Right Ventricular Metastasis of Ewing Sarcoma Treated Through Surgical Resection.

A 27-year-old man diagnosed with right ventricular metastasis of Ewing sarcoma was referred to our institution. We surgically resected the metastatic tumor to prevent sudden death and reconstructed the right ventricle and tricuspid valve. He has survived for 1 year postoperatively without recurrence.

Validity of direct bilateral axillary arterial cannulation in emergency surgery for acute type A aortic dissection.

Background And Aim Of The Study: To assess the validity and long-term outcomes of direct bilateral axillary arterial cannulation for acute type A aortic dissection.

Methods: Between 2003 and 2020, 208 consecutive patients with acute type A aortic dissection underwent emergency surgical repair. Cardiopulmonary bypass was attempted to establish direct bilateral axillary arterial cannulation and bicaval drainage.

[Subcutaneous Bronchogenic Cyst in the Anterior Chest Diagnosed before Coronary Artery Bypass Grafting:Report of a Case].

A 65-year-old woman was transported to our hospital by ambulance because of severe dyspnea. She had had a subcutaneous tumor on her anterior chest since her childhood. Coronary angiography revealed three vessel disease with significant stenosis in the left main trunk.

Perivascular Adipose Tissue Is a Major Source of Nitric Oxide in Saphenous Vein Grafts Harvested via the No-Touch Technique.

Background Saphenous vein grafts (SVGs) are broadly used in coronary artery bypass grafting despite their inferior patency compared with arterial grafts. Recently, the no-touch technique (NT), in which an SVG is harvested with a pedicle of perivascular adipose tissue (PVAT) without conduit distension, was shown to improve long-term patency compared with conventional preparation (CV), wherein outer tissue is removed with distension. The NT was also reportedly associated with reduced atherosclerosis.

Preoperative evaluation of aortic calcification by computed tomography in thoracic aortic disease.

Background: Computed tomography (CT) is a useful tool for the identification of calcified lesions in the aorta. However, no quantitative evaluation has been established to assess the applicability of simple anastomosis preoperatively. We conducted this retrospective study to establish a reference range of maximal CT attenuation values for application of simple anastomosis.

Huge Primary Cardiac Malignant Lymphoma in the Left Ventricle.

A 67-year-old man presented at the hospital with worsening exertional dyspnea. Echocardiography showed a tumor in the left ventricle (approximately 35 × 48 mm) that protruded into the left atrium and left ventricular outflow tract during systole. These findings suggested a high risk of sudden death resulting from aortic valve obstruction or tumor embolism.
