Background: Irrigated radiofrequency ablation with half-normal saline can potentially increase lesion size but may increase the risk of steam pops with the risk of emboli or perforation. We hypothesized that pops would be preceded by intracardiac echocardiography (ICE) findings as well as a large impedance fall.

Methods: In 100 consecutive patients undergoing endocardial ventricular arrhythmia radiofrequency ablation with half-normal saline, we attempted to observe the ablation site with ICE. Radiofrequency ablation power was titrated to a 15 to 20 Ohm impedance fall and could be adjusted for tissue whitening and increasing bubble formation on ICE. Steam pops were defined as audible or a sudden explosion of microbubbles on ICE.

Results: Of 2190 ablation applications in 100 patients (82% cardiomyopathy, 50% sustained ventricular tachycardia), pops occurred during 43 (2.0%) applications. Sites with pops had greater impedance decreases of 18 [14, 21]% versus 13 [10, 17]% (P<0.001). ICE visualized 1308 (59.7%) radiofrequency sites, and fewer pops occurred when ICE visualized the radiofrequency ablation site (1.4%) compared with without ICE visualization (2.8%; P=0.016). Of the 18 ICE-visible pops, 7 (39%) were silent but recognized as an explosion of bubbles on ICE. With ICE, 89% of pops were preceded by either tissue whitening or a sudden increase in bubbles. In a multivariable model, tissue whitening and a sudden increase in bubbles were associated with steam pops (odds ratio, 7.186; P=0.004, and odds ratio, 29.93; P<0.001, respectively), independent of impedance fall and power. There were no pericardial effusions or embolic events with steam pops.

Conclusions: Steam pops occurred in 2% of half-normal saline radiofrequency applications titrated to an impedance fall and are likely under-recognized without ICE. On ICE, steam pops are usually preceded by tissue whitening or a sudden increase in bubble formation, which can potentially be used to adjust radiofrequency application to help reduce pops.

背景:使用半生理盐水冲洗射频消融术有可能增大病灶面积,但可能会增加蒸汽爆裂的风险以及栓塞或穿孔的风险。我们假设,爆裂之前会有心内超声心动图(ICE)检查结果以及阻抗大幅下降:方法:在 100 例连续接受心内膜室性心律失常射频消融术的患者中,我们尝试用 ICE 观察消融部位。射频消融功率被调节到 15 到 20 欧姆的阻抗值,并可根据组织变白和 ICE 上气泡形成增加的情况进行调整。蒸汽爆裂是指在 ICE 上可听到或突然爆发的微气泡:在 100 名患者(82% 患有心肌病,50% 患有持续性室性心动过速)的 2190 次消融治疗中,有 43 次(2.0%)发生了爆裂。出现爆裂的部位阻抗下降幅度更大,分别为 18 [14, 21]% 和 13 [10, 17]% (PP=0.016)。在 18 个 ICE 可见的爆裂声中,有 7 个(39%)是无声的,但在 ICE 上可识别为气泡爆炸。在使用 ICE 时,89% 的爆裂前会出现组织变白或气泡突然增加。在多变量模型中,组织变白和气泡突然增加与蒸汽爆裂有关(几率比为 7.186;P=0.004,几率比为 29.93;PC 结论):在阻抗下降的半正常生理盐水射频应用中,有 2% 出现了蒸汽爆裂,如果没有 ICE,这种情况很可能没有被充分认识到。在使用 ICE 时,蒸汽爆裂之前通常会出现组织变白或气泡形成突然增加的现象,这有可能用来调整射频应用以帮助减少爆裂。

Background: Endocardial catheter-based pulsed field ablation (PFA) of the ventricular myocardium is promising. However, little is known about PFA's ability to target intracavitary structures, epicardium, and ways to achieve transmural lesions across thick ventricular tissue.

