Adult Partial Anomalous Pulmonary Venous Connection: Case Reports (Including a Case of Scimitar Syndrome).

Partial anomalous pulmonary venous connection (PAPVC) is a congenital heart defect in which one or more pulmonary veins drain abnormally into the systemic venous circulation, leading to the development of pulmonary arterial hypertension. It can be supracardiac type, draining into the superior vena cava or right atrium (also called cardiac type) and infracardiac type with drainage into the inferior vena cava (IVC). We present two cases-supracardiac and infracardiac types of PAPVC in this case report.

How to perform a percutaneous coronary intervention, when no conventional arterial access site is available: A case report.

Coronary artery disease is one of the leading causes of mortality in the world. The presence of concomitant peripheral artery disease increases the risks of cardiovascular events along with limiting the arterial access for coronary intervention. Invasive management of such cases includes either alternate site access or combined peripheral and coronary revascularization. We hereby report a patient of the infrarenal abdominal aorta and bilateral subclavian arterial occlusion, who presented with acute coronary syndrome. To perform the percutaneous coronary intervention, we first performed the endovascular stenting of occluded aortoiliac disease, followed by stenting of the right coronary artery. We had discussed the limitation of arterial access to perform PCI in such a situation.

Changing spectrum of infective endocarditis in India: An 11-year experience from an academic hospital in North India.

OBJECTIVE: Several studies have demonstrated a shift in the spectrum of infective endocarditis (IE) in the developed world. We aimed to investigate whether demographic and microbiologic characteristics of IE have changed in India. DESIGN: A retrospective analysis of patients with in north India between 2010 and 2020. METHODS: The clinical and laboratory profiles of 199 IE admitted to an academic hospital patients who met the modified Duke criteria for definite IE were analysed. RESULTS: The mean age was 34 years, and 84% were males. The main predisposing conditions were injection drug use (IDU) (n = 71, 35.7%), congenital heart disease (n = 46, 21.6%), rheumatic heart disease (n = 25, 12.5%), and prosthetic device (n = 19, 9.5%). 17.1% of patients developed IE without identified predispositions. Among 64.3% culture-positive cases, the most prevalent causative pathogens were Staphylococcus aureus (46.1%), viridans streptococci (7.0%), enterococci (6.0%), coagulase-negative staphylococci (5.5%), gram negative bacilli (5.5%), polymicrobial (5.5%), and Candida (1.0%). The tricuspid (30.3%), mitral (25.6%), and aortic (21.6%) valves were the most common sites of infection, and 60.3% had large vegetations (>10 mm). Systemic embolization occurred in 55.3% of patients at presentation. Cardiac surgery was required for 13.1%. In-hospital mortality was 17.1% and was associated with prosthetic devices (p-value, 0.001), baseline leucocytosis (p-value, 0.036) or acute kidney injury (p-value, 0.001), and a microbial etiology of gram negative bacilli or enterococci (p-value, 0.005). CONCLUSION: IDU is now the most important predisposition for IE in India, and S. aureus has become the leading cause of native valve endocarditis with or without IDU.

One-year outcomes of novel BioMime Morph tapered stent in long and multiple coronary artery lesions.

