Introduction and objectives

Most of the complications associated with acute and symptomatic bradyarrhythmia (ASB) occur in the time from diagnosis to permanent pacemaker implantation (PPI). We aimed to evaluate the outcomes of an urgent 24/7 PPI service (PPI-24/7) for patients with ASB.

Methods

A total of 664 patients undergoing first-time PPI for ASB were prospectively assessed during 2 periods of identical length (18 months): 341 patients who underwent the procedure during working hours only (PPI-WH), and 323 patients who underwent the procedure after the implementation of the PPI-24/7 service. The primary safety endpoint was established as the cumulative 180-day incidence of complications related to the index arrhythmia and device implant. The primary efficacy endpoint was determined as the average number of hospital stays per patient.

Results

The PPI-24/7 period was associated with a significant shortening of the time from diagnosis to implantation (median [interquartile range]): 3 hours [2-6] vs 16 [5-21]). The cumulative incidence of patients with complications at 180 days was lower in the PPI-24/7 period: 9% vs 17% (adjusted odds ratio, 0.5; P = .002), due to a significant reduction in preimplant complications: 2.5% vs 12% (P < .001). The average number of hospital stays was reduced by 2 per patient in the PPI-24/7 period (nonparametric P < .001). PPI-24/7 implants performed outside working hours (n = 178) were safe, with a 180-day cumulative incidence in procedure-related complications of 3.9%.

Conclusions

Among patients with ASB, PPI-24/7 was associated with a significant reduction in patient morbidity and efficient hospital resource use.

导言和目的急性症状性心动过缓（ASB）的相关并发症大多发生在从诊断到永久起搏器植入（PPI）的过程中。我们的目的是评估为 ASB 患者提供的全天候紧急 PPI 服务（PPI-24/7）的效果。方法在两个相同时间段（18 个月）内对 664 名因 ASB 首次接受 PPI 的患者进行了前瞻性评估：在两个相同的时间段（18 个月）内，共对 664 名首次接受 PPI 治疗的 ASB 患者进行了前瞻性评估：341 名患者仅在工作时间接受治疗（PPI-WH），323 名患者在实施 PPI-24/7 服务后接受治疗。主要安全性终点确定为 180 天内与指数心律失常和设备植入相关的并发症累积发生率。PPI-24/7服务期显著缩短了从诊断到植入的时间（中位数[四分位间范围]：3小时[2-6小时]对16小时）：3小时 [2-6] vs 16 [5-21]）。在 PPI-24/7 期间，患者在 180 天内出现并发症的累计发生率较低：9% vs 17%（调整后的几率比，0.5；P = .002），这是因为植入前并发症显著减少：2.5%对12%（P = .001）。在 PPI-24/7 期间，每位患者的平均住院次数减少了 2 次（非参数 P < .001）。在工作时间以外进行的 PPI-24/7 植入手术（n = 178）是安全的，180 天内手术相关并发症的累积发生率为 3.9%。

Introduction and objectives

Diffuse homogeneous hypoechoic leaflet thickening, with a wavy leaflet motion documented by transesophageal echocardiography (TEE), has been described in some cases of prosthetic valve endocarditis (PVE) involving aortic bioprosthesis (AoBio-PVE). This echocardiographic finding has been termed valvulitis. We aimed to estimate the prevalence of valvulitis, precisely describe its echocardiographic characteristics, and determine their clinical significance in patients with AoBio-PVE.

Methods

From 2011 to 2022, 388 consecutive patients with infective endocarditis (IE) admitted to a tertiary care hospital were prospectively included in a multipurpose database. For this study, all patients with AoBio-PVE (n = 86) were selected, and their TEE images were thoroughly evaluated by 3 independent cardiologists to identify all cases of valvulitis.

