A surgically salvaged case: emergency Root-Commando procedure for infective endocarditis and chronic dissecting aneurysm of the sinus of Valsalva.

The Commando procedure for infective endocarditis is a high-risk intervention. However, infective endocarditis involving the intervalvular fibrosa is fatal in the absence of surgery. A 41-year-old man with no medical history visited a doctor with chest pain and dyspnoea. Ascending aortic dissection and vegetation on the mitral valve were noted on echocardiography, so he was transferred to our hospital. The diagnosis was dissecting aneurysm of the sinus of Valsalva and acute heart failure due to aortic regurgitation, mitral regurgitation and infective endocarditis. We decided on emergency surgery. Intraoperatively, we confirmed abscess extending to the left atrial roof and destruction of the intervalvular fibrosa, so we performed the Root-Commando procedure. The patient was saved and discharged 47 days after transfer to our hospital through the reoperation on postoperative day 30.

[Left Hemothorax without Pericardial Effusion due to Pacing Lead Penetration Through Right Ventricular Wall:Report of a Case].

Cardiac perforation by a pacemaker lead that causes left hemothorax without pericardial effusion is rare and life threatening. So, we report a surgically salvaged case. A 55-year-old man underwent insertion of adevice for cardiac resynchronization therapy and defibrillation. On the second postoperative day, the patient fell into shock state after defecation. Electrocardiogram showed pacing failure and computed tomography (CT) showed left hemothorax without pericardial effusion. A drainage tube was placed in the left pleural cavity, and bleeding was massive and continuous. We then performed emergency surgery for suspected cardiac perforation by the pacemaker lead. The right ventricular lead had penetrated the ventricle, which was surgically repaired.

Intraoperative angiography for visceral arteries originating from false lumen.

A 70-year-old man had an acute type B aortic dissection 9 years before his admission. The last enhanced computed tomography that was performed revealed an aneurysm that extended from the ascending aorta to the aortic arch, associated with a chronic aortic dissection, which extended from the aortic arch to the left external iliac artery. His visceral arteries originated from the false lumen. We performed a total arch replacement with a frozen elephant trunk in the hybrid operating room. Immediately after the circulatory arrest termination, using intraoperative angiography, we verified that the blood supply to the visceral arteries was patent.

Thoracic endovascular aortic repair of a ruptured acute type B aortic dissection presenting with right hemothorax: a case report and review of the literature.

Ruptured acute type B aortic dissection is a life-threatening condition with a high mortality rate. Right hemothorax secondary to this condition is extremely rare. Herein, we report a successful treatment of a ruptured acute type B aortic dissection via thoracic endovascular aortic repair in a 45-year-old man who initially presented with right hemothorax. Contrast-enhanced computed tomography confirmed massive right hemothorax and acute type B aortic dissection in which the primary entry was located just below the left subclavian artery. Moreover, a possible rupture site in the descending aorta at the level of Th6 was identified. We then performed an endovascular aortic repair with left subclavian artery open surgical debranching. His postoperative course was uneventful. The patient did not have any complications at a 6-month follow-up.
