Utility of late gadolinium enhancement on magnetic resonance imaging in hypertrophic cardiomyopathy patients in an Indian cohort.

This prospective observational study sought to correlate segmental late gadolinium enhancement (LGE) seen in cardiac magnetic resonance imaging with occurrence of ventricular arrhythmias (VAs) in patients with hypertrophic cardiomyopathy. LGE was assessed in a 17-segmental model of heart. Of 57 patients, VAs were present in 26.

Aneurysmal and obstructive lesions of the left ventricular outflow: evaluation on multidetector computed tomography angiography.

The left ventricular outflow is an anatomically complex region situated between the anterior leaflet of the mitral valve and the left ventricular aspect of the muscular and membranous interventricular septum. It gives rise to the aorta, provides support to the aortic valvular cusps, and houses important components of the conduction system. The left ventricular outflow handles high pressures and pressure variations and is subsequently affected by a variety of aetio-pathological conditions.

Supravalvar aortic stenosis: Imaging characteristics and associations on multidetector computed tomography angiography.

Aim: To evaluate the imaging features and associations in patients with supravalvar aortic stenosis on multidetector computed tomography (CT) angiography.

Materials And Methods: We retrospectively reviewed all CT angiography studies performed for evaluation of congenital heart diseases at our institution through the period from January 2014 to June 2020. Cases with supravalvar aortic stenosis were identified and classified as syndromic and nonsyndromic based on history, physical examination, and relevant investigations.

Prognostic role of procalcitonin in ST-elevation myocardial infarction complicated by cardiogenic shock.

Objective: Cardiogenic shock accounts for the majority of deaths amongst patients with ST-elevation myocardial infarction. Procalcitonin is elevated in acute myocardial infarction, especially when complicated by left heart failure, cardiogenic shock, resuscitated cardiac arrest, and bacterial infections. However, the prognostic utility of procalcitonin in ST-elevation myocardial infarction complicated by cardiogenic shock has not been systematically evaluated.

The time to reversal of complete atrioventricular block and its predictors in acute ST-segment elevation myocardial infarction.

Objective: The purpose of this study was to determine the time to reversal of complete AV block (CAVB) in ST-segment elevation myocardial infarction (STEMI) with various modalities of treatment and to examine the factors associated with early reversal of CAVB.

Methods: We prospectively assessed the STEMI patients complicated by CAVB. The mean time to reversal of CAVB was analyzed and compared according to the treatment received.

Isolation of arch vessels: Imaging characteristics and associations on multidetector computed tomography angiography.

Aim: To evaluate the imaging characteristics and associations in patients with isolation of arch vessels on multidetector computed tomography angiography (CTA).

Materials And Methods: We retrospectively reviewed all multidetector CTA studies performed for the evaluation of congenital heart diseases (CHDs) at our institution from January 2014 to June 2020. Cases with isolation of arch vessels were identified.

Refractory axillary venous spasm during permanent pacemaker implantation.

Background: Vascular spasm is well known to occur in the arterial system. Central venous spasm during pacemaker implantation is uncommon with only a few cases reported from time to time. Sometimes, the venous spasms may not respond to nitroglycerine injections which requires a change of access site and undue discomfort for the patient.

An unexpected complication of intracardiac device implantation: Contralateral pneumothorax and pneumopericardium.

A 62-year-old man developed concomitant right-sided pneumothorax and pneumopericardium after undergoing implantation of a left-sided dual-chamber pacemaker. The case is reported for its rarity. The possible mechanisms and management options for this extremely rare complication are discussed.
