Patients with severe aortic stenosis (AS) may show left ventricular (LV) apical longitudinal strain sparing. Transcatheter aortic valve implantation (TAVI) improves LV systolic function in patients with severe AS. However, the changes in regional longitudinal strain after TAVI have not been extensively evaluated. This study aimed to characterize the effect of the pressure overload relief after TAVI on LV apical longitudinal strain sparing. A total of 156 patients (mean age 80 ± 7 years, 53% men) with severe AS who underwent computed tomography before and within 1 year after TAVI (mean time to follow-up 50 ± 30 days) were included. LV global and segmental longitudinal strain were assessed using feature tracking computed tomography. LV apical longitudinal strain sparing was evaluated as the ratio between the apical and midbasal longitudinal strain and was defined as an LV apical to midbasal longitudinal strain ratio >1. LV apical longitudinal strain remained stable after TAVI (from 19.5 ± 7.2% to 18.7 ± 7.7%, p = 0.20), whereas LV midbasal longitudinal strain showed a significant increase (from 12.9 ± 4.2% to 14.2 ± 4.0%, p ≤0.001). Before TAVI, 88% of the patients presented with LV apical strain ratio >1% and 19% presented with an LV apical strain ratio >2. After TAVI, these percentages significantly decreased to 77% and 5% (p = 0.009, p ≤0.001), respectively. In conclusion, LV apical sparing of strain is a relatively common finding in patients with severe AS who underwent TAVI and its prevalence decreases after the afterload relief after TAVI.

Background: Despite a phenylalanine (Phe) restrictive diet, most adult patients with 'classical' phenylketonuria (PKU) maintain life-long Phe concentrations above the normal range and receive tyrosine (Tyr) and protein-enriched diets to maintain acceptable concentrations and ensure normal development. While these interventions are highly successful in preventing adverse neuropsychiatric complications, their long- term consequences are incompletely explored. We observed early cardiomyopathic characteristics and associated hemodynamic changes in adult PKU patients and present here the results of a longitudinal evaluation of cardiac phenotype.

Objective: Although left ventricular hypertrophy frequently accompanies end-stage renal disease, heart failure (HF) with reduced ejection fraction (EF) is also observed in a subset of patients. In those patients kidney transplantation (KT) is generally avoided due to an increased risk of mortality in addition to the risks associated with HF. This prospective study was designed to follow patients with HF who were being prepared for KT.

Background: Cardiovascular disease (CVD) remains the leading cause of death in pregnant and peripartal women in western countries. Physiological changes during pregnancy can lead to cardiovascular complications in the mother; women with pre-existing heart disease may not tolerate these changes well, increasing their susceptibility to adverse cardiovascular outcomes during pregnancy. The aim of this study is to characterize pregnancy-induced changes in cardiac function, biomarker concentrations and cardiovascular outcomes in women with CVD during pregnancy at a tertiary care hospital in Germany.

Background: Dextro-transposition of the great arteries (dTGA) stands out as a prevalent cyanotic congenital heart defect (CHD), characterized by an intricate reversal in the arrangement of the major arteries. In the past, several surgical procedures have been used to treat dTGA, including the atrial switch. Although the method is no longer used, survivors of the procedure still living among us.

Objectives: To investigate the predictive value of myocardial strain for cardiotoxicity associated with fluorouracil-based chemotherapies in gastrointestinal cancer patients.
Methods: Patients with diagnosis of gastrointestinal cancers, who were hospitalized for chemotherapy involving antimetabolic drugs, were eligible in this prospective study. Echocardiography was performed before and after each chemotherapy cycle during hospitalization until the completion of chemotherapy.
