BACKGROUND: Various mitral repair techniques have been described. Though these repair techniques can be highly effective when performed correctly in suitable patients, limited quantitative biomechanical data are available. Validation and thorough biomechanical evaluation of these repair techniques from translational large animal in vivo studies in a standardized, translatable fashion are lacking. We sought to evaluate and validate biomechanical differences among different mitral repair techniques and further optimize repair operations using a large animal mitral valve prolapse model...

Background: Mitral regurgitation (MR) is a common heart valve disease, causing many serious complications in several organ systems, especially the cardiovascular system. The 2D speckle tracking echocardiography (STE) is a new technique for detecting potential cardiac dysfunction when only tissue function abnormalities are present. The study aimed to assess left ventricular (LV) systolic function early by STE in patients with primary MR through global LV deformity along the global longitudinal strain (GLS). Methods: An analytical cross-sectional study was performed on 46 patients with moderate to severe primary MR as recommended by the American Society of Echocardiography (ASE) 2017...

Patent foramen ovale (PFO) complicated with carcinoid heart disease (CHD) can cause severe hypoxia and worsening clinical conditions. We report the case of a patient with CHD in poor general condition with multiple severe valve regurgitations and PFO, who underwent successful percutaneous closure of the PFO.

Cardiology and all its subspecialties continue to push the envelope in developing new treatment strategies for a wide variety of diseases. After screening more than 1300 articles, we highlight a selection of important cardiology articles published in 2023. Starting with prevention, we note articles that look at the effect of semaglutide in patients with obesity as well as a first-in-class drug, bempedoic acid, on cardiovascular outcomes. We have also examined new evidence comparing conservative management with invasive management of frail, older patients with non-ST-segment elevation myocardial infarction (NSTEMI)...

IMPORTANCE: The overall prevalence of mitral valve replacement (MVR) or MV repair at the time of cardiac surgery in the setting of isolated anterior mitral leaflet degenerative pathologic status in the US population is unknown. OBJECTIVE: To investigate the prevalence of MVR and MV repair using the Society of Thoracic Surgeons' Adult Cardiac Surgery Database. DESIGN, SETTING, AND PARTICIPANTS: In a cross-sectional study, all patients diagnosed with isolated anterior mitral leaflet degenerative regurgitation who underwent either surgical MVR or MV repair between July 1, 2011, and June 30, 2022, were identified...

BACKGROUND: Mitral valve prolapse (MVP) is a heart valve anomaly with specific electrocardiographic findings and arrhythmia. A predominant sympathetic tone and diminished vagal activity have been reported especially in symptomatic MVP patients. OBJECTIVES: In the current study, we aim to review heart rate variability (HRV) parameters of MVP children in order to determine if there is an impaired autonomic regulation. METHODS: The data of children with MVP were retrospectively analyzed...

METHODS: A dataset of the locally treated patients in a randomized controlled trial comparing POEM with pneumatic dilation (PD) was analyzed. A BOM is defined as a >50% increase in esophageal diameter at its widest point in the distal esophagus between the lower esophageal sphincter and 5 cm above. RESULTS: 74 patients were treated in our center, 5-year follow-up data was available in 55 patients (32 (58%) patients randomized to POEM, 23 (42%) PD). In the group initially treated with POEM the incidence of BOM increased from 11...

BACKGROUND: Connective tissue disease (CTD) is the second most common cause of the pulmonary arterial hypertension (PAH). Currently, clinical data concerning CTD-PAH is scarce. Our study aimed to assess the efficacy and safety of macitentan in the treatment of CTD-PAH. METHODS: In this retrospective study, patients diagnosed with CTD-PAH at The First Affiliated Hospital of Soochow University from April 2020 to November 2021 were included. Of the patients, 9 were switched to macitentan monotherapy whereas 23 received initial combination therapy...

BACKGROUND: Although it is known that mitral regurgitation (MR) in patients with myocardial infarction (MI) may increase the right ventricular (RV) afterload, leading to RV dysfunction, the exact detrimental effects on RV function and myocardial peak strain remain unresolved. In this study, we assessed the impact of MR on the impairment of RV myocardial deformation in patients with MI and explored the independent influential factors of RV peak strain. METHODS: A total of 199 MI participants without or with MR were retrospectively assessed in this study...

BACKGROUND: Thoracoabdominal aortic aneurysms (TAAAs) are rare but complicated aortic pathologies that can result in high morbidity and mortality. The whole-aorta hemodynamic characteristics of TAAA survivors remains unknown. This study sought to obtain a comprehensive view of flow hemodynamics of the whole aorta in patients with TAAA using four-dimensional flow (4D flow) magnetic resonance imaging (MRI). METHODS: This study included patients who had experienced TAAA or abdominal aortic aneurysm (AAA) and age- and sex-matched volunteers who had attended China Hospital from December 2021 to December 2022 in West...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become widely used in recent years, However, there is also an increasing need for removal of TAVR valves due to prosthetic valve dysfunction (PVD) and the development of infective endocarditis. Surgical aortic valve replacement (AVR) for these patients is risky due to the original patient background and anatomic conditions. Intuity rapid deployment aortic valve (Edwards Lifesciences, Irvine, CA) replacement would be useful for such high risk patients to prevent longer cardiac arrest time and obtain good hemodynamic results...

BACKGROUND: Females with mitral valve disease have higher rates of tricuspid regurgitation(TR) than males. While tricuspid valve repair(TVr) decreases progression of TR, we hypothesize that there may be sex-based differences in concomitant TVr at the time of mitral surgery. METHODS: Adults undergoing mitral surgery for degenerative disease with moderate or worse preoperative TR at a high-volume center from 2014-2023 were identified. Patients with previous tricuspid intervention were excluded...

BACKGROUND: Surgically repaired tetralogy of Fallot (TOF) is a congenital heart disease with a cumulative survival rate of 72% in the 4th decade of life in longitudinal single-cohort studies. Debate surrounds conservative versus surgical management in adults with TOF once pulmonary regurgitation occurs.

Despite advances in multidisciplinary acute care for myocardial infarction (MI), the clinical need to manage heart failure and elevated mortality risks in the remote phase of MI remains unmet. Various prognostic models have been established using clinical indicators obtained during the acute phase of MI; however, most of these indicators also show chronic changes in the post-MI phase. Although relevant guidelines recommend follow-up assessments of some clinical indicators in the chronic phase, systematic reassessment has not yet been fully established and implemented in a real-world clinical setting...

Transcatheter heart valve replacements (TVR) are mostly designed in a closed position (c) with leaflets coaptating. However, recent literature suggests fabricating valves in semi-closed (sc) position to minimize pinwheeling. With about 100,000 children in need of a new pulmonary valve each year worldwide, this study evaluates both geometrical approaches in adult as well as pediatric size and condition. Three valves of each geometry were fabricated in adult (30 mm) and pediatric (15 mm) size, using porcine pericardium...
