Between 1993-1996 seventy-three consecutive patients (33 M, 40 F, mean age 35.4) with newly diagnosed achalasia underwent one or more pneumatic dilatations with the Rigiflex balloon using a protocol of graded dilatation with a fixed inflation pressure of 10 psi and constant duration of 30 seconds for all patients without using fluoroscopy. Using Vantrappen's classification for assessment of...

Introduction: Post-dilatation is associated with a simultaneous expansion of the stents that enhances the angioplasty outcomes. However, increased risk of mortality and morbidity has been reported in patients with acute myocardial infarction (AMI) which has provoked considerable controversies concerning its efficiency. Materials and Methods: During a two-...

Acquired stenosis of the trachea or bronchus in newborn infants is a possible complication of perinatal intubation and mechanical ventilation. Although the exact pathophysiology is unknown, stenosis formation seems to be initiated by pressure necrosis. Prematurity is thought to be an important risk factor for acquired airway stenosis. Management of stenotic lesions may be conservative, surgical...

The outcome of unrelieved severe symptomatic aortic stenosis in pregnancy is poor. Though the valve lesion can be corrected surgically before delivery at a low risk to the mother, cardiopulmonary bypass during pregnancy carries a high risk to the fetus. Two patients in the second trimester of pregnancy were successfully managed with balloon dilatation of the aortic valve. Both delivered healthy...

Background: Endoscopic treatment of ureteral strictures provides a minimally invasive approach with shorter hospital stay and less postoperative pain. There are different therapeutic options, the dilatation balloon endoureterotomy holmium yttrium-aluminum-garnet (Ho:YAG) laser most used. To assess histological changes after in stricture comparing Ho:YAG versus endoureterotomy.

Balloon dilatation was successfully performed in two patients with complete obstruction of the superior vena cava baffle junction after a Mustard operation for transposition of the great arteries. Evidence for complete relief of obstruction in the first patient, aged 4 years, was obtained by angiography, which showed improved calibre at the site of obstruction and improved haemodynamic pressure...

Objective: To evaluate the impact of post dilatation performed with Non- Compliant Balloon on Angiographical outcome (that is TIMI flow grade) in patients who underwent primary percutaneous coronary intervention.
 Study Design: Retrospective cross-sectional study.
 Place and Duration Study: At Tertiary Cardiac Care Center, Rawalpindi Pakistan from Nov 2020 to Apr 2021.
