RESUMO
BACKGROUND: Chronic kidney disease (CKD) and end-stage renal disease are considered independent risk factors for developing atrial fibrillation (AF). Percutaneous occlusion of left atrial appendage (LAAC) using WATCHMAN device is a widely accepted alternative to anticoagulation therapy to prevent ischemic stroke in AF in patients who are not candidates for anticoagulation. There is limited data regarding the utilization and periprocedural safety of this intervention in patients with CKD/ESRD. METHODS: We retrospectively reviewed all hospitalizations from 2016 to 2017 with (ICD-10) procedure diagnosis code of LAA closure using WATCHMAN procedure with and without a secondary diagnosis of CKD/ESRD in acute-care hospitals across the United States using the national inpatient sample. Demographic variables (gender, race, income, hospital characteristics, medical comorbidities) were collected and compared. The primary outcomes were inpatient mortality, hospital length, and cost of stay. RESULTS: There were over 71 million discharges included in the combined 2016 and 2017 NIS database. Sixteen thousand five hundred five hospitalizations were for adult patients with a procedure code for LAA closure via watchman procedure. Of 16,505 patients, 3245 (19.66%) had CKD and ESRD. There was no statistically significant difference in mortality, length, and cost of stay in patients with and without CKD/ESRD. There were no statistically significant differences in periprocedural cerebrovascular accidents in both groups. CONCLUSION: Patients with and without ESRD/CKD who undergo LAA occlusion with Watchman have similar procedure related, in-hospital mortality, and complications.

Inappropriate sinus tachycardia (IST) has been defined as a resting heart rate of >100 beats per minute and an average 24-hour heart rate >90 bpm with distressing symptoms resulting from the persistent tachycardia. IST is prevalent in 1% of the middle-aged population, mostly females. Rarely can elderly patients also present with IST. Possible mechanisms of IST include intrinsic sinus node abnormality, beta-adrenergic receptor stimulating autoantibody, beta-adrenergic receptor supersensitivity, muscarinic receptor autoantibody, or hyposensitivity, impaired baroreflex control, depressed efferent parasympathetic/vagal function, nociceptive stimulation, central autonomic overactivity, aberrant neurohumoral modulation, etc. Symptoms associated with IST are palpitations, chest pain, fatigue, shortness of breath, presyncope, and syncope. Despite these distressing symptoms, IST has not been associated with tachycardia-associated cardiomyopathy or increased major cardiovascular events. Various treatment options for patients with IST are ivabradine, beta-adrenergic blockers, calcium channel blockers, psychiatric evaluation, and exercise training. Although, endocardial radiofrequency ablation targeting the sinus node has been used as a treatment modality for otherwise treatment-refractory IST, the results have been dismal. The other modalities used for refractory IST treatment are endocardial modification of the sinus node using radiofrequency energy, combined endo and epicardial ablation of the sinus node, thoracoscopic epicardial ablation of the sinus node, sinus node sparing thoracoscopic and endocardial hybrid ablation. The goal of this review is to provide the readership with the pathophysiological basis of IST and its management options.

In the next 20 years, the percentage of people older than 65 years of age in the United States is expected to double. Heart disease is the leading cause of mortality in developed nations, including the United States. Due to the increased incidence of cardiac disease in elderly patients, the need for special treatment considerations, including cardiac devices, may be necessary to reduce morbidity and mortality in this patient population. The purpose of this review is to provide a primer of the common cardiac devices used in the management of cardiac disorders in the geriatric patient population. In order to do this, we have performed a literature review for articles related to cardiac devices published between 2000 and 2020, in addition to reviewing guidelines and recommendations from relevant professional societies. We provide readers with an overview of several cardiac devices including implantable loop recorders, pacemakers, cardiac resynchronization therapy, automated implantable cardiac defibrillators, watchman devices, and ventricular assist devices. Indications, contraindications, clinical trial data, and general considerations in the geriatric population were included. Due to the aging population and increased incidence of cardiac disease, clinicians should be aware of the indications and contraindications of cardiac device therapy in the management of various cardiac conditions that afflict the geriatric population.

