Contrast-induced encephalopathy (CIE) is also a rare but severe complication associated with the use of iodinated contrast agents during various cardiovascular and neurovascular procedures. Its occurrence during ablation, particularly AF ablation, remains unreported.Case summary: We report a case in which CASs and/or CAEs associated with ST-segment elevation were observed, accompanied by worsening haemodynamics during AF cryoablation. Insertion of an intra-aortic balloon pump improved the haemodynamics. Following anaesthesia recovery, he developed verbal/expressive aphagia and left-sided hemiplegia. However, emergent cerebrovascular angiography revealed no cerebral artery occlusions or haemorrhage. Plain computed tomography (CT) showed diffuse cortical hyperdensity in the right temporal and both occipital lobes on Day 0, brain swelling by Day 2, and complete radiological recovery by Day 4. His symptoms, except for a slight grip drop of the left hand, improved by Day 4, leading to a diagnosis of CIE.Discussion: The key step of CIE may be attributed to a blood-brain barrier breakdown, which is influenced by multiple factors, including the direct chemotoxicity and hyperosmolarity of the contrast agent, ischaemic stroke (including cerebral vasoconstriction), and anaesthesia. Thus, physicians should consider the possibility of CIE when a patient exhibits neurological abnormalities during ablation, despite a lack of a CIE history with contrast-enhanced CT.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 9","pages":"ytaf413"},"PeriodicalIF":0.8,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12418943/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145039440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have developed an innovative auxiliary support technique utilizing a dual guide extension catheter system, designed to enhance safety and facilitate deep coronary artery access.Case summary: A male in his sixties who presented with chest pain was diagnosed with non-ST elevation myocardial infarction. Percutaneous coronary intervention failed to achieve complete revascularization due to the presence of extensive chronic total occlusion (CTO) in the right coronary artery (RCA). A staged percutaneous intervention was performed to treat the tortuous CTO lesion. Dual guide extension catheters (DGEC), consisting of a 6 Fr Guideplus™ in the 8 Fr GuideZilla II™, were introduced. The Guideplus™ was deeply inserted into the distal RCA through the GuideZilla II™ support. This system provided a stable catheter platform, enabling successful negotiation of the guidewire and delivery of the catheter across the extensive, markedly tortuous segment of CTO of the RCA. Thereafter, the RCA was completely recanalized through stenting and balloon angioplasty following antegrade guidewire penetration. Subsequently, enhanced backup force of the DGEC was demonstrated through in vitro force gauge testing, suggesting that this novel technique might be promising for interventions for CTO in vessels with severe tortuosity.Discussion: The DGEC system facilitates substantial guide catheter backup support in the context of PCI for severely tortuous total occlusive disease.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 9","pages":"ytaf412"},"PeriodicalIF":0.8,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12412445/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145014165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The underlying pathoanatomical substrate includes replacement of cardiomyocytes by fibrous tissue, leading to extensive myocardial fibrosis of the posterolateral wall of the left ventricular (LV) epicardium. Cardiac arrhythmias, including ventricular tachycardia (VT), are common in this condition, particularly when LV ejection fraction (LVEF) declines.Case summary: A 45-year-old male with dilated cardiomyopathy due to BMD presented for routine follow-up of his implantable cardioverter defibrillator (ICD). Device interrogation revealed multiple episodes of sustained VT, some terminated by antitachycardia pacing. Echocardiogram showed a mildly dilated LV with LVEF of 30%. In April 2024, he experienced an appropriate ICD shock for sustained VT, and substrate ablation was scheduled. Relying on predominant epicardial fibrosis known to BMD, a direct epicardial approach was performed and electroanatomical mapping (EAM) of the posterobasal LV revealed a large area of delayed, fractionated, and low-voltage electrograms (EGMs). Extensive ablation was performed with meticulous application near the atrioventricular annulus and left phrenic nerve region. Repeat EAM showed near-complete abolition of delayed potentials. No endocardial ablation was performed. Ventricular tachycardia remained non-inducible, and no sustained episodes or ICD shocks have been recorded during the 9-month follow-up.Discussion: Direct epicardial access may be the preferred ablation strategy for some cardiomyopathies such as BMD, where the arrhythmic substrate is epicardial. Detailed EAM with annotation of abnormal EGMs is crucial before ablation, and special care must be taken to avoid injury to critical structures such as the phrenic nerve or coronary arteries.