Systemic sclerosis (SS) is a connective tissue disease and cardiac involvement is common. Primary cardiac involvement such as conduction system disturbances and arrhythmias can also occur. However, reports of sustained ventricular tachycardia (VT) are rare. We report a case of catheter ablation of sustained ventricular tachycardia in a patient with systemic sclerosis using a conventional mapping system. A 64-yr-old woman with a 10-yr history of SS was referred for management of her ventricular tachycardia. There was no structural abnormality in cardiac chambers. However, electrophysiologic study revealed electrical substrate of ventricular tachycardia which could be ablated with pacemapping and substrate mapping. This case demonstrated successful conventional mapping and catheter ablation in a hemodynamically unstable patient with SS.

Systemic sclerosis is a connective tissue disease characterized by alterations in microvascular structure and function. In these patients, numerous studies have demonstrated a relationship between capillary morphology and peripheral blood perfusion. Nailfold videocapillaroscopy reveals the peripheral microvascular morphology and thus allows classification and scoring of capillary abnormalities with respect to different microangiopathy patterns (early, active, and late). Laser Doppler flowmetry and laser speckle contrast analysis can be used to estimate cutaneous blood flow through microvessels and to assess and quantify blood perfusion at peripheral sites. These two methods are also used to identify changes in digital blood perfusion after the infusion of vasodilators.

OBJECTIVETo investigate the clinical efficacy of Shenzhe Zhuyun mixture (SZM) in treating esophageal lesion in patients with systemic sclerosis.

METHODSSixty-four patients conforming to the inclusion criteria were randomly divided into 2 groups, the treated group and the control group treated respectively by SZM and cisapride, with the blank preparation imitating the contrast one, the treatment course to both groups was 2 months. The clinical efficacy, the changes in symptom scores of esophageal lesion, the orthostatic and clinostatic time of barium passing through esophagus, the clinostatic esophageal emptying index of barium, and the widest transverse diameter of ectatic esophageal segment, as well as the influence of treatment on patients' quality of life were observed.

RESULTSThe total effective rate in the treated group was superior to that in the control group (96.9% vs 56.2%, P < 0.01). Symptom of esophageal lesion was significantly improved after treatment in both groups (P<0.01), and the improvement in the treated group was better than that in the control group (P <0.01). The time of Barium passing through esophagus, both orthostatic and clinostatic, and the esophageal emptying index of barium were improved in the treated group (P < 0.01), but the change of the widest transverse diameter of ectatic esophagus was insignificantly improved. While in the control group, excepting the clinostatic time of barium passing through was improved (P<0.01), the other indexes showed no obvious change. Patients' quality of life was significantly improved in the treated group, but improvement didn't revealed in the control group.

CONCLUSIONSZM can reinforce esophageal dynamic function in patients with systemic sclerosis, it can be an effective TCM prescription in treating esophageal lesion for them.
