The period of time following the triggering of an ACTION POTENTIAL when the CELL MEMBRANE has changed to an unexcitable state and is gradually restored to the resting (excitable) state. During the absolute refractory period no other stimulus can trigger a response. This is followed by the relative refractory period during which the cell gradually becomes more excitable and the stronger impulse that is required to illicit a response gradually lessens to that required during the resting state.

Coronary artery fistula from the left circumflex to the coronary sinus. (1/174)

A 27-year-old woman, who had received mitral valve repair for mitral regurgitation resulting from infective endocarditis, was admitted for a close examination of abnormal echocardiographic findings in the left atrium. Transthoracic echocardiography showed trivial mitral regurgitation with normal left ventricular contraction and dilatation of the coronary sinus. Auscultation revealed a grade 2 continuous murmur along the left sternal border. Transesophageal echocardiography demonstrated a marked dilatation of the coronary sinus just behind the posterior wall of the left atrium and turbulent blood flow in the dilated coronary sinus. Cardiac catheterization showed no significant step-up of oxygen saturation in the right heart and normal pulmonary artery pressure. Coronary angiography revealed a markedly dilated and tortuous circumflex coronary artery connected to the coronary sinus through a fistula. A left circumflex artery with a fistulous connection to the coronary sinus is extremely rare.  (+info)

Thoracic vein arrhythmias. (2/174)

The thoracic veins are important foci for the genesis of ectopic atrial tachycardia and play a critical role in the pathophysiology of paroxysmal and permanent atrial fibrillation. The pulmonary veins have the highest arrhythmogenic activity and other venous structures (eg, superior vena cava, coronary sinus and ligament of Marshall) have also been shown arrhythmogenic potential. Thoracic veins contain cardiomyocytes with distinct electrical activities and complex anatomical structures. This review summaries the current understanding of the basic and clinical electrophysiology of thoracic vein arrhythmias.  (+info)

Catheter ablation therapy for atrial fibrillation: current advancements in strategies. (3/174)

Curing atrial fibrillation (AF) by catheter ablation has significantly improved patient morbidity and mortality. The circumferential pulmonary vein isolation technique is established as the principal procedure, with a high cure rate and acceptable safety, for paroxysmal AF, but new adjunctive ablation strategies targeting the AF substrates and sources for long-standing persistent/chronic AF have been developed. These new techniques include linear ablation, complex fractionated atrial electrogram guided ablation, dominant frequency map-guided ablation, ganglionated plexi ablation and disconnection of the coronary sinus and superior vena cava to ablate the AF substrates and sources. The long-term usefulness of the established technique and these innovative adjunctive approaches for the treatment of AF remains to be investigated.  (+info)

A novel technique for placement of coronary sinus pacing leads in cardiac resynchronization therapy. (4/174)

A new technique for the placement of left ventricular pacing leads in the tributaries of the coronary sinus (CS) is described. Antegrade visualization of the CS is accomplished by selective coronary angiography, and a hydrophilic 0.032 in. wire is advanced along the CS. This facilitates the advancement of a CS sheath over a multipurpose diagnostic catheter. A hydrophilic angioplasty wire is then utilized for the negotiation of the inferior left ventricular vein and successful placement of the left ventricular pacing lead.  (+info)

Stabilization of the coronary sinus lead position with permanent stylet to prevent and treat dislocation. (5/174)

AIMS: Coronary sinus (CS) leads used for cardiac resynchronization have undergone development in the last years. However, dislocation rate remained high. We explain a simple method to stabilize the CS lead position. METHODS AND RESULTS: Thirty-five patients (11 females, aged 60 +/- 9.2 years) were treated with this method. An over-the-wire left ventricular (LV) pacing lead system was introduced and lodged in the vessel. Then, a stiff stylet was inserted and kept into the CS lead and end of the stylet was cut by a scissor (permanent stylet technique). Pacing and sensing properties of all leads were checked and the guiding sheath was removed. Control echocardiography did not show pericardial effusion. The mean LVpacing threshold was 1.2 +/- 0.8 V and the mean impedance was 625 +/- 143 Omega at the implantation. During follow-up (12.5 +/- 2.5 months), there were no statistically significant changes in pacing threshold and impedance when compared with the implantation measurements. At the last patient visit, the mean LV pacing threshold was 1.1 +/- 0.8 V and the mean impedance was 620 +/- 140 Omega. Impedance measurements did not suggest lead insulation failure. No LV lead dislocations were detected in our 35 cases during the follow-up. CONCLUSION: Permanent stylet technique seems to be a safe and effective procedure to stabilize CS lead position as demonstrated by our 1-year long follow-up results.  (+info)

