Background: Cavo-tricuspid isthmus (CTI) dependent atrial flutter is typically treated with cardiac ablation. Standard techniques to assess CTI block after ablation can be technically challenging. Right ventricular (RV) pacing may allow for another technique to assess CTI block after ablation. Objective: The purpose of this study was to evaluate RV pacing as a method to assess CTI block after ablation of CTI dependent atrial flutter, and define endpoints of ablation using this technique. Methods: 28 patients undergoing ablation of CTI dependent atrial flutter with intact ventriculoatrial (VA) conduction were prospectively enrolled in this study and underwent the RV pacing protocol, as well as standard coronary sinus (CS) pacing techniques to assess CTI block...

Oxidative stress has been considered to be an important factor contributing to postoperative atrial fibrillation (PoAF). Mitochondrial DNA (mtDNA) copy number in peripheral blood has been found to be associated with a patient's oxidative stress. Therefore, we sought to determine whether there was association between mtDNA copy number and the onset of atrial fibrillation. mtDNA copy numbers were measured using the quantitative real-time polymerase chain reaction in peripheral blood from 485 consecutive patients with sinus rhythm undergoing coronary artery bypass grafting...

REVIEW
Advay G Bhatt, Jonathan S Steinberg
Robot-assisted left ventricular lead implantation for cardiac resynchronization therapy is a feasible and safe technique with superior visualization, dexterity, and precision to target the optimal pacing site. The technique has been associated with clinical response and beneficial reverse remodeling comparable with the conventional approach via the coronary sinus. The lack of clinical superiority and a residual high nonresponder rate suggest that the appropriate clinical role for the technique remains as rescue therapy...

Although cardiac resynchronization therapy improves morbidity and mortality in patients with cardiomyopathy, heart failure, and electrical dyssynchrony, the rate of nonresponders using standard indications and implant techniques is still high. Optimal coronary sinus lead positioning is important to increase the chance of successful resynchronization. Patient factors such as cause of heart failure, type of dyssynchrony, scar burden, coronary sinus anatomy, and phrenic nerve capture may affect the efficacy of the therapy...

Cardiac resynchronization therapy (CRT) improves left ventricular function, especially in patients with left bundle branch block or those receiving chronic right ventricular pacing. CRT is typically accomplished by placing a right ventricular endocardial pacing lead and a left ventricular pacing lead via the coronary sinus to a coronary vein overlying the lateral or posterolateral left ventricle. CRT can be combined with an implantable defibrillator or with a pacemaker. Limited data are available to compare these two versions of CRT head to head...

REVIEW
Edmond M Cronin, Bruce L Wilkoff
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...

The patient was an-85-year-old man with hypertension and hyperlipidemia. The patient had a history of faintness on standing. He visited our hospital after experiencing chest oppression and pre-syncope in 2015. Brain magnetic resonance imaging and echocardiography did not detect any structural brain or heart disease. Ischemic heart disease was suspected based on the myocardial scintigraphy findings, but coronary angiography revealed no unusual findings. Holter electrocardiography did not reveal the reason for his symptoms...

Aneurysms of the sinus of Valsalva are very uncommon, with an incidence ranging from 0.1 to 3.5% of all congenital heart defects. Very few cases have been reported in the literature that presented with involvement of two or more sinuses. We report a case of 27-year-old male with a history of exertional breathlessness of one-month duration. After complete evaluation using transesophageal echocardiography (TEE) and multiple detector computed tomography (MDCT) scanning, the patient was diagnosed to have large congenital unruptured sinus of Valsalva aneurysms involving both left and right coronary sinuses with extension into the interventricular septum...

Refractory angina (RFA) is an unfavourable condition that is characterized with persistent angina due to reversible myocardial ischaemia in patients with coronary artery disease that remains uncontrollable despite an optimal combination of pharmacological agents and revascularization. Despite significant advances in revascularization techniques and agents used in pharmacological therapy, there is a significant population suffering from RFA and the global prevalence is even increasing. Anti- anginal treatment and secondary risk-factor modification are the traditional approaches for this group of patients...

The new percutaneous Impella CP (Cardiac Power; Abiomed, Inc., Danvers, MA) was designed to provide a higher level of support than Impella 2.5 (Abiomed, Inc.). We present the first documented case of a patient that was transitioned from the Impella 2.5 to Impella CP. A 48-year-old male patient with no medical history was transferred to our institution with a one day history of worsening shortness of breath. The patient was unstable and found to have monomorphic ventricular tachycardia at 220 beats/min that was cardioverted to normal sinus rhythm...

INTRODUCTION: Cardiac resynchronization therapy (CRT) device implantation guided by an electroanatomic mapping system (EAMS) is an emerging technique that may reduce fluoroscopy and angiography use and provide information on coronary sinus (CS) electrical activation. We evaluated the outcome of the EAMS-guided CRT implantation technique in a multicenter registry. METHODS: During the period 2011-2014 we enrolled 125 patients (80% males, age 74 [71-77] years) who underwent CRT implantation by using the EnSite NavX system to create geometric models of the patient's cardiac chambers, build activation mapping of the CS and guide leads positioning...
