Congenital bicuspid aortic valve is a risk factor of aortic dissection, but the case is rare in Japan. Several reports described ascending aortic aneurysm after aortic valve replacement. In these reports, most of aneurysms were false aneurysm, but the cases of ascending aortic dissection were rare. In this case, dissecting aneurysm of the ascending aorta occurred 4 years after aortic valve replacement, which was performed with mechanical prosthesis because of infective endocarditis, and it was repaired successfully by the modified Cabrol's method. This case was congenital bicuspid aortic valve, and had already been complicated with moderate aortic dilatation in the ascending aorta. In patients of congenital bicuspid aortic valve with aortic dilatation, consideration of complete replacement of the ascending aorta with aortic valve replacement is important.

Propionibacterium acnes rarely causes systemic disease. Few cases of P. acnes endocarditis have been reported. This report describes a 63-year-old man who presented with severe congestive heart failure. He had prosthetic valve endocarditis which resulted in severe acute aortic insufficiency. During surgery he was found to have complete disruption of the aorta and left ventricle with a false aneurysm encompassing the circumference of the aortic annulus. Cultures of the valve grew P. acnes. Thus, although P. acnes is a rare cause of endocarditis, it may pursue a very aggressive course, especially in the setting of a prosthetic valve.

Bentall's technique for repair of annuloaortic ectasia has been associated with postoperative bleeding and with false aneurysms at the anastomotic site between the coronary orifices and valve-containing graft. To reduce the incidence of these complications, we modified the Bentall procedure, using a simplified technique to implant the graft and to create a fistula between the closed perigraft space and right atrium to control bleeding. A continuous suture of monofilament polypropylene was used to implant the prosthetic valve ring and to anastomose the coronary orifices to the Dacron fabric. In some instances, a brief period of hypothermic circulatory arrest was needed to perform the distal aortic anastomosis. Among 562 patients undergoing operation for aneurysm of the ascending aorta between January 1, 1980, and February 28, 1990, 280 underwent graft replacement with a valve-containing composite conduit. Most (82%) had annuloaortic ectasia. In 267, we performed a classic Bentall procedure with direct anastomosis between the coronary orifices and fabric graft. The remaining 13 patients underwent other procedures for coronary connection. Early mortality was 5.0%. Reoperation for bleeding was needed in 13.2% of patients who underwent operation before we used the right atrial fistula technique and in 4.4% after we began to use the technique (p = 0.044). Actuarial survival was 71% at 5 years and 65% at 7 years. For hospital survivors, it was 76% at 5 years and 70% at 7 years. During follow-up, only 9 patients have required reoperation. A false aneurysm at the coronary anastomosis, which was associated with prosthetic valve endocarditis, developed in 1 patient. No permanent fistulas have developed.(ABSTRACT TRUNCATED AT 250 WORDS)

Two cases of left ventricular (LV) pseudoaneurysm following mitral valve replacement (MVR) are presented. In one patient the false aneurysm developed after an initially successful correction of intraoperative left ventricular wall rupture while the other case resulted from an apparently uncomplicated MVR performed because of staphylococcal endocarditis. Both cases were detected by combined 2-dimensional and Doppler echocardiography. The operative treatment was similar in both patients. After extirpation of the old prosthesis, the orifice of the pseudoaneurysm was closed from inside the heart, either with a Dacron patch or using interrupted sutures supported by a teflon pledget. One of the patients died one month postoperatively but the other one recovered and is clinically well 6 months after repair. She has, however, a residual communication between the LV and the pseudoaneurysm.

Four patients with infective endocarditis were examined by digital subtraction angiography immediately before operation. In three a root abscess was suspected and the remaining patient was believed to have a false aneurysm at an infected aortic cannulation site. In all the cases digital subtraction angiography showed the structure in several projections and confirmed the presence of a cavity. Subsequent operation confirmed the site and nature of the lesions.

An 11-year-old child developed prosthetic valve endocarditis with associated infection of the prosthetic and pericardial patches 6 months following an aortoventriculoplasty. Angiography revealed an associated false aneurysm which communicated with both the ascending aorta and the right ventricular outflow tract. This report discusses the surgical management of this patient.

A 32-year-old man was admitted with an intracerebral hematoma and subsequently with bilateral femoral emboli five months after aortic valve replacement. Blood cultures for bacteria and fungi were negative but microscopy of the embolus revealed Aspergillus fumigatus. At operation a large false aneurysm of the ascending aorta and vegetations on the prosthetic aortic valve were found. Aspergillus endocarditis is diagnosed antemortem in only 23% of fatal aortic aneurysms: blood cultures are positive in only 8%. Clinically a large vessel embolus is characteristic, being present in 83% and microscopy and culture of such an embolus if present are vital investigations.

Peripheral aneurysms of the leg are rare, and nearly always involve the popliteal artery. We describe the unusual presentation of a swollen leg caused by a large false aneurysm of a branch of the posterior tibial artery. This developed in the absence of either a history of trauma, local infection or infective endocarditis.

An eight-year-old boy with supravalvular pulmonic stenosis, supravalvular aortic stenosis, and ventricular septal defect developed Staphylococcus aureus endocarditis. The infection was complicated by formation of a false aneurysm of the right ventricular outflow tract, which was demonstrated by contrast echocardiogram. Surgical treatment was successful. This is a unique case of false aneurysm of the outflow tract of the right ventricle, because it is secondary to endocarditis without known previous trauma to the right ventricular wall.

Pseudoaneurysms of the ascending aorta are relatively uncommon compared with those evolving from the left ventricle. In a young man with endocarditis of the aortic valve who developed a pseudoaneurysm arising from the ascending aorta, the diagnosis was established with the pulsed Doppler technique and cross sectional echocardiography by passing the Doppler sample from the aorta through the neck of the false aneurysm into the large pseudoaneurysm. Aortic root angiography showed this connexion to be a small fistula between the aorta and right atrium. Necropsy findings confirmed the diagnosis.
