Anorexia nervosa (AN) is a psychiatric disorder that may lead to cardiac complications. The objective of this study was to evaluate global and regional longitudinal strain changes in patients affected by AN as an early marker of myocardial damage. We prospectively enrolled 48 consecutive patients with AN and 44 age-matched and gender-matched healthy controls. In all subjects, we performed echocardiography, including global longitudinal strain (GLS) measurement. A subset of 33 patients with AN had further echocardiographic examinations during the follow-up. Compared with healthy controls, patients with AN had a greater prevalence of pericardial effusion (9 of 48 vs 0 of 44, p = 0.003), a smaller left ventricular mass (63 ± 15 vs 99 ± 30 g, p0.001), a lower absolute value of GLS (-18.9 ± 2.8 vs -20.2 ± 1.8%, p = 0.010) and of basal LS (-15.4 ± 6.0 vs -19.4 ± 2.6%, p0.001). The bull's eye mapping showed a plot pattern with blue basal areas in 18 of 48 patients with AN versus 1 of 44 controls (p0.001). During the follow-up, of 13 patients with blue areas in the first bull's eye mapping, 11 recovered completely, and of 20 patients with a red bull's eye at the first examination, none presented blue areas at the second one. In conclusion, GLS is significantly altered in patients with AN, and a basal blue pattern on bull's eye mapping identifies more severe cases. These changes seem to be reversible.

Background: In patients with left-sided infective endocarditis (IE) and heart failure associated with large vegetations, early surgery prevents embolic events. However, optimal timing of surgery for other indications is still unresolved particularly when the presence of large vegetations represents the sole indication. Methods: We retrospectively analyzed 308 consecutive patients admitted to our department with definite left-sided IE. Of these patients, 243 (79%) underwent cardiac surgery (complicated IE), 34 patients with uncomplicated IE received medical treatment, 24 were not operated due to prohibitive general conditions and 7 refused surgery. Long-term follow-up was obtained by structured telephone interviews. Results: During the 6-year follow-up (average 121.8 weeks ± 76), patients not operated because of general conditions or refusal had the worst prognosis, while outcome in operated patients for complicated IE was comparable to that of uncomplicated IE treated medically.

Introduction Drug-induced thrombotic microangiopathy (DITMA) is an acquired condition resulting from exposure to a drug that induces the formation of platelet-rich thrombi in small arterioles or capillaries secondary to drug-dependent antibodies or direct tissue toxicity. Carfilzomib is a selective proteasome inhibitor approved to treat selected patients with Multiple Myeloma (MM). It is one of the drugs with the strongest evidence for a causal association with non-antibody-mediated DITMA. Case Report A 75-year-old man presented to the emergency department for the outbreak of vomit, asthenia, oliguria and dark stool emission. He was recently diagnosed with multiple myeloma, treated with lenalidomide, dexamethasone and carfilzomib. Laboratory exams were significant for microangiopathic haemolytic anaemia, thrombocytopenia and new-onset renal failure. ADAMTS-13 levels were in range, and no infectious signs were found both in blood nor in stool test. Management & Outcome A carfilzomib induced thrombotic microangiopathy was soon suspected. Thus, since daily haemodialysis and supportive care did not seem to get a fast enough recovery, the patient was treated with eculizumab with a good general outcome. Discussion Drug-induced thrombotic microangiopathy is a rare and often life-threatening acquired condition whose diagnosis can be challenging and whose therapy is not always limited to supportive treatment and drug avoidance. Carfilzomib, along with other proteasome inhibitors, is one of the described potential drugs which can trigger such a manifestation.

Introduction Injection drug use (IDU) is a known risk factor for infective endocarditis (IE) and is associated with frequent recurrences, but its prognostic impact is still debated. Moreover, the potential futility of surgery in this population is an unsolved matter. Purpose We aimed to determine the clinical characteristics, the therapeutic strategy, and the prognostic impact of injection drug use IE (IDUIE). Method We retrospectively included in the analysis 454 consecutive episodes of definite active IE admitted in a single surgical centre from January 2012 to December 2020; 14 out of them where a subsequent infective episode of the same patient. Results IDUIE cases were 63 (13.8%), without significant proportional differences over time. IDUIE patients were significantly younger (43.95±10.12 vs 67.84±13.33, p 0.00) and presented fewer comorbidities (p Conclusions IDUIE represents a considerable proportion of overall cases of IE, mainly affecting young people. Staphylococcus aureus is the most common microbiologic agent. IDUIE is not associated with higher mortality but drug abuse is an independent predictor of mortality. Considering that patient with uncomplicated IE treated medically have a better prognosis, we should reserve surgery to patients with a strict indication for it. On the other hand, since there are no predictors of futility of surgery, all patients with a complicated IE should undergo surgery without delay. The main determinant of prognosis in these patients is not IE but drug abuse itself. For this reason, increased focus on addiction treatment following hospital discharge is mandatory to improve long term prognosis. Funding Acknowledgement Type of funding sources: None.

