Prognostic utility of assessing ventricular-arterial coupling in arterial hypertension and cardiovascular diseases.

The assessment of myocardial function and its coupling with the arterial system, called ventricular-arterial coupling (VAC), is of paramount importance in many clinical fields, from arterial hypertension, which is the main cause of cardiovascular diseases and death, to heart failure. VAC has been the subject of studies for several decades both from an energetic cost and the impact it can exert on cardiovascular performance. Although more attention has been paid to the relationship between the left ventricle and the left arterial circuit in compromised hemodynamic stages, VAC has aroused interest in many other aspects of study, from its application in pathologies of the right sections of the heart to its clinical impact in prevention and cardiovascular risk factors.

Pulmonary thromboembolism (PTE) is the third most common cause of acute cardiovascular disease, which can lead to high morbidity and mortality if left untreated. Anatomical and electrophysiological variations and obesity may complicate timely diagnosis and delay required management. While computed tomography pulmonary angiography (CTPA) remains the most accurate diagnostic tool, initial assessments using electrocardiography (ECG) or echocardiography can be helpful in early suspicion.

Background: The rapid advancement of minimally invasive surgical techniques has made laparoscopy a preferred alternative because it reduces postoperative complications. However, inflating the peritoneum with CO2 causes a cranial shift of the diaphragm decreasing lung volume and impairing gas exchange. Additionally, CO2 absorption increases blood CO2 levels, further complicating mechanical ventilation when the lung function is already compromised.

Patent ductus arteriosus (PDA) stenting is a vital intervention for neonates with ductal-dependent blood flow, offering an attractive alternative to surgical shunt placement. Despite its benefits, the procedure poses risks such as ductal spasm, branch pulmonary artery compromise, and pseudoaneurysm formation. This report presents two complex neonatal cases with distinct outcomes.

Laparoscopic cholecystectomy has become the gold standard for treating symptomatic cholelithiasis due to its minimally invasive nature and faster recovery times compared to traditional open surgery, but it is not without risks. A key component of this procedure is the creation of pneumoperitoneum. This is achieved by insufflating the abdomen with carbon dioxide (CO2).
