ABSTRACT
Background and Objectives. Distinct pressure curve differences exist between akinetic (A-LVA) and dyskinetic (D-LVA) aneurysms. In D-LVA, left ventricular (LV) ejection pressure decreases relative to the aneurysm size, whereas A-LVA does not impact pressure curves, indicating that the decrease in stroke volume (SV) and cardiac output is proportional to the size of dyskinesia. This study aimed to assess the frequency of A-LVA and D-LVA, determine aneurysm size parameters (volume and surface area), and evaluate predictive parameters using echocardiography in A-LVA and D-LVA. Furthermore, it aimed to compare individual echocardiographic parameters, according to ejection fraction (EF) and SV, with hemodynamic events shown in experimental models of A-LVA and D-LVA and their significance in everyday clinical practice. Materials and Methods. This clinical study included patients with post-infarction left ventricular aneurysm (LVA) admitted to the cardiovascular institute ''Dedinje", Serbia. Echocardiographic volume and surface area of LV and LVA were determined (by the area-length method) along with EF (by Simpson's method). Results. A-LVA was present in 62.9% of patients, while D-LVA was present in 37.1%. Patients with D-LVA had significantly higher systolic aneurysm volume (LVAVs) (94.07 ± 74.66 vs. 51.54 ± 53.09, p = 0.009), systolic aneurysm surface area (LVAAs) (23.22 ± 11.73 vs. 16.41 ± 8.58, p = 0.018), and end-systolic left ventricular surface areas (LVESA) (50.79 ± 13.33 vs. 42.76 ± 14.11, p = 0.045) compared to patients with A-LVA. The ratio of LVA volume to LV volume was higher in the D-LVA in systole (LVAVs/LVESV). The end-diastolic volume of LV (LVEDV) and end-systolic volume of LV (LVESV) did not significantly differ between D-LVA and A-LVA. EF (21.25 ± 11.92 vs. 28.18 ± 11.91, p = 0.044) was significantly lower among patients with D-LVA. Conclusions. Differentiating between A-LVA and D-LVA using echocardiography is crucial since D-LVA causes greater hemodynamic disturbances in LV function, and thus surgical resection of the aneurysm or LV reconstruction must have a positive effect regardless of myocardial revascularization surgery.

Cholesterol granuloma is a rare entity, which can develop in many regions of the body, accounting at most 1% of all mediastinal tumors. Etiology of this granuloma is still not clearly understood. The gold standard choice of treatment for cholesterol granuloma is total surgical resection. Symptomatic mediastinum granuloma can be easily diagnosed, but if mass effect is not evident then diagnosis of this tumor is really challenging. We present a rare case of huge cholesterol granuloma in the anterior mediastinum of the patient who underwent on elective coronary artery graft bypass surgery.
ABSTRACT
Diagnosing intracardiac masses poses a complex, multimodal challenge. We present the case of a 72-year-old woman with a history of rheumatic fever leading to mitral stenosis and a previous mitral valve commissurotomy who reported fatigue, weakness, and palpitations over the past three months. Echocardiography revealed a tumor (53 × 40 mm) in the enlarged left atrium, attached by a wide base to the left atrium wall, exhibiting variable densities. Computerized tomography identified a heterodense mass (53 × 46 × 37 mm) with similar attachments. Angiography showed two branches from the circumflex artery intricately associated with the mass. Despite unsuccessful embolization of the mass' blood supply, surgical intervention including mitral valve replacement, tricuspid valve annuloplasty, and tumor removal was pursued. Pathohistological analysis confirmed the mass as a thrombus. During the postoperative follow-up, the patient presented with no complaints. Follow-up echocardiography indicated the normal function of the mechanical mitral valve prosthesis and the absence of intracardiac masses. While it remains unknown whether this neovascularization is specific to patients with severe mitral valve disease, this case highlights the diagnostic challenges of differentiating between thrombi and tumors in the context of mitral valve disease. It illustrates the critical role of multimodal imaging in elucidating the anatomical and functional relationships within the heart, thereby guiding accurate diagnosis and effective treatment.
ABSTRACT
Idiopathic dilatation of the right atrium is a rare condition with an unknown etiology. It is characterized by a significant enlargement of the right atrium without the presence of other valvopathies, intracardiac shunts, or pulmonary hypertension. This report presents the case of a 50-year-old woman with a significantly enlarged right atrium that was identified at birth; however, a definitive diagnosis was made later in life. The patient did not have any genetic diseases. Through the help of regular follow-up, anticoagulant therapy, previous radio-frequency ablation, and antiarrhythmic medications, she was able to carry a pregnancy to full term and live a regular life.

