RESUMO
OBJECTIVES: Radiological intervention (RI) is the preferred treatment in children with Budd-Chiari syndrome (BCS). We studied the comparative long-term outcome of BCS children, with and without RI and utility of liver and splenic stiffness measurement (LSM, SSM) by 2-dimensional shear wave elastography (2D-SWE) in assessing response. METHODS: Sixty children (40 boys, median age 10.5 [6.5-15.25] years) with BCS (29 newly diagnosed, 31 follow-up) were evaluated. LSM and SSM by 2D-SWE and vascular patency were monitored pre- and postprocedure (≥ 6 months postprocedure) in those undergoing RI. Medical therapy without anticoagulation and monitoring was done in subjects without RI. The RI and no-RI groups were compared. RESULTS: Ascites (54,90%), hepatomegaly (56,93%) and prominent abdominal-veins (42,70%), were the commonest features. The majority (46,78%) had isolated hepatic vein block. 44 (73%) cases underwent RI, while 16 (27%) were managed conservatively. Both groups were similar at baseline. Post-RI subjects showed significant improvement in clinical findings, liver functions and portal hypertension. LSM [33 (32-34.5) to 19.2 (18-20.67) kPa] and SSM [54.5 (52.3-57.6) to 28.9 (27.6-30.25) kPa] showed a significant decline from baseline value over a follow-up of 12 (6-13) months. Gradual reduction occurred in the LSM and SSM over 1-5 years, with near-normal LSM [10.2 (9.2-11.5) kPa] and SSM [22.3 (20.5-24.3) kPa] values in patients (n-16) with > 5 years follow-up. Patients without RI showed worsening in LSM and SSM. Hepatopulmonary syndrome and hepatocellular carcinoma developed in 4 (8%) and 1 (1.7%) cases respectively. CONCLUSION: RI leads to clinical recovery and reduction with near normalization of LSM and SSM over long-term follow-up in children with BCS. 2D-SWE is a promising tool to monitor outcomes.

AIM: Analyze antibiotic susceptibility in the Endophthalmitis Management Study (EMS) and compare it with the current intravitreal antibiotic practice trend of members of the Vitreoretinal Society of India (VRSI) practicing in India. METHODS: The microbiology work-up of undiluted vitreous included microscopy, culture-susceptibility, polymerase chain reaction (PCR), and next-generation sequencing (NGS). VRSI members were invited to the survey. The EMS conventional culture-susceptibility (PCR and NGS excluded) results were compared vis-a-vis gram-positive cocci (GPC), gram-negative bacilli (GNB), and less commonly used antibiotics with the current recommended intravitreal antibiotics. p < 0.05 was considered significant. RESULTS: Culture and positivity (culture + PCR/NGS) positivity was 28.8% and 56.1%, respectively. GPC was most susceptible to cefazolin, linezolid, and vancomycin; GNB was most susceptible to amikacin, ceftazidime, colistin, and imipenem. There was no susceptibility difference between cefazolin and vancomycin (p = 0.999) and between ceftazidime and imipenem (p = 1.0). Colistin was superior to ceftazidime (p = 0.047) against GNB. The GNB resistant to amikacin (n = 14) were equally susceptible to ceftazidime and colistin; resistant to ceftazidime (n = 16) were susceptible to colistin; and resistant to colistin (n = 7) were susceptible to ceftazidime. The preference of VRSI members (n = 231) practicing in India was a vancomycin-ceftazidime combination (82%), vancomycin for GPC (94%), ceftazidime for GNB (61%), and voriconazole for fungi (74%). CONCLUSION: In EMS, GPC had good susceptibility to vancomycin; GNB had good susceptibility to ceftazidime and colistin. Given the lower resistance of colistin, a vancomycin-colistin combination could be an alternative empiric treatment in post-cataract endophthalmitis in India.

