RESUMO
BACKGROUND/AIM: Double-chambered right ventricle is a rare and progressive condition that is characterised by obstruction of the right ventricular tract. Double-chambered right ventricle is usually associated with ventricular septal defect. Early surgical intervention is recommended in patients with these defects. Based on this background, the present study aimed to review early and midterm outcomes of primary repair after double-chambered right ventricle. METHODS: Between January 2014 and June 2021, 64 patients with a mean age of 13.42 ± 12.31 years underwent surgical repair for double-chambered right ventricle. The clinical outcomes of these patients were reviewed and assessed retrospectively. RESULTS: An associated ventricular septal defect was present in all the recruited patients; 48 (75%) patients of sub-arterial type, 15 (23.4%) of perimembranous, and 1 (1.6%) patient of muscular type. The patients were followed up for a mean period of 46.73 ± 27.37 months. During their follow-up, a significant decrease in the mean pressure gradient from 62.33 ± 5.52 mmHg preoperatively to 15.73 ± 2.94 mmHg postoperatively was observed (p < 0.001). Notably, there were no hospital deaths. CONCLUSIONS: The development of double-chambered right ventricle in association with ventricular septal defect results in an increased pressure gradient within the right ventricle. The defect needs correction in a timely manner. In our experience, the surgical correction of double-chambered right ventricle is safe and shows excellent early and mid-term results.

Rheumatic heart disease (RHD) is an autoimmune sequel of pharyngitis and rheumatic fever that leads to permanent heart valve damage, especially the mitral valves. The mitral valves, which are responsible for the binding of auto-antibodies during immune response generation, lead to valve scarring and eventually valves dysfunction. Recently, exosomes (EXOs), the nano-sized vesicles, which range in size from 30 to 150 nm, are reported in various cardiovascular physiological and pathological processes. These vesicles are found in several body fluids such as plasma, serum, and also in cell culture media. Exosomal cargo contains proteins, which are taken up by the recipient cells and modulate the cellular characteristics. The role of exosomal proteins in RHD is still obscure. Hence, the present study has been designed to unveil the exosomal proteins in disease severity during RHD. In this study, the exosomes were isolated from biological fluids (serum and pericardial fluid) of RHD patients as well as from their respective controls. Protein profiling of these isolated exosomes revealed that alpha-1 antitrypsin is up-regulated in the biological fluids of RHD patients. The enhanced levels of exosomal alpha-1 antitrypsin, were further, validated in biological samples and mitral valve tissues of RHD patients, to correlate with the disease severity. These findings suggest an association of increased levels of exosomal alpha-1 antitrypsin with the RHD pathogenesis.

BACKGROUND: The role of nebulized amphotericin B (NAB) in managing pulmonary mucormycosis (PM) is unknown. METHODS: In this open-label trial, we randomized PM subjects to receive either intravenous liposomal amphotericin B (control arm, 3-5 mg/kg/day) alone or along with nebulized amphotericin B deoxycholate (NAB, 10 mg twice a day, every alternate day). The primary outcomes were: (1) overall response ('success' [complete or partial response] or 'failure' [stable disease, progressive disease, or death]) at 6 weeks; and (2) the proportion of subjects with adverse events (AE). The key secondary outcome was 90-day mortality. We performed a modified intention-to-treat (mITT) analysis where we included only subjects receiving at least a single dose of NAB. RESULTS: Fifteen and 17 subjects were randomized to the control and NAB arms; two died before the first dose of NAB. Finally, we included 30 subjects (15 in each arm; mean age 49.8 years; 80% men) for the mITT analysis. Diabetes mellitus (n = 27; 16/27 were COVID-19-associated PM) was the most common predisposing factor. The overall treatment success was not significantly different between the control and the NAB arms (71.4% vs. 53.3%; p = .45). Twenty-nine subjects experienced any AE, but none discontinued treatment. The 90-day mortality was not significantly different between the control (28.6%) and NAB arm (53.3%; p = .26). CONCLUSION: Adjunctive NAB was safe but did not improve overall response at 6 weeks. A different dosing schedule or nebulized liposomal amphotericin B may still need evaluation. More research is needed to explore other treatment options for PM.

