摘要：
A method and system for performing pulmonary vein isolation, mapping, and assessing pulmonary vein occlusion using a single device. The device may generally include an ablation element, such as a cryoballoon, and a sensing component slidably disposed within a lumen of the device and bearing one or more mapping electrodes and one or more pressure sensors. The method may generally include mapping cardiac electrical signals within a heart and/or pulmonary vein, positioning a distal portion of the sensing component within a pulmonary vein, advancing the ablation element until it is in contact with the pulmonary vein ostium, recording blood pressure measurements within the pulmonary vein with the one or more pressure sensors to assess pulmonary vein occlusion, and activating the treatment element when the pulmonary vein is completely occluded. The sensing component may have a straight or hooped configuration, or a configuration therebetween.
