Type A acute aortic dissection with ≥40-mm aortic root: results of conservative and replacement strategies at long-term follow-up. Eur J Cardiothorac Surg 2021; 59:1115-1122. [PMID: 33367649 DOI: 10.1093/ejcts/ezaa456] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 11/04/2020] [Accepted: 11/15/2020] [Indexed: 01/16/2023] Open
Abstract
OBJECTIVES We evaluated the long-term results of aortic root (AR) preservation and replacement in patients operated on for acute type A aortic dissection. METHODS Out of 302 patients discharged after repair of acute aortic dissection (1977-2019), 124 patients had an AR ≥40 mm, which was preserved in 84 (68%, group A) patients and replaced in 40 (32%, group B) patients. Group B patients were younger (mean age 57 ± 12 vs 62 ± 11 years, P = 0.07), with a mean AR of 47 vs 43 mm and ≥moderate aortic insufficiency in 65% vs 30%. Survival, causes of death and reoperations were analysed at mean follow-up of 9 ± 8 years (6 months to 40 years). RESULTS Actuarial survival of discharged patients at 5, 10 and 15 years was 97% (0.89-0.99), 78% (0.67-0.90) and 75% (0.64-0.88) in group A, and 85% (0.71-0.95), 62% (0.44-0.78) and 57% (0.39-0.76) in group B (log-rank test P = 0.2). Nine patients in group A (7 patients for aortic insufficiency and dilatation of the root and 2 patients for pseudoaneurysm) and 1 patient of group B (pseudoaneurysm of the right coronary button) required proximal reoperation without deaths. At 5, 10 and 15 years, the cumulative incidence of proximal aortic reoperations was 5%, 9% and 25% in group A, and 0%, 3% and 3% in group B (P = 0.02). At multivariable analysis AR >45 mm [hazard ratio (HR) 6.8, P = 0.026] and age (HR 0.9, P = 0.016) were independently associated with proximal reoperation. CONCLUSIONS AR preservation in acute type A dissection showed acceptable long-term outcomes. Nevertheless, a more aggressive approach appears a valid option, especially in patients with AR diameter >45 mm.

Abstract
BACKGROUND Stroke is one of the most common and potentially disabling complications of infective endocarditis (IE). However, scarce data exist about stroke complicating IE after transcatheter aortic valve replacement (TAVR). OBJECTIVES The purpose of this study was to determine the incidence, risk factors, clinical characteristics, management, and outcomes of patients with definite IE after TAVR complicated by stroke during index IE hospitalization. METHODS Data from the Infectious Endocarditis after TAVR International Registry (including 569 patients who developed definite IE following TAVR from 59 centers in 11 countries) was analyzed. Patients were divided into two groups according to stroke occurrence during IE admission (stroke [S-IE] vs. no stroke [NS-IE]). RESULTS A total of 57 (10%) patients had a stroke during IE hospitalization, with no differences in causative microorganism between groups. S-IE patients exhibited higher rates of acute renal failure, systemic embolization, and persistent bacteremia (p < 0.05 for all). Previous stroke before IE, residual aortic regurgitation ≥moderate after TAVR, balloon-expandable valves, IE within 30 days after TAVR, and vegetation size >8 mm were associated with a higher risk of stroke during the index IE hospitalization (p < 0.05 for all). Stroke rate in patients with no risk factors was 3.1% and increased up to 60% in the presence of >3 risk factors. S-IE patients had higher rates of in-hospital mortality (54.4% vs. 28.7%; p < 0.001) and overall mortality at 1 year (66.3% vs. 45.6%; p < 0.001). Surgical treatment was not associated with improved outcomes in S-IE patients (in-hospital mortality: 46.2% in surgical vs. 58.1% in no surgical treatment; p = 0.47). CONCLUSIONS Stroke occurred in 1 of 10 patients with IE post-TAVR. A history of stroke, short time between TAVR and IE, vegetation size, valve prosthesis type, and residual aortic regurgitation determined an increased risk. The occurrence of stroke was associated with increased in-hospital and 1-year mortality rates, and surgical treatment failed to improve clinical outcomes.

