Phenotyping exercise limitation of patients with Interstitial Fibrosing Lung Disease: the importance of exercise hemodynamics.

Pulmonology 2022 May 11. Epub 2022 May 11.

University Department of Respiratory Medicine, General Hospital of Thessaloniki "G. Papanikolaou", Aristotle University of Thessaloniki, Thessaloniki, Greece.

Introduction And Objective: Left-heart dysfunction and pulmonary vasculopathy are increasingly recognized as contributing factors of exercise capacity limitation in interstitial fibrosing lung disease (IFLD). Moreover, the clinical significance of exercise pulmonary hypertension (ePH) in pulmonary and cardiac diseases has been documented, representing a risk factor for decreased exercise capacity and survival, progression to resting pulmonary hypertension (PH) and overall clinical worsening. We conducted a prospective study aiming at: (a) assessing the prevalence of PH and ePH in a cohort of 40 functionally limited patients with IFLD, (b) determining the post-capillary (postC) or pre-capillary (preC) etiology of either PH or ePH in this cohort, and (c) examining the correlations between invasively and non-invasively measured exercise variables among hemodynamic groups.

Structural and Hemodynamic Changes of the Right Ventricle in PH-HFpEF.

Int J Mol Sci 2022 Apr 20;23(9). Epub 2022 Apr 20.

Cardiovascular Diseases Unit, Cardio-Thoracic and Vascular Department, Le Scotte Hospital, 53100 Siena, Italy.

One of the most important diagnostic challenges in clinical practice is the distinction between pulmonary hypertension (PH) due to primitive pulmonary arterial hypertension (PAH) and PH due to left heart diseases. Both conditions share some common characteristics and pathophysiological pathways, making the two processes similar in several aspects. Their diagnostic differentiation is based on hemodynamic data on right heart catheterization, cardiac structural modifications, and therapeutic response. Read More

Ventricular mass discriminates pulmonary arterial hypertension as redefined at the Sixth World Symposium on Pulmonary Hypertension.

Pulm Circ 2022 Jan 18;12(1):e12005. Epub 2022 Jan 18.

Department of Medicine, Division of Pulmonary and Critical Care Medicine Johns Hopkins University Baltimore Maryland USA.

Cardiac magnetic resonance (CMR) measures of right ventricular (RV) mass, volumes, and function have diagnostic and prognostic value in pulmonary arterial hypertension (PAH). We hypothesized that RV mass-based metrics would discriminate incident PAH as redefined by the lower mean pulmonary arterial pressure (mPAP) threshold of >20 mmHg at the Sixth World Symposium on Pulmonary Hypertension (6th WSPH). Eighty-nine subjects with suspected PAH underwent CMR imaging, including 64 subjects with systemic sclerosis (SSc). Read More

A Rare Presentation of Systolic Anterior Motion Occurring Eight Years After Mitral Valve Replacement.

Cureus 2022 Mar 13;14(3):e23114. Epub 2022 Mar 13.

Department of Internal Medicine, Vassar Brothers Medical Center, Poughkeepsie, USA.

Systolic anterior motion (SAM) is the dynamic displacement of mitral valve leaflets anteriorly toward the left ventricular outflow tract (LVOT) during systole. SAM-like physiology has been reported to occur shortly after mitral valve replacement (MVR) surgery; occurrence beyond two years after surgery is very rare. A 55-year-old woman who had bioprosthetic MVR eight years earlier for non-rheumatic mitral stenosis presented to the emergency room with progressive dyspnea and sudden-onset chest pressure.

Left Ventricle Biomechanics of Low-Flow, Low-Gradient Aortic Stenosis: A Patient-Specific Computational Model.

Front Physiol 2022 6;13:848011. Epub 2022 Apr 6.

Department of Surgery, University of California, San Francisco, San Francisco, CA, United States.

This study aimed to create an imaging-derived patient-specific computational model of low-flow, low-gradient (LFLG) aortic stenosis (AS) to obtain biomechanics data about the left ventricle. LFLG AS is now a commonly recognized sub-type of aortic stenosis.

Acute echocardiographic and hemodynamic response to his-bundle pacing in patients with first-degree atrioventricular block.

Ann Noninvasive Electrocardiol 2022 Apr 21:e12954. Epub 2022 Apr 21.

Division of Cardiology, Department of Medicine, Duke University, Durham, North Carolina, USA.

Background: Atrial pacing and right ventricular (RV) pacing are both associated with adverse outcomes among patients with first-degree atrioventricular block (1°AVB). His-bundle pacing (HBP) provides physiological activation of the ventricle and may be able to improve both atrioventricular (AV) and inter-ventricular synchrony in 1°AVB patients. This study evaluates the acute echocardiographic and hemodynamic effects of atrial, atrial-His-bundle sequential (AH), and atrial-ventricular (AV) sequential pacing in 1°AVB patients. Read More

A geometrical pitfall of Area-Length method; -Is left ventricle volume evaluation of repaired Tetralogy of Fallot by angiocardiography accurate?

Heart Vessels 2022 Apr 18. Epub 2022 Apr 18.

Department of Pediatrics, Hokkaido University Hospital, North 15 West 7, Kita-ku, Sapporo, 060-8638, Japan.

Biplane Area-Length (AL) method by left ventriculography (LVG) has been widely adopted as a standard method to estimate left ventricular volume. However, we have experienced difficulties in adopting the value by AL method for the children with Tetralogy of Fallot (TOF) due to the discrepancy among volumetric modalities. This study validated some limitations of AL method, considering the basic principles of its formulation. Read More
