© 2019 The Authors European Journal of Heart Failure © 2019 European Society of Cardiology, Recent evidence suggests comparable in‐hospital and long‐term outcomes between takotsubo syndrome (TTS) and acute coronary syndrome. Medical scoring systems are practical tools for decision making and prognostic assessment. However, TTS‐specific scoring systems for risk stratification have not yet been established. Recently, classification based on triggering conditions proved useful in predicting adverse outcomes in TTS (InterTAK Classification).1 Since clinical parameters other than triggering conditions can be associated with adverse outcomes in TTS, such as systolic blood pressure and heart rate, the present study aimed to establish a scoring system combining triggering factors with other important but easily‐ obtainable clinical parameters of daily clinical practice., C.T. has been supported by the H.H.

The percutaneous epicardial approach has become an adjunctive tool for electrophysiologists to treat disparate cardiac arrhythmias, including accessory pathways, atrial tachycardia, and particularly ventricular tachycardia. This novel technique prompted a strong impulse to perform epicardial access as an alternative strategy for pacing and defibrillation, left atrial appendage exclusion, heart failure with preserved ejection fraction, and genetically engineered tissue delivery. However, because of the incremental risk of major complications compared with stand-alone endocardial ablation, it is still practiced in a limited number of highly experienced centers across the world.

Catastrophic antiphospholipid antibody syndrome (CAPS) is a rare form of antiphospholipid syndrome, an autoimmune condition characterized by vascular thromboses, pregnancy loss, and antiphospholipid (aPL) antibodies. Diagnosis of CAPS relies on thrombosis of at least three different organs systems over 1 week, histopathological evidence of small vessel occlusion, and high aPL antibody titers. In a subset of precipitating circumstances, activation or disruption of endothelial cells in the microvasculature may occur along with cardiomyopathy. We present two cases of CAPS-associated dilated cardiomyopathy at our institution, focusing on disease management, pathophysiology, and treatment. These patients were of Southeastern Asian descent, raising the possibility of genetic polymorphisms contributing to the development of cardiomyopathy. Both met CAPS criteria and both demonstrated clinicopathologic thrombotic microangiopathy (TMA) and complement activation and developed severe dilated cardiomyopathy with shock. Complement activation plays an important role in the development of CAPS and may be important in the pathogenesis of CAPS-associated cardiomyopathy. Clinical suspicion for TMA as a pathophysiologic mechanism of unexplained heart failure in CAPS is important and increased awareness of cardiac side effects is necessary so that early treatment can be initiated to halt further cardiac and systemic complications.

This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License., Aims: Acute pulmonary disorders are known physical triggers of takotsubo syndrome (TTS). This study aimed to investigate prevalence of acute pulmonary triggers in patients with TTS and their impact on outcomes. Methods and results: Patients with TTS were enrolled from the International Takotsubo Registry and screened for triggering factors and comorbidities. Patients were categorized into three groups (acute pulmonary trigger, chronic lung disease, and no lung disease) to compare clinical characteristics and outcomes. Of the 1670 included patients with TTS, 123 (7%) were identified with an acute pulmonary trigger, and 194 (12%) had a known history of chronic lung disease. The incidence of cardiogenic shock was highest in patients with an acute pulmonary trigger compared with those with chronic lung disease or without lung disease (17% vs. 10% vs. 9%, P = 0.017). In-hospital mortality was also higher in patients with an acute pulmonary trigger than in the other two groups, although not significantly (5.7% vs. 1.5% vs. 4.2%, P = 0.13). Survival analysis demonstrated that patients with an acute pulmonary trigger had the worst long-term outcome (P = 0.002). The presence of an acute pulmonary trigger was independently associated with worse long-term mortality (hazard ratio 2.12, 95% confidence interval 1.33-3.38; P = 0.002). Conclusions: The present study demonstrates that TTS is related to acute pulmonary triggers in 7% of all TTS patients, which accounts for 21% of patients with physical triggers. The presence of acute pulmonary trigger is associated with a severe in-hospital course and a worse long-term outcome., C. T. has been supported by the H.H.

However, ethnic disparities in takotsubo syndrome (TTS) remain elusive. This study assessed differences in clinical characteristics between Japanese and European TTS patients and determined the impact of ethnicity on in-hospital outcomes. Methods: TTS patients in Japan were enrolled from 10 hospitals and TTS patients in Europe were enrolled from 32 hospitals participating in the International Takotsubo Registry. Clinical characteristics and in-hospital outcomes were compared between Japanese and European patients. Results: A total of 503 Japanese and 1670 European patients were included. Japanese patients were older (72.6 ± 11.4 years vs. 68.0 ± 12.0 years; p < 0.001) and more likely to be male (18.5 vs. 8.4%; p < 0.001) than European TTS patients. Physical triggering factors were more common (45.5 vs. 32.0%; p < 0.001), and emotional triggers less common (17.5 vs. 31.5%; p < 0.001), in Japanese patients than in European patients. Japanese patients were more likely to experience cardiogenic shock during the acute phase (15.5 vs. 9.0%; p < 0.001) and had a higher in-hospital mortality (8.2 vs. 3.2%; p < 0.001). However, ethnicity itself did not appear to have an impact on in-hospital mortality. Machine learning approach revealed that the presence of physical stressors was the most important prognostic factor in both Japanese and European TTS patients. Conclusion: Differences in clinical characteristics and in-hospital outcomes between Japanese and European TTS patients exist. Ethnicity does not impact the outcome in TTS patients. The worse in-hospital outcome in Japanese patients, is mainly driven by the higher prevalence of physical triggers., Open Access funding provided by Universität Zürich.

