RESUMEN
BACKGROUND: This prospective multicenter study assessed the prevalence of myocardial injury in patients with COVID-19 using cardiac magnetic resonance imaging (CMR). METHODS AND RESULTS: We prospectively screened 505 patients with moderate to severe COVID-19 disease from 7 hospitals in Japan. Of these patients, 31 (mean [±SD] age 63.5±10.4 years, 23 [74%] male) suspected of myocardial injury, based on elevated serum troponin or B-type natriuretic peptide concentrations either upon admission or 3 months after discharge, underwent CMR 3 months after discharge. The primary endpoint was the presence of myocardial injury, defined by any of the following: (1) contrast enhancement in the left or right ventricle myocardium on late gadolinium enhancement CMR; (2) left or right ventricular dysfunction (defined as <50% and <45%, respectively); and (3) pericardial thickening on contrast enhancement. The mean (±SD) duration between diagnosis and CMR was 117±16 days. The primary endpoint was observed in 13 of 31 individuals (42%), with 8 (26%) satisfying the modified Lake Louise Criteria for the diagnosis of acute myocarditis. CONCLUSIONS: This study revealed a high incidence of myocardial injury identified by CMR in patients with moderate to severe COVID-19 and abnormal findings for cardiac biomarkers.

INTRODUCTION: Cardiac resynchronization therapy (CRT) is well-established for treating symptomatic heart failure with electrical dyssynchrony. The left ventricular (LV) lead position is recommended at LV posterolateral to lateral sites in patients with left bundle branch block; however, its preferred region remains unclear in patients being upgraded from right ventricular (RV) apical pacing to CRT. This study aimed to identify the preferred LV lead position for upgrading conventional RV apical pacing to CRT. METHODS: We used electrode catheters positioned at the RV apex and LV anterolateral and posterolateral sites via the coronary sinus (CS) branches to measure the ratio of activation time to QRS duration from the RV apex to the LV anterolateral and posterolateral sites during RV apical pacing. Simultaneous biventricular pacing was performed at the RV apex and each LV site, and the differences in QRS duration and LV dP/dtmax from those of RV apical pacing were measured. RESULTS: Thirty-seven patients with anterolateral and posterolateral LV CS branches were included. During RV apical pacing, the average ratio of activation time to QRS duration was higher at the LV anterolateral site than at the LV posterolateral site (0.90 ± 0.06 vs. 0.71 ± 0.11, p < .001). The decreasing ratio of QRS duration and the increasing ratio of LV dP/dtmax were higher at the LV anterolateral site than at the posterolateral site (45.7 ± 18.0% vs. 32.0 ± 17.6%, p < .001; 12.7 ± 2.9% vs. 3.7 ± 8.2%, p < .001, respectively) during biventricular pacing compared with RV apical pacing. CONCLUSION: The LV anterolateral site is the preferred LV lead position in patients being upgraded from conventional RV apical pacing to CRT.

INTRODUCTION: The presence of an epicardial connection (EC) decreases the success rate of pulmonary vein isolation (PVI); however, the effect of designing isolation lines has not been evaluated. We sought to clarify the effects of designing an anterior line for right-sided PVI considering the presence and location of the EC. METHODS: Seventy-four consecutive patients who underwent initial catheter ablation for atrial fibrillation were retrospectively included in this study. The presence of the EC was determined by the left atrial (LA) activation map during right atrial pacing, and patients were divided into EC-positive (n = 23, 31%) and EC-negative (n = 51, 69%) groups. EC-positive patients were further subdivided based on the EC location: on-the-line group, (EC on the PVI line, n = 11); inside-line group (EC on the pulmonary vein [PV] side, n = 10); and outside-line group (EC on the LA side, n = 2). The PVI parameters were compared among the three groups. RESULTS: The success rates of the first-pass isolation were comparable between the EC-negative and EC-positive groups (70.6% vs. 60.9%, ns), but the success rate was significantly higher in the on-the-line group than in the inside-line group (91% vs. 20%, p = 0.002). First-pass isolation was successful in both patients in the outside-line group. Additional carina ablation was required only in the inside-line group. CONCLUSIONS: The association between the EC site and the right-sided PV anterior isolation line affected the success rate of first-pass isolation. For successful right-sided PVI, it is important to consider the EC site when designing the PVI line.

