Abstract

PURPOSE:To compare the inter-center cranial computed tomography (CT) acquisition rates, CT findings, CT related radiation dose, and variability of CT acquisition parameters for neurologic events among patients with implantable cardioverter-defibrillator (ICD) or left ventricular assist device (LVAD).METHODS:A total of 224 patients [ICD group (n = 155) and LVAD group (n = 69)] who had at least one cranial CT scan were enrolled from three medical centers. The variability and effect of the number, indication, and findings of cranial CT scans as well as CT acquisition parameters including tube potential, tube current, tube rotation time (TI), slice collimation (cSL), and spiral or sequential scanning techniques on CT dose index volume (CTDIvol), total dose length product (DLP) were analyzed.RESULTS:The mean DLP value of Center A and mean CTDIvol values of Center A and C were significantly lower than Center B (p < 0.001). The mean CTDIvol and DLP values in the ICD group were substantially lower than the LVAD group (p

Abstract

Aim: Previous data reflected confusions about classification and management of atrial fibrillation (AF) among physicians. Although relatively clear suggestions of dedicated guidelines, poor adaptation of them to routine clinical practice may result with suboptimal prevention and treatment measures. As a main stakeholder of management, physicians' perceptions about the disease have major role. The study aimed to assess confusions and concordances of physicians about the definition and management of the disease. Methods and Results: We developed a web-based survey about AF consisting of 27 questions regarding valvular or non-valvular AF perception, using thromboembolic and bleeding risk scores, antithrombotic management and rate/rhythm control strategies. Two hundred and thirty two physicians participated and 224(97%) of them completed the survey. Although only cardiologists were invited to the survey, 27 physicians from different specialties also responded the survey. Half of the physicians reported that ≥40% of their patients had valvular AF. Dramatically, the survey responses revealed that nearly one-third of physicians classified the AF patients with mitral regurgitation as valvular AF. Most of the physicians denoted that they were using bleeding and stroke risk scores before deciding oral anticoagulation therapy and also preferring long term rhythm-control strategy in AF patients with systolic heart failure. However, results exposed evident disparities among physicians at specific aspects of the disease management. Conclusion: The survey-based study demonstrated a great heterogeneity in classification and management of AF among physicians because of guideline confusions/failures, inadequate evidence about some specific conditions and not being able to dominate the guidelines by physicians.

Abstract

Although pharmacological rhythm control of AF in patients with heart failure with reduced ejection fraction (HFrEF) does not seem to provide any benefit over rate control, catheter ablation of AF has been shown to improve clinical outcomes. These results can be explained with higher success rates of catheter ablation in restoring and maintaining sinus rhythm compared with antiarrhythmic drugs. In addition, pharmacotherapy is not void of side-effects, which are thought to offset its potential antiarrhythmic benefits. Therefore, efforts should be made towards optimisation of ablation techniques for AF in patients with HFrEF.

6. Cryoballoon ablation of focal atrial tachycardia originating from right atrial appendage: Case report and review of the literature

Author

Diseases of the circulatory (Cardiovascular) system, RC666-701
Abstract

The right atrial appendage (RAA) is a rare site of focal atrial tachycardia (AT). Sometimes, catheter ablation cannot successfully be accomplished at this location due to the difficulty in reaching the exact ablation site as well as the associated possible life-threatening complications like pericardial tamponade or perforation. Although radiofrequency (RF) ablation is preferred for the treatment of RAA tachycardias, alternative tools may be required in rare instances. This report presents a case of RAA tachycardia that was not terminated by RF ablation, instead, has been successfully ablated using cryoballoon. In addition, an overview of the literature and therapeutic options for the AT originating from RAA have also been included.

Abstract

We report a case of a 69-year-old male with non-ischemic cardiomyopathy, having drug- and antitachycardia pacing-refractory ventricular tachycardia resulted in multiple ICD shocks. The sustained and intractable ventricular arrhythmia was mapped and ablated with the aid of the three-dimensional electroanatomic mapping system, initially performed but unsuccessful from the endocardial site then performed successfully from the epicardial site via the coronary sinus.

