ABSTRACT
BACKGROUND: Scarce data are available comparing infective endocarditis (IE) following surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR). This study aimed to compare the clinical presentation, microbiological profile, management, and outcomes of IE after SAVR versus TAVR. METHODS: Data were collected from the "Infectious Endocarditis after TAVR International" (enrollment from 2005 to 2020) and the "International Collaboration on Endocarditis" (enrollment from 2000 to 2012) registries. Only patients with an IE affecting the aortic valve prosthesis were included. A 1:1 paired matching approach was used to compare patients with TAVR and SAVR. RESULTS: A total of 1688 patients were included. Of them, 602 (35.7%) had a surgical bioprosthesis (SB), 666 (39.5%) a mechanical prosthesis, 70 (4.2%) a homograft, and 350 (20.7%) a transcatheter heart valve. In the SAVR versus TAVR matched population, the rate of new moderate or severe aortic regurgitation was higher in the SB group (43.4% vs 13.5%; P < .001), and fewer vegetations were diagnosed in the SB group (62.5% vs 82%; P < .001). Patients with an SB had a higher rate of perivalvular extension (47.9% vs 27%; P < .001) and Staphylococcus aureus was less common in this group (13.4% vs 22%; P = .033). Despite a higher rate of surgery in patients with SB (44.4% vs 27.3%; P < .001), 1-year mortality was similar (SB: 46.5%; TAVR: 44.8%; log-rank P = .697). CONCLUSIONS: Clinical presentation, type of causative microorganism, and treatment differed between patients with an IE located on SB compared with TAVR. Despite these differences, both groups exhibited high and similar mortality at 1-year follow-up.

INTRODUCTION: Right-side infective endocarditis (RSIE) is caused by microorganisms and develops into intracardiac and extracardiac complications with high in-hospital and 1-year mortality. Treatments involve antibiotic and surgical intervention. However, those presenting with extremes e.g. heart failure, or septic shock who are not ideal candidates for conventional medical therapy might benefit from minimally invasive procedures. OBJECTIVE: This review summarizes existing observational studies that reported minimally invasive procedures to debulk vegetation due to infective endocarditis either on valve or cardiac implantable electronic devices. METHODS: A targeted literature review was conducted to identify studies published in PubMed/MEDLINE, EMBASE, and Cochrane Central Database from January 1, 2015 to June 5, 2023. The efficacy and/or effectiveness of minimally invasive procedural interventions to debulk vegetation due to RSIE were summarized following PRISMA guidelines. RESULTS: A total of 11 studies with 208 RSIE patients were included. There were 9 studies that assessed the effectiveness of the AngioVac system and 2 assessed the Penumbra system. Overall procedure success rate was 87.9%. Among 8 studies that reported index hospitalization, 4 studies reported no death, while the other 4 studies reported 10 deaths. CONCLUSIONS: This study demonstrates that multiple systems can provide minimally invasive procedure options for patients with RSIE with high procedural success. However, there are mixed results regarding complications and mortality rates. Further large cohort studies or randomized clinical trials are warranted to assess and/or compare the efficacy and safety of these systems.

AIMS: Debulking of infective mass to reduce the burden if infective material is a fundamental principle in the surgical management of infection. The aim of this study was to investigate the validity of this principle in patients undergoing transvenous lead extraction in the context of bloodstream infection (BSI). METHODS AND RESULTS: We performed an observational single-centre study on patients that underwent transvenous lead extraction due to a BSI, with or without lead-associated vegetations, in combination with a percutaneous aspiration system during the study period 2015-22. One hundred thirty-seven patients were included in the final analysis. In patients with an active BSI at the time of intervention, the use of a percutaneous aspiration system had a significant impact on survival (log-rank: P = 0.0082), while for patients with a suppressed BSI at the time of intervention, the use of a percutaneous aspiration system had no significant impact on survival (log-rank: P = 0.25). CONCLUSION: A reduction of the infective burden by percutaneous debulking of lead vegetations might improve survival in patients with an active BSI.

