Complications on the feeding artery after an arterio-venous fistula closure in patients after kidney transplantation - a national cohort study.

Background: Arteriovenous fistulas (AVFs) in kidney transplant recipients are sometimes closed, either as a policy or due to complications. We collected data on the incidence of complications after AVF closure in a national cohort of transplanted patients.

Methods: Patients who received a kidney transplant between 2000 and 2015 and had a functional AVF that was later ligated or extirpated were included.

Conventional and Novel Inflammatory Biomarkers in Chronic Heart Failure Patients with Atrial Fibrillation.

(1) Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased morbidity and mortality both in the general population and heart failure patients. Inflammation may promote the initiation, maintenance and perpetuation of AF, but the impact of inflammatory molecular signaling on the association between AF and heart failure remains elusive. (2) In 111 patients with chronic stable heart failure, baseline values of conventional (IL-6 and hsCRP) and selected novel inflammatory biomarkers (IL-10, IL-6/IL-10 ratio, orosomucoid and endocan) were determined.

Patch angioplasty carotid endarterectomy versus eversion carotid endarterectomy.

Objectives: To compare carotid endarterectomy patch angioplasty (p-CEA) with eversion carotid endarterectomy (e-CEA) and associated risks of early cardio-cerebrovascular complications.

Methods: The study was a prospective randomized single-blind trial, monocentric, clinically applicable, descriptive analytical and comparative. From June 2021 to June 2023, 62 consecutive patients with symptomatic and asymptomatic stenosis of the internal carotid artery, admitted to our department and randomized into two groups: carotid endarterectomy with patch angioplasty and eversion carotid endarterectomy.

Effects of Water-Based Exercise on Patients Older than 60 Years Undergoing Cardiac Rehabilitation after Coronary Intervention.

Cardiac rehabilitation (CR) plays a crucial role in managing patients who have undergone coronary intervention (CI) following acute myocardial infarction. While water-based exercise is gaining recognition as an exercise modality in this patient population, its impact on the subgroup of older adults remains unexplored. In this post hoc analysis, we investigated the effects of water-based exercise on adults older than 60 years undergoing CR after CI, comparing it to land-based exercise and a control group.

Stepwise transvenous lead extraction due to pacemaker pocket infection following lactational mastitis complicated with breast abscess.

Background: Lactational mastitis is a common painful and debilitating inflammation of breast tissue, generally treated conservatively or with pus puncture in case of breast abscess. However, treating mastitis in patients with implantable surgical material located in the affected breast region can be extremely challenging. We present an unusual case of lactational mastitis complicated by pacemaker pocket infection in a breastfeeding mother.

Rapidly Growing and Ruptured Great Saphenous Vein Aneurysm in a Liver Transplant Patient.

Venous aneurysms are rare vascular malformations that can lead to significant clinical complications, including thrombosis, pulmonary embolism, rupture, and even fatal outcomes when not promptly and adequately managed. This case report presents a liver transplant patient under immunosuppressive therapy who developed a rapidly progressing great saphenous vein aneurysm, ultimately requiring urgent surgical intervention due to acute bleeding from the ruptured aneurysm. Immunosuppression emerges as a potential key factor in the formation and rapid growth of the aneurysm, with the pathophysiological mechanism potentially involving increased expression of specific matrix metalloproteinases.

Common Complications and Cardiopulmonary Resuscitation in Patients with Left Ventricular Assist Devices: A Narrative Review.

Heart failure remains a major global burden regarding patients' morbidity and mortality and health system organization, logistics, and costs. Despite continual advances in pharmacological and resynchronization device therapy, it is currently well accepted that heart transplantation and mechanical circulatory support represent a cornerstone in the management of advanced forms of this disease, with the latter becoming an increasingly accepted treatment modality due to the ongoing shortage of available donor hearts in an ever-increasing pool of patients. Mechanical circulatory support strategies have seen tremendous advances in recent years, especially in terms of pump technology improvements, indication for use, surgical techniques for device implantation, exchange and explantation, and postoperative patient management, but not in the field of treatment of critically ill patients and those undergoing cardiac arrest.

Comparison of Procedural Sedation With Propofol and Dexmedetomidine During Transcatheter Aortic Valve Replacement Using the Transfemoral Approach.

