Preemptive temporary right ventricular assist device implantation for severe biventricular heart failure: A case series.

Purpose: We sought to investigate the clinical results of preemptive temporary right ventricular assist device (RVAD) placement with left ventricular assist device (LVAD) implantation for anticipated right ventricular failure.

Methods: Patients at risk for right ventricular failure were identified by the heart team. After median sternotomy, Protekduo (LivaNova, London, UK) dual-stage cannula was inserted from the right internal jugular vein under fluoroscopy guidance, and advanced into the pulmonary artery to the bifurcation of the main pulmonary artery.

[A rare observation of the giant urinary bladder stone].

A rare observation of iatrogenic damage of the urinary bladder by the needles used for osteosynthesis, which were encrusted with salts and lead to the formation of a giant bladder stone weighing 720 g, is given. The curiosity of the situation was associated with the long-term observation and the surgical removal of the stone and foreign bodies 19 years after initial detection due to the development of upper urinary tract complications.
