Suture-based techniques versus manual compression for femoral venous haemostasis after electrophysiology procedures

This novel approach that combines high-power, short-duration (HPSD) and very high-power, short-duration (vHPSD) ablation successfully achieved superior vena cava (SVC) isolation with a shorter procedural time, shorter radiofrequency (RF) duration, and lower RF energy than those with ablation index (AI)-guided middle-power, middle-duration (MPMD) ablation for patients with atrial fibrillation (AF).

Patients with successful His-Bundle Pacing (HBP) had a narrower paced. QRS compared to patients who had Right Ventricular Pacing (RVP) because of failed HBP. After 6-months of high pacing burden, HBP was superior to RVP in preserving left ventricular systolic function and shape in patients with normal ejection fraction at baseline. Pacing induced cardiomyopathy developed more often in patients with RVP than in those with HBP.

This graphical abstract shows a study of 31 214 AF ablation procedures (2012–2019, >99% in the entire country) with a 30-day mortality rate of 0.1% (n = 32). Significant risk factors for death included kidney disease (p < 0.001) and heart failure (p = 0.001). Mortality was highest in patients aged 80+(1.07%, p < .001), with yearly rates peaking at 0.14% in 2012.

For left atrial appendage occlusion (LAAO), total lab time and nonprocedure time were significantly lower with moderate sedation (MS) compared to the general anesthesia (GA) with increased use of 4-dimensional echocardiography with no difference in clinical outcomes.

The positive F wave in lead V1 changed during entrainment from the right atrial appendage (RAA) during typical atrial flutter (AFL). The 3-dimensional (3D) electroanatomical map during entrainment from the RAA revealed an area of antidromic capture around the RAA, which was the only difference from the 3D electroanatomical map of typical AFL, proving that the activation around the RAA is responsible for the generation of the positive F wave in lead V1 of typical AFL.
