Atrial Fibrillation, Pulmonary Vein Mapping Techniques

Leave a Comment / Cathlab Protocols, Electrophysiology /

Based on the understanding of the atrial fibrillation initiation mechanism by focal discharges in the pulmonary veins, focal ablation appeared to be a less effective ablative technique than electrical disconnection at the PV ostium. The unpredictability, inconsistent inducibility, and risk of repeatedly inducing AF during the procedure limit ablation guided by mapping focal ectopy, which […]

PCI Post TAVI with Core Valve

Cathlab Protocols, Structural Heart /

Unplanned PCI post TAVI is uncommon, and the incidence decreases over time. In the first two years following TAVI, acute coronary syndrome is the primary rationale for PCI; thereafter, chronic coronary syndromes are more common. Balloon-expandable and self-expandable bioprostheses appear to have no differences in the frequency or success of unplanned PCIs after TAVR. Hardware’s

Coronary Angiogram Protocols Post TAVI With Core Valve

Leave a Comment / Cathlab Protocols, Structural Heart /

Following TAVI, coronary interventions can be technically challenging. The selective cannulation of the coronary ostia, which is dependent on patient anatomy, valve type and design, and implantation parameters including implantation depth and the orientation of the commissural tabs with respect to the ostia, is the most difficult part of the surgery. The following, we summarise

QFR and OFR In the Assessment of Intermediate CAD

Leave a Comment / Adult Interventions, CathLab /

QFR and OFR in the Assessment of intermediate CAD that may benefit from percutaneous coronary intervention, a physiological lesion assessment is indicated. The optical flow ratio (OFR) is a more modern approach for the quick and automated assessment of coronary physiology from intracoronary optical coherence tomography (OCT). The quantitative flow ratio (QFR) was created to

Ventricular Septal Defect Closure

Leave a Comment / CathLab, Cathlab Protocols /

The use of a transcatheter device to congenital Ventricular Septal Defect Closure Is an appealing and practical alternative to surgery. Isolated congenital VSDs are the most prevalent type of congenital heart disease in children and babies, accounting for 25–35 percent of all cardiac abnormalities. The majority of VSDs are found in the ventricular septum’s membranous

Cathlab Protocols: Balloon Mitral Valvuloplasty (BMV)

Leave a Comment / CathLab, Cathlab Protocols /

Balloon Mitral Valvuloplasty is an Interventional treatment used to increase the opening of a narrowed (stenotic) valve The most common cause of native mitral stenosis is rheumatic heart disease. The obstruction to inflow resulting from fusion of the valve commissures is the pathophysiologic problem in these patients. Left atrial hypertension, atrial arrhythmias, pulmonary hypertension, and

Angiogram Radial Approach

Leave a Comment / CathLab, Cathlab Protocols /

Angiogram Radial Approach – The most compelling reason for adopting Trans-radial access is the increased patient safety that results from the virtual elimination of access site bleeding and vascular complications. In addition, TRA is associated with early sheath removal, improved patient comfort, faster recovery, and lower costs in comparison with transfemoral access Pre- procedure Assessment
