RESUMO
Obesity has become a worldwide public health issue. Many obese patients concomitantly suffer with heart failure with reduced ejection fraction. There have been reports of improvement in left ventricular systolic function following significant weight loss after bariatric surgery. We sought to investigate this phenomenon within our institution. This was a retrospective single-center analysis of patients conducted between 2010 and 2019. The study included patients with morbid obesity (body mass index >35 kg/m2 and an obesity-related comorbid condition, or a body mass index >40 kg/m2) and left ventricular systolic dysfunction. Analysis was performed based on systolic function recovery after bariatric surgery and advanced heart failure therapy. Of the 190 patients identified, 57 patients had a left ventricular ejection fraction of <40%. Twenty-two patients underwent bariatric surgery, of which at least 54.5% had systolic function recovery. Patients who had systolic function recovery after bariatric surgery were significantly older (51.58 years ± 10.48 vs 32.3 years ± 5.03, Pâ¯=â¯0.001). Older age and female sex were predictors of systolic function recovery. In patients with obesity and heart failure with reduced ejection fraction, weight loss following bariatric surgery was shown to be correlated with significant improvement in left ventricular systolic function.

Aims: The association between heart failure (HF) patients and the incidence of cancer is not well understood, with conflicting results to date. The aim of this meta-analysis was to evaluate whether patients with HF have a higher risk of developing cancer. Methods and results: We performed a systematic literature search using PubMed, Embase, and Scopus for relevant articles from inception until 10 December 2022. The primary clinical outcome was the incidence of cancer. Secondary endpoints were the incidence of breast cancer, lung cancer, haematological cancer, colorectal cancer, and prostate cancer. A total of 9 articles with 7 329 706 (515 041 HF vs. 6 814 665 non-HF) patients were involved in the analysis. The mean age of the patients in the HF and the non-HF groups was 69.06 and 66.76 years. The median follow-up duration was 6.7 years. The most common comorbidity among both groups includes diabetes mellitus (27.58 vs. 14.49%) and hypertension (81.46 vs. 57.38%). Patients with HF were associated with a significant increase in the incidence of cancer {hazard ratio [HR], 1.43 [95% confidence interval (CI): 1.21-1.68], P < 0.001}, breast cancer [HR, 1.28 (95% CI: 1.09-1.50), P < 0.001], lung cancer [HR, 1.89 (95% CI: 1.25-2.85), P < 0.001], haematological cancer [HR, 1.63 (95% CI: 1.15-2.33), P = 0.01], and colorectal cancer [HR, 1.32 (95% CI: 1.11-1.57), P < 0.001] compared with patients without HF. However, the incidence of prostate cancer was comparable between both groups [HR, 0.97 (95% CI: 0.66-1.43), P = 0.88]. Conclusion: This meta-analysis confirms that the state of HF is associated with a higher risk for incident cancer. These data may aid in raising awareness with physicians that cancer may develop in patients with prevalent heart failure and that early screening and evaluation may be useful in an early diagnosis of cancer.
RESUMO
BACKGROUND: Cardiovascular sequelae of coronavirus disease 2019 (COVID-19) infection have been explored by clinicians and researchers all over the world. OBJECTIVE: The purpose of this study was to evaluate the incidence of atrioventricular block (AV) in patients hospitalized for COVID-19 and its association between in-hospital morbidity and mortality. METHODS: In-hospital electrocardiograms (ECGs) of 438 patients were compared with their prior or baseline ECGs to ascertain the development of new onset AV block. Patients who developed new AV blocks were then followed at 30 and 90 days post-discharge to check for resolution of AV block. Demographic characteristics, clinical characteristics, and complications during their hospital stay were evaluated. Major complications including respiratory failure requiring oxygen supplementation and mechanical ventilation, sepsis, deep vein thrombosis, elevated troponins, hospital and intensive care unit (ICU) length of stay, as well as death were compared between those who developed new onset AV blocks and those who did not. RESULTS: Based on our single center study, the incidence of new onset AV blocks among patients admitted for COVID-19 during the study period was 5.5 cases per 100 patients. New onset AV blocks were not associated with longer hospital and ICU length of stay, increased intubation rates, or increased mortality. CONCLUSION: Although the development of a new onset AV block is most likely multifactorial and not solely due to COVID-19, it is still important for clinicians to be mindful about the possibility of developing symptomatic bradycardia and life-threatening arrhythmias in patients admitted for COVID-19. This can be achieved by appropriate rhythm monitoring in-patient but the need for a cardiac event monitor upon discharge is unlikely to be necessary. Careful history taking, including family and drug use history is also of great importance as emerging drug therapies for COVID-19 have potential arrhythmogenic effects.

