AIMS: Surgical intervention is used to treat dynamic left ventricular outflow tract obstruction (LVOTO) in hypertrophic cardiomyopathy. This study assesses the effect of different surgical strategies on long-term mortality and morbidity. METHODS AND RESULTS: In total, 347 patients underwent surgical intervention for LVOTO (1988-2015). Group A (n = 272) underwent septal myectomy; Group B (n = 33), septal myectomy and mitral valve (MV) repair; Group C (n = 22), myectomy and MV replacement; and Group D (n = 20), MV replacement alone...

BACKGROUND: New-onset atrial fibrillation (AF) after coronary artery bypass graft (CABG) operation is associated with poorer survival. Blanket prophylaxis efforts have not appreciably decreased incidence, making targeted prevention for high-risk patients desirable. We compared predictive abilities of existing scores developed/used to predict adverse CABG outcomes (Society of Thoracic Surgeons' [STS] risk of mortality) or AF not associated with cardiac operation (the Cohorts for Heart and Aging Research in Genomic Epidemiology [CHARGE]-AF score, the CHA2DS2-VASc score), and a risk model for predicting postoperative AF following cardiac operations (POAF score), with age (the most consistently identified post-CABG AF risk factor)...

Background: Post-operative atrial fibrillation (POAF) occurs in 20-50% of patients amid post-operative stay after Cardiac Surgery. We intend to determine whether colchicine therapy in patients undergoing cardiac surgery is a cost-effective strategy for prevention of postoperative atrial fibrillation. To undertake cost utility analysis and calculate ICUR for colchicine therapy in these subgroup of patients. Design: Decision tree model to calculate the incremental cost utility ratio comparing two treatment strategies in patients undergoing cardiac surgery...

BACKGROUND: Uniportal video-assisted thoracoscopic surgery (VATS) is gaining popularity internationally, but remains an uncommon practice in the United States. One proposed benefit is a decrease in narcotic usage and peri-operative pain when compared to traditional multiple incision VATS. The purpose of this study was to determine the post-operative narcotic usage between patients undergoing anatomic lobectomy via traditional VATS as compared to patients undergoing uniportal VATS. METHODS: All consecutive patients undergoing anatomic lobectomy for presumed malignancy by a single surgeon at an academic medical institution were recorded between July 2013 and September 2015...

INTRODUCTION: ToF patients are at risk for ventricular deterioration at a relatively young age, which can be aggravated by AF development. Therefore, knowledge on AF development and its timespan of progression is essential to guide treatment strategies for AF. OBJECTIVE: We examined late post-operative AF onset and progression in ToF patients during long-term follow-up after ToF correction. In addition, co-existence of regular supraventricular tachyarrhythmias (SVT) and ventricular tachyarrhythmias (VTA) was analyzed...

Evaluating the clinicopathological features of patients receiving definitive treatment for esophageal cancer may facilitate the identification of patterns and factors associated with post-operative complications, and enable the development of a surveillance strategy for surviving patients at a higher risk of disease recurrence. In the present study, clinical data from 579 patients with esophageal cancer that underwent radical resection of esophagus were collected. These patients were admitted to two medical centers in Northwest China, and information regarding the presence or absence of basic chronic diseases and post-operative results were retrospectively analyzed...

BACKGROUND: Atrial fibrillation occurs frequently after open-heart surgery. It is associated with increased morbidity and mortality, longer hospital stays, and increased healthcare costs. Prophylactic administration of colchicine may mitigate post-operative atrial fibrillation (POAF). METHODS: We searched PubMed, ClinicalTrials.gov and CENTRAL databases to identify randomized controlled trials (RCTs) that; (1) compared prophylactic use of colchicine to placebo, or usual care, in patients with sinus rhythm who underwent elective open-heart surgery and (2) reported POAF-incidence...

Junctional ectopic tachycardia (JET) and atrial fibrillation (AF) occur in patients recovering from open-heart surgery (OHS). Pharmacologic treatment is used for the control of post-operative atrial arrhythmias (POAA), but is associated with side effects. There is a need for a reversible, modulated solution to rate control. We propose a non-pharmacologic technique that can modulate AV nodal conduction in a selective fashion. Ten mongrel dogs underwent OHS. Stimulation of the anterior right (AR) and inferior right (IR) fat pad (FP) was done using a 7-pole electrode...

