Percutaneous Intervention With GuideLiner Catheter in 4 Patients With Anomalous Coronary Artery Originating From Opposite Sinus of Valsalva.

Percutaneous intervention in anomalous coronary arteries originating from the opposite sinus of Valsalva is complicated by their unusual location and course, which makes selective cannulation difficult. The GuideLiner (Vascular Solutions, Inc.) is a monorail guide extension catheter designed to advance beyond the tip of a mother guide catheter to enable deep intubation of a coronary artery, provide extra support, and improve coaxial alignment.

Left Bundle Branch Block after Transcatheter Aortic Valve Implantation with Edwards Sapien 3 Valve: Influence of the Valve Depth Implantation.

Objectives: The aim of this study is to determine the relation between the valve depth implantation and the new-onset left bundle branch block (LBBB) in patients treated with transcatheter aortic valve implantation (TAVI) using Edwards Sapien 3 (S3) prosthesis.

Background: LBBB is the most common conduction disturbance after TAVI. The S3 has been associated with a higher incidence of LBBB.

Placement of a single Axxess stent as new treatment strategy for Medina 1,0,0 left main stem bifurcation lesion.

A left main stem bifurcation lesion (Medina 1,0,0) treated with a single Axxess stent through radial access is presented. Although the use of this stent in left main stenosis is off label, in selected cases it may simplify the technique, avoiding the use of additional overlapping stents and ensuring the bifurcation coverage with minimal amount of metal at the carina.

Coronary lesions quantification with dual-axis rotational coronary angiography.

Background: Coronary angiography (CA) has been the gold standard technique for studying coronary artery disease. It is based on the analysis of bidimensional orthogonal projections that may not be optimal to estimate determinate coronary segments. Rotational angiography "Xperswing" (DARCA) is a new technique that allows the visualization of the coronary arteries from multiple views, with a single contrast injection.

[Myocardial infarction and 5,10-methylenetetrahydro-folate reductase mutation].

A 40-year-old woman with previous venous thrombosis in the lower limbs had recurrent myocardial infarction in the early puerperium. The only documented risk factor was an elevated level of plasma homocysteine, associated to a heterozygotic anomaly in the enzyme responsible for its metabolism, 5,10-methylenetetrahydrofolate reductase. The case and approaches to treatment are discussed.