Heart failure (HF) is a global health concern that is prevalent in India as well. HF is reported at a younger age in Indian patients with comorbidity of type 2 diabetes (T2DM) in approximately 50% of patients. Sodium-glucose cotransporter-2 inhibitors (SGLT2i), originally approved for T2DM, are new guideline-recommended and approved treatment strategies for HF. Extensive evidence highlights that SGLT2i exhibits profound cardiovascular (CV) benefits beyond glycemic control. SGLT2i, in conjunction with other guideline-directed medical therapies (GMDT), has additive effects in improving heart function and reducing adverse HF outcomes. The benefits of SGLT2i are across a spectrum of patients, with and without diabetes, suggesting their potential place in broader HF populations irrespective of ejection fraction (EF). This consensus builds on the updated evidence of the efficacy and safety of SGLT2i in HF and recommends its place in therapy with a focus on Indian patients with HF.

Chronic kidney disease (CKD) is a major contributor to morbidity and mortality in India. CKD often coexists with heart failure (HF), diabetes, and hypertension. All these comorbidities are risk factors for renal impairment. HF and CKD are pathophysiologically intertwined, and the deterioration of one can worsen the prognosis of the other. There is a need for safe renal pharmacological therapies that target both CKD and HF and are also useful in hypertension and diabetes. Neurohormonal activation achieved through the activation of the sympathetic nervous system (SNS), the renin-angiotensin-aldosterone system (RAAS), and the natriuretic peptide system (NPS) is fundamental in the pathogenesis and progression of CKD and HF. Angiotensin receptor neprilysin inhibitor (ARNi), sodium-glucose cotransporter 2 inhibitors (SGLT-2i), and selective ß1-blocker (B1B) bisoprolol suppress this neurohormonal activation. They also have many other cardiorenal benefits across a wide range of CKD patients with or without concomitant HF, diabetes, or hypertension. This consensus statement from India explores the place of ARNi, SGLT-2i, and bisoprolol in the management of CKD patients with or without HF and other comorbidities.

The rapidly increasing burden of hypertension is responsible for premature deaths from cardiovascular disease (CVD), renal disease, and stroke, with a tremendous public health and financial burden. Hypertension detection, treatment, and control vary worldwide; it is still low, particularly in low- and middle-income countries (LMICs). High blood pressure (BP) and CVD risk have a strong, linear, and independent association. They contribute to alarming numbers of all-cause and CVD deaths. A major culprit for increased hypertension is sympathetic activity, and further complications of hypertension are heart failure, ischemic heart disease (IHD), stroke, and renal failure. Now, antihypertensive interventions have emerged as a global public health priority to reduce BP-related morbidity and mortality. Calcium channel blockers (CCB) are highly effective vasodilators. and the most common drugs used for managing hypertension and CVD. Cilnidipine, with both L- and N-type calcium channel blocking activity, is a promising 4th generation CCB. It causes vasodilation via L-type calcium channel blockade and inhibits the sympathetic nervous system (SNS) via N-type calcium channel blockade. Cilnidipine, which acts as a dual L/N-type CCB, is linked to a reduced occurrence of pedal edema compared to amlodipine, which solely blocks L-type calcium channels. The antihypertensive properties of cilnidipine are very substantial, with low BP variability and long-acting properties. It is beneficial for hypertensive patients to deal with morning hypertension and for patients with abnormal nocturnal BP due to exaggerated sympathetic nerve activation. Besides its BP-lowering effect, it also exhibits organ protection via sympathetic nerve inhibition and renin-angiotensin-aldosterone system inhibition; it controls heart rate and proteinuria. Reno-protective, neuroprotective, and cardioprotective effects of cilnidipine have been well-documented and demonstrated.

