BACKGROUND: Pulmonary artery wedge pressure (PAWP) has been shown to correlate better with left atrial pressure (LAP) than ventricular end-diastolic pressure (VEDP) in acquired heart disease. The correlation between VEDP and PAWP and their performance as surrogates for LAP in Fontan patients is unknown. METHODS: Offline single-beat simultaneous measurement of PAWP and VEDP was performed in 50 adult Fontan patients and non-simultaneous hemodynamic data abstracted for calculation of pulmonary vascular resistance (PVR)...

We have previously developed a simulated cardiovascular physiology model for in-silico testing and validation of novel closed-loop controllers. To date, a detailed model of the right heart and pulmonary circulation was not needed, as previous controllers were not intended for use in patients with cardiac or pulmonary pathology. With new development of controllers for vasopressors, and looking forward, for combined vasopressor-fluid controllers, modeling of right-sided and pulmonary pathology is now relevant to further in-silico validation, so we aimed to expand our existing simulation platform to include these elements...

BACKGROUND: Balloon pulmonary angioplasty (BPA) is an emerging interventional treatment option for chronic thromboembolic pulmonary hypertension (CTEPH). The non-invasive monitoring of CTEPH patients is a clinical challenge. In this study we examined changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients undergoing BPA for inoperable CTEPH and related them to peri-procedural success. METHODS: In this study we analyzed a total of 51 consecutive patients who underwent BPA treatment and completed a 6-month follow-up (6-MFU) between March 2014 and March 2017...

Mild PVR has been shown to increase all-cause and cardiovascular mortality after TAVR, especially in high surgical risk patients. Mechanistic and associative causes, as well imprecise ascertainment have been suggested as underlying etiologies of this association. Ongoing trials with newer valve technologies, broader patient inclusion and more systematic assessment of PVR may provide further insight into the prevalence, causality, and outcome of PVR.

Underactive bladder (UAB) or detrusor underactivity (DU) is a common yet still poorly understood urological problem. In addition to true detrusor failure and neuropathy, the inhibitory effects of detrusor contraction by the striated urethral sphincter and the bladder neck through alpha-adrenergic activity may also play a role in the development of UAB or DU. Treatment of UAB or DU aims to reduce the postvoid residual (PVR) urine volume and increase voiding efficiency, either by spontaneous voiding or abdominal straining...

BACKGROUND: Silicone oil tamponade is more frequently reserved for cases of complex retinal detachment. We describe the effects of different variations in oil ratios with the relatively unknown technique of double oil tamponade. METHODS: Retrospective case note review of nine patients with complex rhegmatogenous retinal detachment (RD). All cases had both superior and inferior breaks, mostly with associated proliferative vitreoretinopathy (PVR). All cases were treated with pars plana vitrectomy (PPV) and a double silicone oil endotamponade (DSOE) of both heavy silicone oil and conventional 'light' silicone oil...

BACKGROUND: Maternal infection is a risk factor for periventricular leukomalacia and cerebral palsy (CP) in neonates. We have previously demonstrated hypomyelination and motor deficits in newborn rabbits, as seen in patients with cerebral palsy, following maternal intrauterine endotoxin administration. This was associated with increased microglial activation, primarily involving the periventricular region (PVR). In this study we hypothesized that maternal intrauterine inflammation leads to a pro-inflammatory environment in the PVR that is associated with microglial activation in the first 2 postnatal weeks...

Pulmonary valve replacement (PVR) in patients with repaired tetralogy of Fallot (rTOF-TAP) is often based on cardiac MRI (CMR) right ventricular (RV) volumes indexed to body surface area (BSA). Weight extremes result in increased patient morbidity and affect indexed measurements. We hypothesized that patients with rTOF-TAP at extremes of weight have (1) over- or underestimated indexed volumes and (2) altered parameters of cardiac function. CMRs in patients with rTOF-TAP were retrospectively reviewed; analysis included right and left ventricular (LV) volumes and ejection fractions (EF) and peak global LV circumferential strain (ε cc) from myocardial tagged images...

Background -The effect of angiotensin II receptor blockers (ARBs) on right ventricular (RV) function is still unknown. ARBs are beneficial in patients with acquired left ventricular (LV) dysfunction and recent findings suggested a favorable effect in symptomatic patients with systemic RV dysfunction. The current study aimed to determine the effect of losartan, an ARB, on subpulmonary RV dysfunction in adults after repair of tetralogy of Fallot (rTOF). Methods -REDEFINE is an investigator-initiated, multicenter, prospective, 1:1 randomized, double-blind, placebo-controlled study...
