pulmonary hypertension preoperative management

INTRODUCTION: Although unplanned readmission is a postoperative outcome metric associated with significant morbidity and financial burden, precise assessment tools for its prediction are yet to be developed. The Risk Analysis Index (RAI) could potentially be utilized to help improve prediction unplanned readmission in patients undergoing intracranial tumor resection (ITR). Here we evaluate the predictive accuracy of frailty on 30-day unplanned readmission following ITR using the RAI. METHODS: Data were obtained from the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database...

Aortic dissection (AD) is a severe cardiovascular condition that could have negative consequences. Our study employed a prospective design and examined preoperative, perioperative, and postoperative data to evaluate the effects of gender on various medical conditions. We looked at how gender affected the results of aortic dissection (AD). In contrast to female patients who had more systemic hypertension (p=0.031), male patients had higher rates of hemopericardium (p=0.003), pulmonary hypertension (p=0.039), and hemopericardium (p=0...

BACKGROUND: Right ventricular failure (RVF) is a leading driver of morbidity and death after major cardiac surgery for advanced heart failure, including orthotopic heart transplantation and left ventricular assist device implantation. Inhaled pulmonary-selective vasodilators, such as inhaled epoprostenol (iEPO) and nitric oxide (iNO), are essential therapeutics for the prevention and medical management of postoperative RVF. However, there is limited evidence from clinical trials to guide agent selection despite the significant cost considerations of iNO therapy...

INTRODUCTION: The perioperative management of patients with pulmonary hypertension (PH) undergoing cardiac surgery represents one of the most challenging clinical scenarios. This fact mainly depends on the relationship existing between PH and right ventricular failure (RVF). Levosimendan (LS) is an inodilator that might be an effective agent in the treatment of PH and RVF. The aim of this study was to examine the impact of the duration of cardiopulmonary bypass (CPB) on the therapeutic drug monitoring of LS and to evaluate the effect of preemptive administration of LS on perioperative hemodynamic and echocardiographic parameters in cardiac surgical patients with preexisting PH...

INTRODUCTION: As measured by a right heart catheterization, pulmonary hypertension is an increase in mean pulmonary arterial pressure of more than 25 mmHg at rest or more than 30 mmHg during exercise. Some of the cardiac heart conditions that may develop during pregnancy include severe mitral regurgitation and mild tricuspid regurgitation. Prior to delivery, pregnant patients with pulmonary hypertension and significant multivalvular heart disease need to undergo careful preoperative, multidisciplinary assessment, and anaesthetic planning to maximize cardiac function during the peripartum period and make informed decisions about the delivery mood and anaesthetic technique...

Pulmonary hypertension (PH) is characterized by narrowing small pulmonary arteries, escalating pulmonary vascular resistance, and affecting the entire cardiovascular system. Pulmonary arterial hypertension (PAH) represents a subgroup of PH and typically affects one in 20,000 individuals. When treating individuals with PAH for non-cardiothoracic surgery, anesthetic management strategies should be tailored to the individual's specific needs. This literature review assessed the anesthetic management of PAH in non-cardiothoracic surgery...

OBJECTIVE: To identify potentially modifiable risk factors related to prolonged cardiovascular pharmacological support after weaning from cardiopulmonary bypass (CPB). METHODS: This is a secondary analysis of two prospective cohort study in a specialized cardiac surgery institution in adult patients undergoing cardiac surgery with the use of CPB between August 2016 and July 2017. Prolonged cardiovascular pharmacological support was defined by the need for at least one vasopressor or one inotropic agent 24 hours after separation from CPB...

OBJECTIVE: Adverse perioperative events and discharge medications both have the potential to impact survival following endovascular abdominal aortic aneurysm repair (EVAR). We hypothesize that variables such as blood loss, reoperation in the same hospital admission, and lack of discharge statin/aspirin have significant effect on long term survival following EVAR. Similarly, other perioperative morbidities, are hypothesized to affect long term mortality. Quantifying the mortality effect of perioperative events and treatment emphasizes to physicians the critical nature of preoperative optimization, case planning, operative execution and postoperative patient management...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is primarily managed by pulmonary thromboendarterectomy (PTE). As advanced surgical techniques permit resection at the segmental and subsegmental level, PTE can now be curative for CTEPH mostly involving the distal pulmonary arteries. METHODS: Between January 2017 and June 2021, consecutive patients undergoing PTE were categorized according to the most proximal level of chronic thrombus resection: Level I (main pulmonary artery), Level II (lobar), Level III (segmental) and Level IV (subsegmental)...

Pulmonary hypertension, defined as an elevation in blood pressure in the pulmonary arteries, is associated with an increased risk of death. The prevalence of pulmonary hypertension is increasing, with an aging population, a rising prevalence of heart and lung disease, and improved pulmonary hypertension survival with targeted therapies. Patients with pulmonary hypertension frequently require noncardiac surgery, although pulmonary hypertension is associated with excess perioperative morbidity and death. This scientific statement provides guidance on the evaluation and management of pulmonary hypertension in patients undergoing noncardiac surgery...

