Transcatheter edge-to-edge repair following surgical valve repair with ring implantation: Results from the multicentre "Clip-in-Ring" registry.

Background: Management of mitral regurgitation recurrence after failed surgical valve repair with ring implantation is controversial.

Aim: To describe the French experience regarding midterm safety and efficacy of transcatheter edge-to-edge mitral valve repair (TEER) in patients with failed surgical valve repair with ring implantation.

Methods: The "Clip-in-Ring" registry is a multicentre registry conducted in 11 centres in France, approved by local institutional review boards, of consecutive TEER following surgical valve repair with ring implantation.

Effectiveness and Safety of P2Y12 Inhibitors Pretreatment in Primary Percutaneous Coronary Intervention with Long Transfer Times.

Background: Early initiation of a new P2Y12 inhibitor in ST-elevation myocardial infarction (STEMI) patients prior to primary percutaneous coronary intervention (PCI) is recommended over clopidogrel. However, comparative data remain limited, especially in semi-rural regions with subsequent longer transfer times.

Objectives: We aimed to assess the determinants, effectiveness, and safety of pretreatment with new P2Y12 inhibitors compared with clopidogrel in a primary PCI regional network.

EFFICACY OF AN ADDITIONAL MOBILE LEADED SHIELD ON OPERATOR RADIATION DURING PERCUTANEOUS CORONARY ANGIOGRAPHY.

Operator radiation protection during percutaneous coronary angiography (CA) is a growing concern in the catheterisation laboratory (cath lab). The purpose of this study was to evaluate the efficacy of an additional mobile leaded shield on operator radiation exposure during diagnostic CA. The study involved two operators from the same cath lab and patients scheduled for diagnostic coronary catheterisation over a period of 2 months.

Clinical and electrocardiographic predictors of a positive response to cardiac resynchronization therapy in advanced heart failure.

Aims: Cardiac resynchronization therapy (CRT) is an effective treatment for refractory congestive heart failure (CHF). However, up to 30% of patients do not respond to CRT. The aim of this study was to identify clinical and electrocardiographic (ECG) predictors of a positive response to CRT.

Inflow effect in first-pass cardiac and renal MRI.

Purpose: To estimate the effect of the inflow effect on the arterial input function in vivo in cardiac and renal MR perfusion imaging using fast gradient echo (GRE) sequences and contrast media.

Materials And Methods: The MR exam protocol was designed to acquire images at different phases of the cardiac cycle. The arterial input was thus influenced by various blood flow velocities.