Methods: A lattice-tip catheter was used to deliver biphasic monopolar PFA to swine ventricles under general anesthesia, with electroanatomical mapping, fluoroscopy and intracardiac echocardiography guidance. We conducted experiments to assess the feasibility and safety of repetitive monopolar PFA applications to ablate (1) intracavitary papillary muscles and moderator bands, (2) epicardial targets, and (3) bipolar PFA for midmyocardial targets in the interventricular septum and left ventricular free wall.

Results: (1) Papillary muscles (n=13) were successfully ablated and then evaluated at 2, 7, and 21 days. Nine lesions with stable contact measured 18.3±2.4 mm long, 15.3±1.5 mm wide, and 5.8±1.0 mm deep at 2 days. Chronic lesions demonstrated preserved chordae without mitral regurgitation. Two targeted moderator bands were transmurally ablated without structural disruption. (2) Transatrial saline/carbon dioxide assisted epicardial access was obtained successfully and epicardial monopolar lesions had a mean length, width, and depth of 30.4±4.2, 23.5±4.1, and 9.1±1.9 mm, respectively. (3) Bipolar PFA lesions were delivered across the septum (n=11) and the left ventricular free wall (n=7). Twelve completed bipolar lesions had a mean length, width, and depth of 29.6±5.5, 21.0±7.3, and 14.3±4.7 mm, respectively. Chronically, these lesions demonstrated uniform fibrotic changes without tissue disruption. Bipolar lesions were significantly deeper than the monopolar epicardial lesions.

Conclusions: This in vivo evaluation demonstrates that PFA can successfully ablate intracavitary structures and create deep epicardial lesions and transmural left ventricular lesions.

背景:- 基于心内膜导管的心室心肌脉冲场消融术(PFA)前景广阔。然而,人们对 PFA 针对腔内结构、心外膜的能力以及在厚心室组织中实现跨膜病变的方法知之甚少。方法:- 在全身麻醉、电解剖图、透视和心内超声心动图(ICE)引导下,使用格状尖端导管将双相单极 PFA 输送到猪心室。我们进行了实验,以评估重复应用单极 PFA 消融以下目标的可行性和安全性:i)腔内乳头肌和节律带;ii)心外膜目标;iii)用于室间隔和左心室游离壁的心肌中层目标的双极 PFA。结果如下- i) 成功消融了乳头肌(n=13),然后在 2、7 和 21 天进行了评估。九个接触稳定的病灶在 2 天时的长度为 18.3≥2.4毫米,宽度为 15.3≥1.5毫米,深度为 5.8≥1.0毫米。慢性病损显示腱膜保留,无二尖瓣反流。ii) 经心房生理盐水/二氧化碳辅助心外膜入路成功,心外膜单极病变的平均长度、宽度和深度分别为 30.4≥4.2 毫米、23.5≥4.1 毫米和 9.1≥1.9 毫米。12 个完成的双极病变的平均长度、宽度和深度分别为 29.6≥5.5毫米、21.0≥7.3 毫米和 14.3≥4.7毫米。长期来看,这些病变显示出均匀的纤维化变化,但没有组织破坏。双极病变明显深于单极心外膜病变。结论- 这项活体评估表明,PFA 能成功消融腔内结构,形成深心外膜病变和跨壁左心室病变。

