Background: Infectious endocarditis (IE) is an infectious disease caused by direct invasion of the heart valve, endocardium, or adjacent large artery endocardium by pathogenic microorganisms. Despite its relatively low incidence, it has a poor prognosis and a high mortality. Intracranial infectious aneurysms (IIA) and ruptured sinus of Valsalva aneurysm (RSVA) are rare complications of IE., Case Presentation: We report a young male patient with symptoms of respiratory tract infection, heart murmurs and other symptoms and signs. The patient also had kidney function impairment and poor response to symptomatic therapy. Blood culture was negative, but echocardiography was positive, which met the diagnostic criteria for infective endocarditis. Moreover, an echocardiography showed a ruptured sinus of Valsalva aneurysm with a ventricular septal defect. Finally, secondary rupture of an IIA with multiple organ damage led to a poor clinical outcome., Conclusion: Therefore, in the clinical setting, for young patients with unexplained fever, chest pain, or palpitations, we need to be highly vigilant, considering the possibility of infective endocarditis and promptly performing blood culture, echocardiography, cerebrovascular imaging and so on, in order to facilitate early proper diagnosis and treatment., (© 2024.

Introduction: Sinus of Valsalva aneurysm (SOVA), a rare cardiac malformation, is usually congenital and rarely acquired and most commonly occurring in the right coronary sinus. The clinical presentation of patients with SOVA varies. It is usually asymptomatic when it has not ruptured, and when it compresses neighboring structures or ruptures, it can lead to heart failure or shock, at which point urgent surgical intervention is usually required. Rupture of the sinus of Valsalva aneurysm (RSOVA) during pregnancy is really hard to come by, especially if the clinical presentations resemble that of an acute myocardial infarction. This report describes a pregnant woman with severe chest pain and hypotension with aVR and V1 ST-segment elevation due to RSOVA., Patient Concerns: Effects of RSOVA on the fetus, disease survival, and prognosis., Diagnosis: RSOVA., Interventions: Open SOVA repair., Outcomes: The patient's blood pressure returned to normal range and clinical symptoms disappeared after the surgery. After 3 months of follow-up, the patient was hemodynamically stable without chest discomfort, and an echocardiogram showed a normal aortic sinus., Conclusion: Progressive aneurysm dilatation or rupture has a poor prognosis. A thorough history and physical examination are fundamental, with echocardiography being the initial diagnostic tool of choice, and other ancillary tests (e.g., computed tomography) being used to complement and confirm the diagnosis. Surgery remains the current treatment of choice for patients with RSOVA, while the continuation of pregnancy in pregnant patients with RSOVA remains a case-by-case measure., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Anomalous aortic origin of a coronary artery from the inappropriate sinus of Valsalva (AAOCA) is a rare congenital heart lesion. It is uncommon for patients with AAOCA to present with severe symptoms at a very young age., Case Presentation: We describe a very rare but critical presentation in a young infant with AAOCA that requires surgical repair and pacemaker placement. A three-month-old infant was referred because of syncope. Cardiac arrest occurred shortly after admission. The electrocardiogram indicated a complete atrioventricular block and a transvenous temporary pacemaker was implanted. A further coronary computed tomographic angiography (CTA) showed the anomalous origin of the right coronary artery from the left sinus of Valsalva. Coronary artery unroofing was performed due to an interarterial course with the intramural component, and a permanent epicardial pacemaker was implanted. The postoperative recovery was uneventful, and this patient was thriving and asymptomatic at the nine-month follow-up. However, the electrocardiogram still indicated a complete pacing rhythm., Conclusions: By timely diagnosis and treatment, this patient is successfully rescued. Although rare, AAOCA may be fatal even in infants., (© 2024. The Author(s).)

Sinus of Valsalva aneurysm (SoVA) is a rare disease with less than 1% prevalence in the population. Most cases are asymptomatic, however, significant clinical manifestations are possible due to fistula formation and sudden rupture resulting in cardiac shunt. Eventually it may develop into progressive heart failure with high morbidity. We report the case of a 33 year old female patient who presented with shortness of breath, ascites, and recurring hospitalisation. The cardiac examination revealed sinus tachycardia along with loud and continuous murmurs on the left parasternal border. Several standard diagnostic procedures could not be performed due to malignant arrhythmia in supine position. Echocardiography examination revealed SoV rupture with a gerbode defect, which was the underlying cause of severe retractable heart failure.

