Diagnostic and prognostic value of the left atrial myopathy evaluation in cardiac amyloidosis using echocardiography. ESC Heart Fail 2024. [PMID: 39129371 DOI: 10.1002/ehf2.15013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 06/11/2024] [Accepted: 07/16/2024] [Indexed: 08/13/2024] Open
Abstract
BACKGROUND Cardiac amyloidosis (CA) is an under-recognized cause of heart failure. Left atrial (LA) myopathy contributes to a worse prognosis in heart failure and is a feature of transthyretin (ATTR) and light-chain (AL) CA. LA mechanical dispersion (LA-MD) is a novel marker of intra-atrial dyssynchrony implicated in LA myopathy and the future development of atrial fibrillation (AF). AIMS This study aimed to determine the characteristics and prognostic value of LA myopathy in ATTR and AL cardiomyopathy through a comprehensive LA echocardiographic evaluation. METHODS ATTR (n = 86) and AL (n = 86) CA patients were compared with hypertensive heart disease (HHT) patients (n = 58). Transthoracic echocardiographic measurements including LA strain and LA-MD were obtained with patient follow-up for mortality. RESULTS ATTR and AL patients had a median follow-up of 66 months, with 26 mortality events. Left ventricular (LV) mass, diastolic function (average-e' and E/e'), LV global longitudinal strain, and LA volume and function (LA function index and strain) were more impaired in ATTR versus AL; these echocardiographic parameters were more impaired in both amyloid groups compared to HHT patients (P < 0.05). LA-MD was increased in ATTR versus AL [median 72.2 (inter-quartile range 55-88.9) vs. 54 (43.5-64.2), respectively, P < 0.001]. Multivariable logistic regression adjusted for age, presence of AF, LV mass, global and basal strain, and E/e' demonstrated that LA-MD was an independent determinant of ATTR CA (P = 0.014). On multivariable analysis, LA reservoir strain was independently associated with the presence of heart failure in the CA group (P < 0.001). LA minimum volume (cut-off ≥18 mL/m2) was a determinant of mortality in AL CA [Cox proportional hazard ratio (HR) 1.042 (1.003-1.082), P = 0.034 and Kaplan-Meier analysis, P = 0.016]. CONCLUSION Characterizing LA myopathy has significant diagnostic and prognostic utility in CA. ATTR patients have increased atrial dyssynchrony, which may have implications for AF development. LA reservoir strain was associated with heart failure in CA, whilst LA minimum volume was a predictor of mortality in AL CA.

Potential Role of Left Atrial Strain to Predict Atrial Fibrillation Recurrence after Catheter Ablation Therapy: A Clinical and Systematic Review. J Cardiovasc Dev Dis 2024; 11:203. [PMID: 39057623 PMCID: PMC11277505 DOI: 10.3390/jcdd11070203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 06/20/2024] [Accepted: 06/21/2024] [Indexed: 07/28/2024] Open
Abstract
Pulmonary vein isolation (PVI) with catheter ablation (CA) represents an effective therapy for atrial fibrillation (AF). Unfortunately, it is still not exempt from severe complications. The balance of risks and benefits should be assessed, and a patient-tailored approach is desirable. So far, several clinical and cardiac imaging parameters have been evaluated to investigate pre- and post-procedural features that could help clinicians in the selection of patients at high risk of a poor outcome after CA. This clinical and systematic review analyses the potential role of new LA parameters, such as LA reservoir strain, to predict AF recurrence after CA therapy. Notably, LA reservoir strain gains substantial clinical importance in patients with paroxysmal AF and when a low CHADS2-VASc score is retrieved. LA reservoir strain provides data concerning the risk of AF recurrence after PVI and, thus, in the management of long-term medical therapy in this patient's group.

Abstract
Atrial cardiomyopathy is defined as any complex of structural, architectural, contractile or electrophysiological changes affecting atria, with the potential to produce clinically relevant manifestations. Most of our knowledge about the mechanistic aspects of atrial cardiomyopathy is derived from studies investigating animal models of atrial fibrillation and atrial tissue samples obtained from individuals who have a history of atrial fibrillation. Several noninvasive tools have been reported to characterize atrial cardiomyopathy in patients, which may be relevant for predicting the risk of incident atrial fibrillation and its related outcomes, such as stroke. Here, we provide an overview of the pathophysiological mechanisms involved in atrial cardiomyopathy, and discuss the complex interplay of these mechanisms, including aging, left atrial pressure overload, metabolic disorders and genetic factors. We discuss clinical tools currently available to characterize atrial cardiomyopathy, including electrocardiograms, cardiac imaging and serum biomarkers. Finally, we discuss the clinical impact of atrial cardiomyopathy, and its potential role for predicting atrial fibrillation, stroke, heart failure and dementia. Overall, this review aims to highlight the critical need for a clinically relevant definition of atrial cardiomyopathy to improve treatment strategies.

