ABSTRACT Introduction Stability of catheter‐tissue contact in the robotic magnetic navigation (RMN) system is one key features that distinguishes this from manually guided catheters. Numerous studies have shown force (CF) controlled catheters as crucial for forming an optimal lesion duration application or power. Catheters used RMN lack a quantitative method intraoperative monitoring parameter. Our study aims to partially address gap scientific knowledge. Methods We conducted total 1200 CF...
ABSTRACT Introduction Catheter ablation (CA) is a preferred treatment for atrial fibrillation (AF), often outperforming antiarrhythmic medications in maintaining sinus rhythm and managing symptoms. One of the most important features any method, alongside its effectiveness, safety. Methods This study evaluates 180‐day all‐cause mortality rates post‐ablation using data from National Health Fund Poland (NHF‐P), encompassing over 99% AF CAs 100% deaths 2012 to 2019. Results Our analysis, which...
Data are limited on the clinical manifestations and outcomes of acute myocarditis from a large-scale registry. We investigated myocarditis's characteristics prognosis large-scale, multi-center registry in Republic Korea. collected data seven hospitals between 2001 2021. Clinical variables during index hospitalization follow-up periods were analyzed. also evaluated inter-center temporal differences diagnostic treatment patterns. Eight hundred forty-one patients diagnosed with included. Common...
Several cases involving severe right ventricular (RV) failure in advanced cancer patients have been found to be pulmonary tumor thrombotic microangiopathies (PTTMs). This study aimed discover the nature of rapid RV syndrome with a suspected diagnosis PTTM for better diagnosis, treatment, and prognosis prediction clinical practice.From 2011 2021, all clinically were derived from one tertiary hospital more than 2000 in-hospital bed.A total 28 biopsy confirmed case included. The most common...
Background: Although early atrial fibrillation (AF) events during the blanking period after AF ablation are risk factors for late recurrence, data on predictors of recurrence in patients who experience limited. In this study, we investigated implications left (LA) strain with respect to long-term outcomes experiencing totally thoracoscopic (TTA). Methods: A total 128 underwent TTA between 2012 and 2015 were enrolled from a tertiary center. Peak longitudinal LA was measured preoperatively....
The incidence of venous thromboembolism is increasing, and it more common in older than younger patients. Inferior vena cava (IVC) thrombosis a rare subtype deep vein thrombosis, associated with high arterial patients systemic lupus erythematosus (SLE). We present the case 25-year-old female patient large IVC caused by SLE that was intractable to thrombolytic therapy.
Abstract Aims Tricuspid valve (TV) surgery for functional tricuspid regurgitation (TR) is becoming more common, but the associated mortality remains high. Therefore, we evaluated clinical and echocardiographic parameters with all‐cause in patients severe TR who underwent TV surgery. Methods results A total of 286 replacement or repair was analysed between January 2006 December 2017. We assessed changes conventional strain, such as peak atrial longitudinal strain (PALS). During a median...
Left atrial (LA) fibrosis is related with development and severity of fibrillation (AF). The aim this study was to investigate the association between LA strain in patients undergoing totally thoracoscopic ablation (TTA) for AF.Between February 2012 March 2015, a total 128 who underwent TTA were enrolled from tertiary hospital. appendage (LAA) harvested during surgery determine degree fibrosis. LAA classified as mild (1st quartile), moderate (2nd 3rd or severe (4th quartile). Clinical...
There are limited data about predictors of atrial fibrillation (AF) recurrence after totally thoracoscopic ablation (TTA). This study investigated the clinical implication left appendage emptying velocity (LAAV) in patients undergoing TTA.
The number of trans-catheter aortic valve replacement (TAVR) procedure is increasing; However, the incidence leaflet thrombosis higher in TAVR than surgical (SAVR). In this study, risk factors for after and its effects on hemodynamics clinical course were investigated.Multidetector computed tomography (MDCT) was performed at 1year 94 patients from January 2015 to October 2020 Samsung Medical Center South Korea. Among patients, subclinical occurred 20 analyzed. addition, difference (AV)...
The current study sought to evaluate whether long-term clinical outcomes according the use of dual antiplatelet therapy (DAPT) or single (SAPT) differed between acute coronary syndrome (ACS) and stable ischaemic heart disease (SIHD) patients who underwent artery bypass grafting surgery (CABG).Between January 2001 December 2017, 3199 with ACS (55.3%) 2583 SIHD (44.7%) isolated CABG were enrolled. population was stratified using DAPT SAPT in patients. primary outcome a cardiovascular death...
Cardiac involvement is the main prognostic determinant in AL amyloidosis. We sought to determine significance of longitudinal change left ventricular (LV) global strain (GLS) cardiac light chain (AL) amyloidosis patients undergoing chemotherapy.
Recurrence of any atrial arrhythmia after surgical ablation is known as a negative predictor cardiovascular events and total mortality. However, there have been no focused studies for fibrillation (AF) recurrence prediction in patients with significant tricuspid regurgitation (TR), the risk-benefit estimation valve (TV) surgery not fully established.We screened 385 who underwent TV operation between 2001 2017. After excluding did undergo maze operation, 158 were enrolled. Enrolled divided by...

Background Aortic stenosis (AS) is a representative geriatric disease, and there an anticipated rise in the number of patients requiring noncardiac surgeries with AS. However, still lack research on primary predictors perioperative complications asymptomatic significant Methods Results Among cohort under general anesthesia, intermediate to high risk surgery from 2011 2019, at Samsung Medical Center, 221 were identified have First, examine impact AS adverse events, occurrences major...
Background Although peripartum cardiomyopathy (PPCM) is a fatal disease affecting young patients and fetuses, little known about its recent prognosis risk factors. This study investigated temporal trends in clinical characteristics outcomes for PPCM nationwide multicenter registry. Methods Results The population comprised 340 (mean age, 33 years) who were diagnosed with between January 2000 September 2022 26 tertiary hospitals South Korea. was defined as heart failure left ventricular...
