Pentalogy of Fallot is a rare cyanotic congenital heart disease characterized by biventricular origin of the aorta above a large ventricular septal defect, obstruction of the pulmonary outflow, right ventricular hypertrophy (tetralogy of Fallot), and an atrial septal defect. Mortality due to syncope, arrhythmia or congestive heart failure is about 75% by the age of 10 years and 97% by the age of 40. We report a 69-year old female with uncorrected pentalogy of Fallot who suffered from recurrent syncope during classic cyanotic spells. Treatment with bisoprolol is recommended in symptomatic children and also improved symptoms in our patient. We conclude that single patients with pentalogy of Fallot reach the seventh decade and that cyanotic congenital heart disease is a rare cause of syncope in the elderly.
Although heart failure is predominantly caused by cardiovascular disorders, several classes of drugs may induce heart failure in patients with pre-existing normal left ventricular function or may precipitate the occurrence of heart failure in patients with left ventricular impairment. These drugs are predominantly those belonging to the categories of cytostatics, anti-arrhythmics, beta-blockers, nonsteroidal anti-inflammatory drugs, calcium channel blockers and anaesthetics. Drug-induced heart failure should be regarded as a potentially preventable cause of heart failure, although sometimes therapeutic alternatives are scarce (e.g. anthracycline-induced cardiomyopathy). Awareness of the possibility of adverse effects on cardiac performance by several classes of drugs, particularly in patients with pre-existing ventricular impairment, may contribute to prevention or timely diagnosis and treatment of drug-induced heart failure.