The 12-lead electrocardiogram (ECG) is a first-line diagnostic tool for patients with cardiac symptoms. As observed during the COVID-19 pandemic, the ECG is essential to the initial patient evaluation. The novel KardioPal three-lead-based ECG reconstructive technology provides a potential alternative to a standard ECG, reducing the response time and cost of treatment and improving patient comfort. Our study aimed to evaluate the diagnostic accuracy of a reconstructed 12-lead ECG obtained by the KardioPal technology, comparing it with the standard 12-lead ECG, and to assess the feasibility and time required to obtain a reconstructed ECG in a real-life scenario. A prospective, nonrandomized, single-center, adjudicator-blinded trial was conducted on 102 patients during the COVID-19 pandemic at the Dedinje Cardiovascular Institute in Belgrade. The KardioPal system demonstrated a high feasibility rate (99%), with high specificity (96.3%), sensitivity (95.8%), and diagnostic accuracy (96.1%) for obtaining clinically relevant matching of reconstructed 12-lead compared to the standard 12-lead ECG recording. This novel technology provided a significant reduction in ECG acquisition time and the need for personnel and space for obtaining ECG recordings, thereby reducing the risk of viral transmission and the burden on an already overwhelmed healthcare system such as the one experienced during the COVID-19 pandemic.
ABSTRACT
The successful outcome of a cardiac surgery procedure is significantly dependent on the management of cardiopulmonary bypass (CPB). Even if a cardiac operation is technically well-conducted, a patient may suffer CPB-related complications that could result in severe comorbidities, reduced quality of life, or even death. However, the role of clinical perfusionists in perioperative patient care, which is critical, is often overlooked. Therefore, the European Association for Cardio-Thoracic Surgery (EACTS), the European Association of Cardiothoracic Anaesthesiology (EACTA), and the European Board of Cardiovascular Perfusion (EBCP) have agreed to develop joint clinical practice guidelines (CPGs) for CPB due to its significant impact on patient care and significant variations in practice patterns between countries. The European guidelines, based on the EACTS standardized framework for the development of CPGs, cover the entire spectrum of CPB management in adult cardiac surgery. This includes training and education of clinical perfusionists, machine hardware, disposables, preparation for initiation of CPB, a complete set of procedures during CPB to help maintain end-organ function and anticoagulation, weaning from CPB, and the gaps in evidence and future research directions. This comprehensive coverage ensures that all aspects of CPB management are addressed, providing clinicians with a standardized approach to CPB management based on the latest evidence and best practices. To ensure better integration of these evidence-based recommendations into daily practice, this review aims to provide a general understanding of guideline development and an overview of essential treatment recommendations for CPB management.
ABSTRACT
Assessment of the functional significance of coronary artery stenosis using invasive measurement of fractional flow reserve (FFR) or non-hyperemic indices has been shown to be safe and effective in making clinical decisions on whether to perform percutaneous coronary intervention (PCI). Despite strong evidence from clinical trials, utilization of these techniques is still relatively low worldwide. This may be to some extent attributed to factors that are inherent to invasive measurements like prolongation of the procedure, side effects of drugs that induce hyperemia, additional steps that the operator should perform, the possibility to damage the vessel with the wire, and additional costs. During the last few years, there was a growing interest in the non-invasive assessment of coronary artery lesions, which may provide interventionalist with important physiological information regarding lesion severity and overcome some of the limitations. Several dedicated software solutions are available on the market that could provide an estimation of FFR using 3D reconstruction of the interrogated vessel derived from two separated angiographic projections taken during diagnostic coronary angiography. Furthermore, some of them use data about aortic pressure and frame count to more accurately calculate pressure drop (and FFR). The ideal non-invasive system should be integrated into the workflow of the cath lab and performed online (during the diagnostic procedure), thereby not prolonging procedural time significantly, and giving the operator additional information like vessel size, lesion length, and possible post-PCI FFR value. Following the development of these technologies, they were all evaluated in clinical trials where good correlation and agreement with invasive FFR (considered the gold standard) were demonstrated. Currently, only one trial (FAVOR III China) with clinical outcomes was completed and demonstrated that QFR-guided PCI may provide better results at 1-year follow-up as compared to the angiography-guided approach. We are awaiting the results of a few other trials with clinical outcomes that test the performance of these indices in guiding PCI against either FFR or angiography-based approach, in various clinical settings. Herein we will present an overview of the currently available data, a critical review of the major clinical trials, and further directions of development for the five most widely available non-invasive indices: QFR, vFFR, FFRangio, caFFR, and AccuFFRangio.