Impact of Posterior Left Atrial Voltage on Ablation Outcomes in Persistent Atrial Fibrillation: CAPLA Substudy. JACC Clin Electrophysiol 2023; 9:2291-2299.

Abstract
BACKGROUND Pulmonary vein isolation (PVI) is less effective in patients with persistent atrial fibrillation (PsAF). Adjunctive ablation targeting low voltage areas (LVAs) may improve arrhythmia outcomes. OBJECTIVES This study aims to compare the outcomes of adding posterior wall isolation (PWI) to PVI, vs PVI alone in PsAF patients with posterior wall LVAs. METHODS The CAPLA (Effect of Catheter Ablation Using Pulmonary Vein Isolation With vs Without Posterior Left Atrial Wall Isolation on Atrial Arrhythmia Recurrence in Patients With Persistent Atrial Fibrillation) study was a multicenter, randomized trial involving PsAF patients randomized 1:1 to either PVI alone or PVI with PWI. Voltage mapping performed during pacing pre-ablation was reviewed offline, with LVA defined as bipolar voltage of <0.5 mV. The primary endpoint was freedom from any documented atrial arrhythmia of >30 seconds off antiarrhythmic medication at 12 months after a single ablation procedure in patients with posterior LVA. RESULTS A total of 210 patients (average 64.6 ± 9.2 years,73.3% males, median atrial fibrillation duration 4.5 months [IQR: 2 to 8 months]) underwent multipolar left atrial mapping during coronary sinus pacing with posterior LVA present in 69 (32.9%). Patients with posterior LVA were more likely to have LVA in other atrial regions (91.7% vs 57.1%; P < 0.01), larger left atrial diameter (4.8 cm vs 4.4 cm; P < 0.01), and significantly increased risk of atrial arrhythmia recurrence at 12 months (LVA: 56.5% vs no LVA: 41.4%; HR: 1.51; 95% CI: 1.01-2.27; P = 0.04) compared to no posterior LVA. However, the addition of PWI to PVI did not significantly improve freedom from atrial arrhythmia recurrence over PVI alone (PVI with PWI: 44.8% vs PVI: 41.9%; HR: 0.95; 95% CI: 0.51-1.79; P = 0.95). CONCLUSIONS In patients with PsAF undergoing catheter ablation, posterior LVA was associated with a significant increase in atrial arrhythmia recurrence. However, the addition of PWI in those with posterior LVA did not reduce atrial arrhythmia recurrence over PVI alone.

Abstract
BACKGROUND Atrial fibrillation (AF) is the most common pathological arrhythmia, and its complications lead to significant morbidity and mortality. However, patients with AF can often go undetected, especially if they are asymptomatic or have a low burden of paroxysms. Identification of those at high risk of AF development may help refine screening and management strategies. METHODS PubMed and Embase databases were systematically searched for studies looking at electrocardiographic predictors of AF from inception to August 2021. RESULTS A total of 115 studies were reported which examined a combination of atrial and ventricular parameters that could be electrocardiographic predictors of AF. Atrial predictors include conduction parameters, such as the PR interval, p-wave index and dispersion, and partial interatrial or advanced interatrial block, or morphological parameters, such as p-wave axis, amplitude and terminal force. Ventricular predictors include abnormalities in QRS amplitude, morphology or duration, QT interval duration, r-wave progression and ST segment, i.e., t-wave abnormalities. CONCLUSIONS There has been significant interest in electrocardiographic prediction of AF, especially in populations at high risk of atrial AF, such as those with an embolic stroke of undetermined source. This review highlights the breadth of possible predictive parameters, and possible pathological bases for the predictive role of each parameter are proposed.