Abstract

The management of atrial arrhythmia recurrence during repeat catheter ablation procedure is unclear despite persistent pulmonary vein isolation. It should be clarified whether an induced non-PV trigger-based (mechanistic) ablation approach more focusing on low-voltage zones is more effective compared to an empirical ablation of low-voltage zones via linear lesions during repeat ablation procedures. The operators should catch all triggers if possible rather than messing with the substrate.

Abstract

BACKGROUND There were gaps between guidelines and practice when surgery was the only treatment for aortic stenosis (AS). OBJECTIVES This study analyzed the decision to intervene in patients with severe AS in the EORP VHD (EURObservational Research Programme Valvular Heart Disease) II survey. METHODS Among 2,152 patients with severe AS, 1,271 patients with high-gradient AS who were symptomatic fulfilled a Class I recommendation for intervention according to the 2012 European Society of Cardiology guidelines; the primary end point was the decision for intervention. RESULTS A decision not to intervene was taken in 262 patients (20.6%). In multivariate analysis, the decision not to intervene was associated with older age (odds ratio [OR]: 1.34 per 10-year increase; 95% CI: 1.11 to 1.61; P = 0.002), New York Heart Association functional classes I and II versus III (OR: 1.63; 95% CI: 1.16 to 2.30; P = 0.005), higher age adjusted Charlson comorbidity index (OR: 1.09 per 1-point increase; 95% CI: 1.01 to 1.17; P = 0.03), and a lower transaortic mean gradient (OR: 0.81 per 10-mm Hg decrease; 95% CI: 0.71 to 0.92; P < 0.001). During the study period, 346 patients (40.2%, median age 84 years, median EuroSCORE II [European System for Cardiac Operative Risk Evaluation II] 3.1%) underwent transcatheter intervention and 515 (59.8%, median age 69 years, median EuroSCORE II 1.5%) underwent surgery. A decision not to intervene versus intervention was associated with lower 6-month survival (87.4%; 95% CI: 82.0 to 91.3 vs 94.6%; 95% CI: 92.8 to 95.9; P < 0.001). CONCLUSIONS A decision not to intervene was taken in 1 in 5 patients with severe symptomatic AS despite a Class I recommendation for intervention and the decision was particularly associated with older age and combined comorbidities. Transcatheter intervention was extensively used in octogenarians. (J Am Coll Cardiol 2021;78:2131-2143) (c) 2021 by the American College of Cardiology Foundation.

Abstract

Mitral annular calcification (MAC) and atherosclerosis are similar in regard to risk factors and pathogenesis. Increased platelet-to-lymphocyte ratio (PLR) has been shown to be associated with atherosclerotic diseases in previous studies. In this study, we aimed to show the association of PLR levels with the presence of MAC.A total of 1060 patients [n = 704 MAC (+), and n = 356 MAC (-)] who were admitted to our cardiology department were enrolled between January 2014 and December 2014. Demographic, clinical, and laboratory parameters of all participants were recorded. PLR was calculated from the complete blood count.The MAC (+) group comprised of those older in age and having a higher rate of hypertension. The mean PLR value was also significantly higher in the MAC (+) group, as compared to that in the MAC (-) group (129.1 ± 32.2 vs 103.5 ± 23.8, p0.001). There was a statistically significant and positive correlation between the neutrophil-to-lymphocyte ratio (NLR) and PLR (r = 0.644, p0.001). Age, hypertension, mean platelet volume, NLR, and PLR (OR: 1.109, 95% CI: 1.101-1.123, p0.001) were independently associated with the presence of MAC.Our results demonstrated that the PLR was significantly increased in patients with MAC, and that the PLR was independently associated with the presence of MAC.

