[Surgical Repair for Right Ventricular Perforation due to Leadless Pacemaker Implantation:Report of a Case].1 week agoAn 87-years-old woman with a history of right mastectomy for breast cancer, currently undergoing chemotherapy for multiple metastasis via a central venous catheter placed in the left subclavian vein, presented with bradycardia and dyspnea. Electrocardiogram revealed a 2:1 atrioventricular block. Implantation of a leadless pacemaker (LLPM) was planned for the patient. During implantation, right ventricular rupture occurred. Percutaneous cardiopulmonary support was initiated immediately. Subsequently, emergency surgery was performed. LLPM is considered a useful and safe device;however, serious complication, such as cardiac injury, have been reported in a small number of cases. Thorough risk assessment and preparation for complication, including cardiac surgery, may be life-saving.Cardiovascular diseasesAccess

[Staged Endovascular Aortic Repair for Thoracoabdominal and Aortic Arch Aneurysms].1 week agoIn recent years, endovascular aortic repair has become one of the standard treatments for aortic aneurysms. However, when the aneurysm involves the branches of the abdominal aorta or the aortic arch, the procedure becomes more complex and often necessitates surgical reconstruction of the involved branches. To address these challenges, the use of physician-modified endografts in which fenestrations are manually created by physicians has been reported. This approach, known as fenestrated and branched endovascular aortic repair, involves the placement of small-diameter bridging stent grafts through the fenestrations, and its utility has recently been highlighted. Herein, we report a case of successful fenestrated and branched endovascular aortic repair using physician-modified endografts in a patient with both thoracoabdominal and aortic arch aneurysms.Cardiovascular diseasesAccess

[Surgical Outcomes of Stanford Type A Acute Aortic Dissection in the Patients Aged 85 Years or Above].1 week agoThis retrospective analysis assessed surgical outcomes in patients aged 85 years or older who underwent emergency open thoracic aortic surgery for acute Stanford type A dissection between 2012 and 2025. Among 352 patients, 27 were classified as very elderly. Compared to younger cohorts, this group exhibited a higher prevalence of DeBakey typeⅡ dissection and thrombotic false lumen occlusion, with a lower incidence of malperfusion. The majority underwent hemiarch replacement. In-hospital mortality was low at 3.7%, and postoperative complication rates were comparable to the control group. Due to slow functional recovery, the proportion of patients discharged directly home was reduced. Despite a limited follow-up rate, three-year outcomes-including overall survival (77.4%), freedom from aortic-related mortality( 91.7%), and distal reoperation-free survival( 91.7%)-were favorable. The implementation of advanced techniques, such as staged thoracic endovascular aortic repair (TEVAR) and zone 0 TEVAR utilizing the retrograde in-situ branched stent graft (RIBS) method, effectively minimized the necessity for reintervention via thoracotomy or laparotomy. These findings underscore the clinical viability of surgical intervention in selected very elderly patients, notwithstanding inherent limitations such as referral bias and incomplete longitudinal data.Cardiovascular diseasesAccessCare/ManagementAdvocacy

[Early Outcomes of Total Arch Replacement Using an Integrated Frozen Elephant Trunk for Acute Type A Aortic Dissection].1 week agoIn Japan, surgical repair for Stanford type A acute aortic dissection(AAAD)has been increasingly performed, accompanied by gradual improvement in early outcomes, While ascending or hemiarch replacement remains the mainstream strategy, late aneurysmal dilatation of the residual dissected aorta is still a concern, The frozen elephant trunk(FET)technique, which facilitates aortic remodeling, has been increasingly adopted in AAAD surgery, Since the introduction of a domestic integrated four-branched FET device in late 2022, expectations have risen for improved procedural safety and simplicity, We report our early institutional outcomes of total arch replacement(TAR)using the integrated four-branched FET, Methods:Among 211 AAAD cases treated between December 2022 and April 2025, 110 underwent TAR with FET, of which the first 50 consecutive cases using the integrated four-branched FET[FROZENIX 4 Branched(FZX4B)]were retrospectively analyzed, The primary endpoint was early postoperative outcome, including mortality and spinal cord ischemia(SCI), Secondary endpoints included midterm survival, freedom from aortic events, and morphologic changes in the descending aorta, Results:The median age was 65 years[interquartile range(IQR):56~74], and 29 patients(58%)were male, The median operative time was 372 minutes(IQR:315~506), and the hypothermic circulatory arrest time was 42 minutes(IQR:38~50), The distal anastomosis was performed in zone 3 in 84% of cases, The FZX4B diameter most used was 25 mm(60%), In-hospital mortality was 4%, SCI occurred in one patient(2%), Two patients(4%)required additional thoracic endovascular aortic repair(TEVAR)for FET stenosis, The median follow-up was 248 days(IQR:165~472), Overall survival was 93% at 1 year and 86% at 2 years, and freedom from aortic events was 87% and 81% at 1 and 2 years, respectively, The FET distal level was mainly at Th6(62%), The aortic diameter at the distal edge of the FET decreased from 30 mm(IQR:28~33)preoperatively to 27 mm(25~31)at 1 year(p<0.001), The FET tip diameter correlated with the preoperative outer diameter at the anastomotic site(r=0.66, p<0.001), Conclusions:Although FET-related stenosis should be recognized as a potential procedural risk, TAR using the integrated FET for AAAD achieved acceptable early outcomes, A larger comparative study with conventional repair is warranted to elucidate its statistical impact.Cardiovascular diseasesAccessAdvocacy

