A new, smaller balloon catheter now addresses variable patient anatomies as well as physician preferences and provides improved handling and increased balloon stability during PICSO therapy.. "I was able to place the balloon very easily in the coronary sinus and immediately achieved a stable position," says Béla Merkely, chairman and director at the Semmelweis University Heart and Vascular Center in Budapest, Hungary, after using the new PICSO therapy in a STEMI and an NSTEMI patient.. "The system provided continuous and stable therapy during my coronary intervention, and I look forward now to see the long-term benefits for our patients with myocardial infarction," adds Levente Molnár from the Semmelweis University Heart and Vascular Center.. The PICSO impulse systems console and software also have been updated to facilitate faster, safe, and effective therapy delivery. Piers Clifford, cardiology consultant and clinical lead for Cardiology, Buckinghamshire Healthcare NHS, who used the new ...
Drawn from more than 1,900 patients undergoing unprotected LM PCI, the present analysis represents the largest study to assess the impact of operator experience on clinical outcomes after LM PCI. The main findings of our study are as follows: 1) patients treated by experienced, high-volume operators have a significantly reduced risk for cardiac death at short- and long-term follow-up after LM PCI, despite having more extensive and complex coronary artery disease at baseline; 2) operator experience was a strong independent predictor of cardiac death after LM PCI; and 3) incorporating operator experience and volume in an already validated stratification model such as the SYNTAX score and the SYNTAX score II improved the discrimination capability of these score algorithms.. PCI is an alternative to CABG for patients with LM disease who have low (1,2) or intermediate (3,4) SYNTAX scores and/or lesion anatomy that is deemed suitable for PCI (1,2,5). LM PCI is also a good alternative for patients with ...

The map is the most technologically advanced and demanding part of the procedure. It is created with the help of a specialized supercomputer called Carto. Carto is, in many ways, like a miniature GPS that communicates with electronics in the catheters to build a real-time, 3-dimensional picture of the heart. This 3D map includes detailed color coding and animated aspects to depict the hearts electrical circuit speed and direction as well as the health of the underlying heart cells. After performing this stage of the EP Study, we are able to treat with ablation. During the ablation phase, Carto tells Dr. Gidney precisely where the catheter is to within 1mm as well as detailing the force with which he is pushing on the heart, the heat at the tip, and when the area has been treated effectively and safely.. The entire procedure can take as little as 1 hour, but often as long as 4 or more hours depending on the scope of the ablation and the origins of the irregular heart rhythm. Often Carto helps to ...
Catheter-driven cardiac interventions have emerged in response to the need of reducing invasiveness associated with the traditional cut-and-sew techniques. Catheter manipulation is traditionally performed under real-time fluoroscopy imaging, resulting in an overall trade-off of procedure invasiveness for radiation exposure of both the patient and clinical staff. Our approach to reducing and potentially eliminating the use of flouroscopy in the operating room entails the use of multi-modality imaging and magnetic tracking technologies, wrapped together into an augmented reality environment for enhanced intra-procedure visualization and guidance. Here we performed an in vitro study in which a catheter was guided to specific targets located on the endocardial atrial surface of a beating heart phantom. "Therapy delivery" was modeled in the context of a blinded procedure, mimicking a beating heart, intracardiac intervention. The users navigated the tip of a magnetically tracked Freezor 5 CRYOCATH ...

Story written 2014. Dions heart condition was diagnosed at my detailed scan, where they said he would need three stages of operations which would help him but never cure him.. Dions first operation was done at a day old and he spent four weeks at Birmingham Childrens hospital before he was allowed home. He had only been home a couple of months when he got septicemia and a blood clot in his heart, which required another operation.. Dions second stage operation was done when he was around six months old. This went to plan and he was home a few weeks later and continued to do well. He had to undergo several cardiac catheters (camera to look at his heart) every so often to check things was going ok.. Around the age of 1 he had to have another operation to try and widen his aortic arch and after several attempts it worked.. Dions fifth operation was in 2007 he was aged 7. This was the third stage called a Fontan and we were in hospital for six weeks due to him needing to go on a special diet. He ...
Guideliner should be advanced all the way into the coronary artery over the Rota sheath/burr, then forcefully pull the burr. Other approach could be tried is to advance the another guide Cather by additional access and try to advance a guidewire and a small balloon alongside the burr; If successful then gradually dilate with PTCA balloon at the level of stuck burr which will then allow burr to become free and to be pulled out safely. We have tried this approach 3 times in the past and always failed to advance the guidewire alongside the burr as burr is deeply entrapped in the artery. If all these maneuvers still fails, then last option will be to send pt for CT surgery to remove the burr openly.. ...

