Minimally invasive mitral valve repair in a patient with severe pectus excavatum: a case report

Pectus excavatum presents challenges in cardiac operations due to anatomical abnormalities and limited exposure. We report a case of a 58-year-old male with severe pectus excavatum and significant mitral regurgitation successfully treated with minimally invasive mitral valve repair. Preoperative imaging revealed leftward heart displacement and a Haller index of 3.8. Surgical intervention involved adaptations in atrial retraction and valve repair technique. Postoperative outcomes were favourable, with normal mitral function and a short hospital stay. Despite technical challenges, minimally invasive approaches offer benefits in pectus excavatum patients. This case underscores the feasibility and safety of minimally invasive surgery in patients with extensive pectus excavatum, emphasizing its potential as a preferred approach.
