Best Hospitals in United States for Cardiac Surgery: A Data-Based Review of National Rankings

The best hospitals in United States for cardiac surgery are identified through several national evaluations that consider outcomes, clinical expertise, patient experience, and hospital capabilities. Recent U.S. News reporting placed NYU Langone Hospitals first for cardiology, heart and vascular surgery, while Newsweek’s specialized cardiac-care ranking placed Mayo Clinic Rochester first, illustrating why patients should examine methodology rather than rely on a single list.13

How national cardiac rankings are constructed

U.S. News evaluated nearly 500 heart hospitals for its 2026-2027 cardiology, heart and vascular surgery ranking. Eligibility involved minimum procedure volumes and a transfer-pattern review intended to identify major referral centers, reducing an initial group of 665 hospitals to 488 eligible institutions.1 The evaluation covered abdominal aortic aneurysm repair, aortic valve surgery, arrhythmia, coronary artery bypass surgery, heart attack, heart failure, pacemaker implantation, and transcatheter aortic valve replacement.

Survival accounted for 45 percent of the U.S. News score, with the remaining score divided among discharge-to-home rates, readmission prevention, and patient experience.1 Another report described a newer methodology in which 41 risk-adjusted patient outcomes represented 80 percent of the score, compared with 45 percent previously.2 Differences in publication timing and methodology mean rankings should be read as comparative indicators, not guarantees of an individual surgical result.

Leading hospitals in the U.S. News results

The reported U.S. News list identifies the following leading hospitals and scores out of 100. The ranking is for cardiology, heart and vascular surgery collectively, so it includes catheter-based care and medical management as well as open cardiac operations.1

What cardiac surgery programs commonly provide

Leading academic heart centers generally organize care around several major surgical categories. Cleveland Clinic lists coronary artery bypass grafting, valve surgery, aortic surgery, and minimally invasive procedures among its adult cardiac services.4 Mayo Clinic describes cardiovascular surgery involving coronary arteries, heart valves, the aorta, and heart failure, while Massachusetts General Hospital reports services for coronary, valvular, aortic, and adult congenital heart disease.56

NewYork-Presbyterian identifies bypass, valve repair and replacement, aortic surgery, and minimally invasive cardiac procedures as part of its program.7 Cedars-Sinai and Stanford also describe care for coronary disease, valve disorders, aortic conditions, and complex or minimally invasive operations.89 The relevant question is therefore not simply which hospital ranks highest, but whether the center has experience with the specific procedure, anatomy, risk profile, and urgency involved.

Outcome evidence from a high-volume center

Cleveland Clinic published selected 2025 adult cardiac surgery volumes and observed operative mortality alongside Society of Thoracic Surgeons expected mortality. Isolated CABG involved 969 cases, with 0.8 percent observed mortality versus 1.6 percent expected mortality; isolated aortic valve replacement involved 408 cases, with 0.0 percent observed mortality versus 1.6 percent expected mortality.10

For combined aortic valve replacement and CABG, Cleveland Clinic reported 213 cases and 1.9 percent observed mortality versus 3.4 percent expected. Isolated mitral valve replacement involved 167 cases, with 2.4 percent observed mortality versus 4.7 percent expected, while 447 isolated mitral valve repairs had 0.0 percent observed mortality versus 0.7 percent expected.10 These figures describe one institution and selected procedures, and they should not be generalized to every operation or every patient.

Why different rankings produce different leaders

Newsweek’s America’s Best Hospitals for Specialized Care 2026 ranked Mayo Clinic Rochester first in cardiac care, followed by Massachusetts General Hospital, Cleveland Clinic, NYU Langone Hospital Tisch, and Johns Hopkins Hospital.3 Its listed standout specialties included CABG, coronary angioplasty and stent placement, coronary artery disease, heart valve surgery, and heart transplant. The ranking was based on clinical performance, patient outcomes, expert input, and patient-reported outcome measures.

The Premier and Modern Healthcare 50 Top Cardiovascular Hospitals program used an objective quantitative analysis of publicly available data and compared recognized hospitals with peer institutions across 21 measures, including clinical outcomes, operational efficiency, extended outcomes, and patient experience.5 Its reported national observations included a 56 percent difference in CABG inpatient-mortality index between benchmark and peer hospitals. Because the program measures broader cardiovascular performance, it is not identical to a ranking of complex cardiac surgery alone.

Clinical, regulatory, and practical limits

Hospital rankings cannot eliminate the risks associated with cardiac surgery. Outcomes vary according to age, comorbidities, emergency status, prior operations, disease complexity, and the procedure selected. A high position may reflect broad cardiovascular performance rather than a center’s results for one narrowly defined operation. Patients and referring clinicians must also consider travel, continuity of follow-up, rehabilitation arrangements, insurance network rules, and transfer logistics.

External oversight and public reporting provide additional context. The Society of Thoracic Surgeons maintains a public reporting platform for participating cardiac surgery programs, allowing performance information to be reviewed beyond consumer rankings.11 However, participation and available measures may differ among hospitals. Questions about surgeon-specific volume, program-level complications, expected versus observed mortality, accreditation, and the availability of multidisciplinary review are more informative than a ranking number alone.

Interpreting the evidence for a surgical decision

The strongest comparison combines several forms of evidence: a hospital’s position in a recognized ranking, risk-adjusted outcomes for the proposed operation, procedure volume, the surgical team’s expertise, and the hospital’s capacity for intensive care and complex rescue treatment. For valve, aortic, transplant, congenital, or repeat operations, disease-specific experience may be more relevant than an overall cardiology score.

National lists offer a starting framework, not a clinical recommendation. U.S. News, Newsweek, Premier, hospital disclosures, and STS reporting measure overlapping but distinct aspects of care.13511 A careful review should distinguish open surgery from catheter-based treatment, elective from emergency cases, and hospital-wide reputation from procedure-level outcomes. Final decisions require individualized assessment by qualified cardiac specialists.
