Background: Calcific aortic stenosis is increasingly recognized as a major determinant of mortality in the aging subset of patients with the ultra-rare Hutchinson-Gilford progeria syndrome (HGPS), particularly as survival improves with lonafarnib therapy. However, the optimal treatment strategy for severe aortic stenosis in this population remains undefined.
Case Summary: We report the first successful case of combined surgical aortic valve replacement and coronary artery bypass grafting in a severely symptomatic 21-year-old man with HGPS, severe calcific aortic stenosis, and coronary artery disease.
Discussion: Despite anatomical and procedural challenges, surgical valve replacement represents a reasonable treatment option in patients with HGPS when transcatheter or alternative approaches are not feasible. A multidisciplinary approach is essential to optimize outcomes in this high-risk population.
Take-home Message: Surgical aortic valve replacement may be considered among the potential treatment options for selected patients with HGPS.

Objectives: This study explores the impact of lower baseline aortic valve (AV) mean gradients on the clinical outcomes of patients with low-gradient aortic stenosis (LG AS) post-transcatheter aortic valve replacement (TAVR). Additionally, the study aims to understand the predictors of a lower baseline AV mean gradient (MG).
Background: Reduced left ventricular ejection fraction (LVEF) and low-flow states are known to correlate with worse clinical outcomes.

Patients with atrial fibrillation, venous thrombosis, and mechanical heart valve (MHV) regularly undergo procedures on a daily basis, for which they require bridging anticoagulation, but this poses significant challenges. Bridging anticoagulation involves temporary interruption of long-term anticoagulation therapy for procedures and continued overlap with short-acting anticoagulants during perioperative period. Heparin-based agents are often used for overlapping in perioperative period to reduce the risk of thromboembolism, but the evidence for benefit particularly in patients with MHV remains limited.

Background: Chronic kidney disease (CKD) is associated with a higher prevalence of valvular diseases and increased mortality from cardiovascular causes. Factors that influence the genesis of cardiac valve calcification (CVC) in these patients are not well-defined.
Objective: To determine the risk factors for valvular calcification in patients with CKD.

Background: Transcatheter pulmonary valve implantation (TPVI) has emerged as a viable alternative to surgical pulmonary valve replacement for patients with congenital heart disease and right ventricular outflow tract dysfunction. However, its adoption in low-resource settings has been limited.
Case Summary: We report the first successful TPVI procedures in Tanzania.
