A challenging case report of IgG4-related systemic disease involving the heart and retroperitoneum with a literature review of similar heart lesions.

The IgG4-related disease is a distinct, steroid-responsive fibro-inflammatory disorder of unknown etiology. This multiorgan disease is characterized by tumefactive lesions that contain rich infiltrations of IgG4-positive plasma cells, with the pancreas, and the salivary and lacrimal glands being the main involved. The more common cardiovascular involvements include inflammatory peri-aortitis, coronary arteritis, and pericarditis. Intra-cardiac tumefactive lesions are rarely reported. Herein, we describe a challenging case of IgG4-related disease with a long-time lag between initiation of symptoms to proper diagnosis with biopsy-proven cardiac and retroperitoneal and possible pituitary gland involvement. Concerning the rarity of the cardiac lesion in our case, we conducted a literature review of similar case reports.

Postinfarction intramyocardial dissection, an interesting case report and systematic review.

Intramyocardial dissection (IMD) with ventricular septal rupture (VSR) following myocardial infarction (MI) is a rare subacute form of cardiac rupture. The evidence available in this regard is scarce. We aimed to share our experience and conduct a systematic review of previous cases. We searched the literature and performed a systematic review of previous cases. A total of 37 cases of IMD with VSR were included (1 our original and 36 literature cases). Mean age was 68 ± 8 years and 20 (54.1%) patients were male. Anterior and inferior MI were observed in 14 (37.8%) and 23 (62.2%) cases, respectively. The dissected area was the septum, RV, both septum and RV, or LV apex in 21 (56.8%), 9 (24.3%), 5 (13.5%), and 2 (5.4%), respectively. Apicoseptal and inferoseptal VSR were observed in 15 (40.5%) and 22 (59.5%) cases, respectively. At least one occluded artery was observed in 29 (90.6%) of cases. Reperfusion therapy was done for 15 (40.5%) cases before the VSR occurred. Surgery, percutaneous, and medical therapy were done for 26 (70.3%), 3 (8.1%), and 7 (18.9%) cases, respectively. The mortality rate was significantly higher in the medical versus surgical-treated group (85.7% versus 42.3%, P = .027). There was a trend to higher mortality in the group with dissection of both septum and RV (P = .15). We concluded that echocardiography has a critical role in diagnosing this complication. Surgery is mandatory in IMD with VSR.

Aortic valve cusp aneurysm as a result of blood culture-negative infective endocarditis, interesting echocardiographic and surgical images.

Compared to mitral valve aneurysms, aortic valve (AV) aneurysm is a more rare and serious complication of infective endocarditis (IE). Early surgical intervention and valve replacement are required in order to prevent further complications such as embolization and rupture of aneurysm. We described a case of severe aortic regurgitation (AR) as a result of an aortic valve aneurysm in a patient with history of end-stage renal disease (ESRD) in whom the hemodialysis catheter had not been changed for a year.

Retained entrapped coronary stent appearing like an aortic flap.

Entrapment of coronary angioplasty hardware is a rare but serious complication of coronary interventions which may be managed percutaneously or surgically. We described a case of an entrapped coronary stent in a patient with a history of failed coronary intervention with no documents available. In transesophageal echocardiography, there was a linear echo density in the ascending aorta stuck in the right coronary artery resembling a dissection flap but based on the history of failed coronary intervention, this odd structure was supposed to be a retained angioplasty device. The patient underwent surgical removal of the entrapped device which was a fractured stent.

Ruptured mitral valve aneurysm: A devastating complication of aortic valve endocarditis.

Mitral valve aneurysm is a rare clinical entity that is mostly resulted from infective endocarditis, in particular, aortic valve endocarditis. Once mitral valve aneurysm ruptures and severe mitral regurgitation and hemodynamic instability develop, prompt surgery should be considered. Here we report a patient with ruptured mitral valve aneurysm associated with native aortic valve endocarditis that was improved after a successful mitral and aortic valve replacement surgery associated with antibiotic therapy for 6 weeks.

Right ventricular myxoma originating from a papillary muscle: a case report.

Very few cases of ventricular myxoma originate from a papillary muscle. Patients with a cardiac myxoma and a history of colorectal carcinoma are also rare. Here, we present a case of an extremely large right ventricular myxoma that originated from the posteromedial papillary muscle in a patient with a history of colorectal carcinoma.