Background Prognosis of Takotsubo syndrome (TTS) remains controversial due to scarcity of available data. Additionally, the effect of the triggering factors remains elusive. Objectives This study compared prognosis between TTS and acute coronary syndrome (ACS) patients and investigated short- and long-term outcomes in TTS based on different triggers. Methods Patients with TTS were enrolled from the International Takotsubo Registry. Long-term mortality of patients with TTS was compared to an age- and sex-matched cohort of patients with ACS. In addition, short- and long-term outcomes were compared between different groups according to triggering conditions. Results Overall, TTS patients had a comparable long-term mortality risk with ACS patients. Of 1,613 TTS patients, an emotional trigger was detected in 485 patients (30%). Of 630 patients (39%) related to physical triggers, 98 patients (6%) had acute neurologic disorders, while in the other 532 patients (33%), physical activities, medical conditions, or procedures were the triggering conditions. The remaining 498 patients (31%) had no identifiable trigger. TTS patients related to physical stress showed higher mortality rates than ACS patients during long-term follow-up, whereas patients related to emotional stress had better outcomes compared with ACS patients. Conclusions Overall, TTS patients had long-term outcomes comparable to age- and sex-matched ACS patients. Also, we demonstrated that TTS can either be benign or a life-threating condition depending on the inciting stress factor. We propose a new classification based on triggers, which can serve as a clinical tool to predict short- and long-term outcomes of TTS.

Aims The aim of the present study was to investigate the impact of aspirin on prognosis in takotsubo syndrome (TTS). Methods and results Patients from the International Takotsubo (InterTAK) Registry were categorized into two groups based on aspirin prescription at discharge. A comparison of clinical outcomes between groups was performed using an adjusted analysis with propensity score (PS) stratification; results from the unadjusted analysis were also reported to note the effect of the PS adjustment. Major adverse cardiac and cerebrovascular events (MACCE: a composite of death, myocardial infarction, TTS recurrence, stroke or transient ischaemic attack) were assessed at 30-day and 5-year follow-up. A total of 1533 TTS patients with known status regarding aspirin prescription at discharge were included. According to the adjusted analysis based on PS stratification, aspirin was not associated with a lower hazard of MACCE at 30-day [hazard ratio (HR) 1.24, 95% confidence interval (CI) 0.50-3.04, P = 0.64] or 5-year follow-up (HR 1.11, 95% CI 0.78-1.58, P = 0.58). These results were confirmed by sensitivity analyses performed with alternative PS-based methods, i.e. covariate adjustment and inverse probability of treatment weighting. Conclusion In the present study, no association was found between aspirin use in TTS patients and a reduced risk of MACCE at 30-day and 5-year follow-up. These findings should be confirmed in adequately powered randomized controlled trials. ClinicalTrials.gov Identifier: NCT01947621.

Objective: Takotsubo syndrome (TTS) is characterized by acute left ventricular dysfunction, which can contribute to intraventricular thrombus and embolism. Still, prevalence and clinical impact of thrombus formation and embolic events on outcome of TTS patients remain unclear. This study aimed to investigate clinical features and outcomes of patients with and without intraventricular thrombus or embolism. Additionally, factors associated with thrombus formation or embolism, as well as predictors for mortality, were identified. Approach and Results: TTS patients enrolled in the International Takotsubo Registry at 28 centers in Australia, Europe, and the United States were dichotomized according to the occurrence/absence of intraventricular thrombus or embolism. Patients with intraventricular thrombus or embolism were defined as the ThrombEmb group. Of 1676 TTS patients, 56 (3.3%) patients developed intraventricular thrombus and/or embolism following TTS diagnosis (median time interval, 2.0 days [range, 0–38 days]). Patients in the ThrombEmb group had a different clinical profile including lower left ventricular ejection fraction, higher prevalence of the apical type, elevated levels of troponin and inflammatory markers, and higher prevalence of vascular disease. In a Firth bias-reduced penalized-likelihood logistic regression model apical type, left ventricular ejection fraction ≤30%, previous vascular disease, and a white blood cell count on admission >10×10 3 cells/μL emerged as independent predictors for thrombus formation or embolism. Conclusions: Intraventricular thrombus or embolism occur in 3.3% of patients in the acute phase of TTS. A simple risk score including clinical parameters associated with intraventricular thrombus formation or embolism identifies patients at increased risk.