RESUMO
The ideal antithrombotic therapy post transcatheter aortic valve replacement (TAVR) remains uncertain. We performed a network meta-analysis of RCTs to report the outcomes with various antithrombotic strategies to determine the optimal therapy. A systematic search of the PubMed/Medline and Cochrane databases was performed through January 6, 2022. The primary outcome was stroke and the secondary outcomes were major/life-threatening bleeding, myocardial infarction, all-cause mortality, and cardiac mortality. A network meta-analysis was conducted with a random-effects model. All analysis was carried out using R version 4.0.3. Six RCTs were included in the final analysis. SAPT when compared with DAPT was associated with a reduced risk of major or life-threatening bleeding [OR: 0.42; 95% CI: 0.25-0.70]. Other antithrombotic strategies were associated with similar odds of major and life-threatening bleeding post TAVR compared with DAPT. There was no difference in the incidence of stroke, myocardial infarction, all-cause and cardiac mortality between the various antithrombotic strategies post TAVR. The present analysis reported SAPT as the preferred antithrombotic regimen post TAVR compared with other regimens in patients who do not have other indications for anticoagulation. Additional studies such as ADAPT-TAVR, CLOE and ATLANTIS trials will further add to our understanding of the adequate antithrombotic regimen post TAVR in patients with otherwise no indication for anticoagulation.

BACKGROUND: Desmosomes are specialized intercellular adhesive junctions of cardiac and epithelial cells that provide intercellular mechanical coupling through glycoproteins, one of which is desmoglein (DSG). DSG-2 mutations are frequently associated with biventricular arrhythmogenic cardiomyopathy (ACM). We report a case of left-dominant ACM in a patient who initially was misclassified as dilated cardiomyopathy (DCM). CASE SUMMARY: A 28-year-old-woman was found to have a moderately reduced left ventricular (LV) systolic function and frequent premature ventricular contractions (PVCs). Targeted genetic testing revealed a heterozygous likely pathogenic variant associated with ACM in exon 15 of the DSG-2 gene (c.3059_3062del; p.Glu1020Alafs*18). Subsequent cardiac magnetic resonance (CMR) imaging showed epicardial and mid-myocardial fatty infiltration involving multiple LV wall segments, multiple areas of mid-myocardial fibrosis/scar, regional dyskinesis involving both ventricles, and an overall reduced left ventricular ejection fraction. The patient's right ventricular (RV) cavity size and overall RV systolic function were normal. Based on the patient's frequent PVCs, family history, fibrofatty myocardial replacement in multiple LV segments, and dyskinetic motion of multiple ventricular wall segments (predominantly affecting the LV), the patient was diagnosed with left-dominant ACM. DISCUSSION: Identifying a likely pathogenic mutation associated with ACM in a patient with ventricular arrhythmias and a family history of sudden cardiac death increased the possibility of ACM. Subsequent CMR imaging confirmed the diagnosis of left-dominant ACM by demonstrating regional biventricular dyskinesia and a characteristic pattern of fibrofatty myocardial replacement. Our case highlights the importance of targeted genetic testing and advanced cardiac imaging in distinguishing left-dominant ACM from DCM.
RESUMO
We present a case of transcatheter heart valve thrombosis in a 76-year-old man with paroxysmal atrial fibrillation on therapeutic anticoagulation with apixaban and polycythemia vera. The incidence of transcatheter heart valve thrombosis in patients with atrial fibrillation and on adequate anticoagulation is not well reported. (Level of Difficulty: Intermediate.).
RESUMO
BACKGROUND: Foreign object ingestion (FOI) and food bolus impaction (FBI) are common causes of emergent endoscopic intervention. The choice of sedation used is often dictated by physician experience. Many endoscopists frequently prefer to use monitored anesthesia care (MAC) and general anesthesia (GA) as opposed to conscious sedation (CS) due to the concern for inadequate airway protection. However, there is insufficient data examining the safety of different sedation modalities in emergent endoscopic management of FOI and FBI. AIM: To investigate the complication rates of emergent endoscopic extraction performed under different sedation modalities. METHODS: We conducted a retrospective chart review of patients presenting with acute FBI and FOI between 2010 and 2018 in two hospitals. A standardized questionnaire was utilized to collect data on demographics, endoscopic details, sedation practices, hospital stay and adverse events. Complications recognized during and within 24 h of the procedure were considered early, whereas patients presenting with a procedure-related adverse event within two weeks of the index event were considered delayed complications. Complication rates of patients who underwent emergent endoscopic retrieval were compared based on sedation types, namely CS, MAC and GA. Chi-square analysis and multiple logistic regression were used to compare complication rate based on sedation type. RESULTS: Among the 929 procedures analyzed, 353 procedures (38.0%) were performed under CS, 278 procedures (29.9%) under MAC and the rest (32.1%) under GA. The median age of the subjects was 52 years old, with 57.4% being male. The majority of the procedures (64.3%) were FBI with the rest being FOI (35.7%). A total of 132 subjects (14.2%) had chronic comorbidities while 29.0% had psychiatric disorders. The most commonly observed early complications were mucosal laceration (3.8%) and bleeding (2.6%). The most common delayed complication was aspiration pneumonia (1.8%). A total of 20 patients (5.6%) could not adequately be sedated with CS and had to be converted to MAC or GA. Patient sedated with MAC and GA were more likely to require hospitalization, P < 0.0001. Analysis revealed no statistically significant difference in the complication rate between patients sedated under CS (14.7%), MAC (14.7%) and GA (19.5%), P = 0.19. CONCLUSION: For patients who present with FOI or FBI and undergo emergent endoscopic treatment, there is no significant difference in adverse event rates between CS, MAC and GA.
