BACKGROUND Transcatheter balloon aortic valvuloplasty for critical aortic stenosis in neonates is routinely performed without recognized complication. Aortic wall injury has rarely been observed after balloon aortic valvuloplasty, although the incidence of this complication is unstudied. We reviewed single-center data to determine the incidence of aortic injury during balloon aortic valvuloplas...

Balloon valvuloplasty techniques and equipment have continued to evolve over the last two decades. With this expanded experience, there has been refinement in patient selection and a clearer understanding of the benefits, limitations, and long-term results of balloon valvuloplasty. In this chapter the mechanisms, indications, techniques and clinical results of balloon valvuloplasty of the mitra...

Following the description by Lababidi in 1983 of balloon aortic valvuloplasty, it has been adopted by several groups of workers for relief of aortic valve stenosis. The indications for the procedure are peak-to-peak systolic pressure gradients in excess of 50 mmHg with symptoms or ECG changes or a gradient greater than 70 mmHg irrespective of the symptoms or ECG changes. One or more balloon dil...

Balloon aortic valvuloplasty was introduced over two decades ago as an alternative to aortic valve replacement in elderly patients deemed unsuitable for surgery. Due to high early restenosis rates and no effect on longterm mortality, the procedure’s development stalled. However, with recent technological advances, in particular the advent of the transcatheter aortic valve implantation, there ha...

Calcific aortic stenosis is the most common valvular disease in the western world, with the prevalence increasing with age. Medical management of critical aortic stenosis is associated with high mortality and cost. While surgical valve replacement is ideal, high early morbidity and mortality limit its usefulness among patients with comorbid illness or advanced age. Balloon aortic valvuloplasty ...

OBJECTIVES To investigate the effects of transvalvar flow rate on aortic valve resistance and valve area after percutaneous transvenous balloon dilatation of the mitral valve in a homogeneous group of patients with rheumatic heart disease. DESIGN Retrospective analysis of 12 patients with combined aortic and mitral stenosis who had undergone balloon dilatation of the mitral valve over a perio...

Prenatal intervention of severe fetal aortic valve stenosis by ultrasound-guided percutaneous balloon valvuloplasty has been performed to prevent the progression to hypoplastic left heart syndrome, and achieve biventricular circulation in neonates. Here we report a case of fetal aortic valvuloplasty prenatally diagnosed with aortic stenosis at 24 weeks of gestation and showed worsening features...

Balloon aortic valvuloplasty is recommended in patients not suitable for transcatheter aortic valve implantation/aortic valve replacement (TAVI/AVR) or when such interventions are temporarily contraindicated. The number of performed balloon aortic valvuloplasty (BAV) procedures has been increasing in recent years. Valvuloplasty enables the selection of individuals with severe left ventricular d...

Percutaneous aortic valvuloplasty is reportedly a useful tool for the management of critical and severe aortic stenosis with cardiogenic shock. However, early percutaneous coronary intervention for cardiogenic shock is beneficial for elderly patients with acute myocardial infarction. We describe a patient with critical aortic stenosis who presented with severe coronary stenosis of the left main...

Patients with aortic stenosis are susceptible to myocardial ischemia during hemodynamic stress, which may be caused by two mechanisms. First, vascular abnormalities inherent in myocardial hypertrophy may impair coronary vasodilation, limiting the ability to increase coronary blood flow to meet increased metabolic demands. Second, aortic stenosis itself may cause an imbalance between oxygen supp...