ABSTRACT
Background and Objectives: The saphenous vein is one of the most common used grafts (SVG) for surgical revascularization. The mechanism of the SVGs occlusion is still unknown. Surgical preparation techniques have an important role in the early and late graft occlusion. Our study analyzed the influence of the three different surgical techniques on the histological and immunohistochemical characteristics of the vein grafts. Methods: Between June 2019 and December 2020, 83 patients who underwent surgical revascularization were prospectively randomly assigned to one of the three groups, according to saphenous vein graft harvesting (conventional (CVH), no-touch (NT) and endoscopic (EVH)) technique. The vein graft samples were sent on the histological (hematoxylin-eosin staining) and immunohistochemical (CD31, Factor VIII, Caveolin and eNOS) examinations. Results: The CVH, NT, and EVH groups included 27 patients (mean age 67.66 ± 5.6), 31 patients (mean age 66.5 ± 7.4) and 25 patients (mean age 66 ± 5.5), respectively. Hematoxylin-eosin staining revealed a lower grade of microstructural vein damage in the NT group (2, IQR 1-2) in comparison with CVH and EVH (3, IQR 2-4), (4, IQR 2-4) respectively (p < 0.001). Immunohistochemical examination revealed a high grade of staining in the NT group compared to the CVH and EVH group (CD 31 antibody p = 0.02, FVIII, p < 0.001, Caveolin, p = 0.001, and eNOS, p = 0.003). Conclusion: The best preservation of the structural vein integrity was in the NT group, while the lowest rate of leg wound complication was in the EVH group. These facts increase the interest in developing and implementing the endoscopic no-touch technique.

BACKGROUND: The optimal treatment strategy for patients with severe carotid artery disease undergoing coronary artery bypass grafting is still problematic. The important question is whether it is necessary to treat significant carotid disease in patients who have undergone coronary artery bypass grafting. This study analyzed short- and midterm results after same-day carotid artery stenting and coronary artery bypass grafting. METHODS: From 2013 to 2020, a total of 69 patients were enrolled in the study. Same-day carotid artery stenting and coronary artery bypass grafting were performed in all patients. The study's primary end points were the evaluation rate of stroke, myocardial infarction, and death within short- and midterm periods after the procedures. RESULTS: The 30-day mortality was 0%. The occurrences of perioperative adverse events, namely stroke, myocardial infarction, and transient ischemic attack, were 1 (1.4%), 1 (1.4%), and 4 (5.8%), respectively. Mean (IQR) follow-up time was 28 (IQR, 17-43) months. Six (8.8%) patients died during this period. Fatal stroke was registered in 2 cases, and 1 patient experienced a disabling stroke with a fatal outcome. The other 3 patients died because of chronic renal disease, a traffic accident, and for an unknown reason, respectively. Midterm survival in the group was 91.2%. CONCLUSION: The study showed that same-day carotid artery stenting and coronary artery bypass grafting for concomitant carotid and coronary disease treatment could be a promising and feasible therapeutic strategy.

BACKGROUND: The revascularisation strategy for concomitant carotid and coronary disease is unknown. Simultaneous or stage coronary artery stenting and carotid endarterectomy are the most common revascularisation approach in the CABG population. This study aimed to evaluate long-term results after simultaneous carotid artery stenting or carotid endarterectomy in patients who underwent coronary artery bypass surgery. METHODS: This is a prospective cohort non-randomised single-institution study. During the period from 2012 to 2015, sixty consecutive patients (65.9 ± 7.41 mean) underwent simultaneous carotid artery stenting and coronary artery bypass surgery (n = 30) or simultaneous carotid endarterectomy and coronary artery bypass surgery (n = 30). The primary endpoints were short- and long-term rates of adverse events (transient ischemic attack, stroke, myocardial infarction, and death). The mean follow-up was 62.05 ± 11.12 months. RESULTS: In-hospital mortality was insignificantly higher in the carotid endarterectomy, and coronary artery bypass surgery group (6.6% vs. 0%), the rate of stroke and myocardial infarction was similar (13.3% and 0% in the carotid endarterectomy and coronary artery bypass surgery group vs. 6.6% and 3.3% in the carotid artery stenting and coronary artery bypass surgery group, respectively). The intensive care unit readmission was significantly higher in the surgical revascularisation approach; it was an independent predictor of hospital mortality. The overall mortality during the follow-up period was 14.28% in both groups. Freedom of the composite adverse outcomes (stroke, myocardial infarction, and death) was 78.55%. CONCLUSION: Comparing two revascularisation strategies is not straightforward due to different anatomical indications for carotid artery stenting and endarterectomy. We consider that each technique has an essential role in carotid revascularisation. Good selection of patients, according to indications, contributes to satisfactory short- and long-term results.