BACKGROUND: Anodyspareunia may be an adverse outcome of prostate cancer (PCa) treatment for gay, bisexual, and other men who have sex with men (GBM). AIM: The aims of this study were to (1) describe the clinical symptoms of painful receptive anal intercourse (RAI) in GBM following PCa treatment, (2) estimate the prevalence of anodyspareunia, and (3) identify clinical and psychosocial correlates. METHODS: This was a secondary analysis of baseline and 24-month follow-up data from the Restore-2 randomized clinical trial of 401 GBM treated for PCa. The analytic sample included only those participants who attempted RAI during or since their PCa treatment (N = 195). OUTCOMES: Anodyspareunia was operationalized as moderate to severe pain during RAI for ≥6 months that resulted in mild to severe distress. Additional quality-of-life outcomes included the Expanded Prostate Cancer Index Composite (bowel function and bother subscales), the Brief Symptom Inventory-18, and the Functional Assessment of Cancer Therapy-Prostate. RESULTS: Overall 82 (42.1%) participants reported pain during RAI since completing PCa treatment. Of these, 45.1% experienced painful RAI sometimes or frequently, and 63.0% indicated that the pain was persistent. The pain at its worst was moderate to very severe for 79.0%. The experience of pain was at least mildly distressing for 63.5%. Painful RAI worsened for a third (33.4%) of participants after completing PCa treatment. Of the 82 GBM, 15.4% were classified as meeting criteria for anodyspareunia. Antecedents of anodyspareunia included a lifelong history of painful RAI and bowel dysfunction following PCa treatment. Those reporting symptoms of anodyspareunia were more likely to avoid RAI due to pain (adjusted odds ratio, 4.37), which was negatively associated with sexual satisfaction (mean difference, -2.77) and self-esteem (mean difference, -3.33). The model explained 37.2% of the variance in overall quality of life. CLINICAL IMPLICATIONS: Culturally responsive PCa care should include the assessment of anodyspareunia among GBM and explore treatment options. STRENGTHS AND LIMITATIONS: This is the largest study to date focused on anodyspareunia among GBM treated for PCa. Anodyspareunia was assessed with multiple items characterizing the intensity, duration, and distress related to painful RAI. The external validity of the findings is limited by the nonprobability sample. Furthermore, the cause-and-effect relationships between the reported associations cannot be established by the research design. CONCLUSIONS: Anodyspareunia should be considered a sexual dysfunction in GBM and investigated as an adverse outcome of PCa treatment.

BACKGROUND: Pheochromocytoma and paraganglioma (PPGL) are catecholamine producing tumors of chromaffin cell origin, known to cause varied cardiovascular manifestations from hypertension to myocardial infarction. This study sought to objectively evaluate the cardiac changes in PPGL patients and their reversal following curative surgery. METHODS: The PheoCard study was registered in ClinicalTrials.gov (NCT05082311) and involved 35 consecutive PPGL patients managed as per standard protocol involving alpha blockade followed by curative surgery. They underwent detailed cardiac evaluation using 2D-echocardiography and speckle tracking echocardiography at the time of diagnosis, 7-10 days after alpha blockade, and at 7 days, 3 months, and 6 months after surgical removal. Age- and gender-matched essential hypertensives and healthy individuals (10 in each group) served as two control groups. RESULTS: Patients with PPGLs had significantly higher mean blood pressure, left ventricle end-diastolic dimension and volume (LVEDD, LVEDV), left ventricle end-systolic volume (LVESV), septal wall thickness, LV hypertrophy, lower mean LV ejection fraction (LVEF), early diastolic mitral annular velocity (E/A), decreased amplitude of LV longitudinal strain, and increased circumferential strain (p < 0.001) when compared with the control groups at baseline. After alpha blockade, there was marked reduction in the mean LVEDD, LVEDV, LVESV, and normalization of E/A ratio (p < 0.001) in the PPGL patients. Following curative surgery (normalization of fractionated urinary metanephrines at 7-10 days post-operatively), there was early improvement in all echocardiographic parameters and it continued to improve even at 6 months after surgery. There was marked improvement in the global longitudinal strain as seen on serial speckle tracking echocardiography with recovery of most of the segments of LV depicting the reversal of subclinical endocardial dysfunction (p < 0.001). CONCLUSION: PPGL patients despite normal systolic function have subclinical LV diastolic dysfunction which is reversed after curative surgery. TRIAL REGISTRATION: ClinicalTrials.gov NCT05082311.