We sought to investigate the clinical predictors and prognostic impact of recovery time for TTS patients. Methods and Results: TTS patients from the International Takotsubo Registry were included in this study. Cut‐off for early LV recovery was determined to be 10 days after the acute event. Multivariable logistic regression was used to assess factors associated with the absence of early recovery. In‐hospital outcomes and 1‐year mortality were compared for patients with versus without early recovery. We analyzed 406 patients with comprehensive and serial imaging data regarding time to recovery. Of these, 191 (47.0%) had early LV recovery and 215 (53.0%) demonstrated late LV improvement. Patients without early recovery were more often male (12.6% versus 5.2%; P=0.011) and presented more frequently with typical TTS (76.3% versus 67.0%, P=0.040). Cardiac and inflammatory markers were higher in patients without early recovery than in those with early recovery. Patients without early recovery showed unfavorable 1‐year outcome compared with patients with early recovery (P=0.003).

Copyright © 2020 European Society of Cardiology, Aims: Takotsubo syndrome (TTS) is an acute heart failure syndrome, which shares many features with acute coronary syndrome (ACS). Although TTS was initially described with angiographically normal coronary arteries, smaller studies recently indicated a potential coexistence of coronary artery disease (CAD) in TTS patients. This study aimed to determine the coexistence, features, and prognostic role of CAD in a large cohort of patients with TTS. Methods and results: Coronary anatomy and CAD were studied in patients diagnosed with TTS. Inclusion criteria were compliance with the International Takotsubo Diagnostic Criteria for TTS, and availability of original coronary angiographies with ventriculography performed during the acute phase. Exclusion criteria were missing views, poor quality of angiography loops, and angiography without ventriculography. A total of 1016 TTS patients were studied. Of those, 23.0% had obstructive CAD, 41.2% had non-obstructive CAD, and 35.7% had angiographically normal coronary arteries. A total of 47 patients (4.6%) underwent percutaneous coronary intervention, and 3 patients had acute and 8 had chronic coronary artery occlusion concomitant with TTS, respectively. The presence of CAD was associated with increased incidence of shock, ventilation, and death from any cause. After adjusting for confounders, the presence of obstructive CAD was associated with mortality at 30 days. Takotsubo syndrome patients with obstructive CAD were at comparable risk for shock and death and nearly at twice the risk for ventilation compared to an age- and sex-matched ACS cohort. Conclusions: Coronary artery disease frequently coexists in TTS patients, presents with the whole spectrum of coronary pathology including acute coronary occlusion, and is associated with adverse outcome.

Background Clinical characteristics and outcomes of takotsubo syndrome (TTS) patients with malignancy have not been fully elucidated. This study sought to explore differences in clinical characteristics and to investigate short‐ and long‐term outcomes in TTS patients with or without malignancy. Methods and Results TTS patients were enrolled from the International Takotsubo Registry. The TTS cohort was divided into patients with and without malignancy to investigate differences in clinical characteristics and to assess short‐ and long‐term mortality. A subanalysis was performed comparing long‐term mortality between a subset of TTS patients with or without malignancy and acute coronary syndrome (ACS) patients with or without malignancy. Malignancy was observed in 16.6% of 1604 TTS patients. Patients with malignancy were older and more likely to have physical triggers, but less likely to have emotional triggers compared with those without malignancy. Long‐term mortality was higher in patients with malignancy (P, See Editorial Angelini and Uribe

Aims We aimed to evaluate the frequency, clinical features, and prognostic implications of cardiac arrest (CA) in takotsubo syndrome (TTS). Methods and results We reviewed the records of patients with CA and known heart rhythm from the International Takotsubo Registry. The main outcomes were 60-day and 5-year mortality. In addition, predictors of mortality and predictors of CA during the acute TTS phase were assessed. Of 2098 patients, 103 patients with CA and known heart rhythm during CA were included. Compared with patients without CA, CA patients were more likely to be younger, male, and have apical TTS, atrial fibrillation (AF), neurologic comorbidities, physical triggers, and longer corrected QT-interval and lower left ventricular ejection fraction on admission. In all, 57.1% of patients with CA at admission had ventricular fibrillation/tachycardia, while 73.7% of patients with CA in the acute phase had asystole/pulseless electrical activity. Patients with CA showed higher 60-day (40.3% vs. 4.0%, P Conclusions Cardiac arrest is relatively frequent in TTS and is associated with higher short- and long-term mortality. Clinical and electrocardiographic parameters independently predicted mortality after CA.

