ABSTRACT
Objective: The objective of this study is to explore the role of adjunctive percutaneous revascularization of the hand in the management of patients with systemic sclerosis-associated refractory digital ischemia. Methods: We present our initial experience of using percutaneous upper extremity interventions to treat patients with systemic sclerosis and symptomatic Raynaud's phenomenon who presented with either refractory digital ischemia or non-healing ulcers. We discuss patient characteristics, procedural findings, and short-term clinical outcomes of these interventions. Results: We performed 14 interventions in 6 patients with non-healing digital ulcers or refractory ischemia secondary to systemic sclerosis. Angioplasty was performed at or below the wrist in conjunction with intravenous prostaglandin therapy, started prior to or immediately after the revascularization procedure. All patients experienced symptomatic relief and demonstrated accelerated wound healing. Two patients required an additional procedure to treat recurrent ischemia (without new ulceration) in the treated digit. Three of the patients underwent multiple procedures during the study period to treat new ischemic lesions or Raynaud's phenomenon symptoms, highlighting the progressive nature of the vascular occlusions in systemic sclerosis. There were no adverse events related to the interventions. Conclusions: Our retrospective analysis suggests that percutaneous revascularization in combination with vasodilator therapy in systemic sclerosis-associated digital ischemia is safe and can facilitate the healing of long-standing ulcers. Its role in the management of refractory digital ischemia in patients with systemic sclerosis should be explored further.
ABSTRACT
We present the case of a young woman with systemic sclerosis (SSc) and refractory digital ulceration who was successfully treated with percutaneous revascularization of chronically occluded ulnar and radial arteries. To our knowledge, this is the first detailed report of limb salvage in SSc-induced hand ischemia in which contemporary endovascular techniques were used. (Level of Difficulty: Advanced.).
ABSTRACT
Left ventricular (LV) thrombus is a potentially serious complication affecting males and females with ischemic and nonischemic cardiomyopathy-specifically, after acute myocardial infarctions of the anterior left ventricular wall and long-standing tachyarrhythmias, respectively. LV thrombi pose significant risks for systemic embolization and devastating stroke events, while also demanding a treatment carrying inherent risks of its own. It is therefore imperative to have accurate detection of these ventricular thrombi and an appropriate understanding of the risks and benefits regarding management. Anticoagulation using warfarin has long been established as the gold-standard level of care in the current guidelines of the American College of Cardiology but the advent of direct oral anticoagulants (DOACs) prompts a re-examination of the literature. The particular question we seek to answer lies in the efficacy of these drugs and the safety and outcomes when used to treat LV thrombi. Recent case reports, meta-analyses, and most recently, the breakthrough of 2 novel randomized controlled trials have shown DOACs to be a promising treatment for LV thrombus. Contrarily, some retrospective cohort reviews suggest less-than-promising outcomes. This meta-analysis hopes to provide a current, curated review of up-to-date safety and efficacy in the documented tales of DOACs and LV thrombi that has been published since early 2020-by selecting these curated case studies, and analyzing the most recent randomized controlled trials, we hope to engage the reader with clearer illustrations of the key components of both the advocacy and warning of this pharmaceutical intervention.

Background: Carcinoid heart disease (CnHD) is a frequent cause of morbidity and mortality in patients with neuroendocrine tumors and carcinoid syndrome. Although valve replacement surgery appears to decrease all-cause mortality in patients with advanced CnHD, few studies have investigated the outcomes of patients after valve replacement. Methods: We conducted a multi-institution retrospective registry of patients who received both tricuspid and pulmonic bioprosthetic valve (TV/PV) replacements for advanced CnHD from November 2005 to March 2021. Patients were followed post-operatively with echocardiographic studies every 3 months. Carcinoid valvular heart disease scores were used to monitor valve degeneration. Neuroendocrine tumor treatment, their administration times, and associations with echocardiographic findings were recorded. Results: Of 87 patients with CnHD, 22 patients underwent simultaneous surgical TV and PV replacement. In 6 patients (27.3%), increased PV Vmax was the first echocardiographic manifestation of valve degeneration in the setting of occult neurohormonal release. Post-operative telotristat ethyl and peptide receptor radionuclide therapy appeared to stabilize PV Vmax. The PV Vmax showed consistent elevation in the entire patient population when compared to baseline, while bioprosthetic TV echocardiographic parameters were relatively unchanged throughout. Post-operative warfarin therapy did not affect the rate of PV degeneration, and no major bleeding was recorded during or after post-operative anticoagulation therapy. Conclusion: Bioprosthetic valve degeneration is common in CnHD. Monitoring with echocardiographic studies every 3 months, focusing on PV velocities, could identify patients with occult disease that very likely promotes valve degeneration. Novel neuroendocrine tumor therapies may have a beneficial impact on valve degeneration.