BACKGROUND: Outcomes of cryoballoon ablation for persistent atrial fibrillation (AF) are unclear, especially in Japanese patients, so the effectiveness and safety of cryoballoon ablation in clinical practice were retrospectively compared with those of contact force-sensing radiofrequency (CFRF) ablation including the high-power protocol.MethodsâandâResults:Consecutive patients with persistent AF were reviewed, and 253 and 265 patients who underwent cryoballoon and CFRF ablation, respectively, were enrolled. The primary endpoint was atrial arrhythmia recurrence. The secondary endpoints were periprocedural complications and repeat ablation. The rate of additional left atrial (LA) ablation after pulmonary vein isolation (PVI) was similar between groups (68.8% cryoballoon vs. 74.0% CFRF, P=0.19). Freedom from atrial arrhythmia recurrence was comparable between groups over a follow-up of 25.5±12.5 months (72.3% cryoballoon vs. 69.8% CFRF; adjusted hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.59-1.21, P=0.36). Outcomes were similar in the subgroups of PVI alone and PVI plus additional LA ablation. LA posterior wall isolation, absence of defragmentation, and low creatine clearance, but not catheter selection, were associated with the primary endpoint. Periprocedural complications (adjusted HR 0.73, 95% CI 0.34-1.54, P=0.41) and repeat ablation (adjusted HR 1.11, 95% CI 0.71-1.74, P=0.64) were similar for both procedures. CONCLUSIONS: Cryoballoon ablation for persistent AF in Japanese clinical practice had acceptable outcomes comparable to those of advanced CFRF ablation.

BACKGROUND: Delirium is associated with high mortality after cardiac surgery. However, evidence on the epidemiology of delirium in patients with acute decompensated heart failure (ADHF) is limited. This study aimed to assess the incidence and prognostic impact of delirium in patients with ADHF. METHODS: This single-center prospective observational study enrolled 132 consecutive patients with ADHF. We utilized the Diagnostic and Statistical Manual of Mental Disorders, fifth edition and classified the patients into two groups according to the presence or absence of delirium. The primary endpoint was 90-day all-cause mortality. The prognostic impact and risk factors of delirium were evaluated using multivariable Cox and logistic regression analyses, respectively. RESULTS: The median patient age was 83 (interquartile range, 75-87) years. Approximately 51.5% were men. Delirium occurred in 36 (27.3%) patients, and hyperactive delirium was the most frequent type (86.1%). The 90-day all-cause mortality was higher in the patients with delirium than in those without (21.6% versus 3.9%, log-rank p = 0.002). Delirium was associated with higher mortality with an adjusted hazard ratio of 6.8 (95% confidence interval, 1.1-42.6, p = 0.042). The risk factors associated with delirium included advanced age, male sex, higher clinical frailty scale score, and dementia. CONCLUSIONS: Delirium was associated with a higher 90-day all-cause mortality in the older adult patients with ADHF. Hyperactive delirium was the most common subtype.

Hypertrophic cardiomyopathy with left ventricular (LV) mid-cavity obstruction and LV apical aneurysm is associated with high morbidity and mortality rates. However, consensus is lacking on the treatment modality for LV mid-cavity obstruction and LV apical aneurysm. Here, we report a case of reduced LV mid-cavity pressure gradient and symptoms, treated using permanent pacing. The effect of permanent pacing on pressure gradient and symptoms lasted for 4 years. As pacing is relatively non-invasive compared to surgical therapy, permanent pacing is a good option, especially in the elderly patients with LV mid-cavity obstruction and apical aneurysm.

A 55-year-old man was presented to the emergency room because of abdominal pain for 4 days. He had a history of atopic dermatitis. Left ventricular (LV) asynergy and thrombus was detected on echocardiography, and superior mesenteric vein thrombosis was detected by computed tomography. There are no reported cases of this combination of thrombi. We hypothesized that the reason for this complication is the combination of coagulation disorder due to atopic dermatitis, silent myocardial infarction, and exacerbation of the coagulation abnormality due to bacteremia, leading to superior mesenteric vein and LV thrombosis. Atopic dermatitis that has potential risk factors of thrombus with sepsis could provoke thrombophilic state. Atopic dermatitis is a common disease, but continuous medical care is essential.