Abstract
BACKGROUND Isolated tricuspid valve (TV) surgery is a rare procedure generally considered at high risk of perioperative mortality and poor long-term outcomes. Surgical treatment can be performed with either an arrested heart (AH) or beating heart (BH) technique. Aim of this study is to compare the outcomes of isolated tricuspid surgery with two different approaches. METHODS The SUR-TRI study is a multicenter international retrospective study enrolling adult patients who underwent isolated tricuspid valve procedures (n=406, 56±16 years; 56% female) at 13 international sites. AH and BH strategies were performed in 253 and 153 cases, respectively. Propensity score-matched analysis was used to compare groups. RESULTS After matching, 129 pairs were obtained and analyzed. The 30-day mortality rate was 6.2 vs 5.0% in the AH and BH groups, respectively (p=0.9). The rates of acute renal failure requiring replacement therapy (3 vs 10%, p=0.02) and stroke (0 vs 1.8%, p=0.08) were numerically higher in the AH group. The 6-year survival rate was 67±6 vs 78±5% in the AH and BH groups, respectively (p=0.18), while freedom from cardiac death was 75±5 vs 84±4% (p=0.21). The six-year composite cardiac endpoint of cardiac death and reoperation rate was 60±9 vs 86±5% (p=0.024) comparing AH-TV replacement and BH-TV repair groups. CONCLUSIONS Isolated tricuspid valve surgery performed with a beating heart strategy is a safe option and resulted in a trend of increased long-term survival and freedom from reoperation when compared with the standard arrested heart technique. Patients undergoing beating heart valve repair had the best long-term outcome.

Abstract
AIMS The prognosis for patients affected by light-chain cardiac amyloidosis and acquired transthyretin-related (TTR) amyloidosis is poor. Heart transplantation (HTx) could improve prognosis also enabling autologous stem cell transplantation (ASCT) in the first group. METHODS AND RESULTS A total of 36 patients affected by systemic amyloidosis have been referred to our centre from 2009 to 2019. Of these, nine had cardiac involvement: seven by light-chain amyloidosis and two by acquired TTR amyloidosis. None died while waiting for HTx. A specific internal protocol useful to select candidates and to monitor the organ involvement after HTx was developed. Median age at diagnosis was 54 years and 66% were male. The most common short-term complication after HTx was renal failure (44%), followed by acute cardiac rejection more than 2R (22%). ASCT was performed in six out of seven light-chain cardiac amyloidosis patients, with a median time of 6 months after HTx. Two patients affected by light-chain cardiac amyloidosis died due to amyloidosis relapse: one before undergoing ASCT. After a median follow-up of 31 (7-124) months, 1- and 5-year survival was 88 and 66% in the cardiac light-chain amyloidosis group. Conversely, 1- and 5-year survival was 100% in the acquired TTR amyloidosis group. CONCLUSION HTx may represent a valuable option in carefully selected patients. ASCT after HTx is an effective treatment that could decrease amyloidosis relapse in light-chain cardiac amyloidosis patients. A multidisciplinary approach is mandatory to select the best candidates and to obtain the most effective results with a specific surveillance follow-up protocol.

Abstract
BACKGROUND Procedural improvements combined with the contemporary clinical profile of patients undergoing transcatheter aortic valve replacement (TAVR) may have influenced the incidence and outcomes of infective endocarditis (IE) following TAVR. We aimed to determine the temporal trends, characteristics, and outcomes of IE post-TAVR. METHODS Observational study including 552 patients presenting definite IE post-TAVR. Patients were divided in 2 groups according to the timing of TAVR (historical cohort [HC]: before 2014; contemporary cohort [CC]: after 2014). RESULTS Overall incidence rates of IE were similar in both cohorts (CC vs HC: 5.45 vs 6.52 per 1000 person-years; P = .12), but the rate of early IE was lower in the CC (2.29‰ vs 4.89‰, P < .001). Enterococci were the most frequent microorganism. Most patients presented complicated IE ( CC: 67.7%; HC: 69.6%; P = .66), but the rate of surgical treatment remained low (CC: 20.7%; HC: 17.3%; P = .32). The CC exhibited lower rates of in-hospital acute kidney injury (35.1% vs 44.6%; P = .036) and in-hospital (26.6% vs 36.4%; P = .016) and 1-year (37.8% vs 53.5%; P < .001) mortality. Higher logistic EuroScore, Staphylococcus aureus etiology, and complications (stroke, heart failure, and acute renal failure) were associated with in-hospital mortality in multivariable analyses (P < .05 for all). CONCLUSIONS Although overall IE incidence has remained stable, the incidence of early IE has declined in recent years. The microorganism, high rate of complications, and very low rate of surgical treatment remained similar. In-hospital and 1-year mortality rates were high but progressively decreased over time.

