Left atrial myxoma development after radiofrequency ablation of an atrial flutter substrate.

A 51-year-old man developed symptoms (palpitations) related to a large left atrial mass attached to interatrial septum discovered by trans-thoracic heart ultrasonography. Six months earlier this patient had undergone radiofrequency ablation (RFA) of an atrial flutter substrate. The left atrial mass was removed surgically using cardiopulmonary bypass with disappearance of symptoms.

Short-term results of a 5-week comprehensive cardiac rehabilitation program after first-time myocardial infarction.

Background: A prospective single-center interventional cohort study was conducted to evaluate the effects of a 5-week comprehensive cardiac rehabilitation program on terms exercise capacity, quality of life, echocardiographic findings and autonomic modulation after first-time myocardial infarction.

Methods: We studied 37 consecutive post-myocardial infartion patients (mean age 66 years). All patients began a 5-week cardiac rehabilitation supervised training.

Atrioventricular node reentrant tachycardia (AVNRT) after mitral valvuloplasty during cardiac rehabilitation.

We descrive a patient who presents palpitations during cardiac rehabilitation after mitral valvuloplasty. ECG showed regular narrow QRS tachycardia compatible with Atrioventricular Node Reentrant Tachycardia. After slow pathway radiofrequency catheter ablation, the patient completed the rehabilitation program remained tachycardia and palpitations-free.
