Abstract
Coronary artery fistula (CAF) is characterized as a congenital or acquired abnormal communication between a coronary artery and any of the four chambers of the heart (coronary-cameral fistula) or great vessels (coronary arteriovenous fistula) bypassing the capillaries within myocardium. CAF is a rare disease, challenging to diagnose and treat depending on the anatomical location and type of the fistula and accompanying diseases. This study aims to report a case with multiple coronary artery to coronary sinus (CS) fistulas with giant left circumflex artery and multivalvular infective endocarditis.

Abstract
INTRODUCTION With the entry of pulsed-field ablation (PFA) into electrophysiology, new possibilities for ablation of different substrates such as epicardial foci of premature ventricular contractions (PVCs) from coronary venous system (CVS) have been opened. METHODS This article focuses on a case of a 27-year-old patient with frequent monomorphic PVCs of epicardial origin, treated by radiofrequency ablation, followed by PFA. RESULTS After unsuccessful focus ablation through CVS with RFA, successful ablations from the same region with PFA were achieved. CONCLUSION This is the first described case of successful ablation of epicardial PVCs using PFA, which we hope will help in defining indications for this novel technology and enhance quality of treatment for patients with different arrhythmias.

Abstract
The coronary sinus Reducer (CSR) is an hourglass-shaped device which creates an artificial stenosis in the coronary sinus. Whilst placebo-controlled data show an improvement in angina, these results are unreplicated and are the subject of further confirmatory research. The mechanism of action of this unintuitive therapy is unknown. The Coronary Sinus Reducer Objective Impact on Symptoms, MRI Ischaemia, and Microvascular Resistance (ORBITA-COSMIC) trial is a randomised, placebo-controlled, double-blind trial investigating the efficacy of the CSR. Patients with (i) established epicardial coronary artery disease, (ii) angina on maximally tolerated antianginal medication, (iii) evidence of myocardial ischaemia and (iv) no further options for percutaneous coronary intervention or coronary artery bypass grafting will be enrolled. Upon enrolment, angina and quality-of-life questionnaires, treadmill exercise testing and quantitative stress perfusion cardiac magnetic resonance (CMR) imaging will be performed. Participants will record their symptoms daily on a smartphone application throughout the trial. After a 2-week symptom assessment phase, participants will be randomised in the cardiac catheterisation laboratory to CSR or a placebo procedure. After 6 months of blinded follow-up, all prerandomisation tests will be repeated. A prespecified subgroup will undergo invasive coronary physiology assessment at prerandomisation and follow-up. The primary outcome is stress myocardial blood flow on CMR. Secondary outcomes include angina frequency, quality of life and treadmill exercise time. (ClinicalTrials.gov: NCT04892537).

Abstract
In an adult patient, coronary artery fistula involving the circumflex artery (CX) connected to the coronary sinus caused aneurysm of the left main and CX associated with ectasia of the intermediate branch. The patient had posterolateral infarction with severe ischemic mitral regurgitation and moderate tricuspid regurgitation. A rare venous return anomaly was also present. The inferior vena cava, which was interrupted at the level of the liver, continued with the hemiazygos to drain into a persistent left superior vena cava, which in turn drained into the coronary sinus. Surgery included CX closure and mitral and tricuspid repair. The strategy had to be adapted to the anatomy. The fistula was dissected and snared for cardioplegia delivery, and venous return was achieved by cannulation of the superior vena cava and femoral vein. The procedure was uneventful, and 4 years later the patient is asymptomatic.

Abstract
Unroofed coronary sinus syndrome is a rare congenital cardiac anomaly, involving some anatomical variations. Approximately 60% of patients with unroofed coronary sinus syndrome have a concomitant atrial septal defect, which is termed unroofed coronary sinus atrial septal defect (CSASD). The precise detection of these abnormalities has been usually difficult with conventional echocardiography, mostly due to its small and complex structures. Herein, we report a case with unroofed coronary sinus atrial septal defect, in which preoperative contrast-enhanced computed tomography (CT) was useful in the operative decision making. We successfully repaired the defective roof of the coronary sinus with a bovine patch, while eliminating the inter-atrial shunt. The patient's postoperative course was uneventful with no residual shunt.