A novel method of multisite atrial pacing, incorporating Bachmann's bundle area and coronary sinus ostium, for electrical atrial resynchronization in patients with recurrent atrial fibrillation. (6/174)

AIMS: The aim of the study was to assess efficacy and safety of a novel method of multisite atrial pacing, incorporating Bachmann's bundle (BB) and coronary sinus (CS) ostium pacing, which was implemented for the first time in atrial fibrillation (AF) patients with intra-atrial conduction delay. METHODS AND RESULTS: This follow-up study included 97 patients with drug refractory symptomatic AF, sinus node dysfunction, sinus P-wave > or = 120 ms, and normal atrioventricular conduction. Pacing efficacy was assessed on the basis of two main endpoints: successful rhythm control and the absence of documented or symptomatic AF. During the mean 2.3 +/- 0.7 years of follow-up, the survival rate was 99%, pacing maintenance rate 97%, and the need for re-operation 5%. Rhythm control efficacy was 90%, and 14 patients had no evidence of recurrent AF. After implantation, the mean number of anti-arrhythmic drugs used (P < 0.0001), the need for cardioversion (P < 0.01), and the incidence (P < 0.0001) and duration (P < 0.001) of AF-related hospitalizations decreased. P-wave duration with multisite atrial pacing was shorter than during sinus rhythm, BB, and CS pacing (P < 0.0001). CONCLUSION: A novel method of multisite atrial pacing is safe, provides effective long-term rhythm control, and decreases the necessity for adjunctive therapies in patients with refractory AF and intra-atrial conduction delay.  (+info)

Anatomic relations of the Marshall vein: importance for catheterization of the coronary sinus in ablation procedures. (7/174)

AIMS: Our objective was to study the anatomic relations of the human left atrial oblique vein (Marshall vein), particularly of its ostium opening into the coronary sinus, in order to guide ablation procedures related to that vein. METHODS AND RESULTS: The study was carried out in 23 heart-specimens (mean weight 446 +/- 204 g) of individuals whose mean ages were 43 +/- 21 years, 20 males. The coronary sinus was opened longitudinally, exposing the ostium of the tributary veins; the Vieussens valve was looked for, as well as its relationship to the left atrial oblique vein. The diameters of the left atrial oblique vein and the coronary sinus ostia were measured and the distance between them was determined. The left atrial oblique vein could be identified in 20 (87%) of the hearts, while the Vieussens valve was present in 17 (74%) of the specimens (in 16 of which the left atrial oblique vein was identified). In such condition, the vein was adjacent to the Vieussens valve and proximally positioned relative to the coronary sinus ostium in most of them (14/16 cases). The mean diameters of the left atrial oblique vein and of the coronary sinus ostia were, respectively, 1.23 +/- 0.38 and 8.22 +/- 1.88 mm. The mean distance between both ostia was 30.9 +/- 10.2 mm. CONCLUSION: When present, the left atrial oblique vein can be easily recognized, adjacent to the Vieussens valve. The mean distance between the coronary sinus opening and left atrial oblique vein ostium was around 30 mm, independently of the heart weight and the presence of cardiomegaly.  (+info)

Functional bundle branch block and orthodromic reciprocating tachycardia cycle length: do not bet on accessory pathway location. (8/174)

