Real-time cardiovascular magnetic resonance-guided radiofrequency ablation: A comprehensive review.

Cardiac magnetic resonance (CMR) imaging could enable major advantages when guiding in real-time cardiac electrophysiology procedures offering high-resolution anatomy, arrhythmia substrate, and ablation lesion visualization in the absence of ionizing radiation. Over the last decade, technologies and platforms for performing electrophysiology procedures in a CMR environment have been developed. However, performing procedures outside the conventional fluoroscopic laboratory posed technical, practical and safety concerns.

A patient with ventricular tachycardia due to a novel mutation of the lamin A/C gene: case presentation and mini review.

Lamin A/C is a major constituent of the nuclear lamina, the proteinaceous meshwork underlying the inner nuclear membrane. Laminopathies are a group of diseases with heterogeneous clinical presentation. Lamin A/C mutations are a well-established cause of dilated cardiomyopathy.

Differential vasoactive response to endothelin receptor antagonists and prostacyclin in patients with severe pulmonary hypertension.

Pulmonary hypertension (PH) is a rare disease of the pulmonary vasculature with diverse pathogenetic mechanisms. Vasoactive substances such as endothelin A receptor (ET(A)) antagonists and prostanoids have been used to improve haemodynamics and clinical outcome. We compared the hemodynamic response to BQ-123 (an ET(A) receptor antagonist) and prostacyclin or its analogue iloprost in ten patients (four men) with a mean age of 35.