Results

The prevalence of isolated valvulitis was 12.8%, and 20.9% of patients had valvulitis accompanied by other classic echocardiographic findings of IE. A total of 9 out of 11 patients with isolated valvulitis had significant valve stenosis, whereas significant aortic valve regurgitation was documented in only 1 patient. Compared with the other patients with AoBio-PVE, cardiac surgery was less frequently performed in patients with isolated valvulitis (27.3% vs 62.7%, P = .017). In 4 out of 5 patients with valve stenosis who did not undergo surgery but underwent follow-up TEE, valve gradients significantly improved with appropriate antibiotic therapy.

Conclusions

Valvulitis can be the only echocardiographic finding in infected AoBio and needs to be identified by imaging specialists for early diagnosis. However, this entity is a diagnostic challenge and additional imaging techniques might be required to confirm the diagnosis. Larger series are needed.

导言和目的经食道超声心动图（TEE）显示，一些涉及主动脉生物假体（AoBio-PVE）的人工瓣膜心内膜炎（PVE）病例出现弥漫性同质低回声瓣叶增厚，并伴有波浪形瓣叶运动。这种超声心动图检查结果被称为瓣膜炎。我们旨在估算瓣膜炎的患病率，精确描述其超声心动图特征，并确定其在 AoBio-PVE 患者中的临床意义。结果孤立性瓣膜炎的发病率为12.8%，20.9%的患者瓣膜炎伴有其他典型的IE超声心动图检查结果。在11名孤立性瓣膜炎患者中，共有9名患者有明显的瓣膜狭窄，而只有1名患者有明显的主动脉瓣反流。与其他患有 AoBio-PVE 的患者相比，孤立性瓣膜炎患者接受心脏手术的比例较低（27.3% 对 62.7%，P = .017）。结论瓣膜炎可能是感染性 AoBio 的唯一超声心动图检查结果，需要由影像学专家识别以进行早期诊断。然而，这种疾病在诊断上是一个挑战，可能需要额外的成像技术来确诊。需要更大规模的系列研究。

Introduction and objectives

Stroke and bleeding risks in atrial fibrillation (AF) are often assessed at baseline to predict outcomes years later. We investigated whether dynamic changes in CHA₂DS₂-VASc and HAS-BLED scores over time modify risk prediction.

Methods

We included patients with AF who were stable while taking vitamin K antagonists. During a 6-year follow-up, all ischemic strokes/transient ischemic attacks (TIAs) and major bleeding events were recorded. CHA₂DS₂-VASc and HAS-BLED were recalculated every 2-years and tested for clinical outcomes at 2-year periods.

Results

We included 1361 patients (mean CHA₂DS₂-VASc and HAS-BLED 4.0 ± 1.7 and 2.9 ± 1.2). During the follow-up, 156 (11.5%) patients had an ischemic stroke/TIA and 269 (19.8%) had a major bleeding event. Compared with the baseline CHA₂DS₂-VASc, the CHA₂DS₂-VASc recalculated at 2 years had higher predictive ability for ischemic stroke/TIA during the period from 2 to 4 years. Integrated discrimination improvement (IDI) and net reclassification improvement (NRI) showed improvements in sensitivity and better reclassification. The CHA₂DS₂-VASc recalculated at 4 years had better predictive performance than the baseline CHA₂DS₂-VASc during the period from 4 to 6 years, with an improvement in IDI and an enhancement of the reclassification. The recalculated HAS-BLED at 2-years had higher predictive ability than the baseline score for major bleeding during the period from 2 to 4 years, with significant improvements in sensitivity and reclassification. A slight enhancement in sensitivity was observed with the HAS-BLED score recalculated at 4 years compared with the baseline score.

Conclusions

In AF patients, stroke and bleeding risks are dynamic and change over time. The CHA₂DS₂-VASc and HAS-BLED scores should be regularly reassessed, particularly for accurate stroke risk prediction.

