Article Synopsis
- The study investigates the connection between aortic valve calcification (AVC) and the severity of low-gradient aortic stenosis (AS) in patients with specific criteria for aortic valve area and peak velocity.
- A total of 214 patients underwent dobutamine stress echocardiography (DSE) and multislice computed tomography; results showed poor sensitivity and specificity of AVC for determining AS severity.
- The findings suggest AVC scores are not reliable enough to substitute for DSE in diagnosing low-gradient severe AS in patients.
Contrast exposure during left atrial appendage occlusion may be harmful in those with chronic kidney disease or allergy. This single-center registry (n = 31) demonstrates the feasibility and safety of zero-contrast percutaneous left atrial appendage occlusion using echocardiography, fluoroscopy, and fusion imaging, with 100% procedural success and no device complications at 45 days.

- Current transcatheter therapies for tricuspid valve replacement differ in design, fixation, and anchoring methods.!* -
- The report discusses the use of the Intrepid device, which replaces the tricuspid valve by anchoring it through oversizing at the annular perimeter.!* -
- This case specifically addresses severe tricuspid regurgitation caused by leaflet interference from a ventricular septal defect occluder.!*
New therapeutic approach for tricuspid regurgitation: Transcatheter tricuspid valve replacement or repair.

The tricuspid valve is a complex structure with normal function dependent on the leaflet morphology, right atrial and annular dynamics, and right ventricular and chordal support. Thus, the pathophysiology of tricuspid regurgitation (TR) is equally complex and current medical and surgical management options are limited. Transcatheter devices are currently being investigated as possible treatment options with lower morbidity and mortality than open surgical procedures.

Newer 3-dimensional ICE catheters have enhanced imaging and real-time functionality. We present a novel case of mitral valve transcatheter edge-to-edge repair where transesophageal imaging was limited by massive hiatal hernia and where complementary 3D ICE imaging enabled procedural success.

Methods: Clinical and genetic data of 44 probands referred to a cardiac genetics clinic (2007-2017) who met 2010 Task Force Criteria (TFC) for ARVC diagnosis were included.
Results: Thirty-three (33) (75%) male, 20 (45%) were referred by the Victorian Institute of Forensic Medicine.
Aim: A systematic review and meta-analysis, evaluating ischemic conditioning during percutaneous coronary intervention (PCI).
Methods & Results: A database search of randomized trials of ischemic conditioning in PCI created three subgroups for meta-analysis: mortality in elective PCI with remote ischemic preconditioning (RIPreC; subgroup 1a, n = 3) - no outcome difference between RIPreC and control (odds ratio: 0.34; 95% CI: 0.
