Hangzhou, China · HCM surgery through an underarm incision, with the breastbone preserved

Research by Yevhenii Kozlov · Co-Founder of BookimedUpdated 8 October 2026Sources linked throughout

At a glance

The Hangzhou team has published operations that relieve obstructive HCM through an incision near the right armpit. Its newer 100-patient MESM study reports early relief of obstruction while preserving the breastbone. An earlier study also treated abnormal mitral-valve supports that contributed to the blockage.

Relief of outflow obstruction

In the 100-patient MESM study, the mean pressure gradient across the narrowed outflow fell from 85.8 to 8.4 mmHg. These were early postoperative results.

4–5 cm incision; breastbone intact

The study used an incision near the right armpit. No patient in that series required conversion to sternotomy.

Clinical benefits and limitations

Potential advantages

Preserving the breastbone removes a major recovery burden: healing a surgically divided sternum. Daily movement can focus on comfort, the chest-wall wound and gradually rebuilding activity.

Trade-offs and limits

In the 100-patient MESM series, four patients required a permanent pacemaker and no in-hospital deaths were observed. This selected, single-centre study reports early outcomes without a matched sternotomy group; zero observed deaths does not mean zero risk.

Right infra-axillary transaortic myectomy with documented subvalvular work.

148 patients. 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. Numerical follow-up duration was not specified in the inspected report.

How to interpret this: Cui is senior/corresponding author; the full paper does not explicitly assign all operations to him personally. 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. 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. Early postoperative outcomes; long-term duration unavailable in the abstract.

How to interpret this: Cui is senior/corresponding author and the practice site’s technique proponent. Personal operator count is not established by the abstract. 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.