Background: Infective endocarditis rarely results in mitral stenosis. This report presents a case of prosthetic valve infective endocarditis caused by Cutibacterium acnes infection, which resulted in mitral stenosis and was difficult to diagnose. Case summary: A 78-year-old Japanese man underwent aortic and mitral bioprosthetic valve replacement six years prior to the initiation of hormone therapy for prostate cancer. Three weeks after hormone therapy initiation, the patient developed exertional dyspnoea that progressively worsened and ultimately led to orthopnoea. Chest radiography revealed pulmonary congestion, and transthoracic echocardiography revealed mitral stenosis that was not present three months previously. The patient progressed to heart failure, and bicuspid valve replacement was performed. The excised aortic and mitral bioprosthetic valves were covered with vegetations, and pathological examination confirmed the presence of C. acnes. Therefore, the cause of mitral stenosis was infective endocarditis. Discussion: In patient with rapidly progressive prosthetic valve stenosis after valve replacement, infective endocarditis due to C. acnes should be suspected even if blood cultures are negative.
RESUMEN
A 47-year-old man had localized pulmonary edema (LPE) and a massive pulmonary embolism. The cause of LPE was believed to be a high blood supply to the spared pulmonary artery territories without a thrombus. The patient was successfully treated with unfractionated heparin and thrombolytic agents.
RESUMEN
Cardiac masses pose significant diagnostic and therapeutic challenges in clinical practice. A 73-year-old male with a history of atrial fibrillation and percutaneous atrial septal defect (ASD) closure presented with an asymptomatic right atrial mass detected during routine transthoracic echocardiography follow-up. The mass measured 17 mm, with highly echoic peripheral areas and a heterogenous, low-echoic interior. The patient was asymptomatic and had no fever, embolic, or neurological symptoms. Multimodal imaging, including contrast-enhanced computed tomography, magnetic resonance imaging, and transesophageal echocardiography, revealed a mobile nodular mass in the right atrium (RA); however, the results of each modality were not consistently suggestive of a specific disease. The presumptive diagnosis of thrombus was made based on the change and variability of echocardiographic findings over time and the response to antithrombotic medications. Anticoagulant therapy with edoxaban led to the complete resolution of the mass, confirming the diagnosis of a thrombus. This case highlights the importance of multimodal imaging and temporal changes in findings in the diagnosis and management of RA masses and underscores the need for careful thrombotic risk assessment in patients with a history of atrial fibrillation, ASD, and cardiac procedures.
RESUMEN
BACKGROUND: The Heart Failure Association Pretest assessment, echocardiography and natriuretic peptide, functional testing and final aetiology (HFA-PEFF) score has been developed for diagnosing heart failure with preserved ejection fraction (HFpEF), which is frequently associated with atrial fibrillation (AF). We aimed to investigate whether preprocedural HFA-PEFF score could be used to predict clinical outcomes in patients with AF who underwent catheter ablation (CA). METHODS: Overall, 1679 patients with AF who underwent primary CA (71±10 years, 1218 males (72.5%), median follow-up duration 3.3 years) from July 2011 to December 2019 were included in this retrospective study. HFpEF was defined as an HFA-PEFF score ≥5. The primary study outcome was 5-year major adverse cardiovascular and cerebrovascular events (MACCE), which is a composite of all-cause death, hospitalisation for heart failure (HF) and hospitalisation for stroke. RESULTS: The prevalence of HFpEF was 32.3%, but only 7.7% were diagnosed with HF at the time of CHADS2 scoring. Five-year MACCE occurred in 77 patients (4.6%). The cumulative 5-year incidence of MACCE was significantly higher in the HFpEF group than in the non-HFpEF group (11.2% vs 4.8% at 5 years, p<0.001). In the multivariable analysis, HFpEF by the HFA-PEFF score was associated with MACCE (adjusted HR 1.65, 95% CI 1.02 to 2.65, p=0.041). CONCLUSIONS: Early detection of HFpEF using the HFA-PEFF score may have clinical applications in guiding therapeutic decision-making and improving prognosis by preventing HF and stroke in patients with AF undergoing CA.

