TOMONORI Takahashi, Tetsuzo Wakatsuki, Takayuki Ise and Masataka Sata : Spontaneous thrombosis of a giant aneurysm complicated with the coronary-to-pulmonary artery fistula: a case report, European Heart Journal. Case Reports, Vol.8, 2024. (Summary) Background A coronary-to-pulmonary artery fistula (CPAF) with a giant aneurysm is a rare clinical occurrence. The rupture of an aneurysm leads to a fatal outcome, thus prompting the incorporation of prophylactic measures, which have encompassed surgical resections or endovascular embolization procedures. The indications for these treatment strategies are controversial, and little has been elucidated regarding the salient characteristics underpinning the selection of a therapeutic strategy. We report a case of a giant aneurysm associated with CPAFs that was thrombosed before interventional treatment. Case summary A 43-year-old woman, who had previously undergone a right adrenalectomy for primary aldosteronism, was referred for an abnormal heart silhouette on a chest X-ray, which had not been seen three years earlier. Contrast-enhanced computed tomography and coronary angiography (CAG) revealed a giant aneurysm on the anterior aspect of the heart associated with two CPAFs. Because of the risk of rupture of the aneurysm, surgical resection was recommended; however, the patient requested endovascular therapy. On the day of intervention, CAG showed spontaneous occlusion of the feeding vessel to the aneurysm, and the aneurysm showed minimal contrast agent, suggesting spontaneous thrombosis. Because of possible recanalization of the aneurysm, coil embolization was performed, without complications. The patient remained asymptomatic, and the aneurysm was completely embolized at the one-year follow-up. Discussion The case shows that minimally invasive endovascular treatment is feasible instead of surgical resection for giant aneurysms associated with CPAFs, depending on their morphological characteristics. This perspective may offer novel insights into treatment strategies for CPAF.

(Summary) The management of mixed aortic valve disease (MAVD), defined as the concomitant presence of aortic stenosis (AS) and aortic regurgitation, remains a clinical challenging. The present study assessed the impact of transcatheter aortic valve replacement (TAVR) on cardiac geometry and prognosis in patients with MAVD. A retrospective multicenter TAVR registry was conducted, including patients who underwent TAVR for severe symptomatic AS between January 2015 and March 2019. Patients were subdivided into 2 groups according to concomitant presence of moderate or more severe aortic regurgitation as the MAVD group, and with mild or less severe aortic regurgitation as the isolated AS group. The primary outcome was a composite of cardiovascular death and rehospitalization due to cardiovascular causes. A total of 1742 patients (isolated AS, 1522 patients; MAVD, 220 patients) were included (84.0±5.2 years). Although MAVD exhibited significantly larger left ventricular volumes and higher left ventricular mass index at the TAVR procedure than isolated AS (respectively, <0.001), MAVD showed a greater improvement of left ventricular volumes and left ventricular mass index after TAVR (respectively, ≤0.001). During a median follow-up of 747 days, 301 patients achieved the primary event. The prognosis post-TAVR was comparable between the 2 groups (log-rank =0.65). Even after adjustment using propensity score matching to reduce the potential bias between the 2 groups, similar results were obtained for the entire cohort. Despite more advanced cardiac remodeling in MAVD at the time of TAVR compared with isolated AS, a greater improvement of cardiac reverse remodeling was found in MAVD, and the prognosis following TAVR was comparable between the 2 groups.

(Summary) The role of the angiotensin receptor neprilysin inhibitor (ARNI) in cardiac function, particularly its impact on pulmonary circulation, remains underexplored. Recent studies have described abnormal mean pulmonary artery pressure (mPAP)-cardiac output (CO) responses as having the potential to assess the disease state. The aim of this study was to assess the effects of ARNI on pulmonary circulation in heart failure. We measured echocardiographic parameters post 6-min walk (6 MW) and compared the changes with baseline and follow-up. Our hypothesis was that pulmonary pressure-flow relationship of the pulmonary circulation obtained by 6 MW stress echocardiography would be improved with treatment. We prospectively enrolled 39 heart failure patients and conducted the 6 MW test indoors. Post-6 MW echocardiography measured echocardiographic variables, and CO was derived from electric cardiometry. Individualized ARNI doses were optimized, with follow-up echocardiographic evaluations after 1 year. Left ventricular (LV) volume were significantly reduced (160.7 ± 49.6 ml vs 136.0 ± 54.3 ml, P < 0.001), and LV ejection fraction was significantly improved (37.6 ± 11.3% vs 44.9 ± 11.5%, P < 0.001). Among the 31 patients who underwent 6 MW stress echocardiographic study at baseline and 1 year later, 6 MW distance increased after treatment (380 m vs 430 m, P = 0.003). The ΔmPAP/ΔCO by 6 MW stress decreased with treatment (6.9 mmHg/L/min vs 2.8 mmHg/L/min, P = 0.002). The left atrial volume index was associated with the response group receiving ARNI treatment for pulmonary circulation. Initiation of ARNI was associated with improvement of left ventricular size and LVEF. Additionally, the 6 MW distance increased and the ΔmPAP/ΔCO was improved to within normal range with treatment.