Abstract

Coronavirus disease-2019 (COVID-19) disease is caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) virus infection and firstly appeared in China and then became a pandemic. The leading cause of mortality is respiratory failure in COVID-19; however, cardiovascular manifestations are frequent and also important causes of death in COVID-19. The incidence of arrhythmia is increased in patients with COVID-19 due to increased systemic inflammatory response, hypoxia, and administered drugs. All kinds of arrhythmias, including bradyarrhythmias, supraventricular and ventricular arrhythmias, may develop during COVID-19 course. QT prolongation plays a central role in COVID-19 related arrhythmias. Therefore, QT duration should be strictly followed. All the clinicians should know the management of arrhythmias that they might face with frequently during the pandemic.

Abstract

Introduction: Cachexia, as a miscellaneous phenomenon in heart failure (HF) with a prevalence of 10-15%, is associated with morbidity and mortality. Inflammation has been postulated as the hallmark factor in cachexia pathogenesis. Epicardial Fat Thickness (EFT) is the source of inflammatory mediators and has a close relationship with various cardiac diseases. Beyond other imaging modalities, echocardiography can be a simple and useful method in the evaluation of this tissue. In this study we objected to determine the relation of EFT and cardiac cachexia in heart failure MATERIALS AND METHODS: Our study consisted of totally 100 patients with heart failure with low ejection fraction (EF RESULTS: In patients with cachectic HF (mean age 56.7±13.3, %44 male). EFT were higher than the control group (mean age 58.4±15.0, % 48 male).As a confounding factor; BMI was not different between groups (21.8±2.7 vs. 22.1±3.1, p=0.12).In correlation analysis of EFT with components of cachexia,EFT was significantly positively correlated with CRP (β=0.357 p DISCUSSION: EFT, as an indicator of cardiac inflammatory status, seems to be an important predictor of cardiac cachexia. This noninvasive, simple measurement may guide us at risk stratification of patients with heart failure.

Abstract

Introduction: Heart failure (HF) is a challenging clinical syndrome with complex pathophysiology. Previous studies demonstrated that coronary flow reserve assessed by PET technique was impaired in HF. Transthoracic echocardiography (TTE) can provide reliable data for myocardial blood flow (MBF) which can be measured from coronary sinus (CS). In relation with MBF, coronary vascular resistance (CVR) can be evaluated. In this study, we aimed to evaluate the association of MBF and CVR with clinical data in HF. Methods: The MBF was measured in 100 patients (80 patients with HF (LVEF Results: There was an incremental trend for MBF with advancing NYHA FCs (β=0.253, p=0.015). MBF was similar among HF patients due to NYHA FCs. However, MBF was higher in NYHA FC 4 group compared to healthy subjects (p=0.029). Also, CVR was lower in HF patients than the control group (11.15±6.54 vs.24.84±7.29, p Conclusion: Our results showed that CVR was reduced with advancing FC in HF patients, despite MBF was similar among different FCs. In addition, CVR was significantly correlated with various prognostic markers in HF patients. Therefore, evaluation of MBF hemodynamics, particularly CVR, with TTE may utilize prognostic assessment of HF patients.

Abstract

Over the past decade, catheter ablation has emerged as an important therapeutic option and reserved for drug refractory symptomatic paroxysmal and persistent atrial fibrillation (AF). Although elderly population constitutes the significant amount of AF patients, literature data is inadequate regarding the use of catheter ablation for elderly AF patients. Since there has been significant improvement in efficacy and safety of the AF ablation in last decade, it has become widespread accross the whole world. As the life expectancy continues to grow in population and outcomes of catheter ablation for AF further improve, higher number of elderly patients are likely to undergo catheter ablation for AF. Therefore, in this paper we reviewed the published literature to date regarding the clinical efficacy and safety of catheter ablation for AF in elderly patients.

