Antegrade balloon valvuloplasty for critical aortic stenosis in a premature neonate weighing 1100 g.
Experiences with invasive cardiac catheterization in low birth weight infants are few. In our clinic, we performed balloon aortic valvuloplasty by antegrade approach in a neonate weighing 1100 g with critical aortic stenosis, patent ductus arteriosus and atrial septal defect. The right femoral vein was accessed with a 4 Fr sheath, and a catheter was placed into the left ventricle from the atria...
Besides the standart echcardiografic parameters for mitral stenosis assessment it is necessary to inquire hemodynamic characteristics as well. The following article describes and illustrates step-by-step invasive their significance in of patients who underwent percutaneous balloon valvuloplasty.
Aortic valve replacement in the setting of critical aortic valve stenosis with cardiogenic shock is associated with high mortality, yet surgery is the only definitive treatment. We present the case of a patient with critical aortic valve stenosis and cardiogenic shock who received a short period of percutaneous mechanical support and balloon aortic valvuloplasty that resulted in rapid clinical ...
The application of balloon aortic valvuloplasty to elderly patients with severe aortic stenosis and a low ventricular ejection fraction is undefined. Balloon aortic valvuloplasty was performed in a subset of 28 patients with low left ventricular ejection fraction (37 +/- 11%), severe aortic stenosis, and a mean age of 79 +/- 5 years. After valvuloplasty, significant increases were seen in aorti...
BACKGROUND Transcatheter aortic valve implantation is currently being evaluated in patients with severe aortic stenosis who are considered high-risk surgical candidates. This study aimed to detect incidences, causes, and correlates of mortality in patients ineligible to participate in transcatheter aortic valve implantation studies. METHODS AND RESULTS From April 2007 to July 2009, a cohort o...
Congenital valvular pulmonary stenosis accounts for 5-10% of all congenital heart disease. Balloon valvuloplasty is a safe and effective method in reduction moderate to severe stenosis. This retrospective study done Hawler surgical specialty cardiac center on pediatric patients who had valve (with echocardiographic peak gradient 2:50mmHg) treated by balloon valvuloplasty. A total 178 cases were...
A 4-month-old entire male Coton de Tulear dog was referred for balloon valvuloplasty treatment of severe valvular pulmonic stenosis. During the procedure, when attempting to pass guide wire into ventricle, developed cardiac arrest. After initial resuscitation with chest compressions, manual ventilation, adrenaline and intravenous fluids, focused ultrasound revealed pericardial effusion tamponad...
Transluminal balloon valvuloplasty was used to treat congenital pulmonary valve stenosis in 20 patients. Follow-up cardiac catheterization was performed in 11 patients at intervals of from 2 to 12 months after the procedure. Peak systolic pressure gradient across the pulmonic valve decreased from 68 +/- 27 to 23 +/- 5 mm Hg (p less than .001) after valvuloplasty. There were no complications. Fo...
Background: Measurements of mitral valve area (MVA) are essential to determine the severity of mitral stenosis (MS) and adopt the best management strategies. The aim of the present study was to compare MVA determined by two-dimensional (2D) planimetry to MVA measured by continuity equation (CE) in patients with moderate to severe MS. Methods: We evaluated 73 consecutive patients with the diagno...
OBJECTIVES We sought to study the potential role of balloon aortic valvuloplasty (BAV) in sizing the aortic annulus in patients before transcatheter heart valve (THV) implantation. BACKGROUND Despite clinicians' growing experience with THV procedures, the best method of annulus sizing remains unclear. METHODS Twenty-three patients with aortic stenosis (<1.0 cm(2)) who were undergoing surgic...