This is an open access article under the terms of the Creative Commons Attribution‐NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes., Background Atrial fibrillation (AF) is a major risk factor for mortality. The prevalence, clinical correlates, and prognostic impact of AF in Takotsubo syndrome (TTS) have not yet been investigated in a large patient cohort. This study aimed to investigate the prevalence, clinical correlates, and prognostic impact of AF in patients with TTS. Methods and Results Patients with TTS were enrolled from the International Takotsubo Registry, which is a multinational network with 26 participating centers in Europe and the United States. Patients were dichotomized according to the presence or absence of AF at the time of admission. Of 1584 patients with TTS, 112 (7.1%) had AF. The mean age was higher (P

The clinical course of takotsubo syndrome (TTS) can be complicated by several life-threatening conditions. In particular, cardiogenic shock (CS) represents one of the leading causes of mortality in the acute phase and occurs in a considerable number of patients with TTS, with an incidence of ≈10%. At present, no established guidelines are available to support specific treatment recommendations,and the conventional therapy for CS leads to uncertain results in TTS cases. The International Takotsubo Registry (www.takotsubo-registry.com) is an observational, prospective, and retrospective registry established at the University Hospital Zurich in 2011, with the largest TTS database worldwide. Patients were included in the registry between 2011 and 2017 based on modified Mayo Clinic Diagnostic criteria. Hospitalization data were recorded through standardized forms on admission or during revision of clinical charts; follow-up data were obtained from medical records, telephone follow-up, or clinical visits. The study population was categorized into 2 groups: patients with TTS with and without CS. The study protocol was reviewed by the respective local ethics committees or investigational review boards at each collaboration site. Where informed consent was required, formal written consent was obtained from patients.

Patients with pes planovalgus deformity often have coexisting spring ligament pathology. A primary repair of the ligament may fail during weightbearing due to chronic degeneration of the ligamentous tissue. Augmentation with a suture tape has been suggested to strengthen the repair. Limited data exist regarding flatfoot reconstruction with augmented spring ligament repair using a suture tape. This is a review of 57 consecutive patients who had flatfoot reconstruction with concomitant spring ligament augmented repair between July 2014 and August 2017. Weightbearing radiographic parameters were obtained preoperatively and compared to radiographs at an average time of 62 ± 46.5 (range 20-220) weeks postoperative. Significant improvements were seen in the radiographic parameters evaluated. Five patients had subsequent operations including one deep infection, 2 hardware removals remote to the spring ligament augmentation, 1 ankle arthrodesis, and 1 triple arthrodesis. Concomitant spring ligament repair augmented with a suture tape was a safe procedure that contributed to radiographic correction in a consecutive series of 57 patients undergoing flatfoot deformity correction.

A select 10-30% of patients with recurrent lateral ankle sprains develop chronic ankle instability (CAI). Patients with chronic ankle instability describe a history of the ankle “giving way” with or without pathological laxity on examination. Evaluation includes history, identification of predisposing risk factors for recurrent sprains, and the combination of clinical tests (eg, laxity tests) with imaging to establish the diagnosis. There are a variety of nonoperative strategies to address chronic ankle instability, which include rehabilitation and taping or bracing to prevent future sprains. Patients who fail conservative treatment are candidates for surgery. The anatomic approaches (eg, modified Broström) are preferred to nonanatomic procedures since they recreate the ankle’s biomechanics and natural course of the attenuated ligaments. There is a growing interest in minimally invasive procedures via ankle arthroscopy that also address the associated intra-articular disorders. This article provides a review of chronic lateral ankle instability consisting of relevant anatomy, associated disorders, evaluation, treatment methods, and complications.Level of Evidence:Level V, expert opinion.

Tendon grafts are often utilized for reconstruction of the lateral ligaments unamenable to primary repair. However, tendon and ligaments have different biological roles. The anterior tibiofibular ligament’s (ATiFL) distal fascicle may be resected without compromising the stability of the ankle joint. The aim of this study is to describe an all-arthroscopic and intra-articular surgical technique of ATiFL’s distal fascicle transfer for the treatment of chronic ankle instability. Five unpaired cadaver ankles underwent arthroscopic ATiFL’s distal fascicle transfer using a non-absorbable suture and a knotless anchor. Injured or absent ATiFL’s distal fascicle were excluded from the study. Following arthroscopy, the ankles were dissected and evaluated for entrapment of nearby adjacent anatomical structures. The ligament transfer was also assessed. The distance between the anterolateral (AL) portals and the superficial peroneal nerve (SPN) was measured and the shortest distance was reported. All specimens revealed successful transfer of the tibial origin of the ATiFL’s distal fascicle onto the talar insertion of anterior talofibular ligament’s (ATFL) superior fascicle. The fibular origin of the ATiFL’s distal fascicle remained intact. There were no specimens with SPN or extensor tendon entrapment. The median distance between the proximal AL portal and SPN was 3.8 mm. The median distance between the distal AL portal and SPN was 3.9 mm. An all-arthroscopic approach to an ATiFL’s distal fascicle transfer is a reliable method to reconstruct the ATFL’s superior fascicle. Transfer of ATiFL’s distal fascicle avoids the need for tendon harvest or allograft. The lack of injury to nearby adjacent structures suggests that it is a safe procedure. The clinical relevance of the study is that ATiFL’s distal fascicle can be arthroscopically transferred to be used as a biological reinforcement of the ATFL repair, or as an ATFL reconstruction.

