Left ventricular thrombus (LVT) has been identified to be crucial in patients with reduced ejection fraction (EF). Three-dimensional cine phase-contrast magnetic resonance imaging (4D flow MRI) can visualize the intra-LV vortex during diastole and quantify the maximum flow velocity (Vmax) at the apex. In this study, we investigated whether the change in the intra-LV vortex was associated with the presence of LVT in patients with cardiac disease.In total, 36 patients (63.5 ± 11.9 years, 28 men, 12/24 with/without LVT) with diffuse LV dysfunction underwent 4D flow MRI. The relative vortex area using streamline images and Vmax of blood flow toward the apex at the apical left ventricle were evaluated. The correlation between the relative vortex area and Vmax was assessed using Pearson's correlation coefficient. The ability to detect LVT was evaluated using the area under the curve (AUC) of the receiver operating characteristic.The relative vortex area was found to be smaller (27 ± 10% versus 45 ± 11%, P = 0.000026), whereas Vmax at the apical left ventricle was lower (19.1 ± 4.4 cm/second versus 27.4 ± 8.9 cm/second, P = 0.0006) in patients with LVT. Vmax at the apical left ventricle demonstrated significant correlations with the relative vortex area (r = 0.43, P = 0.01) and relative transverse length of the vortex (r = 0.45, P = 0.007). The AUC was 0.91 for the relative vortex area, whereas it was 0.80 for Vmax in the apical left ventricle.A smaller LV vortex and lower flow velocity at the LV apex were associated with LVT in patients with reduced EF.Little is known as regards frailty in patients with functional tricuspid regurgitation (FTR). Thus, in this study, we aimed to investigate the prevalence, characteristics, and impact of frailty on patients with severe FTR.This prospective study included 110 consecutive patients with severe FTR who were assessed via transthoracic echocardiography at an outpatient clinic. Patients were dichotomized using short physical performance battery (SPPB). To better understand the whole picture of frailty in patients with FTR, other frailty scales were also assessed (frailty checklist, clinical frailty scale, gait speed, and Columbia frailty scale). The primary endpoint was the combination of all-cause mortality and heart failure hospitalization.According to each definition of frailty, 28%-46% were identified to be frail. Those with SPPB score of less then 9 were older, had greater New York Heart Association (NYHA) functional classification, and had lower albumin level and estimated glomerular filtration rate compared with those with SPPB score of ≥ 9. They also have smaller tricuspid valve coaptation depth and worse right ventricular fractional area change (RV-FAC) than those with SPPB score of ≥ 9 despite having similar TR severity. The primary endpoint at 1 year was noted in 31% of patients. The SPPB score has excellent discriminatory performance for predicting the primary endpoint (area under the curve 0.82, 95% confidence interval [CI] 0.76-0.91) in receiver operating characteristic analysis and was independently associated with the primary endpoint after adjustment in multivariate analysis (adjusted hazard ratio 0.81, 95% CI, 0.73-0.90; P less then 0.001).Frailty has been widely prevalent in the elderly patient population with FTR; in fact, it has been determined to be strong parameter for poor outcomes.This study assesses the long-term outcomes of patients who suffered from self-expandable transcatheter heart valve (THV) embolized in the aorta in transcatheter aortic valve implantation (TAVI).We retrospectively reviewed the patients with self-expandable THV embolized in the aorta. Follow-up computed tomography was performed to assess the THV migration, struct fractures, and device-related aortic complications.Of the 539 TAVI patients, 11 suffered from self-expandable THV embolized in the aorta. Two patients underwent open-heart surgery to remove the embolized THVs in the ascending aorta. Embolized THVs were repositioned in the aortic arch distal to the left subclavian artery (n = 3) and the thoracic descending aorta (n = 6). Three patients died during a median follow-up time of 40 months. The remaining eight survivors presented with New York Heart Association functional class I or II at the last follow-up. Degeneration of embolized prostheses with thick leaflets and rolled cusp edges was observed in three patients. There was no evidence of valve migration, strut fracture, prosthesis-associated aortic complication, and thrombosis attached on embolized valve for all patients with THVs repositioned in the aorta.Self-expandable THV embolization can be effectively managed in TAVI. Although some embolized valves exhibited leaflet degeneration, the long-term safety of repositioning embolized self-expandable THV in the aorta is assured.Cardiovascular diseases (CVDs) including myocardial infarction (MI) and stroke are often diagnosed in patients with abdominal aortic aneurysm (AAA). However, little has been reported regarding the incidence.Patients with AAA were selected from the National Health Insurance system in South Korea between 2009 and 2015. see more A total of 10,822 participants with a new diagnosis of AAA were included. Propensity score matching by age and sex with patients in whom AAA was not diagnosed was used to select the control group of 32,466 participants. Primary endpoints included the diagnosis of CVD and death. Cox proportional hazard models were used to compare the risk of disease incidence.The incidence of CVD was 16.573 per 1,000 person-years in the AAA group, which was higher than that of the control group's 9.30 per 1,000 person-years. The incidence of MI (hazard ratio [HR], 1.7; 95% confidence interval [CI], 