Aim: To describe the clinical results of combined Ahmed valve implantation and 23-gauge vitrectomy for medically uncontrolled neovascular glaucoma (NVG) secondary to proliferative diabetic retinopathy (PDR).
Methods: The medical records of medically uncontrolled NVG patients with PDR who underwent Ahmed valve implantation and 23-gauge vitrectomy between March 2016 and December 2018 were reviewed. Enrolled patients had at least 6-month follow-up. Panretinal photocoagulation (PRP), anti-vascular endothelial growth factor, surgery and medication history were documented.
Results: Eleven eyes of 11 patients were included in our study. The visual acuity improved in 8 eyes and remained unchanged in 3 eyes. The preoperative intraocular pressure (IOP) was significantly decreased at the last follow-up (48.8±4.3 to 17.0±1.5 mm Hg, <0.001). All eyes needed three topical anti-glaucomatous medications before surgery, but the number was significantly reduced to 0.72±0.19 at the last visit (<0.001). Four eyes had choroidal detachment and 3 eyes had minor hyphemia, all of which gradually resolved without treatments in one week.
Conclusion: Ahmed glaucoma valve implantation combined with 23-gauge vitrectomy might be a safe and alternative treatment for NVG with PDR.

Anatomy of Risk: Decoding the Predictors of Vascular Access Complications in Transcatheter Aortic Valve Replacement.
Catheter Cardiovasc Interv

Department of Surgery, University of North Dakota School of Medicine and Health Sciences, Grand Forks, North Dakota, United States.
Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.
Long-Term Impact of Gender Differences After Transcatheter Aortic Valve Implantation.
CJC Open
December 2024
Department of Cardiology, Keio University School of Medicine, Tokyo, Japan.
Background: The short-term and midterm impact of gender differences on transcatheter aortic valve implantation (TAVI) has been studied. However, the impact on long-term clinical outcomes remains unclear. The objective of the study was to investigate the impact of gender differences after TAVI on long-term clinical outcomes and structural valve deterioration (SVD).

Transcatheter caval valve implantation (CAVI) is an emerging treatment option for inoperable patients with severe tricuspid regurgitation (TR). We present a case of a 76-year-old lady with severe TR and recurrent right heart failure who improved after CAVI. This is the first such case in a rare environment.

Background/purpose: Transcatheter aortic valve replacement (TAVR) with ACURATE neo2 showed better hemodynamic outcomes by mitigating paravalvular leakage (PVL) compared with ACURATE neo, and revealed promising one-year outcomes in single-arm studies. However, studies comparing the hemodynamic and clinical outcomes of the two valves are still scarce. Therefore, this study aimed to compare the one-year hemodynamic and clinical outcomes between the neo2 and neo.

Background: Lower mini-sternotomy offers the advantage of providing excellent visualization of the 4 cardiac cavities, allowing surgical treatment of aortic, mitral and tricuspid valves as well as any intra-cavitary procedure. Technical issues, as well as safety and echocardiographic results of this approach, are lacking. The aim of this retrospective study was to describe outcomes of lower mini-sternotomy to treat valvulopathies and other intracardiac surgeries.