Introduction: Severe aortic stenosis, a highly-common valve disease in the elderly, has a poor prognosis if left untreated. To address the concern of effective procedures for severe aortic stenosis, a systematic TAVI program was established at the Dedinje Cardiovascular Institute (Belgrade, Serbia). Methods: Our cohort was composed of 56 patients (74±15 years old). The mean logistic EuroScore was 10.17%; the mean Society of Thoracic Surgeons score was 3.22%. One third of the patients were categorized as class III or IV of the New York Heart Association (NYHA). The valves selected for use were either self-expandable or balloon expandable (Evolut R, Medtronic; Acurate Neo, Boston Scientific and Myval, Meril). The choice of valve type was made by the Institute's Structural Heart Team, in accordance with the patient's native aortic valve, size and calcification of ilio-femoral vessels, as well as the need for alternative access. TAVI procedure was conducted according to current guidelines provided by the European Society of Cardiology. Results: The procedure success rate was 100%. Trans-femoral approach was achieved in 100% of patients; percutaneously in 87.5%, while a surgical cut was necessary in 12.5%. No patient showed moderate or severe aortic regurgitation after the procedure, although trace or mild regurgitation was recorded in 30.3%. Permanent pacemaker was implanted in one patient (1.78%), contrast induced acute kidney injury occured in one patient (1.78%), no stroke was recorded, and three pseudo-aneurysms which required surgical intervention occurred. Three patients required blood transfusions (5.33%). A 30-day all-cause mortality rate was 1.78%. Conclusion: The Dedinje Cardiovascular Institute spearheaded all efforts to establish a TAVI program in Serbia. Our initial TAVI results are promising, encouraging, and comparable with the results of previous large randomized trials. This initial experience opens the door for further development with a goal of our Institute to become a high-volume TAVI center.
ABSTRACT
Background: The purpose of this study was to compare home and office BP in the adjustment of antihypertensive treatment. Methods: This study was an open, prospective, noninterventional, multicenter clinical trial that occurred between July 2019 and February 2020, in 34 cities in the territory of the Republic of Serbia, which monitored 1581 participants for 6 months. Depending on the used blood pressure monitoring method used, all patients were divided into control (office BP monitoring) and experimental (home BP telemonitoring) groups. We collected anamnestic data and data about systolic blood pressure (SP), in mmHg, diastolic blood pressure (DP), in mmHg, and heart rate (HR), in beats/minute, from all patients. Results: SP values were significantly different at baseline, and at the second, third, and fourth visits between the two tested groups. Home and office BP decreased significantly (p < 0.000) during the 6-month follow-up. We observed a statistically significant influence of the presence of diabetes mellitus and dyslipidemia on the dynamics of differences between SP monitoring values. Conclusions: Our study suggests that novel technologies in BP monitoring can be excellent alternatives for BP assessment in hypertensive patients with other cardiovascular risk factors such as diabetes and dyslipidemia.
ABSTRACT
OBJECTIVES: The present study aimed to identify significant causes of readmission within 30 days following coronary artery bypass graft (CABG) surgery and compare readmission incidence related to surgical site infections (SSIs) before and after implementing international recommendations for antibiotic prophylaxis. METHODS: We analyzed 2,225 CABG patients who received either guideline-directed antibiotic prophylaxis (GDAP = 568) or institutional antibiotic prophylaxis (non-GDAP = 1,657) between January 2017 and December 2019. The primary outcome was a composite of sternal wound infection (SWI) or harvest SWI. Secondary outcomes consisted of the individual components of composite end point, the incidence of in-hospital SSIs, and prolonged postoperative length of hospital stay (LOS) (>7 days). Propensity matching was used to select pairs for final comparison. RESULTS: Before implementing GDAP, the most frequent reason for readmission were SSIs, causing 58.2% of all readmissions within 30 days. Of 429 matched pairs, 48 patients in the GDAP group and 67 patients in the non-GDAP group were readmitted to a hospital within 30 days for any cause (11.2 vs. 15.6%, p = 0.048). We found a decreased readmission incidence for reasons related to SSIs, although these differences did not reach statistical significance (7.4 vs. 10.0%, p = 0.069). Adherence to GDAP was associated with reduced in-hospital risks of SSIs and prolonged postoperative LOS (19.6 vs. 26.6%, p = 0.015). CONCLUSIONS: In this contemporary clinical practice study, the adherence to GDAP was an insufficient measure to decrease rehospitalization due to SSIs. The present findings warrant further investigation on factors that may contribute to SSIs development after hospital discharge.

