Long-term outcomes of percutaneous coronary intervention in patients with prior coronary artery bypass graft - A retrospective experience.

Objective: To evaluate the long-term clinical outcomes of percutaneous coronary intervention (PCI) in patients who had previously undergone coronary artery bypass grafting (CABG).

Method: A total of 219 patients who had a history of CABG and underwent PCI at tertiary care centre were retrospectively enrolled in this study. Clinical endpoints such as major adverse cardiac events (MACE; cardiac death, non-fatal myocardial infarction [MI], and target vessel revascularization), any death, cardiac death, MI, target vessel revascularization (TVR), and target lesion revascularisation (TLR) were reported at long-term follow-up.

Long term outcomes after bare metal stent implantation.

Long term outcome data after BMS implant is not available from the Indian subcontinent. This is a prospective observational study which aims to study long term outcomes after BMS implant at a tertiary care centre. 100 consecutive patients underwent BMS implant and were followed up for 20 years.

Clinical Outcomes of patients with coronary artery disease who underwent FFR evaluation of intermediate coronary lesionS- COFFRS study.

Background: We undertook this study to validate the impact of FFR-guided coronary interventions among Indian patients, which is not readily available as of date. Our patients differ from their western counterparts, both in terms of risk profile (younger, more metabolic syndrome, lipid rich diet) as well as their coronary size.

Methods: We retrospectively evaluated 282 patients with intermediate stenosis in their coronary arteries, who underwent FFR to assess the functional severity of the lesion.

Unexpected complication of uncovered aortic end in ductal stenting.

A newborn with tricuspid atresia and pulmonary atresia underwent ductal stenting. The aortic end of the ductus was not completely covered and was wide open; the baby was discharged on dual antiplatelets. The baby presented after a month with desaturation, and an angiogram showed extensive thrombus in the stent and the right pulmonary artery.

Cervical origin of left subclavian artery: A rare anomaly.

A 22-year-old lady was referred to our institute for the management of pulmonary atresia with hypoplastic pulmonary arteries. Computed tomographic Angiography (CTA) showed right aortic arch with left brachicephalic artery as the first branch, which trifurcated into internal carotid, external carotid and subclavian artery high up in the neck at the level of third cervical vertebra. The left subclavian artery then travelled back caudally and entered into the arm after giving rise to a large collateral artery.

Cardiac rhabdomyoma in familial tuberous sclerosis.

Cardiac rhabdomyomas are often associated with tuberous sclerosis in infants. We report a 5 month old child presented with a tumor in the right ventricle and echocardiography features of rhabdomyoma. Both the child and her father had cutaneous features of tuberous sclerosis.

An unusual cause for unruptured sinus of valsalva aneurysm.

Sinus of valsalva aneurysm is considered to be one of the rarest complications of inflammatory aortitis. Herewith, we are reporting a young male patient who presented to us with severe aortic regurgitation. On evaluation, he was found to have unruptured sinus of valsalva aneurysm.

Association between gender, process of care measures, and outcomes in ACS in India: results from the detection and management of coronary heart disease (DEMAT) registry.

Background: Studies from high-income countries have shown that women receive less aggressive diagnostics and treatment than men in acute coronary syndromes (ACS), though their short-term mortality does not appear to differ from men. Data on gender differences in ACS presentation, management, and outcomes are sparse in India.

Methods And Results: The Detection and Management of Coronary Heart Disease (DEMAT) Registry collected data from 1,565 suspected ACS patients (334 women; 1,231 men) from ten tertiary care centers throughout India between 2007-2008.

Differential diagnosis of vascular structures in relation to upper ascending aorta: The retro-aortic innominate vein.

The retroaortic course of left innominate vein is a rare entity which can be misinterpreted during echocardiography for other abnormal vascular structures under the arch of aorta. We report the case of a 2 month old infant where the suprasternal window showed 2 vascular structures beneath the aortic arch, one of which was traced to be a retroaortic innominate vein.

Unusual association of aortic valve stenosis with ventricular septal defect and pulmonary atresia: Differentiation from truncus arteriosus with truncal valve stenosis.

Stenosis of systemic semilunar valve in cyanotic congenital heart defects is rare. It can happen in truncus arteriosus with truncal valve stenosis and the very rare anomaly of tetralogy of fallot with aortic valve stenosis. Here we describe a neonate with pulmonary atresia, ventricular septal defect and associated aortic valve stenosis and discuss the points of differentiation from truncus arteriosus.

