Echocardiographic and angiographic evaluation of left ventricular function during percutaneous transluminal aortic valvuloplasty.

1992

Transesophageal echocardiography was used to study the effect of the balloon inflation on left ventricular function in 20 patients with critical aortic stenosis undergoing balloon valvuloplasty. Balloon inflation caused an increase of end-diastolic (15% to 34%) and end-systolic (57% to 72%) left ventricular volume. Left ventricular wall stress increased from 30 +/- 10 x 10(3) dyn/cm2 at diastole and 121 +/- 40 x 10(3) dyn/cm2 at systole to 44 +/- 11 x 10(3) dyn/cm2 and 191 +/- 55 x 10(3) dyn/cm2, respectively, when the balloon was inflated (P less than 0.05). Turbulent regurgitant jet across the mitral valve increased from 15 +/- 2% to 25 +/- 3% during balloon inflation (P less than 0.01). …

Assessment of left ventricular function during aortic balloon valvuloplasty by transesophageal echocardiography

1989

Several reports have documented the feasability and utility of balloon aortic valvuloplasty as a palliative treatment for high-surgical-risk patients with critical aortic valve stenosis (1–3).

Balloon aortic valvuloplasty, Impella insertion and complex coronary intervention: is this all feasible fully percutaneously via upper limb access?

2021

Complex high-risk indicated patients (CHIP) with a limited vascular access constitute a real challenge for percutaneous coronary interventions (PCI), particularly if they require mechanical circulatory support devices. A 73-year-old man with recent non-ST segment elevation myocardial infraction, depressed left ventricular function (ejection fraction, 40%), aortic stenosis (max/mean gradient, 50/32 mm Hg; aortic valve area and its index, 1.0 cm2 and 0.5 cm2/m2) and numerous comorbidities (including recently diagnosed lung cancer in the initial phase) was scheduled by the heart team for balloon aortic valvuloplasty (BAV) and Impella-supported complex PCI of the left main (LM) and the left ant…
