Background: Patients with low-flow, low-gradient (LFLG) aortic stenosis (AS) have precarious hemodynamics and are a fragile population for intervention. Quantification of aortic valve calcification (AVC) severity is a critical component of the evaluation for transcatheter aortic valve replacement (TAVR); this study aims to further clarify its utility for risk stratification in LFLG AS.
Methods: This retrospective study evaluated 467 patients with LFLG AS undergoing TAVR at a large quaternary-care hospital from January 2019 to December 2021.
Article Synopsis
- * In a study of 463 patients, LV remodeling was classified as adaptive (normal or concentric remodeling) in 57.4% and maladaptive (hypertrophy) in 42.6%; those with maladaptive remodeling had worse outcomes post-TAVR.
- * Maladaptive LV remodeling increased the risk of heart failure hospitalization and death, regardless of gender, suggesting its assessment could enhance risk stratification over traditional ejection fraction measures for LF AS patients.
Spontaneous coronary artery dissection (SCAD) is one of the causes of acute coronary syndrome (ACS) that is increasingly recognized in young to middle-aged women without typical coronary risk factors. This case report describes a 46-year-old male with a rare presentation of SCAD involving the left main (LM) coronary artery. The patient underwent an emergency coronary angiogram for high-risk ACS and had percutaneous coronary intervention (PCI) of LM due to active ischemia and hemodynamic instability.