Aims Clinical presentation of takotsubo syndrome (TTS) mimics acute coronary syndrome (ACS) and does not allow differentiation. We aimed to develop a clinical score to estimate the probability of TTS and to distinguish TTS from ACS in the acute stage. Methods and results Patients with TTS were recruited from the International Takotsubo Registry ( www.takotsubo-registry.com) and ACS patients from the leading hospital in Zurich. A multiple logistic regression for the presence of TTS was performed in a derivation cohort (TTS, n = 218; ACS, n = 436). The best model was selected and formed a score (InterTAK Diagnostic Score) with seven variables, and each was assigned a score value: female sex 25, emotional trigger 24, physical trigger 13, absence of ST-segment depression (except in lead aVR) 12, psychiatric disorders 11, neurologic disorders 9, and QTc prolongation 6 points. The area under the curve (AUC) for the resulting score was 0.971 [95% confidence interval (CI) 0.96–0.98] and using a cut-off value of 40 score points, sensitivity was 89% and specificity 91%. When patients with a score of ≥50 were diagnosed as TTS, nearly 95% of TTS patients were correctly diagnosed. When patients with a score ≤31 were diagnosed as ACS, ∼95% of ACS patients were diagnosed correctly. The score was subsequently validated in an independent validation cohort (TTS, n = 173; ACS, n = 226), resulting in a score AUC of 0.901 (95% CI 0.87–0.93). Conclusion The InterTAK Diagnostic Score estimates the probability of the presence of TTS and is able to distinguish TTS from ACS with a high sensitivity and specificity.

Category: Ankle; Trauma Introduction/Purpose: Syndesmotic disruption occurs in 10 to 13% of all ankle fractures. It is present in 15 cases per 100,000 of the general population. There has been debate on the best treatment for syndesmotic injuries. The typical surgical treatments include fixation with either screws or suture button devices. The purpose of this study is to compare clinical outcomes of syndesmotic injuries treated surgically with either screws or suture button devices. It was hypothesized that suture button fixation would provide equal clinical results with less need for hardware removal. Methods: This was a multi-center, randomized, prospective clinical trial comparing two surgical interventions for treatment of acute syndesmotic injury. Subjects were placed into either screw fixation or the Suture-button device group. Subjects with clinical signs or radiographic evidence of syndesmotic injury were asked to participate in this study. Inclusion criteria was ages 18 to 65 years old with confirmed syndesmotic instability. The primary outcomes of the study were VAS scores (activity, pain, satisfaction) and FFI scores (pain, disability, activity) which were collected at preoperative state, 6 weeks, and 12 months postoperatively. Results: Sixty-five subjects were enrolled in this study. Thirty-two subjects received Suture-button fixation (49%) and 33 received screw fixation (51%). VAS scores and FFI scores for subjects treated with the Suture-button device or screw fixation comparing preoperative, six-week, and 12-month scores all showed clinical improvement. There was no significant difference between the two treatment groups (p >0.05).Nine subjects (27%) in the syndesmotic screw fixation group experienced adverse events, and only one subject (3%) in the suture-button group had adverse event. Conclusion: The short-term clinical outcomes suggest that both syndesmotic screws and suture-button devices are effective treatment options to address acute syndesmotic injuries. In the short-term (12-months), suture-button fixation resulted in significantly less adverse events compared to syndesmotic screw fixation group.

AIMS The aim of the present study was to analyze gender disparities in a large cohort of acute coronary syndrome (ACS) patients from the Zurich Acute Coronary Syndrome (Z-ACS) Registry. METHODS Gender disparities in ACS were examined. The primary endpoint included in-hospital death rate, and the secondary endpoint major adverse cardiac and cerebrovascular events (MACCEs) at 30-day follow-up. Furthermore, independent predictors for MACCEs and death were identified. RESULTS In total, 2612 patients with ACS were identified. Out of these, 23% were women. The mean age was higher in women (68.6 ± 12.2; P < 0.001). Troponin-T on admission (1.33 ± 4.64 vs. 1.19 ± 3.04 μg/l; P = 0.002) and N-terminal of the prohormone brain natriuretic peptide on admission (3456.2 ± 7286.7 vs. 1665.6 ± 4800.6 ng/l; P < 0.001) were higher in women compared with men. Single-vessel disease was more common in women (44.9 vs. 39.7%; P = 0.023) and, conversely, multivessel disease was more prevalent in male patients as compared with their female counterparts (59.4 vs. 54.4%; P = 0.029). At discharge, men were more likely prescribed statins (89.4 vs. 85.2%; P = 0.004). Overall mortality and MACCEs were similar for both genders. In women, peak creatine kinase and peak C-reactive protein emerged as independent predictors for MACCEs and SBP on admission, and maximal C-reactive protein and use of glycoprotein IIb/IIIa inhibitors (GPIIb/IIIa) as strong independent predictors for in-hospital death. CONCLUSION The present results suggest a closing gap in short-term outcome and improvement in cardiac care between women and men. Nonetheless, differences in treatment strategies continue to exist, particularly pertaining to statin regimens at discharge, which might potentially have a powerful impact on long-term outcomes and gender disparities.

