Artificial intelligence (AI) can augment coronary angiography images to enhance interpretation. We compared two blinded operators' interpretation of chronic total occlusion (CTO) angiograms obtained for retrograde percutaneous coronary intervention (PCI) standard vs. AI-enhanced (AngioWave, Concord, MA) images and assessed the association with septal collateral crossing success. We reviewed 50 retrograde CTO PCI angiograms. The most common (83.7%) target vessel was the right coronary artery and target CTOs had high complexity with high rates of proximal cap ambiguity (55.3%), blunt or no stump (79.2%), moderate or severe calcification (50.0%) and high J-CTO scores (2.96 ± 0.93). Retrograde was the first crossing strategy in 44.0% of lesions and was successful in 80%. Operators assigned lower frequency of corkscrew bends (10.2% vs 20.6%, p=0.035) and septal collateral tortuosity (31.7% vs 51.5%, p=0.004) and higher frequency of CC2 collateral size (6.5% vs 0.0%, p=0.007) to AI-enhanced compared with standard angiograms. The aggregate predicted likelihood of crossing (85% vs 70%, p<0.001, Wilcoxon test: p<0.001) and ease of interpretation (9.00 vs 7.00, p<0.001) were higher in the AI-enhanced angiograms. There was no difference in predictive performance for crossing success in the two groups (AUCAI-enhanced = 0.74 and AUCstandard = 0.73, De Long test: p=0.856). AI-enhanced angiograms were assigned a median 10.7% higher predicted likelihood of success. Compared with standard angiograms, AI-enhanced angiograms allow easier interpretation of angiograms and have similar predictive performance for collateral crossing despite showing lower collateral complexity.
人工智能(AI)可以增强冠状动脉造影图像以增强解释。我们比较了两名盲法操作人员对逆行经皮冠状动脉介入治疗(PCI)标准和人工智能增强(AngioWave, Concord, MA)图像获得的慢性全闭塞(CTO)血管造影的解释,并评估了与间隔侧支穿越成功的关系。我们回顾了50张逆行CTO PCI血管造影。最常见的靶血管为右冠状动脉(83.7%),靶血管复杂性高,近端冠状动脉模糊率高(55.3%),钝或无残端(79.2%),中度或重度钙化(50.0%),J-CTO评分高(2.96±0.93)。逆行是44.0%病变的第一个交叉策略,80%的病变成功。与标准血管造影相比,操作者认为人工智能增强的螺旋状弯曲(10.2%对20.6%,p=0.035)和间隔侧支扭曲(31.7%对51.5%,p=0.004)的频率较低,CC2侧支大小的频率较高(6.5%对0.0%,p=0.007)。人工智能增强血管造影的总体预测交叉可能性(85% vs 70%, p<0.001, Wilcoxon检验:p<;0.001)和易解释性(9.00 vs 7.00, p<0.001)更高。两组对杂交成功的预测性能无差异(AUCAI-enhanced = 0.74, AUCstandard = 0.73, De Long检验:p=0.856)。人工智能增强血管造影的成功率中位数高出10.7%。与标准血管造影相比,人工智能增强血管造影可以更容易地解释血管造影,并且在侧枝交叉方面具有相似的预测性能,尽管侧枝复杂性较低。

Hydroxychloroquine (HCQ) cardiotoxicity is increasingly recognized, yet progressive conduction system disease remains underappreciated and may represent a lethal phenotype. We report a 67-year-old female on chronic HCQ who developed progressive conduction abnormalities culminating in cardiogenic shock and sudden death despite initial stabilization with isolated atrial pacing. Autopsy revealed extensive sinoatrial and atrioventricular nodal lysosomal toxicity and fibrosis confirming irreversible conduction injury. This case highlights the lysosomal basis of HCQ toxicity and reframes conduction disease as a primary, irreversible manifestation. Vigilant ECG surveillance and early consideration of dual-chamber pacing may prevent catastrophic outcomes in patients on chronic HCQ therapy.

The clinical impact of transcatheter aortic valve replacement (TAVR) in patients with moderate mixed aortic valve disease (MMAVD)—characterized by the coexistence of moderate aortic stenosis (AS) and aortic regurgitation (AR)—remains unclear, as current evidence primarily focuses on isolated severe AS. This study aimed to compare outcomes of TAVR between patients with MMAVD and those with isolated severe AS. Between January 2019 and June 2024, 848 patients who underwent TAVR at our center were identified for analysis, including 75 with MMAVD and 773 with isolated severe AS. To minimize confounding, 73 MMAVD patients were matched with 264 isolated AS patients using 1:4 propensity score matching for comparative analysis. The primary endpoint was all-cause mortality; secondary endpoints included heart failure rehospitalization, left ventricular (LV) reverse remodeling, and procedural complications. Continuous variables were compared using independent samples t-tests, categorical variables using chi-square or Fisher’s exact tests, and survival using Kaplan–Meier curves with log-rank tests. At baseline, MMAVD patients exhibited greater LV dilation (LV end-diastolic diameter [LVEDD]: 56.07±9.04 vs 50.68±7.70, p < 0.001) and hypertrophy (LV mass index [LVMI]: 163.68±50.17 vs 151.59±44.38, p = 0.026). Post-TAVR, MMAVD showed superior reverse remodeling (ΔLVEDD: −7.18±9.75 vs −2.52±7.64, p < 0.001), though LVEF recovery was comparable (ΔLVEF: 5.47±13.98 vs 6.88±15.20, p = 0.52). Survival rates were similar (log-rank p = 0.370), but MMAVD had higher 1-year heart failure rehospitalization (5.97% vs 0.96%, p = 0.032). In conclusion, TAVR with self-expandable valves yields comparable survival in MMAVD and isolated AS, with more pronounced reverse remodeling in MMAVD despite advanced baseline disease.