BACKGROUND: Orthostatic hypotension (OH) is a potentially debilitating condition caused by dysfunction of the autonomic nervous system, which is essential for the physiologic response to orthostatic posture. In addition to OH, autonomic dysfunction may also be associated with the development of concurrent supine hypertension (SH). AREAS OF UNCERTAINTY: This paradoxical effect speaks to the complexity of the pathogenesis of autonomic disease and greatly complicates management of these patients. Clinicians are faced with a dilemma because aggressive treatment of orthostatic intolerance can worsen supine hypertension and attempts to control supine hypertension can worsen orthostatic intolerance. DATA SOURCES: Systematic review of the published literature. PREVENTION OF SUPINE HYPERTENSION: Patients should aim to avoid known stressors, perform physical maneuvers (eg, slowly getting up from bed, sleeping with head of bed elevated), manage underlying related conditions (eg, diabetes mellitus), and exercise. MANAGEMENT OF SUPINE HYPERTENSION: With failure of conservative management, patients may advance to pharmacologic therapy. It is important to understand the underlying suspected etiology of the syndrome of supine hypertension and OH (SH-OH) to select promising pharmacologic agents. This article reviews medical treatment options to work toward achieving a better quality of life for patients afflicted with this disease. Although clonidine and beta-blockers can be used to treat hypertension without causing significant hypotension, midodrine, pyridostigmine, and droxidopa may be helpful in preventing OH. CONCLUSION: The etiology and severity of autonomic dysfunction vary widely between patients, suggesting a need for an individualized treatment approach. Achieving perfect blood pressure control is not a realistic goal. Rather, treatment should be aimed at improving the patient's quality of life and decreasing their risk of injury and organ damage.

Vasovagal syncope (VVS) (or neurocardiogenic syncope) is a common clinical condition that is challenging to both physicians and patients alike. Severe episodes of recurrent syncope can result in physical injury as well as psychological distress. This article provides a brief overview of current management strategies and a detailed overview of therapeutic modalities such as closed loop stimulation (CLS) and cardioneuroablation (CNA).

BACKGROUND: Pacemaker implantation in the U.S. is rising due to an aging population. The aim of this analysis was to identify risk factors associated with increased mortality and complications in hospitalized patients requiring pacemaker implantation. METHODS: We performed a retrospective analysis using the National Inpatient Sample database, identifying hospitalized patients who underwent pacemaker implantation using International Classification of Disease, Tenth Revision, Clinical Modification codes. Independent predictors of inpatient mortality were identified using multivariate logistic regression analysis. RESULTS: There were 242,980 hospitalizations with pacemaker implantation during 2016 and 2017. The most frequently encountered indications for hospitalizations involving pacemaker insertion included sick sinus syndrome (SSS) (27.60%), complete atrioventricular (AV) block (21.57%), and second-degree AV block (7.83%). Chronic liver disease was associated with the highest adjusted odds of inpatient mortality (aOR = 5.76, 95% CI: 4.46 to 7.44, p < .001). Comorbid anemia had the highest statistically significant adjusted odds ratio (aOR) for predictors of post-procedural cardiac complications (aOR = 3.17, 95% CI: 2.81 to 3.58, p < .001). Mortality in hospitalized patients needing pacemaker implantation was 1.05%. About 3.36% of hospitalizations developed post procedural circulatory complications (PPCC), 2.45% developed sepsis, and 1.84% developed mechanical complications of cardiac electronic devices. CONCLUSIONS: We identified several predictors of inpatient mortality in hospitalized patients undergoing pacemaker implantation, including chronic liver disease, protein-calorie malnutrition, chronic heart failure, anemia, and history of malignancy. Anemia, chronic liver disease, and congestive heart failure were independent predictors of adverse outcomes in such patients.

