Objective The purpose of this study was to determine the incidence and clinical significance of postoperative delirium (PD) in patients with aortic stenosis undergoing surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). Method Between 2010 and 2013, 427 patients underwent TAVR (n = 168) or SAVR (n = 259) and were screened for PD using the Confusion Assessment Method for the Intensive Care Unit. The incidence of PD in both treatment groups was determined and its association with morbidity and mortality was retrospectively compared. Results PD occurred in 135 patients (32%) with a similar incidence between SAVR (33% [86 out of 259]) and TAVR (29% [49 out of 168]) (P = .40). TAVR by transfemoral approach had the lowest incidence of PD compared with SAVR (18% vs 33%; P = .025) or TAVR when performed by alternative access techniques (18% vs 35%; P = .02). Delirium was associated with longer initial intensive care unit stay (70 vs 27 hours), intensive care unit readmission (10% [14 out of 135] vs 2% [6 out of 292]), and longer hospital stay (8 vs 6 days) (P < .001 for all). PD was associated with increased mortality at 30 days (7% vs 1%; P < .001) and 1 year (21% vs 8%; P < .001). After multivariable adjustment, PD remained associated with increased 1-year mortality (hazard ratio, 3.02; 95% confidence interval, 1.75–5.23; P < .001). There was no interaction between PD and aortic valve replacement approach with respect to 1-year mortality (P = .12). Among propensity-matched patients (n = 170), SAVR-treated patients had a higher incidence of PD than TAVR-treated patients (51% vs 29%; P = .004). Conclusions PD occurs commonly after SAVR and TAVR and is associated with increased morbidity and mortality. Given the high incidence of PD and its associated adverse outcomes, further studies are needed to minimize PD and potentially improve patient outcomes.

Dyslipidemia is the most important atherosclerotic risk factor. Review of population based studies in India shows increasing mean total cholesterol levels. Recent studies have reported that high cholesterol is present in 25-30% of urban and 15-20% rural subjects. This prevalence is lower than high-income countries. The most common dyslipidemia in India are borderline high LDL cholesterol, low HDL cholesterol and high triglycerides. Studies have reported that over a 20-year period total cholesterol, LDL cholesterol and triglyceride levels have increased among urban populations. Case-control studies have reported that there is significant association of coronary events with raised apolipoproteinB, total cholesterol, LDL cholesterol and non-HDL cholesterol and inverse association with high apolipoproteinA and HDL cholesterol. Prevalence of suspected familial hypercholesterolemia in urban subjects varies from 1:125 to 1:450. Only limited studies exist regarding lipid abnormalities in children. There is low awareness, treatment and control of hypercholesterolemia in India.

The learning curves for TA and TAo are distinct but technical proficiency begins to develop by 25 cases and becomes complete by 50 cases for both approaches. Given the relatively low volume of alternative access, achieving technical proficiency may take significant time. However, technical proficiency had no effect on 30-day or 1-year mortality for any access approach.

The transcatheter aortic valve replacement (TAVR) is an established treatment for patients with severe symptomatic aortic stenosis (AS) at prohibitive risk for surgery. It is an alternative treatment to surgical aortic valve replacement in patients with AS at intermediate- and high-surgical risk. Although regulatory authorities extend the indications of TAVR to treat patients at low-surgical risk, the limitations of earlier-generation transcatheter heart valve (THV) systems accelerate the development of improved newer generation of THV systems. Myval™ THV (Meril Life Sciences Pvt. Ltd., Vapi, Gujarat, India) is a newer-generation, balloon-expandable TAVR system with features that facilitate accurate positioning of the bioprosthetic valve and favorable procedural and clinical outcomes. This review summarizes existing preclinical and clinical data on Myval THV for the intervention of symptomatic native AS and lays out the plan for future research program.

Twenty-one percent of all Hodgkin's disease in India was seen in the pediatric age groups at the Tata Memorial Hospital (Bombay, India). From 1975 to 1982, 151 cases of children were reviewed. The youngest presentation was at 3 years in three patients, with a marked male: female ratio of 5.5:1. Twenty-six patients were previously treated before referral while the remaining 125 cases were investigated and treated according to the prevalent protocols in 1975 to 1978 and 1979 to 1982. Clinical staging revealed 54% of patients in stages I and II with symptoms in 20%, and 46% of patients in stages III and IV with symptoms in 67%. Staging laparotomy was performed in 27 patients, with a total changes of staging in 17 children (63%). The mixed cell types (46%) and lymphocytic predominant types (31%) were the most common histologic presentations. Nine percent nodular sclerosis and 9% lymphocytic-depleted varieties were also observed. Five percent of all cases were not classifiable. Minimum adequate treatment was completed in 87 cases. Comparisons were made between the treatments administered to 40 patients during the initial period 1975 to 1978 when individualized treatment was administered, and the later 47 patients during the 1979 to 1982 period, when chemotherapy was the mainstay of treatment with involved field radiation.

Background: Appropriate size selection of transcatheter heart valves (THVs) is fundamental to reduce transcatheter aortic valve implantation (TAVI) related complications, particularly paravalvular aortic regurgitation, new permanent pacemaker implantation, and annular rupture. We sought to investigate the frequency of operator selection of intermediate-size balloon-expandable Myval THVs (Meril Life Sciences Pvt. Ltd., India) for TAVI in a real-world dataset. Methods: In this retrospective survey of patients treated with TAVI using the Myval THV, 20, 23, 26, and 29 mm are conventional-size THVs, 21.5, 24.5 and 27.5 mm are intermediate-size THVs, and 30.5 and 32 mm are extralarge THVs. Operator size selection for implantation was based on multislice computed tomography (MSCT) derived aortic-root dimensions. Results: A total of 1115 patients underwent Myval THV implantation in 27 countries worldwide. The Myval intermediate-size THVs were used in 468 (42.0%) patients. MSCT data were available in 562 patients. There was no statistical difference between the Intermediate/Upsized and Appropriately sized groups or Intermediate/Downsized and Appropriately sized groups in terms of different variables measured with MSCT except for annular dimensions and degree of calcification. Conclusions: Intermediate-size Myval balloon-expandable THVs are used in nearly half of all cases in contemporary real-world TAVI practice, addressing the unmet need of TAVI operators for a more calibrated THV choice. Our hypothesis should be tested in randomized prospective studies currently initiated in Europe, including clinical outcomes of patients treated with both conventional-and intermediate-size THVs.