导言和目的心房颤动（AF）的卒中和出血风险通常在基线时进行评估，以预测数年后的结果。我们研究了 CHA2DS2-VASc 和 HAS-BLED 评分随着时间推移的动态变化是否会改变风险预测。在为期 6 年的随访中，记录了所有缺血性脑卒中/短暂性脑缺血发作（TIA）和大出血事件。每两年重新计算一次 CHA2DS2-VASc 和 HAS-BLED，并在两年期间检测临床结果。随访期间，156 名患者（11.5%）发生了缺血性中风/TIA，269 名患者（19.8%）发生了大出血。与基线 CHA2DS2-VASc 相比，在 2 年时重新计算的 CHA2DS2-VASc 对 2 至 4 年期间缺血性中风/TIA 的预测能力更高。综合辨别改进（IDI）和净再分类改进（NRI）显示灵敏度有所提高，再分类效果更好。与基线 CHA2DS2-VASc 相比，4 年后重新计算的 CHA2DS2-VASc 在 4 至 6 年期间具有更好的预测性能，IDI 有所提高，重新分类能力也有所增强。在 2 至 4 年期间，重新计算的 2 年期 HAS-BLED 对大出血的预测能力高于基线评分，灵敏度和再分类能力显著提高。与基线评分相比，4 年后重新计算的 HAS-BLED 评分的灵敏度略有提高。应定期重新评估 CHA2DS2-VASc 和 HAS-BLED 评分，尤其是为了准确预测卒中风险。

Introduction and objectives

There is limited evidence to identify the most accurate method for measuring the mitral valve area (MVA) after percutaneous edge-to-edge mitral repair. Our objective was to evaluate the optimal method in this context and its correlation with the mean transmitral gradient.

Methods

A registry of patients undergoing percutaneous mitral repair was conducted, analyzing different methods of measuring MVA and their correlation with the mean gradient.

Results

We analyzed data from 167 patients. The mean age was 76 ± 10.3 years, 54% were men, and 46% were women. Etiology was degenerative in 45%, functional in 39%, and mixed in 16%. Postclip MVA measurements were 1.89 ± 0.60 cm² using pressure half-time (PHT), 2.87 ± 0.83 cm² using 3D planimetry, and the mean gradient was 3 ± 1.19 mmHg. MVA using 3D planimetry showed a stronger correlation with the mean gradient (r = 0.46, P < .001) than MVA obtained by PHT (r = 0.19, P = .048). Interobserver agreement was also higher with 3D planimetry than with PHT (intraclass correlation coefficient of 0.90 vs 0.81 and variation coefficient of 9.6 vs 19.7%, respectively).

Conclusions

Our study demonstrates that the PHT method significantly underestimates MVA after clip implantation compared with direct measurement using transesophageal 3D planimetry. The latter method also correlates better with postimplantation gradients and has less interobserver variability. These results suggest that 3D planimetry is a more appropriate method for assessing postclip mitral stenosis.

引言和目的目前，确定经皮二尖瓣边缘对边缘修复术后测量二尖瓣面积（MVA）最准确方法的证据有限。我们的目的是评估在这种情况下的最佳方法及其与平均二尖瓣传导阶差的相关性。方法对接受经皮二尖瓣修复术的患者进行登记，分析测量二尖瓣瓣口面积的不同方法及其与平均阶差的相关性。平均年龄为 76 ± 10.3 岁，54% 为男性，46% 为女性。病因为退行性病变的占 45%，功能性病变的占 39%，混合性病变的占 16%。使用压力半定时法（PHT）测量的夹板后MVA为（1.89 ± 0.60）平方厘米，使用三维平面测量法测量的MVA为（2.87 ± 0.83）平方厘米，平均梯度为（3 ± 1.19）毫米汞柱。使用三维平面测量法获得的 MVA 与平均阶差的相关性（r = 0.46，P <.001）高于 PHT 获得的 MVA（r = 0.19，P = .048）。结论我们的研究表明，与使用经食道三维平面测量法直接测量相比，PHT 法明显低估了夹片植入后的 MVA。后者与植入后梯度的相关性更好，观察者之间的变异性也更小。这些结果表明，三维平面测量法是评估夹片植入后二尖瓣狭窄的更合适的方法。
