Project description:BackgroundTakotsubo cardiomyopathy (TTC) is a non-ischaemic cardiomyopathy, characterized by transient wall motion abnormalities of the left ventricle. Although biventricular involvements are common with a poor prognosis, isolated right ventricular (RV) involvement of TTC is a rare, and its diagnosis remains challenging.Case presentationWe encountered a case of isolated RV-TTC presenting as acute RV failure, with progression to cardiogenic shock requiring intensive treatment. Conflicting echocardiographic findings of RV asynergy with RV enlargement despite normal left ventricular wall motion and mild tricuspid regurgitation led to the correct diagnosis. Finally, the patient showed complete recovery with normalization of cardiac structure and function.ConclusionsThis case underscores the clinical significance of considering isolated RV-TTC as a new distinct variant form of TTC in terms of presentation, diagnostic findings, differential diagnosis, treatment strategy, and prognosis.

Project description:BackgroundMyxoma is an uncommon disease and its symptoms vary greatly depending on size, location and mobility. Right-sided myxoma, especially right ventricular myxoma, is much rarer, and the symptoms are alien and uncharacteristic. The lack of understandings poses challenges to prompt diagnosis and timely treatment.Case presentationA 44-year-old female patient was diagnosed with giant right ventricular tumor. Right heart failure and systemic congestion caused by right ventricular outflow tract obstruction were observed on this case. Surgery was performed to excise the mass which was measured at 9.5 * 5.0 cm and confirmed as myxoma pathologically.ConclusionsRight-side myxoma is easy to be unnoticed due to its low incident rate and atypical symptoms. Delay in surgical intervention might cause unrecoverable complications. More comprehensive understanding of the symptoms is expected to help improving the diagnose and treat of right-sided myxoma.

Project description:IntroductionCoronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of the normal adjacent artery segments or the diameter of the patient's largest coronary artery by 1.5 times. The incidence of giant CAA is difficult to be determined, since only few reports have been described in the literature.Methods and resultsA 65-year-old man was referred to our hospital because of a "mass" in the right heart detected on echocardiography at a regular medical health examination, while he experienced no any symptoms. Coronary angiography showed the severe stenosis of the left anterior descending artery (LAD) and the left circumflex artery (LCX) and the diffusely ectatic change of the right coronary artery (RCA), but no mass was found in any of these arteries. Coronary computed tomography angiography (CTA) confirmed that the "mass" was the giant aneurysms of RCA with thrombus. He received coronary artery bypass graft (CABG) with thrombectomy. The histopathology showed the deposits of lipid and hyalin in the tunica intima, the focal calcifications, the very thin tunica media, and the disappearance of the part of the tunica media in the RCA.ConclusionsCoronary artery aneurysm which may contain thrombus can complicate a diagnostic coronary angiography due to the risk of distal embolization and may lead to myocardial infarction. This case report demonstrates 2 RCA aneurysms with a thrombus presenting as a giant "mass" which was successfully treated by CABG with thrombectomy.

Project description:Histiocytic sarcoma is a rare hematologic malignancy, with very few cases of primary histiocytic sarcoma of the breast described in English scientific literature. Herein, we describe a case of primary histiocytic sarcoma of the breast in a 75-year-old woman, with no clinical history of malignant tumors, who presented with a palpable solitary breast mass. Microscopically, the resected breast mass showed large pleomorphic cells, some multinucleated giant cells, and admixed inflammatory components. The pleomorphic tumor cells further showed a diffuse, noncohesive growth pattern, an abundant eosinophilic cytoplasm, and strong and diffuse immunoreactivity for cluster of differentiation (CD) 68 and CD163. Furthermore, a whole-body positron-emission tomography/computed tomography using deoxy-2-[18F]fluoro-D-glucose performed after surgery showed no other masses or lesions. After surgical excision, the patient was followed up, and no evidence of tumor recurrence or metastasis was noted.

Project description:Vascular malformations are developmental anomalies occurring due to defective vasculogenesis. Depending on the number of vessels involved, they are subgrouped into simple or combined types. Combined vascular malformations are a rare clinical entity with two or more vascular malformations (capillary, venous, arteriovenous, lymphatic) present in one lesion. Due to the complexity of these lesions, clinicians should employ an interdisciplinary approach with multi-staged treatment for the proper management. Here, we report a case of a lady with a combined vascular malformation in the right side of the neck who presented to our department with a complaint of progressively increasing swelling for three months. A multidisciplinary team of vascular surgeons, interventional radiologists and physiotherapists were involved in its treatment. Initially, Doppler ultrasonography was performed, which revealed a vascular lesion with arterial and venous components and a flow void region suggestive of lymphatic malformation, further confirmed by magnetic resonance imaging (MRI). A multistage treatment modality was employed where intralesional steroid was initially administered in the lesion area to shrink the vessel's size. Next, venous malformation targeted sclerotherapy was performed preoperatively, followed by intraoperative ligation of the feeding vessel and excision of remaining malformation. Postoperatively the patient had no wound site complication and was discharged on the fourth postoperative day with advice to follow rehabilitative neck exercises. One month follow-up revealed complete resolution of the malformation. Thus, in the case of combined vascular malformation, multistage treatment modalities with a multidisciplinary team should be employed for proper treatment.

