Study of Left Ventricular Diastolic Diameter-Peak Stress Relationship before and after Valve Replacement Operation for Patients with Chronic Aortic Regurgitation

, 2011
Background: Patients with chronic aortic regurgitation (AR) usually have dilated left ventricle due to volume overload. Some of them will reduce in size after elimination of regurgitation, but others not.

Transcarotid aortic valve-in-valve implantation for degenerated stentless aortic root conduits with severe regurgitation: a case series [PDF]

, 2015
OBJECTIVES Transcatheter aortic valve implantation (TAVI) is routinely performed via the transfemoral and the transapical route. Subclavian and direct aortic access are described alternatives for TAVI.

Postprandial Changes in Thoracic Aortic Flow Detected by 4D Flow MRI May Influence Study Results

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background While there is a growing body of data using 4D flow MRI to distinguish between normal and abnormal blood flow values in the thoracic aorta, the extent of physiological variation or lack thereof is potentially undervalued. Physiological processes such as postprandial changes to hemodynamics might influence data, normal values, follow‐

Autonomous Velocity Encoding (VENC) Selection Improves Precision of Quantitative Flow Measurement

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The optimal velocity encoding limit (VENC) in phase contrast MRI is subject‐specific because it depends on peak flow rate and the presence of flow jets. Currently, VENC is set manually with limited prior knowledge of the peak velocity. Setting the correct VENC might improve measurement precision or shorten scan times.

Congenital aortic Regurgitation: Natural history and management [PDF]

, 1992
Objectives and Background. Congenital aortic regurgitation is rare as an isolated lesion. We describe seven children with no physical features of the Marfan syndrome in the patients or their families and no cardiac lesions who had congenital valvular ...

Therapeutic‐dose verapamil‐induced cardiogenic shock in an older patient: a case report

Journal of Pharmacy Practice and Research, EarlyView.
Abstract Background Calcium channel blocker (CCB) toxicity most commonly follows deliberate overdose. However, severe toxicity at therapeutic doses may occur in susceptible individuals. Severe CCB toxicity often presents with clinical features of bradycardia, hypotension, hyperglycaemia, and lactic acidosis.

Aortitis as a Rare Cause of Aortic Aneurysm and Valve Regurgitation: Is Repair Precluded?

Case Reports in Cardiology, 2018
Aortitis is an infrequent cause of aortic root dilatation and aortic valve regurgitation. Valve-sparing procedures have been proposed, but there is not clear evidence of which is the treatment of choice.

Type II achalasia unmasked by EndoFLIP and high‐resolution manometry in a child with eosinophilic esophagitis

JPGN Reports, EarlyView.
ABSTRACT Eosinophilic esophagitis (EoE) is a chronic immune‐mediated disease characterized by esophageal dysfunction and eosinophilic inflammation. Persistent dysphagia despite histologic remission should prompt evaluation for alternative etiologies. A 10‐year‐old male with asthma and eczema presented with progressive solid food dysphagia, daily non ...