Abstract
Left atrial cardiomyopathy (LACM) has been an ongoing focus of research for several years. There is evidence that LACM is responsible for atrial fibrillation and embolic strokes of undetermined sources. Therefore, the correct diagnosis of LACM is of clinical importance. Various techniques, including electrocardiography, echocardiography, cardiac magnetic resonance imaging, computed tomography, electroanatomic mapping, genetic testing, and biomarkers, can both identify and quantify structural, mechanical as well as electrical dysfunction in the atria. However, the question arises whether these techniques can reliably diagnose LACM. Because of its heterogeneity, clinical diagnosis is challenging. To date, there are no recommendations for standardized diagnosis of suspected LACM. However, standardization could help to classify LACM more precisely and derive therapeutic directions to improve individual patient management. In addition, uniform diagnostic criteria for LACM could be important for future studies. Combining several parameters and relating them seems beneficial to approach the diagnosis of LACM. This review provides an overview of the current evidence regarding the diagnosis of LACM, in which several potential parameters are discussed and, consequently, a proposal for a diagnostic algorithm is presented.

Abstract
The left and right atria serve as buffer chambers to control the flow of venous blood for ventricular filling. If an atrium is absent, blood does not flow effectively into the ventricle, leading to venous blood retention and low cardiac output. The importance of atrial function has become increasingly recognized, because left atrial (LA) function contributes to cardiac performance, and loss of LA function is associated with heart failure. LA volume change has been used for LA function assessment in experimental and clinical studies. In conjunction with LA pressure, the LA pressure–volume relationship provides a better understanding of LA mechanics. LA strain measurement by speckle tracking echocardiography was introduced to evaluate three components of LA function as a (booster) pump, reservoir and conduit. Furthermore, increasing evidence supports the theory that LA reservoir strain has prognostic utility in various cardiac diseases. In this review, we summarize LA contribution to maintain cardiac performance by evaluating LA function with echocardiography according to our experiences and previous reports. Furthermore, we discuss LA dysfunction in challenging cardiac diseases of cardiac amyloidosis and adult congenital heart disease.

Abstract
BACKGROUND Relevant atrial cardiomyopathy (ACM), defined as a left atrial (LA) low-voltage area ≥ 2 cm2 at 0.5 mV threshold on endocardial contact mapping, is associated with new-onset atrial fibrillation (AF), higher arrhythmia recurrence rates after pulmonary vein isolation (PVI), and an increased risk of stroke. The current study aimed to assess two non-invasive echocardiographic parameters, LA emptying fraction (EF) and LA longitudinal strain (LAS, during reservoir (LASr), conduit (LAScd) and contraction phase (LASct)) for the diagnosis of ACM and prediction of arrhythmia outcome after PVI. METHODS We prospectively enrolled 60 consecutive, ablation-naive patients (age 66 ± 9 years, 80% males) with persistent AF. In 30 patients (derivation cohort), LA-EF and LAS cut-off values for the presence of relevant ACM (high-density endocardial contact mapping in sinus rhythm prior to PVI at 3000 ± 1249 sites) were established in sinus rhythm and tested in a validation cohort (n = 30). Arrhythmia recurrence within 12 months was documented using 72-h Holter electrocardiograms. RESULTS An LA-EF of < 34% predicted ACM with an area under the curve (AUC) of 0.846 (sensitivity 69.2%, specificity 76.5%) similar to a LASr < 23.5% (AUC 0.878, sensitivity 92.3%, specificity 82.4%). In the validation cohort, these cut-offs established the correct diagnosis of ACM in 76% of patients (positive predictive values 87%/93% and negative predictive values 73%/75%, respectively). Arrhythmia recurrence in the entire cohort was significantly more frequent in patients with LA-EF < 34% and LASr < 23.5% (56% vs. 29% and 55% vs. 26%, both p < 0.05). CONCLUSION The echocardiographic parameters LA-EF and LAS allow accurate, non-invasive diagnosis of ACM and prediction of arrhythmia recurrence after PVI.

