Definitions
- This invention relates generally to methods and systems for treatment of atrial fibrillation and other cardiac arrhythmias and, in particular, to methods and systems utilizing 3D digital images for cardiac interventional procedures in such treatment and for the planning of such procedures.
- Heart rhythm problems or cardiac arrhythmias are a major cause of mortality and morbidity.
- An example of different rhythm problems encountered in clinical practice include atrial fibrillation (AF), cardiac arrest or sudden cardiac death (SCD) due to ventricular tachycardia/ventricular fibrillation (VT/VF), atrial flutter and other forms of atrial and ventricular arrhythmias.
- AF atrial fibrillation
- SCD sudden cardiac death
- VT/VF ventricular tachycardia/ventricular fibrillation
- atrial flutter other forms of atrial and ventricular arrhythmias.
- cardiac electrophysiology has evolved into a clinical tool to diagnose these cardiac arrhythmias.
- multipolar catheters are positioned inside the heart and electrical recordings are made from the different chambers of the heart.
- Arrhythmias can be initiated in the laboratory using programmed electrical stimulation.
- Atrial fibrillation is dysrhythmia of the atria or the upper chambers of the heart in which the atria stop contracting as they begin to fibrillate or quiver. Atrial fibrillation is the most common sustained arrhythmia encountered in clinical practice and, recent data suggests, the most common arrhythmia related cause of hospital admissions. Estimates indicate that 2.2 million people in the United States alone have AF and that 160,000 new cases are diagnosed every year. Patients with AF have a high incidence of such complications as stroke, and heart failure and bear an ominous prognosis of higher overall and cardiovascular mortality.
- premature atrial contractions can act as triggers and initiate paroxysms of AF. These premature ectopic beats have been shown to originate predominantly in the pulmonary veins. Inability to reproducibly identify the precise location of these trigger sites limits catheter ablation of trigger sites of AF. Because of the critical role of the pulmonary veins in the generation of AF, and as infrequent and nonreproducible premature atrial contractions limit the utility of trigger site ablation, a variety of surgical and nonsurgical catheter ablation techniques have been used to isolate the pulmonary veins from the left atrium. Intraoperative complete isolation of the pulmonary veins using various energy sources in patients undergoing open heart surgery has led to successful termination of AF in over 80% of patients.
- SCD Sudden cardiac death
- VT is reentry associated with myocardial scarring.
- these reentrant circuits are quite broad because of the nature of the scarring.
- the success rate of VT ablation would increase considerably if it were possible to interrupt these broad reentrant circuits using lesions transecting these circuits. This would require: 1) precise identification of the margins of scarring, 2) the ability to identify and return precisely to areas of interest and, 3) the ability to visualize the lesion lines created.
- a method allowing precise anatomical delineation of the ventricle would make this possible.
- Atrial flutter Several other arrhythmias such as atrial flutter, atrial tachycardia, and tachycardia involving accessory connections between the atria and ventricles are also extremely common and cause significant morbidity and some risk of higher mortality.
- the mechanism of atrial flutter has also been identified. Ablation between the tricuspid annulus and inferior vena cava, forming an anatomical barrier around the flutter circuit, can terminate atrial flutter. Precise identification of this anatomy would thus help significantly.
- precise location and identification of areas such as the crista terminalis in the right atrium, which is a common source of atrial tachycardia, would be useful.
- a number of new techniques are aimed at improving the resolution and acquisition of cardiac activation maps during electrophysiology studies. Although helpful in many instances, inability to accurately relate electrophysiologic information to a specific anatomical location in the heart limits their ability to treat complex arrhythmias such as AF, VT and other arrhythmias.
- the image created is not an exact replication of the anatomy of specific locations in the cardiac chamber. Degree of resolution of the image is totally operator-dependent and limited by the time available to acquire data points.
- CT imaging is a fast and accurate way to delineate the anatomy of any organ.
- MRI magnetic resonance imaging
- x-ray systems The ability to collect volumes of data at short acquisition times allows for 3-D reconstruction of images resulting in true depictions and more understandable anatomic images.
- mapping and ablation catheters need to be navigated to the appropriate sites for successful results during the intervention procedure an to avoid complications such as perforation of the heart during the procedure as the exact orientation and location of the catheter is not possible in a still image.
