Background: As transcatheter aortic valve (TAV) replacement is increasingly used in patients with longer life expectancy, a sizable proportion will require redo TAV replacement (TAVR). The unique configuration of balloon-expandable TAV (bTAV) vs a self-expanding TAV (sTAV) potentially affects TAV-in-TAV outcome.
Objectives: The purpose of this study was to better inform prosthesis selection, TAV-in-TAV outcomes were assessed according to the type of initial and subsequent TAV.
Methods: Patients from the Redo-TAVR registry were analyzed using propensity weighting according to their initial valve type (bTAV [n = 115] vs sTAV [n = 106]) and subsequent valve type (bTAV [n = 130] vs sTAV [n = 91]).
Results: Patients with failed bTAVs presented later (vs sTAV) (4.9 ± 2.1 years vs 3.7 ± 2.3 years; P < 0.001), with smaller effective orifice area (1.0 ± 0.7 cm vs 1.3 ± 0.8 cm; P = 0.018) and less frequent dominant regurgitation (16.2% vs 47.3%; P < 0.001). Mortality at 30 days was 2.3% (TAV-in-bTAV) vs 0% (TAV-in-sTAV) (P = 0.499) and 1.7% (bTAV-in-TAV) vs 1.0% (sTAV-in-TAV) (P = 0.612); procedural safety was 72.6% (TAV-in-bTAV) vs 71.2% (TAV-in-sTAV) (P = 0.817) and 73.2% (bTAV-in-TAV) vs 76.5% (sTAV-in-TAV) (P = 0.590). Device success was similar according to initial valve type but higher with subsequent sTAV vs bTAV (77.2% vs 64.3%; P = 0.045), primarily because of lower residual gradients (10.3 mm Hg [8.9-11.7 mm Hg] vs 15.2 mm Hg [13.2-17.1 mm Hg]; P < 0.001). Residual regurgitation (moderate or greater) was similar after bTAV-in-TAV and sTAV-in-TAV (5.7%) and nominally higher after TAV-in-bTAV (9.1%) vs TAV-in-sTAV (4.4%) (P = 0.176).
Conclusions: In selected patients, no association was observed between TAV type and redo TAVR safety or mortality, yet subsequent sTAV was associated with higher device success because of lower redo gradients. These findings are preliminary, and more data are needed to guide valve choice for redo TAVR.

Despite continued advancements in transcatheter aortic valve implantation (TAVI) techniques, the incidence of permanent pacemaker implantation (PPI) remains substantial. Established predictors of PPI include advanced age, pre-existing electrocardiographic conduction abnormalities, prosthetic valve type, implantation depth, and anatomical parameters, such as membranous septum length, which are currently under active investigation. In routine clinical practice, the management strategy often involves the temporary placement of a transvenous pacemaker lead, followed by a period of observation.

Objective: Valve selection in acute type A aortic dissection (ATAAD) requiring aortic root replacement is challenging given the clinical acuity, unknown patient preferences, risk of surgical bleeding, and limited life expectancy. We sought to identify long-term outcomes of mechanical versus bioprosthetic aortic root replacement in young patients with ATAAD.
Methods: Retrospective review of our institution's database of ATAAD was conducted to identify patients aged 65 years and younger who underwent mechanical Bentall (mech-Bentall) or bioprosthetic Bentall (bio-Bentall) for ATAAD from 2002 to 2022.

Objective: To compare the clinical outcomes of double-valve replacement (DVR) using bovine pericardial and porcine bioprostheses, using a nationwide administrative claims database.
Methods: Adult patients (age ≥40 years) who underwent bioprosthetic DVR between 2003 and 2018 were identified from the Korean National Health Insurance Service database. The outcomes of interest were all-cause mortality, cardiac mortality, and valve-related events, including the incidences of reoperation, endocarditis, systemic thromboembolism, and major bleeding.

Objective: Endovascular treatment of cerebrovascular diseases can be challenging in patients with difficult access routes. We describe a turn-over technique using a balloon guiding catheter (BGC) via the transfemoral approach to perform neuroendovascular treatment.
Case Presentation: An 80-year-old female with a recurrent right middle cerebral artery (MCA) aneurysm after coil embolization underwent successful stent-assisted coiling via the transfemoral approach.

Infective endocarditis is a potentially fatal condition that can present with non-specific symptoms and rare hematologic manifestations, posing significant diagnostic challenges. We report a compelling case of a 67-year-old male with a history of type 2 diabetes, hypertension, and hyperlipidemia who sought medical attention for a five-month history of progressive iron deficiency anemia, accompanied by weight loss, fatigue, and vague constitutional symptoms. Initial extensive workup, including computed tomography of the thorax, abdomen, and pelvis, gastroscopy, colonoscopy, and transthoracic echocardiography, failed to identify an underlying cause.