OBJECTIVE: There is a need for a robust tool to stratify the patient's risk with COVID-19. We assessed the prognostic values of cardiac biomarkers for COVID-19 patients. METHODS: This is a single-centre retrospective cohort study. Consecutive laboratory-confirmed COVID-19 patients admitted to the Kobe City Medical Center General Hospital from July 2020 to September 2021 were included. We obtained cardiac biomarker values from electronic health records and institutional blood banks. We stratified patients with cardiac biomarkers as high-sensitive troponin I (hsTnI), N-terminal pro-B-type natriuretic peptide (NT-proBNP), creatine kinase (CK) and CK myocardial band (CK-MB), using the clinically relevant thresholds. Prespecified primary outcome measure was all-cause death. RESULTS: A total of 917 patients were included. hsTnI, NT-proBNP, CK and CK-MB were associated with the significantly higher cumulative 30-day incidence of all-cause death (hsTnI: <5.0 ng/L group; 4.3%, 5.0 ng/L-99%ile upper reference limit (URL) group; 8.8% and ≥99% ile URL group; 25.2%, p<0.001. NT-proBNP: <125 pg/mL group; 5.3%, 125-900 pg/mL group; 10.5% and ≥900 pg/mL group; 31.9%, p<0.001. CK: Asunto(s)

RESUMEN
Importance: The characteristics and treatment strategies of atrial functional mitral regurgitation (AFMR) are poorly understood. Objective: To investigate the prevalence, clinical characteristics, and outcomes of mitral valve (MV) surgery in AFMR. Design, Setting, and Participants: This retrospective cohort study, called the Real-World Observational Study for Investigating the Prevalence and Therapeutic Options for Atrial Functional Mitral Regurgitation (REVEAL-AFMR), was conducted across 26 Japanese centers (17 university hospitals, 1 national center, 3 public hospitals, and 5 private hospitals). All transthoracic echocardiography procedures performed from January 1 to December 31, 2019, were reviewed to enroll adult patients (aged ≥20 years) with moderate or severe AFMR, defined by preserved left ventricular function, a dilated left atrium, and an absence of degenerative valvular changes. Data were analyzed from May 8, 2023, to May 16, 2024. Exposures: Mitral valve surgery, with or without tricuspid valve intervention. Main Outcomes and Measures: The primary composite outcome included heart failure hospitalization and all-cause mortality. Results: In 177â¯235 patients who underwent echocardiography, 8867 had moderate or severe MR. Within this group, 1007 (11.4%) were diagnosed with AFMR (mean [SD] age, 77.8 [9.5] years; 55.7% female), of whom 807 (80.1%) had atrial fibrillation. Of these patients, 113 underwent MV surgery, with 92 (81.4%) receiving concurrent tricuspid valve surgery. Patients who underwent surgery were younger but had more severe MR (57.5% [n = 65] vs 9.4% [n = 84]; P < .001), a larger mean (SD) left atrial volume index (152.5 [97.8] mL/m2 vs 87.7 [53.1] mL/m2; P < .001), and a higher prevalence of heart failure (according to the New York Heart Association class III [marked limitation of physical activity] or class IV [symptoms of heart failure at rest], 26.5% [n = 30] vs 9.3% [n = 83]; P < .001) than those who remained under medical therapy. During a median follow-up of 1050 days (IQR, 741-1188 days), 286 patients (28.4%) experienced the primary outcome. Despite a more severe disease status, only the surgical group showed a decrease in natriuretic peptide levels at follow-up and had a significantly lower rate of the primary outcome (3-year event rates were 18.3% vs 33.3%; log-rank, P = .03). Statistical adjustments did not alter these findings. Conclusions and Relevance: The findings of this cohort study suggest that in patients with AFMR, who were typically older and predominantly had atrial fibrillation, MV surgery was associated with lower rates of adverse clinical outcomes. Future studies are warranted to investigate a possible causal relationship to better regulate cardiovascular medicine.