;Heart failure (HF) is a huge global public health task due to morbidity, mortality, disturbed quality of life, and major economic burden. It is an area of active research and newer treatment strategies are evolving. Recently angiotensin receptor-neprilysin inhibitor (ARNI), a class of drugs (the first agent in this class, Sacubitril-Valsartan), reduces cardiovascular mortality and morbidity in chronic HF patients with reduced left ventricular ejection fraction (LVEF). Positive therapeutic effects have led to a decrease in cardiovascular mortality and HF hospitalizations (HFH), with a favorable safety profile, and have been documented in several clinical studies with an unquestionable survival benefit with ARNI, Sacubitril-Valsartan. This consensus statement of the Indian group of experts in cardiology, nephrology, and diabetes provides a comprehensive review of the power and promise of ARNI in HF management and an evidence-based appraisal of the use of ARNI as an essential treatment strategy for HF patients in clinical practice. Consensus in this review favors an early utility of Sacubitril-Valsartan in patients with HF with reduced EF (HFrEF), regardless of the previous therapy being given. A lower rate of hospitalizations for HF with Sacubitril-Valsartan in HF patients with preserved EF who are phenotypically heterogeneous suggests possible benefits of ARNI in patients having 40-50% of LVEF, frequent subtle systolic dysfunction, and higher hospitalization risk.

Iron deficiency (ID) with or without anemia is frequently observed in patients with heart failure (HF). Uncorrected ID is associated with higher hospitalization and mortality in patients with acute HF (AHF) and chronic HF (CHF). Hence, in addition to chronic renal insufficiency, anemia, and diabetes, ID appears as a novel comorbidity and a treatment target of CHF. Intravenous (IV) ferric carboxymaltose (FCM) reduces the hospitalization risk due to HF worsening and improves functional capacity and quality of life (QOL) in HF patients. The current consensus document provides criteria, an expert opinion on the diagnosis of ID in HF, patient profiles for IV FCM, and correct administration and monitoring of such patients.

Adverse cardiac remodeling refers to progressive structural and functional modifications in the heart because of increased wall stress in the myocardium, loss of viable myocardium, and neurohormonal stimulation. The guideline-directed medical therapy for Heart failure (HF) includes Angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan), ß-blockers, sodium-glucose co-transporter 2 (SGLT2) inhibitors, and mineralocorticoid receptor antagonists (MRA). ARNI is under-prescribed in India despite its attractive safety and efficacy profile. Therefore, the consensus discusses objectives and topics related to ARNI in the management of cardiac remodeling, and experts shared their views on the early timely intervention of effective dosage of ARNI to improve the diagnosis and enhance mortality and morbidity benefits in cardiac reverse remodeling (CRR).

In India, heart failure (HF) is an important health concern affecting younger age groups than the western population. A limited number of Indian patients receive guideline-directed medical therapy (GDMT). Selective ß-1 blockers (BB) are one of the GDMTs in HF and play an important role by decreasing the sympathetic overdrive. The BB reduces heart rate (HR) reverse the adverse cardiac (both ventricular and atrial), vascular, and renovascular remodeling seen in HF. Bisoprolol, a ß-1 blocker, has several advantages and can be used across a wide spectrum of HF presentations and in patients with HF and comorbid conditions such as coronary artery disease (CAD), atrial fibrillation (AF), post-myocardial infarction (MI), uncontrolled diabetes, uncontrolled hypertension, and renal impairment. Despite its advantages, bisoprolol is not optimally utilized for managing HF in India. This consensus builds on updated evidence on the efficacy and safety of bisoprolol in HF and recommends its place in therapy with a focus on Indian patients with HF.

