Published: January 2024

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.

Published: January 2024

ABSTRACT

Background:
Antibiotics resistance is an paramount threat affecting the whole world but nowhere situation is as gloomy as in India. No study till date regarding epidemiology of hospital acquired infections in coronary care units(CCU) and cardiology wards from India. From Indian perspective it is the first observational study to analyse microbiological profile and antibiotic resistance in CCU. The purpose of this observational study is to explore the epidemiology and importance of infections in CCU patients.

Methodology:
After ethics committee approval, the records of all patients who were admitted in coronary care units, adult and pediatric cardiology wards surgery between January 2020 and December 2021 were reviewed retrospectively. The type of organism,source of infection ,age wise distribution and seasonal variability among patients who developed hospital acquired infection (HAI) were determined.

Results:
271 patients developed microbiologically documented HAI during from January 2020 to December 2021. Maximum number of organisms(78/271 28.78%) are isolated from urinary samples ,followed by blood stream(60/271 22.14%) and Endotracheal tube (54/271 19.92%). Acinetobacter baumanii (53/271, 19.5%) being the most common isolate among all the samples taken . Acinetobacter was the most frequent pathogens isolated in patients with LRTI and blood stream infection while E. coli was from urinary tract infection . In the adult population, infection with E. coli(24.6%) is the most common followed by Klebsiella pneumoniae (12.8%) and Acinetobacter baumanii (10.1%). In the pediatric population Acinetobacter baumanii (38.6%%) is the most common followed by Klebsiella pneumoniae (20.5%) and Methicillin Resistant Staphylococcus aureus, MRSA (6.8%). Commonly used antibiotics eg ciprofloxacin,ceftazidime and amikacin were found to be resistant against the top three isolates.

Conclusion:
Urinary tract was the most common site of infection and Gram-negative bacilli, the most common pathogens in adult as well as pediatric population. Antibiotic resistance was maximum with commonly isolated microorganisms.
When is the Ideal Time to Calculate the Vasoactive Inotropic Score as a Predictor of Mortality and Morbidity in Cardiac Surgery? A Retrospective Study
Authors: Keleş Bilge Olgun , Yılmaz Elvan Tekir , Altınbaş Ali , Zengin Sabür , Yılmaz Seyhan 
Published: January 2024

ABSTRACT

Introduction:
The aim of this study was to evaluate the prediction of vasoactive inotropic score (VIS) on early mortality and morbidity after coronary artery bypass grafting (CABG) and to determine the ideal time for score calculation.

Materials and Methods:
The study included patients who underwent isolated on-pump CABG surgery between November 2021 and November 2022. Pre, intra, and postoperative data were obtained by retrospective chart review. The final VIS value in the operating room (VISintra) and the highest VIS value in the first 24 hours in the intensive care unit (VISmax) were calculated. The patients were divided into two groups; Group 1 who developed early postoperative morbidity and mortality and Group 2 who did not. And the data were analyzed by groups.

Results:
A total of 221 patients with a mean age of 63.49 ± 9.96 years were evaluated and 73 (33%) were in Group 1. The cut-off value for VISintra was determined to be 6.20, VISmax was 6,05. VISintra and VISmax values were significantly higher in the poor outcome group. Multivariate analysis showed that only VISmax value was an independent variable on mortality-morbidity.

Conclusions:
Our results imply that the vasoactive inotropic score is an easy and inexpensive score to calculate and can be used as a specific scoring system to predict poor early outcomes in CABG patients. According to statistical analyses, the most predictive time among VIS measurements was VISmax, the highest value calculated in the ICU in the first 24 hours postoperatively.
Congenital Sub-Mitral Aneurysm: Anesthetics and Surgical Management
Authors: Kalbande Jitendra V. , Singha Subrata S. , Bodhey Narendra , Sahani Preetam 
Published: January 2024

ABSTRACT
A sub-mitral left ventricular aneurysm is a rare condition. It is a congenital outpouching of the left ventricular wall, invariably occurring adjacent to the posterior mitral leaflet. Sub-mitral aneurysm (SMA) has usually been reported as a consequence of myocardial ischemia (MI), rheumatic heart disease, tuberculosis, and infective endocarditis. Nevertheless, there have been few case reports of congenital SMA in India. It usually presents with symptoms of heart failure. We report a rare case of congenital SMA in a 27-year-old young Indian and its successful management through a trans-aneurysmal approach.