Novel Echocardiographic Indices as Predictors of Immediate Recurrence after Undersized Ring Annuloplasty for Ischemic Mitral Regurgitation.

BACKGROUND AND AIM: Ischemic mitral regurgitation (IMR) is among the most serious complications of myocardial infarction which doubles the late mortality; mainly treated by undersizing ring annuloplasty. To find some preoperative echocardiographic indices that predict immediate failure of mitral valve annuloplasty (MVA), we designed the present study with more focusing on some novel parameters. METHOD: Transthoracic echocardiography (TTE) indices of consecutive patients referred with 3+ or 4+ IMR were registered 24 hours before surgery. Thirty days later, a second TTE was performed. According to the results, the patients were categorized as the "successful" group (with 1+ or less mitral regurgitation) and the "unsuccessful" group (with 2+ or higher MR). Preoperative TTE indices were compared among the two groups using suitable statistical tests. RESULTS: Of the total of 126 cases, 68 had successful and 58 had unsuccessful MVA. Statistically significant differences were found between the two groups for left ventricular ejection fraction (LVEF) (P = 0.007), left ventricular end systolic volume (LVESV) (P = 0.044), and basal-interpapillary muscle distance (IPMD) diastolic-to-systolic ratio (DSR) (P = 0.008). Receiver Operating Characteristic analysis demonstrated 37.5%, 3.85 cm(3) , and 1.25, as the best cutoff points for LVEF (P = 0.03, sensitivity: 81%, specificity: 69%), LVESV (P = 0.023, sensitivity: 83%, specificity: 57%), and basal-IPMD DSR (P = 0.001, sensitivity: 100%, specificity: 95%), respectively. CONCLUSION: Among all TTE indices, LVEF, LVESV, and basal-IPMD DSR were helpful to differentiate between the successful and unsuccessful MVA results. We believe the basal-IPMD DSR as a novel index could be targeted in the future studies.

Biatrial myxoma in a young lady.

A healthy 28-year-old woman, presenting with a chronic cough for approximately 6 months, was referred for echocardiography. The images revealed the presence of two masses in each atrium without an inter-atrial septal defect. No additional abnormalities were detected during the clinical examinations. Subsequently, the patient underwent a successful surgical procedure for the removal of the cardiac masses.

A rare case of myxoma mimicking pulmonary thromboembolism: a case report.

Studies have shown that primary cardiac tumors are exceptionally rare and among them myxomas represents approximately half. Although majority of these benign tumors are located in left atrium, they can also emerge in the right cardiac chambers and also on cardiac valves. In rare instances, they may extend into the great vessels. In this case, we present a teenage girl with a past medical history of successfully cured acute lymphoblastic leukemia, who presented with progressive dyspnea and lower limbs edema. Based on history, laboratory, and echocardiographic evidences, she was initially treated for high-risk thromboembolism but after inefficient response, she underwent surgery, with a large right ventricular outflow tract myxoma being diagnosed.

Comparison of Qanadli score with conventional risk stratifiers in non-massive pulmonary emboli.

OBJECTIVE: The management and risk stratification of non-massive pulmonary embolism (PE) remain unclear. However, early assessment of PE severity can aid physicians in establishing better treatment milestones. There has been no direct comparison of mortality rates in patients with non-massive PE, and existing data are sometimes contradictory. Therefore, we examined the relationship between the Qanadli index and conventional risk stratifiers in PE. METHODS: We retrospectively analyzed 200 consecutively selected patients diagnosed with PE. The assessment included computed tomography pulmonary angiography, electrocardiography, echocardiography findings, outcomes, and a comparison with the Simplified Pulmonary Embolism Severity Index (SPESI) score. Descriptive, regression, and receiver operating characteristic analyses were performed. RESULTS: The mean Qanadli score was 13.5 ± 1.15. Pearson correlation analysis revealed significant associations between the total Qanadli score and several variables: right ventricular enlargement, follow-up ejection fraction, and SPESI score. Although the Qanadli score did not significantly predict mortality, the risk of death increased by 58.8% for each 1-unit increase in the SPESI score. CONCLUSIONS: Although the Qanadli index is valuable in assessing PE and guiding treatment strategies, its standalone predictive value for mortality may be insufficient. Therefore, incorporating scoring systems such as the SPESI and echocardiographic findings is recommended for more accurate mortality prediction.

