We aimed to evaluate the incidence of residual shunt after patent foramen ovale (PFO) closure and analyze the anatomical features of PFO to determine the risk factors for significant residual shunt after PFO closure. Ninety-two patients who underwent PFO closure at our center between September 2021 and June 2022 were consecutively enrolled. Transthoracic saline contrast echocardiography was performed at 6 and 12 months postoperatively to evaluate the presence of a significant residual shunt. Preoperative measurements of the anatomical structures of PFO were performed using transesophageal echocardiography. Binary logistic regression analysis was performed to determine the risk factors for significant residual shunt at 12 months after PFO closure, and receiving operating characteristic curves were plotted to calculate the cutoff values. At the follow-up 12 months postoperatively, 22 (24%) of the 92 patients showed significant residual shunt. Thicker secondary septum and longer tunnel were independent risk factors for significant residual shunt after PFO closure. In particular, patients with secondary septum thickness > 6.55 mm or tunnel length > 10.10 mm were more susceptible to significant residual shunt. This study may guide clinicians in developing individualized PFO treatment strategies.

Background: Intracardiac echocardiography (ICE) appears to be a potential alternative for percutaneous left atrial appendage occlusion (LAAO) to transesophageal echocardiography (TEE). Thus, a meta-analysis was performed comparing ICE vs. TEE for LAAO guidance.

Objectives: Vascular access thrombosis (VAT) is a common complication in patients with end-stage renal disease (ESRD), significantly impacting hemodialysis efficacy and patient survival. Currently, temporary dialysis access is typically established deep vein catheterization (VC), however, this method is highly invasive and associated with risks of infection and other complications. This study aims to explore the feasibility of using direct anastomosis indwelling needle puncture (DAINP) for temporary dialysis access.

Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.
Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.
Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.

Cerebral arteriovenous malformations (AVMs) are tangles of abnormal vessels with early arteriovenous (AV) shunting that can lead to intracerebral hemorrhage, seizures, neurologic deficit, or headache. To date, only a few cases of carcinomas metastasizing to pre-existing cerebral AVMs have been reported in the literature. However, renal clear cell carcinoma (RCC) brain metastases that exhibit early AV shunting, where AVM pathology is not present, are extremely rare.
