This study develops and validates a quantitative method to predict the pulmonary to systemic flow ratio in patients with congenital heart disease from chest radiographs using deep learning.

This cohort study assesses whether long-term variability and rate of change of blood pressure from young adulthood to midlife are associated with cardiovascular disease and all-cause mortality by middle age.

This study developed and validated a prognostic prediction model for patients with heart failure.

To the Editor We read the recent article by Klauser et al with great interest. While the potential implications of the findings are exciting, we have several concerns. First, the authors do not explicitly state whether electrocardiogram gating was used in their study. This is an important detail because cardiac motion artifact is a source of artifactual coloration with dual-energy computed tomography (DECT), particularly with dual-source scanners given the approximately 80-millisecond temporal difference between the 2 radiography beams. Furthermore, beam hardening artifact from calcified atheromas and partial volume effect, known sources of artifacts in the 2-material decomposition algorithm of DECT, may largely explain the findings. While patients with gout had higher prevalence of coronary calcification (55 of 59 patients [93%]) and cardiovascular monosodium urate (MSU) deposition (51 of 59 patients [86%]) than controls, the authors do not report whether the 4 patients with gout without coronary calcifications exhibited MSU deposition nor the number of controls or cadaveric hearts with coronary calcification. The images from the article show areas of green pixelization occurring adjacent to calcified plaques on grayscale computed tomography images (eg, Figure 2A and D, left anterior descending artery [yellow arrowhead]), which would favor this artifact hypothesis without additional data.

In Reply We appreciate the valuable comments of Becce et al on our article. We applied prospective electrocardiography gating using a thin-slice cardiac protocol to ensure highest spatial resolution with minimal motion artifact. A noncontrast electrocardiography-gated computed tomography (CT) examination with standardized scan parameters was performed using a 128-slice dual-source CT (SOMATOM Definition Flash; Siemens) with a detector collimation of 2 × 64 × 0.6 mm, rotation time of 0.28 seconds, and prospective electrocardiography triggering for heart rates less than 65 beats per minute (diastolic padding, 70% of RR interval) and more than 65 beats per minute (systolic padding, 40% of RR interval). Axial images were reconstructed with 0.75-mm slice width, increment of 0.5, and a medium-smooth convolution kernel (B26f). When motion artifact was present, it was distinguished by visual analysis of an experienced observer and colorized pixels related to motion were excluded.

This cohort study uses the UK Biobank cohort data to compare the association of monogenic vs polygenic hypercholesterolemia with the risk of atherosclerotic cardiovascular disease among individuals with comparable levels of low-density lipoprotein cholesterol.

This randomized clinical trial assesses the effectiveness of an implantable loop recorder plus 24-hour Holter electrocardiographic monitoring vs standard 24-hour Holter electrocardiographic monitoring alone for detecting arrhythmias in pregnant women with structural heart disease and/or symptoms suggestive of arrhythmias.

Movie stars in 2014's polls are a welcome addition to the fray. For those carping about how stars represent glamour and gloss, why not?

Lacking a cohesive national campaign, Kejriwal has yet again taken recourse to insurgent tactics – projecting himself as Modi’s only rival when Congress is yet to declare its nominee for Varanasi.

Trinamool Congress appears ready to move forward from the ferocious acrimony of Mamata-Modi exchanges during the election campaign.