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 9","pages":"ytaf406"},"PeriodicalIF":0.8,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12405761/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early diagnosis and treatment are crucial for effective management.Case summary: We herein report the case of a 33-year-old male patient who presented to the Emergency Department with fever and chest pain after returning from a journey from a tropical region in Centre America. Initial tests showed elevated high-sensitivity troponin T (Hs-TnT) levels, suggesting possible cardiac involvement, but EKG and chest X-ray were normal. Echocardiography detected hypokinesis of the interventricular septum and a small pericardial effusion. Cardiac magnetic resonance (CMR) showed left ventricular function at lower normal limits and a small pericardial effusion, but also masses in the lungs and mediastinum, confirmed by computed tomography. Biopsy was performed, and histology revealed disseminated histoplasmosis. The patient was treated with antifungals and was discharged after two weeks, continuing antifungal administration in the outpatient clinic for 18 months. Follow-up imaging showed significant reduction of the masses. The patient remained asymptomatic with no further treatment needed.Discussion: In this case report, we emphasize the essential role of a multimodal imaging approach in diagnosing cardiac inflammatory diseases. CMR was pivotal providing a three-dimensional perspective of the mediastinum, which led to the identification of a retrocardiac mediastinal mass that might have otherwise gone undetected. This highlights the importance of integrating multimodality imaging techniques to improve diagnostic accuracy and guide effective treatment strategies.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 9","pages":"ytaf408"},"PeriodicalIF":0.8,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12418945/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145039520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a case of a patient on ECMO support and with comorbid Marfan's syndrome who was finally diagnosed with FM after computed tomography angiography (CTA) differentiated between FM, coronary artery disease, and aortic root dilation.Case summary: An 18-year-old male with suspected Marfan's syndrome presented to our hospital with sudden onset of anterior chest pain without obvious trigger with nausea and vomiting for 10 h, supported by ECMO. His laboratory tests showed leucocytosis, elevated troponin, and creatine kinase. The electrocardiogram showed acute high lateral and extensive anterior wall myocardial infarction. On the second day of admission, he underwent CTA to rule out extensive aortic coarctation and coronary stenosis and found inhomogeneous enhancement of the myocardium and abnormal patchy enhancement of the epicardium, which was considered to be FM. The patient was then treated with methylprednisolone and human immunoglobulin, and his symptoms and laboratory markers improved markedly after a few days.Discussion: The diagnostic process in this case highlights the challenge of recognizing FM in the context of complex cardiovascular disease.

In such anatomically sensitive regions, the use of radiofrequency (RF) energy may carry a risk of collateral injury or prove ineffective. We present a case report describing successful ablation of infundibular PVCs using pulsed field ablation (PFA).Case summary: A 38-year-old female with highly symptomatic, monomorphic PVCs was referred for repeat ablation following a previously ineffective procedure performed with RF energy. Intracardiac mapping localized the earliest ventricular activation to the medial free wall infundibulum of the RVOT. A series of high-power RF applications were delivered at the site of earliest activation; however, elimination of PVCs was not achieved. Given the ineffectiveness of RF ablation, the procedure was continued using PFA. A series of focal-bipolar PFA applications were delivered at the RVOT infundibulum target site. This resulted in complete elimination of PVCs. The procedure was completed without complications. At 4-month follow-up, the patient remained asymptomatic, and 24-h Holter monitoring confirmed the complete absence of PVCs.Discussion: This case demonstrates the feasibility of focal-bipolar PFA for PVCs arising from the RVOT infundibulum. Pulsed field ablation may offer a safe and effective alternative in anatomically challenging locations, particularly when conventional thermal energy sources are unsuccessful.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 9","pages":"ytaf398"},"PeriodicalIF":0.8,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12412440/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145014233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cardiovascular complications include increased cardiac output, which promotes the onset of heart failure and the development of pulmonary hypertension (PAH), significantly impairing the quality of life due to severe functional class deterioration. However, these complications are currently treatable by ligation or removal of malformations.Case report: A 33-year-old male with a long-standing, progressively enlarging AVM of the right upper limb presented with necrosis and haemorrhage, leading to hypovolemic shock. Angiography revealed an AVM involving the subclavian, axillary, and brachial arteries, necessitating embolization and surgical interventions. Six years later, he developed distal finger necrosis, requiring infracondylar amputation. He later presented with stump infection, purulent discharge, orthopnoea, jugular venous distension, a loud second heart sound, and a holosystolic murmur in the tricuspid region. Echocardiography and catheterization confirmed PAH and a high-flow arteriovenous fistula. Multidisciplinary evaluation led to definitive amputation and PAH treatment. Postoperatively, PAH resolved, and the patient was discharged with ongoing follow-up, showing significant improvement.Discussion: This case report highlights the importance of a multidisciplinary approach in managing PWS, especially when endovascular interventions are not feasible owing to the diffuse nature of the AVM. It also emphasizes the potential for reversing severe complications through definitive surgical intervention in complex cases of PWS.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 9","pages":"ytaf381"},"PeriodicalIF":0.8,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12404289/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
