A 65‐year‐old asymptomatic woman, who had been pathologically diagnosed with pulmonary sarcoidosis, was admitted for further evaluation of possible cardiac involvement. Her echocardiography demonstrated the development of apical hypertrabeculation that was not observed 5 years previously. Cardiac magnetic resonance imaging revealed late gadolinium enhancement in the same region. Gallium single photon‐missioned computed tomography/computed tomography revealed high uptake. Therefore, the diagnosis of active cardiac sarcoidosis was established, and subsequent treatment with corticosteroid was initiated. No study regarding acquired left ventricular hypertrabeculation associated with cardiac sarcoidosis has been reported. The integrated multi‐imaging modality approach helped in earlier recognition of cardiac sarcoidosis.

A 56-year-old woman was diagnosed as atrial septal defect (ASD) with pulmonary hypertension; pulmonary blood flow/systemic blood flow (Qp/Qs) of 2.3, pulmonary artery pressure (PAP) of 71/23(39) mmHg and diastolic dysfunction of left ventricle. PAP was improved after medical therapy; therefore, transcatheter ASD closure was performed. Seven days later, left-sided heart failure occurred, however, the improvement of Qp/Qs (1.7) and PAP of 51/21(32) was confirmed. Diuretic therapy was introduced which led to further decrease of PAP 40/12(25) and Qp/Qs (1.1). Because of gradual decrease of Qp/Qs, this patient appeared to be protected from acute pulmonary edema.

Objective This study retrospectively compared the outcomes of emergently admitted patients with aortic stenosis (AS) with or without urgent transcatheter aortic valve replacement (TAVR). Methods Patients hospitalized between February 2015 and December 2019 for symptomatic AS were retrospectively analyzed by comparing the received conservative management [continued medical therapy with or without elective surgical transcatheter replacement (SAVR) or TAVR scheduled after the index hospitalization] and urgent TAVR (TAVR during the index hospitalization). Results The cohort comprised 114 patients with symptomatic AS who required emergency admission. Urgent TAVR was performed for 37 patients, while conservative management was provided for 77 patients, including 1 who received urgent SAVR. Urgent TAVR was more likely to be performed in patients with a history of hospitalization for heart failure, high New York Heart Association class scores, a lower clinical frailty scale at admission, and a high aortic valve peak velocity (p=0.01, p<0.001, p<0.01 and p=0.02, respectively). Kaplan-Meier analyses with log-rank test revealed favorable outcomes of urgent TAVR in all-cause mortality and cardiovascular events within 60 days of admission (p<0.01, p<0.01, respectively). Conclusion Urgent TAVR had better short-term outcomes in patients with symptomatic AS who required emergency hospital admission than conservative management. When considering urgent TAVR, patients with typical heart failure symptoms due to AS with a history of heart failure hospitalization and relatively little frailty can be selected.

Background Conduction disturbances leading to permanent pacemaker implantation (PPI) rarely occur late after transcatheter aortic valve replacement (TAVR). The clinical features of this phenomenon and its association with periprocedural conduction disturbances remain uncertain. Objectives We aimed to determine the incidence and characteristics of late-onset atrioventricular block (AVB) after TAVR. Methods This single-center study included 246 patients undergoing TAVR. Late-onset AVB was defined as AVB ≥1 month after the TAVR. Results Periprocedural AVB (periAVB) occurred in 43 patients (17%). Patients with periAVB had a higher rate of right bundle branch block (47% vs 7%, P < .0001). Of the 43 patients with periAVB, 15 underwent PPI (35%) at a median duration of 6 days, whereas 1 of the remaining 203 patients without periAVB underwent PPI within 1 month (0.5%). During a median follow-up duration of 365 days, late-onset AVB occurred in 10 of 230 patients without PPI within 1 month (4%) at a median duration of 76 days. All 10 patients presented transient periprocedural atrioventricular conduction disturbances, including 8 patients with periAVB (80%), all of whom recovered within 1 month, and 9 patients underwent self-expanding valve implantation (90%). The mortality rate in patients with PPI within 1 month was higher than in those without, although the difference was not statistically significant (hazard ratio 2.68, 95% confidence interval 0.97–9.05, log-rank P = .09). Conclusion Late-onset AVB occurred in a minority of patients undergoing TAVR. Greater vigilance is warranted, particularly in patients with transient conduction disturbances during the periprocedural period following self-expanding valve implantation.

Purpose In the era of COVID-19, those special settings or indications for which standard transthoracic echocardiography (TTE) can safely produce benefits or advantages over minimized ultrasound imaging procedures need to be identified. Thus, the purpose of this study was to conduct a retrospective analysis with offline comprehensive conventional measurement of bilateral heart function and develop an appropriate prognostic model for in-hospital death. Methods We performed a retrospective analysis of 37 consecutive patients with COVID-19, confirmed by real-time reverse-transcriptase polymerase chain reaction assay, who had undergone clinically indicated standard two-dimensional echocardiographic studies in intensive care wards. Offline comprehensive measurement was also performed. We further integrated the echocardiographic findings as paired evidence of vital organ involvement (possible respiratory distress assessed using right ventricular functional parameters, possible myocardial injury assessed using increased wall thickness, effusion or asynergy) and circulatory failure (suspected low flow status assessed using stroke volume index, suspected congestion assessed using elevated right or left atrial pressure). We evaluated its value for in-hospital death along with other echocardiographic findings. Results The most common features included a normal-sized left atrium and left ventricle with preserved left ventricular ejection fraction, despite deteriorated left ventricular flow volume. Less frequent findings, such as abnormalities in the right heart and left ventricular abnormalities suggesting myocarditis, were observed. Although the single echocardiographic parameters failed to show predictive values for in-hospital death, integration of the echocardiographic findings suggested predictive value ( p = 0.04, odds ratio: 12.28). Conclusion Standard TTE at the bedside with offline comprehensive conventional measurement may provide prognostic information that is valuable for the management of patients with COVID-19.

Objectives: To evaluate the feasibility and efficacy of transcatheter aortic valve replacement (TAVR) in patients with small sinus of Valsalva (SOV). Background: Patients with small SOV are considered unfavorable for TAVR since it carries risk of coronary obstruction after valve implantation. Therefore, these patients with small SOV were excluded from previous clinical trials. Methods: Between February 2017 and February 2019, a total of 139 consecutive patients with severe aortic stenosis (AS) undergoing TAVR were prospectively enrolled in the Tokai Valve Registry. Patients with small SOV who were treated with smaller size of self-expandable transcatheter heart valve (THV) than expected by perimeterbased sizing were included in this study. Eleven patients (7.9%) were included. Results: Mean age was 86.5 ± 3.8 years and median STS Score was 8.5% (interquartile range: 6.3-12.3%). Device success was accomplished in all patients and no coronary obstruction was observed. No moderate/severe paravalvular leakage, new onset conduction disturbance, and new permanent pacemaker implantation were noted. At 30-day follow-up, mean aortic valve gradient was 6.9 ± 1.7 mmHg and mean indexed aortic valve area was 0.95 ± 0.16 cm 2 /m 2. Prosthetic valve performance was stable at 12-month follow-up. No severe prosthesis patient mismatch was documented at any time point. No in-hospital, 30-day, and 12-month mortality were observed. The median follow-up was 711 days (IQR: 547-803 days), and no patient was lost to follow-up. Conclusions: Our preliminary experience suggests favorable safety and efficacy of TAVR utilizing self-expandable THV with intentional down-sizing in patients with severe AS and small SOV in a mid-term follow-up.
