Heart To Heart, Mom To Mom, Karis L. Tekwani

Journal of Patient-Centered Research and Reviews

This essay describes the human connection forged between two young moms, one the physician and one the patient, when their paths collided one night in the emergency department of a busy hospital. It describes a challenging and most memorable care experience in the career of a young emergency physician, the clinical outcome, and the patient’s appreciative follow-up message years later.

Incidental Finding Of Anomalous Pulmonary Venous Return Of The Left Upper Lobe, A Rare Anatomical Variation, Anika Dutta, Loren Zuiderveld

Journal of Patient-Centered Research and Reviews

Partial anomalous pulmonary venous return (PAPVR) is a rare congenital abnormality in which 1 to 3 of the pulmonary veins connect to the right atrium rather than the left atrium. In this synthesis of the literature on PAPVR of the left upper lobe, we attempt to illustrate this clinical entity using a case detected incidentally on chest computed tomography, explain the anatomical aspects of this anomaly, and summarize the reported incidence and etiology of left-sided PAPVR. Lastly, differential diagnoses, clinical relevance, and management of left-sided PAPVR are presented. The identification of this variant is important, as it may have serious …

Covid-19 Deliveries: Maternal Features And Neonatal Outcomes, Viviana Zlochiver, Blair Tilkens, Ana Cristina Perez Moreno, Fatima Aziz, M. Fuad Jan

Journal of Patient-Centered Research and Reviews

Integrated, data-driven criteria are necessary to evaluate delivery outcomes in pregnancies affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the ongoing COVID-19 pandemic. This study analyzed maternal demographics, clinical characteristics, treatments, and delivery outcomes of 85 ethnically diverse, adult pregnant women who tested positive for SARS-CoV-2 at the time of delivery. Median maternal and gestational ages were 27 years (interquartile range [IQR]: 23–31) and 39 weeks (IQR: 37.3–40.0), respectively. Of the 85 SARS-CoV-2–positive participants, 67 (79%) had no COVID-19 symptoms at the time of routine COVID-19 admission testing, 14 (16%) reported mild COVID-19 symptoms, and 4 (5%) presented …

Characterizing Recurrence Following Hybrid Ablation In Patients With Persistent Atrial Fibrillation, David C. Kress, Lynn Erickson, Tadele W. Mengesha, David Krum, Jasbir Sra

Journal of Patient-Centered Research and Reviews

Purpose: It is It is widely accepted that atrial fibrillation (AF) accounts for half of arrhythmia recurrences following endocardial catheter ablation of AF. An epicardial-endocardial approach (hybrid) has emerged as an alternative to endocardial ablation alone for the treatment of AF, yet recurrence after a hybrid procedure has not been well characterized. This retrospective study is aimed at characterizing recurrence following hybrid ablation for patients with persistent AF.

Methods: Patients with persistent AF (N = 108) received both endocardial and epicardial ablation of the posterior left atrial wall using catheter ablation and a small midline surgical approach (hybrid). Presence of …

Myocardial Work Index: A Novel Method For Assessment Of Myocardial Function In South Asian Recreational Athletes, Shantanu Sengupta, Renuka Jain, Nitin Burkule, Susan Olet, Bijoy K. Khandheria

Journal of Patient-Centered Research and Reviews

Purpose: We used a novel noninvasive method based on speckle-tracking echocardiography to evaluate myocardial performance in South Asian recreational athletes who completed a half marathon.

Methods: Transthoracic echocardiography was performed on 24 recreational athletes 48 hours before they took part in a half marathon (premarathon), within 2 hours of half marathon completion (postmarathon), and 72 hours after completion. Clinical, laboratory, and echocardiographic variables were collected. Speckle-tracking echocardiography was performed in all subjects to characterize myocardial mechanics.

Results: Mean age of participants was 41.8 ± 7.4 years, and 23 (95.8%) were male. No subject had a prior history of coronary artery …

Variations In Practice Of Apnea Test For Brain Death: Review From A Multihospital Health Care System, Jeffrey Stein, Marvi V. Rijhwani, Ernesto Brauer

Journal of Patient-Centered Research and Reviews

Background: Ventilation encompasses both active and passive processes. Air is initially drawn into the lungs due to a negative intrathoracic pressure created using the respiratory muscles, most importantly the diaphragm. In contrast, expiration is the passive relaxation of the respiratory muscles. Oxygenation occurs when oxygen diffuses across the alveolar-capillary membrane. The ability to oxygenate without ventilation has been termed apneic diffusion oxygenation or apneic oxygenation. We believe it is crucial to keep alveoli open in order for adequate oxygenation to occur. This can be achieved with the aid of positive end-expiratory pressure (PEEP). We investigated this concept in patients who …

Relative Associations Of Age, Height, And Weight On Sinus Of Valsalva And Mid-Ascending Aorta: An Imaging And Epidemiology Study, Mirza Nubair Ahmad, Syed Haris Pir, Mirza Mujadil Ahmad, Sharmeen Hussaini, Bijoy K. Khandheria, A. Jamil Tajik, Khawaja Afzal Ammar

Journal of Patient-Centered Research and Reviews

Background: Prior studies show ascending aorta diameter varies with age, height and weight, but they did not evaluate relative influence of these variables on aortic diameter. Since height is genetically determined, and genetic disorders like Marfan syndrome are predominantly associated with sinus of Valsalva (SOV) dilation, we hypothesized height may have stronger association with SOV.

Purpose: Based on anecdotal observation, since age, weight and obesity are acquired attributes, we hypothesized age, weight and body mass index may have greater association with mid-ascending aorta (MAA) diameter, even in normal patients.

Methods: We evaluated echocardiographic studies of patients ≥ 15 years old …

Seniors Welcome! Avoiding The Trap Of Age Limits In Health Research, Arshad Jahangir

Journal of Patient-Centered Research and Reviews

The guest editor introduces this specialty issue of the Journal of Patient-Centered Research and Reviews, which focuses on cardiovascular diseases in the elderly. The reality of an aging population has increased the need for better evidence-based medicine in older patients. However, randomized controlled trials frequently exclude such patients, especially those with comorbidities, from study. This practice ignores the fact that physiologic changes to the cardiovascular system caused by the aging process and aging-associated diseases create clinical dilemmas distinct from those in younger patients. Considering the rising costs of health care and growing incidence of cardiovascular disease, research efforts and …
