RESUMEN Objetivo: Comparar las medidas de gasto cardiaco por ecocardiograf ía transtorácica y por catéter arterial pulmonar en pacientes en ventilación mecánica con presión positiva al final de la espiración elevada. Evaluar el efecto de la insuficiencia tricúspide. Métodos: Se estudiaron 16 pacientes en ventilación mecánica. El gasto cardiaco se midió con el catéter arterial pulmonar y por ecocardiografía transtorácica. Las medidas se realizaron en diferentes niveles de presión positiva al final de la espiraci&o...

We examined the correlates of R-V/A and traditional echocardiographic indices of RVSD, over the spectrum of pulmonary hypertension and tertiles of mean pulmonary artery pressures (PAPm). Methods In 2016–2017, we studied 81 consecutive patients for heart transplant/advanced heart failure. Inclusion criteria were NIDCM, reduced ejection fraction (≤40%) and sinus rhythm. R-V/A was computed as the RV/pulmonary elastances ratio (R-Elv/P-Ea), derived from a combined right heart catheterization/transthoracic- echocardiographic assessment [right heart catheterization/transthoracic-echocardiographic (RHC/TTE)]. Results...

Current clinical guidelines1,2 recommend the use of intraoperative transesophageal echocardiography (TEE) in coronary artery bypass grafting (CABG) without valvular disease or life-threatening hemodynamics is a reasonable indication. Following the abandonment of the pulmonary artery catheter,3,4 TEE has become an attractive monitoring modality during cardiac anesthesia. However, the supporting evidence for routine use of TEE in uncomplicated CABG is weak, and its benefits in this setting require further evaluation.

The clinical utility of echocardiography for the diagnosis of pulmonary vascular disease (PVD) in former preterm infants with bronchopulmonary dysplasia (BPD) is not established. Elevated pulmonary vascular resistance (PVR) rather than pulmonary artery pressure (PAP) is the hallmark of PVD. We evaluated the utility of echocardiography in infants with BPD in diagnosing pulmonary hypertension and PVD (PVR>3 Wood units  × m2) assessed by cardiac catheterization.

Publication date: Available online 10 January 2020Source: Journal of Cardiology CasesAuthor(s): Kota Kawada, Hirofumi Saiki, Manabu Kemmochi, Seiko Kuwata, Manabu Takanashi, Kagami Miyaji, Hideaki SenzakiAbstractIsolated unilateral absence of the pulmonary artery (UAPA) is a congenital anomaly where involution of the extrapulmonary PA is insufficient and the intrapulmonary PA is only fed by the ductus arteriosus. Affected lung disorder causes complications years after ductus closure; thus, early diagnosis is of importance to avoid these complications. Here, we present the case of a male infant who was admitted to the neona...

Authors: Toroghi HM, Lo KB, Ziccardi MR, Horn B, Kanjanahattakij N, Malik E, Penalver J, Rangaswami J, Gupta S, Amanullah A Abstract Worsening renal function in patients with heart failure with preserved ejection fraction is associated with poor outcomes. Pulmonary arterial capacitance is a novel right heart catheterization derived hemodynamic metric representing pulmonary arterial tree distensibility and right ventricle afterload. Given the strong association between heart failure, pulmonary hypertension, and kidney function, the goal of this study is to investigate the correlation between Pulmonary arterial capac...

Authors: Meoli DF, Clark DE, Davogustto G, Su YR, Brittain EL, Hemnes AR, Monahan K Abstract PURPOSE: Transpulmonary biomarkers may provide insight into pulmonary hypertension (PH) pathophysiology, but require cardiac catheterization. We investigated whether the peripheral arterial/venous ratio (PR) could substitute for the transpulmonary ratio (TPR). MATERIALS AND METHODS: Blood from the pulmonary artery (PA), pulmonary arterial wedge (PAW), peripheral venous, and peripheral arterial positions was analyzed for ET-1, NT-pro-BNP, and cAMP levels in subjects with no PH (n = 18) and PH due to left he...

AbstractPulmonary arterial hypertension (PAH) related to left-to-right shunt can progress to Eisenmenger syndrome, a serious and fatal disease that is not yet curable. This pilot study considered stem cell injection as a new treatment modality in persistent pulmonary hypertension after the correction of a congenital heart defect. Three patients with persistent pulmonary hypertension after ventricular septal defect repair were included in this pilot study for a clinical trial. Mononuclear stem cells derived from patients ’ bone marrow specimens were injected into the right and left pulmonary arteries via cardiac cathe...

CONCLUSIONS: Contrast agent travel time was mainly influenced by left- and right-ventricular function but prediction models poorly fitted the data. Thus, 3-dimensional PV angiography prior to PV ablation procedures necessitates real-time assessment, with visual determination of individual contrast agent passage time to ensure consistently high CMR image quality.

ConclusionImage intensification may decrease malposition rates and mechanical complications associated with difficult central venous catheterisation. Further research comparing the safety and efficiency of ultrasound-guided and fluoroscopy-guided CVC insertion should be contemplated.