OBJECTIVE: Even with the immense progress achieved in the field of percutaneous coronary interventions (PCIs), treatment of diffuse long atherosclerotic coronary artery disease continues to remain a challenge for durable outcomes. The downstream reduction in diameter along the lesion length of a coronary artery may compel the cardiologist to use either 2 overlapping stents of different diameters or a single long stent leading to stent-vessel mismatch at the edges. Recently, Meril Life Sciences Pvt. Ltd., India, has introduced a long-tapered sirolimus-eluting stent (SES) system, BioMime Morph, which conforms to the normal tapered geometry of coronary arteries along with adequate lesion coverage. In this study, we aimed to provide real world experience regarding the safety and efficacy of the BioMime Morph SES over a follow-up of one year. METHODS: This was a single center, retrospective study involving 172 participants who underwent PCI with the BioMime Morph SES. Mean length of the target lesion was 34.4±10.4 mm, and mean stent length was 53.2±8.7 mm. The most frequent revascularized vessel was the left anterior descending artery (LAD) in 97 lesions (54.4%). RESULTS: Major adverse cardiac events (MACE) (defined as a composite of target vessel myocardial infarction, target lesion revascularization, and death due to a cardiac cause) at 1, 6, and 12 months were seen in 4 (2.3%), 7 (4.0%), and 8 (4.7%) patients, respectively. Overall, 5 cardiac deaths and 2 definite stent thrombosis were observed in the study. CONCLUSION: The study suggests that the novel BioMime Morph SES is an effective and a safe option for PCI in the treatment of long diffuse atherosclerotic lesions.

Epidemiological and clinical profile, management and outcomes of young patients (≤40 years) with acute coronary syndrome: A single tertiary care center study.

OBJECTIVE: To study the epidemiological and clinical profile, angiographic patterns, reasons for the delay in presentation, management, and outcomes of the acute coronary syndrome (ACS) in young patients (≤40yrs) presenting to a tertiary care hospital in North India. METHODS: We included a total of 182 patients aged ≤40 years and presenting with ACS to the cardiology critical care unit of our department from January 2018 to July 2019. RESULTS: The mean age of the study population was 35.5 ± 4.7years. 96.2% were males. Risk factors prevalent were smoking (56%), hypertension (29.7%), family history of premature coronary artery disease (18.2%), and diabetes (15.9%). The median time to first medical contact and revascularization was 300 (10-43200) minutes and 2880 (75-68400) minutes, respectively. ST-elevation ACS (STE-ACS) accounted for 82% and Non-ST-elevation ACS (NSTE-ACS) accounted for 18% of cases. Thrombolysis was done in 51.7% of the cases. Coronary angiography was done in 91.7% and percutaneous coronary intervention (PCI) in 52.2% (95/182) of the total cases. Coronary artery bypass surgery (CABG) was done in 2 patients (1.1%). Among those who underwent coronary angiography, single-vessel disease (SVD) was seen in 53% of the cases. There were no deaths in hospital, and only one patient died during the 30 days follow up. CONCLUSIONS: STE-ACS was the most common presentation of ACS in the young population. Smoking was the most common risk factor. The majority of the patients had single-vessel disease, and there was a significant delay in first medical contact and revascularization.

Prevalence and Pattern of Congenital Coronary Artery Anomalies in Patients Undergoing Coronary Angiography at a Tertiary Care Hospital of Northern India.

OBJECTIVES: To evaluate the prevalence and pattern of congenital coronary artery anomalies (CAAs) in the adult population undergoing catheter coronary angiography. METHODS: The coronary angiograms done between October 2015 and September 2020 were reviewed for the presence of coronary anomalies based upon Angelini's classification. The medical record of patients with anomalies was reviewed for symptomatology and indication of angiography. RESULTS: CAAs were found in 129 (87 males and 42 females) of 6,258 patients giving a prevalence of 2.06%. The mean age was 57.8 ± 11.8 (range 32-81) years. Among these, the anomalous origin and course of the coronaries were the most common anomaly seen in 81 (1.29%) patients, followed by intrinsic anomalies of the coronary arterial system in 44 (0.7%) patients and anomalies of coronary termination and anomalous anastomotic vessels in 2 (0.03%) patients each. Overall, the absence of the left main trunk with a separate origin of the left anterior descending (LAD) and the circumflex artery was the commonest anomaly seen in 46 (0.74%) patients, followed by dual LAD in 35 (0.56%) patients. The anomalous origin of the right coronary artery (RCA) from the left sinus was seen in 14 patients (0.22%) and that of the circumflex artery from the right sinus or right coronary artery was seen in 11 patients (0.17%). The origin of the left main and RCA from ascending aorta was found in eight (0.13%) patients. One (0.02%) patient had a single coronary artery, and another one (0.02%) had all the three coronary arteries arising from the right sinus; however, with separate ostia. The split RCA was seen in nine (0.14%) patients and there were two (0.03%) patients each of coronary artery fistulae, and of anomalous anastomotic vessels. CONCLUSIONS: The prevalence of congenital coronary anomalies in this study was 2.06%. The commonest anomaly was that of origin and courses of the vessels, however, the pattern of anomalies is different from previous studies.