Abstract
OBJECTIVES Data on the long-term results with the standard CarboSeal™ mechanical conduit used for the modified Bentall procedure are lacking as well as information on performance of the Valsalva CarboSeal™ conduit. METHODS We have analysed 208 recipients of a standard (n = 110) or a Valsalva (n = 98) CarboSeal™ conduit. The median age was 60 years and 90% were males; 35 (17%) had type A aortic dissection and 65 (30%) a bicuspid aortic valve. Data were retrospectively analysed and results were compared between the 2 conduit models. RESULTS Early mortality was 1.9%; the mean follow-up was 175 ± 95 for standard and 94 ± 51 months for Valsalva conduits (P < 0.01). Actuarial survival was 86 ± 4%, 75 ± 6%, 59 ± 7% and 51 ± 9% at 5, 10, 15 and 20 years, respectively. There were 13 thromboembolic episodes with 3 deaths with an actuarial freedom of 98 ± 1%, 94 ± 2%, 90 ± 3% and 89 ± 4% at 5, 10, 15 and 20 years, respectively. Reoperation on the aortic root was performed in 9 patients for endocarditis (n = 8) and pseudoaneurysm at the right coronary button (n = 1) with an actuarial freedom of 97 ± 1%, 95 ± 2%, 92 ± 3% and 87 ± 4% at 5, 10, 15 and 20 years, respectively. There were no differences between the 2 conduit models in survival and major postoperative complications. CONCLUSIONS The CarboSeal™ conduit has shown gratifying overall performance up to 20 years and appears a valid option for a modified Bentall operation, when a mechanical prosthesis is indicated. Both CarboSeal™ conduit models provided not statistically different overall long-term results.

Abstract
Permanent pacemaker implantation (PPI) represents a rare complication after cardiac surgery, with no uniform agreement on timing and no information on follow-up. A multicenter retrospective study was designed to assess pacemaker dependency (PMD) and long-term mortality after cardiac surgery procedures. Between 2004 and 2016, PPI-patients from 18 centers were followed. Time-to-event data were evaluated with semiparametric regression Cox models and semiparametric Fine and Gray model for competing risk framework. Of 859 (0.90%) PPI-patients, 30% were pacemaker independent (PMI) at 6 months. PMD showed higher mortality compared with PMI (10-year survival 80.1% ± 2.6% and 92.2% +2.4%, respectively, log-rank p-value < 0.001) with an unadjusted hazard ratio for death of 0.36 (95% CI 0.20 to 0.65, p< 0.001 favoring PMI) and an adjusted hazard ratio of 0.19 (95% CI 0.08 to 0.45, p< 0.001 with PMD as reference). Crude cumulative incidence function of restored PMI rhythm at follow-up at 6 months, 1 year and 12 years were 30.5% (95% CI 27.3% to 33.7%), 33.7% (95% CI 30.4% to 36.9%) and 37.2% (95% CI 33.8% to 40.6%) respectively. PMI was favored by preoperative sinus rhythm with normal conduction (SR) (HR 2.37, 95% CI 1.65 to 3.40, p< 0.001), whereas coronary artery bypass grafting and aortic valve replacement were independently associated with PMD (HR 0.63, 95% CI 0.45 to 0.88, p = 0.006 and HR 0.807, 95% CI 0.65 to 0.99, p = 0.047 respectively). Time-to-implantation was not associated with increased rate of PMI. Although 30% of PPI-patients are PMI after 6 months, PMD is associated with higher mortality at long term.