BACKGROUND: Mitral valve (MV) disease is the most common form of valvular heart disease. Findings that indicate women have a higher risk for unfavorable outcomes than men remain controversial. This study aimed to determine the sex-based differences in epidemiological distributions and outcomes of surgery for MV disease.MethodsâandâResults: Overall, 18,572 patients (45.3% women) who underwent MV surgery between 2001 and 2018 were included. Outcomes included in-hospital death and all-cause mortality during follow up. Subgroup analysis was conducted across different etiologies, including infective endocarditis (IE), degenerative, ischemic, and rheumatic mitral pathology. The overall MV repair rate was lower in women than in men (20.5% vs. 30.6%). After matching, 6,362 pairs (woman : man=1 : 1) of patients were analyzed. Women had a slightly higher risk for in-hospital death than men (10.8% vs. 9.8%; odds ratio [OR]: 1.11, 95% confidence interval [CI]: 0.99-1.24; P=0.075). Women tended to have a higher incidence of de novo dialysis (9.8% vs. 8.6%; P=0.022) and longer intensive care unit stay (8 days vs. 7.1 days; P<0.001). Women with IE had poorer in-hospital outcomes than men; however, there were no sex differences in terms of all-cause mortality. CONCLUSIONS: Sex-based differences of MV intervention still persist. Although long-term outcomes were comparable between sexes, women, especially those with IE, had worse perioperative outcomes than men.

Mitral valve aneurysm (MVA) is characterized by a saccular outpouching of the mitral leaflet, and it represents a rare condition typically associated with aortic valve endocarditis. Three-Dimensional Transesophageal Echocardiography (3D-TEE) serves as an effective tool for detecting the presence of MVA and its potential complications. In this report, we present a case involving a young man with striking images of bicuspid aortic valve endocarditis complicated by an aortic root abscess and multiple perforated mitral valve aneurysms, diagnosed using 3D TEE. This case suggests the uncommon coexistence of Marfan like morphotype, bicuspid aortic valve, and infective endocarditis as a triple mechanism in the occurrence of MVA. It underscores the significance of early and accurate imaging diagnosis for facilitating prompt surgical intervention.

A 60-year-old man presented with breathlessness. Nearly four decades previously, he had required three operations for Staphylococcus aureus infective endocarditis of the tricuspid valve and had received a bioprosthetic valve. He had critical tricuspid bioprosthesis stenosis which was treated successfully by valve-in-valve transcatheter tricuspid valve replacement using a balloon-expandable transcatheter heart valve. One year after intervention, the patient is well with no tricuspid valve stenosis or regurgitation.

OBJECTIVES: To estimate the association between early surgery and the risk of mortality in patients with left-sided infective endocarditis in the context of stroke. DESIGN: Retrospective cohort study. SETTING: This study was a multiinstitution study based on the Chang Gung Research Database, which contains electronic medical records from 7 hospitals in northern and southern Taiwan; these include 2 medical centers, 2 regional hospitals, and 3 district hospitals. PARTICIPANTS: Patients with active left-sided infective endocarditis who underwent valve surgery between September 2002 and December 2018. INTERVENTIONS: The authors divided patients into 2 groups, with versus without preoperative neurologic complications, had undergone early (within 7 d) or later surgery, and with brain ischemia or hemorrhage. MEASUREMENTS AND MAIN RESULTS: Three hundred ninety-two patients with a median time from diagnosis to surgery of 6 days were included. No significant differences in postoperative stroke, in-hospital mortality, or follow-up outcomes were observed between the patients with and without neurologic complications. Among the patients with preoperative neurologic complications, patients who underwent early surgery had a lower 30-day postoperative mortality rate (13.1% v 25.8%; hazard ratio, 0.21; 95% CI 0.07-0.67). In the subgroup analysis of the comparison between brain ischemia and hemorrhage groups, there was no significant between-group difference in the in-hospital outcomes or outcomes after discharge. CONCLUSIONS: Early cardiac surgery may be associated with more favorable clinical outcomes in patients with preoperative neurologic complications. Thus, preoperative neurologic complications should not delay surgical interventions.

Prosthetic valve endocarditis (PVE) is rare but devastating. A 69-year old man admitted for active endocarditis caused by Streptococcus pasteurianus. Antibiotic therapy was started, but the patient developed bowel obstruction owing to cancer with multiple liver metastases, and underwent transverse colectomy. Following colectomy, antibiotic agent was given continued for 4 weeks after and mitral valve replacement( MVR) using a bioprosthesis was performed. Oral antibiotic therapy was continued for six months after MVR to avoid infection recurrence. One year after MVR, the size of multiple liver metastases increased despite oral anticancer drugs administration. A totally implantable central venous access port( CV port) was placed and intravenous chemotherapy was started for progressive metastatic colorectal cancer. But the CV port was removed due to device infection caused by multiple drug resistant Staphyrococcus lugdunensis one month later, but the patient developed prosthetic valve endocarditits( PVE) due to the same bacterium, that caused valve stenosis. Redo MVR was indicated because of progressive dyspnea and uncontrollable fever. The patient was discharged one month after redo MVR, but suffered carcinomatous peritonitis, and eventually died eight months post-discharge. Chemotherapy needs caution because of potential risk of PVE in patients with prosthetic valves, especially for those with a history of infectious endocarditis.

