Percutaneous coronary intervention (PCI) is an universally accepted and standardized procedure for obstructive coronary artery diseases with minimal complication rates, including iatrogenic coronary artery perforation (CAP). Most of the coronary perforations present earlier during the time of procedure or immediately after the procedure. Delayed presentation is very rare and presents within days or weeks. The present case showed the delayed atypical presentation of stent extrusion as a swelling in the right hypochondrium three years after the procedure. This is a rare case of long standing right coronary artery stent extrusion presented atypically as a right hypochondrial swelling.Severe symptomatic tricuspid regurgitation (TR) with right heart failure is associated with significant morbidity and mortality. Medical therapy is often ineffective and surgical correction is not feasible due to prohibitive perioperative risk. Transcatheter caval valve implantation (CAVI) is an evolving therapeutic option for this condition. It refers to the heterotopic placement of a valve into the inferior vena cava alone or with a second valve in the superior vena cava to restrict the backflow from the failing tricuspid valve. We hereby describe a patient with previous mitral valve surgery with chronic severe TR who underwent successful CAVI at our institute.The diagnosis of paradoxical emboli remains elusive in many cases. The causal association between the thrombotic source, the intracardiac shunt, and the final emboli location is seldom demonstrated. We present the case of a 42-year-old woman admitted to the hospital with a third stroke. The presence of a thrombus in transit through a patent foramen ovale (PFO), a deep vein thrombosis (DVT), bilateral pulmonary emboli, and an acute cerebral infarct were concurrently documented.Holt-Oram syndrome is a rare autosomal disorder with cardiac, vascular, and upper limb anomalies. Previous reports have described anesthetic and perioperative challenges including difficulty in arterial and venous cannulations, airway management and rhythm, and temperature abnormalities. There are no previous reports of absent right superior vena cava (SVC) in children with Holt-Oram syndrome. We present images of a case where the diagnosis of absent right SVC with persistent left SVC was made with intraoperative transesophageal echocardiography and discuss the anesthetic and perfusion implications of such findings.

Postoperative pulmonary complications in cardiac surgery increase mortality and morbidity. High flow nasal cannula oxygen therapy (HFNC) is one of the preventive measures to reduce the incidence of lung complications. HFNC can decrease dyspnea and improve physiologic parameters after extubation, including respiratory rate and heart rate, compared with conventional oxygen therapy. In this study, we evaluated the role of THRIVE (Transnasal Humidified Rapid Insufflation Ventilatory Exchange) after extubation.

We prospectively randomized 60 adults aged between 18 and 65 years undergoing elective cardiac surgery to either High flow oxygen therapy using THRIVE (Group A) or conventional nasal cannula (group B). Arterial paO2, paCO2, pH at three points of time i.e., 1, 2, 4 hrs after extubation were evaluated using arterial blood gas analysis. Ventilation duration, the incidence of reintubation, sedation score, mortality, and other complications were also assessed.

Thirty adults in each group had comparable patient characteristics. There was a statistically significant decline in paCO

in group A at 1, 2, 4 hrs post extubation (P = 0.022, 0.02, <0.001) with a significant increase in oxygenation (P < 0.001) when compared to group B.ICU stay duration was similar between two groups. No complications were noted in both groups.

THRIVE is safe to use following extubation in adult cardiac surgical patients.

Atrial fibrillation (AF) is the most common arrhythmia in adults. For over 90% of non-valvular AF patients, the left atrial appendage is the primary site of thrombus formation. Left atrial appendage occlusion using the FDA-approved Watchman™ device has been shown to have better clinical outcomes with minimal post-procedural complications when compared to warfarin therapy for patients with contraindications to anticoagulation. Traditionally, this procedure requires an endotracheal tube (ETT) to facilitate transesophageal echocardiography (TEE) guidance. However, recently supraglottic airway (SGA) has emerged as a feasible, non-inferior alternative to ETT for procedures requiring TEE.

Compare outcomes between TEE guided Watchman™ procedures performed with a SGA versus ETT.

The optimal dose of tranexamic acid in minimizing perioperative bleeding is uncertain. We compared efficacy of two different doses of tranexamic acid in reducing post-operative blood loss and its side effects in patients with congenital cyanotic heart disease undergoing cardiac surgery.

Prospective observational study at a pediatric cardiac center in South India.

Consecutive cyanotic patients undergoing cardiac surgery were divided into groups I and II to receive either 10 mg/kg or 25 mg/kg of tranexamic acid administered as triple dose regime after induction, during cardiopulmonary bypass, and after protamine. Post-operative blood loss at 24 hours, blood component utilization, incidence of renal dysfunction and seizures were compared.

