Article Synopsis
  • Cardiac remodeling refers to various changes in the heart's structure and function, which occur in response to different stimuli and can lead to serious conditions like heart failure.
  • It is influenced by factors such as hormonal changes, cell death, inflammation, and energy metabolism, all of which contribute to the heart's deteriorating performance.
  • Recent research highlights the importance of oxidative stress and reactive oxygen species in the remodeling process, suggesting they could be targeted for potential therapy to improve heart health.

Cardiac remodeling is defined as a group of molecular, cellular, and interstitial changes that manifest clinically as changes in the heart's size, mass, geometry, and function after different injuries. Importantly, remodeling is associated with increased risk of ventricular dysfunction and heart failure. Therefore, strategies to attenuate this process are critical.

Inferior vena cava filter embolization is not uncommon and can reach 11.8%. However, device migration to the heart is not frequent and occurs in cases after inferior vena cava filter fracture.

Septic shock is associated with unacceptably high mortality rates, mainly in developing countries. New adjunctive therapies have been explored to reduce global mortality related to sepsis. Considering that metabolic changes, mitochondrial dysfunction and increased oxidative stress are specific disorders within the path of septic shock, several micronutrients that could act in cellular homeostasis have been studied in recent decades.

Heart allotransplantation has become one of the methods of choice in the treatment of severe heart failure. In the face of its difficulties, such as the unmet balance between organ supply and demand, the use of xenotransplantation (XTx) might be an attractive option shortly, even more with the ongoing progress achieved regarding the avoidance of hyperacute rejection and primary organ disfunction, maintenance of xenograft function and control of xenograft growth. To make possible this translational challenge, some points must be taken into account indeed, and they are the equipoise of human benefit and animal suffering, the risk of unknown infections, a well prepared informed consent, ethical and religious beliefs, and the role of cardiac XTx in a ventricular assistance device era.

Heyde syndrome manifests as aortic stenosis associated with gastrointestinal bleeding. We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding. Treatment involves initial correction of anemia and heart failure followed by aortic valve replacement.

Introduction: The pacemaker implantation VDD is considered simpler, faster, less expensive and causes fewer complications compared to DDD. However, the VDD pacemaker has not been widely used in many centers, perhaps for fear of dysfunction of the sinus node and the reduction of atrial sensitivity by the pacemaker during follow-up after implantation.

Objective: To compare patients with DDD and VDD pacemakers regarding the evolution of chronic atrial fibrillation (AF) and length of stay outside this postoperative arrhythmia.

Adrenocortical carcinoma is a rare, aggressive malignancy that features a correspondingly poor prognosis. The disease accounts for 0.2% of all malignancies and despite multimodal therapies, its prognosis remains poor, with a mean survival of <30 months.
