Coronary intervention for severe stenosis in the ostial right coronary artery with cardiac angiosarcoma: a case report.

ABSTRACT:

Background

Although rare, angiosarcoma is the most common type of cardiac primary malignancy. This disease can cause life-threatening complications and the prognosis remains poor. There is no standard approach to care, and clinical judgement is exercised on a case-by-case basis. Tumour progression causes serious complications, such as heart failure and vascular disruption.

Case summary

A 64-year-old Japanese woman presenting with a right atrial tumour was referred to our department. Tumour biopsy revealed that the patient suffered from angiosarcoma. We performed a lumpectomy to excise the tumour, but due to tissue adhesions in and around the right atrium, the malignancy could not be completely removed. After 3 years of chemotherapy, the patient was admitted to our hospital with increased chest pain. Emergency coronary angiogram revealed severe stenosis of the ostial right coronary artery. Intravascular ultrasound (IVUS) and computed tomography suggested coronary compression due to cardiac angiosarcoma. In this study, we report a unique case of advanced cardiac angiosarcoma, presenting as unstable angina, which was successfully treated with percutaneous coronary intervention using stent implantation.

Discussion

Due to the rarity of cardiac primary angiosarcoma, many symptoms are misdiagnosed until mechanical complications arise, such as coronary compression. The clinical course and various imaging modalities are useful for differentiating angiosarcomas from coronary stenosis.

Coexistence of left main and right coronary artery ostial stenosis: demographic and angiographic features.

Project description:This study was designed to evaluate ostial left main coronary artery (LMCA) stenosis and investigate concomitant stenotic lesions of LMCA and right coronary arteries (RCA) and their demographic and angiographic features. We evaluated 11,283 patients who underwent coronary angiography. Patients were placed into four groups according to having ostial or nonostial LMCA or RCA stenosis. Significant LMCA stenosis was observed in 242 (8.3%) of the patients, and only 68 (28.1%) of them had significant ostial LMCA stenosis. There was a significant correlation between ostial stenosis of LMCA and RCA (p = 0.03). The frequency of female gender was greater in ostial LMCA and ostial RCA stenosis groups compared with the other groups (p = 0.01). Ostial LMCA and RCA stenosis were related significantly. Both female predominance and coexistence of ostial LMCA and RCA stenosis might have suggest a different pathological ground for this disease.

An echocardiographic clue for ostial left main coronary artery stenosis.

Project description:Calcified nodules in human coronary arteries are usually focally distributed. Non-invasive imaging of coronary arteries by bedside emergency transthoracic echocardiography in adults is possible and may become a useful adjunct to other methods of coronary artery examination. Coronary artery stenosis can be identified as localized color aliasing and accelerated flow velocities. Complete visualization of individual ostial coronary segments might ease the demonstration of coronary stenosis by bedside transthoracic echocardiography. The left main coronary artery stenosis requires prompt emergency evaluation and treatment because emergency conditions have higher mortality rates. The authors wish to emphasize the usefulness of emergency bedside echo-Doppler for a prompt diagnosis and treatment of this life-threatening condition.

Absent right coronary artery: A case of single coronary artery or congenital ostial atresia?

Project description:Atresia of the right coronary artery ostium is a rare anatomic variant of the coronary circulation. It is often difficult to differentiate from single coronary artery. Its presence unassociated with any other anomaly has never been described in an adult individual. We report this unusual anomaly and discuss its anatomical and pathophysiological significance and possible ways to differentiate from single coronary artery.

ST segment elevation caused by ostial right coronary artery obstruction in infective endocarditis: a case report.

Project description:BACKGROUND:Acute coronary syndrome (ACS) is a rare, but serious complication of infective endocarditis, and diagnosis can be challenging given clinical overlap with other syndromes. A rare cause of ACS in infective endocarditis is mechanical obstruction of the coronary artery. We present the case of a patient with infective endocarditis who developed ST segment myocardial infarction due to occlusion of the right coronary artery ostium by a vegetation. CASE PRESENTATION:A 53-year-old female with no prior history of coronary artery disease was transferred to our tertiary care facility for evaluation and treatment of suspected myopericarditis. After transfer she developed inferior ST segment elevations on ECG along with fever and positive blood cultures for methicillin susceptible Staphylococcus aureus (MSSA). A transesophageal echocardiogram revealed a vegetation on the aortic valve that intermittently prolapsed into the right coronary ostium. She decompensated from a hemorrhagic brain infarct and subsequently transferred to the intensive care unit. She underwent surgical aortic valve debridement without prior cardiac catheterization given the danger of septic coronary embolization. After a prolonged hospital course with multiple complications, she was able to discharge home, with no neurologic deficits on follow-up. CONCLUSIONS:ACS presents a diagnostic and therapeutic challenge in the setting of infective endocarditis. Careful attention to the history, physical exam and testing can help differentiate infective endocarditis from other conditions sharing similar symptoms. Traditional atherosclerotic ACS management may cause great harm when treating patients with infective endocarditis. The presence of a multidisciplinary endocarditis team is ideal to provide the best clinical outcomes for this population.