Abstract

Total white blood cell (WBC) count has been consistently shown to be an independent risk factor and predictor for future cardiovascular outcomes, regardless of disease status in coronary artery disease (CAD). The purpose of this study is to evaluate the relationship between total WBC count and the presence, severity and extent of coronary atherosclerosis detected in subjects undergoing multislice computed tomographic (MSCT) coronary angiography for suspected CAD.A total of 817 patients were enrolled in this cross-sectional study. Non-significant coronary plaque was defined as lesions causing £ 50% luminal narrowing, and significant coronary plaque was defined as lesions causing 〉 50% luminal narrowing. For each segment, coronary atherosclerotic lesions were categorized as none, calcified, non-calcified and mixed. All images were interpreted immediately after scanning by an experienced radiologist.An association between hypertension, diabetes mellitus, age, gender, hyperlipidemia, smoking, total WBC counts and coronary atherosclerosis was found when patients were grouped into two categories according to the presence of coronary atherosclerosis (p 〈 0.05). Although plaque morphology was not associated with total WBC counts, the extent of coronary atherosclerosis was increased with higher total WBC quartiles (p = 0.006). Patients with critical luminal stenosis had higher levels of total WBC counts when compared to patients with non-critical luminal narrowing (7,982 ± 2,287 vs 7,184 ± 1,944, p 〈 0.05).Our study demonstrated that total WBC counts play an important role in inflammation and are associated with the presence, severity and extent of coronary atherosclerosis detected by MSCT. Further studies are needed to assess the true impact of WBC counts on coronary atherosclerosis, and to promote its use in predicting CAD.

Abstract

Behçet's disease, a multisystemic inflammatory disorder, has been associated with a number of cardiovascular dysfunctions, including ventricular arrhythmias and sudden cardiac death. Heart-rate recovery after exercise can provide both an estimate of impaired parasympathetic tone and a prognosis in regard to all-cause and cardiovascular death. The aim of our study was to evaluate heart-rate recovery in Behçet's disease. From January through July 2008, we examined at our outpatient clinic and prospectively enrolled 30 consecutive patients with Behçet's disease and 50 healthy control participants who were matched for age and sex. Basal electrocardiography, echocardiography, and treadmill exercise testing were performed in all patients and control participants. The heart-rate recovery index was calculated in the usual manner, by subtracting the 1st-minute (Rec1), 2nd-minute (Rec2), and 3rd-minute (Rec3) recovery heart rates from the maximal heart rate after exercise stress testing. Patients with Behçet's disease exhibited significantly lower heart-rate recovery numbers, compared with healthy control participants: Rec1, 24.28 +/- 8.2 vs 34.4 +/- 7.6, P = 0.002; Rec2, 49.28 +/- 11.2 vs 57.5 +/- 7.0, P0.05; and Rec3, 56.2 +/- 12.11 vs 67.4 +/- 8.7, P = 0.014. To our knowledge, this is the 1st study that shows an impaired heart-rate recovery index (indicative of reduced parasympathetic activity) among patients with Behçet's disease. Given the independent prognostic value of the heart-rate recovery index, our results may explain the increased occurrence of arrhythmias and sudden cardiac death in Behçet's patients. Therefore, this index may be clinically useful in the identification of high-risk patients.

Abstract

Objective: Atrial structural remodeling has been suggested to contribute to atrial fibrillation (AF) recurrence following direct-current cardioversion (DCCV). The role of several inflammatory and extracellular matrix turnover markers in AF recurrence following DCCV has been investigated. However, data on the impact of galectin-3, which is known to play a role in various fibrotic conditions, including cardiac fibrosis are lacking. The aim of this study was to demonstrate the predictive role of serum galectin-3 levels in AF recurrence following successful DCCV. Methods: A total of 90 persistent AF patients who were sche-duled for DCCV were prospectively enrolled. Serum samples were assayed to determine pre-DCCV galectin-3 levels using the enzyme-linked immunosorbent assay method. Patients were followed up for 3 months for AF recurrence. Results: Of 90 persistent AF patients (mean age: 55.33+-7.94 years; 53.33% male) who underwent successful DCCV, 28 (31.11%) experienced early AF recurrence within 3 months. Patients with AF recurrence had a greater left atrial volume index (LAVI) (33.35+- 2.45 mL/m2 vs. 29.21+-3.08 mL/m2; p