AIMS: To show 2 examples in which the analysis of the effect of bundle branch block on orthodromic reciprocating tachycardia cycle length was misleading. METHODS AND RESULTS: We performed an electrophysiological study in two patients with orthodromic reciprocating tachycardia showing a transition from wide to narrow QRS during tachycardia. Our two cases of left bundle branch block during reciprocating tachycardia using infero-septal pathways show that ventricular to atrial conduction time prolongation may be larger than 30 ms and may be concealed by a shortening of atrial to ventricular conduction time. In the 2 cases, the atrial insertion of the accessory pathway could be successfully ablated from the right atria at the ostium of the coronary sinus. CONCLUSIONS: The observation of the association between left bundle branch block and cycle length prolongation during reciprocating tachycardia may be associated with a successful ablation at the ostium of the coronary sinus.  (+info)

2] Coronary sinus ASDs are believed to arise from developmental failure of formation of the wall between the coronary sinus and the left atrium.. The coronary sinus is a systemic venous structure embryologically derived primarily from the left common cardinal vein that is continuous with the left anterior cardinal vein. Coronary sinus ASDs involve the inferior and anterior interatrial septa at the usual location of the orifice of the coronary sinus. The orifice of the coronary sinus becomes continuous with the left atrial chamber when a defect occurs in the wall separating the left atrium from the coronary sinus. This arrangement allows shunting between the atria.. From the right atrial aspect of the interatrial septum, the defect may consist of the coronary sinus orifice alone or with additional deficiency of atrial septal tissue around the coronary sinus orifice. On the left atrial side, the defect consists of partial or complete unroofing of the coronary sinus, if the entire superior aspect ...
New life-saving treatments for Coronary artery disease in clinical trial on Assessment of Global Myocardial Perfusion Reserve Using Coronary Sinus Flow Measurements
Abstract. Expanded indications for cardiac resynchronization therapy and the increasing incidence of cardiac implantable electronic device infection have led to an increased need for coronary sinus (CS) lead extraction. The CS presents unique anatomical obstacles to successful lead extraction. Training and facility requirements for CS lead extraction should mirror those for other leads. Here we review the indications, technique, and results of CS lead extraction. Published success rates and complications are similar to those reported for other leads, although multiple techniques may be required. Re-implantation options may be limited, which should be incorporated into pre-procedural decision making.. Link to abstract on PubMed. ...
Sudden occlusion of the left anterior descending branch approximately 2 cm. below the ostium of the left circumflex coronary artery in the dogs heart produces a mortality rate of approximately 50 per cent. In dogs weighing approximately 15 kilos surviving more than 24 hours (average 1 week), an infarction is produced which almost invariably measures 5 x 5 cm. on surface. Following coronary sinus obturation such secondary sudden occlusion of the left anterior descending branch is followed either by no infarction or by a reduction in the size of the infarct. The success of the procedure, quite apart from the mortality rate, depends upon the completeness of the coronary sinus obturation. On the other hand, sudden and complete coronary sinus obturation by itself is associated with a high operative mortality and apparently does not affect the mortality rate following subsequent sudden left anterior descending branch occlusion. Partial persistent obturation of the coronary sinus, however, is in ...

Biventricular pacing is a validated treatment for patients suffering from heart failure resistant to medical treatment. However, up to 30% of the patients are non responsive to this strategy using the coronary sinus approach to pace the Left Ventricle (LV).. It has been demonstrated that the magnitude of the improvement was highly dependant on the LV pacing site. The coronary sinus approach rarely offers more than 1 or 2 potential pacing sites. Resynchronisation using a transeptal approach to pace the left ventricle on the cardiology has been shown feasible on small series. We therefore would like to compare these two approached in a randomised prospective study to confirm the hypotheses that endocardial LV pacing by offering multiple choices for the pacing sites reduces the number of non responders and is associated with greater hemodynamic benefit when compared to the conventional coronary sinus approach. ...
To establish whether pressure-volume areas (PVAs) calculated using the maximum time-varying elastance (Emax) have a relation with myocardial oxygen consumption (MVO2) that improves on other indexes of myocardial oxygen demand, we studied nine dogs of either sex weighing 19-39 kg, which were instrumented with a micromanometer left ventricular (LV) catheter and a Wilton-Webster coronary sinus flow catheter and had red blood cells tagged with technetium-99m for radionuclide angiography. Hemodynamics, coronary sinus flow determinations, and radionuclide angiograms were obtained under control conditions and during three to five steady-state loading conditions (mean +/- SD, 5.6 +/- 0.7). Isochronal pressure-volume data points from each pressure-volume loop were subjected to linear regression analysis to calculate Emax. The Emax relations, diastolic curves, and systolic portions of each pressure-volume loop were used to obtain calibrated PVAs. The Emax PVA (mm Hg.ml.beat-1.100 g-1) and MVO2 (ml ...