- One aspect of this invention provides a method for treatment of a heart arrhythmia, preferably atrial fibrillation, in a patient using 4D imaging.
- the method has the steps of (1) obtaining cardiac digital data from a medical imaging system utilizing an electrocardiogram (ECG) gated protocol; (2) generating a series of three-dimensional (3D) images of a cardiac chamber and its surrounding structures from this cardiac digital data, the data being gated at select ECG trigger points having correspondence with different phases of the cardiac cycle; (3) registering these 3D images with an interventional system; (4) acquiring ECG signals from the patient in real-time; (5) transmitting these ECG signals to the interventional system; (6) synchronizing the registered 3D images with certain corresponding trigger points on the transmitted ECG signals such that a 4D image covering the different phases of the cardiac cycle is generated; (7) visualizing this 4D image upon the interventional system in real-time; (8) visualizing a catheter over the 4D image also upon the interventional system; (9) navigating the catheter within the cardiac chamber utilizing the 4
- the medical imaging system is a computer tomography (CT) system. Also preferred is where the imaging system is a magnetic resonance imaging (MRI) system or one utilizing ultrasound. Most desirable is where the method also includes the step of visualizing the 4D image over a computer workstation of the interventional system.
- CT computer tomography

- the method also includes the step of visualizing the 4D image over a computer workstation of the interventional system.
- the 3D images are of the left atrium and pulmonary veins. More preferred is where the catheter is one adapted for mapping and ablation. Most preferred is where the step of generating 3D images from the cardiac digital data uses a protocol optimized for 3D imaging of the left atrium and pulmonary veins.
- interventional system is a fluoroscopic system.
- embodiments having the additional step of continuously updating and adjusting the synchronization of the registered 3D images with the trigger points on the transmitted ECG signals during an interventional procedure are also highly desired.
- Another aspect of this invention finds a system for providing treatment of a heart arrhythmia in a patient.
- This system has a medical imaging system for obtaining cardiac digital data utilizing an electrocardiogram (ECG) gated protocol; an image generation system for generating a series of three-dimensional (3D) images of a cardiac chamber and surrounding structures from the cardiac digital data at select ECG trigger points that correspond to different phases of the cardiac cycle; an ECG monitor for acquiring ECG signals from the patient in real-time and for transmitting these ECG signals to an interventional system; a workstation for registering the 3D images with an interventional system and for then synchronizing these registered 3D images with trigger points on the transmitted ECG signals to generate a 4D image that is visualized upon the interventional system in real-time; and a catheter apparatus for treating heart tissue within the cardiac chamber at select locations, the catheter apparatus having a catheter visualized upon the interventional system over the 4D image.

- the drawings illustrate embodiments of a system and method for treating heart arrhythmia in a patient using 4D imaging in accordance with this invention.
- the embodiments shown enable an electrophysiologist, cardiologist and/or surgeon to plan in advance and to later perform an interventional procedure such as atrial fibrillation ablation in a manner that makes the procedure simpler and more efficacious while decreasing the risk of complications.
- 3D images are obtained of a cardiac chamber such as the left atrium and its adjacent pulmonary veins. These images include detailed 3D models and endocardial views (i.e., navigator or views from the inside) of the chamber.
- a mapping/ablation catheter may be seen over these images so that the practitioner can navigate the catheter to strategic locations within the left atrium such as the left atrial-pulmonary vein junctions in a manner where the orientation and location of the catheter is better understood to avoid complications such as perforation of the heart during the procedure.
- FIG. 1 an schematic overview of an exemplary system 10 for treatment of a heart arrhythmia in a patient in accordance with this invention.
- System 10 includes CT imaging system 12 having a scanner 14 and a first ECG monitor 16 that outputs ECG trigger points corresponding with different phases of the cardiac cycle to scanner 14 through a scanner interface board 18 utilizing a ECG gated protocol.
- a suitable example of scanner interface board 18 is a Gantry interface board.
- Scanner 14 therefore utilizes ECG-gated acquisition to image the heart at different phases of the cardiac cycle such as when the heart is free of motion and its diastolic phase, as well as in multiple phases of systole and early diastole.
