Cardiac injury accounts for less than 10 % of all traumas and it is a fatal condition associated with cardiac tamponade or massive haemothorax, which requires immediate intervention, such as resuscitative thoracotomy. However, in case of haemothorax without the findings suggestive of cardiac damage such as pericardial effusion, it is difficult to determine the complications of cardiac injury, because injury of the lung or intercostal arteries is usually considered first. We describe a rare case of left atrial appendage rupture with a right-sided massive haemothorax with slight cardiac effusion.

Open surgery for chronic type B aortic dissection has been shown to have considerable risks of cerebrovascular complications. Because retrograde perfusion is a potential cause of intraoperative cerebrovascular events, we report our transapical cannulation strategy for descending aorta replacement in chronic type B aortic dissection repair with circulatory arrest. This technique provides an easy and quick establishment of cardiopulmonary bypass by way of a left thoracotomy, and prevention of cerebrovascular event.

Although there are several mitral valve aneurysm reports, studies on aortic valve aneurysm are extremely rare. This paper describes an uncommon case of a large saccular aortic valve aneurysm associated with infective endocarditis. A 37-year-old man was hospitalized in our hospital with fever and dyspnea.

I report a hemorrhagic complication due to disseminated intravascular coagulation after thoracic endovascular aortic repair for a dissecting aortic aneurysm. A 74-year-old man underwent thoracic endovascular aortic repair and carotid-carotid artery bypass to close the primary entry site of the dissecting aortic aneurysm. Postoperatively, he developed a gradually expanding cervical hematoma.

Background And Aim Of The Study: Controversy exists regarding the optimal operative method or type of prosthesis for patients with a small aortic root. The aim of this retrospective study was to investigate the early and mid-term outcomes of standard aortic valve replacement (AVR) using 16 mm or 18 mm ATS Advanced Performance (AP) or 17 mm St. Jude Medical (SJM) Regent valves for a small aortic root.

Association of a right-sided aortic arch with an aberrant left subclavian artery is rare. We present a case of successful endovascular repair of a ruptured Kommerell diverticulum associated with a right-sided aortic arch and aberrant left subclavian artery. We treated a 47-year-old woman with a diagnosis of ruptured aberrant left subclavian artery with thoracic endovascular stent-grafts.

Background And Aim Of The Study: Mitral annular calcification (MAC) occurs mainly at the posterior half of the annulus, and is often seen in dialysis-dependent patients who have a high risk for cardiac surgery. A simple supra-annular prosthesis insertion ('half-and-half') technique was applied to five dialysis patients with extensive MAC to prevent catastrophic complications.

Methods: Five dialysis patients with extensive MAC underwent mitral valve replacement (MVR) using the 'half-and-half' technique.

Thrombin generation is considered unavoidable during cardiac surgery using cardiopulmonary bypass (CPB). We compared the effects of open and closed circuits on coagulation and fibrinolysis under identical conditions of priming volume, heparin-coating, and anticoagulation and transfusion protocols. Thirty coronary surgery patients were randomized to surgery using open circuits with open reservoirs and cardiotomy suction (open group, n=15) or closed circuits without either (closed group, n=15).

We report an uncommon case of thrombogenesis in the distal aortic arch after apicoaortic conduit (AAC) for severe aortic stenosis (AS). A 71-year-old woman underwent AAC with a bioprosthetic valve for severe AS because of heavy calcification of the ascending aorta. Although anticoagulant therapy with warfarin was performed, a postoperative computed tomographic (CT) scan revealed a thrombus in the distal aortic arch.