[Conservative Management of Stanford Type A Acute Aortic Dissection].1 week agoEmergency surgery remains the standard of treatment for acute Stanford type A aortic dissection(AAAD), Nevertheless, in real-world practice a minority of patients do not undergo immediate surgery due to clinical constraints, We sought to delineate the outcomes and practical limits of such nonoperative management under strict protocols, Methods:Of 668 consecutive AAAD patients(Jan 2019~Mar 2025), we retrospectively analyzed 100 who did not receive immediate surgery after excluding 13 with cardiopulmonary arrest, Patients were stratified into a criteria group(C;thrombosed/occluded false lumen in the ascending aorta with ascending diameter≦50 mm and false lumen≦11 mm;n=59)and a non-criteria group(NC;outside these criteria;n=41), The primary endpoint was in-hospital mortality;secondary endpoints included aortic-related death, post-discharge events, and associations with imaging/clinical indices, Results:NC patients were older and more often female, with larger ascending aortas and false lumens(both p<0.001), In-hospital mortality was 31.7% in NC vs 1.7% in C(p<0.001);48-hour mortality in NC was 12.2%, and aortic-related deaths clustered within 4.56±2.99 days(range 1~12), Seven patients underwent delayed surgery for imaging changes;all survived, Discharge alive occurred in 98.3%(C)and 68.3%(NC), Among those discharged alive, survival up to 2 years was similar, Low body mass index(BMI)and hemodynamically significant tamponade were associated with in-hospital death in NC, Conclusions:These data support surgery as the default strategy for AAAD, When surgery is unavoidably deferred, conservative management should be considered only in strictly selected patients, with early hemodynamic/computed tomography(CT)triggers for conversion, In NC patients, the first hospital week is the highest-risk window, and low BMI or tamponade should prompt heightened vigilance and a low threshold for intervention.Cardiovascular diseasesAccessCare/ManagementAdvocacy

Systemic α₂-agonist use and lower hazard of glaucoma compared with β-blockers: a cohort study.1 week agoSystemic antihypertensive medications may influence glaucoma-related outcomes through intraocular pressure-dependent and vascular mechanisms. While topical α₂-agonists are established glaucoma therapies, the association between systemic α₂-agonists and glaucoma hazard remains unexamined; we compared their hazard with systemic β-blockers in adults with hypertension.
We conducted a multicentre retrospective cohort study using deidentified electronic health records. Adults aged ≥40 years with hypertension and chronic exposure to systemic α₂-agonists or β-blockers were included. Patients with pre-existing ocular hypertension (OHT), primary open-angle glaucoma (POAG), concomitant comparator use, or inadequate ophthalmic follow-up were excluded. We balanced cohorts using propensity score matching (PSM) and assessed the hazard of OHT and POAG at 1, 3, and 5 years. Cox models estimated adjusted HRs (aHRs) with 95% confidence intervals (CIs).
Patients treated with α₂-agonists (n=4186) were matched to those treated with β-blockers (n=360 399), resulting in 4152 patients per group after PSM. In Cox models (on the unmatched cohorts) adjusted for demographics, comorbidities, medications, laboratory and biometric measures, socioeconomic indicators and selected procedures, α₂-agonist exposure was associated with a lower hazard of OHT (aHR (95% CI) 0.582 (0.473 to 0.716), 0.559 (0.468 to 0.669) and 0.534 (0.450 to 0.634)) and POAG (aHR (95% CI) 0.359 (0.300 to 0.429), 0.333 (0.282 to 0.392) and 0.334 (0.286 to 0.390)) at 1-year, 3-year, and 5-year follow-up, respectively (all p<0.001).
Systemic α₂-agonist use was associated with a substantially lower hazard of glaucoma-related diagnoses compared with systemic β-blocker use. These findings are limited by the observational design, potential residual confounding, and reliance on diagnostic coding. These results warrant further investigation in prospective mechanistic studies and randomised clinical trials.Cardiovascular diseasesAccessCare/ManagementAdvocacy
