Purpose: Valsalva hemorrhagic retinopathy is characterized by retinal hemorrhages that develop after a Valsalva maneuver that consists of a forcible exhalation against a closed glottis, thereby creating a sudden increase in the intrathoracic or intraabdominal pressure. We present a patient who developed retinal and vitreous hemorrhages with multiple retinal nonperfused areas after extreme physical training with shouting on a mountainous area. This exercise was part of his training as a member of a Japanese traditional cheerleading team.

Method: Case presentation.

Results: A 19-year-old man developed an acute decrease in the vision to 0.3 in his left eye after running on hilly roads at approximately 800 m while shouting fight songs for several hours. Ophthalmoscopy showed a fresh vitreous hemorrhage that covered the entire macula and was connected to the optic disk in the left eye. The vitreous hemorrhage spontaneously resolved and an intraretinal hemorrhage and nonperfused area emerged. His visual acuity returned to 1.2.

Conclusion: Prolonged, strenuous physical exertion with shouting during training exercises can lead to Valsalva hemorrhagic retinopathy. Several other factors, such as hot weather, altitude, and dehydration, may have played an additive role in increasing the venous pressure and hypoxia in the retinal vessels, which then caused the retinopathy.

Multifaceted approach to evacuating multi-level premacular hemorrhage in a case of suspected Valsalva retinopathy - a case report.

BMC Ophthalmol

Department of Retina and Vitreous, Narayana Nethralaya, #121/C, 1st R Block, Chord Road, Rajaji Nagar, Bengaluru, Karnataka, 560010, India.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.

Methods: This is a retrospective interventional case report.

Purpose: There are limited reports on the potential link between Lp(a) and ARDM. Thus, we examined the relationship between Lp(a) and ARDM among hypertensive patients.

Methods: We used echocardiography to measure ARDM in 513 consecutively hospitalized patients.

Clinical Correlates of Efficacy of Pyridostigmine in the Treatment of Orthostatic Hypotension.

Hypertension

December 2024

Vanderbilt Autonomic Dysfunction Center, Division of Clinical Pharmacology, Vanderbilt University Medical Center, Nashville, TN. (L.E.O., A.D., C.A.S., A.G., B.K.B., S.P., I.B.).

Background: The cholinesterase inhibitor pyridostigmine is used to treat orthostatic hypotension by facilitating cholinergic neurotransmission in autonomic ganglia, thereby harnessing residual sympathetic tone to increase blood pressure (BP) preferentially in the upright posture. We hypothesized that less severe autonomic impairment was associated with greater pressor responses to pyridostigmine.

Methods: To identify predictors of pressor response, linear regression analyses between the effect of pyridostigmine on upright BP and markers of autonomic impairment were retrospectively conducted on 38 patients who had a medication trial with pyridostigmine (60 mg single dose).

Native Valve and Native Neo-Sinus Remodeling Following Transcatheter Aortic Valve Replacement.

Circ Cardiovasc Interv

December 2024

Cardiovascular Translational Laboratory, Providence Research and Centre for Heart Lung Innovation, Vancouver, British Columbia, Canada (J.Y., H.G., J.J., A.L., J.G.W., J.S., D.M., S.L.S.).

Background: Transcatheter aortic valve replacement (TAVR) pushes aside the diseased native aortic valve and creates a native neo-sinus bordered by the aortic root wall and the displaced native valve. There are limited data on the progression of native valve disease post-TAVR and no previous analysis of the native neo-sinus.

Methods: Native aortic valves and native neo-sinus explants obtained post-TAVR were evaluated histologically (hematoxylin and eosin, Movat pentachrome, and Martius Scarlet Blue stains) and by immunohistochemistry (TGF-β1 [transforming growth factor-beta 1], FAP [fibroblast activation protein], and ALP [alkaline phosphatase]) to assess disease mechanisms.
