Volumetric cine CMR to quantify atrial structure and function in patients with atrial dysrhythmias.

Purpose: To implement a cardiac magnetic resonance (CMR)-based protocol to define atrial structure and function in individuals with paroxysmal atrial fibrillation (PAF), heritable cardiac conduction and myocardial disease with atrial dysrhtyhmias (HCCMD), and healthy controls.

Methods: Fifteen controls, 20 PAF, and 12 HCCMD subjects underwent CMR examination including: multislice short-axis cine, multislice horizontal long-axis cine, and gadolinium-enhanced coronal plane magnetic resonance angiography (MRA) for pulmonary vein analysis. We also assessed for ventricular myopathy with delayed myocardial enhancement (DME) acquisitions.

Rotational X-ray coronary angiography.

We designed and implemented a digital flat-panel-based rotational X-ray coronary angiography technique hypothesizing that luminal disease could be identified with less radiation exposure and contrast usage compared to conventional angiography. Individuals scheduled for diagnostic coronary angiography were prospectively enrolled. In addition to conventional acquisitions in standard planes, subjects underwent one additional left coronary artery (LCA) or right coronary artery (RCA) rotational (spin) acquisition using a predefined trajectory.

NAMS releases position statement on the treatment of vasomotor symptoms associated with menopause.

The NAMS recommends first considering lifestyle changes, alone or combined with a nonprescription remedy (such as dietary isoflavones, vitamin E, or black cohosh) for the relief of mild vasomotor symptoms. For moderate to severe menopause-related hot flashes, prescription systemic estrogen-containing products are still the therapeutic standard. For women with concerns or contraindications to estrogen-containing products, possible treatment options include prescription progestogens, venlafaxine, paroxetine, fluoxetine, or gabapentin.
