Novel Cause Of Late Atrial Septal Defect Devices Embolization, Wejdan Ba-Atiyah, Hala Gabel, Ahmad Jamjoom, Jameel Al-Ata Mar 2023

Novel Cause Of Late Atrial Septal Defect Devices Embolization, Wejdan Ba-Atiyah, Hala Gabel, Ahmad Jamjoom, Jameel Al-Ata

Journal of the Saudi Heart Association

Transcatheter closure of septal defects using specialized devices is a common procedure that has a high success rate. Embolization of Atrial septal defect devices is a known complication seen at a rate of 0.5%. We report a case of late ASD device occluder embolization immediately after brain MRI with clinical consequences and intraoperative evidence of right atrial wall thermal injury. To our knowledge Atrial septal occluder (ASO) device embolization post magnetic resonance imaging (MRI) was not reported before, although theoretically possible and that's why six to eight weeks post device implantation MRI is prohibited even with current MRI compatible devices.

High Output Heart Failure, A Lethal And Forgotten Cause Of Heart Failure, Neiberg A. Lima Md, Ian Detroyer Bs, Saman Razzaq Md, Oluwale Adegbala Md, Preeti Ramappa Md

Medical Student Research Symposium

Introduction

Cardiac output (CO) is usually low or normal in patients with heart failure. However, some patients have a high CO deemed high-output heart failure (HOHF). HOHF is not well characterized and continues to be under-recognized clinically. At the Detroit VA, we conducted a quality improvement project to define the characteristics of this unique patient population, identify predictors and increase awareness of this entity.

Methods

Patients with HOHF were compared to patients with heart failure with preserved ejection fraction (HFpEF) and normal CO. HOHF was defined as CO >8 L/minute on right heart catheterization performed between 2008-2021. Retrospective data regarding …

Better Survival In Morbidly Obese Patients With Atrial Fibrillation Treated With Non-Vitamin K-Dependent Oral Anticoagulants, Monirah A. Albabtain, Zaid Alanazi, Nawaf Al Mutairi, Yahya Al Hebaishi, Ola Alyafi, Haneen Alghasoon, Amr A. Arafat Mar 2023

Better Survival In Morbidly Obese Patients With Atrial Fibrillation Treated With Non-Vitamin K-Dependent Oral Anticoagulants, Monirah A. Albabtain, Zaid Alanazi, Nawaf Al Mutairi, Yahya Al Hebaishi, Ola Alyafi, Haneen Alghasoon, Amr A. Arafat

Journal of the Saudi Heart Association

Background: The efficacy and safety of non-vitamin K-dependent anticoagulants (NOAC) are not well investigated in the obese population, and fixed dosing could lead to under-anticoagulation. Our objective was to evaluate the effect of obesity on anticoagulation outcomes and survival in non-valvular atrial fibrillation (AF) patients. Methods: We enrolled 755 patients who required anticoagulation for AF from 2015 to 2016. We grouped the patients into four groups. Group 1 (n= 297) included patients with BMI< 40 Kg/m2 treated with NOACs, Group 2 (n= 358) included patients on warfarin with BMI< 40 Kg/m2, Group 3 (n= 57) had patients on NOACs with BMI≥ 40 Kg/m2 and Group 4 (n= 43) included patients on warfarin and BMI≥ 40 Kg/m2. Study outcomes were the composite endpoint of stroke, bleeding, and survival. Results: Competing risk regression showed that stroke and bleeding were not affected by obesity or treatment (SHR: 1.09 (95% CI: 0.79- 1.51); P= 0.62). Older age was the predictor of stroke/bleeding (HR:1.03 (95% CI:1.01- 1.06); P= 0.02). Predictors of mortality were heart failure (HR:2.23 (95% CI:1.25- 3.97); P= 0.007), lower creatinine clearance (HR: 0.98 (95% CI:0.97- 0.98): P< 0.001), non-obese patients on warfarin (HR:3.51 (95%CI:1.6- 7.7): P=0.002) and obese patients on warfarin (HR: 6.7 (95% CI:2.51- 17.92); P< 0.001). Conclusion: NOACs could have a similar risk profile to warfarin in obese and non-obese patients with non-valvular AF but could have better survival. Larger randomized trials are recommended.

Complications Of Cardiopulmonary Bypass From An Anesthesia Perspective: A Clinical Review, Alex Roberts, Elizabeth C. Duncan, Paul Hargrave, David Redding Kingery, Josh Barnes, Derek L. Horstemeyer, Russell F. Stahl

HCA Healthcare Journal of Medicine

Cardiopulmonary bypass (CPB) is frequently used for open heart surgery and other procedures that utilize temporary substitution or support of heart and lung function. While it is widely accepted as the predominant method to carry out these procedures, it is not without possible complications. CPB can be seen as the ultimate “team sport” as it includes and is dependent on contributions from multiple professionals including anesthesiologists, cardiothoracic surgeons, and perfusion technicians. In this clinical review paper, we examine possible complications of CPB, primarily from the perspective of the anesthesiologist, and how to troubleshoot them if they arise, which often requires …

Akay

Journal of Shock and Hemodynamics

Patients with advanced heart failure require multi-system management as a majority succumb to end-organ dysfunction, including gastrointestinal sequelae. Temporizing measures, such as early mechanical circulatory support, can assist in the recovery of patients with acute cardiogenic shock. The temporary support can improve patient characteristics to enable future definitive heart failure therapies such as durable left ventricular assist devices and orthotopic heart transplantation. We present two cases of cardiogenic shock that were successfully bridged with an Impella 5.5 (Abiomed). The management enabled the patients to recover from reversible cardiointestinal syndrome and undergo successful definitive therapies.


