Abstract
Infective endocarditis can involve a normal, abnormal, or prosthetic cardiac valve. The diagnosis is typically made clinically with persistently positive blood cultures, characteristic signs and symptoms, and echocardiographic evidence of valvular vegetations or valvular complications such as abscess, dehiscence, or new regurgitation. Imaging plays an important role in the initial diagnosis of infective endocarditis, identifying complications, prognostication, and informing the next steps in therapy. This document outlines the initial imaging appropriateness of a patient with suspected infective endocarditis and for additional imaging in a patient with known or suspected infective endocarditis. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
OBJECTIVES In patients with unknown coronary status undergoing surgery for acute infective endocarditis (IE), the need to screen for coronary artery disease (CAD) and the risk of embolization during invasive coronary angiography (ICA) are debated. Coronary computed tomography angiography (CCTA) is a non-invasive alternative in these patients. We aimed to evaluate the safety and feasibility of ICA and CCTA to diagnose CAD, and the necessity to treat CAD to prevent CAD-related postoperative complications. METHODS In this single-centre retrospective cohort study, all patients with acute aortic IE between 2009 and 2019 undergoing surgery were selected. Outcomes were any clinically evident embolization after preoperative ICA, in-hospital mortality, perioperative myocardial infarction or unplanned revascularization and postoperative renal function. RESULTS Of the 159 included patients, CAD status was already known in 14. No preoperative diagnostics for CAD was done in 46/145, a CCTA was performed in 54/145 patients and an ICA in 52/145 patients. Significant CAD was found after CCTA in 22% and after ICA in 21% of patients. In 1 of the 52 (2%) patients undergoing preoperative ICA, a cerebral embolism occurred. The rate of perioperative myocardial infarction or unplanned revascularization in patients not screened for CAD was 2% (1 out of 46 patients). CONCLUSIONS Although the risk of embolism after preoperative ICA is low, it should be carefully weighed against the estimated risk of CAD-related perioperative complications. CCTA can serve as a gatekeeper for ICA in most patients with acute aortic IE.

Abstract
OBJECTIVES To assess the benefit/risk ratio to perform a coronary angiography (CA) before surgery for infective endocarditis (IE). METHODS We conducted a single-center prospective registry including 272 patients with acute IE intended for surgery and compared patients who underwent a preoperative CA (n = 160) with those who did not (n = 112). A meta-analysis of 3 observational studies was also conducted and included 551 patients: 342 who underwent a CA and 209 who did not. RESULTS In our registry, combined bypass surgery (CABG) was performed in 17% of the patients with preoperative CA. At 2 years, the rate of the primary composite end point (all-cause death, new systemic embolism, stroke, new hemodialysis) was similar in the CA (38%) and no-CA (37%) groups. In-hospital and 2-year individual end points were all similar between groups. There were only 2 episodes of systemic embolism after CA and only one possibly related to a vegetation dislodgement. In the meta-analysis, combined CABG was performed in 18% of the patients with preoperative CA. All-cause death was similar in both groups: odds ratio, 0.98 [0.62-1.53], P = .92. Only 5 cases of systemic embolism possibly related to a vegetation dislodgement were reported. New hemodialysis was numerically more frequent in the CA group: odds ratio, 1.68 [0.79-3.58] (18% vs 14%, P = .18). CONCLUSIONS In daily practice, two-thirds of the patients with acute IE who required surgery have a preoperative CA leading to a combined CABG in 18% of the patients. Our results suggest that to perform a preoperative CA in this context is not associated with improved prognosis.

