This prespecified secondary analysis of the MOMENTUM 3 randomized clinical trial aims to determine whether clinical outcomes of patients with 2 different left ventricular assist devices differed based on preoperative categories of bridge to transplant/bridge to candidacy vs destination therapy.

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.

In this issue of JAMA Cardiology, Lim and colleagues report on cardiovascular functional reserve in people with end-stage renal disease before and after kidney transplant. They performed a 3-arm, prospective, concurrent cohort study to assess change in cardiovascular functional reserve after kidney transplant using state-of-the-art cardiopulmonary exercise testing (CPET). They also assessed left ventricular morphologic findings 1 year after transplant. They enrolled 81 participants with stage 5 chronic kidney disease (CKD) who underwent kidney transplant, 85 wait-listed participants with stage 5 CKD who had not undergone transplant, and 87 controls treated for hypertension only. The authors quantified cardiovascular functional reserve using CPET in parallel with transthoracic echocardiography. One year after transplant, a significant improvement in maximum oxygen consumption was found in the transplant group compared with the nontransplant group. Moreover, left ventricular function improved but not the body mass index.

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 assesses cardiovascular functional reserve before and after kidney transplant in patients with end-stage renal disease.
