Unsuccessful pericardiocentesis for cardiac tamponade during angiocardiography with nonionic contrast material.

Cardiac tamponade secondary to ventricular wall perforation is one of the possible complications of right-sided as well as left-sided cardiac catheterization. Ventriculography was performed on a patient with obstructive cardiomyopathy using a nonionic contrast medium. During the procedure, the right ventricle was accidentally perforated and the patient developed cardiac tamponade. Pericardiocentesis was unsuccessful and surgical drainage was needed after the patient developed progressive hemodynamic deterioration. At surgery, pericardial thrombus was found. We consider the reason for failure of pericardiocentesis was rapid coagulation of the extravasated blood in connection with nonionic contrast material.

[Ambulatory heart catheterization. Initial experience].

Development of cardiovascular surgical techniques and more recently, balloon angioplasty, has resulted in a dramatic increase in the number of cardiac catheterizations performed. Previously, the usual policy was to admit the patient to the hospital for several days. Various series of patients submitted to ambulatory cardiac catheterizations have revealed that this procedure con be performed safely, with a potential reduction in hospital and patients costs, better utilization of medical beds and good image quality. In this study we present our initial experience in this kind of outpatient procedure.

[Technological improvements in interventional cardiology].

In the last few years, the evolution of coronary interventionism has been very important. The primary success rates in the early 1990s were 86-88% with a re-stenosis rate of 30%-40%. Current primary success rates have risen to over 95% with a re-stenosis rate of under 10% even for many types of lesions classically considered complex. Currently the main limitations in interventional cardiology remain coronary segments that cannot be accessed due to chronic total occlusion, or severe proximal tortuosity or calcification. Rapid improvements have led to broader clinical indications for percutaneous revascularization procedures. We describe the latest improvements in techniques.

[Effectiveness of atenolol in moderate arterial hypertension. Evaluation by stress test].

A study on the effect of atenolol on exercise blood pressure is presented. Twenty-eight patients with blood pressure over 95 mmHg have been studied by maximal or symptom-limited stress testing. The stress testing was repeated with the same protocol after four weeks of treatment with 100 mg of atenolol daily. Systolic blood pressure after treatment fell by 14% at rest, by 9.5% at submaximal effort and by 11% at maximal effort, while diastolic blood pressure by 15%, 11% and 12% respectively (p less than 0.001). This reduction was parallel to that on heart rate. After treatment, diastolic blood pressure fell to normal ranges in 64% of patients at rest and in 56% of them at maximal effort. Exercise tolerance was slightly better after treatment than before it, mean duration of effort raising from 12.6 to 13.03 minutes. Exercise-induced arrhythmias were frequent (46%) and severe in hypertensive patients, two of them having ventricular tachycardia. This rate was dramatically reduced (up to 7%) with atenolol, as well as its severity.