Abstract
Background This study aims to evaluate the surgical outcomes of prosthetic valve endocarditis. Methods A total of 21 patients (6 males, 15 females; mean age 58.9±12.6 years; range, 33 to 79 years) who were surgically treated for prosthetic valve endocarditis between January 2013 and January 2018 were retrospectively analyzed. Surgical indications included persistent fever for more than seven days after antibiotherapy, congestive heart failure refractory to medical treatment, vegetations larger than 1 cm on echocardiography, the presence of fungal endocarditis, severe valvular leak and valvular dysfunction, and staphylococcal prosthetic valve endocarditis. Results Five patients had previous aortic valve replacement and three of the aortic prostheses were re-replaced. Two patients had coexisting native mitral valve endocarditis and double valve replacement was done. Thirteen patients had previous mitral valve replacement and 12 of the mitral prostheses were re-replaced. One patient had coexisting native aortic valve endocarditis and double valve re-replacement was done. Three patients had previous aortic valve replacement + mitral valve replacement. Mitral valve endocarditis was diagnosed in two patients and these patients had only mitral valve re-replacement. The other patient had double valve endocarditis, and double valve replacement was done. The mean time from the first operation to the development of endocarditis was 7.3±5.7 years. Of five lost patients, two died from multiple organ failure, one from low cardiac output, one from pneumonia, and one from respiratory failure. Conclusion Radical resection of the infected tissues is critical to achieve favorable surgical outcomes. Single valve replacement of the infected valve may be preferred in patients having previous double valve replacement. Mechanical valves or bioprostheses can be used for re-replacement procedures.

Abstract
OBJECTIVES The aim of this study was to investigate the value of electrocardiogram (ECG)-gated computed tomography (CT) in the surgical decision-making and preoperative evaluation in patients with aortic prosthetic valve endocarditis (PVE). METHODS Sixty-eight prosthetic valves in 67 patients with aortic PVE were prospectively evaluated with ECG-gated CT and transoesophageal echocardiography (TEE). Imaging findings considered indications for surgery were as follows: (i) abscess/pseudoaneurysm formation; (ii) prosthetic valve dehiscence; (iii) valve destruction with valvular regurgitation; (iv) large vegetations (>1.5 cm). The coronary arteries were evaluated with ECG-gated CT. Clinical data including surgical reports and mortality data were collected. RESULTS Fifty-eight of 68 cases had indication for surgery based on imaging findings (ECG-gated CT/TEE). In 8 of these cases (14%), there was indication for surgery based on CT but not on TEE findings (all had perivalvular pseudoaneurysms). In 11 cases (19%), there was indication for surgery based on TEE but not on CT findings [non-drained abscess (n = 5), prosthetic valve dehiscence (n = 4), large vegetation (n = 1), valve destruction (n = 1)]. In 31 of 32 patients with indication for preoperative coronary angiography, ECG-gated CT coronary angiography was diagnostic. In 1 patient, ECG-gated CT coronary angiography was inconclusive and invasive coronary angiography was performed. CONCLUSIONS In patients with aortic PVE, ECG-gated CT provides additional information over TEE regarding perivalvular extension of infection, which can influence surgical decision-making. Furthermore, ECG-gated CT provides a non-invasive coronary angiogram and can in most cases replace invasive coronary angiography in the preoperative evaluation.

Abstract
Background and aims The introduction of Duke’s criteria and the improvement of imaging methods has lead to an earlier and a more accurate diagnosis of infectious endocarditis (IE). The options for the best therapeutic approach and the timing of surgery are still a matter of debate and require a close colaboration between the cardiologist, the infectionist and the cardiac surgeon. Methods We undertook a retrospective, descriptive study, spanning over a period of five years (from January 1st, 2007 to December 31st, 2012), on 100 patients who underwent surgery for native valve infectious endocarditis in our unit. Results The patients’ age varied between 13 and 77 years (with a mean of 54 years), of which 85 were males (85%). The main microorganisms responsible for IE were: Streptococcus Spp. (21 cases – 21%), Staphylococcus Spp. (15 cases – 15%), and Enterococcus Spp. (9 cases – 9%). The potential source of infection was identified in 26 patients (26%), with most cases being in the dental area (16 cases – 16%). The lesions caused by IE were situated in the left heart in 96 patients (96%), mostly on the aortic valve (50 cases – 50%). In most cases (82%) we found preexisting endocardial lesions which predisposed to the development of IE, most of them being degenerative valvular lesions (38 cases – 38%). We performed the following surgical procedures: surgery on a single valve - aortic valve replacement (40 cases), mitral valve replacement (19 cases), mitral valve repair (1 case), surgery on more than one valve – mitral and aortic valve replacement (20 cases), aortic and tricuspid valve replacement (1 case), aortic valve replacement with a mechanical valve associated with mitral valve repair (5 cases), aortic valve replacement with a biological valve associated with mitral valve repair (2 cases), and mitral valve replacement with a mechanical valve combined with De Vega procedure on the tricuspid valve (1 case). In 5 patients (5%) the bacteriological examination of valve pieces excised during surgery was positive. In 3 cases it matched the germ identified in the hemocultures, and in 2 cases it evidenced another bacterium. Conclusion The overall mortality of 5% is well between the limits presented in literature, being higher (30%) in patients who required emergency surgery. For the patients who return into our clinic with prosthetic valve endocarditis, the mortality after surgery was even higher (50%).

