Thromboembolic Pulmonary Hypertension

Objective: The aim of this retrospective study was to review and report short-term and mid-term outcomes of pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension at our institute in the recent 2 years and to describe perfusion strategy. Methods: A total of 58 consecutive patients with chronic thromboembolic pulmonary hypertension underwent pulmonary endarterectomy under deep hypothermia circulatory arrest with an established perfusion practice between November 2015 and December 2017. Peri-operative data and patients’ outcome were retrospectively analyzed. Results: Mean pulmonary artery pressure was decreased (49 (40-56) mmHg vs 27 (20-31) mmHg, p < 0.001), and pulmonary vascular resistance (724 (538-1108) vs 206 (141-284) dyn second cm−5, p < 0.001) improved significantly after surgery. In-hospital mortality was 1.7% and postoperative complication rate was 27.6%. Antipsychotic medication of olanzapine was prescribed for 36 patients (62.1%), which was independently related to total deep hypothermic circulatory arrest time, postoperative blood potassium concentration, and hematocrit. The majority of patients recovered uneventfully with good mid-term cardiac function (New York Heart Association I-II: 98.1%) and neurological outcome (Glasgow Outcome Scale—Extended Upper Good Recovery: 74.1% and Lower Good Recovery: 20.3%). Mid-term neurological outcome was associated with post–pulmonary endarterectomy antipsychotic medication. Conclusion: Short-term and mid-term outcome after pulmonary endarterectomy was comparable to high-volume centers. Incidence of post–pulmonary endarterectomy delirium was relatively high and associated with mid-term neurological outcome. Total deep hypothermic circulatory arrest time, postoperative blood potassium concentration, and hematocrit were independent risk factors of postoperative olanzapine medication. More efforts and further research are required to optimize the neuroprotection of perfusion practice.

Thromboembolic Pulmonary Hypertension

Pulmonary endarterectomy (PEA) is the treatment of choice to relieve pulmonary artery obstruction in patients with chronic thromboembolic pulmonary hypertension (CTEPH). It is a complex surgical procedure with a simple principle: removal of obstructive thromboembolic material from the pulmonary arteries in order to reduce pulmonary vascular resistance, relieve pulmonary hypertension (PH) and alleviate right ventricular dysfunction. In the majority of patients there is symptomatic and prognostic benefit. However, not all patients with CTEPH are suitable for treatment with PEA. Operability assessment is not always easy, being largely subjective and based on experience. It is therefore important that all patients are referred to an experienced CTEPH centre for careful evaluation of suitability for surgery. The most common reason for inoperability is distal vasculopathy accounting for a high proportion of the vascular resistance. Surgery requires cardiopulmonary bypass and periods of deep hypothermic circulatory arrest. Complications include reperfusion lung injury and persistent PH. However, with careful patient selection, surgical technique and post-operative management, PEA is a highly effective treatment with mortality rates <5% at experienced centres. Patients who are unsuitable for surgery may be candidates for medical therapy.

Abstract Background Acute kidney injury (AKI) is a major postoperative morbidity of patients undergoing cardiac surgery and has a negative effect on prognosis. The kidney outcomes after pulmonary endarterectomy (PEA) have not yet been reported; However, several perioperative characteristics of PEA may induce postoperative AKI. The objective of our study was to identify the incidence and risk factors for postoperative AKI and its association with short-term outcomes. Methods This was a single-center, retrospective, observational, cohort study. Assessments of AKI diagnosis was executed based on the Kidney Disease Improving Global Outcomes (KDIGO) criteria. Results A total of 123 consecutive patients who underwent PEA between 2014 and 2018 were included. The incidence of postoperative AKI was 45% in the study population. Stage 3 AKI was associated with worse short-term outcomes and 90-day mortality (p < 0.001, p = 0.002, respectively). The independent predictors of postoperative AKI were the preoperative platelet count (OR 0.992; 95%CI 0.984–0.999; P = 0.022), preoperative hemoglobin concentration (OR 0.969; 95%CI 0.946–0.993; P = 0.01) and deep hypothermic circulatory arrest (DHCA) time (OR 1.197; 95%CI 1.052–1.362; P = 0.006) in the multivariate analysis. Conclusion The incidence of postoperative AKI was relatively high after PEA compared with other types of cardiothoracic surgeries. The preoperative platelet count, preoperative hemoglobin concentration and DHCA duration were modifiable predictors of AKI, and patients may benefit from some low-risk, low-cost perioperative measures.

