Abstract:

The purposes of this study were to determine the effects of static and hold-relax stretching on hamstring range of motion and to examine the reliability of the FlexAbility LE1000 compared with the goniometrically measured active knee-extension test. Forty-two participants (18–25 years old) were assigned to either a control, static, or hold-relax training group. Participants were stretched four times a week over a 6-week period, with four 30-s stretches per session using a straight-leg-raise method on the FlexAbility LE1000. It was determined that both static and hold-relax techniques significantly improved hamstring flexibility (ISLR: +33.08° ± 9.08° and +35.17° ± 10.39°, respectively). Participants of both techniques reached a plateau in flexibility improvement between Weeks 4 and 5. Thus, static and hold-relax stretching are equally effective in improving hamstring ROM. The FlexAbility LE1000 and the goniometer were both found to be highly reliable. Therefore, either measurement technique could be used successfully to measure hip-flexion ROM.

Abstract Funding Acknowledgements Type of funding sources: None. Background high power short duration (HPSD) ablation is at least as safe while reducing procedure time than radiofrequency (RF) ablation with lower power in pts undergoing pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF). Purpose: to compare safety and efficacy of 2 different: 1) RF energy set up (FlexAbility: 70W, 41°, 6-10s, 11ml/h vs. TactiCath: 50W, 41°, LSI 5-6, 17ml/h, both Abbott), and 2) ablation strategies (posterior wall isolation (PWI) in addition to PVI vs. PVI) in pts undergoing their first ablation for paroxysmal AF. Methods: since June 2020 pts are prospectively assigned to alternatively undergo their RF catheter ablation with the FlexAbility (v-HPSD) or the TactiCath (LSI-HPSD) catheters (aim 200 pts). In addition, pts were alternatively assigned to PVI + PWI vs. PVI. All procedures were done using a 3D-mapping system (Ensite Precision), the ablation catheter was stabilized with a long sheath (Agilis) and a continuous series of lesions (4mm) were plotted around the PV, at the roof and between the 2 inferior PVs. On the PW, RF lesions were limited to 6s and 5 LSI for the v-HPSD and LSI-HPSD groups. Endoscopy was performed shortly after ablation in all pts and thermal esophageal lesion (TEL) characterized with the Kansas classification. Results: since June 2020 56 pts [61 ± 13 years old, 17 (30%) female, CHA2DS2-Vasc 2.3 ± 1.5, 55 ± 77 left ventricular ejection fraction] underwent v-HPSD (#28) and LSI-HPSD (#28) ablation. In 2/14 (14%) and in 3/15 (20%) pts (v-HPSD and LSI-HPSD groups, respectively) initially assigned to undergo simple PVI, PWI was added due to PW dependent flutter or evidence of pro-arrhythmic slow conduction on the PW. A shorter RF time to achieve PVI (17 ± 3 vs. 25 ± 6 min; P<.0001) was found for the v-HPSD group, although acute reconnection were numerically higher (9 vs. 4) and procedural time did not differ (32 ± 8 vs. 35 ± 9 min). Whenever attempted, PWI (#16 for each v-HPSD and LSI-HPSD group) was always successful. When v-HPSD and LSI-HPSD group were compared, no differences were found in RF and procedure time both at the roof (2.3 ± 0.9 vs. 2.7 ± 1.1 min and 3 ± 1.4 vs. 3.4 ± 1 min, respectively) and between the 2 inferior PVs (2.6 ± 0.6 vs. 2.9 ± 0.7 min and 4.3 ± 1.9 vs. 3.8 ± 1.2 min, respectively). Total RF (19.7 ± 4.5 vs. 28.5 ± 6.6 min, P<.0001) was shorted in the v-HPSD, but X-Ray (1.4 ± 0.7 vs. 1.2 ± 0.8 min) and total procedural time (102 ± 17 vs. 110 ± 20 min) did not differ. Rate of TELs was not different and found in 18% (#5: 4 I, 1 IIA) and 14% (all IIA) pts assigned to v-HPSD and LSI-HPSD respectively. A numerically higher number of TELs (6 vs. 3) was seen when PWI was pursued, although this did not prolong total RF and procedure time. Conclusion: a shorter RF time is associated with v-HPSD vs. LSI-HPSD strategy, although procedural time did not differ. TELs are a relative rare finding, and only numerically higher when isolation of the PW is pursued in addition to PV isolation.

Abstract:

