Two patients with polytetrafluoroethylene (PTFE) grafts developed mycotic aneurysms at the suture lines. Both patients had chronic illnesses and recurrent infections. Attempts to surgically treat these aneurysms were unsuccessful. Infections involving PTFE grafts used in the management of children with congenital heart disease have not been reported. Problems related to ...
Duncan J M - - 1983
Mycotic aneurysms were first described as the result of nonsyphilitic bacterial infection of the arterial wall. They were often caused by septic emboli from bacterial endocarditis and were much more common prior to the era of antibiotics. Although the aorta is most often affected, such aneurysms may arise in any ...
Seabold J E - - 1983
The diagnosis of mycotic aneurysm is often elusive, since the patient frequently has signs and symptoms of sepsis only. A patient with a clinically occult mycotic aneurysm was assessed by the combined use of indium-111 leukocyte scintigraphy and computed tomography. While neither study was diagnostic by itself, the combined information ...
Humphrey R W - - 1983
A case of salmonella infrarenal aortic aneurysm that ruptured and was treated with staged operative procedures and a highly effective antibiotic is reported and analyzed. An emergency situation with a ruptured abdominal aortic aneurysm required prompt surgical intervention with an aortobifemoral graft insertion. In the immediate postoperative period it was ...
Ho S Y - - 1983
Two patients, an adult and a baby, with an aneurysm of the coronary sinus are described. This unusual anomaly was detected in the baby during angiographic investigations for congenital heart disease. The aneurysm was an unexpected postmortem finding in the adult. Although the adult died suddenly, there was no evidence ...
Revuelta J M - - 1983
Right ventricular outflow tract (RVOT) reconstruction with a new composite pericardial monocusp patch incorporating a sinus of Valsalva was performed in 7 patients. There was one hospital death. Follow-up ranged from 20 to 52 months (mean 25.4 months, cumulatively 206 patient months). Four patients have been recatheterized at an average ...
Johansen K - - 1983
Mycotic aneurysms are uncommon but not rare lesions with potential for catastrophic hemorrhage or sepsis. They have been ascribed to bacterial endocarditis and, when present in the aorta, were termed "inevitably fatal" as recently as 1967. A 15-year review of the English-language literature on mycotic aneurysms showed that arterial trauma, ...
Przybojewski J Z - - 1983
A young man had a congenital sinus of Valsalva aneurysm originating from the right coronary sinus, complicated by fistulas draining into both right atrium and right ventricle, as well as a congenitally abnormal aortic valve with mild aortic insufficiency. His dramatic clinical presentation, with the sudden appearance of severe biventricular ...
Henze A - - 1983
Ruptured aneurysms of the aortic sinuses of Valsalva have been a surgical rarity at the Karolinska Hospital. Only nine such cases were operated on over a 13-year period (1968-1971). All nine aneurysms were of congenital type. They originated in the right coronary or the non-coronary sinus and drained into the ...
Palmer P - - 1982
Sudden death in a 21 year old Papuan female was found to be due to a ruptured mycotic aneurysm of the right coronary artery. Caseous mediastinal glands were present but without other evidence of tuberculosis. As the reaction observed in the walls of the aneurysm was granulomatous, it is probably ...
Rehr R B - - 1982
Non-penetrating chest trauma commonly causes a wide variety of cardiac injuries. Disruption of the aortic valve with resultant aortic regurgitation is not uncommon; conversely, a sinus of Valsalva-right atrial fistula, in the absence of a congenital sinus of Valsalva aneurysm, has been reported only once previously. This report describes the ...
Fernando S S - - 1982
A 56-year-old Caucasian male, with no obvious immune deficit or systemic disease, presented with unilateral loss of vision due to A. fumigatus infection involving the right optic nerve. There was no proptosis. Despite fungal chemotherapy he developed central nervous system involvement with mycotic arteritis of the branches of the right ...
Yarnoz M D - - 1982
The case of patient with unruptured sinus of Valsalva aneurysm with absence of the intervalvular lamina fibrosa is presented. The association of Valsalva aneurysm and aortic subvalvular defects has been explained as a deficiency of elastic tissue at the aortic root or maldevelopment of the fibrous trigone. Valvular aortic insufficiency ...
Keren A - - 1982
Origin of both coronary arteries from the same sinus of Valsalva was found in two patients. In one patient the right coronary artery opened from the left sinus of Valsalva, coursed between the pulmonary artery and aorta, disclosed a 95% obstruction in its proximal third with good runoff. The portion ...
Noble R C - - 1981
A man with stenosis of the aortic valve acquired endocarditis after abdominal surgery. Klebsiella pneumoniae and Acinetobacter calcoaceticus were cultured from his blood. The blood cultures remained positive despite intravenous gentamicin and cephalothin to which the organisms were sensitive in vitro. Ultimately, the blood was sterilized by a combination of ...
Yokoi K - - 1981
Pulsed Doppler echocardiography (PDE) was performed on two cases with ruptured aneurysm of the right sinus of Valsalva into the right ventricle. PDE revealed a wide band pattern throughout the cardiac cycle when the sample volume was placed within the aneurysm. In the right ventricle below the aneurysm, a continuous ...
