We discuss a case of a patient who was referred to our department for an in-depth evaluation of aortic regurgitation severity and its underlying causes. By employing a multimodal imaging strategy that combined transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and cardiac magnetic resonance imaging (cMRI), we successfully identified a particularly rare cause of aortic regurgitation: chordae tendineae that lead to asymmetric retraction of the aortic cusps. Furthermore, this approach provided a clearer understanding of the aortic root anatomy and the hemodynamic effects of the regurgitant flow on the ventricle. This case demonstrates the diagnostic effectiveness of various imaging techniques and emphasizes the crucial importance of multimodal imaging for a thorough assessment of aortic valvular issues.

Cardiovascular magnetic resonance (CMR) imaging is a key component of current diagnostic pathways in subjects with acute myocarditis. The 2020 ESC Guidelines on Sports Cardiology recommend athletes with acute myocarditis to abstain from sports during the recovery phase from inflammation and to undergo comprehensive evaluation—including CMR—before safely returning to play. This retrospective study analyzed 95 non-competitive athletes presenting with acute myocarditis and evaluated by initial and repeated CMRs. CMR exams assessed myocardial inflammation, edema, and scarring as defined based on the updated Lake Louise criteria. As per 2020 ESC Guidelines, eligibility was granted by excluding extensive myocardial damage. Initial CMR showed 84% positive STIR (edema) and 79% with LGE ≥ 3 segments. After 3–6 months, STIR positivity dropped to 12%, LGE extent remained globally stable, but with some reduction in 42%. Few experienced recurrent myocarditis or LVEF decline; 24% met return-to-play criteria by repeated CMR. Our study shows that few non-competitive athletes recovering from acute myocarditis meet ESC CMR criteria to resume competitive sports at prescribed follow-up evaluation. The long-term prognostic value of CMR markers like LGE and edema remains unclear, highlighting the need for further research to refine return-to-play guidelines and ensure athlete safety.
