Double Embolism: A Very Rare Presentation of Concurrent Pulmonary Embolism and Embolic Stroke without Arterivenous Shunt.

Embolic material forms in many parts of the body and can affect anywhere in the body. Pulmonary embolism and embolic stroke are the most common presentations of embolic disorders in the body. Embolic events have different causes, and the heart is one of the most important places where emboli originate. One of the uncommon causes of embolic events is non-bacterial thrombotic endocarditis (NBTE), which can occur in patients with advanced cancer. NBTE can lead to embolism. Embolisation may occur in some organs including the central nervous system, kidneys, spleen, limb extremities, and coronary arteries. The authors aim to describe a rare case with concurrent pulmonary embolism (PE) and embolic stroke caused by non-bacterial thrombotic endocarditis (NBTE) in a woman with breast cancer.

A case of cardiac angiosarcoma and pulmonary tuberculosis; diagnostic challenges and review of literature.

BACKGROUND: Patient symptoms and primary investigational methods may be misleading at some points in patient management and can consume a lot of time. Sarcomas are rare malignancies and contribute 1% of all cancers of adult. CASE PRESENTATION: A rare case of primary cardiac angiosarcoma is presented, who was first treated because of lung tuberculosis and then with only slight improvement in symptoms, further investigations were done showing right ventricular enlargement and pericardial effusion. Eventually, after ruling out pulmonary embolism and constrictive pericarditis, investigations lead to the diagnosis of primary cardiac angiosarcoma. The patient went under surgery to remove the tumor but he still had residual mass left, leading to chemotherapy and then radiotherapy. Although the tumor has a poor prognosis, our patient has managed to survive a year by now and is doing good for 6 months after radiotherapy. CONCLUSION: The case describes the importance of having in mind different differential diagnosis in managing patients and the role of multi-modality imaging in guiding diagnosis and treatment.

Yazd Province of Iran ICD Registry for the Years 2014-2016.

OBJECTIVE: This study aimed to investigate the trends in the care of patients undergoing implantable cardioverter-defibrillator (ICD) implantation in our region and to analyze whether the quality of care is the same as the other centers or not? METHODS: Adult patients with an indication for ICD implants were enrolled in our registry and followed over a 19-43-month period. RESULTS: The ICD implantation rate was 100/million per year. The mean age of patients treated with ICD was 62.36 (±12.93) years old and the majority of patients were men (77.6%). Most patients had ischemic heart failure (65.2%). Nearly half of the patients had NYHA class III (53.8%) and the mean of ejection fraction was 26.7 (±9.8%). ICDs were frequently implanted for primary prevention (71.9%). Single chamber ICDs (ICD-VR) were chosen in 25.2%, dual-chamber ICDs in 37.1% (ICD-DR) and biventricular ICDs (CRT-D) in 37.6%, respectively. Complications related to ICD implantation occurred in about 7.49% of all procedures. During follow-up period death occurred in 14.8% of our patients. Also, 13.3% of patients received ICD shock which was appropriate in 71% of patients. CONCLUSIONS: In comparison between our registry and NCDR registry, baseline patient characteristics and ICD type were almost the same, but the complication rate was higher. There is still a need to perform a large multicenter registry in our community to improve our knowledge in this Era.

Methadone induced torsades de pointes and ventricular fibrillation: A case review.

BACKGROUND: Methadone is a synthetic opioid, which has been successfully used in treating heroin addiction and chronic pain syndrome in palliative care for more than 30 years. This drug is a potent blocker of the delayed rectifier potassium ion channel, which may result in corrected QT (QTc) interval prolongation and increased risk of torsades de pointes (TdP) in susceptible individuals. CASE REPORT: We describe here a case of methadone-induced TdP that deteriorated into ventricular fibrillation, which was resolved after treatment with IV magnesium, potassium, and Lidocaine. Our purpose in this case review was to highlight the risk of cardiac arrhythmias, in particular QTc interval prolongation leading to TdP in a heroin-dependent patient receiving methadone substitution therapy, and then to present a perspective on treatment and prevention strategies of methadone induced prolonged QTc. CONCLUSION: Methadone-induced TdP is a potentially fatal complication of methadone therapy. As the popularity of methadone use grows, clinicians will encounter more cases of methadone induced TdP, especially in our region, Iran. Hence, a thorough patient history and electrocardiogram monitoring are essential for patients treated with this agent, and alterations in treatment options may be necessary.