A rare case of an anomalous location of the orifice of the coronary artery was found in a 99-year-old male cadaver undergoing routine dissection. The presence of the right coronary artery (RCA), left coronary artery (LCA), and conus artery (conus branch) originating from the right Valsalva sinus are the characteristic findings of this case. Then, the LCA passed through the aorta and the pulmonary artery. The LCA and RCA branches were normal. These findings are useful for future surgical procedures, including cardiac catheterization.

Background: Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly which can be congenital or acquired. Patients with SVA are commonly asymptomatic when the occupying effect of SVA is insignificant, while ruptured SVA usually causes severe symptoms including heart failure and myocardial ischemia., Case Presentation: We present an unusual case of a 64-year-old female manifesting with exertional dyspnea as well as angina pectoris for three months. Echocardiography and cardiac computed tomographic angiography confirmed unruptured left-coronary and non-coronary SVAs. The left anterior descending artery and left circumflex artery were stretched and compressed by the SVA which causing myocardial ischemia. The patient finally received aortic root replacement (Bentall procedure) and got symptom relieved., Conclusions: Giant unruptured SVA originating from left coronary sinus is extremely rare. Our case highlights that giant SVA should be considered in cases with angina pectoris. Echocardiography and coronary computed tomographic angiography are useful and important for diagnosis. Surgery is highly recommended in patients with SVA., (© 2024. The Author(s).)

Background: This study aimed to investigate the predictive value of parameters of every precordial lead and their combinations in differentiating between idiopathic ventricular arrhythmias (IVAs) from the right ventricular outflow tract and aortic sinus of Valsalva (ASV)., Methods and Results: Between March 1, 2018, and December 1, 2021, consecutive patients receiving successful ablation of right ventricular outflow tract or ASV IVAs were enrolled. The amplitude and duration of the R wave and S wave were measured in every precordial lead during IVAs. These parameters were either summed, subtracted, multiplied, or divided to create different indexes. The index with the highest area under the curve to predict ASV IVAs was developed, compared with established indexes, and validated in an independent prospective multicenter cohort. A total of 150 patients (60 men; mean age, 45.3±16.4 years) were included in the derivation cohort. The RV1+RV3 index (summed R-wave amplitude in leads V1 and V3) had the highest area under the curve (0.942) among the established indexes. An RV1+RV3 index >1.3 mV could predict ASV IVAs with a sensitivity of 95% and a specificity of 83%. Its predictive performance was maintained in the validation cohort (N=109). In patients with V3 R/S transition, an RV1+RV3 index >1.3 mV could predict ASV IVAs, with an area under the curve of 0.892, 93% sensitivity, and 75% specificity., Conclusions: The RV1+RV3 index is a simple and novel criterion that accurately differentiates between right ventricular outflow tract and ASV IVAs. Its performance outperformed established indexes, making it a valuable tool in clinical practice.

A young female patient presented with complaints of breathlessness and palpitations since 2 years. On clinical examination, there was a loud continuous murmur at the right sternal border.Transthoracic echocardiography and colour Doppler showed a tunnel-like structure originating from the aneurysmal right coronary sinus and opening into the right atrium with left to right shunt. Coronary angiography revealed a large tunnel beginning in right coronary sinus and terminating in the right atrium and right coronary artery (RCA) was seen originating from the tunnel. Cardiac catheterisation revealed normal pulmonary artery pressure. CT and 3D-reconstructed images delineated the extracardiac course of the tunnel.Various treatment modalities including percutaneous transcatheter approach and surgical treatment were taken into consideration, but because of the close proximity of RCA from the tunnel opening, surgical closure was preferred., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Ruptured sinus of Valsalva aneurysm (RSOVA) is a rare cardiac condition associated with high morbidity and mortality rates. We herein report a 35-year-old man with a history of ventricular septal defect (VSD). He had a history of interrupted hospital visits and presented to the emergency department with dyspnea, palpitations, and dizziness for a few days. Auscultation detected a continuous murmur. Transthoracic echocardiography followed by transesophageal echocardiography demonstrated RSOVA in the right ventricle with an aorto-right ventricular fistula. The fistula was resected, and the aneurysm was surgically repaired. The patient made a good recovery.

