Severe pulmonary arterial hypertension in congenital sideroblastic anemia from PUS1 mutation - a case report.

Background: Myopathy, lactic acidosis and inherited sideroblastic anemia (MLASA) are a group of rare intriguing disorders with wider pathophysiological implications. One of the causes of MLASA is the mutation in PUS1 gene that encodes for pseudouridine synthase. This PUS1 mutation results in MLASA in which anemia and myopathy predominate.

Analysis of ST segment depression in supraventricular tachycardia and its relationship with underlying mechanism.

Background: Electrocardiographic diagnosis of causes of supraventricular tachycardia (SVT) is sometimes difficult and application of routine algorithms can lead to misdiagnosis in as many as 37 % of patients. ST segment depression may be useful in diagnosing the nature of SVT.

Methods: We reviewed surface electrocardiogram (ECG) characteristics of 300 patients having SVT with 1:1 AV relationship and correlated findings with electrophysiology study (EPS) findings.

An Unusual Presentation of Takotsubo Cardiomyopathy: A Case Report.

Tachyarrhythmias have been well-defined in patients with Takotsubo cardiomyopathy (TTCM) and are estimated to occur in almost 13.5% of patients. However, limited data are available on bradyarrhythmias in patients with TTCM.

Retrieval of a severely double-kinked catheter in the right brachial artery by internal fixation with a peripheral angioplasty balloon.

A 55-year-old female patient with unstable angina and accelerated hypertension was planned for invasive coronary and renal angiogram.

Incidence, clinical characteristics, electrophysiological characteristics and outcomes of patients with baseline PR prolongation undergoing radiofrequency ablation for Atrioventricular nodal reentrant tachycardia.

Aims And Objectives: Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common supraventricular tachycardia (SVT). Prolonged PR interval(>200 ms) on baseline electrocardiogram (ECG) is uncommon in such patients. The aim of the current study was to evaluate the incidence, clinical, electrophysiological characteristics, and outcomes of patients with baseline prolongation of PR interval undergoing radio-frequency ablation (RFA) for AVNRT.

Significance of myocardial injury on in-hospital clinical outcomes of in-hospital and COVID-19 patients.

Introduction: Acute Myocardial injury defined by increased troponin I level is associated with poor in-hospital outcomes and cardiovascular complications in patients with COVID-19. The current study was designed to determine the implications and clinical outcome of myocardial injury in COVID-19.

Methods: This retrospective study included hospitalized COVID-19 patients.

Re-intervention percutaneous balloon mitral valvuloplasty in a patient with left atrial appendage thrombus: a case report.

Background: Percutaneous balloon mitral valvuloplasty (PBMV) using an Accura balloon is an effective method for management of rheumatic mitral stenosis.

Case Summary: Herein, we present a case of a 43-year-old female, who had undergone a previous PBMV, who presented with very severe mitral re-stenosis with Type Ia left atrial (LA) clot, in atrial fibrillation and New York Heart Association functional Class III. We used the modified septal puncture and over-the-wire technique, avoiding inadvertent manipulation of the LA clot for PBMV.
