bifid cardiac apex is a rare anomaly of human hearts. we report of the case of a 34-year-old man with a previous history of ventricular septal defect (vsd) and subvalvular pulmonary stenosis. he had undergone pulmonary commissurotomy and vsd closure 22 years before he was referred to our center for evaluation of progressive dyspnea. transthoracic echocardiography revealed atrial septal defect (...

marfan’s syndrome (mfs) is a genetic disorder associated with autosomal dominant inheritance. in mfs, the most prevalent cause of death is cardiovascular involvement. here we introduce a family with a severe penetration of mfs. eleven members of this family have mfs (father, two daughters, three sons, and five grandchildren). the most common cardiac involvement in our patients was mitral valve ...

Introduction: Heart valve disease in pediatricsis an increasing global concern, especially in developing countries. This study aims to determine the clinical outcomes of pulmonary valve replacement (PVR) surgery in pediatrics. Methods: The authors retrospectively identified all pediatrics undergoing PVR surgery at Imam Reza hospital (Mashhad, Iran) between 2000 and 2020. Their medical records...

the optimal treatment method for right ventricular failure after valve surgery complicated by a low cardiac output has not been determined, although several case reports have been published on patients with ventricular failure and arrhythmia who were bridged to cardiac transplantation using biventricular or left ventricular assist devices. this case series illustrates successful circulatory sup...

Article type: Case report Recently, there have been more reports of cardiac valve infections due to the increasing number of intravenous (IV) drug abusers and chronic renal failure patients. Among cardiac valves, tricuspid valve is most commonly affected in the course of endocarditis. Appropriate management of these patients is a challenging and controversial issue in the field of cardiac surge...

Interpretation of the meaning of a mean diastolic atrioventricular gradient or a mean systolic ventricular-great vessel gradient requires simultaneous determination of the level of the gradient, the heart rate, and the cardiac output. The feasibility of steady-state Fick principle cardiac output determination during combined right and left heart catheterization is investigated. LEFT heart cathe...

BACKGROUND Since 2000, transcatheter pulmonary valve replacement has steadily advanced. However, the available prosthetic valves are restricted to bioprosthesis which have defects like poor durability. Polymeric heart valve is thought as a promising alternative to bioprosthesis. In this study, we introduced a novel polymeric transcatheter pulmonary valve and evaluated its feasibility and safety...

BACKGROUND To report early and late outcomes of patients with the primary cardiac valve tumor undergoing surgical treatment over a 30-year period in our cardiovascular center. METHODS From January 1980 to December 2014, a total of 211 patients with primary cardiac tumors accepted surgical treatments, of which only 8 (3.8 %) were primary cardiac valve tumor patients in our surgical center of c...

Communications to the Editor by both cardiac Doppler examination and catheterization might have been misleading because of the low cardiac output. The correct diagnosis of critical aortic valve stenosis was possible only on the basis ofestimation ofthe valve area by Doppler study, confirmed by cardiac catheterization and later at necropsy. Our case underlines the fact that the only way to estab...

We tested the hypotheses that Doppler echocardiography has a higher accuracy than clinical evaluation in the detection of significant aortic and mitral valvular heart disease and that Doppler echocardiography is highly accurate as compared with cardiac catheterization for the assessment of valvular disease severity. Thus, cardiac catheterization for the assessment of valve lesion severity may b...