Background: Sinus of Valsalva aneurysm (SVA) is an extremely rare condition, and its rupture causes acute symptoms such as chest pain and dyspnea. Ruptured SVA is frequently associated with other congenital defects., Case Presentation: A 37-year-old male presented with SVA originating from the left coronary sinus that ruptured into the interventricular septum. SVA was diagnosed by echocardiography, cardiac computed tomography and magnetic resonance imaging, and confirmed during the operation., Conclusions: SVA is a rare cardiac abnormality which can lead to severe clinical symptoms upon rupture. Immediate surgery is necessary to repair the ruptured SVA., (© 2024. The Author(s).)

A 69-year-old man with unstable angina underwent coronary angiography showing no lesion in the left coronary artery and critical stenosis in the proximal right coronary artery (RCA) arising from the left sinus of Valsalva.

Background: Anomalous coronary arteries are rare congenital variations with cases ranging from asymptomatic to life-threatening. Given the wide variability of coronary anomalies, it is challenging to predict their clinical consequences. Here, we present the 'malignant' variant - interarterial course of the left coronary artery between the aorta and pulmonary trunk - given the highest risk of sudden cardiac death among the various coronary anomalies., Case Presentation: Our case presents a 22-year-old male presenting to the emergency department after a syncopal episode that occurred while the patient was driving a motor vehicle. Initial Computed Tomography (CT) of the chest performed as part of the trauma work-up revealed a rare case of an anomalous origin of the left main coronary artery (LMCA) originating from a common ostium with the right coronary artery (RCA). The LMCA was found to have a malignant course, as it was positioned between the aorta and pulmonary artery. Given the high risk of sudden cardiac arrest with this congenital variant, the patient underwent coronary artery bypass grafting., Conclusion: Anomalous coronary arteries remain the second leading cause of sudden cardiac death in young adult patients. The risk of sudden cardiac death depends on the congenital variant of the anomalous coronary artery as well as the course these vessels take. This case highlights a rare congenital variant featuring both the LMCA and RCA originating from a common ostium, with the LMCA having a malignant course, a variant with the highest risk of sudden cardiac death., (© 2023.

Left sinus of Valsalva aneurysms are extremely rare. Concomitant aortic valve regurgitation is a comorbidity in this pathology. This case report summarizes successful surgical treatment with aortic root replacement with a modified Bentall procedure in a 49-year-old female patient who had an unruptured huge left sinus of Valsalva aneurysm with severe aortic valve regurgitation. The intraoperative assessment showed severe adhesion between the left main trunk of the coronary artery and the left sinus of Valsalva aneurysm, and meticulous adhesion detachment was required., (© 2023 The Author(s).

A man in his 40s presented with haematemesis and melaena and was found to have a massive variceal bleed. Endoscopic procedures were ineffective at controlling the bleed; thus, an emergent transjugular intrahepatic portosystemic shunt (TIPS) procedure was performed. There were no noted complications from the procedure and the patient was eventually discharged home. A month later, a murmur was auscultated on routine physical examination. This prompted an outpatient transthoracic echocardiogram which revealed a TIPS stent in the inferior vena cava (IVC) extending into the right atrium along with a ruptured sinus of Valsalva with left to right shunt.The patient declined surgical intervention. He is currently being followed in the outpatient setting with serial echocardiograms and medical management., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Background: Aim of the study was to collect and describe a case series of consecutive master athletes in whom an anomalous origin of left circumflex artery (LCx) from the right sinus of Valsalva (ALCx) was detected at a clinically indicated coronary computed tomography angiography CCTA) to establish a focused clinical management and counseling about sport activity in those subjects., Methods: We analyzed a prospective registry of subjects referred to a clinically indicated CCTA. Information about the clinical status was obtained by previous clinical records and clinical evaluation at time of image acquisition; follow-up allowed to record symptoms, outcomes and downstream testing., Results: The study population consisted in 14 subjects, of which one competitive athlete and 13 recreational master athletes. Mean age was of 67.2 ± 10.6 years (71% of male); follow-up lasted 6.4 ± 2.6 years. The major high-risk anatomy features (inter-arterial course, intramural segment, high take-off and slit-like ostium) were absent. None had abnormal ostial morphology and all had full retroaortic course; three subjects (21%) presented an acute take-off angle. Coronary artery disease (CAD) was present in 10 patients (71%). Major outcomes (cardiac hospitalization, death for all causes) recorded were not related to the anomalous LCx. Symptoms were most related to atherosclerotic CAD in different vessels whereas two subjects without CAD exhibited cardiac symptoms, without hospitalization., Conclusions: Our study suggests that the diagnosis of ALCx, being usually associated to low-risk anatomical characteristics, could be considered a benign finding, with scarce or no implications for physically active individuals neither for recreational athletes., (© 2023 The Authors.

