A 71-year-old woman with active aortic prosthetic endocarditis due to Methicillin-resistant Staphylococcus epidermidis (MRSE) and subannular mycotic aneurysm and paravalvular leakage and acute mitral regurgitation underwent emergent surgical treatment. The mycotic aneurysm was closed using a prosthetic patch after surgical debridement. Re-aortic valve replacement with a 21-mm Hancock II prosthesis was performed at the paraannular position by utilizing the patch. Mitral valve was also replaced with a 27-mm Hancock II prosthesis. Antibiotic therapy was provided by vancomycin combined with rifampicin and gentamicin. The following regimen was given, vancomycin 1 g i.v. q12h for 6 weeks plus gentamicin 80 mg/day i.v. for 4 weeks plus rifampicin 450 mg/day orally for 6 weeks. Vancomycin and gentamicin doses were modified appropriately according to the monitored serum levels in the patient with renal failure. Postoperative course was uneventful. The patient is doing well 11 months after surgery and no recurrence of infection has been seen. We conclude that prompt surgical removal of the infected sources and appropriate antibiotic therapy based on the bacteriology may be the only curative treatment for uncontrolled infection at the active phase of MRSE prosthetic endocarditis.

We encountered a case of mitral stenosis, complicated with non-bacterial thrombotic endocarditis, that developed after percutaneous transvenous mitral commissurotomy (PTMC). A 71-year-old female Japanese patient had severe congestive heart failure and underwent PTMC for critical and severely calcified mitral stenosis. Four weeks later, the echocardiogram demonstrated a highly echoic protrusion in the postero-medial commissure of the mitral valve. There was little evidence of inflammation at that time. She had been anticoagulated adequately since she was admitted. The patient underwent replacement of the mitral valve. She did not show any evidence of systemic embolization. Microscopic evaluation showed only organized thrombus but no evidence of inflammation in the mitral valve. Silent development of non-bacterial thrombotic endocarditis after PTMC should be recognized as a rare but potentially lethal complication of PTMC.

A 71-year-old female was admitted with the complaints of dysarthria and right hemiparesis. CT scan revealed subarachnoid hemorrhage in the left cerebral sulcus. The first angiography was performed 3 days after the onset and left carotid angiography revealed a small aneurysm arising from the left middle cerebral artery. After 3 weeks of antibiotic therapy, the second angiography showed the aneurysm to be clearly enlarged, so it was resected. The patient complained of marked dysarthria a day after the operation and CT scan revealed a new infarction in the right frontal lobe. The third angiography showed an aneurysm arising from the right middle cerebral artery and the fact that two peripheral arteries of the aneurysm had disappeared 3 weeks after the first operation. The second operation was performed and a bacterial aneurysm was resected. The patient left the hospital without any neurological deficits. Septic embolism is the most important complication of infective endocarditis and it is usually presented with subarachnoid hemorrhage and intracerebral hemorrhage caused by ruptured bacterial aneurysms. In this case the septic embolism occurred two times. At each time cerebral ischemic attacks were presented. The reason why this case presented with ischemic symptoms was suspected to be that embolisms occurred at the trifurcation of the distal middle cerebral arteries. We were able to detect a bacterial aneurysm angiographically 3 days after the ischemic attack and we suspected that a bacterial aneurysm had been able to develop within 3 days after the septic embolism.

Prosthetic valve endocarditis with an extensive aortic root abscess usually has high mortality and morbidity. A 71-year-old male with an extended aortic root abscess following aortic valve replacement survived after full aortic root reconstruction with glutaraldehyde bovine pericardium, mitral valve replacement and full root replacement using stentless bioprosthesis. The patient is well without recurrence of infection, 18 months postoperatively. This procedure might be an alternative treatment for prosthetic valve endocarditis with an extended aortic root abscess.

The authors evaluated various clinical courses of ruptured infectious cerebral aneurysms associated with infective endocarditis in 4 patients. The first case: A 60-year-old male, who had a large hematoma resulting from rupture of a distal anterior cerebral artery aneurysm at the left frontal lobe co-existing with cerebral infarction at the right temporo-occipital lobe, with complications of renal and liver embolisms and pyogenic spondylitis, was treated with antibiotic therapy. However, he died of rupture of another newly formed aneurysm 29 days after onset. The second case: A 71-year-old female presented cerebral infarction in the right occipital lobe at onset. Two days later, abrupt occurrence of a large hematoma at the left parietal lobe led to deterioration of her consciousness. She underwent emergent evacuation of a large hematoma containing the infectious cerebral aneurysm proven histologically afterwards. The third patient: A 49-year-old female was suffered from a large hematoma and subdural hematoma accompanied distal posterior cerebral artery aneurysm at the right occipital lobe. She was operated by removal of the hematoma and the aneurysm proven as a bacterial infectious aneurysm. The fourth patient: A 71-year-old female had hemiplegia caused by a brain abscess and cerebral hemorrhage in the right temporal lobe and a distal middle cerebral artery aneurysm adjacent to the same region. Trapping of the aneurysm was undertaken and clinical course was uneventful. Attention needs to be paid to the various cerebrovascular condition arising from the bacterial embolus of infective endocarditis.