Percutaneous closure of a moderate to large tubular or elongated patent ductus arteriosus in children younger than 3 years: is the ADO II appropriate?

Protrusion of the Amplatzer duct occluder (ADO) II device into the aortic isthmus or the pulmonary artery causing obstruction and residual flow has been reported, but the same has not been widely studied in small children with a patent ductus arteriosus (PDA) anatomy not considered suitable for closure with the ADO I device. This study aimed to report the safety and efficacy of the ADO II device in children younger than 3 years with a tubular or elongated PDA and to analyze the possible reasons for residual flow in children with such a PDA. In this study, 17 children younger than 3 years (mean age, 10.

Percutaneous transjugular device closure of postoperative residual atrial septal defect.

Percutaneous closure of postoperative malaligned residual atrial septal defect was successfully performed from the transjugular approach under transesophageal echocardiography guidance in a 38-year-old symptomatic woman with patent femoral venous access using the usual hardware. This demonstrates the feasibility of transjugular approach as an alternative to femoral or transhepatic approaches in patients with difficult atrial septal anatomy who are usually referred for surgery.

Septal course of left anterior descending artery from the right aortic sinus in tetralogy of Fallot: a benign anomaly and important lessons learned.

The proximal course of an anomalously arising coronary artery is a decisive factor in the surgical approach for tetralogy of Fallot (TOF). Studies have shown that echocardiography provides a good anatomic definition of the ostium and proximal epicardial course of coronary arteries [1, 2]. This report describes a case of TOF with an atrioventricular canal defect whose preoperative echocardiography showed abnormal origin of the left anterior descending artery (LAD) from right aortic sinus, which was interpreted as crossing the right ventricular outflow tract.

Regression of pulmonary vascular disease after therapy of Abernethy malformation in visceral heterotaxy.

A 1-year-old boy who had left isomerism and corrected transposition of the great arteries (c-TGA) with moderate-sized ventricular septal defect, severe pulmonary artery hypertension (PAH), and pulmonary vascular disease with significant right-to-left shunting received a diagnosis of type 2 Abernethy malformation, which was partly responsible for disproportionate PAH in the child. The malformation was treated by plugging of the portosystemic shunt. Follow-up cardiac catheterization on sildenafil demonstrated significant left-to-right shunting (2.

Crisscross pulmonary artery with double aortic arch: an unusual association.

Anomalies of pulmonary artery origin are rare. Crisscross pulmonary artery origin is a rare benign anomaly characterized by the left pulmonary artery arising superiorly and to the right side of the right pulmonary artery. The condition is usually accompanied by a conotruncal anomaly.

Percutaneous closure of patent ductus arteriosus in children: Immediate and short-term changes in left ventricular systolic and diastolic function.

Objective: To evaluate the effect of percutaneous closure of patent ductus arteriosus (PDA) on left ventricular (LV) systolic and diastolic function in children.

Background: Limited studies are available on alteration in LV hemodynamics, especially diastolic function, after PDA closure.

Methods: Thirty-two consecutive children with isolated PDA treated by trans-catheter closure were studied.

Usefulness of Doppler derived end diastolic flow gradient across the patent ductus arteriosus in selecting coils for ductal occlusion.

Transcatheter closure of patent ductus arteriosus (PDA) with coils is accepted as an alternative to surgical ligation. We evaluated whether flow gradient across PDA, obtained by Doppler echocardiography, can aid in selecting coils for percutaneous ductal occlusion. 79 consecutive patients with PDA, who underwent successful percutaneous coil occlusion were retrospectively reviewed.

Kodamaea ohmeri tricuspid valve endocarditis with right ventricular inflow obstruction in a neonate with structurally normal heart.

The yeast Kodamaea (Pichia) ohmeri is a rare human pathogen with infrequent report of neonatal infection. Native valve endocarditis by Kodamaea ohmeri is extremely rare. The current case report describes a case of fatal nosocomial native valve endocarditis without any structural heart defects in a 40dayold baby.

Trans-catheter closure of atrial septal defect: Balloon sizing or no Balloon sizing - single centre experience.

Background: Selecting the device size using a sizing balloon could oversize the ostium secundum atrial septal defect (OSASD) with floppy margins and at times may lead to complications. Identifying the firm margins using trans-esophageal echocardiography (TEE) and selecting appropriate-sized device optimizes ASD device closure. This retrospective study was undertaken to document the safety and feasibility of device closure without balloon sizing the defect.
