Definition Of The 3d Position And Motion Status Of The Moving Heart Based On 2d Projections, Lawrence D. Orijuela

Electronic Theses, Projects, and Dissertations

This thesis presents a novel application of deep learning to the estimation of pulmonary vein coordinates using X-ray image pairs from a FORBILD Thorax phantom derived motion dataset. A Siamese neural network was developed to predict the 3D coordinates of one pulmonary vein at a time, specifically the Right Superior Pulmonary Vein (RSPV), Left Superior Pulmonary Vein (LSPV), Left Inferior Pulmonary Vein (LIPV), or Right Inferior Pulmonary Vein (RIPV), based on two-dimensional projection images.

The input data consisted of over 1.6 million grayscale X-ray image pairs across 1331 virtual patients, each annotated with ground truth 3D coordinates. To manage memory …

Comparative Value Of Echocardiography Vs. Right Heart Catheterization In Heart Failure With Preserved Ejection Fraction, Nathanael Tran, Mohammad Shaar, Hussein Al-Sudani, Ramy Sedhom, Hamza Akhtar, Kevin Bryan Lo, Gregg S. Pressman

Einstein Health Papers

BACKGROUND: Echocardiography and right heart catheterization (RHC) are useful in the evaluation of heart failure with preserved ejection fraction (HFpEF). We compared the two among decompensated HFpEF patients to determine their relative value in predicting all-cause mortality and a composite of cardiovascular (CV) death and heart failure (HF) readmission at 1 year.

METHODS: One hundred seventy-eight decompensated HFpEF patients who underwent both procedures and survived to hospital discharge were retrospectively identified. Hospital records and the National Death Index were queried to determine outcomes. Echocardiographic and invasive parameters were tested for significant associations with each outcome. Additionally, three predictive models were …

A Human Factors Analysis And Classification System (Hfacs) Approach To Compare Cardiovascular, Orthopedics, Trauma Care, And Neurosurgery, Asfandyar Khan

Doctoral Dissertations and Master's Theses

Background: Despite significant progress in patient safety, human error continues to occur at high rates in procedural settings. Traditional safety models tend to focus on retrospective incident analysis, often overlooking the systemic conditions that allow errors to occur. The Human Factors Analysis and Classification System (HFACS) offers a proactive lens to understand how and where errors emerge and is useful for identifying active and latent failures.

Objective: To evaluate the utility and reliability of the Human Factors Analysis and Classification System (HFACS) in categorizing and comparing the pattern of frequencies (events) in cardiovascular, orthopedic, trauma care, and neurosurgical procedure.

Interplay Of Menopause, Coronary Artery Calcium Score And Cardiovascular Disease Risk, Tanisha Mishra, Diksha Sanjana Pasnoor, Murtaza Gandhi, Nida Mohamed, Shaylika Chauhan, Kokou Adompreh-Fia, Kesha Mayank Doshi, Prerana Sevella, Rupak Desai

Abington Jefferson Health Papers

BACKGROUND: Postmenopausal women face an increased risk of cardiovascular disease (CVD) due to estrogen withdrawal, which exacerbates traditional cardiovascular risk factors such as dyslipidemia, glucose intolerance, and hypertension. Coronary Artery Calcium Score (CACS), a well-established marker of subclinical atherosclerosis, has emerged as a key predictor of adverse cardiovascular events. Despite the recognized association between menopause and heightened CVD risk, there remains a paucity of literature exploring the specific role of menopause in influencing CACS and its implications for cardiovascular morbidity and mortality.

AIM: To examine the interplay between menopause, CACS, and cardiovascular health by synthesizing existing literature.

