Abstract BackgroundTricuspid Regurgitation (TR) gradient on echocardiogram is used to approximate pulmonary artery pressure (PAP) on echocardiography. A common dilemma is encountered when PAP measurement is indeterminate due to poor TR signal. We hypothesized that patients with poor TR signal would be unlikely to have pulmonary hypertension (PH) on right heart catheterization (RHC). MethodsWe performed a retrospective analysis of 141 patients who underwent RHC and had a corresponding echocardiogram showing poor TR signal within 2 months of RHC. A cutoff of 25 mm Hg was used as the upper limit of normal to define PH. ResultsFifty percent of patients had mean PAP (mPAP) greater than 25 mm Hg. 82% of values were 35 mm Hg or below. ConclusionsPoor TR signal does not rule out PH but may indicate lower likelihood of severe PH.

Abstract Background Doppler echocardiography is the most widespread and well-recognized technique for the screening of patients with pulmonary hypertension (PH). When tricuspid regurgitation peak velocity (TRPV) ≥3.4 m/s, right heart catheterization is requested to confirm mean pulmonary artery pressure >25 mm Hg. In the proceedings from the 6th world symposium on pulmonary arterial hypertension recently released, the new definition of PH has been lowered to mean pulmonary artery pressure > 20 mm Hg. Purpose The purpose of our work was twofold : i) to determine a new cut-off value for TRPV to accommodate the new hemodynamic definition of PH, ii) to investigate the impact on the demand of right heart catheterization (RHC) from our echo CORE lab. Methods We extracted and analyzed both the haemodynamic and echocardiographic records of 130 patients who underwent investigations the same day. Tricuspid regurgitation peak velocity was measured in apical-4 chamber view using continuous-wave doppler modality and compared to mean pulmonary artery pressure recorded from fluid-filled catheter. Results Tricuspid regurgitation peak velocity has a weak correlation with mean pulmonary pressure (y = 9.2x-2.2, r² = 0.22, p < 0.01). Targeting a mean pulmonary pressure on right heart catheterization of 20 mm Hg for the definition of PH, receiver operating characteristic curve analysis demonstrated a good association between TRPV and PH diagnosis (area under the curve, 0.78 ; p < 0.001). The cut-off value obtained for TRPV was 3.0 m/s (Se = 0.78, Sp = 0.37). From 01/01/18 to 31/12/18, 2539 out of 6215 had TRPV recorded from which 283 had TRPV ≥ 3.0 m/s (24,1%) and 615 had TRPV ≥ 3.4 m/s (11,1%). When applied to a community population the new TRPV cutoff > 3m/s used as surrogate for mean pulmonary artery pressure > 20 mm Hg may produce a 111% increase of right heart catheterization demand. Conclusions The new definition of pulmonary hypertension (invasive mean pulmonary artery pressure > 20mm Hg) necessitates revisiting tricuspid regurgitation peak velocity > 3 m/s as a screening test leading to more than twice RHC demand.

Uncommon Condition

Pulmonary hypertension is not an uncommon condition in clinical setting. Pulmonary artery (PA) pressure may increase during anesthesia because of the hypoxia, hypoventilation and acidosis. Keeping these factors constant there are also other possibilities which can increase the PA pressure, for example drugs. Among them ketamine is known to increase PA pressure in adults especially when they have baseline increased PA pressure. In few literatures it is claimed that in children ketamine may be safe even in those with pulmonary hypertension. We are using ketamine as a component of intravenous anesthesia in catheterization lab during right heart catheterization, pressure measurement and saturation evaluation. We thought it was necessary to evaluate the effect to ketamine on pulmonary artery pressure in pediatric patients in our setting. Altogether fifteen children diagnosed with pulmonary hypertension wer anesthetized with ketamine based anesthesia and the pulmonary artery pressure was evaluated in cardiac catheterization laboratory before and after 5, 10 and 15 min of injection of the ketamine (2mg/kg body weight) intravenously. We found in our study only about 6.2% increment in pulmonary artery pressure after 5 minutes of the injection of the ketamine and the pressure came to the pre-injection level at 10 to 15 minutes of the injection In conclusion of this preliminary study with limited number of the cases, ketamine can be used safely without much problems in pulmonary hypertensive children secondary to the increased blood flow to the lungs.

Abstract Introduction Lung transplantation (LT) often requires extracorporeal life support with extracorporeal membrane oxygenation (ECMO) because of several complications (included acute heart failure) during the intervention. Data on predictors of intraoperative ECMO use in these patients are scarce but it is an interesting topic because ECMO support has been linked to worse outcomes after LT. Purpose The main aim of our study is to assess which pre-surgical characteristics of right ventricular (RV) function and data from right heart catheterization (RHC) could help us to anticipate the need of ECMO in LT. Methods We conducted a retrospective observational study of all patients who underwent LT at our institution along 2018. We analysed data from echocardiogram (ECO) and RHC. All subjects underwent transthoracic echocardiography (TTE) according to the latest ASE/EACVI guidelines. Strain analysis was carried out by speckle-tracking echocardiography (QLAB 10.7, Philips). Results We included all 47 patients who underwent LT from January to December of 2018. They were middle age patients (52±11.8 years old) 51.1% men, 61.7% smokers (other cardiovascular risks: diabetes mellitus (8.5%), hypertension (23.4%) or dyslipidaemia (27.7%)). 24 (51%) of them needed intraoperative ECMO. 21 patients (45%) were evaluated by RHC before LT and ECO quality was good enough to evaluate different data in 41 patients (87%). Variables related to ECMO requirement vs non-ECMO use were: mean pulmonary artery pressure (23.1±7.3 vs 16.67±4.9 mmHg, p=0.027), mean transpulonary gradient (16.9±6.6 vs 8.9±3.6 mmHg, p=0.027) and diastolic transpulmonary gradient (9.8±8.1 vs 2.3±4.7 mmHg, p=0.002) from RHC and RV mid cavity diameter (3.4±0.8 vs 2.8±0.6 mm, p=0.001) from ECO. Besides this, free-wall RV longitudinal strain (FWRVLS) showed a tendency to be lower in patients who required ECMO (17.3±4.5% in vs 21.4±4.5%, p=0.072). Conclusion According to our results, RV mid cavity diameter measured by ECO and mean pulmonary artery pressure, mean and diastolic pulmonary gradients measured by RHC are useful tools to predict which patients could require ECMO during LT. FWRVLS showed an interesting tendency of lower values of it in LT using ECMO. This exploratory finding opens an important investigation line about a parameter which could help us to identify patients with subclinical right ventricle dysfunction.