Abstract Background wide antral pulmonary vein (PV) catheter ablation (CA) in patients with atrial fibrillation (AF) is safe and effective when permanent trans-mural lesions are achieved without causing harm to surrounding anatomical structures. Atrio-esophageal fistula, due to its high mortality, is the most dreadful complication related to CA for AF, therefore alternative radiofrequency (RF) approaches to reduce or eliminate this complication are currently studied. The shallower but wider lesions of high power short duration (HPSD) ablation might represent a safe alternative. Purpose to compare the rate of thermal esophageal lesions in patients with paroxysmal and persistent AF undergoing CA assigned to the 2 different RF modality. Methods one-hundred patients with paroxysmal and 100 with persistent AF will be alternatively assigned to undergo CA with the FlexAbility™ (HPSD group: 70W, 41°, 8 seconds) or the TactiCath™ (LSI-group: 35W, 41°, LSI: 5-5.5 posterior wall, up to 6 anywhere else) catheter. A 3-D mapping system, a steerable sheath and adenosine-test (30mg) were used in all patients. Posterior wall (PW) isolation in addition to PV isolation was performed in all, and patients with persistent AF were additionally treated with mitral and cavotricuspid isthmus ablation. Insertion of an esophageal probe was always attempted, and all patients underwent upper endoscopy 24 to 48 hours after CA. Results between June and October 2019, 71 patients (68 ± 10 years old, 32 (45%) female, 44 (60%) paroxysmal AF, AF duration 58 ± 81 months) were alternatively assigned to HPSD (36, 51%) or LSI-guided (35, 49%) ablation. No differences in clinical characteristics were found between groups. After 45 ± 18min and 30 ± 14 min of procedural and RF time, all PVs were isolated, and all spontaneous and adenosine-induced reconnections treated. Successful PW isolation was achieved with an additional 8 ± 3 and 7 ± 3 min of procedural and RF time. When HPSD and LSI-guided groups are compared, a similar rate of clinically non-relevant and self-healing thermal lesions at endoscopy was found (10, 27.8% vs. 10, 28.6%). Independent of the treatment group, a higher peak temperature identified patients with esophageal lesions (43.2° vs. 42°; P=.0065). A peak temperature value of 43.1° best identify patients most likely to develop thermal lesions (AUC 0.71, SE 84%, SP 39%). Interestingly, none of the 11 patients in whom esophageal probe insertion was not possible or attempted developed thermal lesions in comparison to 20 (33%) patients who underwent esophageal temperature monitoring (P=.0046). Conclusions: no difference in thermal induced esophageal lesions were found when the two different RF approach (HPSD vs. LSI guided) were compared. Interestingly, lack of temperature monitoring with an esophageal probe is associated with no thermal lesions at endoscopy.

Abstract:

Abstract Background permanent trans-mural lesions not affecting surrounding anatomical structures is the goal of safe and effective wide antral pulmonary vein (PV) isolation in patients with paroxysmal and persistent atrial fibrillation (AF) undergoing catheter ablation (CA). Time, energy and contact force are parameters related to lesion goodness and incorporated in a complex formula (i.e. the lesion index, LSI™, Abbott). This parameter is emerging as the gold standard for PV isolation. Recently, the shallower but wider lesions created by high power short duration (HPSD) ablation has came to attention. Purpose to compare acute reconnection rate, procedural parameters, and complication rates in patients with paroxysmal or persistent AF undergoing CA. Methods one-hundred patients with paroxysmal and 100 with persistent AF will be alternatively assigned to undergo PV isolation with the FlexAbility™ (HPSD group, 70W, 41°, 8 seconds) or the TactiCath™ (LSI-group: 35W, 41°, LSI: 5-5.5 posterior wall, up to ≥6 anywhere else) catheter. A 3-D mapping system (Ensite Precision™) and a steerable sheath (Agilis™, both Abbott) were always used. Adenosine (30mg) is given after PV isolation and ≥ 20 minutes waiting time. Posterior wall isolation was added in all, and patients with persistent AF were additionally treated with mitral and cavotricuspid isthmus ablation. Results: between June and October 2019, 71 patients (68 ± 10 years old, 32 (45%) female, 44 (60%) paroxysmal AF, AF duration 58 ± 81 months) were alternatively assigned to HPSD (36, 51%) or LSI-guided (35, 49%) ablation. No difference in clinical characteristics was found between groups. After 44 ± 18 and 30 ± 14min of procedural and RF time, all PVs were isolated, and all 17 (24%) reconnections treated with an additional 4 ± 3 and 3 ± 2min, respectively. In 8 ± 3 and 7 ± 3 min of procedural and RF time, the PW was successfully isolated in all. PV isolation (34 ± 12min vs. 56 ± 16min; P<.0001), RF (18 ± 5min vs. 41 ± 9min; P<.0001), and total procedural (138 ± 34min vs. 162 ± 34min; P=.0026) time were shorter in the HPSD group. X-Ray time and effective dose did not differ. A similar rate of acute reconnections (9, 25% vs. 8 23%) was found when HPSD and LSI were compared. A higher, although statistically not significant, number of steam pops was observed in the HPSD (14, 39%) vs. LSI (8, 23%) group, possibly related to the higher incidence of moderate pericardial effusion (>0.5mm, <20mm) found the day following the ablation (10, 28% vs. 2, 6%; P=.0238). No further complications related to CA were detected. Conclusions in patients with paroxysmal and persistent AF undergoing their first CA, HPSD ablation is faster than an LSI-guided approach. Acute efficacy (reconnection rate) is similar. Although a higher rate of haemodynamically non-relevant pericardial effusions were seen in the HPSD group, these were all treated medically and the general safety profile of this approach is excellent and comparable to LSI ablation.

Abstract:

The main purpose of this study was to compare the acute effects of static and dynamic stretching in the warm-up, on hamstring flexibility using a reliable set-up for measurement. Static and dynamic flexibility was measured using five modifications of the Straight Leg Raise (SLR) test to measure hip flexion range of motion (ROM). In the first part of the study (n = 33) hamstring flexibility was measured using a Static-passive, Static-active, Dynamic-supine and Dynamic-standing tests. The results of this study were used to calculate reliability statistics and to compare the various static and dynamic flexibility tests. There was a significant difference between Static-passive (SPH) and the Dynamic-supine (DSUH) tests (p less than .05). This was followed by an intervention study (n = 12) where participants were randomly assigned to three intervention treatments of 225 seconds on separate days: No stretching (Treatment I), Static stretching (Treatment 2) and Dynamic stretching (Treatment 3) in a cross-over study design. Static stretching had no impact on dynamic hamstring flexibility; however, dynamic stretching improved dynamic flexibility while simultaneously increasing static flexibility. This has implications for the specificity of stretching in sport.
