To compare the utility of non-fluoroscopic mapping systems (Carto and Ensite NavX) with that conventional in patients referred for catheter ablation a wide variety arrhythmias.Patients (excluding atrial fibrillation, atypical flutter, ventricular tachycardia structural heart disease, complete AV nodal ablation) were randomized equally to procedure guided by Carto, NavX, or mapping. A total 145 recruited (82 men, aged 49+/-16, range 18-85). In 19 patients, no was performed, remaining, typical...

Thrombo-embolic complications after Corona virus disease-19 (COVID-19) vaccination have been previously reported. We aimed to study the coronary thrombo-embolic (CTE) COVID-19 in a single centre during initial 3 months of drive India. All patients admitted our hospital between 1st March 2021 and 31st May with Acute syndrome (ACS) were included. Of 89 [Age 55 (47-64)y, 13f] ACS angiographic evidence thrombus, 37 (42%) had prior history. The timing from last dose index event was <1, 1-2, 2-4...

Pulmonary veno-occlusive disease (PVOD) is a disorder which causes progressive pulmonary hypertension, usually presenting with worsening dyspnoea and right heart failure. oedema induced by vasodilator therapy to reduce arterial pressure has been well described in PVOD, but here we describe case of PVOD recurrent episodes acute non-cardiogenic oedema, the absence significant hypertension. Concern over risk precipitating led us use inhaled nitric oxide predict safety efficacy sildenafil.

Few studies from various countries have reported decline in Acute Coronary Syndrome (ACS) admissions to hospital during COVID-19 pandemic. We studied the impact of strict lockdown on ACS admission a tertiary referral India. This showed 43% (n = 104 vs mean n 183) and even those who got admitted, there was delay presentation compared previous year, which reflected outcome patients. Government health organizations should educate public early-on pandemic about consequences ignoring other acute...

Aims:To characterise the clinical course of patients who had incidental findings on CT aortogram (CTA) done as a transcatheter aortic valve implantation (TAVI) work-up investigation. Methods and results:All underwent CTA investigation for TAVI were retrospectively recruited (n=295, 83±6.7 years) to identify those with an finding.A total 323 identified in 201 (68.1%) patients.Of findings, 87 (43.3%) at least one immediate significance.Within this group, fewer (52.9%) eventually compared...

The impact of coronavirus disease 2019 (COVID-19) lockdown on cardiac emergency admissions to hospitals has been reported previously. We aimed study the room (ER) intensive care unit (CICU) at a tertiary center during that period and compare this with same time frame in previous years.This is retrospective observational patients admitted CICU pandemic from March 22 August 1 (inclusive) 2020 compared 2 years (2018 2019).During 2020, total 216 (age 59 ± 14 years) were via ER, which 33% 30%...

Rotational atherectomy (rotablation) of coronary artery is relatively contraindicated in high thrombotic state such as acute ST-elevation myocardial infarction (STEMI) because the risk platelet activation by rotablator. We present a case where rotablation was necessary to recanalize right patient presenting with STEMI complicated cardiogenic shock, after unsuccessful attempts balloon catheters. He improved remarkably procedure and discharged 4 days.

Catheter ablation (CA) has become the treatment of choice for regular supraventricular tachycardia (SVT). The purpose this study was to investigate whether current clinical results in a large single centre are as good success rates quoted patients from published trials and national cardiology society websites.We recorded analysed prospectively acute follow-up (FU) all CA procedures performed SVT at our institution over 2-year period. We compared with 90-98% literature. total 547 2 years,...

A 21-year-old woman was admitted to our unit with suspected infective endocarditis. Transthoracic and transoesophageal echocardiogram demonstrated vegetation in a parachute-like asymmetrical mitral valve severe regurgitation. She completely asymptomatic before this presentation. Though there no evidence of stenosis, deformity is associated transvalvular turbulence, which would account for the increased likelihood underwent prosthetic replacement 21 mm ATS mechanical valve.

An 82-year-old gentleman with situs inversus and dextrocardia was admitted to our unit following thrombolysis for inferior ST-elevation myocardial infarction (STEMI). Due ongoing ischemic symptoms, he underwent emergency transradial coronary angiography. His culprit right artery (RCA) heavily calcified severe stenosis in the mid distal segments. Therefore, rotational atherectomy performed debulking, four drug eluting stents were deployed RCA. To best of knowledge, this is first reported case...