Background: Primary cardiac lymphoma (PCL) is a rare cardiac tumour with various presentations, which might cause a complete atrioventricular (AV) block, which can, in turn, cause heart failure symptoms. Case summary: We report a case of a 55-year-old woman with a chief complaint of exertional dyspnoea. Her vital signs showed bradycardia, and electrocardiography revealed a complete AV block. Transthoracic echocardiography revealed a large intra-cardiac mass in the right atrium. Full-body positron emission tomography showed an elevated fluorodeoxyglucose uptake in the right atrial mass, interatrial septum, and wall of the left atrium. Since the tumour could obstruct the tricuspid valve, urgent tumour debulking surgery and epicardial lead implantation were performed. Histopathological examination results were consistent with diffuse large B-cell lymphoma. After several courses of chemotherapy, we kept her in complete remission of the tumour for 2 years. Discussion: Primary cardiac lymphoma was complicated by a complete AV block and diagnosed by using the samples that we obtained in the surgery. A surgical resection of the tumour and epicardial lead implantation, combined with chemotherapy, can be an option, especially in patients who require cardiac surgery.
RESUMEN
Immunoglobulin G4-related disease (IgG4-RD) of the cardiovascular system is rare. Multiple approaches for the management of IgG4-RD have been reported, including surgical resection of affected tissues and treatment with systemic glucocorticoids being generally used. Therefore, the results of surgical resection alone are unknown. A 79-year-old male underwent total aortic arch replacement 5â¯years previously. Subsequently, a coronary aneurysm of the left circumflex artery (LCx) enlarged with pericardial effusion was removed 2â¯years after the first surgery. He was diagnosed with a confirmed IgG4-related coronary aneurysm. Serum IgG4 level was 331â¯mg/dL, and the aneurysm at the distal portion of the LCx was residual. However, he did not receive any corticosteroid treatment. Follow-up transthoracic echocardiography (TTE) revealed an abnormal echo-free cavity structure at 5 o'clock position of the short-axis view. This case describes the progression of residual IgG4-related coronary aneurysm, without corticosteroid therapy. A case with thoracic aortic disease combined with coronary aneurysm may be IgG4-RD. The possibility of progression is high in cases where serum IgG4 remains at a high level, especially without steroid treatment, and follow-up examinations, such as TTE and computed tomography, are more important. Therefore, we reaffirm that corticosteroid therapy may have been important. Learning objective: Immunoglobulin G4-related disease (IgG4-RD) of the cardiovascular system is rare. Multiple approaches for the management of IgG4-RD have been reported, including surgical resection of affected tissues and treatment with systemic glucocorticoids being generally used. Therefore, the results of surgical resection alone, to avoid steroid-related complications, are unknown. Our case showed thoracic aortic disease combined with coronary aneurysm may be IgG4-RD. The importance of corticosteroid treatment was reaffirmed because the residual coronary aneurysm progressed without corticosteroid treatment.
RESUMEN
Background: Primary cardiac lymphoma (PCL) is an extremely rare tumour that typically affects the right heart chamber. It is a life-threatening tumour presenting with rapid growth; therefore, early diagnosis and treatment are crucial for improving the prognosis of patients with PCL. Case summary: An 81-year-old female with a history of dermatomyositis and interstitial pneumonia was referred to the cardiology department for cardiomegaly detected on chest radiography and computed tomography (CT). She experienced shortness of breath on exertion. Electrocardiography revealed negative T-waves in various leads. Transthoracic and transoesophageal echocardiography revealed a large mass on the epicardial free wall of the left atrium and ventricle. Coronary CT angiography showed feeding vessels from the left circumflex artery and the posterolateral branch of the right coronary artery. Positron emission tomography showed elevated mass uptake and no systemic metastasis. Needle biopsy with total endoscopic anterolateral mini-thoracotomy was performed. Histopathological examination revealed diffuse large B-cell lymphoma. She received systemic chemotherapy and achieved a complete metabolic response. Discussion: Herein, we report an extremely rare case of PCL located on the left side of the heart. Owing to the location of the tumour, percutaneous or transcatheter biopsy could not be performed. Early diagnosis with needle biopsy via anterolateral mini-thoracotomy and systemic chemotherapy resulted in good outcomes.
RESUMEN
BACKGROUND: Persistent hypotension (PH) after carotid artery stenting (CAS) is a relatively common complication; however, it is unclear which patients are more likely to experience this phenomenon. Recently, lower left atrial (LA) volume was associated with vasovagal syncope, which has a similar neurological mechanism to hypotension after CAS. This study aimed to investigate whether LA volume can predict PH after CAS. METHODS: This single center retrospective analysis used data from 316 patients who had undergone CAS between March 2013 and February 2021. After the exclusion of urgent CAS, 212 procedures (202 patients) with transthoracic echocardiograms were included. The procedures were divided among two groups according to the presence or absence of PH for more than 1 hour after CAS. RESULTS: The mean age of the patients was 73.0±7.5 years. PH was observed during 52 (24.5%) procedures. The PH group exhibited a lower LA volume index (LAVI) than the no-PH group (29.7±9.1 vs 37.7±12.5 mL/m2, respectively; p<0.001). The area under the receiver operating characteristic curve was 0.716. The optimal cut-off value was 33.5 mL/m2 (sensitivity 0.750, specificity 0.625). Multiple logistic regression analysis showed that LAVI <33.5 mL/m2 was an independent predictor for PH after CAS (OR 4.950, 95% CI 2.190 to 11.200; p<0.001). Preoperative hydration was negatively associated with PH (OR 0.235, 95% CI, 0.070 to 0.794; p=0.020). CONCLUSIONS: A lower LA volume can predict PH after CAS, and preoperative hydration may prevent PH after CAS.