Acute coronary syndrome (ACS) significantly impacts global morbidity and mortality, traditionally emphasizing left ventricular (LV) dysfunction. However, the prognostic importance of right ventricular (RV) dysfunction remains underexplored. Cardiac magnetic resonance (CMR), the gold standard for RV assessment, enables precise evaluation of ventricular function and structure. We conducted a retrospective cohort study of 268 patients with ACS who underwent CMR between January 2020 and December 2022 at the National Institute of Cardiology Ignacio Chavez. RV dysfunction was defined as RV ejection fraction (RVEF) <50% by CMR. Multivariate logistic regression identified factors associated with RV dysfunction. RV dysfunction occurred in 170 patients (63.4%). Compared to those without RV dysfunction, patients with RV dysfunction were more likely to be male (84% vs 70%, p = 0.011) and smokers (66% vs 51%, p = 0.017). These patients exhibited reduced LV ejection fraction (39% vs 44%, p < 0.001), higher end-systolic and end-diastolic volumes, and reduced RV fractional area change (42% vs 45%, p = 0.004). BMI (OR 1.13, 95% CI 1.04-1.24, p = 0.008) and mitral regurgitation (OR 5.40, 95% CI 1.47–27, p = 0.020) were independently associated with RV dysfunction. Although mortality was higher among patients with RV dysfunction (3.5% vs 1%), it was not statistically significant (p = 0.4). In conclusion RV dysfunction is common in ACS and it is independently associated with increased BMI and mitral regurgitation. CMR evaluation of RV function in ACS patients may be considered to enhance clinical outcomes. Future research should explore targeted therapeutic interventions for RV dysfunction.

Peripartum cardiomyopathy (PPCM) is a rare but life-threatening condition that occurs in late pregnancy or early postpartum and leads to heart failure with reduced left ventricular ejection fraction (LVEF). A severe complication of PPCM is cardiogenic shock, and its incidence has increased in the recent years. We conducted a retrospective multicenter cohort analysis to evaluate the 180-day clinical outcomes of PPCM complicated by cardiogenic shock (PPCM-CS), with a focus on the role of mechanical circulatory support. We identified 733 patients diagnosed with PPCM-CS between January 2010 and January 2024 using TriNetX, a multi-institutional U.S. health record database. Subgroup analysis evaluated outcomes among patients with no mechanical circulatory support (MCS), those managed with intra-aortic balloon pump (IABP) or percutaneous left ventricular assist device (pLVAD), and those supported with extracorporeal membrane oxygenation (ECMO). At 180-day follow-up, all-cause mortality of overall cohort was 15.8%, with higher mortality observed in ECMO (24.1%) and IABP/pLVAD (18.7%) groups. Durable LVAD implantation occurred in 15.0% of the overall cohort, with higher prevalence in ECMO (17.7%) and IABP/pLVAD (29.0%) groups. Heart transplantation was performed in 12.9% of the overall cohort, with higher prevalence in ECMO (19.0%) and IABP/pLVAD (27.1%) patients. Data on outcomes in patients with PPCM complicated by cardiogenic shock remain limited. This study offers insight into the 180-day outcomes in this high-risk population and suggests that, although MCS is associated with higher mortality, it may serve as a viable bridge to advanced therapies.

Echocardiographic evaluation of Aortic valve stenosis (AS) severity relies on aortic valve area and peak jet velocity. In pursuit of improving accuracy, the transaortic flow rate (FR), defined as the ratio of stroke volume to systolic ejection time, has been introduced. However, its prognostic value in AS patients remains a matter of controversy. This study aims to systematically review the predictive value of FR in AS patients and provide quantitative pooled analysis results where applicable. A systematic search was conducted for observational studies on AS patients published up to July 31, 2025. Studies were included if they assessed the clinical prognostic utility of FR with at least 3 months of follow-up. Pooled estimates and 95% CI for FR's hazard ratio (HR) in each binary outcome were calculated using a random effects model. Twenty-one studies with 10,895 patients underwent descriptive analysis, and 19 eligible studies were included in the meta-analysis. For predicting all-cause mortality, the pooled HR for low FR measured at rest (cut-off value 200–210 mL/s) was 1.31 (95% CI: 1.03–1.60, I2: 66%, p < 0.05). For FR measured during stress echocardiography (cut-off value 250 mL/s), the pooled HR was higher at 1.58 (95% CI: 1.20–1.96, I2: 0%, p < 0.05). However, data in stress echocardiography have been drawn from a smaller number of studies compared to rest FR assessment, and validation in larger studies is warranted. Additionally, every 100 mL/s increase in FR, either at rest or stress, significantly reduced all-cause mortality. In Conclusion, FR is a prognostic marker for all-cause mortality and adverse composite outcomes in AS patients, indicating its potential for risk stratification. Incorporating FR into clinical assessments could help personalize follow-up and monitoring strategies.

