Cardiac Metastasis After Curative Treatment Of Hepatocellular Carcinoma: Risk Factors, Treatment Options, And Prognosis, Gaurav Jain, Mathew Otto, Mubeen Khan Mohammed Abdul, Manpreet Chadha, Ajay Sahajpal

Journal of Patient-Centered Research and Reviews

Hepatocellular carcinoma (HCC) is primary hepatic malignancy with a high incidence of recurrence. The risk of recurrence directly correlates to patient’s overall prognosis. Management of advanced HCC involves a combination of surgical resection, locoregional therapy, and systemic treatment. Distant metastases are rare, and intraventricular cardiac metastases are even more infrequent. This brief review details an illustrative case of cardiac metastasis after curative treatment of primary HCC and then summarizes the literature on risk factors, treatment options, and patient prognosis in the setting of distant metastases from HCC. Prognosis of metastasis to the heart is generally poor, and available evidence emphasizes …


Is Home Blood Pressure Monitoring Effective At Controlling Hypertension In African American Patients? A Clin-Iq, Rebecca Nye, Wilhelm Lehmann, Deborah Simpson Jul 2022

Is Home Blood Pressure Monitoring Effective At Controlling Hypertension In African American Patients? A Clin-Iq, Rebecca Nye, Wilhelm Lehmann, Deborah Simpson

Journal of Patient-Centered Research and Reviews

African Americans are disproportionately affected by hypertension, a modifiable contributor to multiple chronic diseases and premature death. Primary care physicians play an important role in hypertension control. Home blood pressure monitoring (HBPM) is an evidence-based method for confirming diagnosis and monitoring hypertension over time. Some studies have found that HBPM may lead to clinically relevant reductions in blood pressure when combined with additional interventions, but few studies have focused specifically on African American populations. Evidence of effectiveness could increase clinical recommendation of HBPM. This clinical inquiry examined whether HBPM improves blood pressure control in African Americans with uncontrolled hypertension. Reviewed …

Background: Cardiovascular health (CVH) from young adulthood is strongly associated with an individual's future risk of cardiovascular disease (CVD) and total mortality. Defining epigenomic biomarkers of lifelong CVH exposure and understanding their roles in CVD development may help develop preventive and therapeutic strategies for CVD.

Methods: In 1085 CARDIA study (Coronary Artery Risk Development in Young Adults) participants, we defined a clinical cumulative CVH score that combines body mass index, blood pressure, total cholesterol, and fasting glucose measured longitudinally from young adulthood through middle age over 20 years (mean age, 25-45). Blood DNA methylation at >840 000 methylation markers was …


Pulsatility Is A Predictive Marker Of Improved Cardiac Function In Patients With Liquid Matrix-Treated Left Ventricular Assist Devices, Philemon Mikail, Rinku Skaria, Marvin Slepian, Janny Garcia, Richard Smith, Zain Khalpey Jul 2022

Pulsatility Is A Predictive Marker Of Improved Cardiac Function In Patients With Liquid Matrix-Treated Left Ventricular Assist Devices, Philemon Mikail, Rinku Skaria, Marvin Slepian, Janny Garcia, Richard Smith, Zain Khalpey

The VAD Journal

Objective: Left ventricular assist devices (LVADs) are utilized as a bridge to transplant or as destination therapy for patients with end-stage heart failure. Although cardiac offloading from these devices rarely leads to complete remodeling and functional recovery, the use of mesenchymal cells to modulate heart failure has been explored in recent years due to its intrinsic regenerative properties. Current methods of evaluating cardiac function have too much variability, difficulty of access, or require too frequent follow up to create universal weaning protocols. We hypothesized that the administration of amniotic allograft liquid matrix (LM) containing amnion-derived mesenchymal stem cells (aMSCs) in …

Case Report On Peri-Operative Surgical And Anaesthetic Management Of Ruptured Humongous Lung Abscess, Khalid Maudood Siddiqui, Akbar Azizullah, Muhammad Saad Yousuf

