Cardiac tamponade secondary to leptospirosis. A rare association: A case report.

Herein is described the case of a 39-year-old female agronomist who was admitted to hospital after a syncopal episode. She had had fever, abdominal pain, nausea, and vomiting for the previous month. The patient showed signs of hypoperfusion, so a trans-thoracic echocardiography was done, demonstrating the presence of a cardiac tamponade. An emergency pericardiocentesis was performed, draining 500 ml of hematic content. Thoracic-abdominal computed tomography showed bilateral pleural effusion and also peritoneal effusion. Laboratory tests were compatible with an inflammatory situation with neutrophilic leukocytosis, alteration of hepatic function, and a plateau elevation of high-sensitivity troponin T. Colchicine was initiated but the evolution of the patient was torpid, making necessary the performance of a pericardial window due to an abrupt increase of pericardial effusion and echocardiographic signs of impending cardiac tamponade. Two chest tubes were inserted due to an increasing bilateral pleural effusion. Serology was positive for Leptospira spp. so doxycycline was initiated. She reported that she had inspected a rice-field the previous month. The patient presented a good response to the treatment, being discharged from hospital completely asymptomatic, with no pericardial effusion and practically resolved pleural effusions. She was evaluated again one month later, with no trace of effusions or symptoms. .

A prospective randomised study of the paclitaxel-coated balloon catheter in bifurcated coronary lesions (BABILON trial): 24-month clinical and angiographic results.

AIMS: Paclitaxel drug-eluting balloons (pDEB) could be an attractive option to minimise side branch (SB) restenosis in bifurcated coronary lesions. We compared angiographic and clinical outcomes with pDEB plus bare metal stent (BMS) versus drug-eluting stents (DES) in de novo bifurcated lesions. METHODS AND RESULTS: This multicentre randomised trial included 108 patients. Sequential main branch (MB)/SB dilatation with pDEB, with provisional T-stenting with BMS in the MB was performed in the pDEB group, and with everolimus DES in the DES group. The primary endpoint was late lumen loss (LLL) at nine months. The secondary endpoint was the incidence of major adverse cardiac events (MACE: death, myocardial infarction, or target lesion revascularisation). In-segment MB LLL was 0.31±0.48 mm in the pDEB group, and 0.16±0.38 mm in the DES group (p=0.15); mean difference was 0.15 mm (upper limit one-sided 95% CI: 0.27 mm; p=0.001; non-inferiority test). LLL in SB was -0.04±0.76 mm in the pDEB group and -0.03±0.51 mm in the DES group (p=0.983). MACE and TLR were higher in the pDEB group (17.3% vs. 7.1%; p=0.105, and 15.4% vs. 3.6%; p=0.045), due to higher MB restenosis (13.5% vs. 1.8%; p=0.027). CONCLUSIONS: pDEB bifurcation pretreatment with BMS implantation in MB showed greater LLL (ns) and increased incidence of MACE compared to everolimus DES. Both strategies showed similar results in the SB.

Torsade-de-pointes in a patient under flecainide treatment, an unusual case of proarrhythmicity.

Flecainide is an antiarrhythmic considered safe in patients who have no structural cardiopathy, and frequently used in the prevention of atrial fibrillation. However, in patients with a history of infarction and/or severe conduction disorders, its proarrhythmicity may be lethal. Torsade-de-pointes type tachycardia is not included as one of these proarrhythmic effects, since the drug's scant action on ventricular repolarization makes this adverse effect very unlikely. We present the case of a patient who, shortly after beginning treatment with flecainide, was admitted because of syncope related to bradyarrhythmias, long QT, and torsade-de-pointes. There have been very few published cases in which one finds such an association between flecainide and this infrequent arrhythmia.