Abstract
BACKGROUND Posteroseptal accessory pathways (APs) associated with coronary sinus (CS) diverticulum present a rare and challenge for ablation. This study aimed to compare the safety and efficacy of conventional approach and three-dimensional (3D) mapping system in the catheter ablation. METHODS AND RESULTS This was a retrospective study of all patients (from January 2013 to July 2022) who underwent catheter ablation of posteroseptal AP associated with CS diverticula in our center. Patients who underwent catheter ablation using the traditional fluoroscopy method were included in the conventional method group (n = 13). Patients who underwent catheter ablation using the 3D mapping method were included in the 3D mapping group (n = 11). Clinical characteristics, ablation procedure, and outcomes were recorded and analyzed between the two groups. Out of 669 patients with posteroseptal APs, 24 of them (3.6%) were associated with CS diverticula. All patients in both groups successfully completed the electrophysiological study. In the conventional method group, two patients experienced complications (one patient with pericardial effusion and the other patient with femoral arterial hematoma), and two patients had recurrence. However, no patients suffered from complications or recurrence during follow-up. The procedure time and fluoroscopy time in the conventional method group were significantly longer than those in the 3D mapping method group. CONCLUSIONS The utilization of 3D mapping led to reduced fluoroscopy time, shorter procedure duration, enhanced acute success rates, and decreased incidence of complications.

Abstract
Coronary sinus Reducer implantation is a percutaneous technique used to treat patients suffering from refractory angina pectoris. The device narrows the coronary sinus, increases the back pressure in the myocardial venous system and forces redistribution of coronary blood flow from less ischemic subepicardium to the more ischemic subendocardium. Multiple clinical studies had proven its efficacy to alleviate myocardial ischemia and related symptoms, and to improve the quality of life of patients with refractory symptomatic chronic coronary artery disease for whom coronary revascularization is deemed unsuitable. This literature review aims to expose the device design, its mechanisms of action, and the clinical data supporting its use. Since November 2021 Reducer's reimbursement has been granted in France by the national health authority. It is the first device to be approved under a newly established reimbursement approval process. A transitional coverage is provided with opportunities for renewal before applying for full-time reimbursement. To fulfill the requirements of the National Commission for Evaluation of Medical Devices and Health Technologies, the French Society of Cardiology has been creating the France Reducer registry. This clinical registry has been collecting data from patients undergoing coronary sinus Reducer implantation regarding their clinical situation, periprocedural information, and one-year follow-up. It is crucial for the future of this emerging therapeutic option in France. To date, 215 patients from 28 centers have been included between June 2022 and September 2023.

Abstract
BACKGROUND Intracoronary sinus ablations have been performed for various arrhythmical substrates. The aim of this study is to report our experience on pediatric patients of the safety and efficacy of ablations in the coronary sinus. METHODS This is a retrospective study of all patients who underwent ablations in the coronary sinus from October 2013 to October 2021 at a single center. Clinical presentation, type of arrhythmia causing tachycardia, ablation procedure, and outcome were recorded. RESULTS A total of 27 patients were included in the study. Nineteen (69%) of those followed up received a diagnosis of Wolff-Parkinson-White syndrome (WPW), 4 (15%) were cases of supraventricular tachycardia with concealed accessory pathway (AP), 2 (8%) were cases of focal atrial tachycardia, and 2 (8%) were cases of permanent junctional reciprocating tachycardia. Negative delta wave was noteworthy especially in lead II in 11/19 (58%) cases and coronary sinus diverticulum was detected in the WPW cases. Of those with manifest AP (19 cases), 15 (79%) had a high-risk AP and the AP in all WPW cases was adenosine unresponsive. Radiofrequency (RF) catheter ablation was performed in 25/27 (93%) cases during the procedure, and 16/25 (64%) of these were irrigated RF catheters. No complications were observed in the follow-up, including coronary artery injury. CONCLUSIONS Catheter ablation of supraventricular tachyarrhythmias can be accomplished effectively and potentially safely within the coronary sinus. Coronary sinus diverticula should be suspected in patients with manifest posteroseptal APs who have a previous failed ablation and typical electrocardiographic signs.