Abstract
OBJECTIVES The aim of this study was to assess the clinical course and outcomes of all heart transplant recipients affected by coronavirus disease-2019 (COVID-19) who were followed at the leading heart transplant centers of Northern Italy. BACKGROUND The worldwide severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic has created unprecedented challenges for public health, demanding exceptional efforts for the successful management and treatment of affected patients. Heart transplant patients represent a unique cohort of chronically immunosuppressed subjects in which SARS-CoV-2 may stimulate an unpredictable clinical course of infection. METHODS Since February 2020, we enrolled all 47 cases (79% male) in a first cohort of patients, with a mean age of 61.8 ± 14.5 years, who tested positive for SARS-CoV-2, out of 2,676 heart transplant recipients alive before the onset of the COVID-19 pandemic at 7 heart transplant centers in Northern Italy. RESULTS To date, 38 patients required hospitalization while 9 remained self-home quarantined and 14 died. Compared to the general population, prevalence (18 vs. 7 cases per 1,000) and related case fatality rate (29.7% vs. 15.4%) in heart transplant recipients were doubled. Univariable analysis showed older age (p = 0.002), diabetes mellitus (p = 0.040), extracardiac arteriopathy (p = 0.040), previous PCI (p = 0.040), CAV score (p = 0.039), lower GFR (p = 0.004), and higher NYHA functional classes (p = 0.023) were all significantly associated with in-hospital mortality. During the follow-up two patients died and a third patient has prolonged viral-shedding alternating positive and negative swabs. Since July 1st, 2020, we had 6 new patients who tested positive for SARS-CoV-2, 5 patients asymptomatic were self-quarantined, while 1 is still hospitalized for pneumonia. A standard therapy was maintained for all, except for the hospitalized patient. CONCLUSIONS The prevalence and mortality of SARS-CoV-2 should spur clinicians to immediately refer heart transplant recipients suspected as having SARS-CoV2 infection to centers specializing in the care of this vulnerable population.

Abstract
BACKGROUND Left ventricular free-wall rupture (LVFWR) is an uncommon but serious mechanical complication of acute myocardial infarction. Surgical repair, though challenging, is the only definitive treatment. Given the rarity of this condition, however, results after surgery are still not well established. The aim of this study was to review a multicenter experience with the surgical management of post-infarction LVFWR and analyze the associated early outcomes. METHODS Using the CAUTION (Mechanical Complications of Acute Myocardial Infarction: an International Multicenter Cohort Study) database, we identified 140 patients who were surgically treated for post-acute myocardial infarction LVFWR in 15 different centers from 2001 to 2018. The main outcome measured was operative mortality. Multivariate analysis was carried out by constructing a logistic regression model to identify predictors of postoperative mortality. RESULTS The mean age of patients was 69.4 years. The oozing type of LVFWR was observed in 79 patients (56.4%), and the blowout type in 61 (43.6%). Sutured repair was used in the 61.4% of cases. The operative mortality rate was 36.4%. Low cardiac output syndrome was the main cause of perioperative death. Myocardial rerupture after surgery occurred in 10 patients (7.1%). Multivariable analysis revealed that preoperative left ventricular ejection fraction (P < .001), cardiac arrest at presentation (P = .011), female sex (P = .044), and the need for preoperative extracorporeal life support (P = .003) were independent predictors for operative mortality. CONCLUSIONS Surgical repair of post-infarction LVFWR carries a high operative mortality. Female sex, preoperative left ventricular ejection fraction, cardiac arrest, and extracorporeal life support are predictors of early mortality.

Abstract
BACKGROUND Cardiac allograft vasculopathy (CAV) is an important cause of late mortality after heart transplantation, which may be influenced by preexisting coronary disease (CAD) in the donor heart. METHODS The aim of this study was to verify whether CAD in the donor heart had any influence on survival, cardiac-related adverse events (CRAEs), and coronary disease progression after transplantation. Donor coronary angiography performed in 289 hearts showed absence of CAD in 232 (no-CAD group) and moderate (≤50%) stenoses (CAD group) in 57. The 2 groups were compared for survival, freedom from CRAEs, and development of grade ≥ 2 CAV after transplantation. RESULTS Of 30-day mortality and postoperative complication rate was similar as mean follow-up (76 ± 56 and 75 ± 55 months) for no-CAD and CAD (P = 0.8). Ten-year actuarial survival was 58 ± 4% and 62 ± 7% for no-CAD and CAD (P = 0.4). Ten-year freedom from grade ≥ 2 CAV and from CRAEs was 81 ± 4% and 66 ± 5% vs 75 ± 8% and 67 ± 9% in no-CAD and CAD (P = 0.9 and 0.9, respectively). CONCLUSIONS Donor hearts with moderate CAD did not affect survival, freedom from CRAEs and did not accelerate development of high-grade CAV after transplantation supporting the use of such grafts to expand the donor pool. Routine use of coronary angiography in donor selection appears justified.

