Methods: A 62-year-old female developed a giant LV pseudoaneurysm one year after initial surgical repair of a free wall rupture with a xenopericardial patch. Imaging confirmed a large pseudoaneurysm with a broad neck and mural thrombus. She underwent pseudoaneurysmectomy, LV reconstruction with a Dacron patch overlaid by a xenopericardial patch, and concomitant mitral and tricuspid valve repair. Results: Surgical exploration revealed a broad-necked pseudoaneurysm and dehisced patch material. The aneurysm was resected, and the LV was reconstructed, resulting in the exclusion of the pseudoaneurysm and improvement of the shape and function. The patient recovered uneventfully and was discharged in good clinical condition with restored LV function. Conclusions: Pseudoaneurysm formation after LV free wall rupture repair is often due to insufficient resection and the use of only a xenopericardial patch. Surgical management with complete excision, Dacron patch reconstruction, and xenopericardial reinforcement facilitates the favorable remodeling of LV geometry and function, and reduces the risk of recurrence.<\/jats:p>","DOI":"10.3390\/jcm14103393","type":"journal-article","created":{"date-parts":[[2025,5,13]],"date-time":"2025-05-13T06:40:23Z","timestamp":1747118423000},"page":"3393","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Pseudoaneurysmectomy After Left Ventricular Free Wall Rupture Repair: A Case Report"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3083-6882","authenticated-orcid":false,"given":"B.
