Precordial exercise electrocardiographic mapping and exercise 201-thallium scintigraphy were simultaneously used on sixteen patients before, shortly after and three months after percutaneous transluminal coronary angioplasty (PTCA) to evaluate the immediate and late results of the intervention. In spite of the limited number of observations, positive exercise precordial mapping and or a reversible 201-thallium perfusion defect after PTCA seem to be indicative of failure of balloon dilatation or of development of restenosis in a given coronary artery. "Reverse minimum", that is the minimum in the resting precordial map which disappears on exercise, may be a sign of segmental coronary artery occlusion and well functioning collateral supply.

The management of locally advanced esophageal cancer typically involves esophagectomy; however, postoperative complications, particularly anastomotic stricture, remain prevalent. Anastomotic stricture can severely compromise patients' quality of life by leading to difficulties in food intake. Although endoscopic balloon dilation has become a standard treatment for gastrointestinal strictures, its efficacy is often limited due to the risk of perforation and the potential for recurrent stricture, necessitating multiple interventions.

Background: Coarctation of the aorta (CoA) is a narrowing of the aorta that affects 5-8% of congenital heart defects. Treatment options include surgical repair or transcatheter management with endovascular stenting or balloon dilatation. Late complications after operative repair include systemic hypertension, aortic valve abnormalities, aortic aneurysm, and recoarctation.

Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.
Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.
Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.
Cervical balloon catheter versus Dilapan-S for outpatient cervical ripening: A randomized controlled trial.
Am J Obstet Gynecol MFM

Division of Maternal Fetal Medicine, Brigham and Women's Hospital.
Background: As induction of labor increases in the United States, safe, effective outpatient cervical ripening has been explored as a method to decrease the inpatient time burden. The most effective method of outpatient mechanical cervical ripening remains unclear.
Objective: To evaluate if Dilapan-S is non-inferior to cervical balloon for outpatient cervical ripening (CR) based on change in Bishop score.
Background: Predicting successful outcomes of gastric peroral endoscopic myotomy (G-POEM) is essential for identifying patients who are most likely to benefit from the procedure. This study aimed to evaluate the utility of the balloon dilation test (BDT) in optimizing patient selection for G-POEM.
Methods: A retrospective study was conducted from February 2021 to December 2023, including patients with refractory gastroparesis unresponsive to conventional medical treatments.