INTRODUCTION: There is a lack of evidence about the usefulness of exercise or rest in myasthenia gravis (MG). This study is aimed to evaluate the efficacy and safety of exercise or rest in MG. METHODS: In a single-center open-labeled randomized controlled trial, the patients with mild to moderate MG were randomized to 30-min walk or rest in addition to the standard treatment. The primary endpoint was 50% improvement in the MG Quality of Life (MG-QOL15), and secondary endpoints were change in the Myasthenic Muscle Score (MMS), MG Activities of Daily Living (MGADL), grip strength, dose of acetylcholine esterase inhibitor and prednisone, 6-min walk test (6MWT), decrement in trapezius on the low-rate repetitive nerve stimulation test, and adverse events. The outcomes were defined at 3 months, by >50% improvement in these outcome parameters. RESULTS: Forty patients with MG were randomized to the exercise or rest arm. The 2 arms were matched for demographic and clinical parameters. The patients in the exercise arm had significantly better QOL evidenced by MG-QOL15 (p = 0.02). The secondary endpoints, distance covered in 6MWT (p = 0.007), were also better in the exercise arm without any adverse event. CONCLUSION: Regular exercise for 30 min in mild and moderate MG improves quality of life and walking distance compared to rest and is safe. CLINICAL TRIAL REGISTRATION: The clinical trial registration number is CTRI/2019/11/021869.

Unique electrocardiogram (ECG) patterns can be generated by inadvertent lead misplacements. The commonest of these is left arm-right arm (LA-RA) reversal leading to inverted lead I, right axis deviation and an upright aVR. Changes in placement of the neutral (right leg: RL) electrode with one of the LA or RA cables may produce more atypical patterns, which often mimic myocardial ischemia. We describe an unusual case wherein the ECG suggested an ectopic atrial rhythm and ischemic changes in the inferior leads. Closer scrutiny revealed a bilateral LA-LL and RA-RL (left arm- left leg and right arm- right leg) reversal. Familiarity and quick recognition of such ECG patterns shall help clinicians in avoiding diagnostic and therapeutic errors.

Healthcare systems all over the world have been enormously affected by the COVID-19 pandemic. Healthcare workers (HCWs) taking care of these patients need personal protective equipments (PPEs) standardized for full protection from droplets and aerosols carrying viral load to variable distances. There has been a surge of manufacturers supplying these protective gears in India and regulatory agencies have issued technical specifications pertaining to PPEs focusing solely on synthetic blood penetration tests (SBPTs) and keeping the upper limit of non-woven fabric to 95 g/m2 (GSM). These PPE specifications are silent on air permeability (AP) and water/moisture vapor transmission rate (WVTR/MVTR) of the fabric. As a result, most of the PPE kits, despite having appropriate SBPT certifications from regulatory agencies, have extremely poor permeability and breathability. The acceptability of PPEs by HCWs can be vastly improved when the end-users are proactively invited to participate in "comfort testing" of PPEs before getting issuance of certification for marketing. "Field testing" or "end-user trials" in which HCWs don the PPE and assess it for comfort while performing different types of clinical work, e.g., in intensive care units (ICUs), operation theaters, cath labs, etc., also takes into account a hitherto often ignored "human-comfort-factor" that not only enhances the understanding of HCWs about the need for the PPEs but can also motivate them to use it without worrying about discomfort. We hereby propose that comfort fit testing (COmfort and Material Fit is an Obviously Required Test) should be a part of the mandatory testing and certification process for PPE, so that the industry invests wisely in manufacturing PPE kits that are not only certified for fabric but are also tested for comfort factors.

RESUMO
Cardiac pacing is the only effective therapy for patients with symptomatic bradyarrhythmia. Traditional right ventricular apical pacing causes electrical and mechanical dyssynchrony resulting in left ventricular dysfunction, recurrent heart failure, and atrial arrhythmias. Physiological pacing activates the normal cardiac conduction, thereby providing synchronized contraction of ventricles. Though His bundle pacing (HBP) acts as an ideal physiological pacing modality, it is technically challenging and associated with troubleshooting issues during follow-up. Left bundle branch pacing (LBBP) has been suggested as an effective alternative to overcome the limitations of HBP as it provides low and stable pacing threshold, lead stability, and correction of distal conduction system disease. This paper will focus on the implantation technique, troubleshooting, clinical implications, and a review of published literature of LBBP.

