Coronary artery disease (CAD) is prevalent in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). Computed tomography-derived fractional flow reserve (CT-FFR) may provide non-invasive functional assessment using existing TAVI planning imaging to evaluate CT-FFR diagnostic performance compared with invasive coronary angiography (ICA) for identifying...

Is routine chest X-ray necessary after ultrasound-guided TIVAP insertion through the internal jugular vein?
This study evaluated routine chest X-ray necessity following ultrasound-guided totally implantable venous access port (TIVAP) placement via internal jugular vein.
Awake off-pump no-touch aorta coronary artery bypass grafting in a patient with interstitial lung disease during the COVID-19 pandemic
Off-pump coronary artery bypass grafting (OPCABG) is favoured to reduce surgical trauma during myocardial revascularisation. Severe chronic respiratory conditions, such as interstitial lung disease, are known to significantly complicate perioperative management and long-term survival. For patients with a history of serious chronic respiratory or advanced respiratory disease, awake OPCABG under...
Factors associated with cerebrovascular complications in a cohort of patients with autosomal dominant polycystic kidney disease in South Africa
The prevalence of intracranial aneurysms (IAs) in individuals with autosomal dominant polycystic kidney disease (ADPKD) is about 6%–25%. This rate is higher than that of the general population and is associated with increased morbidity and mortality. Studies in Africa are sparse. Therefore, we aimed to describe the clinical manifestations, imaging features, and long-term prognoses of patients...
Prognostic value of preoperative inflammatory and renal markers (SII, NLR, creatinine) on postoperative hospital stay and clinical outcomes in patients undergoing isolated coronary artery bypass graft surgery: a comprehensive analysis
Coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) induces a systemic inflammatory response, often leading to delayed recovery. This study investigated the predictive value of preoperative inflammatory markers (neutrophil-to-lymphocyte ratio [NLR], systemic immune-inflammation index [SII]) and serum creatinine on the length of hospital stay (LOS) following isolated CABG.
An analysis of imaging modalities to assess the right and left heart in pulmonary hypertension with left-to-right shunts
Pulmonary hypertension (PH) secondary to congenital left-to-right shunts leads to serious consequences in sub-Saharan Africa. This study used various imaging modalities to assess right and left heart dimensions and functions in patients with secondary PH.
Comparison of postoperative complication incidences with different anaesthetic agents used in open heart surgery: a retrospective study
The choice of anaesthetic agent for open-heart surgery (OHS) may influence perioperative physiology and outcomes. This study compared the effects of sevoflurane and propofol on intraoperative parameters and postoperative complications.
Mechanical vs. sutureless aortic valve replacement: clinical outcomes and the contribution of preoperative multislice CT
Heart valve disease is a significant cause of morbidity and mortality, and aortic valve replacement (AVR) is a common treatment option. Recently, sutureless biological valves have gained increasing use. This study aimed to evaluate the concordance between preoperative computed tomography-derived annulus measurements and valve sizes implanted during surgery rather than the direct clinical impact...
Body mass index predicts ventricular repolarisation in obese children: differential effects across obesity levels
Childhood obesity is associated with cardiac electrical remodelling, yet the relationship between body mass index (BMI) and ventricular repolarisation (VR) heterogeneity remains incompletely characterised in paediatric obesity.
Investigation of the effect of sternum retractor opening distance on postoperative pain in cardiac surgery operations performed with median sternotomy
Pain that develops after cardiac surgery can negatively affect early recovery. In this study, we aimed to investigate the effect of sternal retractor opening on post-sternotomy pain in cardiac surgeries performed with median sternotomy.