Introduction Most cases of infective endocarditis (IE) involve a single valve, and little is known concerning IE that simultaneously affects two valves. The involvement of more than one valve may imply more severe and extensive cardiac lesions. In these patients, surgery may be challenging. Purpose We aimed to determine the clinical characteristics, the therapeutic strategy, and the prognostic impact of double-valve IE (DVIE). Method We retrospectively included in the analysis 380 consecutive patients with definite active IE in a single surgical centre. The univariate and multivariate long-term survival was analysed by the Kaplan-Meier method and by stepwise Cox proportional hazards models, respectively. We repeated the mortality analysis using the propensity score matching technique, to adjust for baseline differences between SVIE and DVIE groups. Results DVIE occurred in 60 of the total enrolled 380 patients (15.8%) and involved mostly the combination of mitral and aortic valves (N=52, 87%). Most patients had double-native IE (N=38, 63%). Staphylococci were significantly less frequent in patients with double-valve than single-valve IE (SVIE). The proportion of patients undergoing valve repair among those treated surgically was higher for patients with DVIE than for SVIE (p Conclusions DVIE represents a considerable proportion of overall cases of IE, mainly involving aortic and mitral valves, with a jet lesion on the mitral valve; Staphylococcus is significantly less frequent than in SVIE; DVIE is independently associated with higher mortality; finally, mitral valve repair is feasible in a considerable proportion of surgical cases.

Background Valve repair is considered the treatment of choice for native mitral and tricuspid valve regurgitation but the rate of feasibility when the defect is caused by acute infective endocarditis (IE) is debated. We report the experience of valve repair versus replacement following IE in a high-volume surgical center. Methods We retrospectively analyzed 351 consecutive patients (123 women) admitted to our department with definite diagnosis of IE. IE occurred on native valves in 219 patients (62%) and on prosthetic valves in 132 (38%). Among native valves, IE involved the aortic valve in 105 cases (48%), mitral valve in 97 cases (44%) and tricuspid valve in 17 (8%). Since only native mitral and tricuspid valves are elegible for surgical repair, we limited the analysis to this subset (114 patients); of them, 92 (80.7%) underwent surgery (the final cohort) and 22 were treated conservatively, 13 due to absence of surgical indication and 9 due to prohibitive surgical risk. Long-term follow-up was obtained by structured telephone interviews. Primary endpoints were mortality and freedom from recurrent endocarditis. Secondary endpoints were the postoperative incidence of major adverse events (hospitalization for any cause, pace-maker implantation, new onset of atrial fibrillation, sternal dehiscence). Results Mean age at surgery was 61.9 years (SD 14.5). Mean vegetation length was 11.6 mm (SD 8.8). Endocarditis was left-sided in 80 (87%). Among the 92 surgical patients, 58 (63%) underwent valve replacement and 34 valve repair (37%). Mortality was similar between valve repair and replacement (15 vs 12%). Adverse events rate (19% vs 16%) and relapse were not statistically different between repair and replacement procedures. Conclusions The present study shows that a sizeable subgroup of consecutive patients with native mitral or tricuspid IE are amenable to valve repair in expert hands. Outcome of repair in IE is comparable to valve replacement mid-term, and should be considered whenever possible, as in degenerative valve disease.

Background Despite optimal medical and surgical treatment, mortality in infective endocarditis (IE) remains high. Aim of this study was to identify predictors of long term mortality for any cause, adverse event rate, relapse rate and valvular dysfunction at follow-up, in a high-volume surgical center. Methods We retrospectively analyzed 358 consecutive patients (127 women) admitted to our department with definite diagnosis of IE not device-related. IE occurred on native valves in 224 patients (63%); the infection involved the aortic valve in 192 (54%), mitral valve in 139 (39%) and tricuspid valve in 26 (7%). Overall 285 (80%) patients underwent surgery and 73 (20%) were treated conservatively, 38 due to absence of surgical indication and 35 due to refusal or prohibitive surgical risk. Long-term follow-up was obtained by structured telephone interviews. Primary endpoints were all-cause mortality, freedom from recurrent endocarditis, postoperative incidence of major adverse events (hospitalization for any cause, pace-maker implantation, new onset of atrial fibrillation, sternal dehiscence), worsening of left ventricular ejection fraction (LVEF) and valvular dysfunction. Results Mean age was 65 years (SD 15.2). Mean vegetation length was 8.9 mm (SD 7.6). Endocarditis was left-sided in 332 (93%). Average follow-up was 6 months. At univariable analysis, mortality was associated with female gender (p=0.031), age (p Conclusions The present study shows that low EF, EuroSCORE2, procalcitonin levels and diabetes are independent predictors of death in patients with IE. Non-fatal adverse events are more frequent in patients with renal failure. Relapse rate is higher in drug abusers. These informations may help personalize follow-up strategies after acute admission for IE. Funding Acknowledgement Type of funding source: None

