We will report a case of a desmoid tumour (DT), which developed at the surgical site of the pacemaker after a late childhood heart transplant. Patients with idiopathic dilated cardiomyopathy followed up in the paediatric cardiology service. It evolved with the dissociation of ventricular rhythm caused by severe heart failure, which led to the implantation of a cardiac resynchronization device prior to heart transplantation.

Article Synopsis
  • Pulmonary endarterectomy (PEA) is the primary treatment for chronic thromboembolic pulmonary hypertension (CTEPH), and this study reviews the outcomes of 102 patients over a 10-year period, highlighting advancements in surgical techniques.
  • The authors divided the patients into three groups based on the timing of their surgery and noted that postoperative complications decreased significantly in the most recent group (group 3) compared to the earlier groups.
  • Their findings indicate that the improvements made in anesthetic and surgical methods contributed to better patient outcomes, with a majority achieving a functional class of I-II within 3 to 6 months after surgery.

The pathophysiological mechanisms underlying chronic thromboembolic pulmonary hypertension (CTEPH) are still unclear. Endothelial cell (EC) remodeling is believed to contribute to this pulmonary disease triggered by thrombus and hemodynamic forces disbalance. Recently, we showed that HSP70 levels decrease by proatherogenic shear stress.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism, characterized by non-resolving fibro-thrombotic obstructions of large pulmonary arteries. Pulmonary endarterectomy (PEA) is the treatment of choice for the disease, significantly improving survival. Patients with worse hemodynamic profile have worse prognosis after surgery, raising the question of whether the use of medical therapy prior to surgery to optimize hemodynamics could improve outcomes.
