Between January 1992 and June 1994, 23 patients underwent surgery for aortic valve endocarditis at the Department of Cardiovascular Surgery of the University of Verona; a subgroup of 10 patients underwent aortic valve replacement with a porcine stentless valve (Biocor LTDA n = 8; Toronto SPV n = 2). There were 7 males and 3 females with a mean age of 56.3 years (range, 36 to 73 years). Eight patients had active endocarditis and two had healed endocarditis. Nine patients had native valve in endocarditis, the presence of a bicuspid aortic valve in 2, and 1 patient had recurrent prosthetic valve endocarditis (PVE), 7 of whom were in New York Heart Association (NYHA) Functional Class IV. The main indications for operation were congestive cardiac failure, active sepsis, and presence of large and mobile vegetations by echo and arrhythmias. There were no operative or late mortalities in this subgroup of patients. Short-term survival is 100% at a mean follow-up time of 11.2 months (range, 4 to 18 months), with no recurrent endocarditis or valve-related complications.

The congenital bicuspid aortic valve functions almost normally provided degeneration does not occur, but complications of infective endocarditis and calcification of the cusps with aging are indications for surgical intervention. We compared 22 cases with an incompetent bicuspid aortic valve (14 cases with stenosis and eight with regurgitation) with 96 cases of acquired tricuspid aortic valve (30 cases with stenosis and 66 with regurgitation) who were treated by aortic valve replacement (AVR) during the same period. Compared with the stenotic tricuspid aortic valve cases, the stenotic bicuspid aortic valve cases: 1) were older at AVR (59.3: 51.7 years, P < 0.05), 2) had a smaller diameter of preoperative valve orifice (6.9: 9.2 mm, P < 0.05), 3) had a smaller valve ring diameter (23.0: 24.3 mm, P < 0.05), 4) used artificial valves of almost identical size (22.0: 22.5), and 5) included no operative deaths (0: 10%). In contrast, compared with the tricuspid aortic valve cases with regurgitation, the bicuspid aortic valve cases with regurgitation: 1) were younger at AVR (39.5: 45.8 years), 2) had a higher incidence of infective endocarditis (62.5: 19.6%, P < 0.02) as a complication, and 3) showed a higher operative death rate (25.0: 6.1%), although this difference was not statistically significant. Suture repair of the incised portion of the aorta must be performed meticulously in patients with prominent poststenotic dilatation of the ascending aorta.

Little morphologic information is available on operatively excised pulmonic valves. The causes of pulmonic stenosis are limited to a few conditions: (1) rheumatic and (2) nonrheumatic (congenital, carcinoid, infective endocarditis). Congenital causes of pulmonic stenosis constitute well over 95% of these conditions. Congenital types of pulmonic stenosis include acommissural dome-shaped, dysplastic, and bicuspid. Rare acquired causes of pulmonic stenosis include carcinoid, rheumatic, and infective endocarditis. Of the acquired causes of pulmonic stenosis, carcinoid is the most common condition. In contrast, causes of pure pulmonic regurgitation are multiple. Two major categories of pure pulmonic regurgitation include (1) conditions associated with anatomically abnormal valve cusps (congenital, rheumatic, carcinoid, trauma, and infective endocarditis) and (2) conditions associated with anatomically normal cusps (elevated pulmonary artery systolic pressures, idiopathic dilated pulmonary trunk, and Marfan's syndrome).

Two cases of embolic infective endocarditis on bicuspid aortic valve are described. The trans-thoracic and trans-esophageal echocardiographic aspect could leave easily suppose the possibility of embolism. The prophylactic surgical treatment, during the active phase, also if the indication is debated, could have probably avoided the serious consequences of embolism.

From May 1990 to January 1994, 120 patients underwent aortic valve replacement with the use of the Biocor porcine aortic stentless heart valve (BPASHV). There were 83 male and 3 female patients. The age ranged from 11 seventy-six (76) years with a mean of 36. Eighty-five patients were under 40 years of age. Sixty-four patients underwent their first aortic valve replacement due to rheumatic heart disease, 30 because of prosthetic valve failure and of those: 20 were due to primary tissue failure and in 10 due to prosthetic endocarditis, native aortic bicuspid valve in 11 and senile calcificant aortic valve disease in four. Thirty-three patients had aortic annular related pathology. Their preoperative functional class revealed 61 patients in class III and 59 in class IV. The longest follow-up in this aortic group was 42 months with a mean of 26. The surgical technique used rendered consistent and reproducible results. There was a hospital mortality of six patients (5%). The mortality was not valve related. The hospital morbidity in 14 revealed full recovery of all patients. There were four late reoperations, in two due to recurrent endocarditis and in the last two because of paravalvar leak. There was a late mortality of four patients (non valve related). The follow-up of these patients revealed full competent aortic stentless valve in 97 patients and only minor jet in nine. Most patients are in functional class I and II. The Aortic stentless concept has proven to be outstanding with the use of the Biocor Aortic stentless valve throughout the current follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)