Abstract
The prominent impact that coronary microcirculation disease (CMD) exerts on heart failure symptoms and prognosis, even in the presence of macrovascular atherosclerosis, has been recently acknowledged. Experimental delivery of pericytes in non-revascularized myocardial infarction improves cardiac function by stimulating angiogenesis and myocardial perfusion. Aim of this work is to verify if pericytes (Pc) residing in ischemic failing human hearts display altered mechano-transduction properties and to assess which alterations of the mechano-sensing machinery are associated with the observed impaired response to mechanical cues. RESULTS: Microvascular rarefaction and defects of YAP/TAZ activation characterize failing human hearts. Although both donor (D-) and explanted (E-) heart derived cardiac Pc support angiogenesis, D-Pc exert this effect significantly better than E-Pc. The latter are characterized by reduced focal adhesion density, decreased activation of the focal adhesion kinase (FAK)/ Crk-associated substrate (CAS) pathway, low expression of caveolin-1, and defective transduction of extracellular stiffness into cytoskeletal stiffening, together with an impaired response to both fibronectin and lysophosphatidic acid. Importantly, Mitogen-activated protein kinase kinase inhibition restores YAP/TAZ nuclear translocation. CONCLUSION: Heart failure impairs Pc mechano-transduction properties, but this defect could be reversed pharmacologically.

Abstract
The prevalence of valvular infective endocarditis (IE) is increasing and is burdened by high mortality and morbidity. Despite the higher risk, the surgical approach is superior to medical therapy alone, and over the years there has been a more aggressive attitude, with earlier indications for surgery. This article aims to review the available literature and the American and European guidelines in order to summarize the most appropriate surgical timing for valvular IE. Although there are discrepancies between the guidelines, an emergent indication (<48 h) should be considered in patients with either native or prosthetic endocarditis with severe regurgitation, outflow obstruction, refractory acute pulmonary edema, cardiogenic shock, or large mobile vegetations (>15-20 mm). Patients with signs of heart failure, persistence of positive cultures for more than 48-72 h despite antibiotic therapy, and in the presence of paravalvular lesions, advanced atrioventricular block and vegetations >10 mm should be operated early (within a few days). If any micro-organisms are isolated, including fungi or multi-resistant organisms in native IE or staphylococci or gram-negative pathogens in prosthesis IE, a more watchful approach (within 2 weeks) should be evaluated. In the presence of large cerebral embolic strokes or cerebral hemorrhage, re-evaluation at 2 and 4 weeks, respectively, is more appropriate. A multidisciplinary approach, especially in the most complex cases, seems to improve the outcome.Key words.

Abstract
Abstract
The Djumbodis system is a metallic stent designed to prevent false lumen dilatation after repair of acute aortic dissection. Although the exact number of Djumbodis stents inserted worldwide could not be ascertained from a review of the literature, available data indicate 9 specific device-related complications from 4 patient series and 3 case reports: stent deformity or fracture (4), progressive enlargement of the distal false lumen (3) and distal pseudoaneurysm (1); a further patient with pseudoaneurysm of the distal suture line is added from personal observation. The present review confirms the inability of the Djumbodis stent to provide reduction and/or elimination of the false lumen after repair of type A dissection, highlighting peculiar device-related complications. Current survivors with a Djumbodis stent should undergo close follow-up to prevent possible catastrophic events due to device failure.

Abstract
AIMS We aimed to describe how treatment of patients in cardiogenic shock bridged to heart transplantation with mechanical circulatory support, using either biventricular assist devices (BVADs) or extracorporeal life support (ECLS), has evolved in the last 20 years in our centre. METHODS Since 1998, 72 patients with refractory heart failure and indication for heart transplantation have received mechanical circulatory support: 40 had an ECLS system and 32 a BVAD. RESULTS Early mortality was similar (17.5 vs. 9.4%, P = 0.25) regardless of the type of support. After a median support time of 8 (1-27) vs. 34 (0-385) days (P < 0.01), 70 vs. 65.6% (P = 0.69) of patients underwent transplantation in the two groups. Prior to transplantation, BVAD patients were more stable with lower need for mechanical ventilation (9 vs. 57%, P < 0.01) and dialysis (0 vs. 38%, P < 0.01). Thirty-day mortality after transplantation was similar (18 vs. 14%, P = 0.53). Patients with extracorporeal support had higher rates of renal (P = 0.02) and respiratory failure (P = 0.03), infections (P = 0.02), atrial fibrillation (P = 0.03) and longer ICU stay (P = 0.01). Late survival was similar, while 5-year freedom from coronary vasculopathy was higher in those with BVAD (P = 0.03). CONCLUSION Although ECLS provides faster and simpler assistance compared with BVADs, no differences in early and medium-term outcomes in the last 20 years were observed in patients with cardiogenic shock. However, BVADs provided longer duration of support, better multiorgan recovery allowing more adequate graft selection, resulting in a lower rate of posttransplant complications.

