The normal ranges of cardiovascular parameters measured using the ultrasonic cardiac output monitor [PDF]

, 2017
The ultrasonic cardiac output monitor (USCOM) is a noninvasive transcutaneous continuous wave Doppler method for assessing hemodynamics. There are no published reference ranges for normal values in adults (aged 18– 60 years) for this device.

Atrioventricular canal defect and genetic syndromes: the unifying role of sonic hedgehog [PDF]

, 2019
The atrioventricular canal defect (AVCD) is a congenital heart defect (CHD) frequently associated with extracardiac anomalies (75%). Previous observations from a personal series of patients with AVCD and "polydactyly syndromes" showed that the distinct ...

Response to pulmonary arterial hypertension drug therapies in patients with pulmonary arterial hypertension and cardiovascular risk factors. [PDF]

, 2014
The age at diagnosis of pulmonary arterial hypertension (PAH) and the prevalence of cardiovascular (CV) risk factors are increasing. We sought to determine whether the response to drug therapy was influenced by CV risk factors in PAH patients. We studied

Immediate, Short, Intermediate and Long-Term Results of Balloon Valvuloplasty in Congenital Pulmonary Valve Stenosis

Acta Medica Iranica, 2013
Transluminal balloon valvuloplasty is an alternative to surgical valvotomy for congenital pulmonary valve stenosis. The aim of this study was to evaluate the long term results (to 13.5 years) of balloon pulmonary valvuloplasty.

Amyloid β Instigates Cardiac Neurotrophic Signaling Impairment, Driving Alzheimer's Associated Heart Disease

Advanced Science, EarlyView.
This research identified cardiac amyloid pathology, neurotrophic factor depletion, and reduced myocardial nerve function in a transgenic model of cerebral amyloidosis (Tg2576), Aβ‐challenged cardiomyocytes, and in human AD heart tissue. These findings carry significant diagnostic and therapeutic implications, emphasizing the role of neuro‐signaling ...

Intimal spindle cell sarcoma masquerading as adult-onset symptomatic pulmonic stenosis: a case report and review of the literature

Journal of Cardiothoracic Surgery, 2017
Background Pulmonary artery intimal spindle cell sarcomas are rare and carry with them a poor prognosis and high rate of recurrence. In extremely rare cases, this tumor can infiltrate the pulmonic valve and manifest as adult-onset pulmonic stenosis. Case