Project description:We report a 65-year-old male patient who presented with right heart failure and a large mobile right atrial and ventricular mass on echocardiography. His computed tomography demonstrated bilateral supraclavicular/mediastinal lymphadenopathy, right atrial and ventricular mass with right pulmonary artery segmental embolism, and multiple liver hypodense lesions. His tumor markers were negative. However, fine-needle aspiration cytology of supraclavicular lymph node revealed metastatic carcinoma suggestive of squamous cell carcinoma. He was suspected to have carcinoma of unknown primary origin. This case illustrates a rare presentation of carcinoma of unknown primary origin with disseminated tumor thrombosis primarily manifesting in heart and other sites.

Project description:Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma, is a neoplasm that occurs most often in the extremities, trunk, and retroperitoneum. Rarely, UPS can occur in the cardiac chambers and great vessels. The diagnosis of UPS is difficult to establish with noninvasive imaging techniques, and these tumors may be mistaken for benign neoplasms preoperatively. Surgical excision is the standard therapy, although the extent and location of the tumor may limit the ability to perform a complete resection. Adjuvant chemotherapy and/or radiation are often used for incomplete resections. We report the case of a 57-year-old woman with a large right ventricular UPS who presented with signs of right-sided heart failure. Preoperative imaging was suggestive of a myxoma; however, histopathologic evaluation of the specimen confirmed a diagnosis of UPS. Microscopic margins of the specimen were positive, and adjuvant chemotherapy was given. We discuss diagnostic and treatment considerations for this unusual cardiac tumor. <Learning objective: The diagnosis and treatment of primary cardiac tumors are challenging. Noninvasive imaging often lacks the sensitivity and specificity to differentiate between benign and malignant neoplasms. In addition, the extent and location of tumor involvement may limit the ability to perform a complete resection. The diagnosis and treatment of right ventricular undifferentiated pleomorphic sarcoma are discussed.>.

Project description:BackgroundIsolated right ventricular myocardial infarction (RVMI) due to a recessive right coronary artery (RCA) occlusion is a rare presentation. It is typically caused by right ventricle (RV) branch occlusion complicating percutaneous coronary intervention. We report a case of an isolated RVMI due to flush RCA occlusion presenting via our primary percutaneous coronary intervention ST-elevation myocardial infarction pathway.Case summaryA 61-year-old female smoker with a history of hypercholesterolaemia presented via the primary percutaneous coronary intervention pathway with sudden onset of shortness of breath, dizziness, and chest pain while walking. Transradial coronary angiography revealed a normal left main coronary artery, large left anterior descending artery that wrapped around the apex and dominant left circumflex artery with the non-obstructive disease. The RCA was not selectively entered despite multiple attempts. The left ventriculogram showed normal left ventricle (LV) systolic function. She was in cardiogenic shock with a persistent ectopic atrial rhythm with retrograde p-waves and stabilized with intravenous dobutamine thus avoiding the need for a transcutaneous venous pacing system. A computed tomography pulmonary angiogram demonstrated no evidence of pulmonary embolism while an urgent cardiac gated computed tomography revealed a recessive RCA with ostial occlusive lesion. A cardiac magnetic resonance imaging confirmed RV free wall infarction. She was managed conservatively and discharged to her local district general hospital after 5th day of hospitalization at the tertiary centre.DiscussionThis case describes a relatively rare myocardial infarction presentation that can present with many disease mimics which can require as in this case, a multi-modality imaging approach to establish the diagnosis.

Project description:Hypertrophic cardiomyopathy (HCM) can involve the right ventricle (RV), although RV hypertrophy usually exists with left ventricular (LV) hypertrophy and the severity of hypertrophy is milder in the RV than in the LV. We report a case of isolated extreme RV hypertrophy with a maximum RV wall thickness of 40 mm. A 72-year-old man presented with an abnormal electrocardiogram and isolated hypertrophy of the RV apex was found on echocardiography. A diagnosis of HCM was made based on myocardial features on multiple imaging modalities such as the similar myocardial characteristics to LV hypertrophy and systolic thickening. The isolated hypertrophy of the RV apex exhibited partial calcification, which was surrounded by hypoperfused areas of the myocardium on multidetector computed tomography. <Learning objective: Patients with hypertrophic cardiomyopathy (HCM) are characterized by left ventricular hypertrophy unexplained by secondary causes, although right ventricular (RV) involvement can develop. We report a case of isolated extreme RV HCM with a maximum wall thickness of 40 mm accompanied by intramyocardial calcification, highlighting the importance of acknowledging the diverse phenotypes in HCM.>.

Project description:Large intracavitary masses such as those occupying most of a cardiac chamber and obstructing blood flow are not routinely encountered in clinical practice. The differential diagnosis includes neoplastic as well as nonneoplastic causes. Primary cardiac tumors by themselves are uncommon. We hereby report a rare case of a middle-aged female presenting with New York Heart Association Class III symptoms, whose transthoracic echocardiogram revealed a huge mass in right-sided chambers with a novel double ball valve type movement. She successfully underwent urgent surgical resection of the mass with histopathological confirmation of diagnosis.
