Left subclavian access for pentaspline pulsed field ablation system: A feasible option in bilateral femoral vein thrombosis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStandard femoral venous access may not be feasible in patients with inferior vena cava (IVC) obstruction or bilateral deep vein thrombosis (DVT), necessitating alternative venous routes. CASE SUMMARY: We report the case of a 73-year-old man with paroxysmal AF, antithrombin III deficiency, and chronic bilateral femoral and iliac vein thrombosis. After a failed prior attempt at PVI due to inaccessible femoral veins, a left subclavian approach was selected based on favorable ultrasound imaging. Under deep sedation, subclavian venous access was obtained and a Pentaspline PFA system (FaraWave™) was used via a steerable sheath. Transseptal puncture was performed using the VersaCross™ RF pigtail system under fluoroscopic and transesophageal echocardiographic guidance. Ablation was successfully delivered to all pulmonary veins, including a left common trunk, using standard electroporation protocols. Total procedure time was 117 minutes. No complications occurred, and the patient was discharged the following day in stable condition.
conclusionThis case demonstrates the technical feasibility and safety of using the Pentaspline PFA system via left subclavian venous access in a patient with extensive lower extremity venous thrombosis. The approach enabled successful PVI in a complex clinical scenario where traditional femoral access was precluded. While alternative access routes for PFA are rarely reported, this case expands the potential use of superior venous access and may serve as a reference for similar high-risk patients. Such procedures should be reserved for experienced centers with advanced imaging and transseptal expertise.