BACKGROUND: Length of lines of conduction block (CB) during sinus rhythm (SR) at Bachmann's bundle (BB) is associated with atrial fibrillation (AF). However, it is unknown whether extensiveness of CB at BB represents CB elsewhere in the atria. We aim to investigate during SR 1) the spatial distribution and extensiveness of CB 2) whether there is a predilection site for CB and 3) the association between CB and incidence of post-operative AF. METHODS: During SR, epicardial mapping of the right atrium (RA), BB and left atrium was performed in 209 patients with coronary artery disease...

BACKGROUND: Dabigatran is a direct thrombin inhibitor with a favorable effectiveness and safety profile when compared to vitamin K antagonists, both in randomized trials and real world registries of atrial fibrillation patients. Yet, physicians' fear of high bleeding risk scenarios in daily clinical practice still precludes a more widespread use of oral anticoagulation. We hereby report a successful case of dabigatran reversal with the novel monoclonal antibody fragment idarucizumab in a patient undergoing heart transplantation...

Despite orthogeriatric management, 12% of the elderly experienced PUs after hip fracture surgery. PUs were significantly associated with a low albumin level, history of atrial fibrillation coronary artery disease, and diabetes. The risk ratio of death at 6 months associated with pressure ulcer was 2.38 (95% CI 1.31-4.32%, p = 0.044). INTRODUCTION: Pressure ulcers in hip fracture patients are frequent and associated with a poor outcome. An orthogeriatric management, recommended by international guidelines in hip fracture patients and including pressure ulcer prevention and treatment, could influence causes and consequences of pressure ulcer...

BACKGROUND: Data regarding new onset atrial fibrillation (nAF) in general, non-cardiac, intensive care unit (ICU) patients are limited. However, it has been suggested that nAF is associated with worse clinical outcome in these patients. OBJECTIVE: The purpose of the present work was to study the prognostic impact of nAF, in this setting. METHODS: We prospectively studied all patients admitted to a single ICU for a period of 12 months. Patients admitted for brief post-operative monitoring, patients with chronic, intermittent atrial fibrillation and atrial fibrillation present upon admission, were excluded...

While biomarkers have greatly impacted the diagnosis and management of myocardial infarction and heart failure, the use of biomarkers has been slow to permeate management of atrial fibrillation. Guideline recommendations on the use of biomarkers in atrial fibrillation were virtually nonexistent until the 2016 European Society of Cardiology guidelines on atrial fibrillation offered a class IIb recommendation to consider using biomarkers such as high-sensitivity troponin and natriuretic peptide to further refine stroke and bleeding risk in atrial fibrillation patients...

OBJECTIVE: Systemic inflammation is a recognised contributory factor in the pathogenesis of de novo post-operative atrial fibrillation after cardiac surgery. This study aims to determine whether serum soluble vascular endothelial cell adhesion molecule (sVCAM-1) may predict the onset of POAF in patients under going coronary artery bypass grafting. METHODS: 34 patients undergoing non-emergent, on-pump CABG were prospectively recruited. Plasma was obtained at 24 h pre-operatively and at 48 and 96 h post-operatively...

BACKGROUND: Post-operative atrial fibrillation (POAF) frequently occurs after cardiac surgery. However, the mechanisms of POAF have not been fully elucidated. We aimed to examine whether pre-operative atrial gene expression related to cardiac metabolism is changed in patients with POAF. METHODS: Right atrial tissue was obtained during surgery from 38 patients who underwent cardiac surgery from 2013 to 2015. Atrial expression levels were determined by reverse transcription polymerase chain reaction for the following genes: glucose transporter type 4, peroxisome proliferator-activated receptor-α, fatty acid translocase, carnitine palmitoyltransferase 1B, and fatty acid binding protein 3 (FABP3)...

Amiodarone-induced pulmonary toxicity (APT) is a severe side effect that can lead to lung fibrosis or fatal respiratory failure. Usually APT occurs during long term therapy after administration of prolonged loading doses or high cumulative doses. We present the case of a 58 year old woman who underwent thoracic surgery with lobe resection. She developed atrial fibrillation with hemodynamic-instability on the first post-operative day. We initiated amiodarone therapy and four days later she developed respiratory failure...

BACKGROUND: Medical complications and preexisting conditions frequently place the surgeon in the unenviable position of choosing between the serious and potentially life-threatening effects of thrombosis, or the issue of bleeding and surgical site complications. The aim of this research was to determine if health utility could be a consideration before choosing to therapeutically anticoagulate in the hip and knee arthroplasty patient. METHODS: The quantitative risks and effectiveness of treatment options for venous thromboembolism, atrial fibrillation, acute coronary syndromes, ischaemic stroke and mechanical heart valves were evaluated from previously published data...
