[Temporary percutaneous ventricular assist devices for cardiogenic shock and high-risk percutaneous coronary intervention: a systematic literature review].

Background: Percutaneous ventricular assist devices (pVADs) are frequently used for the treatment of patients with cardiogenic shock (CS) due to acute myocardial infarction (AMI) and as a support in percutaneous coronary intervention (PCI) for high-risk patients. CS is a clinical condition characterized by inadequate tissue perfusion due to cardiac dysfunction and for 80% of cases it is caused by AMI with left ventricular insufficiency. CS is responsible for about 50% of deaths in patients with myocardial infarction.

Comparison of cryoballoon and radiofrequency ablation techniques for atrial fibrillation: a meta-analysis.

Aims: To perform an updated meta-analysis to assess efficacy, safety and technical performance of pulmonary vein isolation using cryoballoon or radiofrequency catheter ablation in patients with paroxysmal or persistent atrial fibrillation.

Methods: In June 2017, databases and websites were systematically searched for systematic reviews, randomized controlled trials and observational studies reporting data on efficacy, safety and technical performance outcomes at follow-up at least 12 months. Researchers independently assessed records' eligibility, inclusion and methodological quality of included studies.

Informative value of clinical research on multislice computed tomography in the diagnosis of coronary artery disease: A systematic review.

Unlabelled: Multislice Spiral Computed Tomography (MSCT) is an emerging non-invasive diagnostic modality to detect coronary artery disease, which may alter diagnostic pathways and change the current clinical role of conventional coronary angiography.

Aims: To retrieve and critically assess information from the available literature on MSCT (>/=16-slice) concerning its diagnostic accuracy, safety, applicability, clinical impact and cost-effectiveness.

Methods And Results: Articles published between January 2002 and March 2007 were identified through searches of the Cochrane Library, MEDLINE, and other websites of manufacturers, cardiac professional societies, guidelines and abstracts from conference meetings.
