Cardiovascular disease is a significant cause of morbidity and mortality in patients with end-stage renal disease (ESRD) and kidney transplant (KT) patients. Compared with left ventricular (LV) ejection fraction (LVEF), LV strain has emerged as an important marker of LV function as it is less load dependent. We sought to evaluate changes in LV strain using cardiovascular magnetic resonance imaging (CMR) in ESRD patients who received KT, to determine whether KT may improve LV function. We conducted a prospective multi-centre longitudinal study of 79 ESRD patients (40 on dialysis, 39 underwent KT). CMR was performed at baseline and at 12 months after KT. Among 79 participants (mean age 55 years; 30% women), KT patients had significant improvement in global circumferential strain (GCS) (p = 0.007) and global radial strain (GRS) (p = 0.003), but a decline in global longitudinal strain (GLS) over 12 months (p = 0.026), while no significant change in any LV strain was observed in the ongoing dialysis group. For KT patients, the improvement in LV strain paralleled improvement in LVEF (57.4 ± 6.4% at baseline, 60.6% ± 6.9% at 12 months; p = 0.001). For entire cohort, over 12 months, change in LVEF was significantly correlated with change in GCS (Spearman’s r = − 0.42, p < 0.001), GRS (Spearman’s r = 0.64, p < 0.001), and GLS (Spearman’s r = − 0.34, p = 0.002). Improvements in GCS and GRS over 12 months were significantly correlated with reductions in LV end-diastolic volume index and LV end-systolic volume index (all p < 0.05), but not with change in blood pressure (all p > 0.10). Compared with continuation of dialysis, KT was associated with significant improvements in LV strain metrics of GCS and GRS after 12 months, which did not correlate with blood pressure change. This supports the notion that KT has favorable effects on LV function beyond volume and blood pessure control. Larger studies with longer follow-up are needed to confirm these findings.

The Ross procedure is gaining recognition as a significant option for aortic valve replacement (AVR), and is particularly beneficial in specific patient groups. Although categorized as a class IIb recommendation in the 2020 American College of Cardiology (ACC)/American Heart Association (AHA), and the European Society of Cardiology (ESC) management guidelines on valvular heart disease, recent studies bolster its credibility. Research, including a propensity-matched study, underlines the Ross procedure’s association with enhanced long-term survival and reduced adverse valve-related events compared to other AVR types. This positions the Ross procedure as a primary option for AVR in young and middle-aged adults within specialized centers, and potentially the only choice for children and infants requiring AVR. This review meticulously examines the Ross procedure, covering historical perspectives, surgical techniques, imaging, and outcomes, including hemodynamic performance and quality of life, especially focusing on pediatric and young adult patients. It explores contemporary techniques and innovations like minimally invasive approaches and tissue engineering, underscoring ongoing research and future directions. A summarization of comparative studies and meta-analyses reiterates the Ross procedure’s superior long-term outcomes, valve durability, and preservation of the left ventricular function, accentuating the crucial role of patient selection and risk stratification, and pinpointing areas for future research.

Heart failure (HF) remains a critical global health challenge, necessitating advancements in diagnostic and therapeutic strategies. This review explores the evolution of imaging technologies and their impact on HF management, focusing on three-dimensional echocardiography (3DE), myocardial strain imaging, and vortex dynamics imaging. Three-dimensional echocardiography enhances traditional echocardiography by providing more accurate assessments of cardiac structures, while myocardial strain imaging offers the early detection of subclinical myocardial dysfunction, crucial in conditions such as chemotherapy-induced cardiotoxicity and ischemic heart disease. Vortex dynamics imaging, a novel technique, provides insights into intracardiac flow patterns, aiding in the evaluation of left ventricular function, valve diseases, and congenital heart anomalies. The integration of these advanced imaging modalities into clinical practice facilitates personalized treatment strategies, enabling the earlier diagnosis and more precise monitoring of disease progression. The ongoing refinement of these imaging techniques holds promise for improving patient outcomes and advancing the field of precision medicine in HF care.

Pharmacogenomic (PGx) testing has proven significant clinical utility in minimizing adverse drug reactions and maximizing therapeutic effects. This report is a proof of concept of the clinical implementation of PGx testing at a tertiary care hospital in Riyadh, Saudi Arabia. In collaboration with different departments, we implemented the PGx testing clinical service into our electronic health record cerner for heart and neurology centers patients. We used the PharmacoScan microarray-based test to perform genotyping. To date, 512 patients have been tested. 97.5% of all patients have at least 1 gene with altered function. Among those patients, n = 402 (78.5%) had 3 or more genes with altered function (3 genes = 197, 38.5%, 4 genes = 134, 26.2%, 5 genes = 58, 11.3%, and 6 genes = 13, 2.5%). Our work describes the successful implementation of PGx testing in clinical practice and encourages further research on improving patient outcomes. Moreover, we describe the major challenges at each step of our approach, which provides our institute and others with lessons and insights on implementing PGx testing into clinical practice.

Nowadays, the diagnosis of cardiac myxomas (CM), particularly the histological types, remains a challenge. Two-dimensional (2D) transthoracic (TT) and transesophageal (TEE) echocardiography (ECHO) represent the first steps in the imaging pathway. 3D ECHO, implemented in imaging practice, appears to be an emerging diagnostic technique that overcomes some of the limitations of 2D ECHO while integrating the information provided by magnetic resonance (MRI). However, its role in the imaging arena is still debatable. Analyzing 17 myxomas in 13 patients, the study uncovers a diverse anatomical spectrum. Classical CM morphology is a minority, with most myxomas being sessile and originating from unexpected locations (right ventricular outflow tract and left atrial appendage). Texture and size variations are also noted. Comparing imaging, 2D TEE outperforms 2D TT in visualizing anatomical features, especially attachment types. 3D TEE confirms 2D TT findings and offers more detailed assessments, identifying peduncles missed in four cases by 2D TEE. Two small recurrent myxomas were exclusively detected by 3D TEE, not by 2D TEE or MRI. Two patients have papillary myxomas, one has an embolism. Another patient with a solid myxoma also suffers an embolism, with a clot found at the apex during surgery. Our study showed that CM has a wide anatomical spectrum beyond the typical features, making the diagnosis challenging. Therefore, a multimodality imaging approach is essential for distinguishing CM from other cardiac masses and differentiating myxoma histological types. These findings stress the importance of incorporating 3D ECHO alongside other imaging techniques for a comprehensive evaluation.