Abstract
INTRODUCTION Herein, we present a rare case of the successful ablation of an accessory pathway (AP) involving the Marshall Bundle (MB) and coronary sinus musculature (CSM) in a 40-year-old man with Wolff-Parkinson-White syndrome. METHODS AND RESULTS An orthodromic reciprocating tachycardia (ORT) was inducible with the earliest atrial activation site located at the posterolateral mitral annulus. The local conduction and the cycle length of ORT was prolonged by peri-mitral ablation; however, it failed to block the AP. The atrial insertion of the AP was identified by remapping during ORT at the left atrial ridge, which was away from the mitral annulus, where ablation was successful. Together with the electrophysiological findings in CSM potentials, we conclude that the epicardial MB-CSM connection functioned as the AP in this patient. CONCLUSION The novel variant form of AP comprised of MB and CSM should be noted. The atrial insertion of the MB may be the target of catheter ablation.

Abstract
Wolff-Parkinson-White syndrome is a congenital cardiac pre-excitation syndrome that is effectively treated by ablating the accessory pathway. However, accessory pathways located in the posteroseptal region can sometimes be challenging. In this paper, we present the successful ablation of the epicardial posteroseptal accessory pathway through the middle cardiac vein in a 13-year-old girl with a coronary sinus diverticulum and Wolff-Parkinson-White syndrome, after unsuccessful ablation attempts at different locations. If the ablation procedure fails, the possibility of the posteroseptal pathway should be kept in mind, and coronary sinus angiography should be performed. In cases with a coronary sinus diverticulum where ablation is not successful, other coronary sinus structures, for example, the middle cardiac vein should be considered as potential accessory pathways.

Abstract
BACKGROUND The vein of Marshall (VOM) ethanol infusion is increasingly performed in combination with catheter ablation in atrial fibrillation (AF). The cannulation of the VOM can sometimes be challenging. This study aimed to evaluate the double-wire technique in cases of difficult cannulation of the VOM. CASE PRESENTATION Patients with AF scheduled for combined catheter ablation and VOM ethanol infusion were consecutively enrolled. The procedure was performed via the femoral vein. If the regular cannulation technique with one angioplasty wire failed or took more than 20 min, the double-wire technique using a stabilizing wire and a cannulation wire was performed. The unique technique was used mainly in two scenarios, when the Eustachian ridge was too prominent as a barrier for catheter manipulation or when the VOM ostium was close to the coronary sinus ostium. Of 162 patients scheduled for VOM ethanol infusion, the double-wire technique was applied in 6 (3.7%) patients and led to a 100% successful cannulation rate of the VOM. Of the six patients, two had a prominent Eustachian ridge, and four had a VOM ostium close to the coronary sinus ostium. The mean cannulation time was 33.3 ± 7.3 min. The ethanol infusion was successfully performed in 5 patients. One patient had a collateral circulation in the distal VOM, and ethanol infusion was not performed. CONCLUSIONS The double-wire technique can facilitate VOM cannulation and ethanol infusion in challenging cases. WORD COUNT 231.

Abstract
Coronary sinus narrowing device (reducer) implantation has emerged as an effective treatment to improve the quality of life and functional capacity in patients suffering from disabling refractory angina. Left ventricle global longitudinal strain (LV-GLS) is a useful tool for early diagnosis of subclinical cardiac injury and an independent predictor for coronary artery disease. We aimed to investigate whether LV-GLS could help predict clinical improvement after coronary sinus reducer implantation. LV-GLS assessments were performed at baseline and 6 months after reducer implantation in consecutive patients treated for refractory angina. Patients were divided into 2 groups based on reduced (<17% absolute value) or preserved baseline LV-GLS. Clinical improvement was defined as an increase of ≥25 m in the 6-minute walk test (6MWT) at follow-up. Overall, 41 patients were included, 31 in the reduced LV-GLS group and 10 in the preserved LV-GLS group. The mean age was 68 ± 8 years, with only 2 female patients (5%). Baseline characteristics did not differ significantly between the 2 groups. Univariable analysis revealed that LV-GLS was the only significant predictor for 6MWT improvement. Baseline preserved LV-GLS reduced the likelihood of 6MWT improvement by 82% (odds ratio 0.18 [0.04 to 0.83], p = 0.029). A significant increase in 6MWT (307 ± 97 m to 343 ± 92 m, p = 0.017) was observed in the reduced LV-GLS group, compared with a decrease in the preserved LV-GLS group (378 ± 86 m to 361 ± 123 m, p = 0.651). In conclusion, reduced LV-GLS may serve as a marker for potential clinical improvement in patients with refractory angina treated with reducer. Larger clinical trials are needed to establish its role.