Using a variable stiffness guidewire to cross a stenosed region of a patients vasculature by advancing the distal end of the guidewire to the stenosed region, reducing the flexibility of the distal end of the guidewire, and further advancing the distal end through and past the stenosed region of the lumen. The variable stiffness guidewire has a longitudinally movable core member with a proximal end and a shapable distal end, a compressible body is slidably mounted on the core member, with one end of the compressible body secured to the end of the core member, and a tubular support member is disposed about the core member with a distal end that abuts the proximal end of the compressible body. The guidewire further comprises a tensioning means at the proximal end to move the core member longitudinally with respect to the tubular support member so as to compress and reduce the flexibility of the compressible body.

Background: With the improved lifestyle of people, the incidence of coronary artery disease is gradually increasing. Approximately 15% - 20% of patients undergoing diagnostic catheterization had one or more chronically occluded coronary arteries. Method: The patients who were diagnosed with chronic total occlusion (CTO) in our hospital within one year period have been included. They were initially divided into two groups based on angiographic reports: single vessel disease (SVD) and non-single vessel disease (non-SVD) group, then into optimal medical therapy (OMT) group, percutaneous coronary intervention (PCI) group and coronary artery bypass graft (CABG) group. Finally, PCI group is further divided into PCI of CTO lesion (CTO PCI group) and PCI of non-CTO lesion (non-CTO PCI group). Results: A total of 261 patients were enrolled as CTO patients, mean age was 62.83 years, 70.1% were male patients. The incidence rate of common risk factors was hypertension (64.4%), followed by smoking (48.3%), diabetes
Percutaneous mitral valve repair (MVR) is used to treat mitral regurgitation (MR; depicted in the image below).

Increased interest focusing on coronary chronic total occlusions has emerged since several studies have proven improved cardiovascular outcomes and quality of life after successful chronic total occlusion (CTO) revascularization. CTO of an epicardial coronary artery is one of the leading challenging complex lesion type when percutaneous coronary intervention (PCI) is indicated.
During the study period, 24,701 procedures were performed by 2,339 operators. Of these, 11,846 were performed by 1,792 new operators who first performed carotid stenting after the Centers for Medicare and Medicaid Services national coverage decision. Overall, 30-day mortality was 1.9% (n = 461), and rate of failure to use an embolic protection device was 4.8% (n = 1,173). The median annual operator volume among Medicare beneficiaries was 3.0 per year (interquartile range, 1.4-6.5), and 11.6% of operators performed 12 or more procedures per year during the study period. Observed 30-day mortality was higher among patients treated by operators with lower annual volumes (2.5% [95% confidence interval {CI}, 2.1%-2.9%], 1.9% [95% CI, 1.6%-2.3%], 1.6% [95% CI, 1.3%-1.9%], and 1.4% [95% CI, 1.1%-1.7%] across the four categories; p < 0.001) and among patients treated early (2.3%; 95% CI, 2.0%-2.7%) versus late (1.4%; 95% CI, 1.1%-1.9%; p < 0.001) during a new operators experience.

Definition : Catheters designed for insertion into the vascular system that are long enough to advance and locate their distal tip in the heart and/or the pulmonary or coronary arteries. These catheters usually include distal tips that may be tapered and curved proximal ends bonded to hubs or connecting devices. The distal tips can be modified by attaching balloons or sensing devices or by placing holes for injection of contrast medium. Vascular catheters may be stiff or flexible and ideally would be nonthrombogenic, strong, flexible, and biocompatible, and they must retain their preshaped tip configuration (i.e., have memory) while permitting torque control. Most cardiac catheters are made of polymers (e.g., silicone elastomer, polyurethane) and may also include metals (e.g., stainless steel). Cardiac catheters are used in therapeutic (e.g., ablation, valvuloplasty) and diagnostic (e.g., angiography, cardiac output measurement) procedures..

