UNLABELLED: Sudden cardiac arrest during exercise can occur without prior warning signs at rest, highlighting the importance of monitoring for its prevention. To detect the signs of ischemic heart disease, including coronary artery anomalies, ST changes must be detected using three‑lead electrocardiograms (ECGs) corresponding to each region of the three coronary artery branches. We conducted ECG monitoring of five runners during a marathon using a wearable three‑lead ECG device (e-skin ECG; Xenoma Inc...

UNLABELLED: It has been reported that patients with moyamoya disease have a high prevalence of coronary artery disease. On the other hand, the pathology of coronary artery disease is not fully understood. We were able to evaluate vascular properties using optical coherence tomography in a case of acute myocardial infarction that occurred in a relatively young woman with moyamoya disease. Previous reports using intravascular ultrasound have shown that coronary artery lesions in patients with moyamoya disease are caused by fibrous cell proliferation...

UNLABELLED: We report a hybrid procedure of robotic-assisted coronary artery bypass grafting and transcatheter aortic valve-in-valve implantation for left main disease and prosthetic aortic valve stenosis. Robotic-assisted coronary artery bypass grafting using a left internal mammary artery graft was preferred to percutaneous coronary intervention because of the complex anatomy of the coronary lesion and concerns about dual antiplatelet therapy tolerance. This was followed by a valve-in-valve procedure five days later, allowing the patient to be discharged the next day...

UNLABELLED: Hypereosinophilic syndrome is a rare systemic condition characterized by eosinophil-mediated organ damage. Cardiac involvement is common and typically occurs in sequential stages. We present two cases that demonstrate these different stages and presentations of eosinophilia-mediated myocardial disease, where multimodality imaging was essential for the diagnosis. More importantly, they demonstrate, for the first time, the dissociation between the eosinophil count and patients' clinical evolution, suggesting the need for close follow up even after the eosinophilia has been controlled...

UNLABELLED: Cogan syndrome (CS) is a chronic inflammatory disorder primarily affecting young adults. It is characterized by interstitial keratitis, vestibuloauditory dysfunction, and, rarely, systemic vasculitis and aortitis. In this case report, we present a rare instance of a young male with anterior ST-elevation myocardial infarction in the context of aneurysmal coronary vessels and proximal occlusion of the left anterior descending artery. This case underscores the importance of recognizing cardiac risk factors in the setting of CS, as they can be life-threatening...

UNLABELLED: We report a case of a 63-year-old woman diagnosed with vascular Ehlers-Danlos syndrome (vEDS) who survived two prophylactic surgeries for the dilatation of a thoracoabdominal aortic aneurysm. She initially developed acute type B aortic dissection at the age of 44 years. Five years later, her dissected descending aorta was enlarged to 54 mm; thus, the descending aorta was replaced as the first surgery. Fortunately, the intra- and post-operative courses were uneventful...

UNLABELLED: We present an unusual case of ruptured sinus of Valsalva (RSOV) in the right atrium, progressive exertional dyspnea, occasional epigastric heaviness, and palpitations. The examination revealed high-pitch continuous murmur. On transthoracic echocardiography, there was a ~5-6 mm size RSOV of non-coronary sinus into right atrium, continuous turbulent flow, and unusual presentation of severe central aortic regurgitation jet with holodiastolic flow reversal seen in the descending aorta...

UNLABELLED: Ductus venosus stenting via a transumbilical approach for pulmonary venous obstruction in infracardiac total anomalous pulmonary venous connection has been described. In a 902-gram infant who was diagnosed with asplenia syndrome and infracardiac total anomalous pulmonary venous connection, ductus venosus stenting was attempted by a transumbilical approach. However, ductus venosus stenting was discontinued due to bleeding from the portal vein. The bleeding subsided in time spontaneously, and total anomalous pulmonary venous connection repair with pulmonary artery banding was performed on 21 days after birth...

