What Did We Learn About Vads In 2022?, Maya Guglin

The VAD Journal

This is our 9th annual literature review on mechanical circulatory support devices. Our previous reports were well received by the readers.

In this paper, we summarized the most interesting and important, from our standpoint, publications from 2022. There may be some slight overlap with the end of 2021 because some papers were published online first, and the year of the publication changed when they became available in print.

For the sixth time, we wrote a section on extracorporeal membrane oxygenation (ECMO) which primarily addresses new developments in veno-arterial ECMO.

Readers who wish to supplement this review, argue with the …

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 2023 Department of Medicine and Geriatrics, Princess Margaret Hospital, Hong Kong

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 2023 Pro-Care Heart Clinic

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.

Case Study: Abnormal Presentation Of Infective Endocarditis With Streptococcus Canis And Chiari Network, Shahbaz Afzal, Ryan Russell, Alexander Chekhov

Advances in Clinical Medical Research and Healthcare Delivery

Here we present a rare case of infective endocarditis (IE) with Streptococcus canis and Chiari network in an 85 year old female living with multiple dogs and open skin of lower extremity predisposing her to bacteremia. Underlying abnormalities of the cardiac chambers such as Chiari network predisposes to a higher incidence of bacterial seeding and causing IE. A Chiari network is usually asymptomatic and of no clinical significance but can worsen prognosis in IE. IE carries a significant morbidity and mortality burden and when diagnosed early can be a lifesaving diagnosis. Due to the wide range of complications, early diagnosis …

A nation’s health and economic development are inextricably and synergistically connected. Stark differences exist between wealthy and developing nations in the use of cardiac implantable electronic devices (CIEDs). Cardiovascular disease is now the leading cause of death in low- and middle-income countries (LMIC), with a significant burden from rhythm-related diseases. As science, technology, education, and regulatory frameworks have improved, CIED recycling for exportation and reuse in LMIC has become possible and primed for widespread adoption. In our manuscript, we outline the science and regulatory pathways regarding CIED reuse. We propose a pathway to advance this technology that includes creating a …

Stem cell therapy can be beneficial following myocardial infarction. However, when murine bone marrow-derived mesenchymal stem cells (mBM-MSCs) are injected into the ischemic area, a large percentage of these cells undergo apoptosis resulting in decreased therapeutic benefits. We hypothesize that the loss of these mBM-MSCs is regulated by intercellular channels or gap junctions (GJs) that provide apoptotic signals passed between ischemic cardiomyocytes and mBM-MSCs. Our research aims to attenuate these GJs by suppressing Connexin-43 (Cx43) expression, the predominant channel-forming protein. We will accomplish this by transiently transfecting a Cx43 siRNA into mBM-MSCs. Our data demonstrate that intracellular fluorescent dyes and …