Abstract
The purpose of this study was to describe the application of coronary computed tomography angiography (CCTA) in evaluation of patients with history of intravenous drug use (IDU). An IRB approved retrospective review was performed of all patients who had a prior history of IDU and presenting with endocarditis who had undergone CCTA. Demographic characteristics and cardiovascular risk factors were collected. In addition, we reviewed CCTA reports for dosimetric parameters, calcium score, and atherosclerotic burden. There were 32 patients (25 males) included in this study with a mean age of 38 ± 10.8 years. The average BMI for the study group was 26.5 ± 4.9. 44 % of patients had evidence of atherosclerotic disease on coronary CTA. Mean calcium score was 175 ± 487. Median total exam effective dose was 4.8 mSv (range: 3.3-7.3 mSv). In spite of their relatively young age and BMI at the upper limits of normal, patients with history of IDU have atherosclerosis and coronary CTA can be utilized to screen these patients and may be helpful for risk stratification prior to noncoronary surgical procedures. Given the recent rise in IDU, this may become a growing indication for CCTA.

Abstract
This report describes a 42-year-old man with a history of lymphoma who is admitted with symptoms of chest pain, ST elevation changes, and elevated troponins. Immediate bedside echocardiographic evaluation led to an aborted urgent coronary angiography and a diagnosis of presumed endocarditis. Transesophageal echocardiography (TTE) subsequently revealed an aortic noncoronary cusp aneurysm masking as vegetation. The rapid assessment by TTE and transesophageal echocardiogram prevented an alternate course for this patient's management. We reviewed the necessity of heart catheterization in patients with significantly elevated troponins, pericarditis symptoms, and the rare sighting of aortic valve cusp aneurysms.

Abstract
Intracellular action potentials (IAPs) produced by short fibres in response to their electrical stimulation were analysed. IAPs were calculated on the basis of the Hodgkin-Huxley (1952) model by the method described by Joyner et al. (1978). Principal differences were found in processes of activation of short (semilength L less than 5 lambda) and long fibres under near-threshold stimulation. The shorter the fibre, the lower was the threshold value (Ithr). Dependence of the latency on the stimulus strength (Ist) was substantially non-linear and was affected by the fibre length. Both fibre length and stimulus strength influenced the IAP amplitude, the instantaneous propagation velocity (IPV) and the site of the first origin of the IAP (and, consequently, excitability of the short fibre membrane). With L less than or equal to 2 lambda and Ithr less than or equal to Ist less than or equal to 1.1Ithr, IPV could reach either very high values (so that all the fibre membrane fired practically simultaneously) or even negative values. The latter corresponded to the first origin of the propagated IAP, not at the site of stimulation but at the fibre termination or at a midpoint. The characters of all the above dependencies were unchanged irrespective of the manner of approaching threshold (variation of stimulus duration or its strength). Reasons for differences in processes of activation of short and long fibres are discussed in terms of electrical load and latency. Applications of the results to explain an increased jitter, velocity recovery function and velocity-diameter relationship are also discussed.
