Paravalvular abscesses constitute a rare complication of IE, resulting from extending IE beyond the valve annulus, less commonly caused by Klebsiella species. This complication is more common in prosthetic valves, particularly bioprosthetic valves.Case summary: We describe a 75-year-old woman with Churg-Strauss syndrome and diabetes mellitus who underwent surgical replacement of bioprosthetic aortic and mitral valves 11 years ago. One year ago, she had a transcatheter mitral ViV procedure due to bioprosthetic mitral valve degeneration. The patient was referred to our centre with fatigue and fever, alongside elevated white blood cell count, erythrocyte sedimentation rate, and C-reactive protein. Blood and urine cultures tested positive for Klebsiella oxytoca. Echocardiographic assessments revealed a paravalvular abscess (13 × 8 mm) in the posterolateral side of the bioprosthetic mitral valve, fistulized into the left ventricle. The patient received treatment with vancomycin, meropenem, and colistin and was a candidate for surgery. Eleven days after the patient's admission, she passed away.Discussion: This study underscores the novelty of IE complicated with paravalvular abscess following the ViV procedure. In such cases, a multidisciplinary approach and timely surgical interventions are crucial for optimal patient outcomes.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 1","pages":"ytaf013"},"PeriodicalIF":0.8,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11770396/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052056","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}

Here, we present a rare case in which the Navitor (Abbott Structural Heart, Santa Clara, CA, USA) could not be recaptured.Case summary: An 81-year-old Japanese woman with very severe aortic stenosis and a massively calcified nodule at the non-coronary cusp (NCC) underwent TAVI with a 25 mm Navitor valve. During the initial deployment attempt, non-uniform expansion (NUE) was observed on the NCC side when the valve was 80% deployed. An attempt was made to recapture and reposition the valve, but the delivery system capsule failed to fully re-sheath the prosthesis, leaving approximately one-third of the valve outside the capsule and preventing complete recapture. The Navitor was promptly redeployed while still within the basal ring. Following redeployment, the NUE resolved, and the valve was successfully positioned 3 mm below the basal ring on the NCC side and 4 mm below the left coronary cusp. We hypothesized that interference between the capsule tip and the calcified nodule on the NCC leaflet inhibited the re-sheathing process.Conclusion: This report documents a rare complication involving the failure to recapture the Navitor valve. In cases with large calcified nodules on the leaflet, caution is essential during the re-sheathing process. We strongly recommend re-deploying the prosthesis rather than attempting to remove it from the basal ring to minimize procedural risks and ensure proper valve placement.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 1","pages":"ytaf015"},"PeriodicalIF":0.8,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11770386/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052060","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}

Although the sequential dilation technique has been proposed as the mainstream technique for transseptal puncture with ASD occluder, it is associated with substantial risks and technical difficulties.Case summary: We report a patient who underwent catheter ablation for atrial fibrillation and had a large ASD occluder. A balloon was dislodged into the patient's right superior pulmonary vein (RSPV) during a transseptal puncture and was successfully captured. The most notable feature of this case was the dislodgement of the dilation balloon, which has not been reported previously.Discussion: Repeated and gradual dilation of the pathway with a pressure balloon is unavoidable during the establishment of the left atrial channel. It is not recommended to choose a coronary balloon and Run-through guidewire. Since only the tip of the coronary balloon is connected to the guide wire, it cannot stably guide the balloon through the puncture hole. When using over-the-wire balloon or peripheral vascular balloon, the balloon can stably attach to the guide wire as a whole, which allows movement along the puncture hole. The puncture hole can be safely expanded using a peripheral vascular balloon combined with a loach guidewire in subsequent expansion. In addition, it is important to avoid violent manipulation. After confirming the dislodgement of the balloon, it is imperative to remove it. Relying solely on oral anticoagulation may not sufficiently decrease the risk of thrombosis.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 1","pages":"ytaf014"},"PeriodicalIF":0.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11775611/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143064694","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}

Active fixation Quadripolar leads (Attain Stability™ Quad 4798, Medtronic) can expand choice to CS branches with limited access; however, no cases of anchoring to the main body of the CS have been published to date.Case summary: We describe a case of cardiac resynchronization therapy pacemaker upgrade in a 79-year-old female who developed pacing-induced cardiomyopathy after pacemaker implantation via the right superior vena cava (SVC) for atrioventricular block eight years ago wherein PLSVC was revealed during the procedure. Retrograde giant CS angiography via SVC confirmed the lateral vein ostium. Attain Stability Quadripolar lead was selected; however, due to the tortuousness and stenosis of the target vein, the proximal electrodes could not advance into the target vein. Therefore, the side helix between the third and fourth electrodes was crimped to the anterior wall of the giant CS using the distal end curve of the subselection catheter and successfully screwed into the main body of the CS. At more than 6 months, left ventricular ejection fraction improved without lead dislodgement.Discussion: Fixation of CS lead to the main body of the dilated CS was feasible by devising a guiding catheter and a subselection catheter. Nevertheless, the safety of active fixation lead retraction after long-term indwelling in CS is unknown and it should be carefully considered.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 1","pages":"ytaf008"},"PeriodicalIF":0.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11770388/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052058","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}

Approximately 10% of patients with AF have epicardial connections (ECs) between the atrium and PV inside the PV isolation lines, which are associated with AF recurrence. However, the contribution of EC(s) between the SVC and right atrium (RA) to subsequent AF remains unknown.Case summary: A 76-year-old woman underwent ablation for recurrent AF. She had undergone cryo-balloon ablation for paroxysmal AF 3 years previously. After confirming the complete entrance and exit blocks of the four PVs, SVC firing-induced AF was observed. After SVC isolation, the EC between the SVC and RA was observed. No AF was induced after EC ablation.Discussion: Although the mechanisms of ECs in the SVC and RA have not been entirely elucidated, several potential mechanisms have been proposed. (i) Anatomically inherited myofibres/bundles may run through the epicardial side between the SVC and RA. (ii) Epicardial connections between the right PV and the SVC or RA have been recently reported. Thus, we might speculate on the possibility of the existence of EC(s) between the right PV and both the SVC and RA. After cryoablation in the first session, the connection between the SVC and RA remained, which might have acted as EC(s). Thus, physicians should consider the possibility of EC(s) when remaining potentials in the SVC are observed, even though the SVC isolation line seems to be completed.","PeriodicalId":11910,"journal":{"name":"European Heart Journal: Case Reports","volume":"9 1","pages":"ytaf016"},"PeriodicalIF":0.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11770597/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052057","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}