Anesthetists are concerned about the causes and management of hypoxia during one-lung ventilation (OLV). Here, we report a hypoxic case during OLV and video-assisted thoracic surgery (VATS) for pulmonary lobectomy. The preoperative management of hypertension with amlodipine was considered to be responsible for the hypoxia. As a calcium channel blocker, amlodipine may inhibit hypoxic pulmonary vasoconstriction (HPV) and contribute to the reduction of the ventilation/perfusion ratio (or V/Q ratio). The hypoxia efficiently was treated by atropine, where both tracheal effects and the enhancement of HPV through muscarinic receptor blocking may work...

Pulmonary hypertension (PH) is a haemodynamic manifestation of cardiorespiratory and non-cardiorespiratory pathologies. Cardiorespiratory pathologies account for nearly three-fourths of patients with PH. It is now increasingly being recognised due to routine requests for transthoracic echocardiographic examination in the perioperative setting in patients undergoing intermediate- to high-risk non-cardiac surgery. The increased risks of perioperative morbidity and mortality attributed to PH have been widely acknowledged in the literature...

BACKGROUND: Methamphetamine abuse is a serious public health concern and causes various life-threatening disorders including pulmonary arterial hypertension (PAH). Herein, we present the first case report describing the anesthetic management of a patient with methamphetamine-associated PAH (M-A PAH) undergoing laparoscopic cholecystectomy. CASE PRESENTATION: A 34-year-old female with M-A PAH suffered from deterioration of right ventricular (RV) heart failure due to recurrent cholecystitis and was scheduled for laparoscopic cholecystectomy...

INTRODUCTION: Pulmonary hypertension (PHT) is a known risk factor for coronary artery bypass grafting (CABG), though less well understood for valve operations. We hypothesized PHT is associated with lower risk during mitral valve operations compared to CABG. METHODS: Patients undergoing isolated mitral valve or CABG operations (2011-2019) in a regional Society of Thoracic Surgeons (STS) database were stratified by pulmonary artery systolic pressure (PASP). The association of PASP by procedure type was assessed by hierarchical regression modeling, adjusting for STS predicted risk scores...

BACKGROUND: Surgical site infection (SSI) after open spine surgery increases healthcare costs and patient morbidity. Predictive analytics using large databases can be used to develop prediction tools to aid surgeons in identifying high-risk patients and strategies for optimization. The purpose of this study was to develop and validate an SSI risk-assessment score for patients undergoing open spine surgery. METHODS: The Premier Healthcare Database of adult open spine surgery patients ( n  = 157,664; 2,650 SSIs) was used to create an SSI risk scoring system using mixed effects logistic regression modeling...

BACKGROUND: Less invasive monitoring, such as radial arterial pulse contour analysis (ProAQT® sensor), represents an alternative when hemodynamic monitoring is necessary to guide postoperative management and invasive monitoring is not technically feasible. The aim of the study is to evaluate the accuracy of the ProAQT® sensor cardiac output measurements in comparison with Pulmonary Artery Catheter (PAC) during the postoperative course of patients who underwent cardiac surgery with cardiopulmonary bypass...

BACKGROUND: Contemporary nationwide outcomes of gallstone pancreatitis (GSP) managed by cholecystectomy at the index hospitalization are limited. This study aims to define the rate of 30-day morbidity and mortality and identify associated perioperative risk factors in patients undergoing cholecystectomy for GSP. METHODS: Patients from the ACS-NSQIP database with GSP without pancreatic necrosis, who underwent cholecystectomy during the index hospitalization from 2017 to 2019 were selected...

Management of chronic thromboembolic pulmonary hypertension (CTEPH) should be determined by a multidisciplinary team, ideally at a specialized CTEPH referral center. Radiologists contribute to this multidisciplinary process by helping to confirm the diagnosis of CTEPH and delineating the extent of disease, both of which help determine a treatment decision. Preoperative assessment of CTEPH usually employs multiple imaging modalities, including ventilation-perfusion (V/Q) scanning, echocardiography, CT pulmonary angiography (CTPA), and right heart catheterization with pulmonary angiography...

BACKGROUND: Functional tricuspid regurgitation (TR) appears frequently in the presence of left-sided heart valve diseases, combined with symptoms of heart failure, worsens if left untreated, and is associated with poor patient survival. Correct indications for surgery and the choice of suitable technique, which should be based on pathophysiology of disease are of utmost importance to ensure longevity and durability of repair; particularly given the risky nature of reoperations due to residual/recurrent TR...

BACKGROUND: Airway hemorrhage is a known complication of pulmonary thromboendarterectomy (PTE) in patients with chronic thromboembolic pulmonary hypertension. Predisposing factors for postoperative airway hemorrhage have not been well described. The aims of this study were to determine the incidence and outcomes of airway hemorrhage after PTE and to identify potential risk factors. METHODS: This was a retrospective chart review of subjects undergoing PTE between 2015 and 2019...