Abstract

Secondary hypertension accounts for 5% to 10% of all hypertensive cases, and renal artery stenosis is one of the most common causes of secondary hypertension. Although atherosclerotic vascular disease and fibromuscular dysplasia are the leading causes of renal artery stenosis, there are other, rare etiologies, such as vasculitis and trauma. A partial nephrectomy is the standard of care treatment option for early stage renal carcinoma patients. Traumatic renal artery stenosis can occur during this surgical intervention, though it is a very rare adverse event, and only a few case reports have been reported in the literature. This report is the description of successful percutaneous treatment of accelerated hypertension secondary to traumatic renal artery stenosis after a partial nephrectomy.

Abstract

Objective: Cardiac resynchronization therapy (CRT) induces structural and electrical reverse remodeling of the failing heart. However, the association between native QRS narrowing and cardiac fibrosis markers has not been investigated in patients with an implanted CRT device. Methods: A total of 41 symptomatic patients diagnosed with systolic heart failure who underwent CRT implantation were included in this study. Electrocardiogram findings and cardiac fibrosis marker levels [galectin-3, growth-differentiation factor-15 (GDF-15) and procollagen III N-terminal propeptide (P3TD)] were collected before and 12 months after initiation of biventricular pacing. Reverse electrical remodeling was defined as a decrease in 12-month intrinsic QRS (iQRS) duration by ≥20 milliseconds after CRT implantation. Results: The median QRS duration decreased from 155 milliseconds (interquartile range [IQR]: 142–178 milliseconds) before CRT to 142 milliseconds (IQR: 130–161 milliseconds) (p=0.001) after 12 months of CRT. According to the predefined criteria, electrical remodeling was detected in 16 (39.0%) patients. The median galectin-3, GDF-15, and P3TD levels were significantly decreased after CRT implantation in patients with electrical remodeling [27.65 ng/mL (IQR: 24.4–35.2 ng/mL) vs 23.00 ng/mL (IQR: 16.0-36.7 ng/mL), p=0.017; 3104 pg/mL (IQR: 2923–4825 pg/mL) vs 2276 pg/mL (IQR: 1294–3209 pg/mL), p=0.002; 0.43 ng/mL (IQR: 0.23–0.64) vs 0.15 ng/mL (IQR: 0.04–0.29 ng/mL), p=0.034, respectively]. The galectin-3, GDF-15, and P3TD levels were not significantly changed in patients without electrical remodeling [26.80 ng/mL (IQR: 23.9–31.5 ng/mL) vs 28.80 ng/mL (IQR: 23.0–34.8 ng/mL), p=0.211; 4221 pg/mL (IQR: 2709–4995 pg/mL) vs 3035 pg/mL (IQR: 2038–4872 pg/mL), p=0.143; and 0.34 ng/mL (IQR: 0.11–0.68 ng/mL) vs 0.21 ng/mL (IQR: 0.09–0.37 ng/mL), p=0.112, respectively]. Conclusion: The results from the small sample used in this study indicated that electrical reverse remodeling after CRT was associated with a decrease in cardiac fibrosis.

Abstract

Brugada syndrome is an inherited cardiac arrhythmia condition characterized by coved-type ST elevation and J point elevation of at least 2 mm in at least 2 of the right precordial electrocardiogram (ECG) leads (V1–3). An increasing number of noncardiac agents, including psychotropic and anesthetic drugs, have been shown to induce a characteristic Brugada ECG pattern, predisposing the patient to fatal ventricular arrhythmias. However, there are scarce data regarding the clinical significance. In this case series, a typical Brugada pattern was unmasked by lithium, valproic acid, and thiocolchicoside; however, the clinical scenario was different in all 3 cases, ranging from an asymptomatic patient to sudden cardiac arrest.
