The very high-power short-duration (vHPSD) temperature-controlled ablation (vHPSD) improves the efficiency of pulmonary vein isolation (PVI) procedures. We evaluated the procedural and 12-months outcomes in atrial fibrillation (AF) patients undergoing PVI by means of vHPSD ablation. In patients with AF or atrial tachyarrythmia (AT) recurrence undergoing a redo procedure the durability of the PVI was investigated.Consecutive paroxysmal/persistent AF patients undergoing PVI with the vHPSD ablation strategy (90 W, for 4 s) were enrolled. The rate of PVI, first-pass isolation, acute reconnection, and procedural complications were evaluated. Follow-up examinations and EKG were scheduled at 3,6, and 12 months. In case of AF/AT recurrence, patients underwent a redo procedure.Overall, 163 AF patients (29 persistent and 134 paroxysmal) were enrolled. The PVI was reached in 100% of patients (88% at the first pass). The rate of acute reconnection was 2%. The radiofrequency, fluoroscopy and procedural times were respectively 5.5 ± 1 min, 9 ± 1 min and 75 ± 20 min. No death, tamponade nor steam pops occurred; however, 5 patients had vascular complications. The 12-months freedom from AF/AT recurrence was 86% in both paroxysmal and persistent patients. Overall, 9 patients underwent a redo procedure, and in 4 all veins were still isolated, whereas in 5 pulmonary vein reconnections were found. The PVI durability was 78%. No overt clinical complications were observed in the follow-up.The vHPSD ablation represents an effective and safe ablation strategy to achieve PVI. The 12-months follow-up showed high freedom from AF/AT recurrence and a good safety profile.
Abstract Data on the horizontal and vertical distribution of diatom species, collected between April 1995 and March 1996 in coastal waters of the Apulian Adriatic Sea are presented. A total number of 120 species belonging to 51 genera were identified. Diatoms were dominant in the major part of the examined samples, constituting up to 90% of the total cell numbers during the spring period.
It Si riportano i primi dati sulla pesca di Xiphias gladius L. effettuata con palamiti di superficie nel Basso Adriatico nell’estate del 1981.
Altri teleostei pelagici catturati sono: Ruvettus pretiosus Cocco, Euthynnus alletteratus ( RAF.), Euthynnus pelamis (L.) e Thunnnus alalunga (BONN.) e i Selaci Prionace glauca (L.) e Lamna nasus (BONN.).
Gli esemplari di Xiphias sono prevalentemente rappresentati da adulti con moda 140-155 cm per la lunghezza totale e moda 29-44 Kg per il peso.
L’esemplare di maggiore mole, Kg 116, presenta una lunghezza totale di 219 cm.
I giovani spada rappresentano il 34% del numero complessivo di Xiphias e solo il 6% del peso del pescato.
Si riportano anche gli indici somatometrici e le relative correlazioni. En Preliminary data on sworld-fish Xiphias gladius L. fishery effected by boulter in the Southern Adriatic Sea in the summer 1981, are reported.
Other pelagic Teleostei captured are: Ruvettus pretiosus Cocco, Euthynnus alletteratus (RAF.) and Selachii: Prionace glauca (L.), Lamna nasus (BONN.)
Prevalently the specimens of Xiphias consist of adults with mode 140-155 cm for total length and mode 29-44 Kg for the weight.
The largest one weights Kg 116 an is 219 c min legth.
Young individuals are 34% of the totale number of Xiphias fished and only 60% of the catch weight.
The somatometric indices and relative correlations are described as well.
Abstract Background The very high-power short-duration (90W for 4 s) temperature-controlled ablation (vHPSD) improves the efficiency of pulmonary vein (PV) isolation procedures. However, atrial fibrillation (AF) recurrences directly related to PV reconnections are still a concern. Purpose The purpose of the current study was to assess PV lesion durability in patients undergoing a reablation procedure. Methods From September 2020 to July 2023, 327 patients with paroxysmal and persistent AF underwent first ablation aiming at PVI using vHPSD. During a mean follow-up of 25±11 months, 48 patients (14.7%) had an AF recurrence. Patients with reablation procedures were retrospectively consented and enrolled. Results Eighteen patients were included in this study. A PV reconnection was observed in 15/72 (21%) PVs, with a mean number of reconnected PV per patient of 0.8 ±0.7. In 7 patients no PV reconnection was observed, one PV reconnected was observed in 9 patients and 2 PVs in 3 patients. A PV reconnection was observed in 8/18 (44%) left superior PV, 1/18 (6%) left inferior PV, 3/18 (17%) right superior PV, and 3/18 (17%) right inferior PV (p=0.03). Conclusions PV isolation performed with vHPSD is highly effective and is associated with a low rate of late PV reconnection. A higher percentage of PV reconnection was observed in the left superior PV.