INTRODUCTION: Double-orifice mitral valve or left atrioventricular valve is a rare congenital cardiac anomaly that may be associated with an atrioventricular septal defect. The surgical management of double-orifice mitral valve/double-orifice left atrioventricular valve with atrioventricular septal defect is highly challenging with acceptable clinical outcomes. This meta-analysis is aimed to evaluate the surgical outcomes of double-orifice mitral valve/double-orifice left atrioventricular valve repair in patients with atrioventricular septal defect. METHODS AND RESULTS: A total of eight studies were retrieved from the literature by searching through PubMed, Google Scholar, Embase, and Cochrane databases. Using Bayesian hierarchical models, we estimated the pooled proportion of incidence of double-orifice mitral valve/double-orifice left atrioventricular valve with atrioventricular septal defect as 4.88% in patients who underwent surgical repair (7 studies; 3295 patients; 95% credible interval [CI] 4.2-5.7%). As compared to pre-operative regurgitation, the pooled proportions of post-operative regurgitation were significantly low in patients with moderate status: 5.1 versus 26.39% and severe status: 5.7 versus 29.38% [8 studies; 171 patients]. Moreover, the heterogeneity test revealed consistency in the data (p < 0.05). Lastly, the pooled estimated proportions of early and late mortality following surgical interventions were low, that is, 5 and 7.4%, respectively. CONCLUSION: The surgical management of moderate to severe regurgitation showed corrective benefits post-operatively and was associated with low incidence of early mortality and re-operation.

BACKGROUND: Pulmonary mucormycosis has been associated with high mortality (reported up to 100%) in renal transplant recipients. METHODS: This was a retrospective analysis of renal transplant patients with pulmonary mucormycosis between April 2014 and March 2020, who underwent surgical resection of the affected lung along with liposomal amphotericin therapy. Patients with lower respiratory illness features underwent chest X-ray, high-resolution computed tomography of the chest, and those with suspicious findings underwent analysis of bronchioloalveolar fluid and transbronchial lung biopsy. Patients with histological or microbiological evidence of mucormycosis were started on liposomal Amphotericin B. Tacrolimus and mycophenolate mofetil were stopped at the time of diagnosis. RESULT: Ten patients underwent combined management, while five patients were managed medically. At last follow up, seven out of ten patients (70%) who underwent combined management and two of the five patients (40%) who were managed medically, had a mean survival of 28.86 months (sd = 15.71, median = 25) and 14.17 months (sd = 12.21, median = 18), respectively, post-diagnosis of pulmonary mucormycosis. CONCLUSION: Surgical resection combined with antifungals in the perioperative period and decreased immunosuppression may improve the outcomes in renal transplant patients with pulmonary mucormycosis.

Background & objectives: Standard donor lung preservation with cold flush and storage allows up to six hours between retrieval of lungs from the donor and transplantation in the recipient. Ex vivo lung perfusion (EVLP) systems mimic physiological ventilation and perfusion in the donor lungs with potential for prolonged lung preservation and donor lung reconditioning. In this study, it was aimed to perform EVLP on discarded donor lungs using a locally developed EVLP system. Methods: Equipment that are routinely used for cardiac surgeries were collected and a functional EVLP system was assembled. This system was used on five pairs of lungs retrieved from brain-dead organ donors. The lungs were ventilated and pulmonary circulation was continuously perfused with a solution containing oxygen and nutrients for four hours. The system was tested without red blood cells (RBCs) added to the solution (acellular group; n=3; A1, A2 and A3) and also with RBCs added to the solution (cellular group; n=2; C1 and C2). Results: The EVLP system was successfully used in four (A1, A2, A3 and C2) of the five lung pairs. Mechanical and gas exchange functions of the lungs were preserved in these lung pairs. One lung pair (C1) worsened and developed pulmonary oedema. Histopathological examination of all five lung pairs was satisfactory at the end of the procedure. Major challenges faced were leakage of solution from the system and obstruction to drainage of RBCs containing solution from the lungs. Interpretation & conclusions: The results of the present study suggest that, it is possible to maintain the lungs retrieved for transplantation in a physiological condition using a locally prepared EVLP system and a solution without RBCs.

Literature on COVID-19-associated pulmonary mucormycosis (CAPM) is sparse. Pulmonary artery pseudoaneurysm (PAP) is an uncommon complication of pulmonary mucormycosis (PM), and rarely reported in CAPM. Herein, we report five cases of CAPM with PAP managed at our center and perform a systematic review of the literature. We diagnosed PM in those with clinico-radiological suspicion and confirmed it by microbiology or histopathology. We encountered five cases of CAPM with PAP (size ranged from 1 × 0.8 cm to ~ 4.9 × 4.8 cm). All subjects had diabetes and were aged 55-62 years (75% men). In two cases, COVID-19 and mucormycosis were diagnosed simultaneously, while in three others, COVID-19 preceded PM. One subject who underwent surgery survived, while all others died (80% mortality). From our systematic review, we identified one additional case of CAPM with PAP in a transplant recipient. CAPM with PAP is rare with high mortality. Early diagnosis and multimodality management are imperative to improve outcomes.

