Despite its frequency, it remains underrecognized in sports cardiology. PE results from sternal depression and narrowing of the anterior chest, which may lead to cardiac compression, impaired diastolic filling, and reduced stroke volume during exercise. Consequently, athletes with PE often present with cardiovascular symptoms such as exercise-induced dyspnoea, chest pain, palpitations, presyncope, or reduced physical fitness. Electrocardiographic changes, including right bundle branch block, axis deviation, atrial enlargement, T-wave inversion, QS complexes or Brugada phenocopies, are frequent and may mimic serious cardiovascular conditions, complicating pre-participation screening. Furthermore, PE is associated with potentially high-risk conditions including mitral valve prolapse, ventricular arrhythmias, and connective tissue disorders such as Marfan syndrome, which carry implications for sports eligibility and safety. Assessment of athletes with PE requires multimodal imaging (echocardiography, computed tomography, magnetic resonance), cardiopulmonary exercise testing, and exclusion of concomitant cardiovascular disease. Treatment strategies range from conservative approaches (physiotherapy, vacuum bell therapy) to surgical correction, most commonly with the Nuss procedure, which can improve cardiac function, exercise capacity, and quality of life. Management should involve shared decision making between clinicians, athletes, and families, weighing potential risks against athletic aspirations. Awareness of PE in sports cardiology is crucial, as it not only influences differential diagnosis and screening outcomes but also impacts career decisions and the psychological well-being of athletes.<\/jats:p>","DOI":"10.3390\/diagnostics15232956","type":"journal-article","created":{"date-parts":[[2025,11,21]],"date-time":"2025-11-21T15:33:06Z","timestamp":1763739186000},"page":"2956","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Pectus Excavatum\u2014A Frequent but Often Neglected Entity in Sports Cardiology"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9586-0163","authenticated-orcid":false,"given":"\u0141ukasz","family":"Ma\u0142ek","sequence":"first","affiliation":[{"name":"Department of Nursing, Faculty of Rehabilitation, University of Physical Education in Warsaw, 00-968 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3207-1248","authenticated-orcid":false,"given":"Anna","family":"Lema\u0144ska","sequence":"additional","affiliation":[{"name":"Central Clinical Hospital, Medical University of Warsaw, 02-507 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2393-4194","authenticated-orcid":false,"given":"Mateusz","family":"\u015apiewak","sequence":"additional","affiliation":[{"name":"Magnetic Resonance Unit, Department of Radiology, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"ezae166","DOI":"10.1093\/ejcts\/ezae166","article-title":"The pectus care guidelines: Best practice consensus guidelines from the joint specialist societies SCTS\/MF\/CWIG\/BOA\/BAPS for the treatment of patients with pectus abnormalities","volume":"66","author":"Dunning","year":"2024","journal-title":"Eur.