This study introduces the pulmonary vein isolation outcome degree (PVIOD) as a new semiquantitative measure for the efficacy of atrial fibrillation (AF) catheter ablation and reports the determination of predictors associated with PVIOD. The median follow-up periods of 117 patients after the first and last ablation were, respectively, 82 (IQR 15) and 72 (IQR 30) months. PVIOD 1 included 32.5% of patients, those with successful single pulmonary vein isolation (PVI); PVIOD 2 included 29.1% of subjects, those with success after multiple procedures; PVIOD 3 comprised 14.5% of patients, those with clinical success; and PVIOD 4 included 23.9% of cases, those with procedural and clinical failure. In the multivariate ordinal logistic regression analysis, PVIOD 1-4 were independently associated with longstanding persistent AF with paroxysmal AF as the referent category (odds ratio (OR), 3.5; 95% confidence interval (95% CI), 1.1-10.7 (p = 0.031)), left atrial (LA) diameter (OR, 1.2; 95% CI, 1.1-1.3 (p = 0.001)) and left ventricular ejection fraction (LVEF) (OR, 0.9; 95% CI, 0.86-1.0 (p = 0.038)). LA size > 41 mm, LVEF ≤ 50% and longstanding persistent AF are strong predictors of AF recurrence. PVIOD 1-4 offer the most exact long-term prognosis of PVI. The purpose of the present article is to expand the quantitative measure of procedural success in the medical and biological fields.
ABSTRACT
INTRODUCTION: The estimated infection rate after permanent endocardial lead implantation is between 1% and 2%. Pacemaker lead endocarditis is treated with total removal of the infected device and proper antibiotics. In this case report, we present a patient with delayed diagnosis and treatment due to the COVID-19 outbreak. CASE REPORT: An 88-year-old, pacemaker dependent woman with diagnosed pacemaker pocket infection was admitted to the University Cardiovascular institute. The patient had a prolonged follow-up time due to the COVID-19 outbreak. She missed her routine checkup and came to her local hospital when the generator had already protruded completely, to the point where she held it in her own hand. Transthoracic echocardiogram showed possible vegetations on the lead. Transesophageal echocardiography was not performed due to the COVID-19 pandemic. On the day after the admission the patient underwent transvenous removal of the pacemaker lead using a 9 French gauge rotational extraction sheathe (Cook Medical). The extracted lead was covered in a thin layer of vegetations. Further follow-ups showed good recovery with no complications. CONCLUSIONS: A case showing delayed treatment of pacemaker pocket infection, due to delayed follow-up time during the COVID-19 pandemic. This patient underwent successful transvenous removal of the infected pacemaker lead, along with adequate antibiotic therapy, which has proven to be the most effective method of treating cardiac device-related endocarditis.

The patient was admitted for urgent coronary angiography following an acute anterior ST segment elevation myocardial reinfarction (STEMI) caused by acute stent thrombosis. A stent had been implanted 10 days prior to the reinfarction for an acute anterior STEMI. However, the patient had stopped taking ticagrelor post-discharge. Primary percutaneous coronary intervention of the left anterior descending artery was performed. Subsequently, due to a high C-reactive protein (CRP) level, 3 CRP apheresis sessions were performed, with the first session starting 12 h after the onset of symptoms. A significant drop in CRP was noted after each apheresis. The post-procedural course was uneventful.

