Pacing Ratio Changes of an Implanted Permanent Pacemaker After Transcatheter Aortic Valve Implantation

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background In some patients, transcatheter aortic valve implantation (TAVI) is associated with conduction disturbances, necessitating permanent pacemaker implantation (PMI). The clinical course of conduction disturbances after PMI, based on the type of TAVI valve, remains unclear.

TAVI Using a Self-Expandable Device for Aortic Regurgitation Following LVAD Implantation

The Thoracic & Cardiovascular Surgeon Reports, 2019
Background In patients treated by left ventricular assist device (LVAD), aortic regurgitation (AR) may occur. Secondary surgery to correct AR is considered high risk.

The impact of trans-catheter aortic valve replacement induced leftbundle branch block on cardiac reverse remodeling [PDF]

, 2017
Background Left bundle branch block (LBBB) is common following trans-catheter aortic valve replacement (TAVR) and has been linked to increased mortality, although whether this is related to less favourable cardiac reverse remodeling is unclear.

Patient blood management and surgery: Impact of new surgical techniques on transfusion needs

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Patient blood management (PBM) is a multidisciplinary approach aimed at reducing the use of blood products. It considers the patient's own blood as a valuable resource to preserve and seeks to avoid the routine use of transfusions to treat anaemia.

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Hemodynamic Performance of a Self-Expanding Transcatheter Aortic Valve with an Intra-Annular Leaflet Position in Patients with a Small Aortic Annulus

Medicina
Background and Objectives: Transcatheter aortic valve implantation is associated with a higher risk for elevated trans-prosthetic gradients and prosthesis-patient mismatch in patients with a small aortic annulus.

Frequency of and Prognostic Significance of Atrial Fibrillation in Patients Undergoing Transcatheter Aortic Valve Implantation [PDF]

, 2016
The prognostic implications of preexisting atrial fibrillation (AF) and new-onset AF (NOAF) in transcatheter aortic valve implantation (TAVI) remain uncertain.