I remarked to the techs how my grandmother had made do with the old fiber optic shape sensing and localization to track positions of the surgical tools inside the patient. I saw how they rolled their eyes as if I said that every time I came in to guide surgery. As my gloved fingers remotely manipulated the laser scalpel with its flexible whisker wire, I thought of Grandma and her primitive sensors on guide wires and catheters inside the patient for as long as three hours. My pinkie eased the flexible catheter down the artery as it stretched around intervening organs. I zeroed in on the occlusion and thought how far minimally invasive surgery had gone. I vaporized the occluding plaque without allowing it to dislodge. I retracted the flexible catheter and laser scalpel, each much thinner than a hair. I shuddered as I recalled the old cardiac catheters in the Mayo Museum, huge pipes up to 3 millimeters in diameter ...

A method of calibrating a robotic device, such as a cardiac catheter, includes oscillating the device on an actuation axis by applying an oscillation vector at an oscillation frequency. While oscillating, a location of the device is periodically measured to generate a plurality of location data points, which may express the location of the device relative to a plurality of measurement axes. The location data points are then processed using a signal processing algorithm, such as a Fourier transform algorithm, to derive a transfer function relating a position of the device to a movement vector for the actuation axis. The transfer function may be resolved into and expressed as a calibration vector for the actuation axis, which may include one or more components, including zero components, directed along each of the measurement axes. The process may be repeated for any actuation axes on which calibration is desired.
After an atrial fibrillation (AF) ablation, one in 20 patients experience a periprocedural complication and nearly one in 10 are readmitted within 30 days, according to research published Jan. 10 in the Journal of the American College of Cardiology. The researchers assessed the factors of these readmissions, finding operator experience, age and sex, among others, to be independent predictors.

