Coronary atherosclerotic plaque phenotype and physiopathologic mechanisms: Is there an influence of sex? Insights from intracoronary imaging.

Coronary artery disease (CAD) is the leading cause of disability and death in both women and men; considerable differences in clinical presentation, natural history and prognosis are reported between sexes. Different pathophysiological mechanisms play a major role, including sex-related and gender-related features or a combination of both. Reports from intracoronary imaging studies pointed towards morphological plaque features, which seemed to differ between men and women, albeit results reported so far were not conclusive.

Precipitating factors in patients with spontaneous coronary artery dissection: Clinical, laboratoristic and prognostic implications.

Background: Spontaneous coronary artery dissection (SCAD) often presents with acute coronary syndrome and underlying pathophysiology involves the interplay between predisposing factors and precipitating stressors, such as emotional and physical triggers. In our study we sought to compare clinical, angiographic and prognostic features in a cohort of patients with SCAD according to the presence and type of precipitating stressors.

Methods: Consecutive patients with angiographic evidence of SCAD were divided into three groups: patients with emotional stressors, patients with physical stressors and those without any stressor.

A case of thrombotic thrombocytopenic purpura associated with COVID-19.

Acquired thrombotic thrombocytopenic purpura (TTP) is an autoimmune disease that can be triggered by different events, including viral infections. It presents as thrombotic microangiopathy and can lead to severe complications that often require management in the intensive care unit (ICU). We report a patient who presented with acquired TTP following COVID-19 infection.

Systemic thromboembolism from a misdiagnosed non-bacterial thrombotic endocarditis in a patient with lung cancer: A case report.

Thromboembolic events are frequent in patients with cancer, commonly involving the venous and pulmonary circulation. The arterial system is rarely implicated in embolism and, when involved, a cardiogenic origin should always be excluded. In the present study, a case of a patient who developed multiple embolic events concomitantly with the diagnosis of locally-advanced non-small cell lung cancer with high expression levels of programmed death-ligand 1 (PD-L1) in >50% of tumor cells is reported.

Left ventricular free-wall rupture, a potentially lethal mechanical complication of coronaric angioplasty : an unusual case report.

The incidence of complications of coronary perforation varied significantly among studies probably due to population heterogeneity and interventional techniques applied in each centre. Free wall rupture, cardiac tamponade and miocardial infarction are the most  feared. The treatment of perforation remains a challenge of every cath- lab team.

The aim of this retrospective multicenter registry study was to investigate age-dependent trends in mortality, long-term survival, and comorbidity over time in patients who underwent isolated CABG from 2003 to 2015. The percentage of patients < 60 years of age was 18.9%.

Randomized, multicenter trial of lateral Trendelenburg versus semirecumbent body position for the prevention of ventilator-associated pneumonia.

Purpose: The lateral Trendelenburg position (LTP) may hinder the primary pathophysiologic mechanism of ventilator-associated pneumonia (VAP). We investigated whether placing patients in the LTP would reduce the incidence of VAP in comparison with the semirecumbent position (SRP).

Methods: This was a randomized, multicenter, controlled study in invasively ventilated critically ill patients.

Coronary Artery Bypass Grafting with Arterial Conduits in the Elderly.

Although improved long-term outcomes obtained with the use of arterial grafts for coronary revascularization in comparison with the traditional association of a single arterial and saphenous vein grafts have been demonstrated in the overall population, the efficacy of this newer technique in the elderly is difficult to prove because their shorter life expectancy due to advanced heart disease, associated with severe comorbidities. Moreover, more widespread use of this technique is limited by the concerns on the potential morbidity, particularly the longer time required to perform the operation and the possibility of deep sternal wound infection in case of bilateral internal thoracic artery harvesting due to the decreased blood supply to the sternum and surrounding tissues.The review of the recent literature indicates that the use of bilateral internal thoracic arteries in very elderly patients should not be considered routinely.

Venoarterial extracorporeal membrane oxygenation after coronary artery bypass grafting: Results of a multicenter study.

Background: The evidence of the benefits of using venoarterial extracorporeal membrane oxygenation (VA-ECMO) after coronary artery bypass grafting (CABG) is scarce.

Methods: We analyzed the outcomes of patients who received VA-ECMO therapy due to cardiac or respiratory failure after isolated CABG in 12 centers between 2005 and 2016. Patients treated preoperatively with ECMO were excluded from this study.

Purpose: The aim of this study was to compare the success rate and safety of short-axis versus long-axis approaches to ultrasound-guided subclavian vein cannulation.

Methods: A total of 190 patients requiring central venous cannulation following cardiac surgery were randomized to either short-axis or long-axis ultrasound-guided cannulation of the subclavian vein. Each cannulation was performed by anesthesiologists with at least 3 years' experience of ultrasound-guided central vein cannulation (>150 procedures/year, 50% short-axis and 50% long-axis).

Parma tracheostomy technique: a hybrid approach to tracheostomy between classical surgical and percutaneous tracheostomies.

Background: The aim of our study is to compare the classical surgical tracheostomy (TT) technique with a modified surgical technique designed and created by the cardiothoracic surgery staff of our department to reduce surgical trauma and postoperative complications. This modified technique combines features of percutaneous TT and surgical TT avoiding the use of specialized tools, which are required in percutaneous TT.

Methods: From October 2008 to March 2014 we performed 67 tracheostomies using this New Modified Surgical Technique (NMST) and 56 TT with the Classical Surgical Technique (CST).

Randomized Evidence for Reduction of Perioperative Mortality: An Updated Consensus Process.

Objective: Of the 230 million patients undergoing major surgical procedures every year, more than 1 million will die within 30 days. Thus, any nonsurgical interventions that help reduce perioperative mortality might save thousands of lives. The authors have updated a previous consensus process to identify all the nonsurgical interventions, supported by randomized evidence, that may help reduce perioperative mortality.

Surgical treatment for functional ischemic mitral regurgitation: current options and future trends.

There is an increasing number of patients with mitral regurgitation secondary to dilated cardiomyopathy. Ischemic mitral regurgitation is a common complication of left ventricular dysfunction related to chronic coronary artery disease: it is present in 10-20% of these patients and is associated with a worse prognosis also after coronary revascularization. Currently, coronary artery bypass grafting combined with restrictive annuloplasty is the most commonly performed surgical procedure, although novel approaches have been used with varying degrees of success.

Correlation between quality of cardiopulmonary resuscitation and self-efficacy measured during in-hospital cardiac arrest simulation; preliminary results.

Background: The concept of self-assess it's a central mechanism in human agency for behavior change and should translate to desirable practice patterns. There are no many studies that have investigated the relationship between the perception of the ability to perform cardiopulmonary resuscitation (CPR) and the quality of the same. The aim of this work is to investigate the relation between physiological and psychosocial variables in cardiac resuscitation in order to improve the involvement and motivation of professionals in training courses.