Randomized controlled trials investigating colchicine for secondary prevention of cardiovascular events following acute myocardial infarction (AMI) have yielded conflicting results, and the real-world use and effectiveness of colchicine in this context remains unknown. As such, we sought to evaluate the use of colchicine following AMI in clinical practice and the associated outcomes. We performed a retrospective analysis of patients diagnosed with AMI and longitudinally followed in a large academic health system between 2018 and 2024 to describe the clinical use of colchicine for secondary prevention following AMI, as well as patient-level demographic and clinical characteristics associated with colchicine use. Next, using both multivariable logistic regression models with and without propensity matching, we examined the association between colchicine prescription following AMI and composite cardiovascular outcomes (comprised of recurrent AMI, any revascularization, stroke, and death). Kaplan-Meier Event-free Survival Analysis and Cox Proportional Hazards Models were performed. Of 1,796, 126 (7.0%) were prescribed colchicine after AMI. There was no association between use of colchicine and the composite cardiovascular events in either standard multivariable adjusted (Odds Ratio 1.00, 95% CI 0.66–1.50, p = 0.99) or propensity matched models (0.98, 0.57–1.66, p = 0.93). There was no difference in event-free survival between patients who were prescribed colchicine and those who were not. In summary, we report the first real-world data on the use and effectiveness of colchicine for prevention of cardiovascular events after AMI. Colchicine was infrequently prescribed for this indication and was not associated with lower rates of subsequent cardiovascular events.
调查秋水仙碱对急性心肌梗死(AMI)后心血管事件二级预防的随机对照试验得出了相互矛盾的结果,秋水仙碱在这种情况下的实际使用和有效性仍然未知。因此,我们试图评估急性心肌梗死后秋水仙碱在临床实践中的应用及其相关结果。我们对2018-2024年间诊断为AMI的患者进行了回顾性分析,并在一个大型学术卫生系统中进行了纵向随访,以描述秋水仙碱在AMI后二级预防的临床使用情况,以及与秋水仙碱使用相关的患者水平的人口统计学和临床特征。接下来,使用有倾向匹配和没有倾向匹配的多变量logistic回归模型,我们检查了AMI后秋水仙碱处方与复合心血管结局(包括复发性AMI、任何血运重建、中风和死亡)之间的关系。Kaplan-Meier无事件生存分析和Cox比例风险模型。1796例患者中,126例(7.0%)AMI后服用秋水仙碱。在标准多变量调整模型(优势比1.00,95% CI 0.66-1.50, P=0.99)或倾向匹配模型(0.98,0.57-1.66,P=0.93)中,秋水仙碱的使用与复合心血管事件均无关联。服用秋水仙碱的患者和未服用秋水仙碱的患者在无事件生存率方面没有差异。总之,我们报告了秋水仙碱用于预防AMI后心血管事件的使用和有效性的第一个真实数据。秋水仙碱很少用于这一适应症,并且与较低的后续心血管事件发生率无关。

Transcatheter aortic valve replacement (TAVR) is an established treatment for patients with severe symptomatic aortic stenosis (AS). Comparative data on the efficacy and safety of newer transcatheter heart valve (THV) devices is still evolving. We aim to compare clinical and hemodynamic outcomes of the Symetis ACURATE Neo-2® versus the Medtronic Evolut Pro/Pro+® and the Edwards Sapien-3® THVs, from a large cohort of patients undergoing TAVR. In this all-comer, single center trial, patients with severe symptomatic AS undergoing TAVR and treated with either ACURATE Neo-2 (N = 240), Evolut Pro/Pro+ (N = 324) or Sapien-3 (N = 485) THVs were included. Baseline clinical, demographic and follow-up data were collected. Patients (N = 1049) (female 48.6%) mean age 80.1 ± 7.7 years. ACURATE Neo-2 patients were predominantly female (81%) in comparison to Evolut Pro/Pro+ (59%) and Sapien-3 (26%). Need for post-TAVR permanent pacemaker implantation (PPI) was lower in the ACURATE Neo-2 group in comparison to the Evolut Pro/Pro+ and similar to the Sapien-3 group. Rates of ≥ moderate paravalvular leak (PVL) were similar between ACURATE Neo-2 and Evolut Pro/Pro+, but higher in comparison to Sapien-3. In sight of our center's clinical approach to choosing various THV’s according to patient characteristics, The ACURATE Neo-2 constitutes a reliable and suitable tool for the treatment of patients with severe symptomatic AS undergoing TAVR. Even in the wake of the ACURATE Neo-2′s withdrawal, our study offers valuable contributions to ongoing discourse in the field of TAVR, emphasizing the necessity for continuous research and innovation to improve patient care and device efficacy.
