Transcutaneous Hitching Sutures in Paediatric Minimally Invasive Surgery: A Novel Technique of "Assistant Without Port".

BACKGROUND: Transcutaneous hitching sutures in paediatric minimally invasive surgery (MIS) is a unique and rare technique. This technique has been used previously in adult patients undergoing gastric resections and laparoscopic cholecystectomy; however, its use in paediatric population has never been reported in the world literature. The primary objective of this study was to bring out the advantages and feasibility of this technique in minimally invasive gastrointestinal, hepatobiliary, urological and thoracoscopic surgeries on paediatric patients. MATERIALS AND METHODS: This retrospective observational study was conducted on 167 paediatric patients who underwent MIS surgery for different indications between April 2016 and March 2020 at two paediatric surgery tertiary care centres. RESULTS: A total of 167 patients, including 91 boys and 76 girl patients between the age group of new-born period to 12 years were operated. The mean hospital stay was 4 days. Five out of 167 cases (3%) had post-operative surgical emphysema, which resolved spontaneously. At 6-month follow-up, parental satisfaction was 100%, and in 99% of patients, scars were imperceptible. CONCLUSION: This versatile technique is of exemplary utility, especially in paediatric patients where there is a paucity of working space at low intra-abdominal pressure, and eases the dissection even in narrow and closed spaces with a better functional and cosmetic outcome.

Digitally enabled acute care for atrial fibrillation: conception, feasibility and early outcomes of an AF virtual ward.

BACKGROUND: Atrial fibrillation (AF) represents a growing healthcare challenge, mainly driven by acute hospitalisations. Virtual wards could be the way forward to manage acute AF patients through remote monitoring, especially with the rise in global access to digital telecommunication and the growing acceptance of telemedicine post-COVID-19. METHODS: An AF virtual ward was implemented as a proof-of-concept care model. Patients presenting acutely with AF or atrial flutter and rapid ventricular response to the hospital were onboarded to the virtual ward and managed at home through remote ECG-monitoring and 'virtual' ward rounds, after being given access to a single-lead ECG device, a blood pressure monitor and pulse oximeter with instructions to record daily ECGs, blood pressure, oxygen saturations and to complete an online AF symptom questionnaire. Data were uploaded to a digital platform for daily review by the clinical team. Primary outcomes included admission avoidance, readmission avoidance and patient satisfaction. Safety outcomes included unplanned discharge from the virtual ward, cardiovascular mortality and all-cause mortality. RESULTS: There were 50 admissions to the virtual ward between January and August 2022. Twenty-four of them avoided initial hospital admission as patients were directly enrolled to the virtual ward from outpatient settings. A further 25 readmissions were appropriately prevented during virtual surveillance. Patient satisfaction questionnaires yielded 100% positive responses among participants. There were three unplanned discharges from the virtual ward requiring hospitalisation. Mean heart rate on admission to the virtual ward and discharge was 122±26 and 82±27 bpm respectively. A rhythm control strategy was pursued in 82% (n=41) and 20% (n=10) required 3 or more remote pharmacological interventions. CONCLUSION: This is a first real-world experience of an AF virtual ward that heralds a potential means for reducing AF hospitalisations and the associated financial burden, without compromising on patients' care or safety.

A comparison of clinical outcomes following atrial fibrillation ablation for heart failure patients with preserved or reduced left ventricular function: A systematic review and meta-analysis.

BACKGROUND: This review aims to determine if patients who undergo atrial fibrillation (AF) ablation with heart failure with preserved ejection fraction (HFpEF) do better, or worse or the same compared to patients with heart failure with reduced ejection fraction (HFrEF). METHODS: A search of MEDLINE and EMBASE was performed using the search terms: "atrial fibrillation", "ablation" and terms related to HFpEF and HFrEF in order to identify studies that evaluated one or more of i) AF recurrence, ii) periprocedural complications and iii) adverse outcomes at follow up for patients with HFpEF and HFrEF who underwent AF ablation. Data was extracted from included studies and statistically pooled to evaluate adverse events and AF recurrence. RESULTS: 5 studies were included in this review and the sample size of the studies ranged from 91 to 521 patients with heart failure. There was no significant difference in the pooled rate for no AF or symptom recurrence after AF ablation comparing patients with HFpEF vs HFrEF (RR 1.07 95%CI 0.86-1.33, p = 0.15). The most common complications were access site complications/haematoma/bleeding which occurred in similar proportion in each group; HFpEF (3.1%) and HFrEF (3.1%). In terms of repeat ablations, two studies were pooled to yield a rate of 78/455 (17.1%) for HFpEF vs 24/279 (8.6%) for HFrEF (p = 0.001. CONCLUSIONS: Heart failure patients with preserved or reduced ejection fraction have similar risk of AF or symptom recurrence after AF ablation but two studies suggest that patients with HFpEF are more likely to have repeat ablations.

Revisiting the risks of incident atrial fibrillation: a narrative review. Part 2.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia with increasing incidence worldwide. Much focus has been directed towards AF prevention, given the morbidity and mortality from stroke, heart failure, and dementia. There are a number of common conditions associated with the onset of AF including, but not limited to, increased alcohol consumption, body weight, exercise, and stress. To reduce the incidence of AF, public health campaigns and targeted patient interventions may be warranted to promote balanced alcohol intake, appropriate exercise, and stress management to prevent AF and associated comorbidity. In this narrative review, we consider the evidence linking these risk factors with AF, putative mechanisms underlying the association, and whether risk factor modification may reduce AF burden.

Revisiting the risks of incident atrial fibrillation: a narrative review. Part 1.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. Much focus has been directed towards AF prevention, given the morbidity, mortality, and financial cost to health care systems associated with this arrhythmia. There are a number of common conditions associated with the onset of AF, but not only limited to hypertension, diabetes, or smoking. As we understand the factors associated with incident AF, public health campaigns and targeted patient interventions are warranted to promote blood pressure control, glycemic control in patients with diabetes, smoking cessation to prevent AF, and associated comorbidity. In this narrative review, we consider some of the evidence linking these risk factors with AF. We additionally examine the role of risk factor modification in reducing AF burden. In Part 1 we address the evidence for hypertension, diabetes, and smoking as risk factors for incident AF.
