ReviewInsights into onco-cardiology: atrial fibrillation in cancer.
Atrial fibrillation (AF) has been found to occur with an increased frequency in patients with malignancies, particularly in those undergoing cancer surgery. The occurrence of AF in cancer may be related to comorbid states or a direct tumor effect or may represent a complication of cancer surgical or medical therapy, whereas inflammation may be a common denominator for both conditions. Treating AF in patients with malignancies is a challenge, especially in terms of antithrombotic therapy, because cancer may result in an increased risk of either thrombosis or hemorrhage and an unpredictable anticoagulation response, whereas thromboembolic risk prediction scores such as CHADS2 (Cardiac Failure, Hypertension, Age, Diabetes, and Stroke [doubled]) may not be applicable. The general lack of evidence imposes an individualized approach to the management of AF in those patients, although some general recommendations based on current guidelines in noncancer patients and the existing evidence in cancer patients, where available, may be outlined.

Randomized Controlled Trial Multicenter StudyST-segment elevation myocardial infarction treated by radial or femoral approach in a multicenter randomized clinical trial: the STEMI-RADIAL trial.
This study sought to compare radial and femoral approaches in patients presenting with ST-segment elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PCI) by high-volume operators experienced in both access sites. ⋯ In patients with STEMI undergoing primary PCI by operators experienced in both access sites, the radial approach was associated with significantly lower incidence of major bleeding and access site complications and superior net clinical benefit. These findings support the use of the radial approach in primary PCI as first choice after proper training. (Trial Comparing Radial and Femoral Approach in Primary Percutaneous Coronary Intervention [PCI] [STEMI-RADIAL]; NCT01136187).

Randomized Controlled Trial Multicenter StudyProcedural volume and outcomes with radial or femoral access for coronary angiography and intervention.
The study sought to evaluate the relationship between procedural volume and outcomes with radial and femoral approach. ⋯ Procedural volume and expertise are important, particularly for radial percutaneous coronary intervention. (A Trial of Trans-radial Versus Trans-femoral Percutaneous Coronary Intervention [PCI] Access Site Approach in Patients With Unstable Angina or Myocardial Infarction Managed With an Invasive Strategy [RIVAL]; NCT01014273).

Multicenter StudyFeasibility and safety of uninterrupted rivaroxaban for periprocedural anticoagulation in patients undergoing radiofrequency ablation for atrial fibrillation: results from a multicenter prospective registry.
The purpose of this study was to evaluate the feasibility and safety of uninterrupted rivaroxaban therapy during atrial fibrillation (AF) ablation. ⋯ Uninterrupted rivaroxaban therapy appears to be as safe and efficacious in preventing bleeding and thromboembolic events in patients undergoing AF ablation as uninterrupted warfarin therapy.
