Eight elderly patients (mean (SD) age 72-6 (8&5) years) with severe calcified stenosis of the aortic valve were considered for transluminal balloon dilatation in the Thoraxcenter between March and November 1986. In one patient the procedure could not be performed because of technical difficulties. Balloons of increasing diameter (13-25 mm) were successively passed retrogradely from the femoral ...

A newly available balloon dilator for the treatment of achalasia and its advantages over existing instruments are discussed. Our experience with its use in seven patients is described.

While investigating the outcomes of balloon dilatation procedures in patients with congenital obstructive lesions heart, several parallel observations were made. The purpose this review is to present these observations/phenomena/innovations related pulmonary stenosis (PS), aortic (AS), and coarctation (AC). In subjects who had valvuloplasty (BPV), development infundibular obstruction, electroca...

To study the determinants of smooth muscle injury during balloon angioplasty, we conducted a series of experiments to examine the effects of degree of arterial stretching, duration of balloon inflation, and arterial precontraction on smooth muscle injury after balloon angioplasty in isolated, perfused whole-vessel segments of rabbit aortas and dog carotid arteries. Freshly dissected rabbit thor...

OBJECTIVES To assess the effectiveness of atrial septostomy by percutaneous balloon dilatation in patients with congenital heart defects or primary pulmonary hypertension. PATIENTS AND DESIGN Twenty three patients (15 boys, eight girls; aged 10 days to 10 years; 17 with congenital heart defects and six with primary pulmonary hypertension), all haemodynamically unstable under optimal medical t...

Percutaneous coronary intervention (PCI) using both balloon angioplasty and coronary stents has markedly reduced adverse cardiac events in patients with ischemic heart disease. Drug-eluting stents (DES) could further decrease the incidence of target vessel revascularization (TVR) to 5%–10% compared to bare-metal stents (BMS) or balloon angioplasty alone.1) Despite its clinical benefits, stent f...

A 75-year-old male patient with a history of hypertension and hypercholesterolemia was referred to our centre with ACS. During previous interventions, a cutting balloon (CB) dilatation, noncompliant (NC) and drug-eluting balloon dilatations, and an NC balloon dilatation with drug-eluting stent implantation (DES, Xcience 4x18 mm, Abbot Vascular, USA) of the mid-right coronary artery (RCA) had be...
