Intracardiac migration of a vena cava filter (VCF) is a rare but potentially fatal complication. We describe a unique case of intracardiac migration of a permanent VCF with extensive thrombus propagating into the inferior vena cava and right atrium. Percutaneous thrombectomy with the AngioVac (AngioDynamics, Latham, NY) device was performed, and the permanent VCF was percutaneously removed.

Background: In patients with post-thrombotic syndrome (PTS), stent recanalization of iliofemoral veins or the inferior vena cava can restore venous patency and improve functional outcomes. The risk of stent thrombosis is particularly increased during the first 6 months after intervention. The ARIVA trial tested whether daily aspirin 100 mg plus rivaroxaban 20 mg is superior to rivaroxaban 20 mg alone to prevent stent thrombosis within 6 months after stent placement for PTS.

Purpose: We present the case of a rare extrahepatic portocaval shunt that resulted in communication of the portal vein and the inferior vena cava (IVC) at the level between two right renal veins that was incidentally diagnosed with contrast-enhanced computed tomography (CECT) in an asymptomatic patient.
Methods: A woman in her sixties with abdominal pain and diarrhea of unclear origin underwent exploratory abdominal CECT.
Results: The CECT incidentally revealed an extrahepatic portocaval shunt, whereby a vessel arising from the portal vein superior to the confluence of the superior mesenteric and splenic veins drained into the posterior aspect of the IVC between two right renal veins.

Background: This study aimed to investigate the clinical outcomes of percutaneous transluminal angioplasty (PTA) in patients undergoing hemodialysis with different types of superior vena cava obstruction (SVCO) lesions.
Methods: This retrospective observational study recruited patients undergoing hemodialysis with SVCO and analyzed the clinical characteristics of SVCO. Patency rates were collected for patients treated with PTA and were assessed using the t-test, U-test, log-rank test and survival analyses such as the Kaplan-Meier method.

Background: Coronary sinus (CS) lead placement in persistent left superior vena cava (PLSVC) cases is challenging because of the poor backup force of the guiding catheter within the enlarged CS. Active fixation Quadripolar leads (Attain Stability™ Quad 4798, Medtronic) can expand choice to CS branches with limited access; however, no cases of anchoring to the main body of the CS have been published to date.
Case Summary: We describe a case of cardiac resynchronization therapy pacemaker upgrade in a 79-year-old female who developed pacing-induced cardiomyopathy after pacemaker implantation via the right superior vena cava (SVC) for atrioventricular block eight years ago wherein PLSVC was revealed during the procedure.

Background: The superior vena cava (SVC) acts as a non-pulmonary vein (PV) trigger for atrial fibrillation (AF) in 2%-6% of patients and harbours 25%-40% of non-PV foci. Approximately 10% of patients with AF have epicardial connections (ECs) between the atrium and PV inside the PV isolation lines, which are associated with AF recurrence. However, the contribution of EC(s) between the SVC and right atrium (RA) to subsequent AF remains unknown.
