Successful hybrid repair of a giant coronary artery aneurysm after previous coronary artery bypass grafting.

Unlabelled: A 64-year-old woman had undergone coronary artery bypass grafting (CABG) for right coronary occlusion and the Dor procedure for a left ventricular apex aneurysm 10 years previously. A follow-up computed tomography scan showed the evolution of a giant coronary artery aneurysm (CAA) located on the proximal left circumflex artery (CX). It also revealed a previous saphenous vein graft (SVG) that was patent and located on the midline.

[Open Surgery after Zone 0 Debranch Thoracic Endovascular Aortic Repair with Fenestrated Stent Graft:Report of a Case].

Thoracic endovascular aortic repair (TEVAR) has been widely used in recent years as a treatment for thoracic aortic aneurysm, but open surgery may be required for various complications that cannot be controlled by endovascular treatment alone. It is often a more challenging operation. A 78-year-old man underwent two debranch TEVAR (zone 1) for thoracic aortic aneurysm eight years before, and he received TEVAR (zone 0) again with the Najuta stent graft for re-expansion of aneurysm due to typeⅠa endoleak two years before.

Recurrent nonbacterial thrombotic endocarditis the day after mitral valve replacement.

Nonbacterial thrombotic endocarditis (NBTE) is relatively rare, with an identification rate of 1.6% at autopsy, and is associated with malignancy and systemic lupus erythematosus. Further, bioprosthetic valve NBTE is extremely rare, with only a few reports in the literature.

Right ventricular outflow obstruction with squamous cell carcinoma of unknown origin.

A 60-year-old man was referred to our hospital because of chest tightness. CT scans showed no specific findings except a right ventricular (RV) mass. Echocardiogram revealed that the large cardiac mass was compressing the right ventricular outflow tract, and the patient thus underwent an emergency operation.

[Aorta-left Main Trunk Interposition for Adult Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery Using a Prosthetic Graft;Report of a Case].

A 70-year-old woman with back pain was diagnosed with adult anomalous origin of the left coronary artery from the pulmonary artery [Bland-White-Garland (BWG) syndrome]. Preoperative transthoracic echocardiography showed diffuse hypokinesia of the left ventricle and mild mitral valve regurgitation. Coronary angiography revealed dilatation of both coronary arteries, but no aneurysms.

Distinct effects of alcohol consumption and smoking on genetic alterations in head and neck carcinoma.

Background: Tobacco and alcohol consumption are risk factors for head and neck squamous cell carcinoma (HNSCC). Recently, whole-exome sequencing clarified that smoking increased TP53 and other mutations in HNSCC; however, the effects of alcohol consumption on these genetic alterations remain unknown. We explored the association between alcohol consumption and somatic copy-number alterations (SCNAs) across the whole genome in human papillomavirus (HPV)-negative HNSCCs, and compared with the effects of smoking on genetic alterations.
