Journal Articles: Pulmonary vein isolation (PVI) is an effective strategy for patients with paroxysmal atrial fibrillation (AF).1 However, in patients with persistent AF and long-standing persistent AF, PVI is associated with limited success, with patients not responding to PVI.2 Recently, the BELIEF trial (Effect of Empirical Left Atrial Appendage Isolation on Long-term Procedure Outcome in Patients With Persistent or Longstanding Persistent Atrial Fibrillation Undergoing Catheter Ablation) showed that an electric isolation of the left atrial (LA) appendage (LAA) in addition to PVI could increase clinical success.3 Although potentially effective, this strategy causes electromechanical dissociation of the LAA and was assumed to be associated with increased risk for LAA thrombus and thromboembolism.4 We sought to investigate the incidence of LAA thrombus and thromboembolism and the impact of LAA closure on the prevention of thromboembolic events, in addition to the clinical benefit after left atrial appendage isolation (LAAI).

European Heart Rhythm Association (EHRA)/Heart Rhythm Society (HRS)/ Asia Pacific Heart Rhythm Society (APHRS)/Latin American Heart Rhythm Society (LAHRS) expert consensus statement on catheter and surgical ablation of atrial fibrillation
Catheter ablation of atrial fibrillation is an important treatment option for maintaining a normal heart rhythm and reducing arrhythmia-related symptoms. This consensus statement provides healthcare providers with clinical practice standards and advice on which patients should receive ablation, how to perform the procedure, and how to manage patients before, during, and afterwards.
2012 American College of Cardiology Foundation/Society for Cardiovascular Angiography and Interventions Expert Consensus Document on Cardiac Catheterization Laboratory Standards Update: A Report of the American College of Cardiology Foundation Task Force
Journal Articles: The last expert consensus document on cardiac catheterization laboratory standards was published in 2001 (1). Since then, many changes have occurred as the setting has evolved from being primarily diagnostic based into a therapeutic environment. Technology has changed both the imaging and reporting systems. The lower risk of invasive procedures has seen the expansion of cardiac catheterization laboratories to sites without onsite cardiovascular surgery backup and even to community hospitals where primary percutaneous coronary intervention (PCI) is now being performed. This has increased the importance of quality assurance (QA) and quality improvement (QI) initiatives. At the same time, the laboratory has become a multipurpose suite with both diagnostic procedures to investigate pulmonary hypertension and coronary flow and with therapeutic procedures that now include intervention into the cerebral and peripheral vascular systems as well as in structural heart disease. These new procedures have impacted both the adult and pediatric catheterization laboratories. The approaches now available allow for the treatment of even very complex heart disease and have led to the development of hybrid cardiac catheterization laboratories where a team of physicians (including invasive cardiologists, cardiovascular surgeons, noninvasive cardiologists, and anesthesiologists) is required.