The diagnosis of fungal endocarditis requires a high index of clinical suspicion. Rarely, pacemaker implantation may be a risk factor for the development of fungal endocarditis. A 71-year-old man with a history of multiple transvenous pacemaker manipulations and fever of an uncertain source is described. A diagnosis of culture-negative pacemaker endocarditis was established only after repeat transthoracic echocardiography. Amphotericin B was instituted; however, the patient developed a cerebral infarct and died. Postmortem examination demonstrated Aspergillus fumigatus within a large pacemaker lead thrombus, tricuspid and aortic valve vegetations, and septic pulmonary and renal emboli. The present report describes the clinical and pathological features of a rare case of Aspergillus fumigatus pacemaker lead endocarditis and suggests that serial echocardiograms may be effective in the early detection of pacemaker lead vegetations. The diagnostic features and therapeutic management of pacemaker lead endocarditis are reviewed.

A 71-year-old woman, who had undergone mitral valve replacement procedure 2 years previously, presented with aortic and mitral prosthetic valve endocarditis. Preoperative examination demonstrated a wire-like structure coursing from the aortic bulb to the right carotid artery. The wire-like structure was removed during the mitral and aortic valve reoperation, and identified as an epicardial pacing wire, which was placed during the patients' first mitral valve operation. We suspect that the contaminated pacing wire migrated via the left atrium and left ventricle into the right carotid artery causing an infective endocarditis of the prosthetic mitral valve and the native aortic valve.

A 71-year-old high-risk fourth-time redo male patient was diagnosed with prosthetic valve endocarditis of both aortic and mitral valves, and subsequently required a re-operative aortic and mitral valve replacement. He was placed on cardiopulmonary bypass (CPB) and arrested with normothermic hyperkalemic all-blood cardioplegia (microplegia) containing adjunctive adenosine-lidocaine-magnesium (adenocaine); aerobic arrest was maintained with near-continuous retrograde low potassium (approximately 2 mEq/L) adenocaine microplegia. After 4 hours of arrest on CPB, the aortic valve was found to be incompetent and was resected. A root replacement was required utilizing a Medtronic Freestyle Root prosthesis. Four separate periods of cross-clamp were required during the course of the entire operation. The patient was on CPB for 9.8 hours with a total cross-clamp time of 7 hours, during which he received 72 liters of all-blood adenocaine microplegia. After a terminal "hot shot" with adenocaine microplegia and no added potassium, CPB was discontinued with no systemic hyperkalemia (5.1 mmol/L), no hemodilution (hematocrit, 24%), no balloon pump, no antiarrhythmic agents, and modest inotropic support. The patient was hemodynamically stable, was extubated in 12 hours, and was transferred out of the cardiac ICU after 48 hours with a subsequent uneventful recovery.

A 71-year-old man underwent implantation of a single-chamber system in 1988 for sinoatrial disease, which was then upgraded to dual-chamber 7 years later following recurrent syncope. He presented with pacemaker erosion but without clinical or laboratory evidence of infective endocarditis. The pacemaker system was uneventfully extracted 5 days later via a transfemoral approach using a needle-eye snare. A post-procedure trans-thoracic echocardiogram was performed, which demonstrated an echogenic structure in the right atrium-this was initially felt to be a retained fragment of pacing lead. A short-axis view of the tricuspid valve with a bright linear echo crossing is shown in Figure 1. However, a post-procedural chest X-ray confirmed the absence of any retained intra-cardiac lead. The reverberant cast-like structure noted is a heavily calcified fibrous sheath as the pacing leads were confirmed to be intact at the time of removal.

Successful surgical treatment of a case of infective endocarditis with embolism to a lower extremity artery is reported. A 71-year-old man was referred to our hospital for the treatment of infective endocarditis. Echocardiography showed a vegetation on the non-coronary cusp of the aortic valve measuring 19 mm in diameter. We planned surgical treatment, including aortic valve replacement, however, embolism of a lower extremity artery by the vegetation occurred during the waiting period for the operation. We removed the offending vegetation from the popliteal artery and replaced the peccant aortic valve with a prosthetic valve in separate operations. The postoperative course was uneventful and the patient was transferred to another hospital on the 33rd day after the valve replacement surgery.
