Hypoplastic right ventricle is a rare congenital disease usually associated with pulmonary atresia or tricuspid atresia. Isolated right ventricular hypoplasia is a rare anomaly without important valvular abnormalities. It is associated with inter atrial septal defects leading to the right-to-left shunting of blood. Patients with isolated right ventricular hypoplasia usually have different and variable courses. In some patients, it is recognized in the perinatal period and necessitates prompt intervention; nonetheless, there are some reports of this anomaly in old age with no significant symptoms. In this report, we describe the clinical data and management of 6 adult cases with isolated right ventricular hypoplasia treated medically or surgically based on the severity of the disease and symptoms and then offer an in-depth discussion regarding this rare anomaly.

“…Resting conventional 2D transthoracic echocardiography was performed using a GE Vivid E95 (GE Vingmed, Horten, Norway). Measurements of RV systolic function, including TAPSE, RV-S′, and RV-FAC were obtained according to consensus guidelines [11,12,13].…”

Diabetes mellitus is a risk factor for adverse cardiovascular events, and it can raise the risk of heart failure. The right ventricle makes an important contribution to overall cardiac function, and right ventricular(RV) dysfunction will affect the course and outcome of the disease, therefore, early identification of right ventricular myocardial systolic dysfunction is of great clinical importance. We sought to apply two-dimensional speckle-tracking echocardiography (2D-STE) techniques to determine whether right ventricular global longitudinal strain (RVGLS) and right ventricular free wall strain (RV-FWLS) are altered in patients with prediabetes and diabetes mellitus.This cross-sectional study included 43 patients with prediabetes,52 patients with type 2 diabetes mellitus(T2DM), and 49 age- and sex-matched healthy volunteers were included as controls. Conventional echocardiography measured tricuspid annular systolic excursion (TAPSE), tricuspid valve systolic velocity (RV-S'), and right ventricular fractional change (RV-FAC), and 2D-STE measured left ventricular longitudinal strain (LVGLS), RVGLS, and RV-FWLS. The results showed that TAPSE was not significantly different between the prediabetes group and the control and diabetic groups and RV-S' velocity was not significantly different among the three groups. RV-FAC showed no statistically significant difference between the prediabetes and diabetic groups, RVGLS were significantly impaired and significantly different in the three groups (P=0.000).RVGLS modestly correlated with glycosylated hemoglobin A1c(HbA1c)(r=﹣0.576,P=0.000), and weakly with RVFAC(r=0.398,P=0.000), LVGLS(r=0.416,P=0.000), sex(r=﹣0.205,P=0.014),BMI(r=﹣0.195,P=0.019),heart rate(r=﹣0.216,P=0.009),Triglycerides(r=﹣0.198,P=0.025),interventricular septal thickness(r=﹣0.208,P=0.012),LV end-diastolic diameter(r=0.210,P=0.012),septum strain(r=0.438,P=0.000). Further regression analysis we found that HbA1c(B=﹣0.440,P= .000), septum strain (B=0.301, P=0.000),LV end-diastolic diameter (B=0.226, P=0.001), sex(B=﹣0.134, P=.043) were independently associated with RVGLS in the whole study population.RVGLS was the best diagnostic indicator for prediabetes and diabetes (AUC values of 0.689 and 0.731, respectively), and a cut-off value of RVGLS ≤18.95% had 85% sensitivity and 61% specificity for the diagnosis of prediabetes and ≤17.55% had 82% sensitivity and 58% specificity for the diagnosis of diabetes. Therefore, we believe that abnormally elevated hyperglycemia negatively affects the myocardial function of the right ventricle, The decrease of right ventricular systolic function may be related to left ventricular remodeling and myocardial strain. two-dimensional speckle tracking echocardiography can detect subtle changes in impaired right ventricular systolic function. HbA1c, septum strain, LV end-diastolic diameter, the sex were independent risk factors for RVGLS.

“…Patients with TR were identified using the University of Utah medical records database and a combination of procedure and diagnosis codes. Patient imaging data was analyzed from short axis CINE-MRI images, which were acquired as part of routine clinical care [12,13]. All participants and use of clinical data were approved by the University of Utah Internal Review Board.…”

Tricuspid regurgitation (TR) is a failure in right-sided AV valve function which, if left untreated, leads to marked cardiac shape changes and heart failure. However, the specific right ventricular shape changes resulting from TR are unknown. The goal of this study is to characterize the RV shape changes of patients with severe TR. RVs were segmented from CINE MRI images. Using particlebased shape modeling (PSM), a dense set of homologous landmarks were placed with geometric consistency on the endocardial surface of each RV, via an entropybased optimization of the information content of the shape model. Principal component analysis (PCA) identified the significant modes of shape variation across the population. These modes were used to create a patient-prediction model. 32 patients and 6 healthy controls were studied. The mean RV shape of TR patients demonstrated increased sphericity relative to controls, with the three most dominant modes of variation showing significant widening of the short axis of the heart, narrowing of the base at the RV outflow tract (RVOT), and blunting of the RV apex. By PCA, shape changes based on the first three modes of variation correctly identified patient vs. control hearts 86.5% of the time. The shape variation may further illuminate the mechanics of TR-induced RV failure and recovery, providing potential targets for therapies including novel devices and surgical interventions.
