Transcatheter aortic valve implantation in acute decompensated aortic stenosis.
Catheter Cardiovasc Interv
September 2020
Objectives: To assess the safety and efficacy of first-line transcatheter aortic valve implantation (TAVI) in patients presenting with acute decompensated aortic stenosis (ADAS).
Background: ADAS is common and is often treated medically or using balloon aortic valvuloplasty in the first instance. This temporizing measure results in suboptimal outcomes.
Background: Angina is common in hypertrophic cardiomyopathy (HCM) and is associated with abnormal myocardial perfusion. Wave intensity analysis improves the understanding of the mechanics of myocardial ischemia.
Objectives: Wave intensity analysis was used to describe the mechanisms underlying perfusion abnormalities in patients with HCM.
Article Synopsis
- * New technologies, like percutaneous aortic valve replacement (PAVR) and coronary pulse wave analysis, allow for immediate assessment of blood flow changes after treating valvular stenosis.
- * The study found that before PAVR, the coronary suction wave decreased as heart rate increased, but post-PAVR, this wave normalized, indicating improved heart response and potentially relieving angina symptoms.