Objectives: Although procedural sedation is an established method of anesthesia for transcatheter aortic valve replacement (TAVR), reliable evidence to guide the choice of a suitable sedative agent remains scarce. Accordingly, this trial aimed to compare the effect of procedural sedation with dexmedetomidine versus propofol on postoperative neurocognitive and related clinical outcomes in patients undergoing TAVR.

Design: Prospective, randomized, double-blind clinical trial.

Native valve endocarditis in a patient with autoimmune hepatitis on low dose systemic corticosteroids: A case report.

infectious endocarditis (IE) is a rare cause of culture-negative endocarditis. The main risk factors are severe immunosuppression and prosthetic heart valve. We describe a case of IE on a native mitral valve in a patient with autoimmune hepatitis in remission while on low dose corticosteroids.

Abdominal Stent-Graft Treatment of Ascending Aortic Pseudoaneurysm Following Transcatheter Aortic Valve Implantation.

An ascending aortic pseudoaneurysm is a potentially lethal complication in aortic procedures. We present a hybrid approach using surgical innominate artery access and the endovascular insertion of an abdominal stent-graft extension to successfully treat a zone 0 ascending aortic pseudoaneurysm in a patient with a prior valve-in-valve transcatheter aortic valve implantation.

Use of absorbable hemostat bolster for prevention of donor renal artery kinking in kidney transplant.

Transplant renal artery stenosis due to mechanical kinking is a rare but significant complication in kidney transplantation that can lead to graft dysfunction due to graft hypoperfusion, delayed graft function, or even global kidney infarction. When detected during surgery, re-anastomosis is usually performed after re-clamping, which inevitably prolongs the warm ischemia time, and increases the possibility of primary graft non-function. In this report, we describe a novel, noninvasive surgical technique whereby the donor renal artery is padded with absorbable hemostatic material (i.

The Effect of Aquatic Exercise Training on Heart Rate Variability in Patients with Coronary Artery Disease.

Aquatic exercise training is a relatively understudied exercise modality in patients with CAD; with the present study, we sought to compare the impact of short-term 14-day water- and land-based exercise training on heart rate variability (HRV). We randomized 90 patients after a recent CAD event (myocardial infarction and/or revascularization within 2 months prior to inclusion) to either (i) water-based or (ii) land-based exercise training (14 days, two 30 min sessions daily), or (iii) controls. Before and after the intervention period, all participants underwent 20 min 12-channel high-resolution ECG recordings with off-line HRV analysis, including conventional linear time- and frequency-domain analysis (using the Welch method for fast-Fourier transformation), and preselected non-linear analysis (Poincaré plot-derived parameters, sample entropy, and the short-term scaling exponent α1 obtained by detrended fluctuation analysis).

Altered Heart Rate Turbulence and Variability Parameters Predict 1-Year Mortality in Heart Failure with Preserved Ejection Fraction.

Background: Heart failure with preserved ejection fraction (HFpEF) is a complex and heterogeneous clinical syndrome. In the absence of effective and potent treatment strategies, the main challenge in HFpEF management remains the availability of strong predictors of unfavourable outcomes. In our study, we sought to evaluate the potential prognostic value of heart rate turbulence (HRT) and variability (HRV) parameters on mortality in ambulatory HFpEF patients.

Minimising radiation exposure in catheter ablation of ventricular arrhythmias.

Background: Conventional fluoroscopy guided catheter ablation (CA) is an established treatment option for ventricular arrhythmias (VAs). However, with the complex nature of most procedures, patients and staff bare an increased radiation exposure. Near-zero or zero-fluoroscopy CA is an alternative method which could substantially reduce or even eliminate the radiation dose.

Cerebral microemboli in mini-sternotomy compared to mini- thoracotomy for aortic valve replacement: a cross sectional cohort study.

Background: Recently adopted mini-thoracotomy approach for surgical aortic valve replacement has shown benefits such as reduced pain and shorter recovery, compared to more conventional mini-sternotomy access. However, whether limited exposure of the heart and ascending aorta resulting from an incision in the second intercostal space may lead to increased intraoperative cerebral embolization and more prominent postoperative neurologic decline, remains inconclusive. The aim of our study was to assess potential neurological complications after two different minimal invasive surgical techniques for aortic valve replacement by measuring cerebral microembolic signal during surgery and by follow-up cognitive evaluation.

