The mechanistic interaction between mechanical dyssynchrony and filling pressure in cardiac resynchronization therapy candidates
Both left ventricular (LV) mechanical dyssynchrony and filling pressure have been shown to be associated with outcome in heart failure patient treated with cardiac resynchronization therapy (CRT).
Qualitative and Quantitative Assessment of Atrial Functional Mitral Regurgitation: analysis from the REVEAL-AFMR registry
The prevalence, characteristics, and prognosis of atrial functional mitral regurgitation (AFMR) based on severity remain unclear. No studies have systematically evaluated quantitative thresholds, such as effective regurgitant orifice area (EROA) or regurgitant volume, in relation to outcomes in AFMR. This multicenter study aimed to clarify the clinical implications of both qualitative and quantitative assessments of AFMR severity.

Microvascular resistance reserve in relation to total and vessel-specific atherosclerotic burden
The relationship between coronary artery atherosclerosis and microvascular resistance remains unclear. This study aims to clarify the relationship between total atherosclerotic and vessel-specific atherosclerotic burden and microvascular resistance reserve (MRR).
Incremental Prognostic Value of Left Ventricular and Left Atrial Strain in Moderate Aortic Stenosis
Patients with moderate aortic stenosis (AS) show a poor prognosis if they have high-risk features. We investigated the incremental prognostic value of left ventricular (LV) and left atrial (LA) strain in patients with moderate AS.
Interrupted Aortic Arch with Complete Atrioventricular Canal Defect: Insights from CT Imaging
Prognostic implication of DPD quantification in transthyretin cardiac amyloidosis
Quantification of cardiac [99mTc]-3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) uptake enhances diagnostic capabilities and may facilitate prognostic stratification in patients with transthyretin cardiac amyloidosis (ATTR-CA). This study aimed to evaluate the association of quantitative left ventricular (LV) DPD uptake with myocardial structure and function, and their implications on outcome in ATTR-CA.

High-risk features in non-culprit lesions and clinical outcome after NSTEMI versus STEMI
Complete non-culprit (NC) revascularization may help reduce recurrent events after NSTEMI, especially if NC lesions would harbor high-risk plaque features similar to STEMI. The study aimed to assess differences in fractional flow reserve (FFR)-negative NC plaque morphology in patients presenting with NSTEMI versus STEMI and assess the association of high-risk plaque morphology and clinical outcome.
Long-Term outcomes after stress echocardiography in real world practice: five-year follow-up of the UK Evarest study
Stress echocardiography is widely used to assess patients with chest pain. The clinical value of a positive or negative test result to inform on likely longer-term outcomes when applied in real world practice across a healthcare system has not been previously reported.
Prognostic Implications and Reversibility of Pulmonary Vascular Resistance Derived by Echocardiography in Patients Undergoing Tricuspid Annuloplasty
Pulmonary vascular resistance (PVR) intimately correlates with right ventricular afterload and the development of secondary tricuspid regurgitation (sTR).

Accuracy of left ventricular mechanical dyssynchrony indices for mechanical characteristics of left bundle branch block using cardiovascular magnetic resonance feature tracking
More than 90% of patients with left bundle branch block (LBBB) and reduced left ventricular (LV) ejection fraction have LV dyssynchrony and a high probability of response to cardiac resynchronization therapy (CRT). A subgroup of patients with non-specific intraventricular conduction delay (IVCD) have a LBBB-like LV activation pattern when studied using invasive mapping and advanced echocardiographic techniques. These patients also frequently benefit from CRT but these patients have proven difficult to identify using ECG criteria. Cardiovascular magnetic resonance (CMR) imaging indices of dyssynchrony may identify patients with IVCD who may benefit from CRT but their relative accuracies for identification of LV dyssynchrony remains unknown. We compared the LV dyssynchrony classification accuracy of two commonly available CMR indices in a study population of patients with severely reduced LV ejection fraction and no scar, and either LBBB or normal conduction (normal QRS duration and axis, controls).
