Article Synopsis
  • The study investigates whether using barrier dressings during cardiac device surgeries can reduce infection risk by limiting contamination from skin flora.
  • The BARRIER-PROTECT trial is a double-blinded, randomized controlled study involving patients who are undergoing repeat procedures on the same device site.
  • The primary measure is to see if the barrier dressing impacts the positivity of pocket swab cultures post-surgery, potentially indicating a lower risk of infections related to cardiac implantable electronic devices.

Background: Arm restriction after cardiac implantable electronic device (CIED) placement is common practice despite minimal supporting evidence. Patients receive a range of restriction recommendations of variable durations with the goal of reducing complications such as wound dehiscence, infection, lead dislodgement, or hematoma formation. These movement limitations can lead to emotional stress and anxiety, complications such as frozen shoulder, and upper extremity venous thrombosis due to immobilization.

Background: Ipsilateral approach in patients requiring cardiac implantable electronic device (CIED) revision or upgrade may not be feasible, primarily due to vascular occlusion. If a new CIED is implanted on the contralateral side, a common practice is to explant the old CIED to avoid device interaction.

Objective: The purpose of this study was to assess a conservative approach of abandoning the old CIED after implanting a new contralateral device.

Functional mitral regurgitation may have different haemodynamic consequences, clinical implications and treatment options, such as surgical or percutaneous interventions or implanting a pacemaker. Here we present two cases with haemodynamically significant intermittent functional mitral regurgitation as the underlying mechanism of heart failure. The cases underline the importance of a high index of suspicion in patients with intermittent heart failure, and a careful analysis of echocardiographic images with simultaneous ECG, in order to delineate systolic and diastolic mitral regurgitation.

Our aim was to investigate whether there is a correlation between computerized tomography (CT) density measurements of the urinary bladder and urinalysis results. Patients were subdivided into three groups with respect to urinalysis results: Group 1, no leukocytes or erythrocytes detected in urine (n=25); Group 2, erythrocytes detected in urine (n=50); and Group 3, leukocytes and erythrocytes detected in urine (n=98). In CT sections, densitometric measurements had been performed from three zones on each section and groups were compared in terms of densitometry results.
