Pragmatic assessment of resident performed cardiac point of care ultrasound using a validated scoring metric.

Background: Cardiac point of care ultrasound (POCUS) is increasingly utilized by trainees across various specialties and can rapidly assess the cardiac status of unstable patients. However, the quality of trainee performed cardiac examinations has been reported only in controlled studies. In this study we aimed to assess the quality of all cardiac POCUS performed by internal medicine trainees at a major academic medical center over a three-year period. Methods: 256 studies were included and were graded by experts blinded to postgraduate year (PGY) using a previously validated scoring metric. Results: We found significant improvement in overall quality of resident performed cardiac POCUS from PGY 1 to 3 (10.8, 10.2, 13.2, p = 0.012). Assessment of left ventricular function was possible in 82% of studies and increased from PGY 1 to PGY 3 (77%, 76%, 88%, p = 0.025). Similar trends were seen in the assessment of the pericardial space (67%, 71%, 84%, p = 0.012). Images sufficient for right ventricular and volume status assessment were less commonly found (65%, 60%, 75% and 60%, 49%, 57%, respectively). Conclusions: This study provides a real world experience of the level of diagnostic accuracy that can be expected from IM trainees with minimal hands-on supervision.

Coexisting Coronary and Carotid Artery Disease - Which Technique and in Which Order? Case Report and Review of Literature.

Coexisting carotid artery stenosis and coronary artery disease is common and there is currently no consensus in treatment guidelines on the timing, sequence and methods of revascularization. We report a case of a patient with symptomatic triple vessel coronary artery disease as well as asymptomatic severe right internal carotid artery stenosis. Our patient underwent myocardial revascularization first, because she presented with unstable angina and was asymptomatic neurologically. This article summarizes current literature about the approach to carotid and coronary artery revascularization and addresses the decision-making process regarding the timing and sequence of revascularization.

Apixaban as a Rare Cause of Leukocytoclastic Vasculitis.

Apixaban is a rare cause of leukocytoclastic vasculitis (LCV). To our knowledge, there is only one other reported case due to apixaban in the literature. We present a case of apixaban-induced leukocytoclastic vasculitis in a 95-year-old male. He had been started on apixaban 12 days prior to presentation and developed worsening palpable purpura of his lower extremities. Possible etiologies of this new rash were excluded, with biopsy showing extensive purpura with superficial perivascular neutrophilic infiltrate and leukocytoclasis. Apixaban was discontinued, and the patient was started on a slow prednisone taper with subsequent resolution of his rash.

TAVR: A Review of Current Practices and Considerations in Low-Risk Patients.

Transcatheter aortic valve replacement (TAVR) is an established treatment for severe, symptomatic, aortic stenosis (AS) in patients of all risk categories and now comprises 12.5% of all aortic valve replacements. TAVR is a less invasive alternative to traditional surgical aortic valve replacement (SAVR), with equivalent or superior outcomes. The use of TAVR has increased rapidly. The success and increase in use of TAVR are a result of advances in technology, greater operator experience, and improved outcomes. Indications have recently expanded to include patients considered to be at low risk for SAVR. While TAVR outcomes have improved, remaining challenges include the management of coexistent coronary artery disease, prevention of periprocedural stroke, and issue of durability. These issues are even more relevant for low-risk, younger patients.
