Background: To evaluate the safety and efficacy of percutaneous transcatheter super-selective renal arterial embolization (SRAE) with N-butyl cyanoacrylate (NBCA) for iatrogenic renal hemorrhage.
Methods: Between January 2014 and December 2019, 45 patients (including 18 patients with coagulopathy), who underwent percutaneous transcatheter SRAE with NBCA for iatrogenic renal hemorrhage at our institution, were retrospectively reviewed. The technical success rate, clinical success rate, and embolization-related complications were analyzed. The values of estimated glomerular filtration rate (eGFR), serum creatinine (sCr), and serum urea (sUr) were analyzed at the time of pre-SRAE, post-SRAE, and last follow-up to evaluate the effects of NBCA-based SRAE on renal function.
Results: Diagnostic renal arteriography revealed contrast extravasation in 18 patients and pseudoaneurysms in 27 patients. NBCA mixed with iodized oil in a 1:2-1:4 ratio was the sole embolic agent. No procedure-related mortality or major complications occurred. The technical and clinical success rates were both 100%. The values of eGFR, sCr and sUr were not found to be significantly different between pre-SRAE, post-SRAE and last follow-up (eGFR: 91.52 ± 21.17 vs. 90.98 ± 22.11 vs. 92.14 ± 23.51 mL/min/1.73 m, = 0.729; sCr: 74.73 ± 11.08 vs. 75.27 ± 12.43 vs. 73.95 ± 10.14 μmol/L, = 0.543; sUr: 5.69 ± 0.84 vs. 5.71 ± 0.96 vs. 5.70 ± 0.79, = 0.515, respectively).
Conclusions: Percutaneous transcatheter SRAE with NBCA is a safe and effective treatment modality for iatrogenic renal hemorrhage with no deterioration of renal function.

The use of extracorporeal membrane oxygenation (ECMO) has emerged as a rescue intervention for hemodynamically unstable patients and prophylactic intraprocedural hemodynamic support in the cardiac catheterization laboratory. The prompt initiation of ECMO provides immediate hemodynamic support and allows for the completion of bridging and/or life-saving interventions. However, there are no clinical practice guidelines for the use of extracorporeal support in this area.

Objective: Percutaneous vegetation debulking has been reported to treat tricuspid valve infective endocarditis (TVIE), but data on feasibility compared with conventional surgical strategies are limited. We aimed to compare short-term outcomes of suction debulking with partial venovenous bypass to conventional open surgery in this population.
Methods: This was a single-center, retrospective study that included all patients with isolated TVIE who underwent suction debulking with partial venovenous bypass or tricuspid valve surgery between January 2010 and December 2022.

Subclavian artery pseudoaneurysm (SAP) is a rare but lethal diagnosis, and an important condition that should be detected and managed imperatively. SAP has been seldom described in the literature, explaining the lack of concrete management guidelines. Herein we present a case study of a 63-year-old man with SAP post a transcatheter aortic valve implantation (TAVI) done 8 days prior to current presentation.

Background: Treatment of residual mitral regurgitation (MR) with different percutaneous devices after transcatheter edge-to-edge repair (TEER) has been reported as an alternative option to reclipping or surgery. This review aims at describing the different transcatheter strategies available and their results when managing residual MR after TEER.
Methods: A literature search was undertaken across Pubmed, ScienceDirect, SciELO, DOAJ, and Cochrane library databases, to identify article reporting patients with post-TEER residual MR managed by a transcatheter approach that did not involve only the implantation of new clips.

Patent ductus arteriosus (PDA) stenting is a vital intervention for neonates with ductal-dependent blood flow, offering an attractive alternative to surgical shunt placement. Despite its benefits, the procedure poses risks such as ductal spasm, branch pulmonary artery compromise, and pseudoaneurysm formation. This report presents two complex neonatal cases with distinct outcomes.
