Objective To determine the diagnostic and therapeutic approach of cute cardiac perforation and tamponade complicating percutaneous balloon mitral valvuloplasty. Methods and Results Percutaneous balloon mitral valvuloplasty was performed in 772 patients with rheumatic mitral stenosis from May 1992 to Dec. 2001, 9 were diagnosed cardiac perforation, 2 which developed pericardial tamponade which was successfully controlled by contrast and X ray guided pericardiocentesis using a subxiphoid approach. Conclusions Only a minority of cardiac perforation resulted from PBMV developed pericardial tamponade. The latter could be controlled safely and effectively by contrast and X ray guided pericardiocentesis using a subxiphoid approach.The diagnosis of pericardial tamponade during or after PBMV relies on a strong clinical suspicion, and contrast and X ray guided pericardiocentesis should be carried out without echocardiography for patients in unstable state.

European Society of Hypertension/European Society of Cardiology jointly published new guidelines on diagnosis and treatment of hypertension in 2007.It reflected the the latest developments on comprehensive assessment,treatment modalities and strategies,as well as therapeutic approach for special populations.In addition,the new guidelines updated evaluation.It also stressed the importance of an early,faster and more stringent treatment and aggressive combination therapy.More impartantly,it requested prevention and treatment earlier.It is of great importance for the guidelines to guide the current diagnosis and treatment of hypertension.

Atrial fibrillation (AF) is the most common arrhythmia,but its pathogenesis is still unclear.With the development of sleep medicine,obstructive sleep apnea (OSA) is found to associate with the occurrence of AF and recurrence after catheter ablation.This article reviews the pathophysiology of OSA,and relationship between OSA and the occurrence of AF,and its mechanism.It indicates that clinicians should pay close attention to the existence of OSA during diagnosis and treatment of AF.

Objective To evaluate the outcome of AF ablation in patients with paroxysmal atrial fibrillation (AF) related tachycardia-bradycardia syndrome. Methods Fifty consecutive patients with paroxysmal AF and prolonged symptomatic sinus pauses on termination of AF referred to our hospital for ablation were evaluated (ABL group). In another 61 patients, paroxysmal AF was treated with anti-arrhythmic drug and a pacemaker was implanted due to AF related tachycardia-bradycardia syndrome. These patients were used as control (PM group). Results A total of 50 patients in the ABL group fulfilled Class I indication for pacemaker implantation at baseline but they actually underwent AF ablation. Re-evaluation at the end of follow-up showed that 47 (94%) patients no longer needed a pacemaker (Class III indication) because of free from AF with no recurrences of pre-syncopal or syncopal events or documented sinus pauses after the last procedure. More patients in the PM group were on AADs (PM 42.6%, ABL 6.0%, P < 0.001) while sinus rhythm maintenance at the end of follow-up was remarkably higher in the ABL group (82.0%vs. 21.3%in PM group, P < 0.001). The total rates of cardiac related re-hospitalization was not significantly different between the two groups, but hospitalizations caused by tachyarrhythmia was significantly higher in the PM group (PM group 14.8%, ABL group 2.0%, P=0.020).The embolic events, heart failure and death rate were not significantly different between the two groups. Conclusions In patients with paroxysmal AF related tachycardia-bradycardia syndrome, AF ablation seems to be superior to a strategy of pacing plus AAD. Pacemaker implantation can be waived in the majority of patients after a successful ablation.

By using the OEC 9600 mobile digital imaging system, 14 coronary stents were successfully implanted in all 13 cases of coronary heart disease. After the procedure,immediate satisfactory angiographic results were obtained without residual stenosis, and chest pain was relieved or disappeared in all cases. No major complications occurred except for groin hematoma in one case,these results suggest that intracoro-nary stenting is a safe and effective management for coronary heart disease.

Objective To explore the feasibility and safety of primary coronary stenting in the patients with coronary heart disease Methods From march 1997 to august 1999, 80 cases with 90 of lesions were selected for primary coronary stenting without the predilation procedure Their efficacy and success rate were analysed Results We smoothly pushed 85 stents into the lesion in the 80 patients, the success rate of primary coronary stenting was 94% with shorter duration of the procedure and lower cost In 3 lesions the stent did not cross the lesion and was successfully retrieved in the guiding catheter, in 1 cases the stent was lost in the systemic circulation with no further complications Conclusions Primary coronary stenting without predilation was safe and feasible in selected patients

Objective To investigate the safety and efficacy of circumferential pulmonary vein linear ablation guided by 3-D mapping system in patients with atrial fibrillation.Methods From April 2003 to March 2006,410 consecutive patients with atrial fibrillation underwent circumferential pulmonary vein linear ablation guided by 3-D mapping system(CARTO system or EnSite NavX TM system).Success was defined as symptomatic atrial tachyarrhythmia free after 3 months washout period.Results 96%of the 410 patients attained the ablation endpoint.After a mean of (12.4?6.8)months' follow-up,clinical success achieved in 77.3% of the patients with paroxysmal atrial fibrillation and 69.4% of the patients with persistent/permanent atrial fibrillation after first-time ablation procedure.The successs rate of the persistent/permanent atrial fibrillation was significantly lower than that of paroxysmal atrial fibrillation.Forty-one of the 103 patients with recurrent atrial fibrillation underwent ablation again.Thirty-one of the 41 patients(75.6%)were atrial tachyarrhythmia free during the follow-up.Severe complications included 4 cases of pericardial tamponade(0.97%)and 3 cases of stroke(0.73%).Pericardial tamponades were relieved by pericardiocentesis.The patients with stroke recovered well without any lingering effects.There was no death case.Conclusion Circumferential pulmonary vein linear ablation guided by 3-D mapping system is an effective therapy for atrial fibrillation patients with an acceptable safety.

Objective To compare the in-hospital and follow-up clinical results of percutaneous coronary intervention(PCI)and coronary artery bypass grafting(CABG)in patients with coronary artery disease and diabetes mellitus.Methods The DESIRE(drug-eluting stent impact on revascularization)is a single-center registry comparing coronary revascularization in our institution before and after the introduction of drug-eluting stents.Between July 2001 and June 2002,July 2003 and June 2004,1040 patients were referred for revascularization(PCI or CABG)during hospitalization.Clinical,angiographic,revascularization data clinical condition in hospital and the follow-up results were collected for retrospective analysis.In the present study,patients with diabetes were selected and divided into PCI and CABG groups.The primary endpoint is in-hospital and follow-up major adverse cardiovascular and cerebral events(MACCE).Results Compared with the CABG group,the PCI group had lower in-hospital MACCE rates(P0.05),but the PCI group had higher rates of repeat revascularization than that of the CABG group(P0.05).Conclusion Although PCI has lower in-hospital MACCE rates in diabetic patients,the follow-up MACCE rates of PCI and CABG are comparable,and PCI has even higher rates of repeat revascularization than CABG.With the increasing use of drug eluting stents,PCI might have better performance.

Objective To determine the impact of body mass index(BMI)on clinical outcomes in patients underwent coronary revascularization.Methods The DESIRE-plus(Drug-Eluting Stent Impact on Revascularization-plus)was a single-center registry study of coronary revascularization in our institution between 1 July 2004 and 30 September 2005.We analyzed patients with complete data of BMI from the DESIRE-plus trial,grouped by BMI(low BMI group:BMI