A device for treatment of mitral annulus dilatation comprises an elongate body having two states. In a first of these states the elongate body is insertable into the coronary sinus and has a shape adapting to the shape of the coronary sinus. When positioned in the coronary sinus, the elongate body is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

The appearance of the proximal descending aorta reflects an aortic spindle - this is an anatomical variant where there is a smooth, mild bulge just beyond the aortic isthmus.
AIMS: Mitral isthmus ablation is technically challenging, often requiring both endocardial and epicardial coronary sinus (CS) ablation. Blood flow in the CS and circumflex artery may act as a heat sink and reduce the efficacy of radiofrequency ablation. This study investigates how the CS and circumflex artery diameters affect mitral isthmus ablation. METHODS AND RESULTS: Thirty-five patients underwent ablation for atrial fibrillation. Irrigated-tip catheters were used during mitral isthmus ablation with the following settings: endocardial surface (maximum power: 40-50 W at the annular end of line; maximum temperature: 48°C); CS (maximum power: 25-30 W; maximum temperature: 48°C). The absence of block after 10 min of endocardial ablation led to CS ablation for up to 5 min. If there was still no block, further ablation was at the discretion of the physician. Coronary angiography and CS venography were performed and analysed with quantitative coronary angiography. Mitral isthmus block was achieved in
This is generally performed subsequent to RV lead placement, with the RV lead providing a backup in case of accidental damage to the electric fibers of the heart, causing an asystolic event. As with the RV lead, a guide wire is first inserted, allowing for the insertion of a multi-delivery catheter. The catheter is subsequently maneuvered to the opening of the coronary sinus in the right atrium. From here a contrast media is injected, allowing the surgical team to obtain a coronary sinus phleobogram to direct the placement of the lead into the most suitable coronary vein.[1]. Once the phlebogram has been obtained, the multi-delivery catheter is used to guide in the lead, from the chosen vein of entry, into the right atrium, through the coronary sinus and into the relevant cardiac vein.[1]. Left ventricular lead placement is the most complicated and potentially hazardous element of the operation, due to the significant variability of coronary venous structure. Alterations in heart structure, ...

Heart failure patients with left ventricular (LV) ejection fractions of ,35% who are on optimal medical therapy with QRS durations of ≥120 ms on surface electrocardiography have derived clinical benefit from cardiac resynchronization therapy (CRT). Although this well-established and guideline-recommended treatment has shown reductions in heart failure progression and risk for ventricular tachyarrhythmias, there are also shortcomings. Nearly one-third of patients with CRT implants fail to show clinical benefit. Although potential explanations for the lack of response to CRT may be multifactorial, one of the most important prerequisites for successful CRT is proper LV lead placement. And that can be technically challenging.. LV lead placement to deliver CRT typically involves cannulating the coronary sinus, performing coronary venous angiography, selecting a target vein, and advancing the pacing lead into the selected vein to achieve adequate resynchronization. Although it is still an evolving ...
Alternative methods are necessary for cardiac resynchronization therapy when coronary sinus lead implantation fails. We aim to describe a fundamentally new approach using transapical implantation of an active fixation endocardial pacing lead. This technique is based on direct puncture of the left ventricular apex using the standard Seldinger technique. The tip of the lead is positioned with intracavital navigation under fluoroscopy. This method offers advantages for cardiac resynchronization because it is minimally invasive, provides endocardial pacing, and does not involve the mitral valve. ...

