In older adults, bioprosthetic valves rarely fail within 5 years of the index surgery. Such failures pose a challenge to patients, clinicians, and surgeons. Although clinicians are generally aware of valve dysfunction related to overt endocarditis, patient–prosthesis mismatch, and technical error, less-recognized causes of early bioprosthetic valve failure include valve thrombosis (Figures 1 and 2⇓⇓, Online Videos 1 and 2), excessive pannus formation (Figures 3 and 4⇓⇓, Online Videos 3, 4, 5, and 6), and accelerated structural valve deterioration (Figures 5 and 6⇓⇓, Online Videos 7, 8, 9, and 10). Given their rarity, these failure mechanisms have not been well characterized, and echocardiographic features that may aid in diagnosis are sparse. In this pictorial essay, we highlight these lesser-known causes of early bioprosthetic valve failure. By recognizing simple echocardiographic findings within a clinical context, the correct diagnosis for these infrequent presentations can be ascertained (Figure 7).
