Our goal was to describe clinical, treatment profile, and predictors of outcome in children with acute fulminant myocarditis (AFM) receiving intensive care. Case records of 120 children with clinical diagnosis of acute myocarditis from January 2008 to December 2018 were analyzed retrospectively.

Saline as an Alternative to Radio-Contrast for Optical Coherence Tomography-Guided Percutaneous Coronary Intervention: A Prospective Comparison.

Objectives: To do a quantitative comparison of saline and contrast Frequency domain optical coherence tomography (FD-OCT) during percutaneous coronary intervention (PCI) optimisation.

Methods: 13 pairs of OCT runs were analysed, wherein each pair consisted of a contrast run and a heparinized saline run taken in the same coronary artery at the same position. Quantitative analysis was done comparing minimal lumen area (MLA), proximal reference diameter (PRD), distal reference diameter (DRD) and percentage area stenosis (AS) at the same anatomical location.

An unusual precipitant of acute heart failure-ANCA-associated vasculitis in a patient with ischaemic cardiomyopathy: a case report.

Background: Antineutrophil cytoplasmic antibody (ANCA)-associated pulmonary renal vasculitis is an uncommon disease entity. Its presentation as acute heart failure for the first time in a patient with established coronary artery disease (CAD) is even rarer. We present here a case of such an association and an approach to managing this clinical situation.

Role of Intravascular Imaging for the Diagnosis of Recanalized Coronary Thrombus.

Introduction: Recanalized thrombus (RCT) of coronary arteries is frequently unrecognized in interventional cardiology practice. Intravascular imaging conclusively establishes its diagnosis, which otherwise is often misdiagnosed as fresh thrombus, spontaneous coronary artery dissection, or severe calcification based on angiography, alone. We hereby report our experience of 10 RCT patients, who had the intravascular imaging-guided diagnosis, followed by the successful percutaneous coronary intervention (PCI).

Hydroxychloroquine and QTc prolongation in patients with COVID-19: A systematic review and meta-analysis.

Background: Among many drugs that hold potential in COVID-19 pandemic, chloroquine (CQ), and its derivative hydroxychloroquine (HCQ) have generated unusual interest. With increasing usage, there has been growing concern about the prolongation of QTc interval and Torsades de Pointes (TdP) with HCQ, especially in combination with azithromycin.

Aims: This meta-analysis is planned to study the risk of QTc prolongation and Torsades de pointes (TdP) by a well-defined criterion for HCQ, CQ alone, and in combination with Azithromycin in patients with COVID-19.

Is there a transcatheter solution for a sick neonate with hypoplastic right heart syndrome?: Pulmonary valve perforation in a neonate with hypoplastic right ventricle with pulmonary atresia, restrictive VSD-a case report.

Background: Hypoplastic right heart syndrome with pulmonary atresia is a rare cyanotic heart disease with poor prognosis requiring urgent intervention to establish the pulmonary blood flow. Pulmonary blood flow is achieved by BT shunt or percutaneous techniques like PDA stenting or pulmonary valve perforation. Various series have shown that early surgical intervention causes high mortality in these patients.

Study of saline optical coherence tomography-guided percutaneous coronary intervention (SOCT-PCI Study).

Aim: The aim of this study was to evaluate the feasibility of heparinised saline as flushing media for frequency-domain optical coherence tomography (FD-OCT) image acquisition during percutaneous coronary intervention (PCI) optimisation.

Methods And Results: Twenty-seven patients undergoing FD-OCT-guided PCI were enrolled. Heparinised saline was injected into the coronary during FD-OCT image acquisition.

Percutaneous Coronary Revascularization in Patients With Single Coronary Artery.

Introduction: Single coronary artery (SCA) is a rare congenital coronary anomaly. Its incidence in various angiographic series is from 0.024% to 0.

Percutaneous coronary intervention of anomalous left circumflex coronary artery - A case series.

We report a case series of 14 cases (mean age 54.14 ± 14.75 years) of successful percutaneous coronary intervention of anomalous left circumflex artery.

Optical Coherence Tomography Imaging in Acute Myocardial Infarction: Calcified Nodule as a Culprit Lesion.

A calcified nodule is an infrequent pathological substrate in acute coronary syndrome patients. This case demonstrates the technical challenges of intervening an eccentric, severely calcified, balloon-uncrossable coronary lesion.

An uncommon overlap of two common rheumatological disorders.

Juvenile systemic lupus erythematosus (SLE) is a heterogeneous multisystem autoimmune disease. Kawasaki disease is a common vasculitic disorder in children that manifests with fever and mucocutaneous involvement. While overlap of childhood SLE with other rheumatological disorders has been described, it is extremely unusual in the context of Kawasaki disease.

Endovascular Treatment of a Migrated Superior Vena Cava Stent in the Right Atrium.

A 42-year-old female with end-stage chronic kidney disease, who was on maintenance hemodialysis for the last 3 years, presented with facial and upper-limb swelling of 2-month duration. A computed tomography (CT) scan confirmed significant stenosis of the superior vena cava (SVC). Following discussion in a multidisciplinary meeting, it was proposed to perform a repeat endovascular intervention to relieve the SVC obstruction and manage the migrated stent.

Footprint of a Bioresorbable Vascular Scaffold in Computed Tomography Coronary Angiogram at 5-Year Follow-up.

The Absorb bioresorbable vascular scaffold (Abbott Vascular) does not have an artifact on computed tomography coronary angiography (CTCA); the extent/location of the stent in situ can only be assessed by localizing its radiopaque platinum markers in a non-contrast CTCA. The characteristic appearance of BVS on CTCA should be interpreted as the footprint of a resorbed BVS, instead of a calcified plaque.

Clinical characteristics and outcome in patients with a delayed presentation after ST-elevation myocardial infarction and complicated by cardiogenic shock.

Objective: Delayed presentation after ST-elevation myocardial infarction (STEMI) and complicated by cardiogenic shock (CS-STEMI) is commonly encountered in developing countries and is a challenging scenario because of a delay in revascularization resulting in infarction of a large amount of the myocardium. We aimed to assess the clinical characteristics, angiographic profile, and predictors of outcome in patients with a delayed presentation after CS-STEMI.

Methods: A total of 147 patients with CS-STEMI with time to appropriate medical care ≥12 h after symptom onset were prospectively recruited at a tertiary referral center.

Asymptomatic, Multiple Stent Fractures of a Superficial Femoral Artery.

Certain factors like ostial disease, chronic total occlusion, and long, multiple stents are the main causes of multiple stent fractures, as were present in this case. Such stent fractures are usually associated with significant in-stent restenosis; however, this patient had a patent lumen despite multiple fractures.