BACKGROUNDSacubitril/valsartan (Sac/Val) is superior to angiotensin-converting enzyme inhibitors in reducing the risk of heart failure hospitalization and cardiovascular death, but its mechanistic data on myocardial scar after myocardial infarction (MI) are lacking. The objective of this work was to assess the effects of Sac/Val on inflammation, fibrosis, electrophysiological properties, and ventricular tachycardia inducibility in post-MI scar remodeling in swine.METHODSAfter MI, 22 pigs were randomized to receive β-blocker (BB; control, n=8) or BB+Sac/Val (Sac/Val, n=9). The systemic immune response was monitored. Cardiac magnetic resonance data were acquired at 2-day and 29-day post MI to assess ventricular remodeling. Programmed electrical stimulation and high-density mapping were performed at 30-day post MI to assess ventricular tachycardia inducibility. Myocardial samples were collected for histological analysis.RESULTSCompared with BB, BB+Sac/Val reduced acute circulating leukocytes (P=0.009) and interleukin-12 levels (P=0.024) at 2-day post MI, decreased C-C chemokine receptor type 2 expression in monocytes (P=0.047) at 15-day post MI, and reduced scar mass (P=0.046) and border zone mass (P=0.043). It also lowered the number and mass of border zone corridors (P=0.020 and P=0.05, respectively), scar collagen I content (P=0.049), and collagen I/III ratio (P=0.040). Sac/Val reduced ventricular tachycardia inducibility (P=0.026) and the number of deceleration zones (P=0.016).CONCLUSIONSAfter MI, compared with BB, BB+Sac/Val was associated with reduced acute systemic inflammatory markers, reduced total scar and border zone mass on late gadolinium-enhanced magnetic resonance imaging, and lower ventricular tachycardia inducibility.
背景萨库比特利/缬沙坦(Sac/Val)在降低心力衰竭住院和心血管死亡风险方面优于血管紧张素转换酶抑制剂,但其对心肌梗死(MI)后心肌瘢痕的机理数据尚缺。本研究的目的是评估 Sac/Val 对猪心肌梗死后瘢痕重塑中的炎症、纤维化、电生理特性和室性心动过速诱导性的影响。方法心肌梗死后,22 头猪随机接受 β-受体阻滞剂(BB;对照组,n=8)或 BB+Sac/Val (Sac/Val,n=9)。监测全身免疫反应。在心肌梗死后 2 天和 29 天采集心脏磁共振数据,以评估心室重塑情况。在心肌梗死后30天进行编程电刺激和高密度绘图,以评估室性心动过速的诱导性。结果与 BB 相比,BB+Sac/Val 降低了急性循环白细胞(P=0.009)和急性心肌梗死后 2 天的白细胞介素-12 水平(P=0.024),降低了急性心肌梗死后 15 天单核细胞中 C-C 趋化因子受体 2 型的表达(P=0.047),减少了瘢痕质量(P=0.046)和边界区质量(P=0.043)。它还降低了边界区走廊的数量和质量(分别为 P=0.020 和 P=0.05)、瘢痕胶原 I 含量(P=0.049)和胶原 I/III 比值(P=0.040)。结论心肌梗死后,与 BB 相比,BB+Sac/Val 与急性全身炎症标志物减少、晚期钆增强磁共振成像总瘢痕和边界区肿块减少以及室性心动过速诱发率降低有关。

BACKGROUNDWe previously presented the safety and early efficacy of inspIRE study (Pulsed-Field Ablation (PFA) System for the Treatment of Paroxysmal Atrial Fibrillation by Irreversible Electroporation). With the study's conclusion, we report the outcomes of the full pivotal study cohort, with an additional analysis of predictors of success.METHODSInspIRE was a prospective, multicenter, single-arm clinical trial of drug-refractory paroxysmal atrial fibrillation. Pulmonary vein isolation was performed with a variable-loop circular catheter integrated with a 3-dimensional mapping system. Follow-up with 24-hour Holter was at 3, 6, and 12 months, as well as remote rhythm monitoring: weekly from 3 to 5 months, monthly from 6 to 12 months, and for symptoms. The primary effectiveness end point (PEE) was acute pulmonary vein isolation plus freedom from any atrial arrhythmia at 12 months. Additional subanalyses report predictors of PEE success.RESULTSThe patient cohort included 186 patients: aged 59±10 years, female 30%, and CHA2DS2-VASc 1.3±1.2. The previously reported primary adverse event rate was 0%. One serious procedure-related adverse event, urinary retention, was reported. The PEE was achieved in 75.6% (95% CI, 69.5%-81.8%). The clinical success of freedom from symptomatic recurrence was 81.7% (95% CI, 76.1%-87.2%). Simulating a monitoring method used in standard real-world practice (without protocol-driven remote rhythm monitoring), this translates to a freedom from all and symptomatic recurrence of 85.8% (95% CI, 80.8%-90.9%) or 94.0% (95% CI, 90.6%-97.5%), respectively. Multivariate analyses revealed that left ventricular ejection fraction ≥60% (adjusted odds ratio, 0.30) and patients receiving ≥48 PFA applications (adjusted odds ratio, 0.28) were independent predictors of PEE success.