Giant right coronary artery aneurysms presenting as a cardiac mass: Case report.

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.

Successful recognition and percutaneous coronary intervention of delayed severe multiple coronary artery dissection caused by cardiac surgery: a case report.

Project description:BackgroundMultiple coronary artery dissection is rare after cardiac surgery. It is difficult to recognize and is easily misdiagnosed as low output syndrome as a result of cardiopulmonary bypass (CPB).Case presentationA 43-year-old woman who had undergone cardiac surgery presented with unstable hemodynamics, and progressively increasing lactate, B-type natriuretic peptide, and cardiac enzyme levels, along with electrocardiogram (ECG) changes. Angiography indicated the presence of severe multiple coronary artery dissection, and 3 stents were implanted, which improved the patient's hemodynamic status and cardiac function.ConclusionsIn the present report, we describe our experience with identifying and treating delayed severe multiple coronary artery dissection caused by cardiac surgery. Timely angiography is vital in patients suspected with coronary artery dissection, and percutaneous coronary intervention (PCI) should be considered as a treatment strategy for cases with severe multiple coronary artery dissection and unstable hemodynamics after cardiac surgery.

Treatment of Ostial Right Coronary Artery Narrowings: Outcomes From the Multicenter Prospective e-ULTIMASTER Registry.

Project description:BackgroundTreatment of right coronary artery (RCA) aorto-ostial (AO) lesions with bare-metal stents and first-generation drug-eluting stents (DES) was associated with worse outcomes. This study aimed to assess the effect of RCA-AO stenting with current-generation DES on the clinical outcome.MethodsThe large all-comer, multicontinental e-ULTIMASTER registry included 37,198 patients of whom 4775 underwent ostial and proximal RCA percutaneous coronary intervention (PCI) using the Ultimaster stent (Terumo). The primary clinical end point was 1-year target lesion failure (TLF), a composite of cardiac death; target vessel-related myocardial infarction; or clinically indicated target lesion revascularization.ResultsWe compared 591 (12.4%) patients who underwent RCA-AO PCI with 4184 (87.6%) patients who underwent proximal RCA PCI. The RCA-AO group included more men and recorded significantly more comorbidities and more complex coronary anatomy. After propensity matching, the primary end point TLF occurred in 4.49% of the RCA-AO group compared with 3.00% of the proximal RCA group (P = .06). Target vessel revascularization (3.29% vs 1.90%; P = .03) and stent thrombosis (1.23% vs 0.42%, P = .01) were significantly higher among patients with RCA-AO lesions than those among patients with proximal RCA lesions. All-cause mortality was similar between the groups (2.97% vs 2.26%; P = .30).ConclusionsThe treatment of RCA-AO with DES is feasible, with similar rates of TLF but with an increased risk of target vessel revascularization and stent thrombosis.

Percutaneous coronary intervention to left anterior descending artery/right coronary artery bifurcation: this is not a typo! A case report.

Project description:BackgroundAnomalous origin of the right coronary artery (RCA) is a rare congenital anomaly. A single coronary artery arising from the left sinus of Valsalva, with the RCA originating from the left anterior descending artery (LAD), is extremely rare. We report the case of an anomalous origin of the RCA from the mid LAD with a significant bifurcation lesion, in the setting of an acute coronary syndrome, endangering both the RCA and LAD territories.Case summaryAn 85-year-old female presented with a non-ST elevation acute coronary syndrome. Transradial coronary angiography revealed an anomalous origin of the RCA arising from the mid LAD beyond a large first septal perforator. There was significant stenosis involving anomalous RCA/LAD bifurcation classified as Medina 1, 1, 1. Following discussion at heart team meeting, she underwent successful percutaneous coronary intervention. The LAD/RCA bifurcation was treated using a two-stent culotte technique without any complications. Computed tomography coronary angiogram was performed which confirmed a benign course of the anomalous RCA anterior to aorta and pulmonary artery.DiscussionThis anomaly poses a significant challenge in revascularization due to the large area of myocardium subtended by the LAD and RCA and usually an acute angle of bifurcation. Moreover, CTCA can be useful to ascertain the course of anomalous RCA.

Setting things “right”: right internal mammary artery on anomalous right coronary artery - a case report

Project description:Anomalous aortic origin of a coronary artery (AAOCA) is a rare pathology that may cause episodic ischemia owing to possible vessel compression during systolic expansion of the aortic root. This anomaly can lead to myocardial infarction, malignant arrhythmias and sudden cardiac death (SCD). Several surgical techniques have been described; however, there are no defined guidelines regarding the treatment of AAOCA. We report the case of a 47-year-old woman with ectopic origin of the right coronary artery (RCA) from the left sinus of Valsalva, with an interarterial course of the proximal segment of the artery, running between the aorta and the pulmonary trunk. Revascularization was accomplished by harvesting the right internal mammary artery (RIMA) and anastomosing it to the anomalous RCA, given the small portion of the RCA following an intramural course and our familiarity with the procedure. The RCA was ligated proximal to the anastomosis to avoid the string sign phenomenon. This procedure is safe and fast and can be considered an alternative to coronary reconstruction.
