Article Synopsis
- Study Purpose
- : The study aims to compare the outcomes of TAVR surgical explantation (TAVR-explant) and redo-TAVR in patients who experienced failures after the initial transcatheter aortic valve replacement (TAVR).
- Findings
- : TAVR-explant was associated with a shorter median time to reintervention compared to redo-TAVR and resulted in higher rates of mortality at both 30 days and 1 year. The reasons for reintervention differed between the two groups, with TAVR-explant showing more prosthesis-patient mismatch and redo-TAVR showing more structural valve degeneration.
- Conclusion
- : Overall, TAVR-explant
Impact of Tricuspid Regurgitation on Outcomes of Mitral Valve Surgery after Transcatheter Edge-to-Edge Repair.

Tricuspid regurgitation (TR) severity after mitral transcatheter edge-to-edge repair (TEER) has been shown to impact outcomes but unknown in patients requiring mitral valve (MV) surgery after TEER. We sought to determine the impact of preoperative TR severity and right ventricular (RV) dysfunction on MV surgery after TEER. From 7/2009 to 7/2020, 260/332 patients in the CUTTING-EDGE registry who underwent MV surgery after TEER had paired echocardiographic evaluation on TR severity, and ≥moderate (2+) vs <2+ TR at the time of index TEER were compared.

Background: There still remains a cohort of the TAVR population who are not suitable for a transfemoral (TF) approach. SS-TAVR is a safe and effective alternative to TF-TAVR and has now become our preferred alternative access route.
Background: Transcatheter aortic valve replacement (TAVR) is a lifesaving procedure for many patients high risk for surgical aortic valve replacement. The prevalence of chronic kidney disease (CKD) is high in this population, and thus a very low contrast volume (VLCV) computed tomography angiography (CTA) protocol providing comprehensive cardiac and vascular imaging would be valuable.
Methods: 52 patients with severe, symptomatic aortic valve disease, undergoing pre-TAVR CTA assessment from 2013-4 at Columbia University Medical Center were studied, including all 26 patients with CKD (eGFR<30 mL/min) who underwent a novel VLCV protocol (20 mL of iohexol at 2.
