Transcatheter aortic valve implantation (TAVI) has been recognized as a standard therapy for severe aortic valve stenosis. However, since some patients who receive TAVI have poor outcomes, the predictors of clinical outcomes after TAVI are important. The aim of this study was to investigate the association between appetite and long-term clinical outcomes. We screened consecutive cases who received TAVI at our medical center between July 2014 and October 2018. A total of 139 patients who received transfemoral TAVI were included as the final study population. They were divided into a good appetite group (n = 105) and a less appetite group (n = 34) according to their dietary intake rate (> 90%: good appetite group, !90%: less appetite group). We defined the intake rate as the average for breakfast, lunch, and dinner on the day just before discharge. We defined two-year major adverse cardiovascular and cerebrovascular events (MACCE) as a composite of cardiovascular death, myocardial infarction, any coronary revascularization, history of hospitalization due to heart failure, and disabling acute cerebral infarction. Kaplan-Meier analyses and multivariate Cox regression analysis were performed. The median duration of the follow-up period was 372 (189-720) days. Kaplan-Meier curves showed that the less appetite group got MACCE more frequently (event free rate of the less appetite group: 76.5% versus the good appetite group: 94.3%, Log Rank P = 0.01). In multivariate Cox regression analysis, having less appetite was a significant predictor of two-year MACCE (HR 5.26, 95%CI 1.66-16.71, P < 0.01). In conclusion, among the patients who received transfemoral TAVI, appetite status just before discharge was significantly associated with long-term outcome.

Postcatheterization pseudoaneurysm is a serious complication following diagnostic or therapeutic catheterization. Because radial access is unsuitable in some situations, there is still a need to use femoral or brachial access for arterial catheterization. The aim of this study was to compare the incidence and clinical characteristics of pseudoaneurysm between brachial and femoral access. We identified patients who underwent arterial catheterization from our cardiac catheter records. A total of 5,990 cardiac catheter records and discharge summaries were reviewed, and 23 pseudoaneurysm cases were identified. Those pseudoaneurysm cases were divided into a brachial pseudoaneurysm group (n = 9) and a femoral pseudoaneurysm group (n = 14). The incidence of pseudoaneurysm was significantly higher in brachial access than in femoral access (odds ratio: 4.16, 95% confidence interval: 1.80-9.65; P < 0.001). Successful manual compression was frequently achieved in both the brachial (77.8%) and the femoral (92.9%) pseudoaneurysm groups (P = 0.295). Surgical intervention was more frequently performed in the brachial pseudoaneurysm group (22.2%) than in the femoral pseudoaneurysm group (0%) without reaching statistical significance (P = 0.07). Moreover, neurological disorders were observed only in the brachial pseudoaneurysm group (22.2%). In conclusion, the incidence of pseudoaneurysm was significantly higher in brachial access than in femoral access, indicating the potential risk of brachial access. Successful manual compression was frequently achieved in both groups, but neurological disorders were observed only in brachial access, suggesting the greater risk of brachial pseudoaneurysms.

Cases in which an anomalous single coronary trunk arises from the ascending aorta are extremely rare. In percutaneous coronary intervention for the lesion of a coronary artery anomaly, several problems may occur, including selection of a guide catheter, insufficient backup force, and difficulties of stent delivery. The GuideLiner catheter, which is a coaxial guide extension having the advantage of rapid exchange, facilitates coronary intervention for complex lesions. We report a case of angina having a lesion in the left anterior descending artery of a single coronary trunk arising from the ascending aorta. We successfully performed revascularization by using the GuideLiner catheter.

Careful auscultation is the first step to diagnose aortic stenosis (AS). The aim of this study was to compare clinical outcomes following transcatheter aortic valve implantation (TAVI) between the patients primarily diagnosed by heart murmur and those diagnosed by other reasons. We retrospectively included 258 patients who underwent TAVI in our medical center, and divided those into the murmur group (n = 81) and the other-reason group (n = 177) according to the primary reason for AS diagnosis. The primary endpoint was the major adverse cardiovascular and cerebrovascular events (MACCE), which was defined as the composite of cardiovascular death, hospitalization due to acute decompensated heart failure, and disabling stroke. The murmur group included younger patients than the other-reason group (82.8 year-old vs. 84.0 year-old, P = 0.02). History of AF was more frequently observed in the other-reason group than in the murmur group (21.5% vs. 7.4%, P <0.01). STS score and logistic EuroSCORE were lower in the murmur group than in the other-reason group (STS: 4.7% vs. 7.2%, P <0.01, logistic EuroSCORE: 8.3% vs. 11.2%, P <0.01). The median follow-up period was 562 days. MACCE was more frequently observed in the other-reason group than in the murmur group (27.7% vs. 9.9%, Log Rank P <0.01). The multivariate COX hazard analysis revealed that the AS patients primarily diagnosed by heart murmur was inversely associated with MACCE (HR 0.38, 95%CI 0.17–0.86, P = 0.020). Among AS patients who underwent TAVI, the patients primarily diagnosed by heart murmur were significantly associated with favorable long-term clinical outcomes.