INTRODUCTION: In patients with total anomalous pulmonary venous connection (TAPVC), left atrium (LA) is small and suprasystemic pulmonary artery (PA) pressures may be present in some patients. In our study, we studied the relationship between surgical LA enlargement and patent foramen ovale (PFO) creation separately on the outcomes of patients with TAPVC. MATERIALS AND METHODS: Out of the 130 patients operated in our institute between January 2014 and December 2020, LA was enlarged in 60 patients. LA enlargement was done using a larger patch for atrial septal defect (ASD) closure. Thus, the LA volume was increased by shifting the patch towards the right atrium (RA). Suprasystemic or high PA pressures were present in 60 patients. In 33 patients, PFO was created. Early surgical outcomes were determined on the basis of vasoactive inotropic score (VIS), hours of ventilation, hours of inotropic support, intensive care unit (ICU) stay, and hospital stay. RESULT: Between the LA enlarged and nonenlarged group there was statistically significant less VIS score (18 [13-27.5] vs. 24 [18-30], p value .019), hours of ventilation (23 [16-46.5] vs. 26 [18-60], p value .039), hours of inotropic support (45.5 [30-72] vs. 55 [38-84], p value .038), and ICU stay (7 [5-9] vs. 8 [7-10] p value .0352) and statistically nonsignificant less hospital stay (11.5 [9-13] vs. 12 [9-14], p value .424). In patients with preoperative suprasystemic or high PA pressures, there was a statistically significant less VIS score (16 [11-23.5] vs. 18 [13-25], p value .044), hours of ventilation (20 [14-37] vs. 22 [18-39], p value .038), hours of inotropic support (34 [29.5-71] vs. 38 [30-78], p value .042), and hospital stay (9 [5-12] vs. 11 [9-14], p value .038) and statistically nonsignificant less ICU stay (7 [5.5-9] vs. 7 [6-9], p value .886) in the group with a PFO with respect to the other group in which no PFO was created. CONCLUSION: In patients with TAPVC, LA can be enlarged by using a large ASD patch and thus shifting the septum towards RA. Early surgical outcomes were improved with LA enlargement. In patients with suprasystemic or high PA pressures, leaving a PFO improved the postoperative outcomes.

Left atrial mass after excision of a left atrial myxoma may occur due to residual or additional masses, such as biatrial or multicentric myxomas and inverted left atrial appendage. In this E-challenge, the authors present a case where intraoperative transesophageal echocardiography allowed visualization of a left atrial mass after excision of a left atrial myxoma. Detailed examination demonstrated that the mass was due to left atrial dissection that progressed to rupture, allowing its early detection and repair. A high index of suspicion, as well as coordination between the surgeon and the perioperative echocardiographer, played a crucial role in the detection and management of this complication.

PURPOSE: The aims of this study were to determine the utility of transesophageal echocardiography (TEE) for identifying spinal canal structures and epidural catheter position and to assess the effect of catheter position on intraoperative hemodynamics and quality of postoperative analgesia. METHODS: Twenty-six adult patients undergoing thoracic surgery were included in this prospective, observational study. An epidural catheter was inserted 7.5 cm or more into the thoracic epidural space using a midline approach and a loss-of-resistance technique. A pediatric TEE probe was inserted after induction of general anesthesia. It was used to identify the spinal canal structures, the catheter tip position in the epidural space, and the spread of injected local anesthetic. Intraoperative hemodynamics, postoperative visual analogue scale (VAS) pain scores, and the need for rescue epidural doses were recorded and compared between groups determined by their catheter position. RESULTS: Two subjects were excluded from the study because of an intrathecally positioned epidural catheter. The remaining 24 subjects were divided into two groups based on TEE-determined epidural catheter position: posterior (Gr-P) or lateral (Gr-L). Spinal canal structures and the epidural catheter was successfully identified in all patients. The epidural catheter was located posteriorly in 20 (83%) patients and laterally in four (17%) patients. The spread of the local anesthetic was bilateral in all Gr-P patients, whereas it was unilateral in all but one of the Gr-L patients. Compared to Gr-P patients, Gr-L patients had higher heart rates and blood pressures at various time points after local anesthetic administration until the end of surgery (P = 0.02 to < 0.001). Postoperative VAS scores (P = 0.02) and the median number of rescue analgesic doses required during the intraoperative and postoperative periods were also higher in Gr-L patients (P < 0.001). CONCLUSION: Transesophageal echocardiography reliably identified spinal canal structures and the position of epidural catheters in the epidural space in adult patients. Posteriorly located epidural catheters appear to provide better epidural analgesia than laterally situated catheters.