Abstract Objective Pulmonary endarterectomy (PEA) is the only causative, but demanding treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH). We analyzed our results with PEA to evaluate the learning curve. Methods Consecutive 499 patients who underwent PEA between 1995 and 2014 were divided into two groups according to the temporal order: early cohort (n = 200, December 1995–March 2006), and late cohort (n = 299, March 2006–December 2014). We assessed perioperative outcomes after PEA as compared between the early and the late cohort also in propensity-score–matched cohorts. Results Age at the surgery was older in the late cohort (p = 0.042). Preoperative mean pulmonary artery pressure (mPAP) was 46.8 ± 11.0 mm Hg in the early cohort and 43.5 ± 112.7 mm Hg in the late cohort (p = 0.0035). The in-hospital mortality in the early and late cohorts was 14.0% (28/200) and 4.7% (14/299), respectively (p = 0.00030). The duration of circulatory arrest (CA) became much shorter in the late cohort (42.0 ± 20.5 min in the early and 24.2 ± 11.6 min in the late cohort, respectively, p < .0001). In matched cohorts, the in-hospital mortality showed no significant difference (8.7% in the early cohort and 5.2% in the late cohort, < 0.0001). The CA duration, however, was still shorter in the late cohort (p <0.0001). Conclusions Over time, older patients have been accepted for surgery, more patients were operated for lesser severity of CTEPH. Duration of CA and mortality decreased even beyond the first 200 patients, indicating a long learning curve.

Thromboembolic Pulmonary Hypertension

Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious complication of unresolved pulmonary embolism. CTEPH is a potentially curable disease and the treatment of choice is pulmonary endarterectomy (PEA) with complete clearance of pulmonary arteries being the principle of surgery. The surgery is performed under circulatory arrest during cardiopulmonary bypass circulation. We report 3 cases of CTEPH in 2018-2019 at department of cardiothoracic surgery, Rehman Medical Institute, Peshawar. They were detected by echocardiography (TTE) and confirmed by CTPA. Pulmonary endarterectomy was performed with good peri-operative outcome and significant improvement of hemodynamics.

Cytokine Stimulation

Leptin is a hormone that regulates food intake. During inflammatory status, leptin may contribute to the anorexia and cachexia of infection. Pulmonary endarterectomy was used as a model of non-infectious cytokine network hyperstimulation. Leptin and soluble leptin receptor (SLR) were compared with evolution of cortisol and inflammatory cytokines in twenty-two patients with chronic thromboembolic pulmonary hypertension treated with pulmonary endarterectomy using cardiopulmonary bypass (CBP) and deep hypothermic circulatory arrest (DHCA). Leptin, SLR, cortisol, IL-1β, IL-6, IL-8, and TNFα concentrations in arterial blood were measured before/after sternotomy, last DHCA, separation from bypass, 12, 18, 24, 36, and 48 h after sternotomy. Mean duration of CPB was 338.2 min.; mean circulatory arrest time 39.9 min. The initial decline of leptin, SLR, TNFα, IL-6, and IL-8 was followed by an increase culminating 6- 24 h after sternotomy. Leptin peak levels were detected 24 h after sternotomy (28.0 ng/ml, 21.9-37.6). IL-6 culminated after separation from CPB, IL-8 was highest 12 h after sternotomy. Leptin concentrations correlated with IL-6 (r=0.82), and TNFα (r=0.73). Large cardiovascular surgery caused a significant increase in serum leptin, indicating its acute regulation by stress factors. This effect may be secondary to the inflammatory response mediated via cytokine stimulation. Correlation between leptin and IL-6 indicates the role of IL-6 in leptin induction.