Percutaneous mitral valve repair using the MitraClip (Abbott Vascular, Santa Clara, California) is a promising technique to treat symptomatic severe mitral regurgitation (MR) in patients at high or prohibitive surgical risk. Large observational registries of patients treated with this device for predominantly secondary MR show symptomatic relief and improvement of hemodynamics at rest (1,2). Comparative data on exercise hemodynamics before versus after percutaneous mitral valve repair therapy are currently lacking, although such data are most relevant in secondary MR. First, secondary MR is characteristically dynamic and sensitive to changes in ventricular geometry and loading conditions (3). It remains unclear whether, besides a reduction in resting MR, percutaneous mitral valve repair therapy is effective in reducing secondary MR during exercise. Second, mitral valve area is typically reduced following the procedure (4). It remains to be determined whether such mild iatrogenic stenosis might ...
Methods and Results-This study includes the first 200 paroxysmal atrial fibrillation patients treated with the VGLA catheter (33 operators, 15 centers). After transseptal puncture, the VGLA catheter was used to perform PV isolation. Electric isolation was assessed using a circular mapping catheter. Using the VGLA catheter, 98.8% (95% confidence interval, 97.8%-99.5%) of targeted PVs were isolated using a mean of 1.07 catheters per patient. Fluoroscopy and procedure times were 31±21 (mean±SD) and 200±54 minutes, respectively, and improved with operator experience. There were no instances of stroke, transient ischemic attack, atrioesophageal fistulas, or significant PV stenosis. There was a 2% incidence of cardiac tamponade and a 2.5% incidence of phrenic nerve palsy. At 12 months, the drug-free rate of freedom from atrial arrhythmias after 1 or 2 procedures was 60.2% (95% confidence interval, 52.7%-67.4%).. ...
0006]For AFL mapping procedures (as well as for some AF procedures), it is important to map the electrical activity in both the coronary sinus (CS) and the right atrium (RA), especially the region of the high right atrium (HRA). Currently, to map both the CS and the RA, a pre-shaped, non-steerable, mapping catheter having two sets of electrodes is inserted through a jugular vein at the base of the patients neck, through the superior vena cava (SVC), and into the RA, where it bends (or "banks") off of the lower portion of the atrial chamber (i.e., over the isthmus region) and into the CS. While functional for mapping the respective RA and CS, this type of catheter has certain drawbacks. For example, because it passes across the lower atrial chamber, maneuvering the mapping catheter for achieving proper electrical contact in the HRA can be difficult. Further, since most ablation catheters used for AFL and AF interventional procedures are inserted through the groin and inferior vena cava (IVC), ...
The study is the largest in the United States to examine the safety and effectiveness of a so-called retrograde approach to angioplasty and stenting of chronic total occlusions (CTOs). Using this innovative technique, interventional cardiologists at three medical centers were successful in tunneling through the obstruction, opening the blocked artery and restoring blood flow to the heart in about 80 percent of patients, many of whom had no alternative treatment options.. "Patients with chronic total occlusions experience chest pain, shortness of breath and other disabling symptoms," said Tesfaldet T. Michael, MD, a cardiology research fellow at the University of Texas Southwestern Medical Center inDallas. "When medical therapy fails, percutaneous coronary intervention (PCI) may be the last resort. It really helps patients to have a better quality of life.". Up to one-third of patients who undergo diagnostic angiography have cholesterol plaque that completely blocks a coronary artery. If they ...
The reverse CART technique provides the potential to modify the retrograde procedure by improving the controlled movement of the retrograde wire and improve the success rates of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Development of interventricular hematoma is a rare complication of CTO PCI. A 63-year-old man with effort angina with a right coronary artery CTO lesion underwent PCI by retrograde approach from the LAD to a septal branch. A contrast "stain" was demonstrated surrounding the septal collateral channel used for the retrograde approach at the end of the procedure without symptom ...
3). Puncture is done ~2 finger-widths proximal of the wrist. The median nerve is located in the middle of the lower arm. The radial artery has a diameter of 2 to 3 mm (Fig. 4). 5 mm) - Learning curve for operators - Limited sheath diameters (≤ 7F) - Tendency for vasospasms Fig. 4 Puncture of the radial artery. , EMLA cream) ~30 minutes before puncture (Fig. 5). The forearm is supinated, and the hand is dorsally extended at the wrist. Splints are available that help keep the hand in this position. Occasionally a marked kinking of the iliac arteries or aorta can impede the control of the catheter and correct placement of the catheter. The operator can then use the radial artery as an alternative. This problem usually cannot be predicted and is only recognized during the first catheterization via the femoral artery. Further reasons to choose the brachial or radial artery for access are inflammatory skin conditions or marked scarring in the groin. As noted, an essential advantage of the nonfemoral ...
Introduction: Limited data are available on safety and efficacy of second-generation cryoballoon (CB2) for cryoablation of atrial fibrillation (CBA).. Hypothesis: To evaluate in a large cohort of patients treated in real world clinical settings, demographics, procedural data and outcomes comparing CB2 to first-generation cryoballoon (CB1).. Methods: Between 2012 and 2014, 581 patients (74% men, 59±10 years, 78% paroxysmal AF, LA diameter: 41±6 mm) suffering from AF and undergoing pulmonary veins (PV) CBA were prospectively enrolled in ClinicalService® framework One Shot TO Pulmonary vein isolation (1STOP) project. The cohort was divided into 2 groups according to the cryoballoon used in standard clinical practice: 120 (21%) CB1 and 461 (79%) CB2.. Results: Clinical and demographic characteristics were similar in the two cohorts; procedure, fluoroscopy and ablation time were significantly lower in CB2 respect to CB1 (141±40 vs 166±50 min, p,.001; 35±15 vs 41±15 min, p,.001; 27±17 vs ...
The right renal vein, along with the left renal vein, makes up the renal veins that drain the kidneys. They attach the inferior vena cava to the kidney. The right renal vein is smaller than the left. It begins at the hilum of the kidney where three to six tributaries meet. These veins are behind the renal arteries. This goes against most other relationships between veins and arteries in the abdomen. Continue Scrolling To Read More Below... ...
The present invention is a catheter device that includes a disruptable guidewire channel. The guidewire channel is configured to provide necessary trackability of the catheter along the guidewire during introduction of the catheter to a treatment site. Once treatment is completed, the guidewire channel can then be disrupted so as to free the guidewire from the catheter in situ. The apparatus of the present invention provides distinct advantages over existing over-the-wire and rapid exchange catheter introduction methods, including the ability to achieve much faster treatment implement exchanges, the ability to rapidly deliver multiple treatment implements in series, and the ability to maintain multiple treatment implements simultaneously at a treatment site using a single guidewire.
A dual lumen guidewire support catheter for accurately crossing a chronic total occlusion in a vessel is disclosed. The dual lumen guidewire support catheter includes a first lumen portion and a second lumen portion sharing a common side and a common distal end. The first lumen portion can be a rapid exchange or over-the-wire portion, while the second lumen portion is an over the wire portion. One or both of the portions can include a discontinuity to enable removal of a guidewire following placement through or at an occlusion or lesion.