UNLABELLED: Primary cardiac angiosarcoma is a high-grade aggressive tumor with a poor prognosis and low incidence. We describe a case of cardiac angiosarcoma, with pulmonary and adrenal metastases, diagnosed via fluorodeoxyglucose-positron emission tomography/computed tomography-guided adrenal biopsy. LEARNING OBJECTIVE: Cardiac angiosarcoma should be considered in a patient with a cardiac mass with no tumor cells in the pericardial fluid. Fluorodeoxyglucose-positron emission tomography/computed tomography could be useful in determining the biopsy site...

UNLABELLED: Patients with congenitally corrected transposition of the great arteries (ccTGA) often develop complete atrioventricular block and heart failure due to the abnormal disposition of atrioventricular node and disadvantage of systemic right ventricle. These issues are managed with a pacing system and a ventricular assist device (VAD), respectively. While technological advances offer new treatment strategies, the simultaneous deployment of a leadless pacemaker and a VAD in cases of ccTGA remains unexplored...

UNLABELLED: We report a case of a 45-year-old man presenting with tachycardia and palpitation. Echocardiography indicated severe tricuspid regurgitation. We suspected traumatic tricuspid damage due to high energy trauma in a motor vehicle accident 17 years earlier. He underwent a sternotomy, and his tricuspid valve was repaired with chordal reconstruction, indentation closure, and ring annuloplasty. The postoperative period was uneventful, and he was discharged 10 days after the operation...

UNLABELLED: Coronavirus disease 2019 (COVID-19) is associated with an increased risk of thromboembolic events. However, there are few reports on multiple thromboembolic events in young patients with COVID-19. Herein, we report a case of multiple visceral arterial embolisms secondary to acute myocardial infarction in a young patient with COVID-19. A 36-year-old male developed sudden chest pain after being diagnosed with COVID-19. Emergency coronary angiography revealed total occlusion of the right coronary artery, and the patient underwent a subsequent emergency percutaneous coronary intervention (PCI) which achieved successful recanalization...

UNLABELLED: Atrial amyloidosis is primarily caused by atrial natriuretic peptide (ANP) amyloid deposition. The main precursor protein causing cardiac amyloidosis is transthyretin (TTR), also known as TTR amyloid cardiomyopathy (ATTR-CM). A 73-year-old man, who presented with external dyspnea, was diagnosed with decompensated heart failure due to atrial fibrillation and severe mitral regurgitation. Left ventricular hypertrophy and elevated levels of high-sensitivity cardiac troponin T indicated cardiac amyloidosis...

UNLABELLED: Atrial tachyarrhythmias occurring after transcatheter atrial septal defect closure are not uncommon; however, those related to device stimulation are rare. Herein, a case involving a 24-year-old female, who developed drug-refractory atrial tachycardia during the early postoperative period, is reported. The results of electroanatomical mapping could eventually be obtained from both atria. They revealed a focal pattern, and the earliest site was located on the left atrial side of the superior atrial septum, between the left and right atrial discs of the device...

UNLABELLED: Herein, we report a case of myocarditis in a 27-year-old male with long-term follow-up using longitudinal peak systolic strain (LPSS) measurements with transthoracic echocardiography (TTE) and late gadolinium enhancement (LGE) in cardiovascular magnetic resonance imaging (CMR). On admission, a predominant decrease was observed in the LPSS in the posterolateral segments of the TTE. After a period of two weeks, the values of the LPSS observed in the posterolateral segments were still slightly reduced, which is consistent with the LGE results in CMR...

UNLABELLED: Giant cell myocarditis (GCM) is a potentially lethal subtype of myocarditis. Herein, we report a case of a 22-year-old woman with GCM who was successfully treated with prednisolone monotherapy. The patient had a fever and shortness of breath and was referred to our hospital. Laboratory test results revealed elevated troponin I levels. Cardiac magnetic resonance (CMR) showed high intensity in the inferoseptal segment of the left ventricle on T2-weighted short tau inversion recovery imaging without late gadolinium enhancement (LGE), suggesting predominant edema rather than necrosis...
