We report the first successful implantation of a HeartMate 3 (HM3) left ventricular assist device (LVAD) in Vietnam, marking a critical milestone in the country\u2019s cardiovascular surgery. The patient, a 46-year-old female with stage D heart failure (NYHA class IIIB, INTERMACS profile 4) secondary to dilated cardiomyopathy, presented with dual anatomical constraints. Preoperative imaging revealed a technically challenging, small, and spherical left ventricle (long-axis: 52\u2009mm). Furthermore, thoracic anthropometry demonstrated a distinct oval-shaped chest morphology common in Asian populations, with a low Thoracic Index of 0.67 (AP diameter 206.1\u2009mm; transverse diameter 305.6\u2009mm), significantly restricting the retrosternal space for device housing. Despite these constraints, the HM3 was successfully implanted through a full sternotomy, with meticulous attention to inflow cannula angulation. At the 6-month follow-up, the patient exhibited dramatic functional recovery (NYHA class I). Her Kansas City Cardiomyopathy Questionnaire (KCCQ-12) score surged from 51.04 to 91.67, and the 6-min walking distance improved from 315 to 450\u2009m, without any device-related adverse events. This case confirms the feasibility of the HM3 in restricted anatomical settings and underscores the importance of considering race-specific thoracic morphology in the planning of advanced mechanical circulatory support.<\/jats:p>","DOI":"10.1177\/03913988261469886","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T05:02:31Z","timestamp":1785474151000},"page":"828-833","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["First successful HeartMate 3 in Vietnam: Anatomical challenges of a small, spherical ventricle, and an oval-shaped thoracic morphology"],"prefix":"10.1177","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1268-860X","authenticated-orcid":false,"given":"Thai Quang","family":"Tran","sequence":"first","affiliation":[{"name":"Military Central Hospital 108, Hanoi, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anh Tuan","family":"Ngo","sequence":"additional","affiliation":[{"name":"Military Central Hospital 108, Hanoi, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hung Quoc","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Military Central Hospital 108, Hanoi, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duc Viet","family":"Dang","sequence":"additional","affiliation":[{"name":"Military Central Hospital 108, Hanoi, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giang Thai","family":"Pham","sequence":"additional","affiliation":[{"name":"Military Central Hospital 108, Hanoi, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Song Huu","family":"Le","sequence":"additional","affiliation":[{"name":"Military Central Hospital 108, Hanoi, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai Doan Duy","family":"Tran","sequence":"additional","affiliation":[{"name":"Universit\u00e4tsmedizin G\u00f6ttingen, G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan D","family":"Schmitto","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Transplantation and Vascular Surgery, Hannover Medical School, Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,7,30]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/ejhf.1858"},{"issue":"18","key":"e_1_3_3_3_2","article-title":"2022 AHA\/ACC\/HFSA guideline for the management of heart failure","volume":"145","author":"Heidenreich PA","year":"2022","unstructured":"Heidenreich PA, Bozkurt B, Aguilar D, et al. 2022 AHA\/ACC\/HFSA guideline for the management of heart failure.