Cardiac Melanoma Metastasis with ERBB2 Gene Amplification: A Potential for Future Targeted Therapy.

Cardiac tumors are rare, and their treatment differs interindividually regarding the histopathological proprieties and the stage of disease. Authors present a case of symptomatic cardiac melanoma metastasis that expressed an () gene amplification in a course of the disease that has not yet been reported. The frail patient with a history of pulmonary and renal carcinoma, was admitted to the hospital due to a symptomatic left atrial tumor mass.

Emergency veno-arterial extracorporeal membrane oxygenation (VA ECMO)-supported percutaneous interventions in refractory cardiac arrest and profound cardiogenic shock.

Aims: We investigated the spectrum of emergency veno-arterial extracorporeal membrane oxygenation (VA ECMO)-supported interventions including percutaneous coronary intervention (PCI), transcatheter aortic valve implantation (TAVI) and invasive electrophysiology (EP).

Methods And Results: Between June 2010 and February 2020, 52 consecutive patients underwent VA ECMO implantation for refractory cardiac arrest (E-CPR) and 78 for profound cardiogenic shock. Percutaneous interventions on VA ECMO included PCI (n = 29), TAVI (n = 4) and EP (n = 1).

Transvenous lead extraction outcomes using a novel hand-powered bidirectional rotational sheath as a first-line extraction tool in a low-volume centre.

Objectives: Extraction of cardiovascular implantable electronic devices in low-volume medical centres with limited clinical experience and an evolving lead extraction programme may be challenging. We aimed to evaluate the safety and efficacy of stepwise transvenous lead extraction (TLE) using a novel type of hand-powered rotational sheath as a first-line tool for extraction of chronically implanted devices in a single, low-volume centre.

Methods: Sixty-seven consecutive patients undergoing a TLE procedure using the novel Evolution® RL rotational sheath as the first-line extraction tool between 2015 and 2019 at our institution were enrolled in the study.

Pacemaker-generated stress fracture of the second rib: a case report.

Background: Pocket-related complications following the implantation of cardiovascular implantable electronic devices primarily include pocket hematoma, infection, skin erosion or decubitus, device migration, and Twiddler's syndrome, with other pathologies such as nerve impairment or bone lesions being extremely rarely encountered. We report a case of a 20-year old asthenic, non-athlete female patient presenting with a device-generated fracture of the second rib several months after sub-muscular permanent pacemaker implantation due to repeated bilateral pre-pectoral pocket infections.

Case Presentation: A 20-year old female patient was readmitted to our institution 9 months following sub-pectoral implantation of a permanent pacemaker, complaining of severe pocket-related pain, which arose spontaneously in the absence of direct trauma, intense physical activity or vigorous coughing, and was associated with normal day-to-day activity.

Effectiveness of wound infusion of 0.2% ropivacaine by patient control analgesia pump after minithoracotomy aortic valve replacement: a randomized, double-blind, placebo-controlled trial.

Background: Local anesthetic wound infusion has become an invaluable technique in multimodal analgesia. The effectiveness of wound infusion of 0.2% ropivacaine delivered by patient controlled analgesia (PCA) pump has not been evaluated in minimally invasive cardiac surgery.

Favorable Response to CD34+ Cell Therapy Is Associated with a Decrease of Galectin-3 Levels in Patients with Chronic Heart Failure.

Background: Galectin-3 plasma levels (gal-3) were shown to correlate with the scar burden in chronic heart failure (CHF) setting. As scar burden predicts response to stem cell therapy, we sought to explore a correlation between gal-3 and response to CD34+ cell transplantation in patients with CHF.

Methods: We performed a post hoc analysis of patients, enrolled in 2 prospective trials investigating the clinical effects of CD34+ cell therapy in patients with ischemic cardiomyopathy (ICMP) and nonischemic dilated cardiomyopathy (DCMP).

Endocan Is an Independent Predictor of Heart Failure-Related Mortality and Hospitalizations in Patients with Chronic Stable Heart Failure.

Background: Heart failure (HF) is characterized by unfavorable prognosis. Disease trajectory of HF, however, may vary, and risk assessment of patients remains elusive. In our study, we sought to determine the prognostic impact of endocan-a novel biomarker of endothelial dysfunction and low-grade inflammation-in patients with heart failure.
