[Prognostic impact of heart block during transcatheter closure of ventricular septal defect].

Zhonghua Xin Xue Guan Bing Za Zhi 2009 Nov;37(11):990-3

Department of Cardiology, Southwest Hospital, Third Military Medical University, Chongqing 400038, China.

Objective: To investigate the prognostic impact of heart block during the transcatheter closure of ventricular septal defect (VSD).

Methods: Forty three patients developed complete left or right bundle branch block (CLBBB, CRBBB), incomplete left or right bundle branch block (ILBBB, IRBBB), and atrioventricular block (AVB) during and within 1 week post procedure were followuped at 1, 6, 12, 24, 36, 48 and 60 months post procedure. Electrocardiogram, dynamic electrocardiogram and transthoracic echocardiography were made.

Results: Bundle branch block and atrioventricular block were detected in 26 patients (CLBBB n = 4, CRBBB n = 5, ILBBB n = 2, IRBBB n = 10 and third-degree AVB n = 5) during the transcatheter closure of VSD, and in 17 patients (CLBBB n = 5, CRBBB n = 2, first-degree AVB n = 3, second-degree I-type AVB n = 1 and third-degree AVB n = 6) within 1 week post procedure. Heart block disappeared in 33 patients (76.7%) before discharge, in 37 patients (86.1%) at 1 month and in 41 patients (95.4%) at 6 months post procedure. CLBBB or CRBBB was seen in two cases at 24 months after closure. There was no heart failure and serious cardiac dilatation during follow up.

Conclusion: The heart block occurred during the periprocedure period of transcatheter closure of VSD was a benign phenomenon without prognostic importance.

Clinical efficiency and safety analysis of transcatheter closure of multiple atrial septal defects in adults.

Clin Cardiol 2009 Mar;32(3):130-4

Department of Cardiology, Southwest Hospital, Third Military Medical University, Chongqing, People's Republic of China.

Background: Transcatheter closure of atrial septal defects (ASDs) is currently a reliable alternative to surgery, even though challenging in patients with multiple ASDs.

Hypothesis: The aim of this study was to evaluate the clinical efficiency and safety of transcatheter closure in multiple ASDs.

Methods: Multiple ASDs were diagnosed by transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE). The occlusive condition and distance between 2 adjacent ASDs were measured by TTE examination. Then, the number and size of the occluder(s) was determined. TTE examinations were performed after transcatheter closure as follow-up.

Results: The transcatheter procedure was successful in 15 patients with multiple ASDs, using a single occluder in 9 patients and 2 occluders in the remaining 6 patients. Overall, 21 ASD occluders were implanted. During a follow-up period of 6 mo to 5 y, a slight residual shunt was found in 1 patient without any symptoms; a moderate residual shunt was identified at the inferior vena cava and the occluder was removed by surgery 1 mo after procedure. Other complications, including endocarditis, arrhythmia, thromboembolism, and atrioventricular valve damage were not recorded in any of the 15 patients during the follow-up period.

Conclusion: Transcatheter closure of multiple ASDs is safe and efficient. Two occluders are necessary for the distance of 2 ASDs more than 7 mm, and a single occluder is sufficient for those 7 mm or less.

Clinical efficiency and safety analysis of transcatheter interventional therapy for compound congenital cardiovascular abnormalities.

Clin Cardiol 2007 Oct;30(10):518-21

Department of Cardiology, Southwest Hospital, The Third Military Medical University, Chongqing, China.

Objective: To investigate the efficiency and safety of transcatheter interventional therapy for compound congenital cardiovascular abnormalities.

Methods: From Nov 2001 to Jun 2006, a total of 36 patients (17 male, 19 female), aged 17.20 +/- 10.52, with compound congenital cardiovascular abnormalities underwent transcatheter interventional procedure. These patients included 11 with perimembranous ventricular septal defect (PVSD) and patent ductus arteriosus (PDA), 8 patients with PVSD and atrial septal defect (ASD), 8 patients with ASD and PDA, 7 patients with ASD and pulmonary stenosis (PS), 1 patient with ASD and mitral stenosis(MS), 1 patient with coarctation of aorta (COA) and PDA. According to the principle of "easy first, hard second," balloon valvuloplasties of PS or MS were performed before the closure of PVSD, and of PDA and ASD. Electrocardiogram and transthoracic echocardiogram were examined at 4 days, 1, 2, 6 and 12 months, respectively, after each procedure.

Results: Transcatheter interventional therapy for compound congenital cardiovascular abnormalities was successful in all patients. Among these, 2 occluders were planted in each of 27 patients, 7 patients with ASD combined with PS and 1 patient with ASD combined with MS underwent successfully performed balloon valvuloplasty and ASD closure, 1 patient with COA combined with PDA underwent successfully performed balloon valvuloplasty and subsequent covered stent implantation. No patient encountered serious adverse events during the (30.5 +/- 14.6) months of follow-up.

Conclusions: Transcatheter interventional therapy for compound congenital cardiovascular abnormalities could obtain satisfactory results with technical feasibility.