An implantable defibrillation lead with steerable characteristics, allowing the lead to be more easily placed within the coronary sinus. The lead comprises an elongated lead body having a proximal end and a distal end. Adjacent the distal end, there is an electrode, preferably a coiled defibrillation electrode placed on the exterior of the elongated lead body. The distal end of the lead body has a permanent set or bend. A torque tube, extending through a lumen in the lead body from the proximal end of the lead to an anchor block adjacent the distal end of the lead, can be rotated by a physician to orient the bend in the lead. A cable passes through the torque tube from the proximal end of the lead through the anchor block to the distal end of the lead. This cable is affixed to a wall of the lumen, preferably in the direction of the bend. Pulling on the cable temporarily changes the bend in the distal end of the lead.
All studies were performed in the electrophysiology laboratory. Patients were premedicated with meperidine or diazepam before the procedure. All antiarrhythmic drugs were discontinued for a minimum of five drug half-lives before the procedure. Standard multipolar catheters with 1-cm interelectrode distance were used for pacing and recording of intracardiac electrograms. These were positioned at the high right atrium, His bundle and right ventricular apex. A fourth catheter was positioned in the coronary sinus with one of the electrodes located at the coronary sinus ostium. Stimulation was performed with rectangular impulses using an EP-2 stimulator (EP Medical Inc.). A standard multichannel recorder was used for hardcopy recording. Three surface electrocardiographic (ECG) leads (I, aVF and V1) were recorded at all times. The intracardiac signals were filtered at a bandpass of 30 to 500 Hz and stored on FM tape. The pacing threshold was determined at the high right atrium and coronary sinus ...