Few case reports have mentioned the aortic sinus aneurysm invading ventricular septum and dissection caused by Behcet's disease. Here, we reported a 36-year-old male patient with an aortic sinus aneurysm invading the ventricular septum and dissection caused by Behcet's disease, who manifested as recurrent chest tightness and shortness of breath. Cardiac ultrasound showed the rupture of the right aortic sinus and the formation of ventricular septal dissection. Ascending aortic valve prosthesis replacement, mitral valvuloplasty with ring implantation and tricuspid valvuloplasty were performed. Postoperatively, he was treated with hormones, hydroxychloroquine sulfate, mycophenolate mofetil tablets, thalidomide and warfarin, and his symptoms were relieved. This is a rare case easily being misdiagnosed and missed, early diagnosis and in-time treatment are crucial to avoid surgical complications. The diagnostic and therapeutic approaches of this patient were reported and related literature was reviewed in this case report., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Background: The electrophysiological characteristics of idiopathic ventricular arrhythmias (VAs) from the noncoronary sinus (NCS) have not been fully described., Objectives: This study sought to investigate electrophysiological characteristics and catheter ablation in patients with idiopathic NCS-VA., Methods: This study comprised 11 patients undergoing radiofrequency (RF) catheter ablation for idiopathic NCS-VA. Angiography was performed to confirm the origin in the aortic sinus before RF ablation., Results: Clinical arrhythmias presented left bundle block/inferior axis morphology in all patients. QRS morphology of R' and R/s' pattern was dominantly found in lead III. Mapping in the right ventricle demonstrated the earliest ventricular activation (EVA) site at the His Bundle region, whereas mapping in the NCS demonstrated that the EVA preceded the activation at the His Bundle region by 12.1 ± 7.9 milliseconds. All VAs were successfully ablated in <2.5 seconds within the NCS with 1 RF application. The successful ablation site was at the nadir of NCS in 10 patients, and near the junction of NCS and the right coronary sinus in the remaining one. A discrete potential can be observed at the EVA site within the NCS in 10 patients (91%); however, an excellent pace mapping at the EVA site was obtained in only 2 patients. Junctional beats did not occur during RF application in all 11 patients. There were no complications or clinical recurrence during a mean follow-up of 26.0 ± 9.8 months., Conclusions: NCS-VA presents a peculiar electrocardiogram. A discrete potential can be mapped within the NCS during VA and sinus rhythm, and can be used in guiding ablation., Competing Interests: Funding Support and Author Disclosures The study was partially supported by the Science and Technology Program of Guangdong Province, China (No. 2019B020230004), National Key Research.

Trisomy 13 is a rare chromosomal disorder in which all or a percentage (mosaicism) of cells contain an extra 13th chromosome. Sinus of Valsalva aneurysms are rare, with an incidence of 0.1% to 3.5% of all congenital heart defects. This article reports the case of a patient with trisomy 13 with a new systolic murmur found to have a ruptured sinus of Valsalva aneurysm diagnosed on coronary computed tomography angiography. This is the first case to report sinus of Valsalva aneurysm rupture secondary to Streptococcus viridans endocarditis in a patient with trisomy 13 syndrome and highlights the importance of coronary computed tomography angiography in noninvasive imaging and surgical planning., (© 2023 by the Texas Heart® Institute, Houston.)

