Object Ventriculoatrial (VA) shunts inserted for the treatment of hydrocephalus are known to be a risk factor for pulmonary hypertension. The aim of this study was to evaluate the incidence of pulmonary hypertension among adult patients with VA shunts. Methods All patients who had received a VA shunt at one of two institutions between 1985 and 2000 were invited for a cardiopulmonary evaluation. The investigation included a thorough history taking, clinical examination, echocardiography, and pulmonary function testing including diffusing capacity of the lung for carbon monoxide (DLCO). Pulmonary hypertension was defined as systolic pulmonary artery pressure > 35 mm Hg at rest. Results The study group consisted of 86 patients, of whom 38 (44%) could be examined. The patients' mean age was 47.1 ± 18.4 years; the median interval between shunt insertion and cardiopulmonary evaluation was 15 years (range 5–20 years). Of the 38 patients, 20 (53%) had Doppler velocity profiles of tricuspid regurgitation that were adequate for the estimation of pulmonary artery systolic pressure. Doppler-defined pulmonary hypertension was observed in 3 patients (8%), 2 of whom underwent right heart catheterization. Chronic thromboembolic pulmonary hypertension was confirmed in both patients, and medical therapy, including anticoagulation, was started. The VA shunt was removed in both cases and replaced with a different type of device. Pulmonary function tests revealed a restrictive pattern in 15% and typical obstructive findings in 9% of patients. In 30% of patients the DLCO was less than 80% of predicted, and blood gas analysis showed hypoxemia in 6% of patients. No significant differences in pulmonary function tests were noted between the patients with and without echocardiographic evidence of pulmonary hypertension. However, patients with pulmonary hypertension had significantly lower DLCO values. Conclusions The authors detected pulmonary hypertension by using Doppler echocardiography in a significant proportion of patients with VA shunts. It is therefore recommended that practitioners perform regular echocardiography and pulmonary function tests, including single-breath DLCO in these patients to screen for pulmonary hypertension to prevent hazardous late cardiopulmonary complications.

Abstract Background Systemic sclerosis (SSc) is a multi-system connective tissue disease characterized by microvascular damage, inflammation and fibrosis. The aim of our study is to investigate a possible correlation between nailfold videocapillaroscopy patterns and internal organ involvement in patients with early SSc. Methods We enrolled 40 patients with early SSc according to LeRoy criteria and performed echocardiogram, pulmonary function tests (PFTs) and nailfold videocapillaroscopy. Results 20 patients had early pattern and 20 active pattern. A comparative analysis between SSc patients and healthy controls showed an alteration of mitral annular plane systolic excursion (MAPSE) (1.5±0.1 vs 1.7±0.1; p < 0.001), respectively; an increased occurrence of diastolic dysfunction (11/40 vs 0/21; p = 0.01) respectively; a higher values of systolic pulmonary arterial pression (PAPs) (32±6 vs 22±6; p < 0.001) and a higher frequency of patients with pulmonary hypertension (12/40 vs 0/21; p = 0.005) in SSc group. The patients with an active capillaroscopic pattern showed a trend of reduction in MAPSE, diastolic dysfunction, contractility of the right ventricle and pulmonary function tests parameters. We observed a correlation between myocardial and pulmonary vascular damage and between myocardial and pulmonary fibrosis, with lower DLCO value in patients with diastolic dysfunction (64±17 vs 85±9; p < 0.0001). Conclusion A subclinical myocardial damage in these patients may be observed also in the absence of symptoms. In fact, in our study it can be noted that asymptomatic patients present a reduction in the linear myocardial contractility. Furthermore, we observed the presence of grade I diastolic dysfunction in 27.5% of cases, a sign of an initial stiffening of the wall, likely due to a fibrotic damage. In our study linear contractility emerges to be not correlated with the presence of diastolic dysfunction. Such data is very intriguing if we consider that in many studies the resolution of linear contractility with conserved ejection fraction correlated with subendocardial damage induced by microcirculation alterations. The hypothesis is the presence of a double framework at the myocardial level: a vascular damage and the presence of increased inflammation and fibrosis. The presence fibrosis is correlated between the various organs, with the values of DLCO strongly correlating with the presence of diastolic dysfunction; instead DLCO values do not correlate with pulmonary pressure values. The analysis of the capillaroscopic parameters we observed how in the early pattern the presence of vascular damage with MAPSE and PAPs alterations and presence of pulmonary hypertension emerge, while passing from early to active the presence of fibrotic damage becomes evident, the diastolic dysfunction passing from 15% to 40% and DLCO passing from 83% to 75%. The presence of subclinical cardiac and pulmonary damage in patients with systemic sclerosis and that this damage is closely related to the capillaroscopic pattern. Disclosures F. Masini: None. L.

Aim. To evaluate the effectiveness of balloon pulmonary angioplasty (BPA) in patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Materials and methods. Forty patients with inoperable CTEPH were enrolled in this study. The indications were determined by multidisciplinary team. The average age of patients was 53.5 [43; 63] years. In 65% of cases patients had functional class III (according to WHO); the distance in the 6-minute walk test (6MWD) was 327 [280; 400] m; catheterization of the right heart revealed systolic pulmonary artery pressure (SPAP) 82 [64; 100] mm Hg, mean pulmonary artery (mPAP) 48.5 [38; 56] mm Hg, pulmonary vascular resistance (PVR) 784 [525; 1257] dyn·s/cm-5. Each patient underwent 6 BPA. Results and discussion. The effectiveness of BPA was assessed 2 months after the last session. According to the data of right heart catheterization SPAP decreased by 27.3%, mPAP by 26%, PVR by 34.5% from baseline. After all series of BPA echocardiography and magnetic resonance imaging demonstrated reverse remodeling of the right heart. Also significant decrease in the level of BNP by 62%, increasing in 6MWD distance by 39% and improvement of the functional class up to I in 60% cases and up to II in 40% cases were noted. Conclusion. The results of the present study demonstrated a high efficacy of BPA allowing to normalize hemodynamic and clinical parameters, increasing the physical activity. Balloon pulmonary angioplasty is a new highly effective, safe method for treating patients with inoperable CTEPH.