INTRODUCTION: Pulsed lavage irrigation (PLI) is a procedure used to wash contaminated soft tissues and prevent infection in orthopedic surgery. We applicated PLI for surgical treatment of infective endocarditis( IE). SUBJECTS AND METHODS: From January 2017 to June 2021, 6 cases underwent surgical treatment IE using PLI. We investigated an efficacy of PLI. RESULTS: Infected valves were mitral valve in 4 cases, aortic valve in 1 case, and aortic prosthetic valve in 1 case. The performed procedures were mitral valve plasty in 4 cases, aortic valve replacement in 1 case, and 1 removal of vegetation on the aortic prosthetic valve. No recurrence of IE or no deterioration of the native valve or the prosthetic valve was observed in follow-up periods. CONCLUSION: PLI was useful for surgical treatment of IE because of no recurrence of IE or no deterioration of native mitral valves or the aortic prosthetic valve.

OBJECTIVE: Infective endocarditis (IE) caused by Staphylococcus species (spp.) is believed to be associated with higher morbidity and mortality rates. We hypothesize that Staphylococcus spp. are more virulent compared with other commonly causative bacteria of IE with regard to short-term and long-term mortality. BACKGROUND: It remains unclear if patients suffering from IE due to Staphylococcus spp. should be referred for surgical treatment earlier than other IE patients to avoid septic embolism and to optimize perioperative outcomes. MATERIALS AND METHODS: The database of the CAMPAIGN registry, comprising 4917 consecutive patients undergoing heart valve surgery, was retrospectively analyzed. Patients were divided into 2 groups with regard to the identified microorganisms: Staphylococcus group and the non- Staphylococcus group. The non- Staphylococcus group was subdivided for further analyses: Streptococcus group, Enterococcus group, and all other bacteria groups. RESULTS: The respective mortality rates at 30 days (18.7% vs 11.8%; P <0.001), 1 year (24.7% vs 17.7%; P <0.001), and 5 years (32.2% vs 24.5%; P <0.001) were significantly higher in Staphylococcus patients (n=1260) compared with the non- Staphylococcus group (n=1787). Multivariate regression identified left ventricular ejection fraction <30% ( P <0.001), chronic obstructive pulmonary disease ( P =0.045), renal insufficiency ( P =0.002), Staphylococcus spp. ( P =0.032), and Streptococcus spp. ( P =0.013) as independent risk factors for 30-day mortality. Independent risk factors for 1-year mortality were identified as: age ( P <0.001), female sex ( P =0.018), diabetes ( P =0.018), preoperative stroke ( P =0.039), chronic obstructive pulmonary disease ( P =0.001), preoperative dialysis ( P <0.001), and valve vegetations ( P =0.004). CONCLUSIONS: Staphylococcus endocarditis is associated with an almost twice as high 30-day mortality and significantly inferior long-term outcome compared with IE by other commonly causative bacteria. Patients with Staphylococcus infection are more often female and critically ill, with >50% of these patients suffering from clinically relevant septic embolism. Early diagnosis and referral to a specialized center for surgical treatment are strongly recommended to reduce the incidence of preoperative deterioration and stroke due to septic embolism.

BACKGROUND: Patients with chronic renal failure on hemodialysis carry a significant risk of infective endocarditis (IE), but data on whether these patients differ from other patients with IE in terms of comorbidity, microbiology, rates of surgery and mortality are sparse. METHODS: Using Danish nationwide registries, all patients with IE diagnosed between February 1, 2010, and May 14, 2018 were identified and categorized into a "hemodialysis group" and a "non-hemodialysis group." Patient groups were compared by comorbidities, microbiological etiology, cardiac surgery, and mortality. Risk factors associated with mortality were assessed in multivariable Cox regression analysis. RESULTS: In total, 4,366 patients with IE were included with 226 (5.2%) patients in the hemodialysis group. Patients in the hemodialysis group were younger (66.0 years [IQR 53.8-74.9] vs 72.2 years [IQR 62.2-80.0]), had more comorbidities and were surgically treated less often (10.6% vs 20.8%), compared with patients from the nonhemodialysis group. Staphylococcus aureus was more than twice as prevalent (58.0% vs 26.5%). No difference in in-hospital mortality was found between the 2 groups (20.8% vs 18.5%), but 1- and 5-year mortality were significantly higher in the hemodialysis group than in the nonhemodialysis group (37.7% vs 17.7% and 72.1% vs 42.5%, respectively). In adjusted analysis, hemodialysis was associated with higher 1-year (HR = 2.71, 95% CI 2.07-3.55) and 5-year mortality (HR = 2.72, 95% CI 2.22-3.34) CONCLUSIONS: Patients with IE on chronic hemodialysis were younger, had more comorbidity, a higher prevalence of Staphylococcus aureus IE, and a higher mortality than patients without hemodialysis.