Revascularization In Cardiogenic Shock: Residual Syntax Score And Chronic Total Occlusions, Venugopal Menon Feb 2023

Revascularization In Cardiogenic Shock: Residual Syntax Score And Chronic Total Occlusions, Venugopal Menon

Journal of Shock and Hemodynamics

The residual syntax score (rSS) is strongly associated with outcomes in patients with stable coronary artery disease. In patients with acute myocardial infarction-associated cardiogenic shock (AMI-CS), the correlation or association of the rSS, mortality risk, and revascularization strategy has not yet been elucidated and needs more investigation. The SHOCK trial demonstrated that patients with left main and severe triple-vessel disease, who underwent coronary artery bypass grafts, had improved outcomes and higher 1-year survival rates than those with initial medical stabilization. However, it is unclear which is the superior technique for achieving complete revascularization. In contrast to the SHOCK trial’s results, …


Covid-19 Induced Right Ventricular Failure And Right Ventricular Assist Device Support, Marvin Slepian M.D. Feb 2023

Covid-19 Induced Right Ventricular Failure And Right Ventricular Assist Device Support, Marvin Slepian M.D.

Journal of Shock and Hemodynamics

COVID-19, while primarily recognized for its pulmonary and systemic manifestations, afflicts the cardiovascular system through various abnormalities. Notably, right ventricular (RV) involvement leading to dysfunction and failure is a manifestation seen in up to 20% of severe COVID patients. RV severity correlates with overall COVID severity, serving as a prognostic marker. Data review reveals that RV failure was largely underdiagnosed, particularly early on in the pandemic. The therapy approach for RV failure in patients with COVID should focus on supporting overall RV perfusion pressure, maintaining sinus rhythm, optimizing RV loading conditions and contractility, and addressing anticoagulation and thrombus-related conditions. Beyond …


Right Ventricular Hemodynamics In Covid-19 Patients, Steven Hollenberg Feb 2023

Right Ventricular Hemodynamics In Covid-19 Patients, Steven Hollenberg

Journal of Shock and Hemodynamics

The right ventricle is highly sensitive to afterload, and pulmonary compromise can increase pulmonary vascular resistance and lead to right ventricular dysfunction. Pulmonary hypertension can also be exacerbated by mechanical ventilation. Patients with COVID-19 pneumonia and respiratory failure, especially those ventilated with positive end-expiratory pressure, are prone to pulmonary hypertension. Understanding their right ventricular hemodynamics can have therapeutic and prognostic implications.


Current And Emerging Therapies For Atherosclerotic Cardiovascular Disease Risk Reduction In Hypertriglyceridemia, Reed Mszar, Sarah Bart, Alexander Sakers, Daniel Soffer, Dean G. Karalis Feb 2023

Current And Emerging Therapies For Atherosclerotic Cardiovascular Disease Risk Reduction In Hypertriglyceridemia, Reed Mszar, Sarah Bart, Alexander Sakers, Daniel Soffer, Dean G. Karalis

Division of Cardiology Faculty Papers

Hypertriglyceridemia (HTG) is a prevalent medical condition in patients with cardiometabolic risk factors and is associated with an increased risk of atherosclerotic cardiovascular disease (ASCVD), if left undiagnosed and undertreated. Current guidelines identify HTG as a risk-enhancing factor and, as a result, recommend clinical evaluation and lifestyle-based interventions to address potential secondary causes of elevated triglyceride (TG) levels. For individuals with mild to moderate HTG at risk of ASCVD, statin therapy alone or in combination with other lipid-lowering medications known to decrease ASCVD risk are guideline-endorsed. In addition to lifestyle modifications, patients with severe HTG at risk of acute pancreatitis …

Coronary Flow And Unloading In Acute Myocardial Infarction Shock, Kiyo Ishikawa Feb 2023

Coronary Flow And Unloading In Acute Myocardial Infarction Shock, Kiyo Ishikawa

Journal of Shock and Hemodynamics

In patients with cardiogenic shock that undergo successful coronary intervention, there are still factors complicating myocardial recovery. There is room for improvement in coronary flow using mechanical circulatory devices, specifically by left ventricular unloading. This idea was further explored in a research study using pigs. Results showed that subjects with acute myocardial infarction who have reduced cardiac contractility and/or high diastolic pressure would benefit from support strategies targeting left ventricular unloading.

