Although minimally surgically invasive, laparoscopic surgery has yet to be proven safe in patients receiving anticoagulants. Retrospectively, the laparoscopic management of four patients requiring anticoagulation for cardiac valvular prostheses or chronic atrial fibrillation was reviewed with regard to potential hemorrhagic complications. Warfarin was discontinued preoperatively in all cases. Heparin anticoagulation was individualized according to each patient's risk for thrombosis. Laparoscopic cholecystectomy and intraoperative cholangiography were completed in each patient without resulting hemorrhagic complications. The operative management of patients exhibiting cholecystitis may be complicated by anticoagulation therapy required for preexisting conditions/diseases such as cardiac valve prostheses, chronic atrial fibrillation, deep venous thrombosis, and pulmonary embolism. The minimally invasive nature of laparoscopic surgery lends itself well to cholecystectomy required in the face of anticoagulation treatment. This limited initial series of selected patients demonstrates the feasibility and efficacy of laparoscopic cholecystectomy in patients receiving anticoagulants.

Radiofrequency (RF) ablation is a new modality of pennanently curing patients with various tachycardias using radiofrequency energy, a technique evolved in the past decade. RF ablation was performed on 913 patients with different tachyarrhythmias from April, 1994 to July, 1999. There were 491 men and 422 females aged 42 +/- 34 years (range 1 to 76 years). Supraventricular tachycardia (SVT) was present in 462 patients, accessory pathway mediated atrioventricular re-entrant tachycardia (AVRT) in 355 patients (377 accessory pathways) and idiopathic ventricular tachycardia (VT) in 96 patients. Amongst the patients with SVT, 402 had atrioventricular nodal re-entrant tachycardia (AVNRT), 22 had atrial flutter, 20 had ectopic atrial tachycardia and 18 had atrial fibrillation. RF successfully abolished the tachycardia in 400/402 patients (99.5%) with AVNRT, 330/377 (87.5%) accessory pathways in patients with AVRT, 14/22 patients (63.6%) of atrial flutter, 18/20 patients (90%) of atrial tachycardia and 79/96 patients (82.3%) with idiopathicVT. Successful AV nodal ablation with pacemaker implantation was done in 10/18 patients with chronic atrial fibrillation with fast ventricular rate and tachycardia induced cardiomyopathy. AV nodal modulation for atrial fibrillation was tried in the remaining 8 patients and was successful in 4 (4/8). The overall success rate for all arrhythmias was 93.6%, and there was no mortality. At a follow-up of 6.8 +/- 5.4 months, there was a recurrence in 34/420 patients (8%), in whom successful re-ablation was performed. One patient with AVNRT and another with a parahisian pathway developed complete heart block and were given pacemakers. One patient developed inferior wall infarction on the next day post RF. There were 4 patients who had pericardial tamponade necessitating pericardiocentesis and 2 patients developed deep vein thrombosis, which was treated conservatively. Thus RF ablation is an effective, safe and curative therapy for various arrhythmias.

Left atrial myxoma is a benign tumor but it has a high prevalence of important complications. We report a case of a 73-year-old man affected by hypertension and chronic atrial fibrillation admitted to our hospital for pulmonary embolism, that resulted associated with a proximal deep venous thrombosis of the right leg and with an unknown left atrial myxoma.

Antithrombotic medication can be performed by means of heparins (non-fractionated heparin, low molecular heparins) or the pentasaccharide Fondaparinux as well as with oral vitamin K antagonists. The use of a low molecular heparin is initially recommended for the sake of practicability and safety in case of patients suffering from deep venous thrombosis of the leg and pelvis with subsequent long-term oral medication using a vitamin K antagonist (Marcumar) for anticoagulation. The most frequent indications for long-term anticoagulation are deep leg and pelvis thromboses, pulmonary embolism with atrial fibrillation, artificial prosthetic valves and open oval foramen with ischaemic cerebral infarction. In case of patients with chronic atrial fibrillation it is expedient to initiate permanent anticoagulation according to a risk score. For the purpose of controlling oral anticoagulation it is recommended to employ the INR value in place of Quick's value because these data are better comparable. In case of atherothrombotic diseases secondary prevention will always indicate administration of a thrombocyte aggregation inhibitor. In such cases acetylsalicylic acid is recommended as the standard preparation.