Intracardiac masses adhering to the tricuspid valve can occur as a result of right-sided infective endocarditis, malignancy, clot formation in the right atrium, or clots-in-transit passing through the right atrium. Early surgical intervention is recommended for tricuspid valve vegetation in some patients, although open heart surgery is not always an option. Treatment options for right heart thrombi include anticoagulation, thrombolysis, surgical embolectomy, or mechanical aspiration. We present a case series of tricuspid valve debulking using aspiration with the FlowTriever System.

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) continues to be the most common modality of treating aortic stenosis in the United States. While infective endocarditis (IE) and its outcomes have been well documented after surgical aortic valve replacement, the incidence and outcomes of early IE after TAVI have not been well described. METHODS: All patients who underwent TAVI from 2012 through 2018 were identified using the National Readmission Database. Among them, patients who underwent TAVI at the index admission and readmitted within 90 days were included. Patients who died or had IE during the index admission were excluded. Clinical outcomes were compared between patients readmitted with IE (IE group) and those without (non-IE group). RESULTS: A total of 168,283 patients were readmitted to a hospital within 90 days after TAVI. The median age of the IE group and non-IE group were 81 and 82 years old, respectively (p = 0.21). Of those, 525 (0.3%) were readmitted with IE. The median time from TAVI to readmission was 20 days. During readmissions, 11.6% of the IE group died while only 3.15% of the non-IE group experienced death (p < 0.001). The most common causative organism of IE was enterococcus (22.1%). Multivariable analysis revealed that congestive heart failure, cerebrovascular disease, dialysis, concomitant valve disease, Medicaid, and discharge to a facility were independently associated with readmission with IE within 90 days. CONCLUSION: The incidence of readmission with IE is low after TAVI. However, the mortality was markedly high during readmissions. Surgical intervention was rarely performed for IE during the first admission. Enterococcus was the most common organism observed in IE after TAVI.

A 70-year-old man with history of transcatheter aortic valve-in-valve implantation was admitted because of suspected infective endocarditis (IE). Transesophageal echocardiogram did not reveal any vegetations, as the metallic stent frames caused significant artifacts. Position emission tomography was also negative. Intracardiac echocardiogram (ICE) was performed retrogradely through the ascending aorta, which showed clear vegetations over the stent frame of the transcatheter heart valve. Endocarditis after transcatheter aortic valve implantation was not uncommon. With increasing use of valve-in-valve procedures, echocardiographic diagnosis of IE would be more challenging. This case demonstrated the advantage of ICE over conventional echocardiography in visualizing the neo-aortic valve complex for diagnosing IE.

BACKGROUND: Osler's nodes, Janeway lesions and splinter haemorrhages are cutaneous manifestations of infective endocarditis. They occur due to vascular occlusion by septic emboli and a resulting localized vasculitis. They are usually bilateral. We report a case of unilateral Osler's nodes, Janeway lesions and splinter haemorrhages due to an ipsilateral surgical arterio-venous fistula infection. CASE PRESENTATION: A fifty-two-year-old Sri Lankan female with end stage kidney disease presented with fever for five days with blurred vision, pain and redness of the right eye. She had a left brachio-cephalic arterio-venous fistula (AVF) created one month back. She complained of a foul-smelling discharge from the surgical site for past three days. Redness of the right eye with a hypopyon was noted. AVF site over the left cubital fossa was infected with a purulent discharge. Osler's nodes, Janeway lesions and splinter haemorrhages were noted in the distal fingers, thenar and hypothenar eminences of the left hand. Right hand and both feet were normal. No cardiac murmurs were heard. Blood cultures, vitreous sample cultures and pus cultures from the fistula site were all positive for methicillin sensitive Staphylococcus aureus. Infective endocarditis was excluded by a trans-oesophageal echocardiogram. She was treated with IV flucloxacillin and surgical excision of the AVF. CONCLUSION: Infections of AVF can result in septic emboli formation which can have both anterograde arterial embolization and retrograde venous embolization. Arterial embolization can result in unilateral Osler's nodes, Janeway lesions and splinter haemorrhages. Venous embolization can cause metastatic infections in the systemic and pulmonary circulations.