Background Pulmonary endarterectomy is potential curative therapy for chronic thromboembolic pulmonary hypertension patients. Here, we present our experience with pulmonary endarterectomy spanning 17 years and detail our management strategy. Methods This is a single-centre retrospective study conducted on chronic thromboembolic pulmonary hypertension patients who underwent pulmonary endarterectomy at our centre across 17 years. Results Between 2004 and 2020, 591 patients underwent pulmonary endarterectomy. Amongst them 429 (72.4%) were males with a male to female ratio of 2.6:1, the median age was 38 (range, 14–73) years. The median length of hospital stay was 11 days (IQR, 8–16). Extra corporeal membranous oxygenation was used in 82 (13.9%) patients during/after surgery, out of whom 28 (34.1%) survived. There were 70 (11.8%) in-hospital deaths. Female gender ( p < 0.01), pulmonary artery systolic pressure >100 mmHg ( p < 0.05) and use of extra corporeal membrane oxygenation ( p < 0.001) were significant risk factors for in-hospital mortality. The mortality in the first period (2004–2012) was 15.7% which reduced to 9.1% in the later period (2013–2020). The reduction in mortality rate was 42% ( p < 0.05). Following pulmonary endarterectomy, there was a significant reduction in pulmonary artery systolic pressure (86.68 ± 24.38 vs. 39.71 ± 13.13 mmHg; p < 0.001) and improvement in median walk distance as measured by 6-min walk test on follow-up (300 vs. 450 meters; p < 0.001). The median duration of follow-up was 8 months (inter-quartile range: 2–24). Conclusions pulmonary endarterectomy has a learning curve, high pulmonary vascular resistance alone is not a contraindication for surgery. Patients following surgery have improved survival and quality of life.

Introduction Chronic thromboembolic pulmonary hypertension results from the incomplete resolution of the vascular obstruction associated with pulmonary embolism. Symptoms are exertional dyspnoea and fatigue, and over a period of time, right ventricular dysfunction sets in. Pulmonary thromboendarterectomy is an effective surgical remedy for this condition. Our study is an initial post-operative experience of pulmonary thromboendarterectomy and we have also tried to formulate quantitative parameters for the prediction of the post-operative course in patients who are undergoing surgery. Methods Twenty patients with chronic thromboembolic pulmonary hypertension underwent pulmonary thromboendarterectomy between July 2017 and January 2020. Pre-operatively, each patient was subjected to the (i) 6-min walk test, (ii) pre-operative brain natriuretic peptide values and (iii) pulmonary artery systolic pressure. Following the surgery and subsequent discharge, the patients were followed up at intervals of 15 days, 1, 3, 6, 9 months and at 1 year. At one year post-operatively, the same three quantitative tests were performed on each subject. Results Post-operatively, the mean 6-min walk distance was 499.75 m as against 341.35 m pre-operatively ( p < 0.0001). Mean brain natriuretic peptide was 8.69 pm/l as against 47.58 pm/l pre-operatively ( p < 0.0001). Mean pulmonary artery systolic pressure was 22.25 as against 67.1 pre-operatively ( p < 0.0001). Conclusion 6-Min walk test, brain natriuretic peptide and pulmonary artery systolic pressure could be considered as useful predictors of the haemodynamic severity of disease and predict the post-operative outcome.

Background & Purpose Pulmonary hypertension (PH) in sickle cell disease (SCD) is an important risk factor for complications including sudden death. In this study, we aimed to determine the prevalence of PH and correlate the echocardiographic parameters and general laboratory data with markers of hemolysis and serum NT pro-brain natriuretic peptide [BNP] concentrations in Omani SCD patients. Methods A cohort of 163 SCD patients [Mean age 25.4±8.4 years], in steady state was prospectively screened for PH with Doppler echocardiography (defined as a tricuspid regurgitation jet flow velocity of ≥ 2.5 m/sec and/or mean pulmonary artery pressure [mPAP] ≥25 mmHg). After a written informed consent, all patients were investigated with a complete blood count, renal chemistry, hemolytic parameters including LDH, haptoglobin, liver function tests, coagulation studies, HPLC studies including HbS and HbF level estimations, X ray Chest, ECG, ABG, Pulmonary function tests, Pulse oximetry, and Serum NT pro-BNP levels. Results In the evaluable patient cohort of 116 subjects [63 females, 53-males], the prevalence of PH was 5.2%. No statistically significant differences were detected in Hb levels, ECG, chest radiography, pulmonary function tests between patients with and without PH. However, plasma NT pro-BNP levels were significantly correlated with PAH [r=0.934, p<0.000], TRV jet [r=.671, p<0.000], Abnormal ECHO [r=0.672, p<0.000], and direct Bilirubin levels [r=0.278,p<0.009] in SCD patients. Furthermore, in SCD patients with PH, there was a statistically significant increase in plasma NT pro-BNP levels [ p<0.001], ALT [p<0.02], S. Creatinine [p=0.045] and Total bilirubin [p<0.0001] and direct Bilirubin levels [p<0.0001][Table]. Conclusions Serum NT pro-BNP is a strong indicator of PH in SCD patients. Doppler ultrasound echocardiography is a useful initial screen for PH in SCD patients. The correlation between PH and hemolytic markers suggests an implication in the pathogenesis of PH.
