Background: Ventriculoperitoneal shunt (VPS) remains the main treatment for hydrocephalus. However, VPS revision surgery is very common. Here, we present a case in which the retained ventricular catheter was removed using the endoscopic monopolar instrument.
Methods: We report a case of a 28-year-old female who presented with VPS obstruction. She had two previous shunt revision surgeries due to shunt obstruction. Eleven years after the last one, she presented an abdominal pseudocyst that indicated a total system removal. During VPS revision surgery, a retained ventricular catheter was observed. The endoscopic monopolar instrument was introduced into the retained catheter under direct view. Coagulations in a back-and-forth movement were applied to release inner catheter adhesions. After these steps, the catheter was removed, and a new one was placed through the same route.
Results: The catheter was removed without complications, confirmed by the postoperative cranial computed tomography. The patient remained asymptomatic.
Conclusion: The described technique was effective and avoided ventricular bleeding. Further studies are necessary to validate this method.

Pulsed Field Ablation (PFA) is a new ablation method being rapidly adopted for treatment of atrial fibrillation, which shows advantages in safety and efficiency over radiofrequency and cryo-ablation. In this study, we used an in vivo swine model (10 healthy and 5 with chronic myocardial infarct) for ventricular PFA, collecting intracardiac electrograms, electro-anatomical maps, native T1-weighted and late gadolinium enhancement MRI, gross pathology, and histology. We used 1000-1500 V pulses, with 1-16 pulse trains to vary PFA dose.

Aims: To evaluate clinical outcomes, echocardiographic features, and the efficacy and safety of sacubitril/valsartan compared to valsartan across age groups in the PARAGON-HF trial.
Methods And Results: A total of 4796 participants ≥50 years of age with chronic heart failure (HF) and left ventricular ejection fraction (LVEF) ≥45% were divided into three age groups: <65 years (n = 825), 65-74 years (n = 1772), and ≥75 years (n = 2199). Echocardiograms of 1097 patients were analysed in a standardized fashion at a core imaging laboratory.
Cryopreservation of Human Adult Ventricular Tissue for the Preparation of Viable Myocardial Slices.

Article Synopsis
- * A new cryopreservation method has been developed, allowing for the preparation of LMS from human myocardium at a later time, overcoming the limitations of immediate slice preparation after tissue extraction.
- * Results show that cryopreserved cardiac tissue maintains structural integrity and viability comparable to fresh tissue, enabling longer and more complex experiments in cardiac research.

Article Synopsis
- * Diagnosis was confirmed through endomyocardial biopsy revealing zebra bodies in heart cells, and additional tests showed a specific deep intronic variant affecting the GLA gene and leading to a non-functional truncated protein.
- * The findings suggest that not only is the truncated protein non-functional, but it also inhibits the normal GLA protein's function, emphasizing the need to identify deep intronic mutations for better understanding and treatment of Fabry disease.
Snaring via a Femoral Approach to Facilitate Transvenous Lead Extraction of an Infected Right Ventricular Lead Jailed by a Bioprosthetic Tricuspid Valve.

An 85-year-old woman presented with bacteremia complicated by infective endocarditis with vegetations on the prosthetic mitral valve and right ventricular (RV) lead. The patient had a single-chamber permanent pacemaker with two RV leads, one of which was previously trapped or "jailed" after a bioprosthetic tricuspid valve replacement. Complete transvenous lead extraction including the chronically retained jailed RV lead was achieved via laser extraction assisted by concomitant traction from a superior left subclavian and inferior right femoral venous approach.