Kalaycıoğlu E, Çetin M, Kırış T, Özyıldız AG. Paradoxical association between lipoprotein cholesterol levels and left atrial function in hypertensive diabetic patients: A speckle tracking study. JOURNAL OF CLINICAL ULTRASOUND : JCU 2021; 49:667-673. [PMID: 34137047 DOI: 10.1002/jcu.23032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Revised: 06/07/2021] [Accepted: 06/08/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Studies have shown that subclinical left atrial (LA) dysfunction can be diagnosed with two-dimensional speckle tracking echocardiography (2D-STE). Although low-density lipoprotein cholesterol (LDL-C) is a risk factor for cardiovascular diseases, recent studies have reported a paradoxical relationship between LDL-C level and atrial fibrillation. In this study, we investigated the relationship between LDL-C levels and LA function. METHODS In 168 patients with the diagnosis of hypertension and diabetes, transthoracic echocardiography with LA 2D-STE was performed. The patients were then divided into two groups: normal LA-strain (n = 94) or impaired LA-strain (n = 74). The relationship between LDL-C and LA function was analyzed. RESULTS Patients with impaired LA-strain had higher body mass index (BMI) (p = 0.029), higher statin usage (p = 0.003), and lower LDL-C levels (p = 0.001) than patients with normal LA-strain. They also had lower left ventricle ejection fraction (LVEF) (p = 0.047) and higher E-wave velocity (mitral e, m/s) (p = 0.020). Multivariate logistic regression analysis showed that lower LDL-C (p = 0.034), higher BMI (p = 0.004), lower LVEF (p = 0.004), and higher E-wave velocity (p = 0.003) values were independently associated with impaired LA-strain. The area under the receiver operating curve of LDL-C in predicting impaired LA-strain was 0.645 (0.564-0.730, p < 0.05). LDL-C ≤ 112.5 mg/dl was found to be the optimal cut-off value with 74.5% sensitivity and 51.2% specificity in predicting impaired LA strain. CONCLUSION In patients with hypertension and diabetes, LDC-C levels are moderately but independently and paradoxically associated with impaired LA function assessed by 2D-STE.

J Cardiol 2021; 78:517-523. [PMID: 34334266 DOI: 10.1016/j.jjcc.2021.07.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 06/24/2021] [Accepted: 06/26/2021] [Indexed: 01/15/2023]
Abstract
BACKGROUND Left atrial (LA) global strain has been studied as an early marker of LA dysfunction, followed by LA dilatation. Recently, a novel dedicated software for LA 3-dimensional speckle tracking echocardiography (LA-3DSTE) has allowed us to assess anatomy-based six-segmental LA deformation. This study aimed to assess the accuracy of LA-3DSTE software in measuring LA volume and to reveal the characteristics of regional LA reservoir strain. METHODS Fifty patients with paroxysmal atrial fibrillation who underwent computed tomography (CT) and 3D-STE were enrolled. The LA volumes obtained by 3D-STE and CT were compared, and regional LA strain was analyzed. Six LA segments (anterior, septal, inferior, lateral, roof, and posterior) were determined on the basis of LA anatomy. RESULTS In 50 patients (mean age, 64 years; 62% male), the 3D-STE-derived LA volume index (LAVI) showed good correlation with the CT-derived index, (r = 0.78, p < 0.001) with an underestimate bias of 10.5 ± 11.0 ml/m2 (p < 0.001). The lateral LA strain was negatively correlated with LAVI and emptying fraction, while the anterior and septal strains were not. In the 1st quantile LA volume group, the segmental LA strain was heterogeneous, that is, the lateral and inferior strains were greater than the anterior strain. While in the 3rd quantile LA volume group, the lateral and inferior strains were decreased, and there was no regional difference. CONCLUSION LA volume obtained by 3D-STE and CT showed a good correlation. LA segmental analysis by 3D-STE enables early identification of how LA dysfunction affects lateral and inferior LA strains, consistent with anatomical features.

Paroxysmal atrial fibrillation with high vs. low arrhythmia burden: atrial remodelling and ablation outcome. Europace 2021; 22:1189-1196.

Abstract
AIMS The relation between atrial tachyarrhythmia (ATA) burden in paroxysmal atrial fibrillation (AF), atrial remodelling, and efficacy of catheter ablation (CA) is unknown. We investigated whether high vs. low-burden paroxysmal AF patients have distinct clinical characteristics or electro-mechanical properties of the left atrium (LA) and whether burden impacts outcome of CA. METHODS AND RESULTS Atrial tachyarrhythmia burden, defined as the percentage of time spent in ATA, was assessed by insertable cardiac monitors in 105 patients before and after CA. Clinical characteristics and electro-mechanical properties of LA were compared between patients with high vs. low ATA burden. Catheter ablation efficacy was assessed by reduction in ATA burden and 1-year freedom from any ATA. Median ATA burden was 2.7% (highest tertile 9.3%). Clinical characteristics and electrical properties of LA (refractoriness, conduction velocity, low voltage) did not differ between high (≥9.3%) vs. low ATA burden (<9.3%) patients. High ATA burden patients had larger LA diameter (46.5 ± 6 vs. 42.5 ± 6mm, P < 0.01), volume (93.8 ± 22 vs. 80.4 ± 21mL, P = 0.01), and lower LA reservoir and contractile strain (19.7 ± 6 vs. 24.7 ± 6%, P < 0.01; 10.3 ± 3 vs. 12.8 ± 4%, P = 0.01). Catheter ablation reduced ATA burden by 100% (100-100) in both groups (P = 1.0). Freedom from ATA after CA was equally high (83% vs. 89%, P = 0.38). CONCLUSION Paroxysmal AF patients with high ATA burden have altered LA mechanical properties, reflected by larger size and impaired function. Despite mechanical remodelling of the atria, they are excellent responders to CA. Most likely the lack of fibrosis and/or advanced electrical remodelling explain why pulmonary veins remain the dominant trigger for AF in this patient cohort.