PURPOSE: Using National Inpatient Database (NIS), comparison of clinical outcomes for patients primarily admitted for atrial fibrillation/flutter with and without a secondary diagnosis of amyloidosis was done. Inpatient mortality was the primary outcome and hospital length of stay (LOS), mean total hospital charges, odds of undergoing cardiac ablation, pharmacologic cardioversion, having a secondary discharge diagnosis of heart block, cardiogenic shock and cardiac arrest were secondary outcomes. METHODS: NIS database of 2016, 2017 was used for only adult hospitalizations with atrial fibrillation/flutter as principal diagnosis with and without amyloidosis as secondary diagnosis using ICD-10 codes. Multivariate logistic with linear regression analysis was used to adjust for confounders. RESULTS: 932,054 hospitalizations were for adult patients with a principal discharge diagnosis of atrial fibrillation/flutter. 830 (0.09%) of these hospitalizations had amyloidosis. Atrial fibrillation/flutter hospitalizations with co-existing amyloidosis have higher inpatient mortality (4.22% vs 0.88%, AOR: 3.92, 95% CI 1.81-8.51, p = 0.001) and likelihood of having a secondary discharge diagnosis of cardiac arrest (2.40% vs 0.51%, AOR: 4.80, 95% CI 1.89-12.20, p = 0.001) compared to those without amyloidosis. CONCLUSIONS: Hospitalizations of atrial fibrillation/flutter with co-existing amyloidosis have higher inpatient mortality and odds of having a secondary discharge diagnosis of cardiac arrest compared to those without amyloidosis. However, LOS, total hospital charges, likelihood of undergoing cardiac ablation, pharmacologic cardioversion, having a secondary discharge diagnosis of heart block and cardiogenic shock were similar between both groups.
RESUMO
INTRODUCTION: We previously reported on a subgroup of postural orthostatic tachycardia syndrome (POTS) patients who may also have features of neurocardiogenic syncope as well. In this subgroup of patients, we found syncope and presyncope were predominant clinical features. To understand the mechanism of syncope in this subgroup, we identified 39 patients who underwent loop recorder insertion. METHODS: We reviewed charts of 450 patients who had POTS and syncope seen at the University of Toledo Medical Center from 2003 to 2017. Thirty-nine patients had at least four episodes of syncope in the last 6 months and were included for this study. All of these patients had a prior evaluation with a Holter and an event monitor which were inconclusive. RESULTS: Thirty-nine patients, 33 (85%) women, aged 20-46 years, were included in this study. All patients demonstrated prolonged asystole (>6 seconds) or severe bradycardia (heart rate < 30 beats/min) during their syncope on implantable loop recorder (IRL). Fifteen patients demonstrated an asystole of >10 seconds and also had prolonged and convulsive syncope. All patients had abrupt syncope without any warning sign. All patients underwent dual-chamber pacemaker implantation using a closed loop stimulation algorithm. Syncope were completely eliminated in all patients following pacemaker implantation; however, they continued to have orthostatic tachycardia. CONCLUSION: POTS patients with unusually frequent syncope should be considered for ILR implantation if other monitoring modalities like 48-hour Holter monitor or event recorder are inconclusive. ILR may identify a subgroup of POTS patients who may benefit from pacemaker implantations.

Atrioventricular (AV) node ablation is a commonly performed procedure for patients with chronic drug refractory atrial fibrillation (AF) with episodes of rapid ventricular response. We report on a 72-year-old man who had difficulty managing chronic drug refractory AFs with frequent hospitalizations for rapid ventricular rate. The patient was taken to the electrophysiology laboratory for AV node ablation. Extensive mapping and localization techniques of the compact AV node and ablation in the region were unsuccessful. Subsequently, high-output His bundle pacing using 20 mA at 2 ms of output energy was performed in an attempt to localize the His bundle in areas where high-output pacing resulted in a narrower QRS complex. Further ablations in the areas where pacing produced a narrower QRS complex resulted in complete heart block. This case highlights the importance of using this simple pacing maneuver to achieve complete heart block in patients in whom standard strategies to localize and ablate the compact AV node are unsuccessful.

