HCM and septal myectomy surgeons and specialist teams
Compare reported surgical experience
Positions use published operation counts within the same procedure, reporting period and attribution. “+” is a reported minimum. Personal operations, participation and programme totals have separate lists. A dash means open-ended counts do not establish an exact place. The lists compare experience, not safety or suitability.

Right infra-axillary modified-Morrow myectomies. This technique-specific count is a minimum for the programme’s total myectomy activity; other approaches are not included.
Right infra-axillary transaortic myectomy with documented subvalvular work.
148 patients in this study
September 2021–July 2023 · published 2024
Papillary resection in 72/148 (48.6%); chordal resection in 93/148 (62.8%); papillary reorientation in 15/148 (10.1%). Procedures overlap.
Results: Mean peak LVOT gradient 85.1 → 11.7 mmHg after surgery. 1/148 in-hospital death; 8/148 permanent pacemakers; no conversion to sternotomy reported.
Follow-up: Numerical follow-up duration was not specified in the inspected report.
Study context: Zhejiang Provincial People’s Hospital study, with Yong Cui as senior/corresponding author. Selected single-centre approach series without a sternotomy control group. Pacemaker risk is affected by baseline conduction abnormalities. This is the earlier modified-Morrow series, not the newer 100-patient MESM series.
Electro-septal sculpting through a 4–5 cm right infra-axillary incision.
100 patients in this study
November 2023–May 2024 · print publication 2026
A distinct newer technique cohort. The practice site describes a long electrocautery instrument; the study abstract reports aortic cross-clamping.
Results: Mean peak LVOT gradient 85.8 → 8.4 mmHg after surgery. 4/100 pacemakers; no in-hospital death, iatrogenic VSD or sternotomy conversion reported.
Follow-up: Early postoperative outcomes; long-term duration unavailable in the abstract.
Study context: Zhejiang Provincial People’s Hospital study, with Yong Cui as senior/corresponding author. Abstract-only review. Do not sum this cohort with other publications or the practice website’s lifetime claims. Zero observed deaths does not mean zero risk.
A broad surgical series that includes mitral and subvalvular correction.
522 operations combined myectomy with mitral or subvalvular intervention. Those patients had thinner septums on average than patients without mitral intervention.
Programme operations · 2002–2021; exact boundary dates not specified
Cleveland programme experience across 2002–2021, described by Milind Desai in an official clinical discussion. It is separate from Smedira’s personal participation count.

1530 myectomy-containing operations in this study
2005–2015 · study published 2019
522 operations combined myectomy with mitral or subvalvular intervention. Those patients had thinner septums on average than patients without mitral intervention.
Results: Operative mortality 0.38% in the full 1,559-operation LVOTO cohort. Complete-block pacemakers: 4.2% of the reported 1,334-patient denominator.
Follow-up: Perioperative outcomes in the primary abstract; no comparable long-term duration extracted.
Study context: Smedira is a currently listed myectomy specialist and study coauthor. The primary abstract says one surgeon, but does not name that operator. These are programme-study results. 1,530 is derived from 586 isolated + 522 with mitral/subvalvular work + 422 with other procedures. Another 29 operations were mitral-only. This is not current annual volume.
Daniel Swistel directs HCM surgery at NYU Langone. His published resect–plicate–release approach combines septal muscle removal with selected leaflet shortening and release of abnormal papillary attachments.
Explicitly attributed individual-operator experience with longer-term follow-up.
482 patients analysed; 507 operated in this study
2003–2016 · study published 2017
All 507 myectomies are attributed to Rastegar. The analysis excludes 25 patients with severe aortic stenosis.
Results: 4/482 operative deaths; 43/482 complete-heart-block pacemakers. The paper’s lower adjusted pacemaker percentage is not the all-patient rate.
Follow-up: Mean clinical follow-up 3.2 years. Estimated survival: 94% at 5 years and 91% at 10 years; not every patient was followed for 10 years.
Study context: Individual operator named in the primary study. Historical benchmark; current appointment and availability were not established in this review. Different selection and follow-up denominators apply. Older outcomes are useful for understanding durability, not a present-day booking recommendation.
Joseph Dearani’s Mayo practice spans HCM, Ebstein anomaly, congenital surgery and complex reoperations. Mayo’s selected apical-myectomy research addresses a different problem from routine basal septal obstruction.
Joshua Scheinerman is associate surgical director of NYU’s HCM programme. The hospital identifies him as a lead operator in its first reported robotic trans-mitral myectomy, performed through right-chest ports.
Myectomy plus cutting selected secondary mitral chordae
350 consecutive patients in the reported centre cohort in this study
Published June 2026 · operations over a five-year period
Addresses thickened or retracted secondary chordae alongside septal muscle.
Results: Follow-up available for 344 patients; latest NYHA classes I / II / III: 271 / 65 / 8. Reported six-year overall survival was 96%, including two in-hospital deaths.
Follow-up: Median 5.6 years (interquartile range 4.2–6.3).
Study context: Single-centre team cohort; Ferrazzi is first author. It is not his personal lifetime count. Observational series. Population-matched survival is not a comparison with other surgeons or methods. Primary abstract reviewed.
Transapical beating-heart myectomy: a different access route and instrument strategy.
418 patients in this study
January 2023–January 2024 · published 2025
The post-learning-curve series uses a transapical approach. It is distinct from Cui’s right infra-axillary, transaortic MESM.
Results: 91.1% met the defined 3–6-month composite: resting/provoked LVOT gradient below 30/50 mmHg and MR no worse than 2+. 1/418 died within 30 days; 10/418 needed pacemakers.
Follow-up: Median 310 days (IQR 207–408).
Study context: Team cohort with Xiang Wei as senior/corresponding author; the abstract does not establish that he operated on every patient. Primary abstract reviewed; detailed exclusions require full text. Also reported: 3 apical tears, 3 mitral injuries and 2 transient ischemic strokes. The 91.1% definition is not a general “success rate”.
Procedure-specific evidence makes differences in technique, anatomy and observation period visible before comparing teams.
Trade-offs and limits
These studies are not a matched comparison of the listed surgeons. Personal treatment suitability and risk require clinical assessment.
How to read the comparison
Recruitment dates describe when operations took place; follow-up describes how long patients were observed. Both remain visible beside each study.
Complication and outcome definitions differ. Counts are not pooled, programme cohorts are not automatically personal surgeon totals, and smaller incisions are not treated as proof of better outcomes.