Y1 - 2010/8. N2 - The anatomy of a persistent left superior vena cava (SVC) to the left atrium (LA) without the innominate vein can make it challenging to complete intracardiac repair. We reviewed our five cases of the direct end-to-side anastomosis of SVCs to facilitate anatomical repair of SVC-right atrial connection for biventricular repair. Diagnoses were two partial atrioventricular septal defect with left isomerism, one complete atrioventricular septal defect (CAVSD) with left isomerism, one CAVSD without isomerism and one atrioventricular discordance and double outlet right ventricle with right isomerism. Mean age at the operation was 20±23 months (4-58 months) and body weight was 7.8±3.4 kg (4.8-12.7 kg). After completion of intracardiac repair, the SVC to LA was divided and end-to-side ...
CONGENITAL anomalies of the great veins of the neck are relatively infrequent. Persistent left superior vena cava (PLSVC) is an embryologic remnant of the left superior cardinal vein seen in 0.1 to 0.3% of healthy adults.1 PLSVC runs between the left pulmonary veins and the left atrial appendage enlarging the coronary sinus as it enters the atrium. When present, it can affect placement of central catheters, pacemakers, and cardiopulmonary bypass. It is important to be aware of this variation and to recognize it in imaging studies ...
Persistent left superior vena cava (PLSVC) and horseshoe kidney (HSK) are common congenital abnormalities; however presence of both in the same person is extremely rare. A patient with hepatitis C cirrhosis awaiting transplant presented with worsening liver dysfunction, diagnosed with acute renal failure secondary to hepatorenal syndrome, and required X-ray fluoroscopy guided tunneled venous catheter placement for hemodialysis. Review of imaging studies demonstrated coexistence of PLSVC and HSK. PLSVC in adulthood is usually incidental with the most common drainage pattern being without physiologic dysfunction. Isolated horseshoe kidney is still the most common of renal fusion anomalies; however etiology of coexistent PLSVC remains unknown.
© 2016 American College of Cardiology Foundation. Published by Elsevier. Objectives The goal of this study was to assess the contemporary and historical success rates of transvenous left ventricular (LV) lead placement for cardiac resynchronization therapy (CRT), their change over time, and the reasons for failure. Background In selected patients, CRT improves morbidity and mortality, but the placement of the LV lead can be technically challenging. Methods A literature search was used to identify all studies reporting success rates of LV lead placement for CRT via the coronary sinus (CS) route. A total of 164 studies were identified, and a meta-analysis was performed. Results The studies included 29,503 patients: 74% (95% confidence interval [CI]: 72% to 76%) were male; their mean age was 66 years (95% CI: 65 to 67); their mean New York Heart Association functional class was 2.8 (95% CI: 2.7 to 2.9); the mean LV ejection fraction was 26% (95% CI: 25% to 28%); and the mean QRS duration was 155 ms (95%
Mitral isthmus ablation forms part of the electrophysiologists armoury in the catheter ablation treatment of atrial fibrillation. It is well recognised however, that mitral isthmus ablation is technically challenging and incomplete ablation may be pro-arrhythmic, leading some to question its role. This article first reviews the evidence for the use of adjunctive mitral isthmus ablation and its association with the development of macroreentrant perimitral flutter. It then describes the practical techniques of mitral isthmus ablation, with particular emphasis on the assessment of bi-directional mitral isthmus block. The anatomy of the mitral isthmus is also discussed in order to understand the possible obstacles to successful ablation. Finally, novel techniques which may facilitate mitral isthmus ablation are reviewed.
Although CRT is now an accepted therapeutic modality for patients with HF and conduction disturbances, a significant proportion of patients remain nonresponders.1 Our study shows that LV lead location may be a significant contributor to this nonresponsiveness and that pacing the apical region of the LV is associated with a worse clinical outcome, including significantly higher mortality rates. Our results also demonstrate that LV lead location along the short axis (ie, anterior, lateral, or posterior wall) does not influence the primary end points of HF hospitalization and all-cause mortality. This is the first study from a randomized clinical trial to examine the impact of LV lead location on clinical outcome in which venous angiography and LV lead position data were collected prospectively and evaluated independently.. Prior work has recommended that targeting the lateral or posterolateral wall by way of either an appropriate coronary sinus branch or surgical (epicardial) placement is a ...
Infective endocarditis (IE) is a rare disease with high mortality. Right-sided IE accounts for 5-10% of cases of IE. The tricuspid valve is most commonly affected, oppositely in coronary sinus (CS). The diagnoses, treatments and outcomes of CS vegetation has not been summarized yet. We present a 71-year-old man complained of cough and fever. Transthoracic echocardiography revealed the aneurysmal dilated CS with the band medium-echo mobile structure. A sinus venosus atrial septal defect has been detected. He had a persistent left superior vena cava which drained the right atrium via the aneurysmal dilated CS. Blood cultures were positive for Staphylococcus aureus. After intravenous antibiotic therapy, he had the symptom of dyspnea. The suspicious diagnosis is recurrent septic lung emboli which was confirmed by thoracic contrast enhanced computed tomography. The thoracotomy was performed to repair the atrial septum and remove the CS vegetation. Ten days later, the patient was discharged with only mild

However, with the current selection criteria and methods for implanting the pacemaker, only 60-70% of the patients derive significant benefit from the treatment.. New imaging techniques, including advanced ultrasound and computed tomography, in combination with new versatile multi-pole electrodes, have made an individually tailored therapy possible. Using these techniques in combination, the study will investigate the effect of individually based optimal placement of the pacemaker electrodes vs. standard care. The optimal LV electrode position is defined as pacing a viable segment with the latest mechanical delay, targeting a specific segment of the coronary sinus as visualised on cardiac CT. The hypothesis is that this will increase the number of positive responders from 65% to 85%. ...
A 6 month od baby with Wolfgang-Gollop syndrome was catheterized before surgery for tetralogy of Fallot. Echocardiography had revealed bilateral superior vena cava with LSVC draining into a dilated coronary sinus. In order to assess the need for canulating or ligating the persistent left superior vena cava (LSVC) at time of surgery, we inserted an 5 Fr end-hole catheter into the LSVC via the right atrium and coronary sinus. It was then advanced into the left azygos vein and angiography performed. A large communicating vein connecting the 2 asygos veins was seen beind the heart. Persistent LSVC has been described in tetralogy of Fallot. In our case, although no classical communicating wein could be found by echocardiography, selective angiography revealed a peculiar communication between bilateral azygos veins. The baby underwent successful surgical repair with no need for left superior vena cava cannulation during cardiopulmonary bypass ...