背景我们曾介绍过 inspIRE 研究(通过不可逆电穿孔治疗阵发性房颤的脉冲场消融 (PFA) 系统)的安全性和早期疗效。随着研究的结束,我们报告了全部关键研究队列的结果,并对成功预测因素进行了额外分析。方法InspIRE 是一项针对药物难治性阵发性房颤的前瞻性、多中心、单臂临床试验。肺静脉隔绝术是通过集成了三维绘图系统的可变环形导管进行的。24小时Holter随访时间为3、6和12个月,以及远程心律监测:3至5个月每周一次,6至12个月每月一次,并对症状进行监测。主要疗效终点(PEE)为急性肺静脉隔绝术后 12 个月无任何房性心律失常。其他子分析报告了 PEE 成功的预测因素。结果患者队列包括 186 名患者:年龄为 59±10 岁,女性占 30%,CHA2DS2-VASc 为 1.3±1.2。之前报告的主要不良事件发生率为 0%。报告了一起严重的手术相关不良事件,即尿潴留。75.6%的患者实现了PEE(95% CI,69.5%-81.8%)。无症状复发的临床成功率为 81.7%(95% CI,76.1%-87.2%)。模拟真实世界标准实践中使用的监测方法(无协议驱动的远程心律监测),这意味着无症状复发率和无症状复发率分别为 85.8%(95% CI,80.8%-90.9%)或 94.0%(95% CI,90.6%-97.5%)。多变量分析显示,左心室射血分数≥60%(调整后的几率比为0.30)和患者接受了≥48次PFA应用(调整后的几率比为0.28)是PEE成功的独立预测因素。此外,接受 PFA 应用次数≥12 次/静脉的患者的 PEE 成功率为 79.2%,而接受 PFA 应用次数较少的患者的成功率为 57.1%。PFA应用的最佳次数(总共≥48次或每条静脉≥12次)可提高1年成功率≈80%.REGISTRATIONURL: https://www.clinicaltrials.gov; Unique identifier:NCT04524364。

With the study's conclusion, we report the outcomes of the full pivotal study cohort, with an additional analysis of predictors of success.\u0000\u0000\u0000METHODS\u0000InspIRE was a prospective, multicenter, single-arm clinical trial of drug-refractory paroxysmal atrial fibrillation. Pulmonary vein isolation was performed with a variable-loop circular catheter integrated with a 3-dimensional mapping system. Follow-up with 24-hour Holter was at 3, 6, and 12 months, as well as remote rhythm monitoring: weekly from 3 to 5 months, monthly from 6 to 12 months, and for symptoms. The primary effectiveness end point (PEE) was acute pulmonary vein isolation plus freedom from any atrial arrhythmia at 12 months. Additional subanalyses report predictors of PEE success.\u0000\u0000\u0000RESULTS\u0000The patient cohort included 186 patients: aged 59±10 years, female 30%, and CHA2DS2-VASc 1.3±1.2. The previously reported primary adverse event rate was 0%. One serious procedure-related adverse event, urinary retention, was reported. The PEE was achieved in 75.6% (95% CI, 69.5%-81.8%). The clinical success of freedom from symptomatic recurrence was 81.7% (95% CI, 76.1%-87.2%). Simulating a monitoring method used in standard real-world practice (without protocol-driven remote rhythm monitoring), this translates to a freedom from all and symptomatic recurrence of 85.8% (95% CI, 80.8%-90.9%) or 94.0% (95% CI, 90.6%-97.5%), respectively. Multivariate analyses revealed that left ventricular ejection fraction ≥60% (adjusted odds ratio, 0.30) and patients receiving ≥48 PFA applications (adjusted odds ratio, 0.28) were independent predictors of PEE success. Moreover, PEE success was 79.2% in patients who received ≥12 PFA applications/vein compared with 57.1% in patients receiving fewer PFA applications.\u0000\u0000\u0000CONCLUSIONS\u0000The inspIRE study confirms the safety and effectiveness of pulmonary vein isolation using the novel 3-dimensional mapping integrated circular loop catheter.

