Transcatheter Valve

Bicuspid aortic valve (BAV) disease is the most common congenital abnormality and is characterized by a risk of premature aortic valve disease, predominantly aortic stenosis. Surgery remains the treatment of choice for patients with symptomatic BAV disease, but, in patients who are unsuitable for surgical aortic valve replacement, transcatheter aortic valve replacement (TAVR) is currently used as an alternative to surgery, although there is no official recommendation for their management, since BAV patients with severe aortic stenosis have been excluded from the major TAVR randomized clinical trials. Patients with BAV stenosis present anatomic challenges for treatment with TAVR. The BAV annulus often has an elliptical shape and is larger than the tricuspid valve, and is more likely to exhibit severe eccentric calcification. In addition, BAV is often associated with a dilated, horizontal ascending aorta, and effaced sinuses. The calcified raphe may also place differential stress on the expansion of the transcatheter valve, increasing the risk of suboptimal positioning and consequently the risk of paravalvular leakage, new pacemaker implantation, new-onset left bundle branch block, and annular rupture. Moreover, coronary obstruction may occur when leaflet fusion results in a longer leaflet. Although some of these challenges have been successfully overcome using new-generation devices, the complication rate is still relatively high and requires a deeper understanding of the patient’s specific complex and variable anatomy. Selection of the type and size of the transcatheter valve according to the patient’s individual anatomy is critical to achieving successful results. Therefore, given the increasing frequency of BAV stenosis in younger patients, and the worldwide expansion in the application of TAVR in younger and lower surgical-risk patients, preprocedural multimodality imaging involving CT scan and three-dimensional echocardiography is mandatory to understand the complex and variable anatomy of BAV disease and improve both procedural results and short- and long-term outcomes in these patients.

Unusual Complication

Background: Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is an unusual complication related to various injuries or conditions which involve the mitro-aortic region; it communicates with the left ventricular outflow tract and is associated with a high-risk of redoubtable complications or sudden death. The cerebral and splenic localizations are frequently seen as manifestations of systemic embolism in infective endocarditis. Currently, there are no specific recommendations related to the diagnosis, management, treatment, or further evolution of patients with P-MAIVF and concomitant splenic infarction. This paper presents the case of a 43-year-old Caucasian woman with a late diagnosis of mixed bicuspid aortic valve disease, affected by an under-detected and undertreated episode of infective endocarditis leading to asymptomatic P-MAIVF. Prime clinical and imagistic diagnosis of splenic infarction indicated further extended investigations were required to clarify the source of embolism. Methods: Integrated multimodality imaging techniques confirmed the unexpected diagnosis of P-MAIVF. Results: The case had a fatal outcome following an uncomplicated yet laborious cardiac surgery. Patient death was attributed to a malignant ventricular arrhythmia. Conclusion: The present case raises awareness by highlighting an unexplained and unexpected splenic infarction association with P-MAIVF as a result of infective endocarditis related to mixed bicuspid aortic valve disease.