Engel P J - - 1981
A case is reported in which a congenital aneurysm of the right coronary sinus of Valsalva ruptured and dissected into the interventricular septum. M-mode and cross-sectional echocardiographic examination allowed accurate preoperative assessment of the pathologic anatomy, which was confirmed by angiography, surgery and autopsy. Dissection of the interventricular septum by ...
Fujinaga Y - - 1981
A case of common iliac mycotic aneurysm that presumably developed secondary to Klebsiella endocarditis was described. Recently, reports on gram negative septicemia and endocarditis have been on the increase. However, mycotic aneurysms secondary to bacterial endocarditis and particularly to Klebsiella endocarditis are rare. Inadequately treated serious gram negative septicemias have ...
DuBrow R A - - 1981
Three cases of mycotic aneurysm of the renal artery are presented, all of which manifested similar findings on excretory urography and renal arteriography: small intrarenal aneurysm with distal occlusion, corresponding nephrographic defect or defects on urography and arteriography, and opacification of a normal collecting system. To the authors' knowledge these ...
Nakamura K - - 1981
The M-mode and two dimensional echocardiographic features are described of a patient with rupture of a sinus of Valsalva aneurysm into the right atrium.

Plotkin G R - - 1981
Infections of the cardiovascular system, besides involving both natural and prosthetic heart valves, vascular grafts, and indwelling venous and arterial cannulas, may cause mycotic aneurysms. The latter frequently complicate endocarditis; however, they may occur as isolated phenomena. Enterobacteriaceae are uncommon etiologic agents in vascular infections; however, a patient is reported ...
Thevenet A - - 1981
Surgical repair of the diffuse form of supravalvular aortic stenosis, (tubular hypoplasia of ascending aorta) is a difficult problem because complete relief of the pressure gradient is not achieved by the insertion of a prosthetic graft across the non coronary sinus of Valsalva. An alternative is to use a left ...
Incarvito J - - 1981
A 26-year-old male with fungal aortic endocarditis is presented in whom unique M-mode and two-dimensional echocardiographic findings permitted a diagnosis of mycotic aneurysm of right sinus of Valsalva and ventricular septal abscess preoperatively. The aneurysm was excised, and the affected aortic and tricuspid valves were replaced with valve prostheses.
Haaz W S - - 1980
Fluttering of the right side of the interventricular septum noted on M-mode echocardiography in association with a bulging of the right sinus of Valsalva detected by two-dimensional echocardiography were present in a patient. These two echocardiographic findings should alert the clinician to a diagnosis of a ruptured sinus of Valsalva ...
Johansen K - - 1980
A 55-year-old man had excision of two mycotic infrarenal aortic aneurysms five months after a severe, prolonged bacteremia. At the time of aortic surgery he was asymptomatic and had sterile blood cultures, and the resected aortic specimen demonstrated no organism on bacteriologic or histologic examination. Though these lesions may sporadically ...
McGee M B - - 1980
A 53-year-old man with a kidney transplant was hospitalized because of back pain, fever, and an enlarging heart size. Cultures of blood and stool yielded Salmonella enteritidis (group D, serotype enteritidis). Despite appropriate antibiotic therapy, the patient died of cardiac arrest on the seventh hospital day. Autopsy revealed a ruptured ...
Shulman R - - 1980
A 2-cm aneurysm of the right sinus of Valsalva was documented in a patient with a prosthetic aortic valve. The M-mode findings differed from prior reports and mimicked those of aortic root dissection or a catheter placed in the right ventricular outflow tract. Two-dimensional echocardiograms readily distinguished the aneurysm of ...
Kasper W - - 1980
The echocardiographic features of ruptured sinus of valsalva aneurysm were described in a 32-year-old man. The diagnosis was established deductively using the precordial, subxiphoidal and suprasternal approach. Despite careful scanning no discontinuity between the anterior aortic wall and the interventricular septum could be observed, thus demonstrating directly the perforated part ...
Chen J J - - 1980
Clinical features of 19 cases with congenital aneurysm of the right sinus of Valsalva rupturing into the right ventricular outflow region (Type 1) were analysed in relation to their pathoanatomic lesions and hemodynamic alterations. Sixteen cases were operated with one surgical death. All were catheterized together with ascending aortographic study. ...
Monson R C RC - - 1980
Carotid aneurysms are an extremely rare entity; mycotic carotid aneurysms are even more uncommon. Most articles in the past have advocated ligation as treatment of mycotic carotid aneurysms due to the dangers of graft placement in an infected field. Unfortunately, stroke occurs in many patients so treated. As the cerebral ...
Castaneda-Zuniga W R - - 1980
The radiographic and pathologic features of 13 cases of mycotic aneurysm of the aorta were reviewed retrospectively. In four cases the mycotic aneurysm was associated with bacterial endocarditis following aortic valve replacement, and in nine cases it was associated with spontaneous bacterial endocarditis. Postmortem examination revealed that the mycotic aneurysm ...
van Asperen de Boer F R - - 1980
A case is presented in which after removal of an infected renal allograft because of rejection, mycotic bleeding from the iliac artery could not be treated by ligature of the artery in view of the resulting ischaemia ofthe leg as demonstrated by a trial occlusion. A successful solution to this ...
