Successful Surgical Intervention for Infected Mitral Endocarditis in a Patient Complicated with Multiple Cerebral Infarction and Hemorrhage / 日本心臓血管外科学会雑誌

The optimal timing of cardiac surgery for infective endocarditis in patients with severe brain complication remains unclear. We present here the successful surgical treatment of a case of infected mitral endocarditis with intractable heart failure, disseminated intravascular coagulation (DIC), and cerebral infarction with hemorrhage. A 37 year-old woman who received chemotherapy for breast cancer developed mitral infective endocarditis perhaps caused by infection of the implanted central venous access device and was referred to our hospital for an emergency operation. On admission, she had a mild fever and showed motor aphasia and right-sided hemiplegia. Brain CT scan findings revealed a cerebral infarction in the area of the left middle cerebral artery and a cerebral hemorrhage in the right occipital lobe. Echocardiography showed severe mitral regurgitation with huge mobile vegetation. Chest X-ray revealed severe pulmonary congestion and laboratory data showed DIC. After the mitral valve replacement with a bioprosthetic valve following complete excision of infected tissue, she was extubated on the first postoperative day with dramatic improvement of infectious signs and heart failure. Postoperative brain CT showed a new small brain hemorrhage, but no aggravation of the preoperative cerebral lesion. After she underwent surgical drainage for brain abscess on the 15th postoperative day, her postoperative course was uneventful. Even though this report is limited to a single case, only aggressive and prompt surgical intervention could relieve the intractable conditions in such a patient with extremely high risk.

Single-Stage Repair of Thoracic Aortic Aneurysm Associated with Aortic Stenosis and Pseudocoarctation by Means of the Clamshell Approach / 日本心臓血管外科学会雑誌

A 64-year old man was admitted to our hospital with a diagnosis of aortic stenosis. Pre-operative chest CT revealed pseudocoarctation of the aorta with a hypoplastic aortic arch, elongation and kinking of the aortic arch and proximal descending aorta. There was also a large aneurysm from the distal arch to descending aorta. We performed a single-stage repair of the aortic lesion from the ascending to the descending aorta with aortic valve replacement. For the surgical approach, transverse clamshell incision was applied safely. Concomitant aortic valve replacement in surgical repair of pseudocoarctation and thoracic aneurysm was rare, and clamshell incision seemed beneficial in such single-stage repair from the aortic root to the descending aorta.
