Article Abstract
Background: Stiff left atrial syndrome is a well-established cause of heart failure symptoms. A parallel entity involving the right atrium (RA) has not previously been described. We present a case of refractory right heart failure (RHF) 12 years following orthotopic heart transplantation.
Case Summary: Patient underwent annuloplasty ring placement for severe tricuspid regurgitation in 2018 and kidney transplantation in 2020. The use of multimodality imaging and a multidisciplinary approach suggested a stiff RA as a potential etiology to refractory symptoms. Redo-heart and kidney transplantation in March 2021 led to the resolution of symptoms without recurrence.
Discussion: We propose stiff right atrial syndrome that may need to be considered in the setting of refractory RHF primarily suggested by significant right atrial enlargement and restrictive physiology.

World J Gastroenterol

Background: Cardiopulmonary changes in noncirrhotic portal hypertension (NCPH) are poorly understood.
Aim: To investigate cardiopulmonary changes using transthoracic echocardiography (TTE) in NCPH and their correlation with clinical features.
Methods: Prospective cohort including 10 preclinical NCPH [without portal hypertension (PH)] and 32 NCPH subjects who underwent TTE with agitated saline injection and comprehensive clinical evaluation were assessed.

Background Exploring longitudinal associations of blood biomarkers with left atrial (LA) structure and function can enhance our understanding of atrial fibrillation (AF) etiopathogenesis. Methods We studied 532 participants of the PREDIMED-Plus trial, a multicenter randomized trial in overweight and obese adults with metabolic syndrome. At baseline, 3 and 5 years after randomization, participants underwent transthoracic echocardiography and provided blood for serum biomarker measurements (propeptide of procollagen type I (PICP), high-sensitivity (hs) troponin T (hsTnT), hs C-reactive protein (hsCRP), 3-nitrotyrosine (3-NT), and N-terminal propeptide of B-type natriuretic peptide (NT-proBNP)).

Background: Paroxysmal atrial fibrillation (AF) may underlie some embolic strokes of undetermined source (ESUS), but the widespread use of loop recorders (LRs) to detect it may not be cost-effective. This study evaluated whether assessing left atrial (LA) function by speckle tracking echocardiography (STE) could help to identify ESUS patients most likely to benefit from LR monitoring for AF detection.
Methods: Consecutive ESUS patients diagnosed between 2020 and 2023, who underwent LR implantation and comprehensive echocardiographic evaluation, including STE, were enrolled.
Isometric exercise training in patients with heart failure with preserved ejection fraction: A randomised controlled study.
Eur J Prev Cardiol

Department of Cardiology, St George's University Hospitals NHS Foundation Trust, Blackshaw Road, Tooting, London, UK.
Aim: Heart failure with preserved ejection fraction (HFpEF) is a complex clinical condition associated with poor health-related quality of life and high mortality rates. Limited therapeutic options highlight the need for innovative approaches. Isometric exercise training (IET) produces cardiovascular benefits; however, the effects of IET in patients with HFpEF have not yet been studied.