We present a case of a 48-year-old female who developed myocarditis and near fatal arrhythmias during high dose Il-2 therapy for metastatic renal cancer. On day 5 of therapy, the patient developed sudden onset chest pain, elevated cardiac enzymes and ST segment changes on EKG. Coronary angiogram was normal, however echocardiogram showed reduced ejection fraction and hemodynamic measurements showed elevated bilateral elevated filling pressures. The patient then developed episodes of recurrent ventricular arrhythmia, precipitated by bradycardia and PVC, requiring defibrillation and temporary pacemaker placement. Endomycardial biopsy was nonspecific showing fibrosis with subsequent cardiac MRI showed evidence of myocardial edema, consistent with Il-2 induced myocarditis in the setting of no prior cardiac history. After the discontinuation of Il-2 therapy, the patient displayed clinical improvement as well as improved ejection fraction. This case brings attention to the cardiac toxicities associated with high dose Il-2 therapy including potentially lethal arrhythmias and highlights the importance of careful cardiac screening prior to initiation of treatment.

Malignant pleural effusions are common complications in patients with primary or metastatic cancer to the lungs. In this article, we describe a unique case of a patient with history of diffuse pulmonary metastases from gallbladder adenocarcinoma who acutely developed a bilious pleural effusion following endoscopic retrograde cholangiopancreatography. We believe the bilious pleural effusion (cholethorax or bilothorax) developed as a complication of endoscopic retrograde cholangiopancreatography rather than tumor burden causing a fistula from the biliary tree to the right pleural space. We discuss possible mechanisms of formation of the bilious pleural effusion in our patient and present a literature review of previously reported cases of bilious pleural effusions.

This report presents a case of tacrolimus cardiotoxicity in an adult patient who received tacrolimus immunosuppression for orthotopic liver transplant (OLT). Tacrolimus-associated cardiotoxicity has been described in the literature, however this is the first case to document the development of a dilated cardiomyopathy in a patient shortly after initiating tacrolimus therapy post transplant. With the growing use of tacrolimus in transplant medicine, this case report expands the literature of tacrolimus cardiotoxicity and can aid clinicians in the evaluation and management of patients exposed to this form of immunosuppression.

Category: Flatfoot reconstruction Introduction/Purpose: Adult acquired flatfoot often results from posterior tibial tendon dysfunction followed by attenuation of the ligamentous support of the medial longitudinal arch of the foot. The spring ligament is the strongest ligamentous support for the talonavicular joint making it a viable target for flatfoot reconstruction procedures. There are concerns that direct repair of the spring ligament complex could result in failure as the already attenuated tissues of the ligament stretch out with mobilization and weight bearing. Suture tape augmentation of ligament repairs has shown greater loads to failure in biomechanical testing; however, there is a paucity of data surrounding clinical and radiographic outcomes of flatfoot reconstruction with augmented spring ligament repair. Methods: A retrospective review was performed of patients who underwent flatfoot reconstruction including spring ligament repair with suture tape augmentation between July 2014 and August 2017. Weight bearing radiographs were obtained for all patients both pre-operatively and at their last available follow-up. All radiographs were assessed by two surgeons for validated radiographic parameters including AP talocalcaneal angle, AP talo-first metatarsal angle, AP talar uncoverage, lateral talocalcaneal angle, lateral talo-first metatarsal (Meary) angle, lateral medial cuneiform-fifth metatarsal height, and lateral calcaneal pitch. Paired sample T-tests were used to compare pre-operative and post-operative radiographic measurements to assess for correction of these parameters. Results: 57 patients met inclusion criteria. The average time to final radiographic evaluation was 47 weeks (10 to 200 weeks). All radiographic parameters assessed showed significant correction when compared to pre-operative measurements. The average correction for each parameter included 6.02 degrees for AP talocalcaneal angle (pConclusion: Reconstruction of adult acquired flatfoot with spring ligament repair using suture tape augmentation is a safe procedure that resulted in significant weight bearing radiographic correction at an average of 47 weeks follow-up.