Anomalous origin of the left coronary artery from the opposite sinus of Valsalva with an intramural aortic course (L-ACAOS-IM) can cause syncope, sometimes as a prodrome of lethal events, including sudden cardiac death, in young athletes. The detailed mechanism of syncope in patients with L-ACAOS-IM is still unclear. This case report describes a 17-year-old boy who presented to the hospital because of syncope following chest pain with increasing frequency during exercise, such as playing soccer and running. In a treadmill exercise test, a decrease in blood pressure was seen (from 99/56 mm Hg to 68/38 mm Hg); chest pain and faintness accompanied by ST-segment elevation in lead aVR and ST-segment depression at other leads on electrocardiography were noted. These findings and symptoms disappeared spontaneously within a few minutes while clinicians prepared for emergency medications. Coronary computed tomography angiography (CCTA) showed that the origin of the left coronary artery (LCA) was the opposite sinus of Valsalva, and the course of the LCA was through the aortic wall toward the left coronary sinus. He was diagnosed with L-ACAOS-IM. After surgical treatment by unroofing the intramural part of the LCA and reconstructing a neo-ostium, he no longer experienced syncope during exercise. This case suggests that low cardiac output caused by myocardial ischemia, not life-threatening arrythmia, is a main mechanism of syncope in patients with L-ACAOS-IM. Consideration should be given to performing CCTA before an exercise stress test for young patients with syncope and chest pain to avoid the risk of severe myocardial ischemia., (© 2022 by the Texas Heart® Institute, Houston.)

Anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS) are a challenge because of their various anatomic and clinical presentation. Although the prevalence is low, the absolute numbers of detected ACAOS are increasing because of the growing use of noninvasive anatomical imaging for ruling out coronary artery disease. As evidence-based guidelines are lacking, treating physicians are left in uncertainty for the optimal management of such patients. The sole presence of ACAOS does not justify surgical correction, and therefore a thorough anatomic and hemodynamic assessment is warranted. Invasive and noninvasive multimodality imaging provides information to the clinical question whether the presence of ACAOS is an innocent coincidental finding, is responsible for the patient's symptoms, or even might be a risk for sudden cardiac death. Based on recent clinical data, focusing on the pathophysiology of patients with ACAOS, myocardial ischemia is dependent on both the extent of fixed and dynamic components, represented by anatomic high-risk features. These varying combinations should be considered individually in the decision making for the different therapeutic options. This state-of-the-art review focuses on the advantages and limitations of the common contemporary surgical, interventional, and medical therapy with regard to the anatomy and pathophysiology of ACAOS. Further, we propose a therapeutic management algorithm based on current evidence on multimodality invasive and noninvasive imaging findings and highlight remaining gaps of knowledge.

Tumours or tumour-like lesions around the aortic valve are relatively rare and are difficult to diagnose. We report an interesting case of calcified thrombi in the Valsalva sinuses and coronary cusps that mimicked an aortic valve tumour. A 68-year-old man presented with a 20-mm calcified mass in the non-coronary and left-coronary cusps extending to their corresponding Valsalva sinuses, which was detected by echocardiography and contrast-enhanced computed tomography. The lesions were resected to establish the diagnosis and prevent systemic embolization. Intraoperative and histopathological examination revealed an atrophied non-coronary leaflet and calcified atherosclerotic lesions of the Valsalva sinuses and contiguous parts of the cusps, with ulceration and fibrin thrombi. The lesions were resected and aortic valve replacement was performed to avoid aortic valve dysfunction. The patient's atrial fibrillation was controlled, and anticoagulants were discontinued 3 months postoperatively. Surgery to establish the diagnosis and to prevent systemic thromboembolism was thought to be reasonable, even in the absence of valvular dysfunction., (© The Author(s) 2022.

In the complex spectrum of coronary anomalies, the origin of the left coronary artery from the right sinus of Valsalva with intramural course could represent a catastrophic life-threatening condition leading to extensive myocardial infarction and sudden cardiac death, especially in young athletes. We report the case of a young female athlete with anomalous left coronary artery from the opposite sinus who survived a major non-ST-elevation myocardial infarction during the eighth kilometer of a running race. It was successfully treated by creating a neo-ostium of the left coronary artery in the left sinus at the point at which the artery left the aortic wall., (© 2022 by the Texas Heart® Institute, Houston.)

A 74-year-old female with previous permanent pacemaker insertion for complete heart block and no history of connective tissue disease presented to our regional cardiothoracic center with progressive exertional shortness of breath. Nine years later, when the patient was 83 years old, a computed tomography scan of the thoracic aorta revealed an isolated aneurysm of the aortic root measuring 7.6 × 5.1 cm at the sinus of Valsalva., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2022 The Author(s).)

