Predictors and Prognostic Impact of In-hospital Bleeding after Transcatheter Aortic Valve Replacement According to BARC and VARC-2 Definitions
Abstract Pulmonary endarterectomy is a curative procedure for chronic thromboembolic Pulmonary Hypertension. As usual, cardiopulmonary bypass circuit is required. However, there are several complications attributed to extracorporeal circulation. Hemodilution, systemic inflammatory response syndrome and leukocyte sequestration are circulation related complications. The severe forms include Acute Respiratory Distress Syndrome, Acute Lung Injury, myocardial stunning, dysfunction of the right ventricle, coagulopathy, postoperative stroke or renal dysfunction. In this case report, we aimed to give information about perioperativ...

A Blood Filter Fights Deadly Inflammatory Response
A new blood filtration technology may prove to be life-saving for patients whose normally healthy inflammatory response to injury or illness has gone into overdrive, resulting in fatally high levels of cytokines in their blood. In an interview with MD+DI, Dr. Phillip Chan, MD, PhD, CEO of CytoSorbents Corp., explained that inflammation, and the production of substances called cytokines that drive inflammation, are the body’s natural response to heal injury or infection. But sometimes, the inflammatory response is so severe in such conditions as sepsis and infection, burn injuries, trauma, pancreatitis, li...

“A contemporary description of staphylococcus aureus prosthetic valve endocarditis. Differences according to the time elapsed from surgery”
Staphylococcus aureus prosthetic valve endocarditis (SAPVE) has a poor prognosis. There are no large series that accurately describe this entity. This is a retrospective observational study on a prospective cohort from 3 Spanish reference hospitals for cardiac surgery, including 78 definitive episodes of left SAPVE between 1996 and 2016. Fifty percent had a Charlson Index score>5; 53% were health care-related. Twenty percent did not present fever. Complications at diagnosis included: severe heart failure (HF, 29%), septic shock (SS, 17.9%), central nervous system abnormalities (19%), septic metastasis (4%). Hemorrhagic s...

Obesity Paradox in TAVR: Nationwide Study from 2011-14 Comparing Outcomes of Patients with versus without Obesity Undergoing TAVR
Obesity is associated with several cardiovascular diseases including aortic valve stenosis. Studies have demonstrated a beneficial effect of obesity on patients with cardiovascular disease, deemed the “obesity paradox.” This paradox is also present in obese patients undergoing total aortic valve replacement (TAVR) when examining both short and long-term mortality rates, although the data is conflicting. We aim to investigate the effects of obesity on mortality, length of hospital stay, and ra tes of stroke and cardiogenic shock in patients undergoing TAVR.

Common Postcardiothoracic Surgery Arrhythmias
Cardiac arrhythmias are common after cardiac surgery and have profound sequelae. Bradycardias are typically transient and have reversible causes; however, persistent atrioventricular block is an indicator for permanent pacemaker implantation after valvular surgery. Transcatheter aortic valve surgery is associated with even higher rates of permanent pacemaker implantation. Atrial fibrillation, the most common postoperative arrhythmia, is associated with ischemic stroke, myocardial infarction, congestive heart failure, and short-term mortality. Ventricular arrhythmias have extremely high in-hospital mortality, as well as lon...

Commentary: Atrial fibrillation after aortic valve replacement: Predict, prevent, protect
When atrial fibrillation (AF) occurs after cardiac surgery, surgeons consider the arrhythmia a nuisance rather than a complication. This reflects natural optimism. Although perioperative AF is most often self-limited, it is associated with increased risk of stroke and death, increased hospital length of stay, and increased health care costs.1 Still, we tend not to worry too much because postoperative AF tends to resolve regardless of treatment strategy.1

Left Atrial Thrombus Formation in a Patient With Severe Non-rheumatic Mitral Stenosis After Mitral Valve Repair Receiving Dual Antiplatelet Therapy: A Clinical Challenge
A 60-YEAR-OLD, 88-kg, 165-cm woman presented to a community hospital with heart failure 5 years after mitral valve repair for mitral regurgitation. The patient previously suffered an ischemic stroke and was currently treated with dual antiplatelet therapy. Transesophageal echocardiography revealed severe mitral stenosis with a mean transmitral gradient of 10 mmHg and thickening of the posterior left atrial wall. The patient was then transferred to the authors ’ institution for mitral valve replacement.

Goal-directed therapy during transthoracic oesophageal resection does not improve outcome: Randomised controlled trial
BACKGROUND Goal-directed therapy (GDT) is expected to be of highest benefit in high-risk surgery. Therefore, GDT is recommended during oesophageal resection, which carries a high risk of postoperative complications. OBJECTIVES The aim of this study was to confirm the hypothesis that GDT during oesophageal resection improves outcome compared with standard care. DESIGN A randomised controlled study. SETTING Two Swedish university hospitals, between October 2011 and October 2015. PATIENTS Sixty-four patients scheduled for elective transthoracic oesophageal resection were randomised. Exclusion criteria included c...

Minimally invasive aortic valve replacement through a right anterolateral mini-thoracotomy for the treatment of octogenarians with aortic valve stenosis
AbstractBecause of concerns about the high risk of perioperative complications, the feasibility of minimally invasive aortic valve replacement (MIAVR) for elderly patients remains controversial. Here, we review our results of MIAVR in octogenarians with aortic valve stenosis (AS). Between October 2012 and December 2017, 110 patients with AS underwent MIAVR via a right anterolateral mini-thoracotomy; 41 patients were octogenarian (Group O). The perioperative outcomes of these patients were compared with those of the 69 patients who were less than 80  years of age (Group Y). A preoperative contrast-enhanced computed tomogra...
