Background Tetralogy of Fallot is a severe type of congenital heart disease (CHD) and one of the leading indirect causes of mortality & morbidity among women with CHD. We came across a rare case of an uncorrected Tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries in pregnancy. Case presentation We are reporting the challenges in managing a pregnancy of 25-years-old G3 P0110, previous one stillbirth and who was diagnosed to have congenital heart disease during pregnancy following spontaneous abortion. Conclusions This case report highlights the role of multidisciplinary care in managing such a high risk case. It also emphasizes the role of cardiac examination of every woman before pregnancy so that definitive treatment or optimization can be done in time for a better outcome.

Branchial arches represent embryological precursors of the face, neck, and pharynx, and developmental abnormalities of these branchial arch derivatives can lead to airway anomalies. We report definitive repair of the fistula in an infant with a rare congenital laryngopharyngo-cutaneous fistula. This is the first report that describes a 2-stage fiberoptic intubation, a challenging technique performed for airway management of the aforementioned fistula in a patient with a difficult airway.

Background Post myocardial infarction ventricular septal rupture (PMI-VSR) is a dreaded mechanical complication of acute coronary syndromes. Given that surgical mortality approaches 50%, it is pragmatic that the risk factors for mortality and outcomes after surgical correction of PMI- VSR are carefully scrutinized. Methods We performed a single-center, retrospective cohort study of 35 patients presenting for surgical closure of post myocardial infarction ventricular septal rupture over six years. We reviewed patient characteristics, clinical, echocardiographic, angiographic and perioperative risk factors which may affect mortality after surgical repair of PMIVSR and 30 day and one year mortality rates of these patients. Univariate and multivariate logistic and cox proportional hazard regression analysis was used to identify predictors of operative and overall mortality. Long term survival was presented with Kaplan-Meier Survival Curve. Results Sixteen patients (46%) were in cardiogenic shock. Concomitant coronary artery bypass grafting (CABG) was done in 22 patients (63%) but did not influence survival. Preoperative thrombolysis was done in 12 patients (34%) out of which 10 (53%) survived Operative mortality was 46% and one-year mortality was 49%. Multivariate analysis identified preoperative thrombolysis: Hazards ratio, 0.12; 95% CI, 0.02-0.61; p value of 0.01, as significant independent predictor of survival in PMIVSR cohort. Conclusions Preoperative thrombolysis is associated with decreased odds of operative and overall mortality after surgical repair in PMIVSR patients.

Background: Nitrous oxide has been used during surgical anesthesia for many years. However, information about occupational exposure and related risks due to N2O exposure to the health care personnel in India are still poorly understood. Here, we measured the residual N2O levels during the working time of operation theatre room air in our tertiary care hospital. Material and Methods: The air samples were collected from different anesthesia exposure zones on different days for quantitative analysis of available N2O in the room air in respective areas. Nitrous oxide concentrations in the ambient air were also measured to compare outdoor and indoor levels. Observations and Results: Nitrous oxide mixing ratios were found to be 65.61 ± 0.05 ppm, 281.63 ± 0.43 ppm, and 165.42 ± 0.42 ppm in elective surgical theatres of the hospital on three different days whereas in emergency operation theatres of the same hospital levels of N2O were 166.75 ± 0.07 ppm, 510.19 ± 0.30 ppm and 2443.92 ± 0.64 ppm during same period. In elective pediatric surgical theatres levels of N2O were found to be 1132.55 ± 0.70 ppm and 362.21 ± 0.13 ppm on two days of reading respectively. Outdoor levels of N2O in contrast found 0.32 ± 0.01 ppm and was lower by a factor of 1000. Conclusion: We observed the very high ambient concentration of N2O in the surgical theatre's environment (up to 2443 ppm) and recovery areas (up to 50 ppm). It was 5 to 50 times higher ambient concentration of N2O than REL in OT area and 200-7000 times higher ambient concentration of N2O than outdoor ambient air in all surgical theaters other than CTVS OTs.

Hydatid cyst (HC) is a human parasitic disease caused by the larval stage of Echinococcus granulosus. Cardiac involvement is rare and occurs in 0.5%e2% of patients with hydatid cyst, but isolated pericardial hydatid cyst is rarer still. We present two cases of isolated pericardial hydatid cyst who presented with precordial chest pain and dyspnea. In both the cases, HC were diagnosed by transthoracic echo (TTE), Computed Tomography/Magnetic Resonance and positive hydatid serology. Intraoperatively transesophageal echo (TEE) revealed unilocular transitional cystic lesion the transverse pericardial sinus in one case and multilobulated active cystic lesion in another. The report highlights the role of TEE in diagnosis and evaluation of cardiac HC. Both the cases underwent surgical resection followed by albendazole therapy to prevent recurrence. Key words: Cardiac echinococcosis, Echinococcus pericardial effusion, Isolated pericardial hydatid cyst, Pericardial location, Transesophageal echocardiography.

Pericardial effusion (PE) remains an important cause of morbidity after cardiac surgery, and it can be life threatening when tamponade leads to hemodynamic compromise. Transthoracic echocardiography is the most important tool for diagnosis, grading, performing the pericardiocentesis procedure and follow up of post surgical pericardial effusions. The present case highlights the unique technique of posterior approach for pericardiocentesis for a post surgical effusion in the presence of a large left pleural effusion which otherwise would have required surgical drainage. Key words: Pericardial effusion, Pericardiocentesis, Posterior approach, Echocardiography.