Percutaneous intervention in anomalous coronary arteries originating from the opposite sinus of Valsalva is complicated by their unusual location and course, which makes selective cannulation difficult. The GuideLiner (Vascular Solutions, Inc.) is a monorail guide extension catheter designed to advance beyond the tip of a mother guide catheter to enable deep intubation of a coronary artery, provide extra support, and improve coaxial alignment. We describe the cases of 4 patients with an anomalous coronary artery originating from the opposite sinus of Valsalva-including 2 with acute myocardial infarction-who underwent successful percutaneous coronary intervention with use of a GuideLiner catheter., (© 2022 by the Texas Heart® Institute, Houston.)

It is uncommon for the left anterior descending coronary artery to arise from the contralateral Valsalva sinus, and more of a rarity to see coexistent left main coronary artery anomaly. Our patient reported normal daily physical activity and denied further evaluation (stress test, scintigraphy) or cardiothoracic consultation. She continues to be symptom free at 1-month follow-up.

Sinus of Valsalva aneurysm is a very uncommon clinical finding and often requires emergency surgery due to its high risk of rupture. This educational text reports the case of a 91-year-old Italian women who was incidentally discovered to have a huge double aneurysm of the sinuses of Valsalva.

Background: Sinus of Valsalva aneurysm (SVA) is a rare congenital disease that can cause severe clinical presentations when the aneurysm ruptures. Here, we report a rare case of a noncoronary sinus of Valsalva aneurysm with rupture into the right atrium., Case Presentation: A 14-year-old Chinese female patient presented viral myocarditis with acute heart failure at the local hospital, and she was finally diagnosed with a noncoronary sinus Valsalva aneurysm with rupture into the right atrium by digital subtraction angiography with cardiac catheterization angiography and echocardiography at our hospital (Children's Hospital of Chongqing Medical University). Percutaneous closure intervention was performed shortly after her diagnosis, and the patient showed good functional recovery., Conclusions: We report a case of ruptured sinus of Valsalva aneurysm successfully treated by percutaneous closure, which is an excellent alternative treatment., (© 2022.

Acute chest pain is a leading cause of emergency department (ED) visits in the adult population. However, patients with a life-threatening cause of chest pain comprise only a small fraction, hence identification of those who need immediate intervention is very important. One rare cause is rupture of the aneurysm, which may present with a wide variety of symptomatology, including anginal chest pain. In a busy ED, evaluation of chest pain suggestive of myocardial ischaemia needs to cater to early identification of acute coronary syndrome (ACS), limit over investigating patients for low or intermediate probability of ACS and appropriate decision making for discharge, to reduce ED over boarding. Validated scores for evaluating the low or intermediate probability chest pain like the HEART pathway may miss such rare diagnoses in the absence of ECG changes, requiring high degree of suspicion and individualisation of patient care., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022.

Background: Contained rupture of the ascending aorta is a rare condition, but the severity of this complication enforces strict guidelines for its prevention and a prompt diagnosis, once already occurred., Case Presentation: A 66-year-old man with a history of type 2 diabetes, longstanding aortic valve stenosis and aortic root aneurysm of 47 mm was hospital admitted for elective surgery. A Bentall-De Bono procedure was performed in order to replace the stenotic bicuspid aortic valve and exclude the dilated portion of the aortic wall. Intraoperatively, a discontinuity of the aortic wall, just above the aortic annulus, at the non-coronary sinus of Valsalva was incidentally observed. The aortic wall discontinuity was none other than a contained aortic rupture. The preoperative CT-scan images were afterwards analyzed by the radiologist, in order to identify the contained aortic rupture. Indeed a false aneurysm of the non-coronary sinus of Valsalva of a maximum diameter of 15 mm was detected, thanks to a 3D reconstruction., Conclusions: The diagnosis of contained aortic rupture is certainly demanding, particularly in absence of signs or symptoms of rupture in a chamber of the heart or in the pericardium. Although this case represents a consensus of experts' opinion, the recognition of these specific cases in which the risk of dissection, rupture or death is at its highest, would allow to operate at the appropriate time, improving the outcomes., (© 2022.