Published: January 2024

ABSTRACT
The occurrence of pulmonary artery thrombus in association with rheumatic mitral stenosis is a rare complication. Pulmonary artery thrombus formation may worsen pulmonary artery pressures, and this may precipitate acute right heart failure. The possible mechanisms behind pulmonary artery thrombus formation during mitral valve replacement surgery could be acute coagulopathy following surgery, the presence of chronic pulmonary thromboembolism, or chronic atrial fibrillation. We report an unusual case of pulmonary artery thrombus in a patient with rheumatic MS which was diagnosed with transoesophageal echocardiography after MVR.

Published: January 2024

ABSTRACT
Cardiac surgeries often result in significant postoperative pain, leading to considerable use of opioids for pain management. However, excessive opioid use can lead to undesirable side effects and chronic opioid use. This systematic review and meta-analysis aimed to evaluate whether preoperative intrathecal morphine could reduce postoperative opioid consumption in patients undergoing cardiac surgery requiring sternotomy. We conducted a systematic search of Cochrane, EMBASE, and MEDLINE databases from inception to May 2022 for randomized controlled trials that evaluated the use of intrathecal morphine in patients undergoing cardiac surgery. Studies that evaluated intrathecal administration of other opioids or combinations of medications were excluded. The primary outcome was postoperative morphine consumption at 24 h. Secondary outcomes included time to extubation and hospital length of stay. The final analysis included ten randomized controlled trials, with a total of 402 patients. The results showed that postoperative morphine consumption at 24 h was significantly lower in the intervention group (standardized mean difference -1.43 [-2.12, -0.74], 95% CI, P < 0.0001). There were no significant differences in time to extubation and hospital length of stay. Our meta-analysis concluded that preoperative intrathecal morphine is associated with lower postoperative morphine consumption at 24 h following cardiac surgeries, without prolonging the time to extubation. The use of preoperative intrathecal morphine can be considered part of a multimodal analgesic and opioid-sparing strategy in patients undergoing cardiac surgery.
Perioperative Challenges and Outcome After Surgical Correction of Post-myocardial Infarction Ventricular Septal Rupture: A Retrospective Single Center Study
Authors: Bangal Kedar 
Published: January 2024

ABSTRACT

Background:
Ventricular septal rupture (VSR) is a rare but grave complication of acute myocardial infarction (AMI). It is a mechanical complication of myocardial infarction where patients may present either in a compensated state or in cardiogenic shock. The aim of the study is to determine the in-hospital mortality. The study also aims to identify the predictors of outcomes (in-hospital mortality, vasoactive inotrope score (VIS), duration of ICU stay and mechanical ventilation in the postoperative period) and compare the clinical and surgical parameters between survivors and non-survivors.

Methods:
This is a retrospective study. The data of 90 patients was collected from the medical records and the data comprising of 13 patients who underwent VSR closure by single patch technique, or septal occluder, and those who expired before receiving the treatment, was excluded. The data of 77 patients diagnosed with post-AMI VSR and who underwent surgical closure of VSR by double patch technique was included in this study. Clinical findings and echocardiography parameters were recorded from the perioperative period. The statistical software used was SPSS version 27. The primary outcome was determining the in-hospital mortality. The secondary outcome was identifying the clinical parameters that are significantly more in the non-survivors, and the factors predicting the in-hopsital mortality and morbidity (increased duration of ICU stay, and of mechanical ventilation, postoperative requirement of high doses of vasopressors and inotropes). Subgroup analysis was done to identify the relation of various clinical parameters with the postoperative complications. The factors predicting the in-hospital mortality were illustrated by a forest plot.

Results:
The mean age of the patients was 60.35 (±9.9) years, 56 (72.7%) were males, and 21 (27.3%) were females. Requirement of mechanical ventilation preoperatively (OR 3.92 [CI 2.91-6.96]), cardiogenic shock at presentation (OR 4 [CI 2.33 – 6.85]), requirement of IABP (OR 2.05 [CI 1.38-3.94]), were predictors of mortality. The apical location of VSR had been favorable for survival. The EUROScore II at presentation correlated with the postoperative VIS (level of significance [LS] 0.0011, R 0.36. The in-hospital mortality in this study was 33.76%.

Conclusion:
The in-hospital mortality of VSR is 33.76%. Cardiogenic shock at presentation, non-apical site of VSR, preoperative requirement of mechanical ventilation, high VIS preoperatively, perioperative utilization of IABP, prolonged CPB time, postoperative duration of mechanical ventilation, and high postoperative VIS were the factors associated with increased odds of in-hospital mortality.