Martínez A J - - 1980
Primary amebic meningoencephalitis and granulomatous amebic encephalitis are well recognized clinicopathological entities caused by free-living amebas. Associated arteritis and "mycotic aneurysms" with infiltration of intracranial arteries by lymphocytes, amebic trophozoites and cysts have not been previously reported. A 26-month-old girl had a 3-week history of encephalitis, characterized, initially, by vomiting ...
Oberhänsli I - - 1979
We report the case of an arteriovenous fistula connecting the aorta to the right atrium, due to a ruptured aneurysm of the left sinus of Valsalva. Clinical, echocardiographic, and angiographic aspects of this unusual lesion are discussed and correlated. Emphasis is put on the diagnostic value of the echocardiogram; a ...
Lambert M J MJ - - 1979
A painful, pulsatile neck mass with associated fever should suggest the presence of a mycotic carotid artery aneurysm. Diagnosis can be confirmed from angiograms. Broad spectrum antibiotics are indicated, and an operation should be performed promptly. The lack of tissue planes uninvolved by infection will almost always prevent vascular reconstruction. ...
DeSa'Neto A - - 1979
A sinus of Valsalva-right atrial fistula secondary to nonpenetrating chest trauma is described. Echocardiogrpahy demonstrated diastolic fluttering of the anterior tricuspid valve, suggesting a left-to-right shunt at the level of the right atrium. External jugular venous pulse tracings revealed large alpha waves and attenuation of the y descent. Cardiac catheterization ...
Raizes G S - - 1979
A patient with unruptured aneurysm of the sinus of Valsalva presented because of ventricular tachycardia refractory to medical therapy. The underlying problem was not suspected until cardiac catheterization. Once the aneurysm was repaired, the tachycardia was abolished; the patient required no antiarrhythmic drugs. Two points are emphasized: First, cardiac catheterization ...
Ee B - - 1979
A mycotic aneurysm is an uncommon, but serious, complication of infective endocarditis, occurring as a result of an infected embolus being lodged in the vasa vasorum or lumen of an artery. Involvement of the ulnar artery is rare, but its peripheral location renders its diagnosis more simple. A case of ...
Allard J R - - 1979
A technique for producing valvar aortic stenosis is described. The noncoronary sinus of Valsalva is plicated externally at a level proximal to the origin of the coronary arteries. The major intraoperative problems are hemorrhage, acute left ventricular failure, and heart block, all of which can be avoided. The survival rate ...
Sher R F - - 1979
This case demonstrates that complications develop with aneurysm of the sinus of Valsalva. The aneurysm is diagnosed almost exclusively only after rupture. We feel that echocardiography provides a convenient means to follow cases of suspected aneurysms. A change in aortic root size may indicate imminent rupture. Fluttering of the anterior ...
Schneider J A - - 1979
Sudden and usually fatal rupture is a common complication of postcoarctation mycotic aneurysms. Prompt operative treatment is always indicated, and can be performed using one of three techniques depending on the adequacy of the collateral circulation and the presence or absence of active bacterial infection. Renal dysfunction commonly is associated ...
Kaufman S L - - 1978
Nine patients examined by arteriography were shown to have mycotic aneurysms involving the thoracic aorta, subclavian artery, renal artery, middle cerebral artery, hepatic artery, and splenic artery. Patients presented with sepsis, chest pain, mediastinal mass, headache, hypertension, and intraperitoneal bleeding. Etiologic factors included endocarditis, septicemia, drug abuse, and poorly controlled ...
Yoshida S - - 1978
A rare case of sinus of Valsalva aneurysm ruptured into the left ventricle was reported. The echocardiogram was suggestive of the diagnosis. The abnormal echo extended from the aortic root to the left ventricular cavity in diastole and disappeared in systole. Discussion was made on the etiology and differential diagnosis.
Yakierevitch V - - 1978
The clinical and pathological features in three cases of false aneurysm of the left ventricle are reported. In two instances the condition developed after myocardial infarction, and in the third case a mycotic pseudoaneurysm developed after purulent pericarditis. All three patients were in intractable heart failure before urgent operation. The ...
Feldman R L - - 1978
A patient who had endocarditis on a prosthetic aortic valve and who had undergone two aortic valvular replacements developed classic angina pectoris. Cardiac catheterization revealed an aneurysm of the left sinus of Valsalva, which constricted a proximal segment of the left circumflex coronary artery during systole. This type of dynamic ...
Foote R A - - 1978
In order to study the effects of septic embolism on the brain, silicone rubber emboli of various types were injected into the carotid arteries of 35 dogs. Pathologic and angiographic studies were performed to assess the resultant arterial and parenchymal lesions. Pure silicone rubber emboli (14 dogs) produced occasional intra-arterial ...