- Scanner 14 outputs cardiac digital data 20, including ECG signal time-stamps associated with such data generated by the gating protocol, to image generation system 22.
- Image generation is performed using one or more optimized 3D protocols for automated image segmentation of the cardiac digital data for the left atrium and such surrounding structures as the pulmonary veins.
- a series of gated 3D images 24 corresponding to the selected ECG trigger points are thus generated having quantitative features of the left atrium such as its contour, orientation and thickness as well as providing endocardial or
- 3D images 24 may be in any one of several formats, including but not limited to: a wire mess geometric model, a set of surface contours, a segmented volume of binary images, and a DICOM (Digital Imaging and Communications in Medicine) object using the radiation therapy DICOM object standard.
- 3D images 24 are exported from image generation system 22 and registered with workstation 26 of fluoroscopic system 28.

- Workstation 26 includes patient interface unit 34 that places ECG signals 30 in communication with 3D images 24.
- Interface unit 34 is a processing unit that analyzes
- FIG. 2A A detailed 3D model of the left atrium and the pulmonary veins, including endocardial or inside views, is seen in FIG. 2A.

- Catheter 38 is continuously localized on fluoroscopic system 28 whereby catheter 38 is visualized over 4D image 40. Having catheter 38 seen over 4D image 40 in real-time enables the practitioner to safely and accurately navigate catheter 38 in real-time to the appropriate sites within the left atrium and its surrounding structures where radio- frequency energy can be delivered to ablate heart tissue in treatment of atrial fibrillation.
- FIG. 2B illustrates localization of a standard mapping and ablation catheter over an endocardial view of the left atrium registered upon an interventional system.
- FIG. 3 illustrates a schematic overview of the method for treating a heart arrhythmia using 4D imaging in accordance with this invention.
- the CT scanning system is used to obtain cardiac digital data.
- the CT imaging system is automated to acquire a continuous sequence of data of the patient's heart.
- a shorter scanning time using a faster scanner and synchronization of the CT scanning with a gated ECG signal of the patient at select trigger points reduces the motion artifacts in a beating organ like the heart and provides displacement profiles of the heart at different phases of the cardiac cycle.
- the ability to collect a volume of data in a short acquisition time allows reconstruction of cardiac images in more accurate geometric depictions, thereby making them easier to understand.
- step 120 the data-set acquired by the CT imaging system is segmented and a series of 3D images of the left atrium and surrounding pulmonary veins is generated using protocols optimized for those structures.
- the 3D images identify and visualize the desired views of the left atrium at select points within the cardiac cycle.
- the 3D images are then exported and registered with an interventional system such as one using fluoroscopy.
- the transfer of 3D images, including 3D model and navigator views, can occur in several formats such as DICOM format or object and geometric wire mesh model.
- the registration method transfonns the coordinates in the CT images into the coordinates in the fluoroscopic system. Information acquired by the CT scanning system will in this manner be integrated in real-time with imaging of the left atrium by the fluoroscopic system. Once these coordinates are locked in between the 3D images and the fluoroscopic views, the 3D models and navigator views can be seen from different perspectives on the fluoroscopic system.
- ECG signals are acquired from the patient at the time of the interventional procedure.
- step 180 the interface unit analyzes the ECG signals received and synchronizes these signals with the gated 3D images to generate a 4D image.
- Several trigger points are recognized on both the real-time ECG and the ECG time-stamped 3D images and a zero time differential between these values is calculated.
- this 4D image comprising multiple views of the left atrium can then be viewed sequentially in synchronization with the various phases of the cardiac cycle in real-time on the interventional system.
- the synchronization of the 3D images with the real-time ECG signals is continuously updated and adjusted during the interventional procedure.
- the invention further involves the location of a mapping/ablation catheter over the fluoroscopic system and, in particular, over the registered 4D image of the left atrium and surrounding structures. The catheter is then navigated to the appropriate site within the left atrium in a less risky and efficient manner to perform the necessary ablation procedure in treatment of the patient's arrhythmia.
- FIG. 4 is an example of 3D images depicting relaxation (diastole) and contraction (systole) of the left ventricle.
- the different displacement profiles are shown synchronized to a ECG signal where different trigger points are shown as small lines transecting the different phases of the cardiac cycle as shown by the horizontal line.