Pulmonary gangrene is a life-threatening condition, which represents the fulminant end of the infectious lung diseases usually caused by polymicrobial infection. Aerobic and anaerobic bacteria act synergistically to produce massive tissue necrosis which might be augmented by the angioinvasive nature of fungi like Mucor. We report a successfully treated case of pulmonary gangrene in a poorly controlled diabetic patient, which was associated with polymicrobial infection. It was caused by Rhizopus spp., Staphylococcus aureus, Klebsiella pneumoniae and unusual anaerobic organism Sarcina. This is the first report describing the presence of Sarcina organisms in a case of pulmonary gangrene. Adequate glycemic control, treatment of coexisting polymicrobial infection and prompt antifungal therapy along with surgical intervention were useful in the index patient. This case also highlights the effectiveness of combined medical and surgical intervention in a case of pulmonary gangrene.

ABSTRACT: Cardiac metastases of lung cancers are common and are associated with serious complications. Locally aggressive lung tumors have the potential to extend into the left atrium via pulmonary veins, which can further complicate by embolizing into the systemic circulation. Pulmonary blastoma (PB) is one of the rare forms of primary lung malignancy and is locally aggressive. We report a rare case of 30 years old male patient who underwent left pneumonectomy for PB. During resection, the tumor was embolized into the descending thoracic aorta, leading to an acute circulatory compromise of both the lower limbs.

Pulmonary blastoma (PB) is an exceedingly rare and aggressive malignant lung neoplasm that has distinct biphasic morphology. In this report, we document rare manifestations and molecular alterations in PB. A 59-year-old non-smoker female, presented with cough and hemoptysis for 4 months. The high-resolution computed tomography chest scan showed a 3.5x2.7 cm mass in the basal segment of the left lung. Positron emission tomography and computed tomography revealed a fluorodeoxyglucose avid lobulated mass in the superior segment of the lower lobe of the left lung. On core biopsy, the diagnosis of pleomorphic carcinoma in a background of adenocarcinoma was made. A definite diagnosis of pulmonary blastoma was established on the left lung lobectomy specimen based on morphological and immunohistochemical findings. Post-surgical biopsy from the scalp swelling showed metastatic deposits. On Next Generation Sequencing (NGS), in addition to conventional CTNNB1 gene mutation, new pathogenic MYCN and ATM gene mutations were detected. Post-chemotherapy, the patient was doing well after 10 months of close follow-up. PB exhibited rare associations in the form of non-smoker status, scalp metastasis, and MYCN and ATM gene mutations on NGS in addition to conventional CTNNB1 gene mutation. Large cohort studies are required to discover the incidence, significance and therapeutic implications of these co-existing pathogenic molecular alterations in PB.

Pulmonary valve interventions are one of the most common cardiac interventions that are being performed in patients with a wide variety of congenital heart diseases, more so in adults with congenital heart disease. Despite the introduction of various different reconstructive techniques and conduits, the ideal option still remains elusive. Lack of growth and re-operation for conduit replacement remains an Achilles heel in such conduits. So, surgeons have constantly tried to evolve surgical techniques that would obviate their use and allow age-related growth. The Ozaki procedure has proven to be technically reproducible and have excellent mid-term results in the aortic position in adults. Extending the same principle for reconstruction of the pulmonary valve can prove to be a reasonable alternative.