Abstract
Aberrant origin of coronary artery is a rare congenital anomaly associated with increased risk of myocardial ischemia and sudden death, with the highest risk lesions being those arising from the opposite sinus of Valsalva. We report a case with an aberrant right coronary artery arising superior to the left coronary cusp, with a slit-like ostium, having an inter-arterial and intramural course through the aortic root, that underwent repositioning of the right coronary artery. We believe such cases warrant surgical correction and reimplantation is a safe, effective and reproducible technique.

Abstract
INTRODUCTION In this study, we present a case of directing persistent left superior vena cava drainage into the unroofed coronary sinus to the right atrium in a patient with tetralogy of Fallot and coronary sinus orifice atresia without innominate vein. CASE REPORT A 16-month-old boy diagnosed with tetralogy of Fallot was admitted. Following intracardiac repair, the left superior vena cava was divided from the left atrial junction, passed through under the ascending aorta and anastomosed to the right superior vena cava. CONCLUSION To our knowledge, this is the first patient reported with persistent left superior vena cava, unroofed coronary sinus, coronary sinus orifice atresia, and tetralogy of Fallot. The extracardiac direct anastomosis technique was used successfully to direct persistent left superior vena cava to the right atrium without any post-procedure complications.

Abstract
INTRODUCTION Previous studies demonstrated that the coronary sinus (CS) is an important target for ablation in persistent atrial fibrillation. However, radiofrequency ablation in the CS is associated with coronary vessel damage and tamponade. Animal data suggest irreversible electroporation (IRE) ablation can be a safe ablation modality in vicinity of coronary arteries. We investigated the feasibility of IRE in the CS in a porcine model. METHODS Ablation and pacing was performed in the CS in six pigs (weight 60-75 kg) using a modified 9-French steerable linear hexapolar Tip-Versatile Ablation Catheter. Pacing maneuvers were performed from distal to proximal segments of the CS to assess atrial capture thresholds before and after IRE application. IRE ablations were performed with 100 J IRE pulses. After 3-week survival animals were euthanized and histological sections from the CS were analyzed. RESULTS A total of 27 IRE applications in six animals were performed. Mean peak voltage was 1509 ± 36 V, with a mean peak current of 22.9 ± 1.0 A. No complications occurred during procedure and 3-week survival. At 30 min post ablation 100% isolation was achieved in all animals. At 3 weeks follow-up pacing thresholds were significant higher as compared to baseline. Histological analysis showed transmural ablation lesions in muscular sleeves surrounding the CS. CONCLUSION IRE ablation of the musculature along the CS using a multi-electrode catheter is feasible in a porcine model.

Abstract
Coronary sinus reducer migration during implantation is an unusual complication with no standard bailout strategy and to the best of our knowledge there is no description of migration to the pulmonary artery. A mother-and-child technique during implantation could be the safest way to avoid this complication.

Abstract
BACKGROUND Literature reports 5% of recurrence/failure in paediatric accessory pathway ablations. Our aim was to investigate the reasons underlying this finding and share techniques to obtain long-term success. METHODS Thirty-nine paediatric patients referred for a repeat procedure were analysed: characteristics of the pathways and the initial and redo procedures were identified. RESULTS Mean age was 11.9 ± 3.3 years (59% males). Three patients (8%) had multiple accessory pathways. The most frequent location was left lateral (26%). Left sided pathway recurrence was caused mainly by poor contact (60%) and inadequate mapping (40%). For right lateral accessory pathways, poor contact accounted for 70% of failures. For antero-septal and para-Hisian locations, the use of cryoablation and choice of low radiofrequency energy delivery accounted for > 75% of failures. Long-term success strategies included choice of contact force catheters and radiofrequency applications at the ventricular insertion of the pathway and in the aortic coronary cusps. In postero-septal substrates, the main reason accounting for failure was deep or epicardial location of the pathway (37%), solved by using an irrigated tip catheter or applying lesions within the coronary sinus, or applications from both right and left postero-septal areas. CONCLUSION Acute failure and post-procedure recurrence in paediatric accessory pathway ablations have multiple reasons related to the characteristics of the pathway and the technology available. Accurate understanding of the anatomy, careful mapping and pacing manoeuvers, and incorporation of new technologies contribute to achieve a definitive success in > 98% of procedures.

