Perioperative pulmonary hypertension

Background Stroke is a prevalent ailment that impacts a substantial number of individuals globally, resulting in both physical impairment and mortality. One of its major causes is carotid artery stenosis. The symptoms and degree of stenosis are key indications for carotid endarterectomy (CEA). In this study, we highlight the indications and outcomes of carotid endarterectomy in our center. Methods This is a descriptive, retrospective, observational study. Data of patients who underwent CEA at Glan Clwyd Hospital from January 2018 to January 2023 was retrieved...

OBJECTIVES: In patients with left heart disease and severe aortic stenosis (AS), pulmonary hypertension (PH) is a common comorbidity and predictor of poor prognosis. Untreated AS aggravates PH leading to an increased right ventricular afterload and, in line to right ventricular dysfunction. The surgical benefit of aortic valve replacement (AVR) in elderly patients with severe AS and PH could be limited due to the multiple comorbidities and poor outcomes. Therefore, we purposed to investigate the impact of PH on short-term outcomes in patients with moderate to severe AS who underwent surgical AVR in our heart center...

Commonly identified risk factors for perioperative cardiac arrest in pediatric-aged patients include cardiac surgery, younger age, comorbid conditions including pulmonary hypertension and cyanotic congenital heart disease, and emergency surgery. Although medication-related etiologies formerly predominated, the elimination of halothane from anesthetic care has resulted in a shift in etiology to hemodynamic events related to blood loss or hyperkalemia associated with the rapid administration of blood products...

OBJECTIVES: Left ventricular (LV) diastolic function strongly predicts outcomes after cardiac surgery, but there is no consensus about appropriate intraoperative assessment. Recently, intraoperative diastolic strain-based measurements assessed by transesophageal echocardiography (TEE) have shown a strong correlation with LV relaxation, compliance, and filling, but there are no reports about evaluation through the entire perioperative period. Therefore, the authors describe the intraoperative course of this novel assessment technique in patients who underwent coronary artery bypass grafting, and compare it with conventional echocardiographic measures and common grading algorithms of LV diastolic dysfunction (LVDD)...

OBJECTIVES: Mitral annular calcification remains a formidable lesion in cardiac surgery with significant perioperative morbidity and mortality, particularly when en bloc annular decalcification is implemented. Respect strategies and hybrid approaches have provided safe alternatives. We report the short-term results of our institution's experience with mitral valve replacement in patients with extensive annular calcification. METHODS: This is a retrospective review of 72 consecutive patients with extensive annular calcification who underwent open surgical mitral valve replacement from January 1, 2013, to September 31, 2022...

BACKGROUND: Pulmonary arterial hypertension (PAH) in pregnancy is one of the major obstetric complications and is considered a contraindication to pregnancy as it is classified as a class IV risk in the revised risk classification of pregnancy by the World Health Organisation. Pregnancy, with its adaptive and expectant mechanical and hormonal changes, negatively affects the cardiopulmonary circulation in pregnant women. Do patients with repaired simple congenital heart disease (CHD) develop other pulmonary and cardiac complications during pregnancy? Can pregnant women with sudden pulmonary hypertension be treated and managed in time? In this paper, we present a case of a 39-year-old woman who underwent cesarean section at 33 wk' gestation and developed PAH secondary to repaired simple CHD...

Over the past decade, the field of solid organ transplantation has undergone significant changes, with some of the most notable advancements occurring in liver transplantation. Recent years have seen substantial progress in preoperative patient optimization protocols, anesthesia monitoring, coagulation management, and fluid management, among other areas. These improvements have led to excellent perioperative outcomes for all surgical patients, including those undergoing liver transplantation. In the last few decades, there have been numerous publications in the field of liver transplantation, but controversies related to perioperative management of liver transplant recipients persist...

BACKGROUND: Protamine administration was shown to reduce bleeding after carotid surgery but the role of protamine during peripheral vascular interventions (PVIs) remains unknown. This study evaluates the trend and outcomes of protamine use in the Vascular Quality Initiative (VQI). Our hypothesis is that the use of protamine is associated with decreased bleeding after PVI. METHODS: Patients undergoing elective PVI in the VQI (2016-2020) for peripheral arterial disease were reviewed and the utilization trend for protamine was described...

BACKGROUND: Postoperative pulmonary complications (PPC) include any complication that affects the respiratory system after anesthesia and surgery and are a significant cause of postoperative mortality and morbidity. OBJECTIVES: To describe the risk factors for immediate postoperative pulmonary complications after appendectomy under general anesthesia and to determine if rapid sequence induction decreases the risk. DESIGN AND SETTING: A retrospective analysis of perioperative medical records of patients who underwent appendectomy under general anesthesia over a year, from January 1st, 2014, to December 31st, 2014, at Hamad General Hospital, Doha, Qatar, was done...

At our institution, we occasionally see pregnant patients in the later stages of pregnancy who present with severe pulmonary arterial hypertension caused by congenital heart disease. The physiological changes in pregnancy may worsen the cardiovascular status leading to heart failure which is associated with a high incidence of morbidity and mortality. A scheduled caesarean section in such patients ensures delivery in a controlled environment, avoiding prolonged labour, which is detrimental. Perioperative complications that may worsen pulmonary arterial hypertension should be prevented...

