling in connection with another angiogram-related injury.
Because the spelling is different, I cannot independently confirm that it is the same person. I am noting it because of the similarity in name and subject matter.
Why These Public Records Matter to Me
These public records matter to me because they provide context for why complete records, expert review, and clear procedural documentation are important in cases involving cardiac procedures and patient injury.
