The Cleveland Clinic and Boston Children’s Hospital are the top-ranked hospitals in the U.S. for adult and children cardiology and heart surgery, according to the U.S. News & World Report's best hospital rankings released on July 21.

For the 26^th edition of its rankings, U.S. News ranked hospitals on a 0 to 100 scale based on four elements: reputation with specialists (accounted for 27.5 percent of the score); survival (32.5 percent); patient safety (10 percent); and other care-related indicators such as nurse staffing, patient volume and clinically-proven technologies (30 percent).

Hospitals were considered only if they were nonfederal community facilities and met any of the four following criteria: teaching-hospital status; medical school affiliation; 200 or more beds set up and staffed; or 100 or more beds set up and staffed plus availability of at least four medical technologies that U.S. News considered important for high-quality care.

The top 10 hospitals for adult cardiology and heart surgery were:

1. Cleveland Clinic in Cleveland, Ohio (score of 100)