(Summary) The aim of this study was to identify phenotypes with potential prognostic significance in aortic stenosis (AS) patients after transcatheter aortic valve replacement (TAVR) through a clustering approach. This multi-centre retrospective study included 1365 patients with severe AS who underwent TAVR between January 2015 and March 2019. Among demographics, laboratory, and echocardiography parameters, 20 variables were selected through dimension reduction and used for unsupervised clustering. Phenotypes and outcomes were compared between clusters. Patients were randomly divided into a derivation cohort ( = 1092: 80%) and a validation cohort ( = 273: 20%). Three clusters with markedly different features were identified. Cluster 1 was associated predominantly with elderly age, a high aortic valve gradient, and left ventricular (LV) hypertrophy; Cluster 2 consisted of preserved LV ejection fraction, larger aortic valve area, and high blood pressure; and Cluster 3 demonstrated tachycardia and low flow/low gradient AS. Adverse outcomes differed significantly among clusters during a median of 2.2 years of follow-up ( < 0.001). After adjustment for clinical and echocardiographic data in a Cox proportional hazards model, Cluster 3 (hazard ratio, 4.18; 95% confidence interval, 1.76-9.94; = 0.001) was associated with increased risk of adverse outcomes. In sequential Cox models, a model based on clinical data and echocardiographic variables ( = 18.4) was improved by Cluster 3 ( = 31.5; = 0.001) in the validation cohort. Unsupervised cluster analysis of patients after TAVR revealed three different groups for assessment of prognosis. This provides a new perspective in the categorization of patients after TAVR that considers comorbidities and extravalvular cardiac dysfunction.

(Summary) The Forrester classification plays a crucial role in comprehending the underlying pathophysiology of heart failure (HF) and is employed to categorize the severity and predict the outcomes of patients with acute HF. Our objective was to assess the predictive value of the Forrester classification, based on noninvasive hemodynamic measurements obtained through Doppler echocardiography at admission, in forecasting the short-term prognosis posthospitalization of patients with acute HF. Patients were recruited for the Prospect trial to elucidate the utility of EchocarDIography-based Cardiac ouTput in acute heart failure (PREDICT) study, a multicenter, prospective study conducted in Japan. Participants were stratified into 4 profiles using cardiac index (CI) and early mitral filling velocity (E)/early-diastolic mitral annular velocity (e') ratio obtained from Doppler echocardiography upon admission (profile I: CI >2.2, E/e' ≤15, profile II: CI >2.2, E/e' >15, profile III: CI ≤2.2, E/e' ≤15, profile IV: CI ≤2.2, E/e' >15). The primary composite outcome of the study was all-cause mortality or worsening HF during the 14 days of hospitalization. Cox proportional hazards model analysis was employed to identify prognostic factors during the observation period. A total of 270 subjects, with a mean age of 74 ± 14 years and a male proportion of 60%, were enrolled in the study. During the 14-day period of hospitalization, 58 participants (22%) had a composite outcome. Patients with low CI (i.e., profiles III and IV) demonstrated an elevated risk of composite outcome after adjusting for confounding variables, as evidenced by the adjusted hazard ratios of 5.85 (95% confidence interval 1.17 to 29.09, p <0.01, vs profile III) and 6.50 (95% confidence interval 1.53 to 27.68, p <0.01, vs profile IV) in comparison with profile I, respectively. In conclusion, the Forrester classification, derived from noninvasive Doppler echocardiography at admission, may predict early deterioration in patients hospitalized with acute HF.