Abstract
To evaluate the impact of donor-recipient age matching on clinical outcomes after heart transplantation, a total of 509 patients (January 1990-December 2018, mean follow-up 111 ± 80 months) were stratified into 4 groups (young-R/young-D, young-R/old-D, old-R/young-D, old-R/old-D) according to the recipient (young-R < 60, old-R ≥ 60 years) and the donor (young-D < 50, old-D ≥ 50 years) age. No difference was found among 30-day mortality (P = .11) and postoperative complications between groups. Both unadjusted and adjusted survival was significantly higher for group young-R/young-D than that of other groups, in which survival was similar [adjusted HR for mortality of 2.0(1.2-3.4), 2.1(1.4-3.8) and 2.5(1.6-4.1) for groups old-R/young-D, young-R/old-D, old-R/old-D, respectively]. Compared to other groups, the incidence of grade ≥ 2 CAV was significantly lower in old-R/young-D group [adjusted HR 0.4(0.2-0.7)]. Among young recipients, the rate of acute grade ≥ 2 rejection episodes was higher in those receiving an old donor graft (P = .04). Old recipient groups were more affected by neoplasms and severe renal failure than young recipient groups (P < .01). Employment of hearts from donors ≥50 years of age adversely affects survival in recipients <60 years of age but does not influence outcomes in older recipients. Also, donor and recipient ages seem to have opposite effects on incidence of rejections and CAV of high grade.

Abstract
Abstract
OBJECTIVES
Endocarditis after the Bentall procedure is a severe disease often complicated by a pseudoaneurysm or mediastinitis. Reoperation is challenging but conservative therapy is not effective. The aim of this study was to assess short- and midterm outcomes of patients reoperated on for Bentall-related endocarditis.
METHODS
Seventy-three patients with Bentall procedure-related endocarditis were recorded in the Italian registry. The mean age was 57 ± 14 years and 92% were men; preoperative comorbidities included hypertension (45%), diabetes (12%) and renal failure (11%). The logistic EuroSCORE was 25%; the EuroSCORE II was 8%.
RESULTS
Preoperatively, 12% of the patients were in septic shock; left ventricular-aortic discontinuity was present in 63% and mitral valve involvement occurred in 12%. The most common pathogens were Staphylococcus aureus (22%) and Streptococci (14%). Reoperations after a median interval of 30 months (1–221 months) included a repeat Bentall with a bioconduit (41%), a composite mechanical (33%) or biological valved conduit (19%) and a homograft (6%). In 1 patient, a heart transplant was required (1%); in 12%, a mitral valve procedure was needed. The hospital mortality rate was 15%. The postoperative course was complicated by renal failure (19%), major bleeding (14%), pulmonary failure (14%), sepsis (11%) and multiorgan failure (8%). At multivariate analysis, urgent surgery was a risk factor for early death [hazard ratio 20.5 (1.9–219)]. Survival at 5 and 8 years was 75 ± 6% and 71 ± 7%, with 3 cases of endocarditis relapse.
CONCLUSIONS
Surgery is effective in treating endocarditis following the Bentall procedure although it is associated with high perioperative mortality and morbidity rates. Endocarditis relapse seems to be uncommon.

Abstract
Saprochaete species infection is a rare fungal disease reported so far only in immunocompromised patients. We describe the first case of aortitis caused by Saprochaete capitata, presenting as ascending aorta aneurysm, with secondary endophthalmitis in an immunocompetent patient. Infection by Saprochaete capitata is potentially fatal, with a mortality ranging from 50% to 90% of cases. In the present case aortic aneurysm caused by Saprochaete capitata aortitis was successfully treated by the combination of accurate diagnosis with surgical and specific antifungal therapy.
