Bicuspid aortic valve (BAV)-associated aortopathy is a complex phenomenon, and the current lack of univocal interpretation of its causes and treatment can be ascribed to the multiform nature of its clinical presentation. Although there is strong bias in the literature favoring more aggressive treatment of ascending aortic dilatation in patients with BAV, evidence supporting this opinion is lacking. This review discusses some of the relevant issues relating to causation to facilitate a better analysis of the current recommendations used to guide surgical management, and concludes that treatment should be tailored by individual valvular pathology, clinical phenotype, and relevant comorbidities, using well-documented evidence-based clinical size criteria.

Role of miRNAs in Regulating Ascending Aortic Dilation in Bicuspid Aortic Valve Patients Operated for Aortic Stenosis.

Deregulation of micro-RNAs (miRNAs) may contribute to mechanisms of injury in the bicuspid aortic valve (BAV). Our objective was to investigate the expression of miRNAs in aortic tissue from patients who underwent aortic valve replacement for aortic stenosis and its relationship with aortic dilatation. The study included 78 patients, 40 with bicuspid aortic valve (BAV) and 38 with tricuspid aortic valve (TAV).

Background: Epileptic seizures following adult cardiovascular surgery occur in 0.9-3% of patients, with the condition in 3-12% of these patients progressing to status epilepticus (SE). SE is a severe condition that significantly impacts prognosis and necessitates early diagnosis and treatment.

Transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis and raphe-type bicuspid aortic valve (BAV) is still associated with poor outcomes in terms of increased risk of paravalvular regurgitation, stroke, and permanent pacemaker implantation. There is no definitive consensus on the optimal sizing method for prosthesis selection in this setting. The LIRA method is a supra-annular tailored sizing method specifically designed for bicuspid anatomy that might increase accuracy of prosthesis choice in BAV patients and improve TAVR outcomes.

Background: Data supporting the use of transcatheter aortic valve replacement (TAVR) for bicuspid aortic valve (BAV) is limited compared to tricuspid aortic valve (TAV) anatomy, as the BAV anatomy poses unique challenges to prosthesis expansion and symmetric deployment.
Aims: We aim to compare the acute recoil and asymmetry of the SAPIEN-3 valve between BAV and TAV anatomies and their impact on procedural outcomes.
Methods: We conducted a single-center study of patients who underwent TAVR with the SAPIEN-3 valve.

Background: This study evaluated the midterm outcomes of rapid deployment aortic valve replacement (RDAVR) performed regardless of pathology for various aortic valve diseases at a single center.
Methods: Of the 344 patients who underwent RDAVR using Edwards INTUITY during the study period at our institution, 176 had bicuspid valve diseases (51.2%), 20 had pure aortic regurgitation (5.