Epidemiological profile, management and outcomes of patients with acute coronary syndrome: Single centre experience from a tertiary care hospital in North India.

BACKGROUND: Cardiovascular disease is the leading cause of death in India. Our aim is to study the clinical, epidemiological profile and in-hospital outcomes of patients presenting with acute coronary syndrome. METHODS: We did a prospective single center observational study of the 1203 patients presenting with ACS to a tertiary referral center in North India over a period of one year (July 2018-June 2019). RESULTS: The mean age of study population was 58.4 ± 12.5 years. STEMI and NSTE-ACS accounted for 69.9% and 31.1% respectively. 62.1% of our patients were from rural background. The median time to hospital admission was 600 min for STEMI patients, thrombolysis was performed in 52% of cases. Cardiogenic shock at presentation was noted in 18%. Coronary angiography and percutaneous coronary intervention were done in 1062 (88.3%) and 733 (60.9%) patients respectively. The overall in-hospital mortality was 7.6%. STEMI patients had higher mortality than NSTE-ACS (8.9% vs 4.5% p < 0.001). Female gender (OR-3.306 C.I. 1.87-5.845), severe MR (OR-4.65, C.I.-1.187-18.18), acute kidney injury (AKI) at admission (OR-5.15, C.I.-2.5-10.63), higher Killip class (class III/IV) (OR-3.378,C.I.-1.292-8.849), AF (OR-3.25, C.I.-1,18-8.92), complete heart block (CHB) (OR-4.44,C.I.-2.09-9.43) and right bundle branch block (RBBB) (OR-2.86, C.I.-1.2-6.8) were significant predictors of in hospital mortality. CONCLUSIONS: Our study represents the predominance of STEMI as the initial ACS presentation with a considerable delay in first medical contact and higher prevalence of cardiogenic shock (CS). STEMI patients had higher mortality. Female sex, severe MR, AKI, higher Killips class, AF, CHB, RBBB being predictors of high in-hospital mortality in ACS patients.

Correlation of Vitamin D Deficiency With Severity of Chronic Heart Failure as Assessed by Functional Class and N-Terminal Pro-Brain Natriuretic Peptide Levels.

Introduction Chronic heart failure (CHF) is a major cause of mortality and morbidity in spite of tremendous advances in medical therapies. Vitamin D deficiency has been increasingly recognised in heart failure and its therapeutic as well as prognostic implications are debated. This study was carried out to examine the relationship of Vitamin D levels with severity of heart failure as assessed by NYHA functional class and serum N-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels in vitamin D deficient patients with CHF. Methodology and results In this cross-sectional analysis, 119 patients of symptomatic CHF presenting to the outpatient/inpatient department of cardiology in a tertiary care institute in North India were screened. Patients were categorised according to their functional class as New York Heart Association (NYHA) class II, III, IV and their serum levels of vitamin D and NT-pro-BNP were measured. Out of 119 patients, 107 (90%) were found to have low vitamin D levels which were classified as insufficient (20-30 ng/ml) (n=25, 23%) or deficient (<20 ng/ml) (n=82,77%). The mean NT-pro-BNP levels increased significantly across functional class as 3783±6132 pg/ml, 7866±4383 pg/ml, 21115±11905 pg/ml in NYHA class II, III and IV respectively (p=0.000). The respective mean serum Vitamin D3 levels of 11.6±5.8ng/ml, 12.2±7.9 ng/ml, 14.4±8.9 ng/ml were not significantly different between classes (p=0.234). We found no correlation between serum NT-pro-BNP and serum vitamin D levels in the study cohort across various NYHA classes. In multivariate regression model, after adjusting for various co-variates, vitamin D levels were not significantly associated with NT-pro-BNP or functional class in patients with CHF. Conclusion Patients with CHF have a high prevalence (90%) of vitamin D deficiency. Although NT-pro-BNP levels increase significantly, vitamin D levels do not vary significantly with worsening NYHA classes. Further, no consistent significant correlation of vitamin D deficiency with NT-pro-BNP across different NYHA classes was observed. Thus, low levels of vitamin D didn't predict the severity and prognosis of patients with heart failure. .

