Veno-arterial ECMO ventricular assistance as a direct bridge to heart transplant: A single center experience in a low-middle income country.

Introduction: The use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) as a direct bridge to heart transplantation (BTT) is not common in adults worldwide. BTT with ECMO is associated with increased early/mid-term mortality compared with other interventions. In low- and middle-income countries (LMIC), where no other type of short-term mechanical circulatory support is available, its use is widespread and increasingly used as rescue therapy in patients with cardiogenic shock (CS) as a direct bridge to heart transplantation (HT).

Pulmonary presentation and coil marcation of dirofilaria lung coin nodes - case report.

Clinicians face significant diagnostic challenges when dealing with nodal lesions of the lung. The majority of lung nodules are benign; however, a significant number can be cancerous. Dirofilaria infestation should also be considered in the differential diagnosis of nodal lung lesions.

How are the predictors of sudden death modified after septal myectomy surgery?

Background: Hypertrophic cardiomyopathy is a condition associated with an increased risk of sudden death compared to the general population. Extended septal myectomy surgery has been suggested to impact the reduction of sudden death events according to various publications. The aim of this study was to assess changes in the prevalence of sudden death predictors in a population of patients undergoing extended septal myectomy surgery.

[Impact of a multidisciplinary team "ECMO Team" on the prognosis of patients undergoing veno-arterial extracorporeal membrane oxygenation for refractory cardiogenic shock and cardiac arrest].

Objectives: Veno-arterial Extracorporeal membrane oxygenation (VA ECMO) is a salvage intervention in patients with cardiogenic shock (CS), and cardiac arrest (CA) refractory to standard therapies. The design of ECMO Teams has achieved the standardization of processes, although its impact on survival and prognosis is unknown.

Objective: We aimed to analyze whether the creation of an ECMO Team has modified the prognosis of patients undergoing VA ECMO for refractory CS or CA.

Multiparameters associated to successful weaning from VA ECMO in adult patients with cardiogenic shock or cardiac arrest: Systematic review and meta-analysis.

Venoarterial extracorporeal membrane oxygenation (VA ECMO) is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange for acute cardiorespiratory failure, including refractory cardiogenic shock (CS) and cardiac arrest (CA). Few studies have assessed predictors of successful weaning (SW) from VA ECMO. This systematic review and meta-analysis aimed to identify a multiparameter strategy associated with SW from VA ECMO.

Bilateral internal thoracic artery grafting in elderly patients: Any benefit in survival?

Objective: The purpose of the present study was to compare survival outcomes in propensity score-matched patients aged 70 years or greater receiving a bilateral internal thoracic artery graft with patients receiving a single internal thoracic artery graft.

Methods: Among 4083 consecutive patients with isolated coronary artery bypass grafting who underwent operation between January 2001 and December 2018, we identified 1300 patients aged 70 years or greater; of these, 968 received a bilateral internal thoracic artery (bilateral internal thoracic artery group) and 332 received a single internal thoracic artery (single internal thoracic artery group). Propensity score matching was used to reduce the preoperative patient differences.

Effects of levosimendan on weaning and survival in adult cardiogenic shock patients with veno-arterial extracorporeal membrane oxygenation: systematic review and meta-analysis.

Introduction: Veno-arterial extracorporeal membrane oxygenation may be used to support patients with refractory cardiogenic shock. Many patients can be successfully weaned, the ability of some medications to facilitate weaning from veno-arterial extracorporeal membrane oxygenation were reported. To date, there are limited studies investigating the impact of levosimendan on veno-arterial extracorporeal membrane oxygenation weaning.

Acute penetrating atherosclerotic ulcer of the ascending aorta.

A 67-year-old man presented with chest pain. Clinical examination revealed hypertension (160/90 mm Hg). Electrocardiogram indicated no acute coronary syndrome and cardiac enzymes were normal.

[Infective endocarditis due to non-HACEK gram-negative bacilli in a Level III cardiovascular center in Argentina (1998-2016)].

Non-HACEK Gram-negative bacilli are a rare cause of infective endocarditis. Epidemiological, diagnostic and prognostic aspects of this entity are little known, and there is limited experience. The aim of this study was to analyze the clinical, microbiological and in-hospital outcomes of non-HACEK Gram negative bacilli endocarditis and to compare them with those due to other microorganisms.

Surgical Treatment of Dysphagia Lusoria Caused by Right-Aortic Arch with Kommerell Diverticulum: Left Heart Bypass without Subclavian Revascularization.

The authors present the case of a 26-year-old patient suffering from dysphagia because of compression by a Kommerell diverticulum in right aortic arch anomaly. Open surgical arch and descending aorta replacement with left heart bypass without left subclavian artery reimplantation was performed.

[Off-pump coronary revascularization. Late survival].

Although randomized clinical trials have compared the short-term results of coronary revascularization with on-pump vs. off-pump, the long-term survival effect of off-pump coronary surgery has not been analyzed. The aim of this study was to compare the long-term survival of patients with coronary surgery with off-pump technique.

Myocardial Revascularization Exclusively With Bilateral Internal Thoracic Arteries in T-Graft Configuration: Effects on Late Survival.

Background: We studied long-term survival using bilateral internal thoracic artery (BITA) grafting in a T-configuration exclusively versus using single internal thoracic artery (SITA) grafting in patients with multivessel disease.

Methods: Consecutive coronary operations performed at a single center between 1996 and 2014 were reviewed. Long-term survival among patients receiving coronary revascularization exclusively with BITA grafting in a T-configuration (n = 2,098) versus SITA grafts plus other types of conduits (saphenous vein graft [SVG] and radial artery [RA]) grafts (n = 1,659).

Anti-inflammatory mechanism of action of azithromycin in LPS-stimulated J774A.1 cells.

Azithromycin is a macrolide antibiotic with well-described anti-inflammatory properties which can be attributed, at least partially, to its action on macrophages. We have previously shown, with 18 different macrolide molecules, that IL-6 and PGE₂ inhibition correlates with macrolide accumulation, as well as with their binding to phospholipids in J774A.1 cells.

Azithromycin drives in vitro GM-CSF/IL-4-induced differentiation of human blood monocytes toward dendritic-like cells with regulatory properties.

Azithromycin, a macrolide antibacterial, has been shown to modify the phenotype of macrophages. We have investigated whether azithromycin in vitro is able to modulate the differentiation of human blood monocytes to DCs. iA-DCs appear to have a unique phenotype, characterized by increased granularity, adherence, and a surface molecule expression profile similar to that of MDCs, namely, CD1a⁻CD14⁻CD71⁺CD209(high), as well as high CD86 and HLA-DR expression.

Azithromycin distinctively modulates classical activation of human monocytes in vitro.

Background And Purpose: Azithromycin has been reported to modify activation of macrophages towards the M2 phenotype. Here, we have sought to identify the mechanisms underlying this modulatory effect of azithromycin on human monocytes, classically activated in vitro.

Experimental Approach: Human blood monocytes were primed with IFN-γ for 24 h and activated with LPS for 24 h.