ST-segment elevation (STE) is a very rare complication observed during various cardiac ablation procedures. We report an interesting case of transient STE elevation by inter-atrial septal stretch during introduction of a multipolar mapping catheter during pulmonary vein isolation procedure. We also discuss various mechanisms for this observation.
RESUMO
Large-scale multi-hospital data on cardiac resynchronization therapy (CRT) device implantation in patients with chronic kidney disease (CKD) are currently lacking. The purpose of this study was to examine the incidence of CRT device implantation in patients hospitalized with CKD and the impact of CRT device implantation on hospital complications and outcomes. We analyzed the Nationwide Inpatient Sample from 2008-2014 to identify yearly trends in CRT device implantation during CKD hospitalizations. We compared CRT biventricular pacemakers (CRT-Ps) and CRT defibrillators (CRT-Ds). We also obtained rates of comorbidities and complications associated with CRT device implantations. From 2008-2014, the proportion of hospitalized patients with a concurrent diagnosis of CKD receiving CRT-P devices consistently went up from 2008 to 2014 (from 12.3% to 23.8%, P < .0001) compared to the number of hospitalized patients with a concurrent diagnosis of CKD receiving CRT-D devices, which showed a consistent downward trend (from 87.7% to 76.2%, P < .0001). During CKD hospitalizations, most CRT device implantations were performed in patients aged 65-84 years (68.6%) and in men (74.3%). The most common complication of CRT device implantation during hospitalizations involving CKD was hemorrhage or hematoma (2.7%). Patients hospitalized with CKD who developed any complication associated with CRT device implantation had 3.35-fold increased odds of mortality compared to those without complications (odds ratio, 3.35; 95% confidence interval, 2.18-5.16; P < .0001). In summary, this study shows that CRT-P implantations became more common in CKD patients, while the rate of CRT-D implantations decreased over time. Hemorrhage or hematoma was the most common complication (2.7%), and the mortality risk was increased by 3.35 times in patients who developed periprocedural complications.
RESUMO
Methylphenidate has been shown to be an effective therapy in patients with refractory neurocardiogenic syncope. However, the role of methylphenidate in patients suffering from postural orthostatic tachycardia (POTS) has not been reported. The study was approved by the institutional review board. A retrospective nonrandomized analysis was preformed on 24 patients evaluated at our autonomic center for POTS from 2003 to 2010. The diagnosis of POTS was based on patient history, physical examination, and response to head up tilt table testing. The mean follow-up period was 9 ± 3 months. The patients were included in the current study if they had a diagnosis of POTS with severe symptoms of orthostatic intolerance and were refractory to the commonly used medications. All of these patients were started on methylphenidate and the response to therapy was considered successful if it provided symptomatic relief. Twenty-four patients (age 28 ± 12, 20 women) met inclusion criterion for this study. The response to treatment was assed subjectively in each patient and was collected in a retrospective fashion from patient charts and physician communications. Four patients reported side effects in the form of nausea and 2 ultimately had to discontinue the treatment. Another 4 patients had a follow-up of less than 6 months. Thus, only 18 patients who received methylphenidate completed the follow-up of 6 months. Out of these 18 patients, 14 (77%) patients reported marked improvement in their symptoms. Nine out of 12 patients who had recurrent episodes of syncope reported no syncope at 6 months of follow-up. Fourteen (77%) patients reported marked improvement in their symptoms of fatigue and presyncope. Four patients continue to have symptoms of orthostatic intolerance and 3 continued to have recurrent episodes of syncope. Methylphenidate may be beneficial in patients with otherwise refractory postural tachycardia syndrome.