RESUMO
STUDY QUESTION: Do the siblings of Asian Indian women with polycystic ovary syndrome (PCOS) manifest increased cardiovascular disease (CVD) risk by carotid intima-media thickness (CIMT) and brachial artery flow-mediated dilatation (FMD)? SUMMARY ANSWER: Siblings had functional endothelial dysfunction (FMD was reduced) when compared to age and BMI-matched controls while sisters but not brothers had structural endothelial dysfunction (CIMT was increased). WHAT IS KNOWN ALREADY: Siblings of women with PCOS have increased metabolic risk but it varies with ethnicity. Among Asian Indians the only previous study has shown reduced FMD in brothers. STUDY DESIGN, SIZE, DURATION: This study was a tertiary care hospital-based cross-sectional case control study in the outpatient department of the endocrine clinic over 18 months. In total, 41 brothers and 35 sisters of women with PCOS (diagnosed by 2003 Rotterdam criteria) were recruited. PARTICIPANTS/MATERIALS, SETTING, METHODS: Age (±2 years), sex and BMI- (±1 kg/m2) matched controls were selected. Cases and controls underwent clinical and biochemical investigations. Cardiologists performed doppler ultrasonogram to determine CIMT and FMD in a blinded fashion. MAIN RESULTS AND THE ROLE OF CHANCE: FMD was decreased in brothers [median 12.3% interquartile range (5.1, 19) versus 18.4% (12.6, 21.5), P = 0.002] and in sisters [10.8% (5.8, 17.2) versus 14.7% (11.4, 18.2), P = 0.027] when compared to controls. CIMT was higher in sisters [median 0.4 mm (0.35, 0.5) versus 0.3 mm (0.3, 0.4), P= 0.002] when compared to controls but not in brothers. Metabolic syndrome was more common in brothers (27% versus 5% in controls, P = 0.007) even after matching for age and BMI. Insulin resistance (homeostatic model assessment for insulin resistance and acanthosis) was higher in brothers as compared to controls. Dehydroepiandrosterone sulphate was significantly elevated in brothers. LIMITATIONS, REASONS FOR CAUTION: There may have been referral bias of patients with PCOS in a tertiary care institute, and the radiological assessment was performed by two cardiologists serially on different time frames over the study duration. Power was only 50% in CIMT for brothers. WIDER IMPLICATIONS OF THE FINDINGS: Siblings of women with PCOS had higher CVD risk over and above the already pre-existing higher metabolic risk associated with Asian Indian ethnicity and therefore the siblings require vigilant management. Endothelial dysfunction and insulin resistance seems to be a heritable trait of PCOS independent of obesity, which if confirmed in other ethnicities would have important implications. STUDY FUNDING/COMPETING INTEREST(S): Funded by Intramural Research Grant (PGI/DIR/RC/943/2013) from the Sanjay Gandhi Postgraduate Institute of Medical Sciences. No competing interests.

OBJECTIVE: Prostate cancer is the most common invasive cancer in gay and bisexual men (GBM). Despite the unique sexual and urinary concerns of this group, studies of prostate cancer rehabilitation have primarily focused on heterosexual men. GBM also have high prevalence of human immunodeficiency virus (HIV), which may be associated with lower health-related quality of life (HRQOL). We examined the association between HIV status and HRQOL in a cohort of GBM with prostate cancer. METHODS: Data from the Restore study, a cross-sectional online survey of GBM treated for prostate cancer, were used to examine this association. The Expanded Prostate Cancer Index Composite (EPIC) assessed function, bother, and summary measures in four domains: urinary, sexual, bowel, and hormone. Overall physical and mental HRQOL was assessed using the Short-Form Health Survey (SF-12). Multivariate analysis of variance and linear regression were used to evaluate the association between HIV status and HRQOL scores after adjustment for demographic and sexual characteristics. RESULTS: Of 192 participants, 24 (12.4%) reported an HIV diagnosis. After adjustment for covariates, HIV-positive status was associated with lower scores on the EPIC urinary (mean difference [MD]: -13.0, 95% CI, -21.4 to -4.6), sexual (MD: -12.5, 95% CI, -21.9 to -3.2), and bowel (MD: -5.9, 95% CI, -11.7 to -0.2) domains. No significant associations were observed between HIV status and other outcomes. CONCLUSIONS: HIV status may be associated with poorer urinary, sexual, and bowel HRQOL in GBM prostate cancer survivors.