Tricuspid atresia is typically corrected in the neonatal period. Without palliation only half of patients survive childhood, and of those, many develop Eisenmenger's syndrome or heart failure. We present a 38-year-old adult female with uncorrected tricuspid atresia with ventriculo-arterial

Spindle-cell sarcomas of the heart are exceedingly rare, with fewer than 10 cases reported in the literature. Spindle cell carcinoma of soft tissue has a poor prognosis, with 1, 3 and 5-year survival rates of 46%, 22% and 17%. Surgical resection is the only definitive treatment. A 47-year-old

We present a rare case of acute febrile neutrophilic dermatosis, also known as Sweet syndrome, associated with recurrence of metastatic cervical cancer. This report highlights similar reports and serves as an important reminder of the relationship between Sweet syndrome and cervical cancer. Increasing awareness of Sweet syndrome assists clinicians in recognizing characteristic findings and encourages evaluation of patients for new-onset or recurrent neoplastic disease. Additionally, we discuss the typical presentation of the syndrome, the proper workup and treatment, and a common pitfall encountered in the diagnosis of Sweet syndrome.

Apical ballooning is broadly recognized as the classic form of takotsubo syndrome (TTS). Atypical subtypes of TTS also exist, which constitute about 20% of all cases. To date, clinical profile and course of atypical TTS types have rarely been studied.To characterize the clinical profile and outcomes of typical vs atypical types of TTS in a large patient cohort.Records of 1750 patients from the International Takotsubo Registry, comprising 26 participating cardiovascular centers in 9 different countries, were reviewed and data on clinical profile and outcomes collected from January 1, 2011, to December 31, 2014.Clinical characteristics and in-hospital as well as long-term outcomes were assessed.Of 1750 patients diagnosed with TTS between 1998 and 2014, a total of 1430 (81.7%) presented with apical TTS (defined as typical TTS) and 320 (18.3%) with midventricular, basal, or focal TTS (all defined as atypical TTS). Patients with atypical TTS were younger than those with typical TTS (mean [SD], 62.5 [13.3] vs 67.3 [12.9] years; P .001). Brain natriuretic peptide levels on admission were lower (median factor increase of the upper limit of normal, 4.18 vs 6.59; P = .02) and left ventricular ejection fraction was higher (mean [SD], 43.4% [10.7%] vs 40.6% [12.0%]; P .001) in patients with atypical than those with typical forms of TTS. ST-segment depression was more prevalent in patients with atypical TTS (31 of 286 [10.8%] vs 90 of 1292 [7.0%]; P = .03), while ST-segment elevation was found more frequently in patients with typical TTS (593 of 1292 [45.9%] vs 97 of 286 [33.9%]; P .001). Patients with atypical TTS more often had neurologic disorders than those with typical TTS (81 of 274 [29.6%] vs 286 of 1251 [22.9%]; P = .02). While in-hospital mortality was comparable between patients with atypical and typical TTS (10 of 320 [3.1%] vs 62 of 1430 [4.3%]; P = .32), the atypical forms showed a favorable outcome at 1 year (P = .01). However, after adjustment for confounders, only left ventricular ejection fraction less than 45%, atrial fibrillation, and neurologic disease, but not the type of TTS, were independent predictors. After 1 year, patients with both types of TTS showed a similar prognosis at long-term follow-up.Atypical TTS has different characteristics than typical TTS, including younger age of onset, more frequent ST-segment depression, higher prevalence of neurologic diseases, less pronounced reduction in left ventricular ejection fraction, and lower brain natriuretic peptide values on admission. Outcomes are comparable between patients with both types after adjustment for confounders, suggesting that both should be equally monitored.

T helper type 17 (Th17) cells have been characterized based on production of interleukin-17 (IL-17) and association with autoimmune diseases. We studied the role of Th17 cells in aplastic anemia (AA) by isolating Th17 cells from patients blood (n = 41) and bone marrow (BM) mononuclear cells (n = 7). The frequency and total number of CD3+CD4+IL-17–producing T cells were increased in AA patients at presentation compared with healthy controls (P = .0007 and .02, respectively) and correlated with disease activity. There was an inverse relationship between the numbers of Th17 cells and CD4+CD25highFoxP3+ regulatory T cells (Tregs) in the blood of AA patients. Concomitant with the classical Th1 response, we detected the presence of CD4+ and CD8+ IL-17-producing T cells in a mouse model of lymph node infusion–induced BM failure. Although anti–IL-17 treatment did not abrogate BM failure, early treatment with the anti–IL-17 antibody reduced the severity of BM failure with significantly higher platelet (P < .01) and total BM cell (P < .05) counts at day 10. Recipients that received anti-IL-17 treatment had significantly fewer Th1 cells (P < .01) and more Treg cells (P < .05) at day 10 after lymph node infusion. Th17 immune responses contribute to AA pathophysiology, especially at the early stage during disease progression.