Assessment of right atrial dyssynchrony by 2D speckle-tracking in healthy young men following high altitude exposure at 4100 m. PLoS One 2021; 16:e0247107.

Abstract
Background High altitude exposure induces overload of right-sided heart and may further predispose to supraventricular arrhythmia. It has been reported that atrial mechanical dyssynchrony is associated with atrial arrhythmia. Whether high altitude exposure causes higher right atrial (RA) dyssynchrony is still unknown. The aim of study was to investigate the effect of high altitude exposure on right atrial mechanical synchrony. Methods In this study, 98 healthy young men underwent clinical examination and echocardiography at sea level (400 m) and high altitude (4100 m) after an ascent within 7 days. RA dyssynchrony was defined as inhomogeneous timing to peak strain and strain rate using 2D speckle-tracking echocardiography. Results Following high altitude exposure, standard deviation of the time to peak strain (SD-TPS) [36.2 (24.5, 48.6) ms vs. 21.7 (12.9, 32.1) ms, p<0.001] and SD-TPS as percentage of R–R’ interval (4.6 ± 2.1% vs. 2.5 ± 1.8%, p<0.001) significantly increased. Additionally, subjects with higher SD-TPS (%) at high altitude presented decreased right ventricular global longitudinal strain and RA active emptying fraction, but increased RA minimal volume index, which were not observed in lower group. Multivariable analysis showed that mean pulmonary arterial pressure and tricuspid E/A were independently associated with SD-TPS (%) at high altitude. Conclusion Our data for the first time demonstrated that high altitude exposure causes RA dyssynchrony in healthy young men, which may be secondary to increased pulmonary arterial pressure. In addition, subjects with higher RA dyssynchrony presented worse RA contractile function and right ventricular performance.

Abstract
BACKGROUND Strain imaging during left atrial (LA) reservoir phase (LASr) is used as a surrogate for LA structural remodeling and fibrosis. Atrial fibrillation (AF) patients with >5% low-voltage zones (LVZs) obtained by 3D-electro-anatomical-mapping have higher recurrence rate post-ablation. We investigated the relationship between LA remodeling using two-dimensional-speckle-tracking echocardiography (2D-STE) and high-density voltage mapping in AF patients. METHODS A prospective study of 42 consecutive patients undergoing AF ablation. 2D-echo, 2D-STE, and high-density contact LA bipolar voltage maps were constructed before ablation. LVZs were determined with different bipolar amplitudes and their ratio per patient's LA area were investigated for correlation with LASr. We compared 2D-LASr results in patients with LVZs ≥ 5% (LVZs group) versus those with LVZ < 5% (non-LVZs group). RESULTS Compared with non-LVZs group (n = 15), LVZs group (n = 27) included significantly older patients, more women, more persistent AF, higher CHA2 DS2 -VASc score, higher E/A ratio and higher LA volume index (p < .05). LVZs group had lower %LASr values (12.4 ± 5.9% vs. 21.1 ± 6.3, respectively; p<.001). LVZs% in different amplitudes (<0.1 mV, <0.2 mV, and <0.5 mV) were negatively correlated with %LASr (r = -.63, r = -.68, and r = -.72, respectively; p< .001). Atrial strain thresholds for LVZs ≥ 5% in amplitudes <0.1 mV, <0.2 mV, and <0.5 mV were associated with %LASr 12.98, 16.16 and 19.55, respectively; p< .05). In a multivariate analysis, %LASr was the only independent indicator of LVZs (OR, 0.8; 95% CI, 0.6-0.9; p= .04). CONCLUSIONS LVZs ≥ 5% has a negative association with atrial %LASr. Thus, a simple 2D-STE measurement of %LASr can be used as a noninvasive method to evaluate significant LA remodeling and fibrosis in AF patients.