METHODS: A comprehensive …

Experience with the Aurora extravascular (EV) implantable cardioverter-defibrillator (ICD) (Medtronic, Minneapolis, MN, USA) remains limited among pediatric centers in contrast to its broader implantation in adults. We evaluated our single-center experience with the EV ICD as part of our standard ICD options for treatment of malignant ventricular arrhythmias in pediatric subjects. Following approval for EV ICD implantation at our center, five consecutive adolescent patients underwent implantation over a 7-month period. Patient characteristics, qualification for EV ICD placement, nuances in EV ICD implantation in each patient, and post-implant follow-up were reviewed. A total of six out of eight consecutive ICD candidates …

In-Silico Assessment Of Aortic Valve Function And Mechanics Under Hypertension, Jason A. Shar, Philippe Sucosky

Faculty Articles

Introduction: Calcific aortic valve disease (CAVD) is the most common heart valve disorder. While hypertension is a major risk factor, the mechanisms by which elevated blood pressure contributes to calcification are largely unknown. Given the established sensitivity of aortic valve (AV) tissue to mechanical cues, hypertension may subject AV leaflets to a stress state conducive to CAVD. To address this hypothesis, the objective of this study was to compare AV function and mechanics under normotensive (NTN, 120/ 80 mmHg), pre-hypertensive (preHTN, 125/80 mmHg) and hypertensive (HTN, 130/90 mmHg) conditions using fluid-structure interaction modeling.

Methods: AV flow and leaflet dynamics were …

From Chest Pain To Recovery: A Rare Case Of Anomalous Origin Of The Circumflex Artery From The Pulmonary Artery In A Child And The Role Of Timely Surgical Intervention, A.V. Kauk, Serezha Manukian, A.N. Arkhipov, A.V. Voitov, I.A. Soynov

Journal of the Saudi Heart Association

This report highlights the diagnostic challenges and successful surgical management in a symptomatic pediatric case with anomalous origin of the circumflex artery from the pulmonary artery. A 4-year-old boy presented emergently with dyspnea and substernal pain. Coronary angiography identified the circumflex artery originating anomalously from the right pulmonary artery. Emergency surgical reimplantation to the aorta was performed, with subsequent normalization of cardiac function (EF 67% at 3-month follow-up). Although exceptionally rare, anomalous origin of the circumflex artery from the pulmonary artery requires high clinical suspicion in pediatric patients with ischemic symptoms. Early anatomical correction yields excellent outcomes, as demonstrated in …

Development of a Longitudinal, Small-Group POCUS Curriculum for Internal Medicine Residents

Introduction

Point-of-Care Ultrasound (POCUS) is integral for clinicians to enhance their diagnostic and procedural skills. Unlike Emergency Medicine or Anesthesia training programs, Internal Medicine programs often lack a structured and standardized curriculum. We thus developed a longitudinal and multi-pronged POCUS curriculum aimed at building trainee competency when utilizing ultrasound for diagnostic and procedural work-up.

Methods

The curriculum encompasses the following: basics of ultrasound, ultrasound-guided procedures, thoracic ultrasound/Bed Lung Ultrasound in Emergency (BLUE), and cardiac ultrasound/Focus-Assessed Transthoracic Echocardiography (FATE). These modules were integrated into the residents’ clinic blocks. We utilized …

Focal Constrictive Pericarditis, An Unusual Cause For Biventricular Failure, Farhan Parachikkottil, Harikishore U, Shijoy P, Sajeer Kalathingathodika, Krishnakumar Prabhakaran, Kader Muneer

Journal of the Saudi Heart Association

A 34 year old male who had undergone surgical closure of a ventricular septal defect at the age of 4 years, after a long asymptomatic period, presented with heart failure and was diagnosed with atrial flutter and biventricular dysfunction. Chest X-ray showed a band-like calcification in the atrioventricular groove. Echocardiography revealed dilated atria, focal calcification with constriction at the atrioventricular groove, and biventricular systolic dysfunction. Focal constrictive pericarditis occurring in post-cardiac surgery patients is very rare. Here we report a case of focal variant of constrictive pericarditis manifesting in a young male after 3 decades of ventricular septal defect repair.

BACKGROUND: Same-day discharge (SDD) after percutaneous coronary intervention (PCI) may be altered when complications occur. We sought to determine whether risk of the most common complication, acute kidney injury (AKI), is associated with SDD in practice.

METHODS: Using the NCDR (National Cardiovascular Data Registry) CathPCI registry, we calculated the AKI risk for elective PCIs from 2018 to 2022 using the NCDR prediction model. Hierarchical logistic regression models were constructed to predict SDD with AKI risk and procedural variables as fixed effects, and site as a random effect. Trends in SDD rate across AKI risk categories were described and variability across …