OBJECTIVES: The pandemic of coronavirus associated disease (COVID-19) placed the health care workers at high risk. We investigated clinical and treatment characteristics of infected medical professionals in a cardiovascular hospital. METHODS: The study was retrospective, conducted in tertiary cardiovascular hospital and included employees with confirmed coronavirus infection. They filled out a questionnaire about health status, symptoms, admission to hospital and treatment. The vaccination status against tuberculosis, hepatitis B and seasonal influenza was assessed. Pneumonia was defined as CT finding of ground glass opacifications (GGO) with consolidations typical for COVID-19. RESULTS: The study included 107 confirmed cases of COVID - 19 out of 726 employees (15%). Most of the infected were from cardiac surgery department (74/107, 69%). Substantial number of employees did not have any symptoms [31 (28.9%)] and 38 patients (35.5%) were admitted to hospital. The average hospital length of stay was 8.1 ± 5.6 days. Seventy-five of 107 (70.1%) received seasonal influenza vaccine. Pneumonia with CT features of GGO and consolidation occurred in 25/107 (23.4%) patients of which 14/107 (13.1%) had bilateral involvement. In multivariate logistic regression analysis including recognized characteristics associated with worse outcomes in COVID-19 (obesity, diabetes mellitus, coronary artery disease, cerebrovascular disease, current smoking, heart failure, influenza immunization), only influenza immunization remained an independent predictor of occurrence of bilateral pneumonia (OR 0.207; 95%CI[0.050 - 0.847]; p = 0.029). CONCLUSIONS: The association of influenza immunization and less aggressive form of pneumonia might provide a finding that supports the institution of preventive measures that can be beneficial in reduction of global coronavirus burden.

INTRODUCTION: Results of currently available trials have shown divergent outcomes in diabetic patients undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Current guidelines do not recommend PCI in patients with diabetes and a SYNTAX score ≥ 23. AIM: To compare all-cause 4-year mortality after revascularization for complex coronary artery disease (CAD) in diabetics. MATERIAL AND METHODS: The study group comprised consecutive patients with three-vessel CAD and/or unprotected left main CAD (≥ 50% diameter stenosis) without major hemodynamic instability, who were treated in two institutions with PCI or referred for CABG. RESULTS: Out of 342 diabetics, 177 patients underwent PCI and 165 patients were referred for CABG. The incidence of all-cause death was different between diabetics treated with PCI or CABG at 4 years (16/177, 9.0% vs. 26/165, 15.8%, respectively, p = 0.03). The difference was not evident in non-diabetics (PCI: 41/450, 9.1% vs. CABG: 19/249, 7.6%, p = 0.173). In diabetics, there was a higher incidence of all-cause mortality in PCI patients with intermediate-high (≥ 23) SYNTAX scores compared with those with low (0-22) SYNTAX scores (10/56, 17.9% vs. 6/121, 5.0%, respectively, p < 0.01). On the other hand, diabetics who underwent CABG showed similar mortality rates irrespective of the SYNTAX scores (SYNTAX 0-22: 3/29, 10.3%; SYNTAX ≥ 23: 23/136, 11.9%, p = 0.46). In the subgroup analysis, there was no interaction according to presence or absence of left main CAD (p for interaction = 0.12) as well as according to diabetes status (p for interaction = 0.38), whereas gender and SYNTAX scores were differentiators between PCI and CABG with a p for interaction < 0.1. CONCLUSIONS: Our analysis supports recent evidence that diabetes is not a differentiator between PCI and CABG.
ABSTRACT
This article reviews the context and evidence of recent myocardial revascularization trials on PCI versus CABG with particular emphasis on patient selection and treatment of surgical patients. Moreover, one of our intended purposes is to identify the values underpinning the integrated care model, which incorporates decision to proceed with surgical myocardial revascularization in conjunction with established pillars of the use of optimal surgical techniques, and aggressive risk-factor modification through guideline-directed pharmacological therapies and lifestyle modifications.

Lyme endocarditis is extremely rare manifestation of Lyme disease. The clinical manifestations of Lyme endocarditis are non-specific and can be very challenging diagnosis to make when it is the only manifestation of the disease. Until now, only a few cases where reported. Physicians should keep in mind the possibility of borrelial etiology of endocarditis in endemic areas. Appropriate valve tissue sample should be sent for histopathology, culture, and PCR especially in case of endocarditis of unknown origin PCR on heart valve samples is recommended. With more frequent PCR, Borrelia spp. may be increasingly found as a cause of infective endocarditis. Prompt diagnosis and treatment of Lyme carditis may prevent surgical treatment and pacemaker implantations. Due to climate change and global warming Lyme disease is a growing problem. Rising number of Lyme disease cases we can expect and rising number of Lyme endocarditis.
