Enhanced risk stratification in hypertrophic cardiomyopathy through the integration of extracellular volume fraction on cardiovascular magnetic resonance

Hyun‐Jung Lee, Seo‐Yeon Gwak, Suji Lee, Kyu Kim et autres

AIMS: This study investigated the incremental prognostic value of cardiovascular magnetic resonance (CMR)-derived extracellular volume fraction (ECV), a marker of diffuse interstitial fibrosis, beyond late gadolinium enhancement (LGE) in hypertrophic cardiomyopathy (HCM). METHODS AND RESULTS: We analysed 990 consecutive HCM patients (median …

Abstract 4368991: Prognostic Implications of Abnormal Right Ventricular-Pulmonary Artery Coupling Assessed by Three-dimensional Echocardiography in Heart Failure with Preserved Ejection Fraction

Chi Young Shim, Hye Ji Seo, Kyu Kim, Sang Gon Yoon et autres

Background: In advanced stages of heart failure with preserved ejection fraction (HFpEF), right ventricular (RV) function declines, leading to abnormal RV-pulmonary artery (PA) coupling. Current 2D echocardiography only assesses longitudinal function, overlooking RV crescentic geometry and 3D myocardial function. We aimed to …

Microbial Profiling of Saliva, Oral Rinse, Subgingival Plaque and GCF Reveals Site‐Specific Dysbiosis in Periodontitis: A Within‐Subject Comparison of 150 Participants

Ran Lee, Jin‐Young Park, Kyu Kim, Jong‐Won Ha et autres

AIM: This study aimed to compare the microbial communities across four oral sample types-saliva, oral rinse, subgingival plaque and gingival crevicular fluid (GCF)-and to identify disease-associated microbiota in periodontitis. METHODS: Oral samples were collected from 150 adults, each providing four types of …

Thermal‑denatured PDRN exhibits increased in vitro pharmacological activities: A functional role of single‑stranded DNA random coils

Hye-Won Lim, Yuhua Huang, Hye-Seung Baek, Hong-Gyum Kim et autres

Polydeoxyribonucleotide (PDRN) is a DNA‑based remedy that is broadly utilized for the treatment of wounds, inflammatory diseases and other diverse disorders. The present study aimed to clarify which conformational state of PDRNs, single‑stranded DNA (ssDNA) random coil or double‑stranded DNA (dsDNA) helical …

Three-dimensional agitated saline contrast transesophageal echocardiography for the diagnosis of patent foramen ovale

Seo‐Yeon Gwak, Kyu Kim, Hyun‐Jung Lee, Iksung Cho et autres

Patent foramen ovale (PFO) is a three-dimensional (3D) and dynamic structure, making diagnosis challenging with 2D imaging. We aimed to develop a practical 3D agitated saline contrast (ASC) transesophageal echocardiography (TEE) protocol, assess its feasibility, and evaluate its diagnostic implications in ischemic …

Long-Term Follow-Up in Severe Mitral Stenosis With Low Transmitral Diastolic Pressure Gradient: From MASTER Registry

Iksung Cho, Dae‐Young Kim, Jinseob Kim, Ha Jeong Lim et autres

BACKGROUND: Long-term follow-up studies in severe mitral stenosis (MS) with low transmitral mean diastolic pressure gradient (MDPG) are not available. We evaluated the prognostic implications of severe MS with low MDPG in our MASTER (Multicenter Mitral Stenosis with Rheumatic Etiology) registry. METHODS: …

Early predictors of aortic valve surgery in patients with significant bicuspid aortic regurgitation without initial surgical indication

Ha Jeong Lim, Kyu Kim, Seo‐Yeon Gwak, Hyun-Jung Lee et autres

BACKGROUND: Bicuspid aortic regurgitation (AR) is common in younger patients who often do not meet guideline-based criteria for aortic valve (AV) surgery at diagnosis. However, identifying early predictors of disease progression may aid in risk stratification and surgical timing. METHODS: From a …

Ecocardiografía avanzada y análisis de conglomerados para identificar fenogrupos de insuficiencia tricuspídea secundaria con diferente riesgo

Luigi Paolo Badano, Marco Penso, Michele Tomaselli, Kyu Kim et autres

La insuficiencia tricuspídea secundaria (ITS) significativa se asocia a un mal pronóstico, pero su heterogeneidad dificulta la predicción de los resultados de los pacientes. Nuestro objetivo fue identificar fenogrupos pronósticos de ITS. Se analizó a 758 pacientes con ITS moderada a grave: …

Advanced echocardiography and cluster analysis to identify secondary tricuspid regurgitation phenogroups at different risk

Luigi Paolo Badano, Marco Penso, Michele Tomaselli, Kyu Kim et autres

Significant secondary tricuspid regurgitation (STR) is associated with poor prognosis, but its heterogeneity makes predicting patient outcomes challenging. Our objective was to identify STR prognostic phenogroups. We analyzed 758 patients with moderate-to-severe STR: 558 (74 ± 14 years, 55% women) in the …
