WebPhrenic nerve function was monitored in 100% of cases using diaphragmatic pacing. Pulmonary vein potentials were visualized in 59.8% of PVs during the ablation. The number of freeze applications per vein was 1.84 ± 1.07, mean time to effect (TTE) was 54.4 ± 37.2 s, and mean minimal temperature (minT) of the balloon was −48.95 ± 6.6 °C. WebPulmonary venous flow patterns provide unique and ancillary information for evaluating left ventricular diastolic function, measuring left ventricular filling pressure, assessing MR severity, differentiating constrictive pericarditis from restrictive cardiomyopathies, and identifying pulmonary vein stenosis after radiofrequency ablation of AFib. 46 TTE can …
