Key result

Multimodality imaging and Heart Team evaluation successfully guide surgical replacement for fibrous pannus.

Why the study?

Accurate identification of the underlying etiology of mechanical valve dysfunction is essential because management differs substantially between thrombotic and non-thrombotic causes.

Implication

Supports guideline-directed multimodality imaging and Heart Team evaluation in prosthetic valve dysfunction; leaves open need for prospective validation.

Key Points

To evaluate the role of multimodality imaging and multidisciplinary Heart Team decision-making in diagnosing and managing mechanical mitral prosthesis dysfunction.
Evaluated a 60-year-old male with exertional dyspnea after previous mechanical mitral valve replacement and tricuspid annuloplasty.
Conducted sequential transthoracic echocardiography, transesophageal echocardiography, and contrast-enhanced chest computed tomography before surgical exploration.
Echocardiography revealed restricted leaflet motion and an elevated mean transprosthetic gradient of 21 mmHg, while contrast CT ruled out valve thrombosis.
Surgical intervention confirmed fibrous pannus and annular calcification, resulting in successful re-replacement with a bioprosthesis and normalization of transprosthetic gradients.

Population

A 60-year-old man with mechanical mitral prosthesis dysfunction who presented with progressive exertional dyspnea and a high transprosthetic gradient.

Intervention

Multimodality imaging (transthoracic echocardiography, transesophageal echocardiography, contrast-enhanced chest computed tomography) and surgical replacement with a 29-mm bioprosthesis.

Outcome

Postoperative recovery, normalization of transprosthetic gradients, and improvement in functional status.

This case highlights the critical role of multimodality imaging and Heart Team discussion in differentiating pannus from thrombosis to guide appropriate surgical management of mechanical valve dysfunction.

Cite This Study

Maltempi et al. (2026) conducted a case report in Mechanical mitral prosthesis dysfunction (n=1). Multimodality imaging and Heart Team decision-making was evaluated. Multimodality imaging and Heart Team evaluation successfully identified fibrous pannus causing a high transprosthetic gradient (21 mmHg) in a 60-year-old man, guiding successful surgical replacement.