The diagnostic value of N-terminal pro-brain natriuretic peptide in differentiating cardioembolic ischemic stroke.

BACKGROUND: There has been debate regarding whether natriuretic peptides can be used as a marker to distinguish cardioembolic (CE) origin of ischemic stroke from other subtypes. Therefore, the aim of this study was to study the value of N-terminal pro B-type natriuretic peptide (NT-proBNP) in differentiating CE from other subtypes of stroke in patients with acute ischemic stroke. METHODS: All 125 consecutive patients with acute ischemic stroke in a 1-year period were included. Admission blood samples of all patients were analyzed for the serum level of NT-proBNP. Patients were evaluated for etiology of stroke by imaging modalities and classified based on Trial of Org 10172 in Acute Stroke Treatment criteria. Medical history and risk factors for vascular diseases were also obtained. Receiver operating characteristic (ROC) analysis was used for estimating the diagnostic performance of NT-proBNP levels. RESULTS: Patients were a mean of 67.5 ± 12.6 years of age, and 60 (48%) were men. The most frequent subtype of stroke (57 patients) was CE (45.6%). Levels of NT-proBNP at admission were significantly higher in the CE group (P = .001). After omitting confounding variables, NT-proBNP levels and age were independent predictors of CE stroke subtype. ROC analysis revealed that the diagnostic performance of NT-proBNP levels (area under the curve), optimum cutoff point and its sensitivity and specificity were 0.882 ± 0.031pg/mL, 342 pg/mL, 93%, and 75%, respectively. CONCLUSIONS: NT-proBNP has an acceptable diagnostic value in distinguishing CE ischemic stroke from other subtypes. It can be used to differentiate the stroke subtype and facilitate the treatment process in these patients.

Endocarditis caused by Aspergillus fumigatus in a patient 9 months after COVID-19 infection recovery: a case report and review of the literature.

BACKGROUND: Aspergillus spp. are among the fungal pathogens that can cause life-threatening infections in patients with a history of COVID-19. CASE PRESENTATION: We present the case of a 58-year-old Iranian woman with post-COVID-19 Aspergillus fumigatus endocarditis complicated by numerous thromboembolisms. She underwent mitral valve replacement surgery and multiple lower extremity embolectomies and was treated with voriconazole, which led to her final recovery. CONCLUSIONS: Aspergillus endocarditis should be considered in any patient with suspected endocarditis who has a history of COVID-19 infection and does not respond to routine antibiotic and antifungal therapy, as COVID-19 interferes with proper immune function, and lack of underlying cardiac conditions and immunodeficiencies does not preclude the diagnosis. Culture and histopathological evaluation of vegetations and emboli, as well as PCR, can confirm the diagnosis. Early initiation of antifungal therapy and surgical removal of infected valves and emboli can improve prognosis in patients with Aspergillus endocarditis.

Return to Work and Associated Factors After the First Hospitalization for Heart Failure.

OBJECTIVE: Heart failure (HF) is a public health problem worldwide. Employment is vital in terms of personal, social, and economic aspects for patients with chronic diseases. The aim of this study is to investigate returning to work and the associated factors after first hospitalization for HF in working- age patients. METHODS: In this retrospective cohort study, patients with the first hospitalization for HF in 2017-2020 who were employed before hospitalization were included. The demographic, occupational, and disease-related variables were compared in subjects with and without returning to work. Next, the relationship between the variables and the number of days off work was examined in participants who had returned to work. RESULTS: The data of 204 participants were analyzed. About 90% of the participants returned to work after one year. There was a significant relationship between not returning to work and higher age, female sex, higher New York Heart Association (NYHA) class, Ejection fraction (EF) ≤ 40%, and history of chronic kidney disease (CKD). Among the participants who had returned to work, income level, cause of work exit, employer support, and the number of rehabilitation sessions had a significant relationship with the number of days off work. CONCLUSION: The results of this study showed that gender, age, EF level, history of CKD, and NHYA class were the most influential factors in returning to work after first HF hospitalization. Furthermore, income, cause of work exit, employer support, and the number of rehabilitation sessions were the most important factors contributing to the number of days off work.