Abstract
Background Atrial fibrillation (AF) during high-dose melphalan and autologous stem-cell transplantation (HDM/SCT) for light-chain (AL) amyloidosis confers significant morbidity. Traditional risk factors provide limited prediction for development of paroxysmal AF during this vulnerable period. Objectives We sought to assess the association of clinical and echocardiographic parameters, including left atrial (LA) mechanics and development of AF in patients undergoing HDM/SCT therapy. Methods Baseline echocardiograms, electrocardiograms, and electronic medical records were retrospectively assessed among patients with AL amyloidosis before HDM/SCT (n = 91). LA function analysis was performed using speckle-tracking echocardiography. Results In this study, 42 patients (46%) had cardiac involvement; in the peri-transplant period, 12 (13%) developed AF (7 with cardiac involvement). No significant differences in age, sex, cardiac biomarkers, or cardiac risk factors were seen between patients with and without development of AF; one-third of patients with AF peri-transplant had previous AF. Although LA reservoir strain was reduced in patients with development of AF, time to peak strain rate indexed to R-R interval (TPSRI) (p = 0.001) was prolonged in patients with development of AF compared with sinus rhythm patients in the total cohort but also in subgroups with and without cardiac involvement. Conclusions TPSRI, a parameter of mechanical dispersion in the early reservoir phase of LA function, is associated with development of AF among patients undergoing HDM/SCT for AL amyloidosis. These findings require validation in larger prospective cohorts.

Abstract
Background: Heart failure may induce atrial dyssynchrony. We aim to investigate whether preimplantation left atrial (LA) dyssynchrony could predict newly detected atrial high-rate episodes (AHRE) after receiving cardiac resynchronization therapy defibrillator (CRT-D). Methods: We conducted a retrospective analysis of consecutive patients who received CRT-D for standard indications and without a history of atrial fibrillation. The standard deviation of the time-to-peak strain in each LA segment during ventricular systole (SDs) and late diastole (SDa) were calculated to quantify LA dyssynchrony using two-dimensional speckle tracking echocardiography before device implantation. Patients were divided into the AHRE group and the AHRE-free group, depending on the presence of AHRE during device interrogation. Results: Thirty-one patients (28%) had newly detected AHRE during a mean follow-up of 21 ± 9 months. Patients in the AHRE group had higher SDs (8.2 ± 2.6% vs. 6.3 ± 2.3%, p < 0.001) and SDa (5.4 ± 1.8% vs. 4.1 ± 1.4%, p < 0.001) values before implantation than patients in the AHRE-free group. In the multivariate logistic analysis, both SDs (OR 1.325, 95% CI: 1.074–1.636, p =0.009) and SDa (OR: 1.499, 95% CI: 1.071–2.098, p= 0.018) were independent predictors of newly detected AHRE. At a cutoff value of 7.4% for SDs and 5.3% for SDa, the Kaplan-Meier survival analysis showed that patients with higher SDs and SDa had significantly increased risks of newly detected AHRE after receiving CRT-D. Conclusions: Dyssynchronous LA lengthening and contraction could assist in the prediction of newly detected AHRE in patients with CRT-D.

Abstract
Low atrial endocardial bipolar voltage, measured during catheter ablation for atrial fibrillation (AF), is a commonly used surrogate marker for the presence of atrial fibrosis. Low voltage shows many useful associations with clinical outcomes, comorbidities and has links to trigger sites for AF. Several contemporary trials have shown promise in targeting low voltage areas as the substrate for AF ablation; however, the results have been mixed. In order to understand these results, a thorough understanding of voltage mapping techniques, the relationship between low voltage and the pathophysiology of AF, as well as the inherent limitations in voltage measurement are needed. Two key questions must be answered in order to optimally apply voltage mapping as the road map for ablation. First, are the inherent limitations of voltage mapping small enough as to be ignored when targeting specific tissue based on voltage? Second, can conventional criteria, using a binary threshold for voltage amplitude, truly define the extent of the atrial fibrotic substrate? Here, we review the latest clinical evidence with regard to voltage-based ablation procedures before analysing the utility and limitations of voltage mapping. Finally, we discuss omnipole mapping and dynamic voltage attenuation as two possible approaches to resolving these issues.

Assessment of left atrial remodeling in paroxysmal atrial fibrillation with speckle tracking echocardiography: a study with an electrophysiological mapping system.

