Clinical features, haemodynamics, and outcomes of heart failure with preserved ejection fraction in coarctation of aorta.

Aims: There are similarities in the pathogenesis of cardiac remodelling and dysfunction in heart failure with preserved ejection fraction (HFpEF) and coarctation of aorta (COA). We hypothesized that clinical HFpEF would be highly prevalent in adults with COA, and that the presence of HFpEF would increase the risk of mortality in this population. The aim of this study was to define the clinical features, haemodynamics, and prognostic implications of HFpEF in COA.

Differences in Right Heart Function After Pulmonary Valve Replacement in Patients With Pulmonary Valve Stenosis Versus Tetralogy of Fallot.

Background: There are limited data about the impact of timing of pulmonary valve replacement (PVR) on right heart reverse remodeling in patients with pulmonary regurgitation following intervention for isolated pulmonary valve stenosis (PS). This study compared differences in postprocedural right heart reverse remodeling after early versus late PVR (defined as PVR before versus after attainment of the conservative consensus criteria proposed by Bokma et al, 2018) in patients with prior intervention for PS, using patients with tetralogy of Fallot as the reference group.

Method And Results: Right atrial reservoir strain and right ventricular free wall strain was measured at baseline, 1 and 3 years after PVR.

Impacts of preoperative anxiety and depression on pain and range of motion after arthroscopic frozen shoulder release: a cohort study.

Purpose: We aimed to evaluate the impact of preoperative anxiety and depression levels on baseline and postoperative pain in patients who underwent arthroscopic frozen shoulder release.

Methods: The study included 59 patients with more than three months of idiopathic frozen shoulder. All patients had arthroscopic frozen shoulder release.

Prognostic Role of Tricuspid Annular Plane Systolic Excursion/Right Ventricular Systolic Pressure Ratio in Coarctation of Aorta.

Background: Right ventricular (RV) systolic dysfunction and pulmonary hypertension are associated with mortality in adults with coarctation of aorta (COA). The tricuspid annular plane systolic excursion/RV systolic pressure (TAPSE/RVSP) ratio is a validated noninvasive tool for the assessment of RV-pulmonary arterial (RV-PA) coupling in patients with PA hypertension, but similar data are lacking in adults with COA. The purpose of this study was to assess the relationship between the TAPSE/RVSP ratio and outcomes in this population.

Prognostic role of inferior vena collapsibility index in congenital heart disease: A validation study.

Background: A recent study showed that inferior vena cava collapsibility index (IVCCI) <60% had better prognostic performance as compared to the American Society of Echocardiogram (ASE) criteria for estimating right atrial pressure (RAP). However, this study was based on a selected cohort of adults with congenital heart disease (CHD) that underwent right heart catheterization and limiting the generalizability of the results. The purpose of this study was, therefore, to validate the prognostic performance of IVCCI in a more representative sample of adults with CHD, which would in turn, improve generalizability of the results.

Augmentation plate without bone graft in the management of distal tibial diaphyseal non-union.

Purpose: The objective of this study was to assess the efficacy of augmentation plating with retaining of previous implant in situ in cases of non-united oligotrophic or atrophic aseptic distal tibial diaphyseal and metaphyseal fractures without bone grafting depending on the unified bone healing and non-union theory.

Methods: Through the period between December 2019 and December 2022, twelve patients with distal third tibial non-unions who were fixed at time of fracture either by intramedullary interlocking nails (seven cases) or by minimally invasive plate osteosynthesis (five cases) were included. Non-union was diagnosed on basis of absence of any healing progression in three months period or absence of fracture healing after six months from index surgery.

Determinants and prognostic implications of left atrial reverse remodelling after coarctation of aorta repair in adults.

Aims: Left atrial (LA) dysfunction and atrial fibrillation are also relatively common in adults with coarctation of aorta (COA), and the severity of LA dysfunction is associated with a higher risk of atrial fibrillation in this population. The purpose of this study was to determine whether LA function improved after COA repair (LA reverse remodelling), and the relationship between LA reverse remodelling and atrial fibrillation.

Methods And Results: Retrospective cohort study of adults undergoing COA repair (2003-20).

Prognostic Performance of Right Ventricular Global Longitudinal Strain Measurements in Patients With Ebstein Anomaly.

Background: There are limited data on the prognostic role of right ventricular global longitudinal strain (RVGLS) in patients with Ebstein anomaly.

Objectives: This study sought to assess the relationship between RVGLS and mortality and to compare prognostic performance of RVGLS with conventional echocardiographic indices of right ventricular (RV) systolic function.

Methods: This study identified adults with Ebstein anomaly with echocardiographic assessment of RV systolic function (RVGLS, RV fractional area change [RVFAC], RV tissue Doppler systolic velocity [RV s'], and tricuspid annular plane systolic excursion [TAPSE]) from 2003 to 2020.

Prognostic Value of the Anatomic-Physiologic Classification in Adults With Congenital Heart Disease.

Background: The prognostic role of the congenital heart disease (CHD) anatomic/physiologic classification has not been systematically studied. The purpose of this study was to determine whether CHD physiologic stage provided improvement in prognostic power (to predict all-cause mortality) beyond conventional clinical risk models.

Methods: Retrospective study of adults with CHD at the Mayo Clinic (2003-2019).

Outcomes after implantation of right-sided mechanical valve prostheses in congenital heart disease.

Background: Bioprosthetic valves are often used for pulmonary valve replacement (PVR) and tricuspid valve replacement (TVR) because of concerns about mechanical valve thrombosis in the right heart. The purpose of this study was to assess prosthetic valve function and outcomes (prosthetic valve dysfunction, reoperations and major bleeding events) after mechanical PVR and TVR and to compare these to bioprostheses implanted in the same positions.

Method: Case-control study of adults with congenital heart disease that underwent mechanical TVR or PVR (2003-2021) at Mayo Clinic Rochester, Minnesota.

Right atrial dysfunction is associated with atrial arrhythmias in adults with repaired tetralogy of fallot.

Background: Adults with repaired tetralogy of Fallot (TOF) have right atrial (RA) remodeling and dysfunction, and RA function can be measured using speckle tracking echocardiography. There are limited data about the role of RA strain imaging for risk stratification in this population. We hypothesized that RA reservoir strain can identify TOF patients at risk of developing atrial arrhythmia.

Green Synthesis, Characterization, Antimicrobial and Anticancer Screening of New Metal Complexes Incorporating Schiff Base.

A Schiff base ligand of -vanillin and 4-aminoazobenzene and its transition metal complexes of Ni(II), Co(II), Zn(II), Cu(II), Mn(II), and Zr(IV) were prepared under microwave irradiation as a green approach compared to the conventional method. The structures of new compounds have been characterized and elucidated via elemental and spectroscopic analyses. In addition, magnetic susceptibility, electron spin resonance, and electronic spectra of the synthesized complexes explained their geometrical structures.
