Article Synopsis
- During pulsed field ablation (PFA), researchers studied the impact of various parameters like contact force (CF) and number of bursts on lesion size in beating hearts using a specialized catheter in swine.
- The study involved 11 closed-chest swine and tested different levels of CF and burst pulses, measuring lesion size after euthanization with a specific staining technique.
- Results showed that higher CF and more burst pulses significantly increased lesion depth, with a reliable formula predicting lesion size, while impedance decrease and electrode temperature were not effective predictors.
According to Dollo's Law of irreversibility in evolution, a lost structure is usually considered to be unable to reappear in evolution due to the accumulation over time of mutations in the genes required for its formation. Cypriniform fish are a classic model of evolutionary loss because, while they form fully operational teeth in the ventral posterior pharynx, unlike other teleosts, they do not possess oral teeth. Paleontological data show that Cypriniforms, a clade of teleost fish that includes the zebrafish, lost their oral teeth 50 to 100 Mya.

Methods: We conducted a systematic search in MEDLINE and EMBASE to identify studies that reported the outcome of recurrence of AF after CA in obese patients undergoing weight interventions.