Abstract
This study aimed to evaluate left atrial (LA) remodeling and fibrosis in paroxysmal atrial fibrillation (AF) using speckle tracking echocardiography (STE) based on the findings with radiofrequency catheter ablation (RFCA) so as to predict atrial remodeling prior to ablation. A total of 40 patients with paroxysmal AF were enrolled and divided into two groups based on LA bipolar voltage detected during RFCA: those with low-voltage zone (LVZ) (LV group, n = 19) and those without LVZ (non-LV group, n = 21). The segmental and global LA reservoir, conduit and contractile strain (εs, εe, εa) were analyzed using two-dimensional STE before RFCA. The segmental and global εs, εe, εa (%) decreased in the LV group. Especially, the εs in anteroseptal upper (18.32 ± 7.94 vs. 31.61 ± 9.39) and lower segments (16.60 ± 7.23 vs. 29.23 ± 9.81), posteroseptal upper (22.24 ± 6.65 vs. 32.23 ± 10.57) and lower segments (18.24 ± 6.49 vs. 26.40 ± 7.12), and the global εs (23.85 ± 6.74 vs. 30.48 ± 8.67) significantly decreased in the LV group than in the non-LV group (all P < 0.05). The εs ≤ 24.07 in the anteroseptal upper segment was an effective parameter to differentiate the LV group (sensitivity, 84%; specificity, 81%, P < 0.001). Besides, global εs tended to be an independent determinant of the LVZ (odds ratio 1.347, P = 0.046). STE enables a noninvasive method to evaluate LA remodeling prior ablation.

Abstract
Recently, studies using late gadolinium enhancement (LGE) magnetic resonance imaging (MRI) to identify structural changes of atrial tissue have contributed significantly to understanding the pathophysiology and progression of atrial fibrillation (AF). Moreover, imaging of atrial fibrosis using MRI has evolved to be a tool to improve clinical outcome of AF ablation procedures by allowing a patient-specific individualized management approach. LGE-MRI has been shown to predict AF ablation outcome based on pre-procedural imaging to define the extent of atrial fibrosis. The results of the ongoing DECAAF II (Delayed-Enhancement MRI Determinant of Successful Radiofrequency Catheter Ablation of Atrial Fibrillation) trial might extend ablation strategies from pulmonary vein isolation alone to a substrate-based approach. Furthermore, an improved understanding of the underlying mechanisms of atrial structural remodeling is crucial in order to reduce the occurrence of AF-associated complications (e.g., ischemic stroke and heart failure). This review article provides current methodology of atrial fibrosis imaging using LGE-MRI and delineates actual clinical implications and future directions for this imaging approach.

Abstract
Several cardiac imaging modalities are able to visualize the left atrium (LA) and, therefore, allow for quantification of both structural and functional properties of this cardiac chamber. In echocardiography, only the maximal LA volume is included in the assessment of diastolic function at the current moment. Numerous studies, however, have shown that functional measures may be superior to the maximal LA volume in several aspects and to possess clinical value even in the absence of structural abnormalities. Such functional measures could prove particularly useful in the setting of predicting atrial fibrillation, which will be a point of focus in this review. Pivotal cardiac magnetic resonance imaging studies have revealed high correlation between LA fibrosis and risk of atrial fibrillation recurrence after catheter ablation, and subsequent multimodality imaging studies have uncovered an inverse relationship between LA reservoir function and degree of LA fibrosis. This has sparked an increased interest into the application of advanced imaging modalities, including both speckle tracking echocardiography and tissue tracking by cardiac magnetic resonance imaging. Even though increasing evidence has supported the use of functional measures and proven its superiority to the maximal LA volume, they have still not been adopted in clinical guidelines. The reason for this discrepancy may rely on the fact that there is little to no agreement on how to technically perform deformation analysis of the LA. Such technical considerations, limitations, and alternate imaging prospects will be addressed in this review.

Left atrial strain assessed by three-dimensional speckle tracking echocardiography predicts atrial fibrillation recurrence after catheter ablation in patients with paroxysmal atrial fibrillation. J Echocardiogr 2017; 15:79-87. [PMID: 28155065 DOI: 10.1007/s12574-017-0329-5] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Revised: 12/14/2016] [Accepted: 01/18/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND Several studies have shown the utility of left atrial (LA) function determined by two-dimensional or three-dimensional speckle tracking echocardiography (2D- or 3D-STE) for identifying patients with paroxysmal atrial fibrillation (AF). However, whether 3D-STE is applicable for prediction of the recurrence of AF after catheter ablation (CA) remains unknown. We examined whether any 3D-STE parameters are better than 2D-STE parameters for the prediction of AF recurrence. METHODS Forty-two patients with paroxysmal AF (58 ± 10 years old, 69% male) underwent 2D- and 3D-STE within 3 days before first-time CA. The global peak LA longitudinal, circumferential, and area strains during systole (3D-GLSs, -GCSs, and -GASs, respectively) and those just before atrial contraction (3D-GLSa, -GCSa, and -GASa, respectively) were determined by 3D-STE and standard deviations of times to peaks of regional LA strains were calculated as indices of LA dyssynchrony. In 2D-STE, global LA longitudinal strains during systole and just before atrial contraction (2D-GLSs and -GLSa) were determined. RESULTS During follow-up of 441 ± 221 days, 12 patients (29%) had AF recurrence. In the univariate Cox proportional hazard analysis, age [hazard ratio (HR): 1.08, p = 0.04], 3D-GCSs (HR: 0.91, p = 0.03), and 3D-GASs (HR: 0.95, p = 0.01) were predictors of AF recurrence, though associations of recurrence with 2D-STE parameters, indices of LA synchrony, and LA volume were not significant. Multivariable analysis showed that 3D-GASs was an independent predictor of AF recurrence (HR: 0.96, p = 0.048). CONCLUSIONS LA strain determined by 3D-STE is a novel and better predictor of AF recurrence after CA than that determined by 2D-STE or other known predictors.