Department of Anaesthesia

Introduction: Early thoracic empyema is usually treated through video-assisted thoracoscopic (VATS) decortication. Patient selection is important for decortication if an effective surgical outcome is required. Lung isolation techniques are required to provide anesthesia for these patients to facilitate the surgeon while operating on the affected lung. The ultimate target is to protect the non-diseased contra-lateral lung from contamination.
Presentation of case: We are presenting a unique case of 20-year-old female, resident of Karachi, who was brought to the emergency room (ER) with signs of sepsis, hypotension, and multi-organ failure. She was brought to the operating room to undergo video-assisted thoracoscopy …

Office of the Provost

Evidence from Mendelian randomization studies suggest that lipoprotein(a) (Lp(a)) has a causal role in the development of atherosclerotic cardiovascular disease risk. However, guidelines and consensus statement recommendations vary regarding how clinicians should incorporate Lp(a) into patient care. To provide practical answers to key questions pertaining to Lp(a) that clinicians will find useful when assessing and treating patients, a global think tank was convened. Representatives from seven national and international stakeholder organizations answered questions that were focused on: Lp(a) measurement; ethnic, gender, and age considerations; factoring Lp(a) into risk assessment; and current and emerging treatment options for elevated Lp(a). This manuscript …

The COVID-19 pandemic initially brought forth considerable challenges to the field of heart transplantation. To prevent the spread of the virus and protect immunocompromised recipients, our center made the following modifications to post-transplant outpatient management: eliminating early coronary angiograms, video visits for postoperative months 7, 9, and 11, and home blood draws for immunosuppression adjustments. To assess if these changes have impacted patient outcomes, the current study examines 1-year outcomes for patients transplanted during the pandemic. Between March and September 2020, we assessed 50 heart transplant patients transplanted during the pandemic. These patients were compared to patients who were transplanted …

The Undesirable Communication: A Case Of Cerebral Air Emboli In The Setting Of Atrio-Esophageal Fistula Following Atrial Fibrillation Catheter Ablation, Momin Islam, Hussam Al Hennawi, Anwar Khedr, Khaled Harmouch, Mohammad F. Mathbout Jul 2022

The Undesirable Communication: A Case Of Cerebral Air Emboli In The Setting Of Atrio-Esophageal Fistula Following Atrial Fibrillation Catheter Ablation, Momin Islam, Hussam Al Hennawi, Anwar Khedr, Khaled Harmouch, Mohammad F. Mathbout

Abington Jefferson Health Papers

Atrial-esophageal fistula is an extremely rare condition but is often a deleterious complication following catheter ablation for atrial fibrillation. The associated iatrogenic communication acts as a conduit for air and bacterial translocation, which may lead to cerebral air embolism and polymicrobial sepsis, respectively. Coupled with a history of invasive procedures, the diagnosis is largely based on the accompanying neurological symptoms. In this report, we present the case of a 73-year-old female who presented with neurological deficits attributed to cerebral vascular emboli three weeks after catheter ablation for the treatment of chronic atrial fibrillation.

Myocardial Scintigraphy In Diagnosing Cardiac Transthyretin Amyloidosis, Marija Petrovic, Persio D Lopez, Calvin Eng, Mahjabeen Rashid

The Texas Heart Institute Journal

Myocardial scintigraphy with technetium-99m pyrophosphate is a minimally invasive technique that can distinguish between transthyretin amyloidosis (ATTR) and light-chain amyloidosis. We present a case in which it helped determine the amyloidosis type in a 74-year-old man with cardiac amyloidosis and multiple previous admissions for acute decompensated heart failure. The patient presented with increasing abdominal girth and bilateral lower extremity edema. His medical history also included atrial fibrillation, liver cirrhosis, hypertension, stage 3 chronic kidney disease, and peripheral vascular disease. We prescribed guideline-directed medical therapy for his acute decompensated heart failure with cardiorenal syndrome and his decompensated cirrhosis. Two years previously, …

Papillary Fibroelastoma Incidentally Found On Left Atrial Wall During Minimally Invasive Aortic Valve Replacement, Qasim Al Abri, Lamees I El Nihum, M Mujeeb Zubair, Roberto Barrios, Michael J Reardon, Mahesh Ramchandani

The Texas Heart Institute Journal

A 60-year-old man was about to undergo minimally invasive aortic valve replacement when transesophageal echocardiography revealed an intracardiac mass on the left atrial free wall. Multimodal images from 5 months earlier had shown no mass. We converted the procedure to open surgery. The excised mass resembled a cardiac myxoma but was determined to be a papillary fibroelastoma. This case illustrates that papillary fibroelastomas can form and grow rapidly, warranting alertness for their unexpected discovery before and during cardiac surgical procedures.