Abstract
Persistence of the left superior vena cava is often an incidental finding during cardiac surgical procedures. In minimally invasive valvular surgery, it may jeopardise venous drainage and myocardial protection. This How-To-Do-It paper describes the cannulation strategy in a case of minimally invasive mitral surgery in a patient with persistence of the left superior vena cava and absence of the anonymous vein detected with preoperative multimodality imaging.

Abstract
Refractory angina affects an increasing proportion of the population with advanced coronary artery disease and microvascular dysfunction. Limited effective pharmacological and interventional therapies exist for this patient cohort. The coronary sinus (CS) reducer, recently recommended in the 2019 guidelines of the European Society of Cardiology for the management of chronic refractory angina, is a balloon-expandable, stainless-steel device designed for implantation in the CS. It acts by increasing CS pressure, thereby redistributing blood to ischemic myocardium, relieving symptoms, and improving quality of life. However, between 15%-30% of patients do not respond to this treatment. Six mechanisms appear to explain this poor response to CS reducer therapy: (1) inappropriate patient selection; (2) cardiac venous system heterogeneity; (3) CS size; (4) incomplete device endothelialization; (5) coronary artery disease phenotype and progression; and (6) limited myocardial ischemia at baseline. We hereby review these mechanisms in detail and highlight key areas that should be addressed in order to try and reduce the burden of non-responders following CS reducer implantation.

Abstract
Coronary sinus aneurysm is a rare heart anomaly. Herein, we report a rare case with giant coronary sinus aneurysm misdiagnosed as an extracardiac mediastinal tumor. The preoperative diagnostic imaging failed to diagnose the correct location of the tumor and a simple resection was planned. It turned out to be coronary sinus aneurysm intraoperatively and required cardiopulmonary bypass support for the resection.

Abstract
A 58-year-old woman was referred to our hospital with progressively increasing breathlessness. She reported a history of bioprosthetic valve implantation for tricuspid valve replacement and direct closure of an atrial septal defect for Ebstein's anomaly, 31 years before presentation. Transthoracic echocardiography revealed prosthetic valve failure, an enlarged coronary sinus, and severe mitral regurgitation. Computed tomography revealed a giant coronary sinus with thrombosis and persistent left superior vena cava. She underwent successful mitral and tricuspid valve replacement; however, severe hemodynamic deterioration necessitated mechanical ventilatory support with extracorporeal membrane oxygenation.

Abstract
Objective This study was performed to identify the effects of different surgical approaches on the right coronary artery ostium in patients with congenital supravalvular aortic stenosis (SVAS) and to determine how to avoid surgically induced right coronary artery occlusion. Methods The surgical techniques and outcomes of 91 patients who underwent surgical treatment of SVAS from 2008 to 2015 in our institution were retrospectively reviewed to identify the causes of early death, reoperation, and extracorporeal membrane oxygenation (ECMO) support. Results Four perioperative deaths (Doty’s technique, n = 4), six cases of ECMO support (Doty’s technique, n = 4; Brom’s technique, n = 1; McGoon’s technique, n = 1), and eight reoperations (Doty’s technique, n = 5; Brom’s technique, n = 2; McGoon’s technique, n = 1) occurred. In cases of reoperation, adjustment of the shape and position of the right coronary sinus patch relieved the malignant arrhythmia. Conclusion Different surgical techniques have different effects on the right coronary artery. The shape of the patch inserted into the right coronary sinus should be carefully clipped to avoid distortion and ischemia of the right coronary artery.