INTRODUCTION: We assessed cardiac function (CF) in celiac disease (CD) patients and the effect of gluten-free diet (GFD) on CF. METHODS: Prospective evaluation of CF using conventional and tissue doppler echocardiography in 50 CD patients (age 4.2 ± 1.1 years) at diagnosis and after a year of GFD (group 1), 100 CD children (group 2; 47 compliant and 53 non-compliant) in follow-up and 25 healthy controls. RESULTS: Untreated CD (n = 50) children had larger left ventricle end diastolic dimension (35.33 ± 0.87 vs. 32.90 ± 0.91 mm; p = .04), reduced (<55%) left ventricular ejection fraction (20% vs. 0%; p = .01) and a higher (>0.6) myocardial performance index (MPI, 66% vs. 0%; p ≤ .01) as compared to controls. Re-evaluation after one year with good dietary compliance showed changes in isovolumic relaxation time (72.5 ± 4.2 vs. 50.62 ± 2.69; p = .0001) and deceleration time (121.05 ± 10.1 vs. 99.87 ± 8.5; p = .02), reflecting improved cardiac diastolic function. GFD compliant patients had lower MPI than non-compliant (0.60 ± .03 vs. 0.66 ± .08; p = .04), reflecting improvement in load-independent echocardiographic parameters. CONCLUSIONS: Subclinical cardiac dysfunction is common in CD children at diagnosis. Improvement in echocardiographic parameters occurs with GFD and non-compliant children continue to have persistent cardiac dysfunction.

BACKGROUND: Right ventricular (RV) function has prognostic value in terms of survival and symptoms in patients with mitral stenosis (MS). The aim of the study was to assess RV function by strain analysis in the patients of mitral stenosis and the effect of percutaneous transvenous mitral commisurotomy (PTMC) on it. METHODS: Eighty patients of severe mitral stenosis without overt right heart failure and normal sinus rhythm undergoing PTMC were included. Conventional echocardiography and RV function by TDI-derived longitudinal strain and strain rate were assessed prior and 24 hours post PTMC and compared with 40 healthy age-matched controls. RESULTS: Eighty subjects (mean age 31 + 10 years, 70% females) were included. Patients with MS had significantly lower RV strain of basal and mid-free wall, tricuspid annular plane systolic excursion (TAPSE), and RV fractional area change (FAC) as compared to controls. There was a significant increase in pre- and post-PTMC in TAPSE (19.5 ± 2.7 mm vs 21.4 ± 3.3 mm; P < 0.001), RV basal free wall longitudinal strain (-24.4 + 6.1% vs -27.7 + 5.8%; P < 0.001), and right ventricle mid-free wall longitudinal strain (-25.6 + 5.5% vs -28.6 + 5.1%; P < 0.001), respectively. There was no significant change in RV Tei index (0.43 + 0.06 vs 0.41 + 0.03; P = 0.06). There was a significant negative correlation between RV longitudinal strain and right ventricle systolic pressure, left atrium diameter, RV Tei index, and pulmonary capillary wedge pressure, and positive correlation between RV FAC and RV TAPSE. CONCLUSION: Patients with severe MS with normal RV systolic function had decreased RV strain, which was significantly increased after a successful PTMC with reduction in afterload.