Palliative Stenting Of The Venous Duct In A Premature Neonate With Obstructed Infradiaphragmatic Total Anomalous Pulmonary Venous Connection, John S. Lozier, Martin L. Bocks Jul 2022

Palliative Stenting Of The Venous Duct In A Premature Neonate With Obstructed Infradiaphragmatic Total Anomalous Pulmonary Venous Connection, John S. Lozier, Martin L. Bocks

Faculty Scholarship

In infracardiac, infradiaphragmatic total anomalous pulmonary venous connection, all four pulmonary veins connect to a descending vertical vein that usually drains to the portal vein or one of its tributaries. Obstruction is common, and definitive treatment is surgical repair. We present a case of late-diagnosed infradiaphragmatic total anomalous pulmonary venous connection in a premature neonate who was too high risk for surgery and underwent palliative stenting of the venous duct. We demonstrate the feasibility of a transhepatic approach when umbilical access is no longer available.

Prolonged Cardiac Nr4a2 Activation Causes Dilated Cardiomyopathy In Mice, Sadia Ashraf, Heinrich Taegtmeyer, Romain Harmancey

Faculty, Staff and Student Publications

Transcription factors play a fundamental role in cardiovascular adaptation to stress. Nuclear receptor subfamily 4 group A member 2 (NR4A2; NURR1) is an immediate-early gene and transcription factor with a versatile role throughout many organs. In the adult mammalian heart, and particularly in cardiac myocytes, NR4A2 is strongly up-regulated in response to beta-adrenergic stimulation. The physiologic implications of this increase remain unknown. In this study, we aimed to interrogate the consequences of cardiac NR4A2 up-regulation under normal conditions and in response to pressure overload. In mice, tamoxifen-dependent, cardiomyocyte-restricted overexpression of NR4A2 led to cardiomyocyte hypertrophy, left ventricular dilation, heart failure, …

BACKGROUND: Cardiac surgery studies have established the clinical relevance of personalised arterial blood pressure management based on cerebral autoregulation. However, variabilities exist in autoregulation evaluation. We compared the association of several cerebral autoregulation metrics, calculated using different methods, with outcomes after cardiac surgery.

METHODS: Autoregulation was measured during cardiac surgery in 240 patients. Mean flow index and cerebral oximetry index were calculated as Pearson's correlations between mean arterial pressure (MAP) and transcranial Doppler blood flow velocity or near-infrared spectroscopy signals. The lower limit of autoregulation and optimal mean arterial pressure were identified using mean flow index and cerebral oximetry index. …

Obscurin Regulates Ankyrin Macromolecular Complex Formation, Janani Subramaniam, Gokay Yamankurt, Shane R Cunha

Faculty, Staff and Student Publications

Obscurin is a large scaffolding protein in striated muscle that maintains sarcolemmal integrity and aligns the sarcoplasmic reticulum with the underlying contractile machinery. Ankyrins are a family of adaptor proteins with some isoforms that interact with obscurin. Previous studies have examined obscurin interacting with individual ankyrins. In this study, we demonstrate that two different ankyrins interact with obscurin's carboxyl terminus via independent ankyrin-binding domains (ABDs). Using in-vitro binding assays, co-precipitation assays, and FLIM-FRET analysis, we show that obscurin interacts with small ankyrin 1.5 (sAnk1.5) and the muscle-specific ankyrin-G isoform (AnkG107). While there is no direct interaction between sAnk1.5 and AnkG107, …