Abstract
PURPOSE OF REVIEW Refractory angina (RA), which is characterized by tissue ischemia along with neurological, mitochondrial, and psychogenic dysfunction, is becoming a major cause of morbidity in patients with advanced coronary artery disease. In this review, we discuss in detail the invasive mechanical non-cell therapy-based options, the evidence behind these therapies, and future trends. RECENT FINDINGS There is extensive ongoing research in the areas of spinal-cord stimulation, transmyocardial laser revascularization, sympathectomy, angiogenesis, and other non-cell-based therapies to explore the best therapy for refractory angina. There is conflicting data in the literature suggesting subjective improvement in angina, but very few studies boast improvement in core objective parameters such as myocardial blood flow, survival, or rehospitalizations. Patients with refractory angina are a complex group of patients that need novel approaches to help alleviate their symptoms and reduce mortality. A carefully selected sequence of therapies may provide the best results in this patient population.

Abstract
Cardiac resynchronization therapy (CRT) has become the gold standard for patients with systolic left ventricular function, left ventricular ejection fraction less than or equal to 35%, wide complex QRS, and symptomatic heart failure. Annual implantation volume has steadily increased because of expanding indications for CRT. Improved survival resulted in many of these patients having their CRT devices for many years and eventually requiring an increased number of device-related procedures, including coronary sinus lead revisions and replacements following a coronary sinus lead extraction.

We report a case of coronary sinus (CS) injury with a retrograde cardioplegia catheter and repair that compromised CS patency. This resulted in acute global cardiac dysfunction shortly after weaning from bypass, which reversed after patch repair with confirmed CS patency. The case report shows that acute CS occlusion may not be tolerated in some humans.

Unroofed Coronary Sinus Syndrome: An Easily Corrected Congenital Anomaly But More Diagnostic Suspicion Is Needed. Heart Lung Circ 2017; 27:731-738.

Abstract
BACKGROUND Unroofed coronary sinus syndrome (URCSS) is a spectrum of cardiac anomalies in which part (partial type) or the entire common wall (complete type) between the coronary sinus (CS) and left atrium is absent. It is commonly associated with a persistent left superior vena cava (PLSVC). The PLSVC can even anomalously connect to the left atrium in complete type anomaly. URCSS has been reported to be associated with delayed diagnosis and life-threatening cerebral injury. The purpose of the present study was to review our experience with surgical correction of this often-concealed malformation and discuss methods for reducing diagnostic omission. METHODS Thirty-six patients with URCSS who underwent surgical treatment from 1998 to 2015 in our institution were enrolled in this retrospective analysis. RESULTS The mean age of the patients was 21.8±20.9 years. Type I anomalies were found in 15 (41.7%) patients, type II in 4 (11.1%), type III in 6 (16.7%), and type IV in 11 (30.6%). A patient presenting with URCSS without other defects was identified in six (16.7%). One patient (2.8%) had a history of paradoxical embolisation. Twenty-five patients (69.4%) were diagnosed before surgery. Ten patients (27.8%) were diagnosed with URCSS intraoperatively. One patient (2.8%) was diagnosed with URCSS by follow-up echocardiography after device occlusion for atrial septal defect. Coronary sinus ostium dilation was the most important clue leading to partial type lesion disclosure intraoperatively. The anomalous PLSVC of 15 patients was repaired using roof tunnel technique in four (26.7%) cases, baffle redirection in eight (53.3%) cases, posterior left atrial wall plicating in two (13.3%) cases, and extracardiac bypass in one (6.7%) case. Postoperative complete atrioventricular block occurred in one patient (2.8%). One patient died postoperatively (2.8%). All patients are doing well after discharge from hospital. CONCLUSIONS Diagnostic suspicion can contribute to lesion disclosure. Surgical correction has good long-term outcomes and low risks.

Abstract
Objectives: To determine the correlation exists between ventricular septal defect (VSD) and ruptured sinus of Valsalva aneurysm (RSVA). Methods: Between September 2003 and April 2014, 80 RSVA patients underwent surgical repair. These patients were retrospectively divided into two groups: the VSD group (38 cases) and the non-VSD group (42 cases). Results: Rupture points of SVA originated more frequently in the right coronary sinus (RCS) of patients in the VSD group than those in the non-VSD group (p=0.002). In the VSD group, more than 92.1% tended to rupture into the right ventricular outflow tract. The rupture points are diverse in the non-VSD group. A significant difference was found in rupture points of RSVA between the two groups (p<0.001). Patients in the VSD group presented with aortic valve disease more often than those in the non-VSD group (p<0.001). A total of 67 patients were repaired with a patch at the opening of RSVA; of those, all patients in VSD group and 29 patients in non-VSD group were repaired with a patch. Nine patients in non-VSD group received transcatheter closure of RSVA. Conclusion: The presence or absence of VSD affects the rupture points of SVA, aortic valve disease involved, and therapeutic schedule. Ruptured sinus of Valsalva aneurysm type should be clinically modified on the basis of presence or absence of VSD.

