Optimal Bag Valve Mask Ventilation Efficacy Of Smart Bag Ventilation Compared To Traditional Adult And Paediatric Bag Valve Ventilation During Cardiopulmonary Resuscitation, Ian Dawson

Theses: Doctorates and Masters

Background: Out-of-Hospital Cardiac Arrest (OHCA) is one of the world’s leading causes of mortality. Survival rates are low, ranging from 3.1–20.4% internationally. The most effective oxygenation method for patients during pre-hospital cardiac arrest is ventilating using a self- inflating Bag-Valve-Mask (BVM). Yet, extensive research has identified a lack of compliance with ventilator guidelines during OHCA cardiopulmonary resuscitation (CPR). As a result, clinicians often ventilate patients too aggressively using the BVM, delivering breaths excessively higher than the International Liaison Committee on Resuscitation (ILCOR) recommended rate of 10 breaths per minute (BPM). Hyperventilation can lead to complications such as aspiration, barotrauma, and …

Pumping Iron, Straining Hearts: Androgen Building Cardiomyopathy In A Middle Aged Bodybuilding Enthusiast, Milan Terzic, Yash B. Patel

Graduate Medical Education Research Journal

A 46-year-old bodybuilder presenting with new onset dyspnea found to have a new onset non-ischemic cardiomyopathy (CM) attributed to exogenous trenbolone and testosterone use. Steroid cessation and guideline-directed heart failure therapy led to notable recovery in left ventricular function supported by global longitudinal strain, ejection fraction and symptomatology.

Anabolic steroid-induced CM involves multiple mechanisms including lipid disturbances, hypertrophy, reduced receptor sensitivity, and cell damage. This case emphasizes the importance of recognizing anabolic steroid misuse as a potential cause of non-ischemic cardiomyopathy in middle aged men. With prompt discontinuation of steroids, remained abstinence and early initiation of guideline-directed medical therapy, myocardial …

Faculty, Staff and Student Publications

Aims: Chronic primary mitral regurgitation (MR) results in progressive left ventricular (LV) remodelling. Abnormal myocardial deformation (strain) can be present despite preserved ejection fraction (EF). Cardiovascular magnetic resonance (CMR) feature-tracking techniques allow assessment of global longitudinal strain (GLS) from routine cine images. The aim of this study is to evaluate the prognostic value of CMR feature tracking-derived GLS in patients with primary MR.

Methods and results: Consecutive patients undergoing CMR for chronic MR from January 2012 to June 2018 were enrolled. Patients with LVEF < 50% were excluded. The composite primary outcome aiming to detect decompensation related to MR comprised (i) referral for mitral surgery owing to symptoms or LV systolic dysfunction or (ii) cardiovascular death. The secondary outcome was all-cause death. A total of 422 patients were followed for a median of 2.7 years, and the primary endpoint was met in 93 patients (34 patients reported symptoms at baseline). At multivariable analysis, GLS≥ -16.6% was associated with primary outcome [hazard ratio (HR) 1.90, P = 0.01]. In moderate MR cohort, patients with GLS≥ -16.6% had worse event-free survival, whereas there was no significant difference in mild or severe MR groups. GLS≥ -16.0% remained associated with all-cause death after adjusting for other covariates including the MR severity (HR 2.24, P = 0.02).

Conclusion: In patients with primary MR with preserved systolic function, GLS was associated with our composite …

Potential Of Right Ventricular Function Assessment With Echocardiography In Transcatheter Aortic Valve Replacement, Yoshihisa Morita, Taro Kariya, Michael Dougherty, Andrew Peters, Nicholas Ruggiero

Division of Cardiology Faculty Papers

BACKGROUND: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment. In this study, we compared RV function echocardiographic assessment methodologies in TAVR and investigated its clinical utility.

METHODS: This was a prospective, observational study of TAVR at a large academic hospital. Inclusion criteria were adult patients undergoing TAVR requiring intraoperative …

Faculty, Staff and Students Publications

OBJECTIVES: A prolonged cardiopulmonary bypass (CPB) time of over 180 min is linked to poorer outcomes and higher mortality in cardiac surgery. This study examines how glypican-1 shedding, matrix metallopeptidase 9 (MMP9), and the pro-inflammatory cytokine IL-1β may contribute to endothelial dysfunction in patients undergoing on-pump surgery with an extended CPB.

METHODS: Fifty-one patients undergoing cardiac surgical procedures were divided into two groups based on the intraoperative CPB duration: (i) normal CPB (<180 >min,

RESULTS: Before surgery, the plasma levels of glypican-1, MMP9, and IL-1β were comparable between the normal CPB and the prolonged CPB groups. However, after the end …

Redo Minimally Invasive Right Atrial Mass Removal After Surgical Atrial Septal Defect Closure, Chirag Doshi, Pratyaksha Rana, Vidur Bansal, Megha M Sheth, Dinesh Patel

Journal of the Saudi Heart Association

Atrial septal defects are among the most prevalent congenital anomalies necessitating surgical intervention. Thrombus formation is a recognized complication that is typically characterized by an embolic event following patch-based repair. However, thromboembolic complications following primary repair of atrial septal defects are exceedingly uncommon.

Minimally invasive surgery is a suitable alternative to redo sternotomy. We present a 46-year-old man who was diagnosed with a right atrial mass eight years following the patch repair of an atrial septal defect and underwent a successful minimally invasive redo surgery.

Artificial Intelligence In Fetal And Pediatric Echocardiography, Alan Wang, Tam T Doan, Charitha Reddy, Pei-Ni Jone

Faculty, Staff and Students Publications

Echocardiography is the main modality in diagnosing acquired and congenital heart disease (CHD) in fetal and pediatric patients. However, operator variability, complex image interpretation, and lack of experienced sonographers and cardiologists in certain regions are the main limitations existing in fetal and pediatric echocardiography. Advances in artificial intelligence (AI), including machine learning (ML) and deep learning (DL), offer significant potential to overcome these challenges by automating image acquisition, image segmentation, CHD detection, and measurements. Despite these promising advancements, challenges such as small number of datasets, algorithm transparency, physician comfort with AI, and accessibility must be addressed to fully integrate AI …

Prenatal Identification Of Intracardiac Mass Expedites Surgical Management Of Capillary-Venous Malformation, Derek M Norton, Mounica Y Rao, Jianhong Zhang, M John Hicks, Anitha Parthiban, S Kristen Sexson Tejtel

Faculty, Staff and Students Publications

Fetal and neonatal cardiac tumors are rare and often benign. Clinical presentation is primarily related to mass effect, pericardial effusion or arrhythmia. Prenatal detection can assist with risk assessment and inform optimal delivery plan and postnatal management. We report a fetus with a right atrial mass discovered in the third trimester. After successful surgical resection, pathology confirmed the mass to be a capillary-venous malformation, which are rare and challenging to diagnose. The true incidence of these vascular malformations within cardiac spaces is difficult to discern given the historic classification of numerous different vascular malformations under the umbrella term hemangioma.