Reducing The Risk Of Mortality In Chronic Obstructive Pulmonary Disease With Pharmacotherapy: A Narrative Review, Matthew Mintz, Igor Barjaktarevic, Donald A. Mahler, Barry Make, Neil Skolnik, Barbara Yawn, Bree Zeyzus-Johns, Nicola A. Hanania

Abington Jefferson Health Papers

In 2020, chronic obstructive pulmonary disease (COPD) was the fifth leading cause of death in the United States excluding COVID-19, and its mortality burden has been rising since the 1980s. Smoking cessation, long-term oxygen therapy, noninvasive ventilation, and lung volume reduction surgery have had a beneficial effect on mortality; however, until recently, the effects of pharmacologic therapies on all-cause mortality have been unclear. Inhaled pharmacologic treatments for patients with COPD include combinations of long-acting muscarinic receptor antagonists (LAMAs), long-acting-β2-agonists (LABAs), and inhaled corticosteroids (ICS). The recent IMPACT and ETHOS clinical trials reported mortality benefits with ICS/LAMA/LABA triple therapy compared with …

Journal of the Hong Kong College of Cardiology

Post myocardial infarct polymorphic Ventricular Tachycardia (VT) triggered by injured Purkinje fibres can cause VT storms that are refractory to various treatment even after successful reperfusion or revascularization. We reported such recurrent polymorphic VT in two post myocardial infarct patients after Percutaneous Coronary Intervention. Both of them responded readily to Quinidine. We also discussed the pathophysiology of this arrhythmia and the treatment option of it, namely catheter ablation and antiarrhythmics


Recurrent Cyanotic Spells In An Octogenarian, Chin Tong Kwok, Chun Kit Wong Jan 2023

Recurrent Cyanotic Spells In An Octogenarian, Chin Tong Kwok, Chun Kit Wong

Journal of the Hong Kong College of Cardiology

We report rare case of an octogenarian who, after years of diagnostic delay, was found to have a patent foramen ovale, and due to an ascending aortic aneurysm that anatomically facilitated right-to-left shunt, presenting with life-threatening cyanotic attacks. The characteristic orthodeoxia-platypnea syndrome and high alveolar arterial gradient hint to the diagnosis. She was eventually treated successfully with urgent percutaneous PFO closure. Routine ordering of a transthoracic echocardiogram, without agitated saline injection under provocation maneuvers, may not be sufficient to rule out shunts.


Roles Of Exercise Treadmill Test In The Diagnosis & Risk Stratification Of Cardiac Channelopathies, Kit Chan Jan 2023

Roles Of Exercise Treadmill Test In The Diagnosis & Risk Stratification Of Cardiac Channelopathies, Kit Chan

Journal of the Hong Kong College of Cardiology

Channelopathies are the leading causes of SCD in patients without structural heart disease. Missing the diagnosis of high-risk but concealed channelopathies could have lethal clinical consequences. However, the diagnosis of channelopathies is often challenging due to the dynamic clinical presentations and elusive ECG manifestations of these diseases. An integrated approach including clinical assessment, repeated electrocardiography, drug provocation tests, exercise stress test and genetic studies is often required for establishing the diagnosis. Pharmacological provocation tests may have limited sensitivity and may be associated with false positive results. Wide-spread use of genetic studies are limited by low yield, cost-effectiveness and availability issue. …

Predictors Of Neurological Complications Of Pediatric Post-Cardiotomy Extracorporeal Life Support, Hala Mounir Agha, Amr Fathalla, Giuseppe Isgro, Mauro Cotza

Journal of the Saudi Heart Association

Background: Post-cardiotomy extracorporeal membrane oxygenation (ECMO) was associated with significant neurological complications affecting the overall outcome. The aim of the work is to determine the incidence and the predictors of neurological events during pediatric extracorporeal life support after cardiac surgery. Patients & Methods: This is a retrospective study that encompassed all neonates, infants, and children (<18 years of age) who need extracorporeal life support following cardiac surgery between January 2015 and December 2018 at San Donato Hospital, Italy. Data as regards surgical procedure of congenital heart disease, in-hospital mortality, length of ECMO, hospital stay durations, short-term neurological ECMO complications and outcome were analyzed. Results: The sixty-three patients who received post-cardiotomy ECMO, Neurological complications were evident in 31.7% in the form of ischemic stroke in 17.5% and hemorrhagic stroke in 11.1%. By multivariable analysis, the older age of cyanotic cases, the need for a venting cannula, and the rapid CO2 drop in the first 24 h were the most independent risk factors for neurological complications. Prolonged ECMO support and hospital stay duration were associated with neurological sequelae. Conclusion: Neurological complications either ischemic or hemorrhagic strokes were common during pediatric postcardiotomy ECMO and were significantly related to prolonged ECMO support and hospital stay. Predictors of these neurological sequelae are the older cyanotic cases, the need for a venting cannula, the oxygenator thrombosis, and the rapid CO2 drop in the first 24 h of ECMO.