A concealed history behind the disaster: Extremely rare presentations of metformin toxicity in a patient with body dysmorphic disorder.

Metformin is a widely used anti-hyperglycemic agent with weight loss effect properties but besides its various utilities, despite being very rare, it has its characteristic toxicity and adverse effects when used in large doses and for the long-term or in patients with renal impairment. We presented here a case of a 36-year-old woman who developed several presentations with diverse features during three years comprising neuropathic symptoms, severe lactic acidosis, three episodes of cardiogenic shock, acute kidney injury, megaloblastic anemia, pancytopenia, and hyponatremia and did not receive a definite diagnosis after each presentation until when she inadvertently disclosed her abuse of extremely unusual doses of metformin during these three years with aim of weight reduction obsessively without knowing that her symptoms could pertain to metformin overdose. She was eventually diagnosed with a body dysmorphic disorder which led to unreasonable abuse of metformin pills that consequently caused its toxicity. Thereafter, with cease of metformin use and psychiatric treatment, her symptoms did not recur and she was doing well after one year of her last admission. Based on the review of the literature, this is the first case of metformin toxicity in a patient with body dysmorphic disorder who was affected with extremely rare features of this intoxication, nevertheless, every manifestation of the patient was discussed exhaustively according to the current and available medical literature.

Constrictive pericarditis following inactivated virus COVID-19 vaccine: a case report with review of the literature.

Cardiac adverse effects of the COVID-19 vaccine are very rare, myocarditis and pericarditis are the most common amid them, and constrictive pericarditis (CP) is reported to be restricted to a few cases following mRNA COVID-19 vaccines. We report a case of a 72-year-old male patient who developed symptoms of right-sided heart failure, which started after 8 days of receiving the third dose of inactivated virus COVID-19 vaccine and his diagnostic tests comprising transthoracic echocardiography, chest CT scan, cardiac magnetic resonance were in favor of CP. Ultimately, invasive cardiac catheterization confirmed the diagnosis of CP. Due to the lack of satisfactory response to corticosteroid therapy, pericardiectomy was performed, which gave rise to symptom relief progressively and substantially. Considering the temporal course of the patient's symptoms and exclusion of other possible etiologies based on the patient's medical history and diagnostic evaluation, immunization with the COVID-19 vaccine was recognized as a culprit for developing CP. Despite being a scarce phenomenon, the COVID-19 vaccine could have a tendency to provoke pericardial inflammation in so far as causing CP. Hence, physicians should have a high index of suspicion in these circumstances and accelerate the diagnostic investigation.

Primary and metastatic primitive neuroectodermal tumor of the heart: A systematic review.

OBJECTIVE: Primary and metastatic primitive neuroectodermal tumors of the pericardium are uncommon. Two cases are presented and discussed. METHODS: The cases of a 17- and 38-year-old male patients with neuroectodermal tumors of the pericardium are presented. In addition, a systematic review was performed according to the Preferred Reporting Items and checklist for Systematic reviews and Meta-Analyses (PRISMA). All selected articles' quality assessment was done using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Case Reports. RESULTS: The systematic review yielded 29 patients with primary or metastatic PNET. Two patients underwent cardiac transplantation. It seems that unlike considering total resection in other organs, pericardiectomy in PNET patients with pericardial origin may lead to further invasion of the lesions, and it is not recommended. The average disease-free follow-up was 10 months. The combination of neoadjuvant and adjuvant chemotherapy along with surgery and radiotherapy offered the best disease-free outcomes. CONCLUSION: Neuroectodermal heart tumors are rare, aggressive tumors requiring chemotherapy and radiotherapy in association with tumor resection surgery to have the best disease-free duration.

A rare case of cardiac metastasis from uterine cervical adenocarcinoma.

Metastatic cardiac tumors are rare and are usually from lung, breast, and esophageal cancers. Although uterine cervical cancer is relatively common, its metastasis to the heart is extremely rare. Herein, we report an unusual case of metastatic cervical adenocarcinoma to the heart presenting with a huge right atrial mass and tamponade. The cardiac mass was surgically resected and pathologic study with immunohistochemistry staining confirmed the diagnosis. .