Totally, 124 patients were recruited, 62 in each group. The pre-operative variables and cardiopulmonary bypass time were comparable. Patients receiving 25 mg/kg had lower post-operative blood loss compared to patients in lower dose group (8.04 ± 8.89 vs 12.41 ± 19.23 ml/kg/24 hours, P = 0.03). There was no difference in the transfused volume of packed red cells (9.21 ± 7.13 ml/kg vs 12.41 ± 9.23 ml/kg, P = 0.712), fresh frozen plasma (13.91 ± 13.38 ml/kg vs 11.02 ± 8.04 ml/kg, P = 0.19), platelets (9.03 ± 6.76 ml/kg vs 10.90 ± 6.9 ml/kg, P = 0.14) or cryoprecipitate (0.66 ± 0.59 ml/kg vs 0.53 ± 0.54 ml/kg, P = 0.5) in group II and I, respectively. Two patients developed renal dysfunction secondary to low cardiac output in lower dose group. There were no seizures.

Tranexamic acid administered at a dose of 25 mg/kg as triple dose regime is associated with lower post-operative blood loss compared to a lower dose of 10 mg/kg in cyanotic patients undergoing cardiac surgery without causing major adverse effects.

In recent years, increasing awareness and early detection has made total anomalous pulmonary venous connection (TAPVC) a relatively common congenital heart condition presenting to children's heart centers in India. The condition was associated with significant morbidity and mortality in the past due to various reasons. Improvement in perioperative management has markedly changed the outcomes of TAPVC even in a developing country.

All patients with TAPVC operated between June 2013 and February 2018 at our center were included in the study. Post repair 30-days mortality and morbidity were analyzed.

A total of 166 patients were divided into supracardiac (91), infracardiac (45), cardiac (18), and mixed type (12). It also divided our cohort into obstructed and unobstructed types. The duration of inotrope usage in the obstructed group was significantly higher compared to the unobstructed group. Statistically, significant difference was noticed for the duration of ventilation 85.17 ± 80.94 h in obstructed typetilation, and ICU stay were seen in obstructed TAPVC in comparison to unobstructed TAPVC patients. Duration of CPB or aortic cross-clamp had no effects on morbidity parameters. find more In our cohort of TAPVC patients, lower BSA was strongly associated with the longer requirement of inotropes, prolong ventilation time, and ICU stay. The risk factors for mortality in our study include lower BSA, infracardiac, and obstructed type of TAPVC.

To evaluate the correlation between stroke volume variation (SVV) and inferior vena cava distensibility index (dIVC) as a marker for fluid responsiveness in mechanically ventilated hypotensive intensive care unit (ICU) patients.

This study is designed as prospective observational study conducted in patients admitted to an ICU who were mechanically ventilated and experienced a hypotensive episode.

A fluid challenge of 10 mL/kg ringer's lactate was given over 20 min.

Hemodynamic parameters as well as SVV, IVCmax, IVCmin, dIVC, and cardiac output (CO), were recorded at a different time interval. An increase in ≥15% of CO was taken as fluid responsiveness.

Out of 67 patients, 67.2% responded to fluid challenge. Pearson's correlation graph at baseline showed a strong positive correlation between dIVC and SVV with r = 0.453, (P < 0.002). Non-responders also had a strong positive correlation (r = 0.474) at the baseline. Bland Altman's analysis of the correlation between dIVC and SVV post-fluid challenge showed a mean difference of - 4.444, with 1.49% of the values falling outside the limits of agreement (18.418 and -27.306). This difference was clinically significant. Pearson's correlation graph post-fluid challenge showed a moderately strong positive correlation between dIVC and SVV with r = 0.298 and P value = 0.047, which was statistically significant. Also, non-responders had a weak correlation as compared to the responder's group, r = 0.364 and P value = 0.095, which was not clinically significant. There was no significant difference in the trend of dIVC and SVV values between the non-surgical and surgical groups, nor was there any gender difference analyzed in the study.

This study ascertains the positive correlation between dIVC and SVV and justifies its use in a clinical setting of hypotension suspected to be due to hypovolemia.

Myocardial preconditioning using volatile anesthetics such as isoflurane and sevoflurane have beneficial effects in decreasing morbidity in cardiac surgical patients. Studies in animal models have indicated that reactive oxygen and nitrogen species probably play a role in mediating these effects. However, data from human studies are scarce and the differential effect of sevoflurane vs. isoflurane on reactive oxygen species (ROS) and reactive nitrogen species (RNS) has not been studied extensively.

Randomized clinical control trial comparing preconditioning effects of volatile agents isoflurane and sevoflurane when administered during coronary artery bypass surgeries on cardiopulmonary bypass (CPB). Serum samples were collected at 3 time points before induction, after cross clamp release and one hour after separation from CPB. Levels of oxidative stress markers and nitric oxide were analyzed in these samples.

Hemodynamic indices, cardio-pulmonary bypass duration, and ICU stay were similar between the groups.