Retroperitoneal iliac conduits as an alternative access site for endovascular aortic repair: a tertiary care center experience.

Background: Retroperitoneal open iliac conduits (ROIC) are used in patients with hostile iliac anatomy undergoing endovascular aortic repair (EVAR). Objectives: We hereby report our experience of ROIC in patients subjected to EVAR. Methods: This was a retrospective evaluation of 8 patients out of a total of 75 patients (11%) who underwent EVAR in the last 10 years. Pre-procedure computed tomography angiography was used to assess the dimensions of iliac and femoral arteries. Patients who had small arterial dimensions (i.e. smaller than the recommended access size for the aortic endograft device) were subjected to ROIC. Results: The mean age of the 3 males and 5 females studied was 45.7 ± 15.2 years. The indication for ROIC was the small caliber ilio-femoral access site in 7 patients and atherosclerotic disease in 1 patient. All external grafts were anastomosed to the right common iliac artery except one which was anastomosed to the aortic bifurcation site because of a small common iliac artery. The procedural success rate was 100%. Local access site complications included infection (n=1), retroperitoneal hematoma (n=1), and need for blood transfusion (n=3). The median post-intervention hospital stay was 10 days. All patients had favorable long-term outcomes at a median follow-up of 18 months. Conclusions: Female patients require ROIC during EVAR more frequently. Adjunctive use of iliac conduit for EVAR was associated with favorable perioperative and short-term outcomes.

Contexto: Os condutos ilíacos abertos retroperitoneais são utilizados em pacientes submetidos a reparo endovascular de aneurisma (REVA) com anatomia ilíaca hostil. Objetivos: Relatamos a nossa experiência com os condutos ilíacos em pacientes submetidos a REVA. Métodos: Trata-se de uma avaliação retrospectiva de oito pacientes, de um total de 75 (11%), os quais foram submetidos a REVA nos últimos 10 anos. Foi realizada angiotomografia computadorizada antes do procedimento para avaliar as dimensões das artérias ilíaca e femoral. Os pacientes com dimensões arteriais menores, abaixo do tamanho de acesso recomendado para o dispositivo de endoprótese aórtica, foram submetidos a condutos ilíacos. Resultados: A média de idade dos participantes foi de 45,7±15,2 anos, sendo três do sexo masculino e cinco do sexo feminino. As indicações para condutos ilíacos foram local de acesso ilíaco femoral de pequeno calibre, para sete pacientes, e doença aterosclerótica, para um paciente. Todas as próteses externas foram anastomosadas na artéria ilíaca comum direita, com exceção de uma, que foi anastomosada no local da bifurcação aórtica por apresentar artéria ilíaca comum menor. A taxa de sucesso do procedimento foi de 100%. As complicações no local de acesso incluíram infecção (n = 1), hematoma retroperitoneal (n = 1) e necessidade de transfusão de sangue (n = 3). O tempo mediano de internação hospitalar pós-intervenção foi de 10 dias. Todos os pacientes apresentaram desfechos de longo prazo favoráveis no seguimento mediano de 18 meses. Conclusões: As pacientes do sexo feminino necessitaram de condutos ilíacos durante REVA com maior frequência. O uso adjuvante de condutos ilíacos com REVA foi associado a desfechos perioperatórios e de curto prazo favoráveis.