During the period 1968-1985, aortic valve replacement was performed in 871 patients, 617 males and 254 females aged 49.6 years in mean (15 to 75). Up to the end of 1988, 42 patients (4.8%) were reoperated on because of periprosthetic leakage. In primary surgery, annular calcification was found in 27 of these patients (64%), 17 patients (40%) had a bicuspid valve, and a positive culture from the excised valve was diagnosed in one of three patients with active native endocarditis. Two patients had Marfan's syndrome and two others postendocardial regurgitation. At primary surgery, mechanical prostheses were inserted in every case. Differences between the prosthetic models used could not be shown as regards to the occurrence of periprosthetic leakage. To implant the valve, interrupted everted U-mattress sutures with pledgets appeared to be the best method. Leakage occurred in 21 patients (50%) during their hospital stay and in 18 patients (43%) during the follow-up period of four months. Three others developed leakage two to four years from primary surgery. The main indication for reoperation was congestive heart failure alone or combined with heamolytic anaemia in 37 (88%) of cases. Four patients required the reoperation due to infectious dehiscence. Preoperatively, 34 patients (81%) were in NYHA (The New York Heart Association) Class III-IV. A new prosthetic valve was implanted in 23 cases, a composite graft once and in 18 cases refixation was performed. Two patients died in association with surgery, both due to the low output syndrome. During the follow-up time of 6.4 years, eight patients developed recurrent leakage. Four of them were found during their hospital stay and four others later. The role of prosthetic infection was remarkable in these eight cases; three patients with preoperative infectious dehiscence of the prosthesis had recurrence and one patient developed prosthetic endocarditis with leakage later. Three patients required more reoperations. At follow-up study, leakage was diagnosed in five of 28 living patients. Three of them were not significant and two moderate. 24 patients (86%) were in NYHA Class I-II.

Since age is no longer considered an additional risk factor for cardiac surgery, the epidemiology of valve disease in the elderly at present may be estimated from the surgical pathology evaluation of valve specimens which are resected at the time of valve replacement. In the time interval 1991-1993, 500 patients underwent native cardiac valve replacement or repair at our University, with a total of 549 valves available for gross and histological examination. Single valve surgery was performed in 451 patients (300 aortic, 148 mitral, 3 tricuspid), and double valve replacement in 49 (47 mitral-aortic, 1 aorto-tricuspid and 1 mitral-tricuspid). Two hundred and eighteen patients (44%) were older than 65 years; the mean age was 70.4 +/- 4.3 years, and the male to female ratio was 0.9 to 1. Two-thirds of the interventions in the elderly group were aortic operations. However, regardless of the age group, 50 and 60% of the cases with respectively aortic and mitral valve disease were due to rheumatic disease. Age-related degenerative valve diseases were prominent; senile dystrophic calcification with aortic stenosis mostly in the elderly, anuloaortic ectasia with aortic incompetence mostly in adults, and floppy valve with mitral incompetence in both age groups. Bicuspid aortic valve, a congenital anomaly which is silent until adulthood, accounted for both aortic stenosis and stenoincompetence by dystrophic calcification, and pure aortic incompetence by endocarditis or anuloaortic ectasia. Our findings suggest that although age-related degenerative valve diseases are increasing, rheumatic disease still remains the leading cause of valve dysfunction in our country even in the elderly. These data may have an impact on prevention strategies and health-care costs. However, it has to be pointed out that the high prevalence of rheumatic disease is a feature of this particular study but is different from the findings of other studies around the world.

This report concerns a 29-year-old man with recent Streptococcus viridans endocarditis on a bicuspid aortic valve who was found to have a mycotic aneurysm of the left anterior descending coronary artery and infective erosion and thinning of the posterior wall of the ascending aorta 1.5 to 3.5 cm above the origin of the left coronary artery, a combination of lesions not previously reported. Mycotic aneurysm of the coronary arteries affects less than 1% of patients with infective endocarditis, and there are few reports of the management of these rare lesions. The surgical management of this patient is presented with a brief review of the available literature.

We report two cases of Campylobacter fetus endocarditis. The first case involved a bicuspid native aortic valve in a 60-year-old woman, and the second involved a prosthetic aortic valve in a 76-year-old woman. No source of infection was identified in either case. Despite antibiotic therapy, hemodynamic deterioration necessitated valve replacement; both patients recovered completely. C. fetus is an uncommon cause of human infection but may be responsible for severe illnesses such as endocarditis and thrombophlebitis because of its tendency to attack the vascular endothelium. Review of the literature revealed 21 cases of endocarditis caused by this organism, usually involving the aortic valve. To our knowledge, there are only two reported cases of prosthetic valve endocarditis. Our second patient is the oldest one encountered so far with this condition.

From May 1990 to August 1993, 100 patients underwent aortic valve replacement using the stentless porcine aortic valve. There were 69 males and 31 females. The mean age was 36 (range 11-76) years. Of 70 patients under 40 years of age, 20 were less than 20 years old. Indications included rheumatic heart sequelae in 55 patients (first valve replacement), prosthetic failure in 20, endocarditis in 13, congenital aortic bicuspid valve in four, degenerative disease in four and senile calcified aortic valves in four. Twenty patients had aortic annular related pathology. There were 15 associated surgical procedures. Forty-three patients required aortic root enlargement. There were approximately equal numbers of patients in New York Heart Association (NYHA) functional classes III and IV. The hospital mortality rate was 6%; 14 patients who experienced hospital morbidity had a full recovery. Two late reoperations were performed in patients with primary valve endocarditis; their recovery was uneventful. Four late deaths were not valve related. Comparative echo Doppler analysis before and after operation demonstrated good improvement of left ventricular function in nearly all patients. The valve was competent in 96% of patients and the remainder displayed minor jets without haemodynamic significance. The valve coaptation was stable in all patients. Use of the stentless porcine aortic valve in this first 100 patients has provided excellent clinical results with a follow-up of 41 months. Further follow-up and close observation will be required to analyse the outcome of this new valve and procedure with time.
