This study evaluates the clinical outcome and incidence of left atrial (LA) macro re-entrant tachycardia (AT) in patients whom persistent fibrillation (AF) terminated during catheter ablation without need roof mitral lines. Persistent AF was by 154 180 consecutive patients. history 60 months including 11 continuous AF. Patients were divided into two groups: those who had not required both LA linear lesions to terminate (group A, 85 patients), B, 69 patients). There no difference...

Dear Sir, Brain tumors are diagnosed in 321,000 individuals annually, with over two-thirds succumbing to the disease. Early diagnosis is critical for better prognosis but challenging due nonspecific symptoms, including psychiatric manifestations that often precede neurological symptoms.[1] Understanding link between brain and symptoms essential comprehensive care. Psychiatric can result from various tumors, impacting mood, cognition, behavior.[2] We present a case of patient psychotic no...
