Multicenter StudyA propensity-score matched analysis on the impact of postoperative atrial fibrillation on the early and late outcomes after concomitant aortic valve replacement and coronary artery bypass graft surgery.
Postoperative atrial fibrillation (POAF) is a known complication of cardiac surgery. There is a paucity of data on the effects of POAF on short-term and long-term outcomes after concomitant aortic valve replacement and coronary artery bypass grafting (AVR-CABG ). ⋯ POAF was not associated with an increased risk of early or late mortality. It is, however, associated with poorer perioperative outcomes. It is important to evaluate potential treatment strategies for POAF.

Prevalence of stroke and the need for thromboprophylaxis in young patients with atrial fibrillation: a cohort study.
Atrial fibrillation is the most common cardiac arrhythmia, and age is a well-established independent risk factor for stroke in these patients. Whereas high-risk patients clearly benefit from anticoagulation to prevent stroke, less is known about how to treat low-risk patients. Despite the recent guidelines and studies demonstrating no benefit and excess bleeding risk with aspirin, many low-risk patients still receive this medication. ⋯ There was one event identified, a transient ischemic attack in a man not on aspirin with CHADS2 and CHADS2-VASc scores of 1, resulting in event rates of 0.234 per 100 patient-years overall or 0.392 among those not on aspirin. Patients with nonvalvular atrial fibrillation under age 35 have an exceedingly low stroke risk. We assert that aspirin may be unnecessary for most patients in this population, especially those with a CHA2DS2-VASc score of 0.

Minimally invasive aortic valve replacement with Perceval valves: first clinical experience.
Although minimally invasive aortic valve replacement (MIAVR) has been shown to cause less morbidity than conventional surgery, it has not yet received broad application. The purpose of this study was to evaluate sutureless implantation using the Perceval S aortic valve bioprosthesis (Sorin Group, Saluggia, Italy) via ministernotomy. ⋯ This study shows that sutureless implantation of the Perceval S aortic valve bioprosthesis provides a simple and reproducible alternative for MIAVR. As the valve does not need to be sutured, it may also result in reduced ACC and CPB times. This self-anchoring valve may also allow the application of MIAVR to a broader spectrum of patients. This new technology needs a long-term follow-up.

Review Meta AnalysisB-type natriuretic peptide-guided versus symptom-guided therapy in outpatients with chronic heart failure: a systematic review with meta-analysis.
It has been asserted that serial measurements of natriuretic peptides, specifically B-type natriuretic peptide (BNP) or the amino-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP), may serve as an objective practical guide to better tailor the drug treatment for patients with chronic heart failure (CHF), and especially to detect the cases of subclinical congestion that would require an increase in drug dosing. However, considerable uncertainty remains about the alleged useful role of natriuretic peptide-guided therapy in this context. Therefore, we decided to execute a meta-analysis of published randomized controlled trials (RCTs) to test the hypothesis that an improvement of clinical outcomes in outpatients with CHF may be achieved by adjustment of pharmacologic dosing performed according to natriuretic peptide determinations. ⋯ This meta-analysis supports the hypothesis that natriuretic peptide-guided therapy is superior to symptom-guided therapy for improving clinical outcomes in CHF outpatients. However, some large RCTs failed to document significant clinical improvement in terms of mortality and morbidity using a natriuretic peptide-guided strategy; thus, any attempt to clarify this still unresolved issue by means of further basic and clinical research is recommended in the future.

Multicenter StudyRole of hypertension on new onset congestive heart failure in patients receiving trastuzumab therapy for breast cancer.
Adjuvant trastuzumab therapy improves survival of Human Epidermal growth factor receptor 2 (HER2)-positive women with early breast cancer (EBC). Trastuzumab-induced cardiotoxicity is not uncommon. In the setting of community patients, the incidence, timing and phenotype of new onset congestive heart failure (CHF) is unknown. ⋯ New onset CHF occurs seldom in HER2-positive women with EBC, prevalently in the first 6 months of therapy. CHF is associated with a significant reduction in LVEF and is predicted by a history of hypertension.