BACKGROUND: Infective endocarditis (IE) is a severe disease associated with high morbidity and mortality. Little is known about the best management of elderly patients with IE. In these patients, surgery may be challenging. Our study aimed to describe IE's features in octogenarians and to identify the independent predictors of mortality, focusing on the prognostic impact of disability. METHODS: We retrospectively analyzed 551 consecutive patients admitted to a single surgical centre with a definite diagnosis of non-device-related infective endocarditis; of these, 97 (17.6%) were older than 80 years. RESULTS: In patients under eighty, males were mostly involved with a sex ratio exceeding 2:1. This ratio was inverted in older people, where the female gender represented 53.6% of the total. Enterococci (29.8 vs. 17.4%, p = 0.005) were significantly more frequent than in younger people. Comorbidities were more frequent in elderly patients; consequently, EuroSCORE II was higher (median ± IQR 16.4 ± 21.1 vs. 5.0 ± 10.3, p = 0.001). In octogenarians, IE was more frequently left-sided (97.9 vs. 89.8%, p = 0.011). Octogenarians were more often excluded from surgery despite indication (23.7 vs. 8.1%, p = 0.001) and had higher three-year mortality (45.3 vs. 30.6%, p = 0.005) than younger patients. In elderly patients, age did not independently predict mortality, while exclusion from surgery and a high grade of disability did. CONCLUSIONS: Octogenarians with IE have specific clinical and microbiological characteristics. Older patients are more often excluded from surgery, and the overall prognosis is poor. Age per se should not be a reason to deny surgery, while disability predicts futility.

BACKGROUND: The optimal treatment strategy for intravenous drug users (IVDU) with infective endocarditis (IE) is controversial. We therefore sought to investigate outcomes among IVDUs after surgery for IE. METHODS: We retrospectively reviewed all 192 consecutive patients who underwent an operation for IE between 2005 and 2016 in the Helsinki University Hospital. Forty-seven patients (24.5%) were IVDUs and 145 (75.5%) were non-IVDUs. Mortality and reinfection and reoperation rates were evaluated. RESULTS: IVDUs were younger (29.9 vs. 63.8 years, p < 0.001) and had less cardiovascular risk factors and lower EuroSCORE II (4.3 vs. 7.3%, p < 0.001), but Staphylococcus aureus infection (66.0 vs. 23.4%, p < 0.001), tricuspid valve endocarditis (34.0 vs. 2.8%, p < 0.001), and liver disease (63.8 vs. 2.8%, p < 0.001) occurred more often in IVDUs than in non-IVDUs. Thirty-day mortality of IVDUs was 8.5% and that of non-IVDUs was 6.9% (p = 0.711). Survival of IVDUs at 5 years was 70.8 ± 7.4% and survival of non-IVDUs was 67.9 ± 4.7% (p = 0.678). Relative to an age- and sex-matched general population, IVDUs had 58.6 (95% confidence interval [CI]: 33.7-101.9; p < 0.001) and non-IVUD 4.4 (95% CI: 3.1-6.2; p < 0.001) standardized mortality ratio. IVDUs had a higher reinfection rate at 5 years (25.8 ± 7.7% vs. 3.0 ± 1.7%, p < 0.001) and a higher early reoperation rate than non-IVDUs (10.6 vs. 1.4%, p = 0.003). CONCLUSIONS: IVDUs and non-IVDUs had comparable survival at 5 years, but IVDUs had a very significantly increased risk of death in comparison to an age- and sex-matched general population. IVDUs had higher reinfection and early reoperation rates. Survival was poor after medically treated reinfection.