(Summary) Vector Flow Mapping (VFM) and Energy Loss (EL) evaluation are emerging echocardiographic techniques that offer detailed insights into cardiac function. This study aimed to explore the relationship between EL parameters and B-type natriuretic peptide (BNP) levels, a well-established marker of heart failure severity. Our study prospectively enrolled 62 patients experiencing shortness of breath and suspected heart failure, who underwent echocardiography and had BNP levels measured between January 2018 and August 2020. Patients were stratified based on BNP levels, and their clinical and echocardiographic characteristics were evaluated. Univariate and multivariate regression analyses were performed to assess the correlation between BNP levels and various echocardiographic variables, including VFM parameters. Patients were stratified into two groups based on their BNP levels: BNP < 200 pg/ml (n = 53) and BNP 200 pg/ml (n = 9). Patients with BNP 200 pg/ml presented significantly different clinical and echocardiographic characteristics, such as older age, larger left ventricular mass and volume indices, higher pulmonary artery systolic pressure, higher E/e' ratio, and larger EL parameters. Multivariate regression analysis demonstrated the E/e' ratio and ELA (EL during Atrial contraction phase/A wave ratio as significant determinants of logBNP. Receiver operating characteristic curve analysis showed ELA/A > 36.0 J/m as a significant predictor of high BNP with 89% sensitivity and 85% specificity. ELA/A demonstrated an incremental diagnostic value over elevated left atrial pressure for predicting high BNP (C statistic = 0.98 vs 0.74, P = 0.006). This study provides novel insights into the potential utility of EL parameters as auxiliary indicators of cardiac load, thereby enhancing our understanding of heart failure.

(Summary) Cancer therapeutics-related cardiac dysfunction (CTRCD) affect the prognosis of patients with breast cancer. Echocardiographic surveillance of patients treated with anti-human epidermal growth factor receptor type 2 (HER2) antibodies has been recommended, but few reports have provided evidence on patients with breast cancer only. We aimed to evaluate the effectiveness of echocardiographic surveillance for breast cancer patients. We identified 250 patients with breast cancer who were treated with anti-HER2 antibodies from July 2007 to September 2021. We divided 48 patients with echocardiographic surveillance every 3 months into the surveillance group and 202 patients without echocardiographic surveillance into the non-surveillance group. In the surveillance group, patients with a considerable reduction in global longitudinal strain of 15 % were considered for the initiation of cardioprotective drugs. The composite outcome of CTRCD and acute heart failure was the study endpoint. The mean age was 59 ± 12 years. During the follow-up period of 15 months (12-17 months), 12 patients reached the endpoint. The surveillance group had significantly lower incidence of the composite outcome (2.1 % vs. 5.5 %, adjusted odds ratio: 0.28, 95 % confidential intervals: 0.09-0.94; p = 0.039) and higher rates of prescriptions of cardioprotective drugs than the non-surveillance group. The incidence of cardiac complications was significantly lower in the surveillance group than the non-surveillance group, which supports the effectiveness of echocardiographic surveillance in patients with breast cancer.

(Summary) In patients with sludge or severe spontaneous echo contrast (SEC) in the left atrial appendage (LAA), cases with isoproterenol loading transesophageal echocardiography (ISP-TEE) have been reported to identify the presence of thrombus in the LAA. This study aimed to assess the validity and hemodynamic changes of ISP-TEE in the LAA. We prospectively enrolled patients with atrial fibrillation (AF) who underwent ISP-TEE. The degree of sludge/SEC was categorized as being either absent (grade 0), mild SEC (grade 1), moderate SEC (grade 2), severe SEC or sludge (grade 3). The hemodynamic evaluation was performed by measuring LAA flow velocity, LAA tissue Doppler imaging (LAA-TDI) velocity, and pulmonary vein systolic forward flow velocity (PVS). In total, 35 patients (mean age 71 ± 7 years; 71% male) underwent ISP-TEE. Among 35 patients, 30 patients had grade 3 or 2 SEC, 5 patients had grade 1 SEC. After ISP loading, 23 patients (66% of all patients) showed improved sludge/SEC and one patient was diagnosed with thrombus in the LAA. There were 25 patients with grade 1 SEC, or no SEC (classified as Group1), 10 patients had residual sludge or grade 2 to 3 SEC (classified as Group2) after ISP administration. LAA flow, LAA-TDI, and PVS velocities were significantly higher in group 1 than in group 2 after ISP administration. There was no complication during the examination and after 24 h and 3 months. ISP infusion may be a potential tool to recognize LAA thrombus under the sludge/SEC during TEE in AF.
