Atrial fibrillation (AF) is the most common complication, but repair procedures in adults remain unestablished.Case presentation: A 49-year-old woman had cor triatriatum sinister (Lucas-Schmidt classification type I-A) with moderate mitral regurgitation and atrial fibrillation. Communication between the accessory chamber and the main chamber was established via a 10-mm fenestration with a pressure gradient of 14 mmHg. Mitral valve repair and the maze procedure, via radiofrequency ablation, was done after complete resection of the anomalous septum in the left atrium. Mitral regurgitation was well-controlled and atrial fibrillation disappeared. Sinus rhythm has been continually maintained at 6 months post-surgery, with no mitral regurgitation recurrence.Conclusions: Here, a rare adult cor triatriatum case with simultaneous mitral valve regurgitation and atrial fibrillation was treated with good results. The maze procedure shows effectiveness for atrial fibrillation associated with cor triatriatum. Especially the anomalous membrane attachments must be resolved in addition to the conventional maze procedure because electrical mapping of Cor triatriatum sinister showed low-voltage zones at the membrane attachments and it cause macro-reentrant atrial tachycardia.","PeriodicalId":520286,"journal":{"name":"General Thoracic and Cardiovascular Surgery Cases","volume":"4 1","pages":"22"},"PeriodicalIF":0.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preoperative echocardiography revealed severe mitral regurgitation and a highly mobile mass on the posterior leaflet. The prosthetic valve had thickened cusps without regurgitation. Emergent surgery was performed to explant the prosthetic valve and replace both the aortic and mitral valves through a re-median sternotomy under routine cardiopulmonary bypass support. The textured sealing cuff was detached from the surrounding tissue after separating the rigid outflow portion from the transformable inflow portion by cutting the fabric. No annular or sub-annular damage was observed. Enterococcus faecalis was cultured from the blood. The patient received 6 weeks of antimicrobial therapy and was discharged without symptoms of heart failure or infection.Conclusion: The patient successfully underwent valve explantation and double valve replacement for prosthetic valve endocarditis.

We performed radical pulmonary resection under 3-port video-assisted thoracic surgery (VATS) in a patient with primary lung cancer and IDPA.Case presentation: A 61-year-old man presented with an abnormality identified on chest X-ray during a medical check. Computed tomography revealed a 56-mm pulmonary tumor (diagnosed as squamous cell carcinoma by bronchoscopy) located in S6 of the right lower lobe, with clinical middle and lower interlobular lymph node metastasis on the basis of lymphadenopathy. Moreover, the right and left main pulmonary arteries were dilated, but the common basal artery after branches A4, A5, and A6 was normal. The presence of pulmonary hypertension was ruled out by cardiac catheterization, which revealed a pulmonary artery pressure within the normal range (24/11 mmHg). No infectious disease was present, and the patient did not have any history of chronic inflammatory disease. Therefore, IDPA was diagnosed. Surgery was performed, and the intraoperative findings were consistent with those of preoperative CT. Although there were concerns that the pulmonary artery wall might have been weakened due to IDPA, all pulmonary arteries, including the dilated right intermediate trunk, were cut safely with a stapler in this case.Conclusion: In this case, the intraoperative and histopathological findings demonstrated no fragility of the pulmonary arteries, and the pulmonary artery was safely dissected using a stapler in 3-port VATS. However, radical surgery for lung cancer with IDPA is rare, and the safety needs to be verified by accumulating of further cases in the future.","PeriodicalId":520286,"journal":{"name":"General Thoracic and Cardiovascular Surgery Cases","volume":"4 1","pages":"17"},"PeriodicalIF":0.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11921669/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665823","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}

During the 19 h between NGT replacement and the first observation of respiratory failure, tube feedings were administered twice via the new NGT. Computed tomography revealed NGT misinsertion into the left lower lobe bronchus and massive liquid accumulation with pneumothorax in the left pleural cavity, suggesting a penetrating bronchopulmonary trauma. After the patient was transferred to our hospital, a chest tube was inserted immediately to drain the contents of the tube feeding that had accumulated in the pleural space. Several days later, surgery was performed to irrigate the empyema cavity and repair the laceration.

The pericardial defect was approximately 10 × 6 cm and was reconstructed with a 0.1-mm polytetrafluoroethylene sheet. Routine chest radiographs taken just after the operation were normal.

PVL is linked to an increased risk of long-term mortality; however, there is no consensus on its treatment.Case presentation: Case 1: A 76-year-old female with severe aortic stenosis underwent RDAVR via median sternotomy. Intraoperative transesophageal echocardiography (TEE) revealed moderate PVL at the left-noncoronary cusp commissure. Three horizontal mattress stitches were applied from outside the aorta through the prosthetic sewing cuff to address the PVL site; however, the leak persisted. It was noted that the balloon-expandable sealing frame was slightly protruding inward at a location corresponding to the PVL site. Accordingly, balloon dilatation was performed under direct vision, and the PVL resolved. Postoperatively, no conduction disorders were observed. At the 24-month follow-up, echocardiography showed no recurrence of PVL. Case 2: A 78-year-old male with severe aortic stenosis underwent RDAVR in a standardized fashion. Intraoperative TEE revealed moderate PVL at the right coronary cusp side. The balloon-expandable sealing frame was found not to have fully expand outward at the PVL site. Balloon dilatation was therefore performed as in Case 1, successfully resolving the PVL. No postoperative conduction disorder was encountered. At the 12-month follow-up, echocardiography revealed no recurrent PVL.Conclusions: Direct intraoperative re-ballooning is a potentially effective option for addressing intraoperatively identified PVL after RDAVR.","PeriodicalId":520286,"journal":{"name":"General Thoracic and Cardiovascular Surgery Cases","volume":"4 1","pages":"13"},"PeriodicalIF":0.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11892181/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143598741","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}