There have been reports on the use of octreotide in patients with orthostatic hypotension, postural tachycardia syndrome, and orthostatic syncope. However, there are little if any data on the use of octreotide in patients who have failed multiple other medications. This study was a retrospective chart analysis and was approved by our Institutional Review Board. A total of 12 patients were identified for inclusion in this study. The diagnosis of orthostatic intolerance was based on patient history, physical examination, and response to Head Up Tilt Table testing. These patients had failed multiple medications and were ultimately treated with octreotide. In a retrospective chart review, we collected data, including demographic information, presenting symptoms, laboratory data, tilt-table response, standing heart rate, standing blood pressure before and after treatment (wherever available), and treatment outcomes. Twelve patients aged 33 ± 18 years, eight (66.7%) females, were found to have symptoms of refractory orthostatic intolerance and failed multiple regimens of medication and were ultimately treated with octreotide administration. Five patients (41.7%) had demonstrated a postural tachycardia syndrome pattern, five (41.7%) a neurocardiogenic, and two (16.6%) a dysautonomic response on a Head Up Tilt Table. Symptoms of syncope and orthostatic palpitations improved in six (50%) of the patients. Standing heart rate was significantly reduced after octreotide administration (80 ± 8 versus 108 ± 13; P < 0.05). The standing systolic blood pressure was increased after octreotide administration (107 ± 26 versus 116 ± 22). Three patients (25%) reported complete elimination of syncope, whereas another three had reduction in the frequency of their syncope. However, symptoms of fatigue improved only in two (29%) of the seven patients. Octreotide may improve symptoms in some patients with refractory orthostatic intolerance.

Erythropoietin has been reported to improve symptoms of orthostatic intolerance in patients suffering from orthostatic hypotension. Previous reports on the use of erythropoietin in patients with postural orthostatic tachycardia (POTS) have included only a very small number of patients. In the current study, we report on the use of erythropoietin in patients with refractory POTS. The study was approved by the institutional review board. A retrospective nonrandomized analysis was performed on 39 patients evaluated at our autonomic center for POTS from 2003 to 2010. The diagnosis of POTS was based on patient history, physical examination, and response to head-up tilt-table testing. The mean follow-up period was 6 months. The patients were included in the current study if they had a diagnosis of POTS with severe symptoms of orthostatic intolerance and were refractory to the commonly used medications. All these patients were started on erythropoietin, and the response to therapy was considered successful if it provided symptomatic relief. We screened 200 patients with POTS and found 39 patients (age 33 ± 12, 37 females) to be eligible for inclusion in the current study. The response to the treatment was assessed subjectively in each patient and was obtained in a retrospective fashion from patient charts and physician communications. Eight (21%) patients demonstrated no improvement in symptoms after administration of erythropoietin. Three (8%) patients showed an improvement in symptoms of orthostatic intolerance of <3 months. Twenty-seven (71%) patients demonstrated sustained improvement in their symptoms of orthostatic intolerance at the mean follow-up of 6 months. Erythropoietin significantly improved sitting diastolic blood pressure but had no effect on other hemodynamic parameters. In a select group of POTS patients who are refractory to commonly used medications, erythropoietin may help improve symptoms of orthostatic intolerance.

Infection is a well-recognized complication that can occur after the implantation of cardiac devices such as pacemakers and implantable cardioverter defibrillators (ICDs). Reported infection rates after new device implantation are reported to be around 1%, while infection rates after device generator replacements are higher with a reported average of up to 4-5% per year. Here we report our experience using a modified plastic surgical technique for cardiac device wound closure designed to both reduce infections and enhance cosmetic outcomes. Patients were recruited from among those individuals undergoing routine cardiac device implantation (either new or replacement) at our institution. A total of 124 patients were included in the study. There were 74 women and 48 men, mean age 58 ± 16 years. There were 74 new pacemaker implants and 27 pacemaker generator replacements. There were 17 new ICD generator implants and 6 ICD generator reimplants. Mean follow-up time was 15 ± 16 months. During the follow-up period, there have been no device infections nor any wound dehiscences observed. Each patient felt that the scar was cosmetically acceptable. Two patients developed mild rashes to the clear plastic adhesive that resolved after removal. The modified wound closure technique described above appears to minimize cardiac device wound infections while facilitating cosmetically acceptable wound scar formation.