1.479-1.953), stroke (HR, 1.629; 95% CI, 1.443-1.839), and CVD (HR, 1.672; 95% CI, 1.522-1.835) was significantly higher in patients with AAA. Mortality rate was also elevated in the AAA group (HR, 2.544; 95% CI, 2.377-2.722).The incidence of CVD was significantly more frequent in patients with AAA. The AAA group had consistently higher risks regarding CVD and mortality than the control group.During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, patients with ST-elevation myocardial infarction (STEMI) should be treated as possibly infected individuals. Therefore, more time is considered necessary to conduct primary percutaneous coronary intervention (PCI). In this study, we sought to evaluate the impact of the SARS-CoV-2 pandemic on primary PCI for STEMI. Between March 2019 and March 2021, 259 patients with STEMI underwent primary PCI. Patients were divided into 2 groups the pre-pandemic group (March 2019-February 2020) and the pandemic group (March 2020-February 2021). The patient demographics, reperfusion time including onset-to-door time, door-to-balloon time (DTBT), computed tomography (CT), peak creatinine phosphokinase (CPK), and 30-day mortality rate were investigated. The mean age of the patients was 70.4 ± 12.9 years, and 71.6% were male. There were 117 patients before the pandemic and 142 during the pandemic. The median DTBT was 29 (21.25-41.25) minutes before the pandemic and 48 minutes (31-73 minutes) during the pandemic (P less then 0.001). The median door-to-catheter-laboratory time was 13.5 (10-18.75) minutes before the pandemic and 29.5 (18-47.25) minutes during the pandemic (P less then 0.001). CT evaluation was performed before PCI in 39 (33.3%) patients and 63 (44.4%) patients (P = 0.08); their peak CPK levels were 1480 (358-2737.5) IU and 1363 (621-2722.75) IU (P = 0.56), and the 30-day mortality rates were 4.3% and 2.1% (P = 0.48), respectively. The SARS-CoV-2 pandemic changed the diagnostic procedure in the emergency department and affected the DTBT in patients with STEMI. Nonetheless, no adverse effects on the 30-day mortality rate were observed.Follistatin-like protein 1 (FSTL1) is a secreted glycoprotein known for its role in inflammation. However, plasma FSTL1 levels in patients with coronary artery disease (CAD) have not been fully elucidated. Thus, in this study, we investigated the plasma FSTL1 levels of 350 patients who underwent elective coronary angiography. The severity of CAD was represented as the numbers of > 50% stenotic vessels and segments and the severity score. CAD was detected in 196 patients, of whom 84 had 1-vessel disease (1-VD), 62 had 2-VD, and 50 had 3-VD. Plasma high-sensitivity C-reactive protein (hsCRP) levels were higher in patients with CAD than in those without CAD (median 0.56 versus 0.44 mg/L, P 3.6 ng/mL (P less then 0.05). In conclusion, plasma FSTL1 levels in patients with CAD were found to be high and associated with the presence and severity of CAD, thus, suggesting that FSTL1 may play a role in the progression of coronary atherosclerosis.Recent progress in paraganglioma (PGL) revealed genotype-phenotype relationship, especially succinate dehydrogenase complex subunit B (SDHB) gene mutation-related to the extra-adrenal origin and metastasis. SDHB-immunohistochemistry can detect all types of SDH-subunit mutations, and is a useful tool to detect SDH-mutation tumors. PGLs usually occur along with sympathetic, and parasympathetic chains, however, colorectal paraganglioma is extremely rare. We have experienced one sigmoid colon PGL and one rectal PGL. These colorectal PGLs a sigmoid colon PGL measuring 25 mm associated with a gastrointestinal stromal tumor (GIST) of the stomach, and a rectal PGL measuring 75 × 45 mm with elevated norepinephrine level were analyzed by immunohistochemistry for INSM1, chromogranin A, synaptophysin, tyrosine hydroxylase, dopamine-beta-hydroxylase, and SDHB and SDHA. The tumors were strongly positive for above markers, however, negative for SDHB. Both PGLs negative for SDHB immunohistochemistry were defined SDHB-deficient PGLs. Histologic grading of the PGLs by GAPP was well differentiated in sigmoid PGL versus poorly differentiated in rectal PGL. Although these PGLs were the same Stage II of TNM classification, the patient with sigmoid colon PGL had neither recurrence nor metastasis for 5 years after the operation, however, the patient with rectal PGL suffered the recurrent multiple metastases and expired 5 years after the operation. Herein, we compared these colorectal PGLs in regard to the patients' prognostic factors. Patient prognosis with these colorectal PGLs was mostly related to the tumor size and histologic grade under the same situation of SDH-deficiency.

We previously associated acute ST-elevation myocardial infarction (STEMI) with decreased plasma LL-37 levels. Therefore, this study investigated whether plasma LL-37 levels could predict ischemic cardiovascular events in patients after STEMI.

We prospectively collected peripheral plasma samples and clinical and laboratory data from consecutive patients who presented with STEMI and underwent primary percutaneous coronary intervention at Fuwai Hospital between April and November 2017. Enzyme-linked immunosorbent assay measured plasma LL-37 levels, and we followed the patients for 3 years. Major adverse cardiovascular events (MACEs) were a composite of all-cause mortality, reinfarction, unscheduled revascularization, or ischemic stroke.

The study included 302 patients divided into high (≥ median) and low LL-37 level (＜median) groups. The cumulative incidence of MACE (29.1% vs. 12.6%, p=0.0003), all-cause death (12.6% vs. 3.3%, p=0.003), reinfarction (7.1% vs. 2.0%, p=0.04), and unscheduled revascularization (13.
