Background Nationwide data on transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in Japan are scarce. Methods and Results Using a nationwide inpatient database, we analyzed patients undergoing TAVI (n=8,338) or SAVR (n=16,298) due to aortic stenosis between 2014 and 2017. The annual number of TAVI increased rapidly from 2014 to 2017, particularly in older patients. In-hospital deaths were lower and the length of hospital stay was shorter for patients undergoing TAVI than SAVR. Conclusions TAVI has been penetrating in Japan as an alternative therapeutic option for aortic stenosis and is associated with acceptable clinical outcomes.Background The effect of symptoms on clinical outcomes after deferral of revascularization based on fractional flow reserve (FFR) remains poorly understood. Methods and Results From the J-CONFIRM (Long-Term Outcomes of Japanese Patients With Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter) Registry, this study evaluated 1,215 patients with stable coronary artery disease, including symptomatic and asymptomatic patients (n=571 and 644, respectively). The primary endpoint was the cumulative 2-year incidence of target vessel failure (TVF), including cardiac death, target vessel-related myocardial infarction (TVMI), and clinically driven target vessel revascularization (CDTVR). An inverse probability weighted analysis was performed to adjust for the differences in baseline clinical characteristics between the 2 groups. At 2 years, the TVF rate did not differ significantly between symptomatic and asymptomatic patients (6.5% vs. 4.9%, respectively; P=0.15) or between symptomatic and asymptomatic patients with lesions with an FFR ≤0.80 (8.0% vs. 12.3%, respectively; P=0.20). Conversely, symptomatic patients showed significantly higher rates of TVF (6.2% vs. 3.3%; P=0.01) and CDTVR (6.2% vs. 3.1%; P=0.009) than asymptomatic patients, regardless of negative FFR values (>0.80). Conclusions Despite negative FFR values, symptomatic patients were at higher risk of TVF than asymptomatic patients, driven primarily by a higher rate of CDTVR. https://www.selleckchem.com/products/ml-si3.html Conversely, those with a positive FFR were likely to develop TVF regardless of their symptoms.Background Spontaneous coronary artery dissection (SCAD) is a rare disease that is often misdiagnosed, except in typical cases. Although intracoronary imaging and multislice coronary computed tomography angiography (CCTA) are useful in establishing dissection, they may not be feasible in all instances, especially in small vessels. Methods and Results We describe a series of 7 patients with acute coronary syndrome secondary to small vessel SCAD that was detected only upon repeat coronary angiography (CAG). This cohort had a mean (±SD) age of 50±6 years, was predominantly female (n=6; 86%), and had few coronary risk factors. Three patients (43%) had dissection of the distal segment of the right coronary artery, 3 (43%) had distal left circumflex artery dissection, and 1 patient (14%) had a diagonal branch dissection. None of the patients required percutaneous coronary intervention, and received conservative therapy only, because the infarct area was sufficiently small. No definitive diagnosis of SCAD could be established in any of the patients at first admission because CAG alone or CCTA did not reveal the presence of a flap or intraluminal hemorrhage. However, in such patients without a definitive diagnosis, repeat CAG in the chronic stage showed enlargement of vessels, suggesting the healing of an SCAD. Conclusions Repeat CAG may be useful for suggesting the occurrence of SCAD.Background Using transthoracic echocardiography, including 2D speckle tracking imaging (STI), this study examined cardiac function after domino liver transplantation (DLT) with liver grafts explanted from patients with hereditary amyloidogenic transthyretin amyloidosis. Methods and Results In all, 14 patients who underwent DLT at Kumamoto University Hospital and for whom 2D STI information was available were enrolled in the study; time-dependent echocardiographic changes were evaluated in 7. Although left ventricular (LV) systolic and diastolic function did not differ between the pre- and post-DLT periods (mean [±SD] 5.4±1.0 years after DLT), there were significant (P-14%; odds ratio 28.39, 95% confidence interval 1.89-427.45, P less then 0.05). Conclusions LV systolic and diastolic function was preserved in the long term after DLT. However, 2D STI revealed subtle cardiac dysfunction in DLT recipients, which may be an early manifestation of cardiac amyloidosis.Background We investigated the impact of heart failure (HF) on daily life and satisfaction with current HF medication from the patient perspective in a real-world study in Japan. Methods and Results A cross-sectional survey of 154 HF patients treated by 58 cardiologists was conducted in Japan using patient self-completed questionnaires about their daily life and satisfaction with HF medication, as well as patient record forms completed by their physicians capturing corresponding data. The mean age of patients was 72.7 years. The proportion of patients within New York Heart Association Class I, II, III, and IV was 39%, 44%, 16%, and 1%, respectively. Symptoms reported by patients included dyspnea when active (46%), nocturia (43%), anxiety (18%), and depression (6%). There was a discordance between physician- and patient-reported symptoms, especially for nocturia and inability to sleep. The most frequent lifestyle recommendation from physicians was 'reduce salt/sodium intake', but only 51% of patients receiving this recommendation followed the advice. In all, 44% of patients reported dissatisfaction with their current medication; according to the patients, 27% reported no discussion with their physicians about their prescribed medication, while physicians reported the opposite. Conclusions HF negatively impacts patient daily life. There is discordance between patients and physicians in symptom reporting, lifestyle modification advice and adherence, and reported medication decision making. Gaps in patient-physician communication exist.