Objectives. Valve repair is considered the treatment of choice for native mitral valve regurgitation, although the rate of feasibility when the defect is caused by acute infective endocarditis (IE) is debated. We report the experience of valve repair versus replacement following IE in a high-volume surgical center. Methods. We retrospectively analyzed 363 consecutive patients (123 women) admitted with a diagnosis of definite IE. We selected 108 patients with native mitral IE, potentially eligible for surgical repair. Of these 108, 90 (83%) underwent surgery and 18 were treated conservatively. The two primary endpoints were all-cause mortality and freedom from recurrent endocarditis. Results. Mean age at surgery was 63.6 years (SD 13.5). Mean vegetation length was 11.6 mm (SD 7.7). Among the 90 surgical patients, 57 (63%) underwent valve replacement and 33 valve repair (37%). Mean follow-up duration was three years. All-cause short-term (30 days: 3±3 vs 4±2% for repair and replacement respectively) and long-term (3 years: 26±9 vs. 36±11%) mortality was lower, although not-significantly, for valve repair (figure 1), as well as nonfatal adverse events (15±4 vs. 20±2%) and relapse rate (1±1% vs. 3±1%) at three years. At echocardiographic follow-up, no differences were reported between the two groups in terms of left ventricular systolic function and valvular continence. Conclusions. In our experience, over one-third of consecutive patients with native mitral are amenable to valve repair in expert hands. Mid-term outcome of repair in IE is comparable to valve replacement, and should be considered whenever possible, as in degenerative valve disease.

Background Heart tumors are very rare lesions. Their prevalence is about 0.001 to 0.03 % in an autopsy series. In most cases, primitive lesions are benign, with atrial myxomas that represent up to 2/3 of cases. Malignant neoplasms have a high mortality; sarcomas are the most frequent typologies. The most aggressive tumors are characterized by greater size, muscle invasion and pericardial effusion. Clinical case A 39-year-old man with recent history of worsening dyspnea went to the emergency room because of an aggravation of the symptoms. An echocardiogram showed a large atrial inhomogeneous mass, adherent to the mitral ring and involving both left atrial and ventricle, causing a severe valvular stenosis, suggestive for malignancy. Thus the patient performed a cardiac-MRI, confirming the neoplasm localization with parietal infiltration, pericardial extension and effusion. A total-body CT scan ruled out metastasis. The patient underwent heart surgery and a partial excision was performed. Macroscopically the tumor had a scirrhous consistency and a diameter of about 5 cm. The histologic examination showed a high-grade sarcoma with fused cells and with condrosarcomatous areas. Discussion The study of heart massesincludes the execution of echocardiographies as first-line examinations, while the in-depth diagnostics (necessary in the anticipation of surgery) require cardiac-MRI or CT. Malignant lesions are characterized by an inomogeneous appearance, with a wide plant base and sizes larger than 5 cm, they are also able to take contrast medium during diagnostic examinations. High grade neoplasms are rapidly evolving with a very severe prognosis. The symptoms are essentially due to the localization and the mass bulk. In our case, its development on the mitral valve caused severe hemodynamic impairment, requiring immediate intervention. The treatment of these lesions is necessarily surgical. The only positive prognostic factor is a complete excision of neoplasm with free resection margins. As the diagnosis is often not early, chemotherapy or radiotherapy are often required after surgery. Conclusion Cardiac masses are rare entities and their evaluation may be a diagnostic challenge. Myxoma represent the most common primary cardiac neoplasm in adults, while about 25% of other primary ones are malignant. Our patient was suffering from a sarcoma, whose incomplete debulking made further therapies necessary. The correct interpretation of instrumental findings together with a possible radical surgery are mandatory for a successful therapeutic strategy. Abstract P1306 Figure.

Background Hypocomplementemic Urticarial Vasculitis Syndrome (HUVS) is a very rare disease involving small vessels and characterized by chronic urticarial vasculitis, arthralgia, arthritis, and activation of the classical complement pathway. To our knowledge, just other seven cases of HUVS with cardiac valvular involvement have been reported in the literature. Unlike previous cases, ours shows a broader antibody positivity, (but no anti-C1q antibodies) with an early and serious cardiovascular involvement. Case summary A 32 years old woman was brought to the emergency department because of sudden onset of right hemiplegia and global aphasia due to cerebral haemorrage. She suffered from a severe HUVS form with cardiac valvular involvement and she was cronically treated with immunosuppressant drugs. During previous years she had already undergone cardiac surgery twice for chronic aseptic inflammatory process involving aortic and mitral valves. Right hemiplegia and global aphasia were caused by septic embolism to left cerebral artery complicated by cerebral haemorrage. The patient underwent neurosurgical intervention followed by antibiotic therapy. This condition was secondary to Listeria monocytogenes aortic infective endocarditis in an immunosuppressed patient. Transesophageal echocardiogram showed periaortic abscess with internal colliquation. A further surgical intervention would have been necessary, but operative risk was judged to high and the patient died one year later. Discussion The association between HUVS, Jaccaud"s arthropathy and cardiac valvular disease is rarely described in the literature. The presence of valvular involvement is a negative prognostic factor. Unlike most cases, it is interesting to note that our patient was negative for anti-C1q antibodies and exhibited an extremely severe cardiac involvement. The case was complicated by L monocytogenes endocarditis, that is also a rare condition associated with a high mortality rate. Abstract P1457 Figure. Abscess
