High prevalence of obstructive sleep apnea in a surgical aortic valve replacement cohort: an observational study Open
Study Objectives A high prevalence of sleep apnea has been reported among transcatheter aortic valve replacement (AVR) patients; however, the prevalence of sleep apnea in the younger and relatively healthier population of surgical AVR (SAV…

Navigating the Unexpected: Iatrogenic Aortic Injuries during Transcatheter Aortic Valve Replacement (TAVR) Open
The introduction of transcatheter aortic valve replacement (TAVR) has undeniably changed the landscape of valvular heart disease management over the last two decades. A reduction in complications through improvements in techniques, experie…

Aortic annulus rupture after transcatheter aortic valve replacement: successful management of a dangerous complication Open
Objective Aortic annulus rupture remains one of the most fatal complications of TAVR. While attempts have been made to describe and predict this complication, the data remains insufficient without evidence-based guidelines for management o…

Infective endocarditis of quadricuspid aortic valve Open
Background Infective endocarditis of the aortic valve is a relatively common disease presentation, with surgical intervention a mainstay of treatment in severe cases. Quadricuspid aortic valves are a rare spontaneous developmental anomaly …

Membranous Septum Length Predicts New Conduction Abnormalities in Surgical Aortic Valve Replacement - A novel predictor for PPMI after SAVR Open
PURPOSE The membranous septum (MS) length measured by cardiac computed tomography (CT) is useful for the prediction of permanent pacemaker implantation (PPMI) and new left bundle branch block (LBBB) after transcatheter aortic valve replace…

Two cases of acute endocarditis misdiagnosed as COVID‐19 infection Open
The COVID‐19 pandemic has presented countless new challenges for healthcare providers including the challenge of differentiating COVID‐19 infection from other diseases. COVID‐19 infection and acute endocarditis may present similarly, both …

Systematic Transfemoral Transarterial Transcatheter Aortic Valve Replacement in Hostile Vascular Access Open
BackgroundTraditionally, hostile peripheral access patients undergo TAVR via alternative access. We describe the "transfemoral-first" (TF-1) approach in patients with hostile peripheral access.MethodsClinical and procedural data were obtai…

Aorto-Right Ventricular Fistula Post-Transcatheter Aortic Valve Replacement: Multimodality Imaging of Successful Percutaneous Closure Open
•Aorto-right ventricular fistula is a rare diagnosis and is on the spectrum of aortic periannular rupture.•Multimodality imaging is crucial in identifying aortic periannular rupture, defining its course, and for preprocedural planning.•We …
