ABSTRACT
An 82-year-old man was referred to our hospital because of fever and disequilibrium. Brain magnetic resonance imaging showed acute multiple cerebral infarctions with multiple small intracerebral hemorrhages. The laboratory tests revealed an elevated inflammatory response, and two separate sets of blood cultures were positive for Streptococcus oralis. Transesophageal echocardiography revealed a single site of vegetation (13×11 mm) of the mitral anterior annulus. The vegetation apparently did not involve the intervalvular fibrous body. Moderate mitral regurgitation and mild to moderate aortic regurgitation were detected. Early surgical intervention was considered, but there was a high risk of operative mortality. We thus initially performed only medical treatment. Transesophageal echocardiography was again performed 12 days after his admission and revealed vegetation of the mitral anterior annulus progressing to the aortic annulus via the intervalvular fibrous body. It seemed to be difficult to control this progressive infective endocarditis with medical treatment. We therefore performed a semi-urgent operation. With an incision into the right-side left atrium, we identified the vegetation of the center of the mitral anterior leaflet progressing to the mitral anterior annulus. Subsequently, we added an aortotomy with Manouguian’s incision. We were able to remove all vegetation that was present in the aortic annulus, intervalvular fibrous body, and mitral annulus with a Commando operation. Finally, we performed double valve replacement with reconstruction of the intervalvular fibrous body and other lost cardiac structures using one boat-shaped bovine pericardial patch. He was discharged to home 34 days after surgery with no neurological complications and no recurrence of infective endocarditis. He also had no recurrence of infective endocarditis and no paravalvular leakage on either prosthetic valve at one year after the surgery.
ABSTRACT
Surgery for a shaggy aortic aneurysm requires a meticulous strategy to prevent embolic complications since the complications are associated with longer length of hospital stay and higher mortality. However, until now, there are no established treatment options to prevent embolic complications. We report a case of a 75-year-old man with a descending aortic aneurysm and a shaggy aorta who underwent thoracic endovascular aortic repair (TEVAR) with major branch artery protection. During the procedure, we placed balloon catheters in the left subclavian and left common iliac arteries, a filter device in the superior mesenteric artery, and a sheath at the ostium of the right common iliac artery. The patient did not develop embolic or other complications and was discharged on the eighth postoperative day. Our strategy of using the balloon occlusion technique and filter placement at the major vessels effectively prevented embolic complications during TEVAR for a shaggy aorta.
ABSTRACT
<p>An 84-year-old woman with severe aortic stenosis (AS) and coronary artery disease (CAD) was admitted repeatedly with syncope and heart failure. Due to her comorbidities, concomitant transapical transcatheter aortic valve replacement (TAVR) and off-pump coronary artery bypass grafting (OPCAB) were performed. She did well postoperatively. CAD is often found concurrently in patients presenting with severe symptomatic AS. Concomitant TAVR and OPCAB is considered as a less invasive and more feasible treatment option in high-risk patients.</p>