To our knowledge, atypical Hemolytic Uremic Syndrome (aHUS) causing myocarditis in adults has not been previously reported. A 33 year-old female with a history of Kikuchi disease and immune thrombocytopenia was admitted for cholangitis. A CT Abdomen showed biliary ductal dilation as well as a small

Long-term outcomes of patients with Takotsubo syndrome (TTS) remains a controversial issue given scarcity of data. Additionally, a novel classification system is needed to further predict outcomes based on the triggering event. Patients were selected from the International Takotsubo Registry (

Aims Takotsubo syndrome (TTS) is typically provoked by negative stressors such as grief, anger, or fear leading to the popular term 'broken heart syndrome'. However, the role of positive emotions triggering TTS remains unclear. The aim of the present study was to analyse the prevalence and characteristics of patients with TTS following pleasant events, which are distinct from the stressful or undesirable episodes commonly triggering TTS. Methods and results Takotsubo syndrome patients with preceding pleasant events were compared to those with negative emotional triggers from the International Takotsubo Registry. Of 1750 TTS patients, we identified a total of 485 with a definite emotional trigger. Of these, 4.1% (n = 20) presented with pleasant preceding events and 95.9% (n = 465) with unequivocal negative emotional events associated with TTS. Interestingly, clinical presentation of patients with 'happy heart syndrome' was similar to those with the 'broken heart syndrome' including symptoms such as chest pain [89.5% (17/19) vs. 90.2% (412/457), P = 1.0]. Similarly, electrocardiographic parameters, laboratory findings, and 1-year outcome did not differ. However, in a post hoc analysis, a disproportionate higher prevalence of midventricular involvement was noted in 'happy hearts' compared with 'broken hearts' (35.0 vs. 16.3%, P = 0.030). Conclusion Our data illustrate that TTS can be triggered by not only negative but also positive life events. While patient characteristics were similar between groups, the midventricular TTS type was more prevalent among the 'happy hearts' than among the 'broken hearts'. Presumably, despite their distinct nature, happy and sad life events may share similar final common emotional pathways, which can ultimately trigger TTS. OA hybrid - CA extern

Carcinoid tumors are rare and slow-growing neuroendocrine tumors. In the United States, the prevalence is reported at 2 cases per 100,000 persons. The classic carcinoid syndrome occurs in up to 5% of cases and its vasoactive effects can induce flushing, secretory diarrhea, bronchospasm and hypotension1. Carcinoid induced cardiac dysfunction is rare and involves development of plaques on the tricuspid and pulmonic valves, often manifesting as tricuspid insufficiency and pulmonic stenosis (TIPS). More specifically, these plaques cause hemodynamic dysfunction as a result of thickening and restricted motion of the valve leaflets. Of all cardiac carcinoid cases, the left-heart valves are affected in less than 10% of cases, due to atrial right-to-left shunt or primary bronchial carcinoid. Despite appropriate valve replacement therapy, rarely does the subsequent congestive heart failure resolve; necessitating an ongoing balance between cardiac treatment options and chemotherapy. Herein, we present a case of aggressive carcinoid heart disease manifesting as left-sided valvular plaque with subsequent development of severe tricuspid valve regurgitation after triple-valve replacement surgery. We will also review the treatment strategy in this patient with aggressive carcinoid syndrome.

BACKGROUND: The natural history, management, and outcome of takotsubo (stress) cardiomyopathy are incompletely understood. METHODS: The International Takotsubo Registry, a consortium of 26 centers in Europe and the United States, was established to investigate clinical features, prognostic predictors, and outcome of takotsubo cardiomyopathy. Patients were compared with age- and sex-matched patients who had an acute coronary syndrome. RESULTS: Of 1750 patients with takotsubo cardiomyopathy, 89.8% were women (mean age, 66.8 years). Emotional triggers were not as common as physical triggers (27.7% vs. 36.0%), and 28.5% of patients had no evident trigger. Among patients with takotsubo cardiomyopathy, as compared with an acute coronary syndrome, rates of neurologic or psychiatric disorders were higher (55.8% vs. 25.7%) and the mean left ventricular ejection fraction was markedly lower (40.7±11.2% vs. 51.5±12.3%) (P

The Watchman device is a transcatheter left atrial appendage (LAA) occluding device used in patients with nonvalvular atrial fibrillation (NVAF) and a high CHADS2-VA2SC score who are poor long-term anticoagulation candidates. Pericardial effusion related to device deployment and perforation can be a life-threatening complication. While not common in hands of experienced operators, management may require surgical intervention. Here we present a rare case of LAA perforation, which was corrected by successful repositioning of the device foregoing the need for surgical management.

Background: Clinical presentation of takotsubo syndrome (TTS) mimics acute coronary syndrome (ACS) and does not allow differentiation. We aimed to develop a clinical score to estimate the probability of TTS and to distinguish TTS from ACS in the acute stage. Methods: TTS patients were recruited
