Hybrid Transcatheter Pulmonary Valve Replacement With SAPIEN S3 Following Right Ventricular Outflow Tract Reduction Using Tricuspid Annuloplasty Rings

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We describe a novel variation of hybrid TPVR using a tricuspid annuloplasty ring which can be considered for patients with very large RVOT, short pulmonary artery, and limited vascular access and to avoid the risk of cardiopulmonary bypass. The utilization of Carpentier‐Edwards Physio Tricuspid annuloplasty ring can reduce the size of the RVOT

Inflammatory Characteristics of Stenotic Aortic Valves: A Comparison between Rheumatic and Nonrheumatic Aortic Stenosis

open access: yesCardiology Research and Practice, 2013
Background. Although our comprehension of nonrheumatic aortic stenosis (NRAS) has increased substantially during the last decade, less is known about the histopathology of rheumatic aortic stenosis (RAS).

Diagnostic Accuracy of Angiography‐Derived Murray Law‐Based Quantitative Flow Ratio (μQFR) Versus Pressure‐Derived Fractional Flow Reserve (FFR) in Moderate to Severe Calcified Coronary Lesions—The DIAMOND Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based Quantitative Flow Ratio (μQFR) is an innovative AI‐driven method for evaluating coronary lesions using contrast flow velocity estimates. Unlike traditional approaches, μQFR does not require pressure wires or hyperemia induction.

A Rare Case of Nitroglycerin Resistant Coronary Arterial Vasospasm During Coronary Artery Bypass Surgery

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary artery vasospasm following coronary artery bypass grafting (CABG) is a rare but potentially life‐threatening complication that can lead to myocardial ischemia, arrhythmias, and cardiogenic shock. Nitroglycerin‐resistant vasospasm, particularly involving the left main coronary artery (LMCA), poses significant diagnostic and ...

Assimilated LVEF: A Bayesian technique combining human intuition with machine measurement for sharper estimates of left ventricular ejection fraction and stronger association with outcomes [PDF]

open access: yesarXiv, 2018
The cardiologist's main tool for measuring systolic heart failure is left ventricular ejection fraction (LVEF). Trained cardiologist's report both a visual and machine-guided measurement of LVEF, but only use this machine-guided measurement in analysis.

Pressure‐Wire Guided Hybrid Branch Pulmonary Artery Band Placement for Palliation of Single Ventricle and Critical Congenital Cardiac Lesions

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Historically, bilateral pulmonary artery band (PAB) placement was guided by pulmonary blood flow surrogates including systemic blood pressure (BP) and arterial saturation. These metrics alone may result in suboptimal bPAB placement.

Comparative study of pressure (ankle-brachial pressure index) and flow (strain gauge plethysmography and reactive hyperaemia) measurements in diagnosis of peripheral arterial disease in patients with severe aortic stenosis.

open access: yesPLoS ONE, 2019
BackgroundThe measurement of the ankle-brachial pressure index is a straightforward method for the detection of peripheral disease in the lower limbs. Only a few old studies with small numbers of patients have been conducted comparing the gold standard ...
