We aimed to investigate whether thrombus aspiration could preserve the index of microcirculatory resistance (IMR) after primary percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI).Sixty-three STEMI were randomised into two groups: PCI (aspiration group, n=33) and without (non-aspiration n=30). IMR was measured using a pressure-temperature sensor-tipped wire. Echocardiography performed at baseline six-month follow-up. No significant differences...
Background Left atrial (LA) remodeling is associated with adverse cardiovascular events, including heart failure (HF) and stroke in patients fibrillation (AF). However, there are limited data on the value of right (RA) this population. We investigated prognostic role RA enlargement non-valvular AF. Methods results analyzed 254 consecutive (age = 69 ± 12years, male:female 165:89, mean left ventricular ejection fraction 58.0 7.2%) AF who underwent two-dimensional echocardiography from a single...
Background: Percutaneous mitral valvuloplasty (PMV) is a standard treatment for severe rheumatic stenosis (RMS). However, the prognostic significance of change in valve area (∆MVA) during PMV not fully understood.
Aortic valve replacement (AVR) is considered a class I indication for symptomatic severe aortic stenosis (AS). However, there little evidence regarding the potential benefits of early AVR in patients diagnosed with normal-flow, low-gradient (NFLG) AS.Two-hundred eighty-one NFLG AS (stroke volume index ≥35 mL/m², mean transaortic pressure gradient <40 mmHg, peak velocity <4 m/s, and area <1.0 cm²) between January 2010 December 2020 were included this retrospective study. After performing 1:1...
We aimed to identify mechanical and pharmacological revascularization strategies correlated with the index of microcirculatory resistance (IMR) in ST-elevation myocardial infarction (STEMI) patients.Microvascular dysfunction (MVD) after STEMI is infarct size poor long-term prognosis, IMR a useful analytical method for quantitative assessment MVD. However, therapeutic that can reliably reduce MVD remain uncertain.Patients who underwent primary percutaneous coronary intervention (PCI) were...
Background Rheumatic mitral stenosis is a significant cause of valvular heart disease. Pulmonary arterial systolic pressure (PASP) reflects the hemodynamic consequences and used to determine treatment strategies. However, PASP progression expected outcomes based on changes in patients with moderately severe remain unclear. Methods Results A total 436 rheumatic (valve area 1.0-1.5 cm
Ivabradine is a selective inhibitor of the sinoatrial node "funny" current, prolonging slow diastolic depolarization. As it has ability to block heart rate selectively, more effective at faster rate. It recommended for treatment failure reduced ejection fraction in presence beta-blocker therapy further reduction However, previous reports have shown association Torsade de pointes (TdP) with concurrent use ivabradine and drugs resulting QT prolongation or blockage metabolic breakdown...
The rapid economic development of South Korea provides a unique model to study changes in the clinical characteristics, treatment approaches, and outcomes patients with rheumatic mitral stenosis (MS) relative socioeconomic growth.
Abstract Background Rheumatic heart disease (RHD) is a major global health issue because of its potential to cause failure. While RHD has been reported more frequently in women, this case report highlights the clinical manifestations, diagnosis, and management rheumatic multivalvular young Asian male. Case summary A 46-year-old man with history percutaneous mitral valvuloplasty (PMV) was admitted dyspnoea generalized oedema that severely hindered his quality life. Transthoracic...
We aimed to examine the prevalence of burnout among imaging cardiologists in Korea and identify its associated factors. An online survey affiliated with university hospitals was conducted using SurveyMonkey® November 2023. The validated Korean version Maslach Burnout Inventory-Human Service Survey used assess across three dimensions: emotional exhaustion, depersonalization, lack personal accomplishment. Data on demographics, work environment factors, job satisfaction were collected...
Improvement of left ventricular (LV) diastolic dysfunction (DD) is known to be a good prognostic factor in patients with heart failure reduced ejection fraction (EF). In the present study, we investigated predisposing risk factors affecting reversibility LV filling pattern (DFP) preserved EF.
This study compared echocardiography (echo) and cardiac computed tomography (CT) in measuring the Wilkins score evaluated potential added benefit of CT predicting immediate percutaneous mitral valvuloplasty (PMV) outcomes rheumatic stenosis (MS) patients deemed eligible for PMV by echo.
Abstract The management and follow-up of moderate aortic stenosis (AS) lacks consensus as the progression patterns are not well understood. This study aimed to identify hemodynamic AS, associated risk factors outcomes. We included patients with AS at least three transthoracic echocardiography (TTE) studies performed between 2010 2021. Latent class trajectory modeling was used classify groups distinctive trajectories, which were determined by serial systolic mean pressure gradient (MPG)...
Evidence regarding the efficacy and safety of intracardiac echocardiography (ICE) for guidance during transcatheter aortic valve replacement (TAVR) is limited. This study aimed to compare clinical ICE versus transesophageal (TEE) guiding TAVR.
This study aimed to elucidate the relationship between premature ventricular complexes (PVCs) and right (RV) dysfunction, effects of radiofrequency catheter ablation (RFCA) on RV function.A total 110 patients (age, 50.8 ± 14.4 years; 30 men) without structural heart disease who had undergone RFCA for outflow tract (RVOT) PVCs were retrospectively included. function was assessed using fractional area change (FAC) global longitudinal strain (GLS) before after RFCA. Clinical data compared...
There are insufficient data regarding the risk factors associated with valve dysfunction of bioprosthetic valves in mitral position This study aimed to investigate (MV) (MVD).A total 245 patients (age 67.2±11.2 years, 74.9% women) who were followed up for more than 5 years after surgical MV replacement analysed setting retrospective design. MVD was defined as an increased mean gradient >5 mm Hg limited leaflet motion and/or newly developed regurgitation at least moderate severity on...
Introduction: Mitral stenosis (MS) severity is determined by mitral valve area (MVA); the threshold for severe MS was raised from MVA of 1.0 cm 2 to 1.5 in recent guidelines. Hypothesis: This study aimed compare clinical outcomes, according percutaneous valvuloplasty (PMV) versus replacement (MVR) treatment strategy, patients with updated criteria subgroups categorized and . Methods: From Multicenter mitrAl STEnosis Rheumatic etiology (MASTER) registry 3,140 patients, we included who...
Introduction: Percutaneous mitral valvuloplasty (PMV) is an established treatment for severe rheumatic stenosis (RMS). However, there limited data on the clinical significance of valve area change (ΔMVA) during PMV prognosis. Hypothesis: The prognosis improves with greater post-procedure ΔMVA. Methods: Data from Multicenter mitrAl STEnosis Rheumatic etiology (MASTER) registry, which included 3,140 patients at least moderate RMS were analyzed. Out those, (MVA < 1.5 cm 2 ) who underwent...
Introduction: Aortic valve replacement (AVR) is a class I indication for symptomatic severe aortic stenosis (AS). However, there little evidence of the benefit early AVR in patients with normal-flow, low-gradient (NFLG) AS. Hypothesis: Early has NFLG AS Methods: Two-hundred eighty-one diagnosed (stroke volume index ≥ 35 mL/m 2 , mean transaortic pressure gradient < 40 mmHg, peak velocity 4 m/s, and area 1.0 cm ) between January 2010 December 2020 were retrospectively reviewed.