RESUMO
Ventricular septal defect (VSD) is a catastrophic acute myocardial infarction (MI) complication. Despite a significant reduction in the prevalence of post-MI VSD with the advancement of surgical techniques, it is still considered fatal with a high mortality rate. The trends in the clinical outcomes of patients with post-MI VSD show discretion due to the complexity of the disease. Therefore, the present analysis aimed to evaluate the surgical outcomes and associated risks in the patients of post-MI VSD. A thorough literature survey resulted in 40 studies of our interest. The pooled proportion of differential variables, including the incidence of cardiogenic shock, 30-day survival, and overall mortality, were estimated using Bayesian hierarchical models. The risk difference was estimated for the location of MI and VSD and mortality in patients with coronary artery bypass graft (CABG). In addition, the heterogeneity tests for inconsistency and publication biases using Egger's and Begg's tests were also estimated. The analysis revealed a significant risk difference of 0.23 and 0.27 for the anterior vs. posterior location of MI and VSD, respectively. Further, the pooled proportion of 30-day survival and mortality was found to be 54.43% (95% credible interval (CI): 52.88-55.98%) and 48.22% (95% CI: 4-12.3%), respectively. Moreover, the heterogeneity test revealed significant inconsistencies in all the datasets with an I2 index of >90% (p<0.0001). Lastly, the publication bias results suggested no evidence of asymmetry and small-study effects. Conclusively, the surgical management of post-MI VSD patients is considered beneficial; however, the outcomes signify its fatal behavior.
RESUMO
BACKGROUND/AIM: Surgical repair techniques and management of patients with atrioventricular septal defect (AVSD) have progressed over the last few decades. Early and definitive interventions have become the choice of treatment for these patients. Based on this background, we aimed to review the early and mid-term outcomes of primary AVSD repair. METHODS: A total of 53 patients with a mean age of 3.45 ± 5.67 years underwent definitive repair for AVSD between January 2014 and June 2021. The clinical data including age, type of defect, associated co-anomalies, symptoms, pulmonary hypertension, etc. were collected and assessed retrospectively. Mitral regurgitation (MR) as a clinical outcome was assessed at 0, 1, 2, and 5 years. RESULTS: Among the recruited patients, 35 (66.1%) were male and 18 (33.9%) were female. Of 53 patients, repair for the complete defect was done in 38 (71.69%) patients, repair for intermediate/partial defect was done in 15 (23.1%) patients, and one patient underwent repair for incomplete type. Other associated co-anomalies were anterior mitral leaflet (12 (22.6%)), atrial and ventricular septal defect (VSD) (30 (56.6%)), and patent ductus arteriosus (PDA) (11 (20.8%)). Different procedures for surgical repair included patch closure, cleft repair, and polytetrafluoroethylene (PTFE) VSD closure. After repair, the mean follow-up period was 46.73 ± 27.37 months. Overall mortality was 3.78% (2/53), and two patients underwent reintervention due to symptomatic severe MR. CONCLUSIONS: A definitive and timely correction of AVSD shows satisfactory early and mid-term results.
RESUMO
The surgical treatment options for pediatric aortic valve disease are limited and have debatable long-term durability. In the current situation, the Ross procedure is considered in children for aortic valve disease(s). It is a complex surgical procedure with the risk of neo-aortic dilatation, converting a single valve disease into double valve disease, and associated with future re-interventions. Conversely, the Ozaki procedure has shown promising results in adults. Thus, the present study aimed to provide comparative evidence on the effectiveness and safety of the Ozaki versus Ross procedure for pediatric patients by performing a meta-analytic comparison of reporting outcomes. A total of 15 relevant articles were downloaded and among them, seven articles (one prospective study, five retrospective studies, and one case series) were used in the analysis. Primary outcomes such as physiological laminar flow pattern and hemodynamic parameters, and secondary outcomes such as hospital stays, adverse effects, mortality, and numbers of re-intervention(s) were measured in the meta-analysis. There were no significant differences in the age of patients between children who underwent the Ozaki procedure and those who underwent the Ross procedure at the time of surgeries. The Ozaki procedure is a good solution to an aortic problem(s) similar to the Ross procedure. Unlike the Ross procedure, the Ozaki procedure has restored a physiological laminar flow pattern in the short-term follow-up without the bi-valvular disease. Mean hospital stays (p = 0.048), mean follow-up (p = 0.02), adverse effects (p = 0.02), death, and numbers of re-intervention(s) of children who underwent the Ozaki procedure were fewer than those who underwent the Ross procedure. The time required for re-intervention(s) is higher for children who underwent the Ozaki procedure than those who underwent the Ross procedure. None of the procedures, including the Ozaki procedure for aortic valve disease(s), has significant effects on hemodynamic parameters and the frequent death rate of children after surgeries. Based on our analysis, we may suggest the Ozaki procedure for aortic valve disease surgery in children.