Abstract
An alternative to coronary sinus implantation for a left ventricular pacing lead is frequently needed for cardiac resynchronization therapy. We have developed a transapical approach to implant an endocardial pacing lead that will reach the most delayed segment of the left ventricle. This method is easily combined with other transapical heart surgeries. After some technological improvement our technique should offer easier access and better results than other currently available implantation methods.

Abstract
We report a contained rupture of a right coronary sinus of Valsalva aneurysm, in which repair resulted in symptomatic improvement. Patients often present with symptoms secondary to rupture of the sinus of Valsalva aneurysm into one of the cardiac chambers, or secondary to the compression of adjacent structures. Whereas sinus of Valsalva aneurysms and their rupture are well reported in the literature, contained ruptures have been described only rarely. In those cases, symptoms often arose from compression of adjacent structures. Although transesophageal echocardiography is considered to be the diagnostic method of choice, cardiac magnetic resonance imaging and computed tomography can be equally helpful in establishing the diagnosis and delineating the lesion. Diagnosis and prompt repair in our 64-year-old patient resulted in the rapid resolution of his symptoms.

Abstract
We report a rare causal association between obstructed supracardiac totally anomalous pulmonary venous drainage and coronary sinus ostial atresia. Our 12-week-old patient developed venous myocardial infarction secondary to coronary venous hypertension because her sole route of coronary venous drainage was obstructed. She recovered after the obstruction was relieved by balloon dilation. Surgical repair then included anastomosis of the pulmonary venous confluence to the left atrium, ligation of the vertical vein, and unroofing of the coronary sinus. Coronary sinus ostial atresia is rarely diagnosed before autopsy.

Abstract
Background Implantation of coronary sinus (CS) leads may be a difficult procedure due to different vein anatomies and a possible lead dislodgement. The mode of CS lead fixation has changed and developed in recent years. Objectives We compared the removal procedures of active and passive fixation leads. Methods Between January 2009 and January 2014, 22 patients at our centre underwent CS lead removal, 6 active and 16 passive fixation leads were attempted using simple traction or lead locking devices with or without laser extraction sheaths. Data on procedural variables and success rates were collected and retrospectively analyzed. Results The mean patient age was 67.2 ± 9.8 years, and 90.9% were male. The indication for lead removal was infection in all cases. All active fixation leads were Medtronic® Attain StarFix™ Model 4195 (Medtronic Inc., Minneapolis, MN, USA). The mean time from implantation for the active and passive fixation leads was 9.9 ± 11.7 months (range 1.0–30.1) and 48.7 ± 33.6 months (range 5.7–106.4), respectively (p = 0.012). Only 3 of 6 StarFix leads were successfully removed (50%) compared to 16 of 16 (100%) of the passive fixation CS leads (p = 0.013). No death or complications occurred during the 30-day follow-up. Conclusion According to our experience, removal of the Starfix active fixation CS leads had a higher procedural failure rate compared to passive.

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.

Abstract
Unroofed coronary sinus( UCS) is a rare cardiac anomaly and the most uncommon type of atrial septal defect. It is rarely diagnosed by only echocardiography prior to surgery. We herein report a case of UCS (partially unroofed terminal portion) without persistent left superior vena cava that was precisely diagnosed by cardiac multi-detector low computed tomography (MDCT). A 50-year-old asymptomatic man was admitted for cardiac evaluation. A transesophageal echocardiography showed a left to right shunt at the atrial level. MDCT clearly showed a defect in the coronary sinus and lower part of the interatrial septum. At the time of surgery, the defect was closed using a Gore-Tex patch, such that the coronary sinus drained entirely into the left atrium. The postoperative course was uneventful. Cardiac MDCT provides accurate anatomic details about defects as well as the associated anomalies of the heart and pulmonary vasculature.
