    Abstract Leadless pacemaker systems (LPs) were developed as an alternative to traditional transvenous permanent pacemakers (TV-PPM) due to increasing rates of device and procedural related complications, leading to a high-cost burden to our health-care system. LPs were initially indicated for single-chamber ventricular pacing; however, recent developments have allowed for dual-chamber pacing too. These systems have demonstrated highly successful implant rates with stable pacing performance. This article describes the retrieval techniques of the Micra LPs and ways to mitigate challenges encountered during the retrieval process.

  2. Article ; Online: A New Tool for Holistic Residency Application Review: Using Natural Language Processing of Applicant Experiences to Predict Interview Invitation.

    Abstract Problem: Reviewing residency application narrative components is time intensive and has contributed to nearly half of applications not receiving holistic review. The authors developed a natural language processing (NLP)-based tool to automate review of applicants' narrative experience entries and predict interview invitation.
    Approach: Experience entries (n = 188,500) were extracted from 6,403 residency applications across 3 application cycles (2017-2019) at 1 internal medicine program, combined at the applicant level, and paired with the interview invitation decision (n = 1,224 invitations). NLP identified important words (or word pairs) with term frequency-inverse document frequency, which were used to predict interview invitation using logistic regression with L1 regularization. Terms remaining in the model were analyzed thematically. Logistic regression models were also built using structured application data and a combination of NLP and structured data. Model performance was evaluated on never-before-seen data using area under the receiver operating characteristic and precision-recall curves (AUROC, AUPRC).
    Outcomes: The NLP model had an AUROC of 0.80 (vs chance decision of 0.50) and AUPRC of 0.49 (vs chance decision of 0.19), showing moderate predictive strength. Phrases indicating active leadership, research, or work in social justice and health disparities were associated with interview invitation. The model's detection of these key selection factors demonstrated face validity. Adding structured data to the model significantly improved prediction (AUROC 0.92, AUPRC 0.73), as expected given reliance on such metrics for interview invitation.
    Next steps: This model represents a first step in using NLP-based artificial intelligence tools to promote holistic residency application review. The authors are assessing the practical utility of using this model to identify applicants screened out using traditional metrics. Generalizability must be determined through model retraining and evaluation at other programs. Work is ongoing to thwart model "gaming," improve prediction, and remove unwanted biases introduced during model training.

    Abstract We discuss a case of a 42-year-old female who was admitted for chronic intractable lower back pain requiring elective spinal surgery. Postoperatively, she experienced chest pressure and abdominal pain with a notable elevation in cardiac markers. A cardiac catheterization and left ventriculogram revealed normal coronary arteries and basal anterolateral hypokinesis, with the normal movement of the distal segment of the anterior wall. A rare variant of stress cardiomyopathy was diagnosed.

    Abstract A 68-year-old African American male presented to the emergency department with back and abdominal pain. Imaging showed a posterior mediastinal mass interposed between the carina, the left main stem bronchus, and the descending thoracic aorta. Biopsy of the mass favored a metastatic prostate carcinoma, which is an extremely rare presentation.

    Abstract The term paroxysmal supraventricular tachycardia encompasses a heterogeneous group of arrhythmias with different electrophysiologic characteristics. Knowledge of the mechanism of each supraventricular tachycardia is important in determining management in the office, at the bedside, and in the electrophysiology laboratory. Paroxysmal supraventricular tachycardias have an abrupt onset and offset, typically initiating and terminating with premature atrial ectopic beats. In the acute setting, both vagal maneuvers and pharmacologic therapy can be effective in arrhythmia termination. Catheter ablation has revolutionized therapy for many supraventricular tachycardias, and newer techniques have significantly improved ablation efficacy and decreased periprocedural complications and procedure times.

    Abstract A spontaneous occurrence of cholesterol embolization syndrome causing small bowel obstruction and perforation is a highly scarce event. In this article, we report a case of spontaneous cholesterol embolism resulting in small bowel obstruction and perforation in a 52-year-old male with multiple cardiovascular and medical comorbidities. In our patient, the source was an eccentric left lateral atherosclerotic plaque from the abdominal aorta that was identified using computed tomography. A distal occlusion in numerous small intestinal arteries due to cholesterol embolism was confirmed on biopsy after surgical resection. (

    Abstract Background: Bystander cardiopulmonary resuscitation (CPR) is the cornerstone in managing out-of-hospital cardiac arrest (OHCA). However, India lacks a formal sudden cardiac arrest (SCA) registry and the infrastructure for a robust emergency medical services (EMS) response system. Also, there exists an opportunity to improve widespread health literacy and awareness regarding SCA. Other confounding variables, including religious, societal, and cultural sentiments hindering timely intervention, need to be considered for better SCA outcomes.
    Objectives: We highlight the current trends and practices of managing OHCA in India and lay the groundwork for improving the awareness, education, and infrastructure regarding the management of SCA.
    Conclusion: Effective management of OHCA in India needs collaborative grassroots reformation. Establishing a large-scale SCA registry and creating official and societal guidelines will be pivotal for transforming OHCA patient outcomes.

    Abstract As per the Centers for Disease Control and Prevention (CDC), the incidence of myocardial infarction (MI) is reported to be 805,000 cases annually in the United States (US). Although commonly occurring in elderly individuals with underlying cardiovascular comorbidities or younger generations with familial predispositions serving as risk factors, it is extremely rare for an isolated event to occur in teenagers with a history of marijuana use. In this article, we report a rare case of ST-elevation myocardial infarction (STEMI) in a 19-year-old male with no past medical history that was attributed to marijuana use. This case report and review of literature depict a potential association between marijuana use and STEMI. We also highlight potential clinical implications to aid healthcare professionals in making an early diagnosis and achieving a timely management strategy.
