Entrapment of a spline from a multielectrode mapping catheter in the side hole of a nonsteerable guiding sheath, with dislodgement and subsequent suction retrieval of a proximal spline electrode

How to perform a transseptal puncture safely and effectively

“…In patients with atrial septal defect closure devices there are two options: to puncture through the device or puncture below the device. As much as possible, puncturing through the device should be avoided, as there is a risk of the catheters being trapped 25 , and punctures posterior and inferior to the device should be preferred. If the puncture is made through the device, the access should be sufficiently dilated (using balloons) to facilitate the movement of sheaths and catheters.…”

Coronary sinus spasm with catheter entrapment and adjacent coronary artery compression during an ablation procedure in a child

“… 3 , 4 Rare cases have been reported of catheters wedged in pulmonary 5 or iliac 6 veins, the tricuspid valve apparatus, 7 and the Thebesian valve. 8 Catheter-to-catheter entanglement has also been described, such as in a side hole of a sheath 9 or in the grid of a mapping catheter. 10 In several cases, the trapped catheter required surgical excision with or without concomitantly addressing damage to the involved cardiac structure.…”

Cómo realizar una punción transeptal de manera segura y exitosa

“…En pacientes con dispositivos de cierre de defectos del tabique interauricular, existen dos opciones: puncionar a través del dispositivo o puncionar por debajo de él. En lo posible, se debe evitar la punción a través del dispositivo, ya que hay riesgo de atrapamiento de los catéteres25 y se debe preferir la punción en una posición posterior e inferior al dispositivo. Si se punciona a través del dispositivo, se debe dilatar el acceso lo suficiente (mediante el uso de balones) para facilitar el movimiento de camisas y catéteres.…”