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 0.066%. Percutaneous coronary intervention (PCI) of coronary artery disease (CAD) in these patients is technically challenging. METHODS: We retrospective analyzed the cardiac catheterization procedures of last 15 years and found 12 cases of SCA (incidence 0.084%). To determine the course of anomalous coronaries, angiographic "dot and eye" method and computed tomography (CT) were used. The course of the SCA was classified as per the modified Lipton criteria. PCI was performed as per the standard protocol for a significant epicardial coronary artery stenosis. RESULTS: Out of total 12 patients of SCA, 9 patients had PCI of significant CAD. The mean age of 9 PCI patients was 63.8 ± 8.2 years (5 males, 4 females). The origin of the SCA was from the right sinus of Valsalva in 6 cases and from left sinus of Valsalva in 3 cases. Eleven successful PCI procedures were performed, which included PCI of left main, coronary bifurcation lesion, chronic total occlusion, and multi-vessel disease. Four patients had intravascular imaging and 3 patients had rotablation of calcified lesions. CONCLUSION: PCI of SCA is technically challenging, which requires considerable expertise and experience. An appropriate selection of hardware along with technical expertise can make the procedure simpler with optimal end results.

Case of calcific tricuspid and pulmonary valve stenosis.

Isolated right-sided valvular disease is a much less recognised entity when compared with left-sided valvular heart disease. Almost all the cases of combined pulmonary valve with tricuspid valve involvement are a consequence of underlying carcinoid heart disease. Moreover, severe calcification of tricuspid valve is an extremely unusual finding. We report a case of a severe calcific tricuspid valve stenosis along with severe pulmonary valve stenosis where the exact aetiology could not be established. On reviewing the literature, we did not find any reports describing such a morphology.

Comparison of isolated venous approach with the standard approach in children undergoing patent ductus arteriosus device closure.

BACKGROUND: Transcatheter device closure is a safe procedure recommended in children with patent ductus arteriosus (PDA). While the standard procedure uses arterial and venous femoral access, it poses risk of vascular complications especially in young infants. Isolated venous approach has been tried in a few studies and was found to be non-inferior to the standard technique. In this prospective observational study, we have compared the two vascular approaches of PDA device closure in pediatric patients and have also studied the feasibility of this approach in young children with weight < 6 kg. RESULTS: PDA device occlusion was performed with either one of the approaches-venous alone (group I) or standard approach (group II) in a total of 135 children enrolled prospectively. The baseline data, procedural outcomes, vascular complications, and radiation dose were compared between the two groups. Fifty-two and 83 children were included in group I and group II, respectively. A total of 22 children (16%) (13 in group I; 9 in group II) had weight < 6 kg. In group II, 6 children (7.2%) had vascular site complications treated with heparin infusion with two children requiring thrombolysis. Another child in group II developed intravascular hemolysis following residual shunt, requiring surgical device retrieval and closure. No significant differences were observed in mean fluoroscopic time (p = 0.472) and air kerma between the two groups (p = 0.989). CONCLUSION: Transcatheter PDA device closure without arterial access is a feasible and safe option in children including young infants. This technique avoids the risk of vascular complications although requires careful case selection.

Use of BioMime Morph stent in treating left main triple vessel disease: a case report.

