Summary: This study investigates coronary access after transcatheter aortic valve replacement (TAVR) using a self-expanding transcatheter heart valve (THV) in patients with bicuspid and tricuspid aortic valves (BAV vs TAV), based on CT simulation. The results show that coronary access can be challenging or complex in both BAV and TAV patients after TAVR, but BAV patients with type 0 anatomy may have more favorable post-TAVR coronary access.

Summary: This study used finite-element analysis to quantify coronary flow in a patient who underwent TAVR-in-TAVR and found that high implantation depth and device undersize of the second THV can significantly reduce coronary flow. Additionally, a positive correlation was observed between coronary flow and the valve-to-coronary distance.

Summary: The study from Cleveland Clinic demonstrates that the transaxillary approach has become the preferred alternative access strategy for TAVR, showing superior operative outcomes compared to intrathoracic approaches and comparable results to transfemoral approach.

Summary: The study aimed to determine the rate of noncentered coronary ostia and their risk for coronary overlap (CO) and develop an improved orientation strategy for transcatheter aortic valve replacement (TAVR) devices to identify patients at risk for CO and calculate an alternative, CO-free TAVR rotation angle for those patients.

Summary: Arterial tortuosity is associated with increased risk of adverse clinical events after TF-TAVR. The IFT score is a valuable tool for predicting access and bleeding complications, providing risk stratification before the procedure.

Summary: In patients undergoing TAV-in-TAVR, there is a relatively high incidence of moderate to severe PPM, and severe PPM is associated with adverse 1-year outcomes.

Summary: In this study, the outcomes of AVR and root replacement after TAVR explantation were compared. The results showed no differences in short-term mortality and morbidities between the two groups, although they had different clinical characteristics.

Summary: This study examines the association between zip code-level racial, ethnic, and socioeconomic composition and rates of transcatheter aortic valve replacement (TAVR) among Medicare patients. The research found that within major metropolitan areas in the US, zip codes with higher proportions of Black and Hispanic patients and those with greater socioeconomic disadvantages had lower rates of TAVR.

Summary: This study demonstrates a hybrid approach that combines robotic off-pump totally endoscopic coronary artery bypass graft surgery (TECAB) and transcatheter aortic valve replacement (TAVR) to provide complete sternotomy sparing cardiovascular care for patients with severe symptomatic aortic stenosis (AS) and coronary artery disease (CAD).

Summary: Post-implantation CT scans were used to evaluate the geometrical relationship between coronary ostia and valve frame in patients undergoing ViV-TAVR with the ACURATE neo valve. The study found that coronary access following ACURATE neo implantation for ViV-TAVR could potentially be challenging in a significant proportion of patients, especially with consideration to implantation depth.

Summary: This study compared the efficacy of TAVR in failed transcatheter aortic valves (TAVs) versus surgical aortic valves (SAVs) and found that TAVR in TAV failures had higher procedural success with similar procedural safety and mortality compared to TAVR in SAV.

Summary: This study evaluated the hemodynamic performances of balloon-expandable and self-expandable TAVR devices in patients with small aortic annulus. The results showed that despite higher rates of paravalvular leaks, the self-expandable devices achieved better hemodynamic results.

Summary: Based on nationwide data in Germany, older patients with more comorbidities and higher operative risk may have lower in-hospital complications when undergoing transapical transcatheter aortic valve replacement (TA-TAVR) compared to surgical aortic valve replacement (SAVR). However, younger patients <75 years and those with lower operative risk scores of 4-9 may benefit more from SAVR than TA-TAVR.

Summary: Transcatheter aortic valve implantation (TAVR) is the preferred treatment for elderly patients with severe symptomatic aortic stenosis. It is now being expanded to younger patients with lower surgical risk and longer life expectancy. Commissural alignment between native and transcatheter valves is crucial for successful TAVR and has potential benefits for coronary access, hemodynamics, and valve durability. This review provides technical insights and current evidence on achieving commissural alignment and different transcatheter aortic valves.