BACKGROUND: Endocarditis is continuously increasing. Evidence exist that the prognosis is adversely affected by the extent of the disease. We looked at risk factors influencing in-hospital mortality (HM). PATIENTS AND METHODS: Between 2010 and 2019, 484 patients, 338 males (69.8%) with mean age of 66.1 years were operated on because of proven endocarditis. In a retrospective study, a risk factor analysis was performed. RESULTS: Overall HM was 30.17%. Significant influencing factors (odds ratios [ORs] or p-value) for HM were: age (p = 0.004), logistic EuroSCORE (p< 0.001), gender (OR = 1.64), dialysis (OR = 2.64), hepatic insufficiency (OR = 2.17), reoperation (OR = 1.77), previously implanted valve (OR = 1.97), periannular abscess (OR = 9.26), sepsis on admission (OR = 12.88), and number of involved valves (OR = 1.96). Development of a sepsis and HM was significantly lower if Streptococcus mitis was the main pathogen in contrast to other bacteria (p< 0.001). Staphylococcus aureus was significantly more often found in patients with a previously implanted prosthesis (p = 0.03) and in recurrent endocarditis (p = 0.02), while it significantly more often showed peripheral septic emboli than the other pathogens (p< 0.001). CONCLUSION: Endocarditis remains life-threatening. Severe comorbidities adversely affected early outcome, particularly, in presence of periannular abscesses. Patients with suspected endocarditis should be admitted to a specialized heart center as early as possible. Streptococcus mitis appears to be less virulent than S. aureus. Further studies are required to verify these findings.

OBJECTIVE: The rising incidence of infective endocarditis (IE) accompanied by the de-escalation of antibiotic prophylaxis and the complexity of surgical treatment makes IE a daunting foe. We reviewed all patients who underwent cardiac surgery for IE at our institution with a focus on causative organisms and infective foci. METHODS: A review of 3,952 consecutive patients who underwent cardiac surgery at our institution between January 2013 and December 2017 revealed 160 patients (4%) who were operated for IE. RESULTS: The predominantly affected valves were the aortic (30%) and mitral valve (26.9%) as well as a combination of both (8.8%). A total of 28.8% of patients suffered from prosthetic valve endocarditis (PVE). The most frequently identified causative organisms were Staphylococcus (45.7%), Streptococcus (27.5%), and Enterococcus species (16.7%), which was predominantly associated with PVE (p = 0.050). In 13.1% of patients, a causative organism has not been detected. The most frequent infective foci were dental (15%), soft-tissue infections (15%), spondylodiscitis (10%), and infected intravascular implants (8.8%). Relevant predisposing factors were immunosuppression (9.4%) and intravenous drug abuse (4.4%). Septic cerebral infarctions were diagnosed in 28.8% of patients. Postoperative mortality was 22.5%. CONCLUSIONS: As the bacterial spectrum and the infective foci are still the "old acquaintances," and with regard to the increasing incidence of IE, current risk-benefit evaluations concerning antibiotic prophylaxis may need to be revisited.

BACKGROUND: This study was conducted to evaluate the mid-term outcomes of rapid-deployment aortic valve replacement (AVR) using Edwards Intuity. METHODS: A total of 215 patients underwent rapid-deployment AVR using Edwards Intuity at our institution. The median follow-up duration was 22 months (interquartile range, 8-36). Primary outcomes were overall survival, cumulative incidence of cardiac death, and major adverse cardiac events. Secondary outcomes were early and 1-year hemodynamic performances of the bioprosthetic valve. RESULTS: The mean age was 68.6 ± 10.5 years, and EuroSCORE II was 3.09 ± 4.5. The study population included 113 patients (52.6%) with bicuspid valves (24 patients with type 0 bicuspid valves), 20 patients (9.3%) with pure aortic regurgitation, and 3 patients (1.4%) with infective endocarditis. Isolated AVR was performed in 70 patients (32.4%) and concomitant procedures were performed in 146 patients (67.6%), including aorta surgery (42.3%) and mitral valve procedure (22.3%). Operative mortality was 2.8%. Complete atrioventricular block occurred in 12 patients, but most of them were transient and only 3 patients received permanent pacemaker implantation before discharge. Overall survival at 3 years was 92.3%. Early hemodynamic data showed mean pressure gradients of 15.5 ± 5.0 and 12.7 ± 4.2 mm Hg in the 19 and 21 mm valve, respectively. One-year hemodynamics were also excellent with mean pressure gradients of 14.7 ± 5.3 and 10.7 ± 3.6 mm Hg in the 19 and 21 mm valve, respectively. CONCLUSION: Based on a real-world all-comers population, rapid-deployment AVR using Edwards Intuity could be performed for various indications, including bicuspid valve, pure aortic regurgitation, and infective endocarditis, and the clinical and hemodynamic outcomes were excellent.