BACKGROUNDThe risk factor (RF) burden, clinical course, and long-term outcome among patients with atrial fibrillation (AF) aged <65 years is unclear.METHODSAdult (n=67 221; mean age, 72.4±12.3 years; and 45% female) patients with AF evaluated at the University of Pittsburgh Medical Center between January 2010 and December 2019 were studied. Hospital system-wide electronic health records and administrative data were utilized to ascertain RFs, comorbidities, and subsequent hospitalization and cardiac interventions. The association of AF with all-cause mortality among those aged <65 years was analyzed using an internal contemporary cohort of patients without AF (n=918 073).RESULTSNearly one-quarter (n=17 335) of the cohort was aged <65 years (32% female) with considerable cardiovascular RFs (current smoker, 16%; mean body mass index, 33.0±8.3; hypertension, 55%; diabetes, 21%; heart failure, 20%; coronary artery disease, 19%; and prior ischemic stroke, 6%) and comorbidity burden (chronic obstructive pulmonary disease, 11%; obstructive sleep apnea, 18%; and chronic kidney disease, 1.3%). Over mean follow-up of >5 years, 2084 (6.7%, <50 years; 13%, 50-65 years) patients died. The proportion of patients with >1 hospitalization for myocardial infarction, heart failure, and stroke was 1.3%, 4.8%, and 1.1% for those aged <50 years and 2.2%, 7.4%, and 1.1% for the 50- to 65-year subgroup, respectively. Multiple cardiac and noncardiac RFs were associated with increased mortality in younger patients with AF with heart failure and hypertension demonstrating significant age-related interaction (P=0.007 and P=0.013, respectively). Patients with AF aged <65 years experienced significantly worse survival compared with comorbidity-adjusted patients without AF (males aged <50 years and hazard ratio, 1.5 [95% CI, 1.24-1.79]; 50-65 years and hazard ratio, 1.3 [95% CI, 1.26-1.43]; females aged <50 years and hazard ratio, 2.4 [95% CI, 1.82-3.16]; 50-65 years and hazard ratio, 1.7 [95% CI, 1.6-1.92]).CONCLUSIONSPatients with AF aged <65 years have significant comorbidity burden and considerable long-term mortality. They are also at a significantly increased risk of hospitalization for heart failure, stroke, and myocardial infarction. These patients warrant an aggressive focus on RF and comorbidity evaluation and management.
背景心房颤动(AF)患者的风险因素(RF)负担、临床过程和长期预后,年龄在 5 岁以下的患者分别为 1.3%、4.8% 和 1.1%,年龄在 50 至 65 岁的亚组分别为 2.2%、7.4% 和 1.1%,年龄在 50 至 65 岁的患者分别为 2084 人(6.7%)、1 人因心肌梗死、心力衰竭和中风住院。多种心源性和非心源性射频与年轻房颤患者死亡率增加有关,心衰和高血压显示出显著的年龄相关交互作用(分别为 P=0.007 和 P=0.013)。与合并症调整后的无房颤患者相比,年龄小于 65 岁的房颤患者生存率明显降低(男性小于 50 岁,危险比为 1.5 [95% CI, 1.24-1.79];50-65 岁,危险比为 1.3 [95% CI, 1.26-1.结论年龄小于 65 岁的房颤患者具有显著的并发症负担和相当高的长期死亡率。他们因心力衰竭、中风和心肌梗死住院的风险也明显增加。这些患者需要积极重视射频和合并症的评估和管理。