A 69-year-old man with a history of anti-synthetase antibody-positive polymyositis and interstitial lung disease (ILD) stable for more than 20 years suddenly developed pulmonary artery hypertension (PAH) with a mean PA pressure of 46 mmHg. At this stage, ILD was mild, but it became acutely exacerbated later, and high-dose corticosteroid and intravenous cyclophosphamide ameliorated both PAH and ILD. The tricuspid regurgitation pressure gradient decreased from 80 to 49 mmHg and ILD recovered almost completely. During a systemic examination, bone metastatic cancer of unknown origin was found. We herein report the relationship between anti-synthetase syndrome (ASS) and PAH as well as ASS and malignancy.

Background The natural history and optimal interventional timing in patients with isolated severe tricuspid regurgitation (TR) have not been well studied. This study aimed to investigate long-term clinical outcomes and risk factors associated with poor prognosis in patients with isolated severe TR. Methods and Results Consecutive transthoracic echocardiographic examinations in 2877 patients with isolated severe TR were retrospectively reviewed. Patients with significant left-sided valve disease or repeated examinations were excluded. Primary outcome was defined as a composite of all-cause death and hospitalization for heart failure. Among the 613 enrolled patients (mean age, 74±13 years; men, 38%), 141 died, and 62 were hospitalized for heart failure during the median follow-up period of 26.5 (interquartile range, 6.0-57.9) months. The 5-year event-free rate was 60.1%. TR pressure gradient (adjusted hazard ratio [HR], 1.03 [95% CI, 1.01-1.04]), blood urea nitrogen (adjusted HR, 1.02 [95% CI, 1.01-1.04]), left atrial volume index (adjusted HR, 1.01 [95% CI, 1.002-1.02]), and serum albumin (adjusted HR, 0.56 [95% CI, 0.36-0.95]) were identified as independent predictors of adverse events. A risk model based on the 4 clinical factors that included pulmonary hypertension (TR pressure gradient >40 mm Hg), elevated blood urea nitrogen levels (>25 mg/dL), decreased albumin levels (<3.7 g/dL), and left atrial enlargement (left atrial volume index <34 mL/m2) revealed a graded increase in the risk of adverse events (P<0.001). Conclusions The prognosis of isolated severe TR is not always favorable. Careful attention should be paid to patients with concomitant risk factors, such as pulmonary hypertension, elevated blood urea nitrogen levels, decreased albumin levels, and left atrial enlargement.

To our knowledge, there have been no reports of right-sided infective endocarditis (RSIE) with ventricular free wall vegetation caused by Abiotrophia defectiva. We herein report a case of RSIE caused by A. defectiva with ventricular free wall vegetation in a 27-year-old man with ventricular septal defect (VSD). Computed tomography showed multiple bilateral pulmonary nodular shadows. Transesophageal echocardiography (TEE) demonstrated right ventricular free wall vegetation at the jet stream. Blood culture revealed A. defectiva. These findings are consistent with a diagnosis of infective endocarditis and septic pulmonary embolism. Treatment with ceftriaxone and gentamicin and subsequent surgical VSD closure improved the patient's condition without recurrence.