BACKGROUND: Liver resection offers substantial advantages over open liver resection (OLR) for patients with hepatocellular carcinoma (HCC) in terms of reduced intraoperative blood loss and morbidity. However, there is limited evidence comparing the indications and perioperative outcomes with the open versus laparoscopic approach for resection. This study aimed to compare postoperative outcomes between patients undergoing laparoscopic liver resection (LLR) and OLR for HCC with clinically significant portal hypertension (CSPH)...

Atrial fibrillation (AF) is the most commonly sustained arrhythmia after pulmonary resection, which has been shown to predict higher hospital morbidity and mortality. The lack of strong evidence-based medical evidence makes doctors have very few options for medications to prevent new-onset AF following thoracic surgery. Magnesium can prevent perioperative AF in patients undergoing cardiac surgery. However, this has not yet been fully studied in patients undergoing non-cardiac thoracic surgery, which is the aim of this study...

BACKGROUND: Systemic sclerosis (SSc) is a rare autoimmune disorder with pathological manifestations affecting multiple organ systems. Few studies have examined perioperative outcomes in patients with this disorder. The primary aim of this retrospective single-center comparative cohort analysis was to estimate the incidence of select perioperative complications in a population of SSc patients. In an exploratory analysis, we analyzed the relationship between SSc and susceptibility to select perioperative complications when treated at a large quaternary-care institution...

Lung transplantation is the only therapy for patients with end-stage lung disease. In advanced lung diseases such as cystic fibrosis (CF), life expectancy increases, and it is important to recognize extrapulmonary comorbidities. Cardiovascular involvement, including pulmonary hypertension, right-heart failure, and myocardial dysfunction, are manifest in the late stages of CF disease. Besides right-heart failure, left-heart dysfunction seems to be underestimated. Therefore, an optimal anesthesia and surgical management risk evaluation in this high-risk patient population is mandatory, especially concerning the perioperative use of mechanical circulatory support...

The goal of this article is to provide an up-to-date and comprehensive review of the current perioperative anesthetic management of pediatric patients with congenital heart disease (CHD) undergoing non-cardiac surgery. This report discusses a case of a nine-month-old female with Tetralogy of Fallot who was scheduled for non-cardiac surgery for anorectal malformation stage 1 and stage 2 repair. This case study discusses how to adjust perioperative anesthesia care in cases of left-to-right shunt, right-to-left shunt, and complex cardiac disease...

Caesarean section has risks of bleeding, infection and thromboembolism, and neuroendocrine-metabolic, and inflammatory-immune responses that may worsen outcomes in patients with preeclampsia. There is little research examining perioperative, as opposed to peripartum, outcomes in patients with preeclampsia. We conducted a single-centrecentre retrospective cohort study of perioperative patients with preeclampsia over an eight-month period to determine the rate of perioperative complication. Seventy-two patients were included...

PURPOSE OF REVIEW: This review aims to summarize recent changes in the cardiac evaluation of adult liver transplant candidates. Over the last several years, there have been significant advances in the use of coronary computed tomography angiography (CCTA) with and without fractional flow reserve (FFR) and increasingly widespread availability of coronary calcium scoring for risk stratification for obstructive coronary artery disease. This has led to novel strategies for risk stratification in cirrhotic patients being considered for liver transplant and an updated American Heart Association (AHA) position paper on the evaluation of liver and kidney transplant candidates...

BACKGROUND: Transurethral resection of bladder tumor (TURBT) is associated with perioperative morbidity of 5% to 10%, which can lead to unplanned readmissions. In this study, we aimed to identify the factors that lead to an increased risk of unplanned readmissions within 30 days of primary TURBT. MATERIALS AND METHODS: A retrospective study was conducted to identify patients who underwent primary TURBT at our institute from 2011 to 2019. Clinical and demographic factors, history of smoking, antiplatelet drugs intake, comorbidities, tumor size (<3 or >3 cm), multifocality, and histopathological type were abstracted...

BACKGROUND: Patients with paraplegia often experience chronic shoulder pain due to overuse. We sought to determine if these patients have an increased prevalence of perioperative complications and higher rates of re-admissions and rotator cuff re-tears relative to able-bodied controls following rotator cuff repair (RCR). METHODS: We queried the NRD (2011-2018) to identify all patients undergoing primary RCR (n = 34,451) and identified cohorts of matched paraplegic and non-paraplegic patients (n = 194 each)...

BACKGROUND: Pulmonary endarterectomy (PEA) is the only definitive and potentially curative therapy for chronic thromboembolic pulmonary hypertension (CTEPH), associated with impressive improvements in symptoms and haemodynamics. However, it is only offered at a few centres in South Africa. The characteristics and outcomes of patients undergoing PEA in Cape Town have not been reported previously. OBJECTIVES: To assess the difference in World Health Organization functional class (WHO-FC) before and at least 6 weeks after surgery...