Abstract
BACKGROUND The effect of alcohol consumption on substrate remodeling and ablation outcome of paroxysmal atrial fibrillation (PAF) remains unknown. METHODS AND RESULTS We performed circumferential pulmonary vein isolation (CPVI) and voltage mapping of left atrium (LA) during sinus rhythm in 122 consecutive patients with symptomatic PAF (age, 55.4±9.4 years; 73.8% men). Low-voltage zones (LVZs) were semiquantitatively estimated and presented as low-voltage index (LVI). Each patient's daily alcohol consumption history was recorded at baseline and classified into alcohol abstainers, moderate drinkers, and heavy drinkers based on the National Institute on Alcohol Abuse and Alcoholism definition. Follow-up was ≥12 months for AF recurrence. Alcohol abstainers and moderate and heavy drinkers were 70 (57.4%), 13 (10.6%), and 39 (32.0%), respectively. In total, LVZs were observed in 44 patients (36.1%). Daily alcohol consumption independently predicted presence of LVZs (odds ratio [OR], 1.097; 95% confidence interval [CI], 1.001-1.203; P=0.047). During mean follow-up of 20.9±5.9 months, 40 patients (35.1%) experienced AF recurrence. Success rate was 81.3%, 69.2%, and 35.1% in alcohol abstainers, moderate drinkers, and heavy drinkers, respectively (overall log rank, P<0.001). Multivariate analysis showed that both alcohol consumption and LVI were independent predictors of AF recurrence (hazard ratio [HR], 1.579; 95% CI, 1.085-2.298; P=0.017; HR, 2.188; 95% CI, 1.582-3.026; P<0.001, respectively). Furthermore, mediation analysis revealed that LVZs acted as a partial mediator in effect of alcohol consumption on AF ablation outcomes. CONCLUSIONS Daily alcohol consumption was associated with atrial remodelling, and heavy drinkers have substantial risk for AF recurrence after CPVI.

Abstract
BACKGROUND Symptomatic left atrial (LA) flutter (LAFL) is common after atrial fibrillation (AF) ablation. OBJECTIVE The purpose of this study was to examine the association of baseline LA function with incident LAFL after AF ablation. METHODS The source cohort included 216 patients with cardiac magnetic resonance (CMR) before initial AF ablation between 2010 and 2013. Patients who underwent cryoballoon or laser ablation, patients with AF during CMR, and those with suboptimal CMR, or missing follow-up data were excluded. Baseline LA volume and function were assessed by feature-tracking CMR analysis. RESULTS The final cohort included 119 patients (mean age 58.9 ± 11 years; 76.5% men; 70.6% patients with paroxysmal AF). During a median follow-up of 421 days (interquartile range 235-751 days), 22 patients (18.5%) had incident LAFL. Baseline LA volume was similar between the 2 groups. In contrast, baseline reservoir, conduit, and contractile function of the LA were significantly impaired in patients with incident LAFL. Baseline global peak longitudinal atrial strain (PLAS) <22.65% predicted incident LAFL with 86% sensitivity and 68% specificity (C statistic 0.76). In a multivariable model adjusting for age, heart failure, and LA volume, PLAS (hazard ratio 0.9 per % increase in PLAS; P = .003) and LA linear lesions (hazard ratio 2.94; P = .020) were independently associated with incident LAFL. The coexistence of PLAS <22.65% and linear lesions was associated with 9-fold increased hazard of incident LAFL. CONCLUSION Baseline LA function and linear lesions were independently associated with incident LAFL after AF ablation. Linear lesions should be limited to selected cases, especially in patients with impaired LA function.