N2 - We report the case of a VDD single-lead pacemaker implantation through a persistent left superior vena cava in a 48-year-old male patient with recurrent episodes of syncope due to paroxysmal atrioventricular block. VDD lead insertion through the anomalous venous structure led to positioning of the floating sensing dipole into the coronary sinus, in a very large and stable sensed atrial signal due to the close anatomic relationship between the coronary sinus and the left atrium. Shortness of the sensed atrioventricular interval allowed VDD stimulation to occur only in the case of paroxysmal atrioventricular block.. AB - We report the case of a VDD ...
Definition: In PLSVC, the left brachiocephalic vein does not develop fully and the left upper limb and head & neck drain into the right atrium via the coronary sinus. However, from a morphological point of view, the anatomical drainage of a persistent left superior vena cava is always into the coronary sinus. ...

A 22-year-old girl was admitted to our cardiology institute with Permanent tachycardia in last 6 years for diagnostic assessment and therapy. Doppler echocardiography show structural of heart is normal, ECG revealed a varied resting rate from 120 to 140 bpm, 1:1 AV ratio and long RP interval. P wave morphology was negative on leads I, II, III, aVF, and V4 to V6, positive on lead V1, and diphasic 1 /2 on lead aVL. Electrophysiology (EP) study was performed, Although the exactly mapping was performed in left inferior pulmonary vein and mitral annulus, however, no target point was found ahead of CS1-2, the tried discharge was invalid. The ablation catheter was entered the coronary sinus to guide electrical isolation, curing the tachycardia. The ECG returned to normal sinus rhythm. Through three years follow up, no AT recurrence.
An assembly and method for effecting the condition of a mitral valve annulus of a heart includes a guide wire configured to be fed into the coronary sinus of the heart, and a mitral valve annulus therapy device configured to be slidingly received on the guide wire and advanced into the coronary sinus of the heart on the guide wire. A guide tube may further be employed for guiding the device into the coronary sinus. An introducer which may be employed for pushing the device into or pulling device out of the heart has a mechanism for releasably locking to the device. This enables substitution of the device if needed. Also, the crossover point of the circumflex artery and coronary sinus may be determined and avoided when the device is deployed.
Erondu-Cymet Syndrome, 978-620-0-83887-2, Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Erondu-Cymet syndrome is a syndrome caused by a translocation on the . The genetic for people with this condition is 46, XY, inv(21)(q11.2q22.1). Findings in these patients include: hypotension, hypoxemia, seizures, and impairment of cognitive ability. Patients with this condition may have persistent left superior vena cava that drains into the left atrium, as well as pulmonary arterio-venous malformations. Erondu-Cymet Syndrome was discovered in 2006 by Ugochi Erondu and . In 2000, researchers working on the announced that they had determined the sequence of that make up this chromosome. Chromosome 21 was the second human chromosome to be fully sequenced.

Despite the enthusiasm behind the use of ultrasound to facilitate central venous access, little data exists regarding best practice. Likely, the most popular technique of using ultrasound is the real-time, out-of plane approach in which the IJ is imaged on short-axis. This technique has the distinct limitation in that the needle will cross the ultrasound beam only once, resulting in a short axis cut of the needle. This image may not represent the tip of the needle, but rather the shaft of the needle. If the operator chooses an angle of insertion in which the needle crosses the ultrasound beam posterior to the vein, then they will never see the needle prior to puncture of the vein. Further, in the out-of-plane approach, the operator can have challenges in determining whether the needle is too far lateral or medial with respect to the target vein. These issues are compounded by the tendency of the operator to advance the needle when it is not visualized on the screen (7). With the out-of-plane ...
