Noninvasive myocardial work in severe aortic regurgitation: implications for postoperative left ventricular dysfunction.

Aims: Noninvasive myocardial work offers a promising echocardiographic method to evaluate left ventricular (LV) function as it integrates myocardial deformation and afterload. The study sought to investigate the association of myocardial work indices with post-operative LV dysfunction in patients with chronic severe aortic regurgitation (AR).

Methods And Results: Pre-operative LV ejection fraction (LVEF), LV global work index (LV GWI), LV global constructive work (LV GCW), LV global wasted work (LV GWW), and LV global work efficiency (LV GWE) were measured.

Comparison of clinical and echocardiographic outcomes between mini-thoracotomy transatrial LuX-Valve transcatheter and surgical tricuspid valve replacement.

Background And Aims: Transcatheter tricuspid valve replacement (TTVR) has recently emerged as a novel therapeutic approach for managing severe tricuspid regurgitation (TR). However, surgical tricuspid valve replacement (STVR) continues to be the predominant treatment modality. There are limited comparative data on both procedures.

Risk factors for the recurrence of left atrioventricular valvular regurgitation after surgical repair of partial and transitional atrioventricular septal defect.

Background: Left atrioventricular valvular regurgitation (LAVVR) recurrence after partial and transitional atrioventricular septal defect (AVSD) repair is the main risk factor associated with reoperation or mortality. The purpose of this study was to identify risk factors associated with the recurrence of LAVVR after surgical repair of transitional and partial AVSD at a single institution.

Methods: A hundred and fifty-seven patients who underwent anatomical repair for partial and transitional AVSD from January 2013 to December 2021 were included in our institutional database.

Prognostic Implications of Left Atrial Strain in Bicuspid Aortic Valve With Chronic Aortic Regurgitation.

Background: Left atrial reservoir strain (LARS) is a novel imaging biomarker of left ventricular diastolic dysfunction. This study aimed to examine the prognostic implications of LARS in patients with bicuspid aortic valve and significant (moderate-severe to severe) aortic regurgitation.

Methods And Results: A total of 220 patients with bicuspid aortic valve and significant aortic regurgitation were prospectively enrolled in our study.

Early left ventricular systolic function is a more sensitive predictor of adverse events after heart transplant.

Background: First-phase ejection fraction (EF1) is a novel measure of early changes in left ventricular systolic function. This study was to investigate the prognostic value of EF1 in heart transplant recipients.

Methods: Heart transplant recipients were prospectively recruited at the Union Hospital, Wuhan, China between January 2015 and December 2019.

Noninvasive left ventricular pressure-strain myocardial work in patients with well-functioning bicuspid aortic valves and aortic dilation: a preliminary study.

Background: Noninvasive left ventricular pressure-strain myocardial work (MW) is a novel method for evaluating left ventricular function that integrates myocardial deformation and afterload and has certain advantages over global longitudinal strain (GLS). The study aimed to analyze MW in patients with well-functioning bicuspid aortic valve (BAV) and explore the influences of aortic dilation and arterial stiffness on left ventricular function.

Methods: A total of 104 patients with well-functioning BAVs and 50 controls were enrolled in our study.

Left atrial strain brings new insights for evaluating early diastolic dysfunction in patients with well-functioning bicuspid aortic valve.

Background: Left atrial reservoir strain (LARS) is an early sensor of left ventricular (LV) diastolic dysfunction. Still, the clinical implications of LARS in patients with well-functioning bicuspid aortic valve (BAV) remain unknown.

Materials: The study recruited 103 patients with well-functioning BAV and 50 controls with tricuspid aortic valves.

Transesophageal echocardiography in detecting a dislodged coronary stent.

We report a rare case of coronary stent dislodgement after percutaneous coronary intervention. This case demonstrates the value of two-dimensional and threedimensional transesophageal echocardiography in detecting the dislodged stent at the aortic root and may be beneficial in management.

Echocardiographic diagnosis of rupture of mitral valve papillary muscle.

Objective: To explore the value of echocardiography in diagnosing papillary muscle rupture (PMR) of the mitral valve, and summarize the characteristic echocardiographic features of different types.

Methods: Echocardiograms of 13 PMR patients confirmed by surgery in Wuhan Union Hospital between January 2009 and December 2022 were retrospectively analyzed and their preoperative transthoracic echocardiography (TTE) was compared with surgical findings.

Results: A total of 9020 patients underwent mitral valve repair or replacement surgery during the study period including 13 (0.

Patient-specific computational fluid dynamics for hypertrophic obstructive cardiomyopathy.

Background: The heterogeneous morphologic and functional expression of hypertrophic obstructive cardiomyopathy (HOCM) is evidenced by established imaging, multimodality imaging is essential for a comprehensive assessment but may remain uncertain. This study aimed to develop a patient-specific hemodynamics assessment with cardiac computed tomography angiography (CCTA) based computational fluid dynamics (CFD) and prove its usability in cohorts of HOCM patients.

Methods: A retrospective study was performed on eight HOCM patients with septal myectomy who had both preoperative and postoperative CCTA as well as transthoracic echocardiography (TTE).

Biventricular longitudinal strain as a predictor of functional improvement after D-shant device implantation in patients with heart failure.

Background: The creation of an atrial shunt is a novel approach for the management of heart failure (HF), and there is a need for advanced methods for detection of cardiac function response to an interatrial shunt device. Ventricular longitudinal strain is a more sensitive marker of cardiac function than conventional echocardiographic parameters, but data on the value of longitudinal strain as a predictor of improvement in cardiac function after implantation of an interatrial shunt device are scarce. We aimed to investigate the exploratory efficacy of the D-Shant device for interatrial shunting in treating heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF), and to explore the predictive value of biventricular longitudinal strain for functional improvement in such patients.

An exceedingly rare cause of neonatal shock and the value of point-of-care ultrasound.

We present a case of a 13-day-old neonate with shock who was diagnosed with congenital variation of aortic arch and critical coarctation of aorta by cardiac point-of-care ultrasound. Finally, surgery confirmed the anomalies. This case demonstrates the value of cardiac point-of-care ultrasound in detecting congenital anomalies of great vessels in neonates and may be beneficial in clinical management.
