Background: A three-dimensional (3D) mapping system is essential to reduce radiation exposure during catheter ablation. When using the CARTO 3D mapping system, only the catheter with magnetic sensor can visualize its location. However, once target chamber matrix is created using the catheter, even the catheters without magnetic sensors (CWMS) can enable visualization. We aimed to investigate the feasibility and safety of placing a CWMS in the coronary sinus (CS) without fluoroscopic guidance.
Methods: The study group comprised 88 consecutive patients who underwent catheter ablation. CWMS placement was performed without fluoroscopic guidance in 47 patients and with fluoroscopic guidance in 41 patients. Placement without fluoroscopic guidance was performed after creating a visualization matrix of the CS, right atrium, and superior vena cava using a catheter with a magnetic sensor. Feasibility and safety were compared between the two groups.
Results: Successful catheter placement was achieved in all patients without fluoroscopic guidance, with no inter-group difference in the median procedure time: with guidance, 120.0 [96.0-135.0] min, and without guidance, 110.0 [97.5-125.0] min; = .22. However, radiation exposure was significantly shorter, and the effective dose was lower without fluoroscopic guidance (0 [0-17.5] s and 0 [0-0.004] mSv, respectively) than with fluoroscopic guidance (420.0 [270.0-644.0] s and 0.73 mSv [0.36-1.26], respectively); both < .001.
Conclusions: CWMS placement without fluoroscopic guidance is feasible, safe to perform, and does not involve complications. Our technique provides an option to decrease radiation exposure during catheter ablation and electrophysiological testing.

Percutaneous balloon pericardiotomy (PBP) has emerged as a less invasive alternative to surgical interventions for recurrent severe pericardial effusion (PE), particularly in patients with malignancies. This study evaluates the safety and efficacy of PBP in patients with recurrent severe PE. A total of 42 patients with recurrent severe PE underwent PBP between March 2008 and July 2024.

Infectious myocarditis (IM) and infective endocarditis (IE), sometimes associated with infection of the surrounding mediastinal tissue or embolic complications caused by residual implantable cardioverter defibrillator (ICD) lead material embedded in the ventricle, present a significant challenge for cardiac surgeons due to the difficulty of precisely locating the old intracardiac pacing lead remnants because of the heart's continuous movement. We present the case of successful two-stage elective sternotomy extraction of two residual defibrillator leads, one trapped in the left innominate vein, easily removed after veinotomy without cardiopulmonary bypass (CPB), and the other embedded intramyocardially in the inferior wall of the right ventricle, successfully removed under CPB after fluoroscopic guidance. The patient was discharged four weeks post-operation without complications.

Objectives: To evaluate outcomes after implementation of a preoperative protocol requiring fluoroscopic guidance in patients undergoing thoracoabdominal aortic aneurysm (TAAA) repair identified as being at risk for spinal drain placement complications.
Design: This retrospective analysis included patients who underwent spinal drain placement for TAAA repair between November 2013 and November 2018. Patient outcomes were assessed before (control) and after (study) protocol implementation.

Objective: To determine the feasibility, yield, and safety of fluoroscopic-guided aspiration of the acutely dislocated total hip arthroplasty (AD-THA).
Materials And Methods: IRB-approved, retrospective review of fluoroscopic-guided aspirations of AD-THA (January 2005-December 2023) was performed. Data from electronic charts and fluoroscopy images/reports were obtained.

Background: Hepatic artery infusion pump (HAIP) chemotherapy is a locoregional treatment for intrahepatic malignancies. HAIPs are surgically implanted, and the catheter tip is typically inserted into a ligated gastroduodenal artery stump. Potential complications at the catheter insertion site include dehiscence, pseudoaneurysm or extravasation, and adjacent hepatic arterial stenosis and thrombosis.