BACKGROUND: Diffuse long coronary lesions require long overlapping stents which produce less than optimal long-term results. Sizing of long stents becomes difficult owing to tapering of coronaries and overlapping with excessive metal which makes restenosis a nagging problem on long-term follow-up. The optimal stent sizing becomes even more important when left main (LM) needs to be treated along with left ascending artery (LAD) or left circumflex artery (Lcx). The chronic total occlusions (CTO) represent other complex diffuse coronary lesions which not only require higher expertise and better hardware but also usually long lengths of overlapping stents. The long-tapered sirolimus-eluting stent system (BioMime Morph) has been successfully used in long diffuse lesions in individual coronaries including CTO but the use of the same in LM-LAD/LM-Lcx diffuse lesions has not been explored well where its tapered design can really be favourable. CASE PRESENTATION: We here present a case of a 51-year-old hypertensive male presented with NSTEMI and angiography showing left main triple vessel disease with CTO of right coronary artery (RCA). We successfully stented the LM-LAD and RCA (staged) using a long-tapered BioMime Morph system. IVUS was used for optimising the LM-LAD stent. At 6 months follow-up, the patient was doing well on double anti-platelets. CONCLUSION: Complex coronary disease, involving the left main and LAD diffusely and CTO of RCA, can be well managed by using a single long-tapered stents thereby avoiding multiple stenting strategy. The stents with decremental diameter will provide better adaptation to the vessel size and their natural tapering. The usage of intravascular imaging helps in better optimisation of stents.

Congenital right coronary artery aneurysm with fistula to right ventricle associated with isolated pulmonary valvular stenosis.

Congenital aneurysmal dilatation of coronary artery with coronary cameral fistula is rare in childhood. We report an even rarer association of congenital right coronary artery aneurysm and right coronary artery to right ventricle fistula with bicuspid pulmonary valve stenosis and an intact ventricular septum in a 3-year-old child.

Role of Rifampin in Reducing Inflammation and Neuronal Damage in Childhood Bacterial Meningitis: A Pilot Randomized Controlled Trial.

BACKGROUND: Treatment of acute bacterial meningitis in children with bactericidal antibiotics causes cell wall lysis and a surge in inflammatory cascade, which in turn contributes to neuronal damage and morbidity. Pretreatment with a nonbacteriolytic antibiotic, such as rifampin, has been shown to attenuate the inflammatory response in experimental models of bacterial meningitis. In a pilot study, in children with bacterial meningitis, we have studied markers of inflammatory response and neuronal damage in 2 groups of children with bacterial meningitis; one group received rifampin pretreatment with ceftriaxone and the other group received ceftriaxone alone. PATIENTS AND METHODS: Forty children with bacterial meningitis, who were 3 months to 12 years of age, were randomly assigned to receive either a single dose rifampin (20 mg/kg) 30 minutes before ceftriaxone or ceftriaxone alone was given. The primary outcome variables were cerebrospinal fluid (CSF) concentrations of tumor necrosis factor alpha (TNFα), S100B and neuron-specific enolase on day 1 and day 5, and secondary outcome variables were the values of TNFα and interleukin 6 in serum on day 1 and day 5; hearing and neurologic sequelae at 3 months after recovery from the illness. RESULTS: Children in rifampin pretreatment group had significantly lower CSF TNFα concentrations [median (interquartile range [IQR]): 15.5 (7.2-22.0) vs. 53.0 (9.0-87.5) pg/mL, P = 0.019] and S100B [median (IQR): 145.0 (54.7-450.0) vs. 447.5 (221.0-804.6) pg/mL, P = 0.033] on day 1 and S100B [median (IQR): 109.7 (64.0-287.0) vs. 322 (106.7-578.0) pg/mL, P = 0.048] and neuron-specific enolase [median (IQR): 8.6 (5-14.75) vs. 18.2 (7.0-28.75) ng/mL, P = 0.035] on day 5 when compared with ceftriaxone alone group. The rifampin-treated group also had reduced morbidity and neurologic sequelae; however, these were not statistically significant. CONCLUSIONS: Pretreatment with single dose rifampin 30 minutes before ceftriaxone administration reduced the CSF concentrations of markers of inflammation and neuronal damage in children with bacterial meningitis.