Prior to participation in the cohort-study each EP center had to perform a minimum of 50 RF or 50 cryoballoon approaches. To insure the consecutiveness of recruitment, participating centers have to announce the intention to ablate the patient prior to the procedure to the coordinating center in Ludwigshafen. After inclusion of 500 patients with well accepted criteria for AF ablation undergoing cryoballoon pulmonary vein isolation (PVI) in experienced german EP centers inclusion of patients will be extended to european centers. A total of 4.000 patients will be included in the cohort-study, 2.000 in both the cryoballoon and the RF arm ...
A guidewire useful for feeding a medical catheter through a body duct network to a distant target site within the body has a flexible distal portion. The distal portion facilitates threading the guidewire in a tortuous path through acute bends at branch junctions in the duct network. The guidewire end is able to feed into very delicate vessels such as ventricles of the brain and the spinal canal without puncturing the walls or damaging organs. The novel guidewire includes beads displaced longitudinally at the distal end of a core wire. The beads are separated by a gap distance. The core wire can flex at points within the gaps between beads which allows the dial end of the guidewire to bend at branch junctions and to conform to the curvature in the vessel duct. The beads can be fixed to the core wire or they can move freely along the distal portion. Also, beads freely sliding along the core wire can be compressed against each other to control the degrees of stiffness and curvature of the distal portion
DENVER -- Cryoablation for atrial fibrillation appears to be highly dependent on operator experience for patient outcomes but not for safety, researchers found.
The pull type models are built with the same durability as our forwardfacing models. Rather than having to look over your shoulder to guide the blower around objects, the pull type blower follows the path of your tractor. This action keeps the operator driving away from the blown snow, increasing visibility and creating a better operator experience.. A 3PH pull type snow blower can be equipped with an optional hydraulic scraper. Equipped with corner markers so you always know its position, the scraper allows you to pull snow away from doorways and structures so you dont miss a thing..

Iatrogenic ATs have been reported after either surgical or catheter ablation of AF.7-14 After ablation of paroxysmal AF (wherein the initial ablation procedure is predominantly directed to PV isolation), the mechanism of AT is virtually always focal, originating from reconnected PVs.10 However, ablation of persistent AF typically involves LA, and sometimes RA, "substrate" ablation (linear lesions and ablation of sites of complex fractionated electrograms) beyond simple PV isolation. Here, we report a novel approach to mapping these postablation scar-related ATs by using a combination of activation mapping with a multielectrode array mapping catheter and targeted entrainment mapping.. The mechanisms of postablation ATs depend to a large extent on the ablation performed in the index procedure. A segmental approach to PV isolation, confirmed with a circular mapping catheter, resulted in most postablation ATs being of a focal mechanism from reconnected PV ostia.10,12 Anatomic approaches have been ...

In the 518 patients treated between 2005 and 2010, a 20-polar Lasso catheter (Biosense Webster, Diamond Bar, California) was placed in the LA to map signals before and after ablation at the ostial sides of PVs. Starting in 2010, the Achieve mapping catheter (Medtronic) was employed instead to enable mapping during and after each freezing procedure (n = 87). Freezing times were 2 × 360 s for each vein, 3 × 300 s for left superior (LS) PVs.. Sustained PVI was confirmed 30 min after the initial isolation. For difficult verifications, namely, because of large far-field potentials of the LA, exit block was confirmed by pacing within the PV ostium monitored with the Lasso or Achieve catheter. In 53 patients in the early cohort, touch-up of remaining gaps was performed with the 8-mm tip Freezor MAX focal cryoablation catheter (Medtronic Cryocath). In all later patients, residual potentials were eliminated with additional balloon freezes.. Post-ablation treatment was as described previously (4). ...

With the transilluminated powered phlebectomy treatment, which is a relatively new treatment for varicose veins, an intense light will be used to see the patients vein anatomy. The device used for this treatment allows doctors to suction out the length of the vein through one or two incisions, which saves a great deal of time and means that scarring will be less likely. It is important that you work together with your doctor in order to determine which particular treatment is going to work best for you and your condition. It is also important, once the treatment has been implemented, that you keep them abreast of your condition and let them know whether or not you are making improvement. ...
