Development and Validation of the Kansas City Cardiac Dysautonomia Questionnaire (KCDysQ)

Main aim will be to compare in patients with cardiac dysautonomia, newly developed disease specific questionnaire to established generalized SF-36 and EQ-5d questionnaires, as there are no disease specific questionnaires for comparison. These novel and established questionnaires will then be compared among groups who have relatively stable disease or stable symptoms with patients who will be expected to have a change in symptoms and QoL.

Use of 4D-ICE in Conjunction With TEE for Left Atrial Appendage Closure

This is a prospective, single center, non-randomized study with two parallel arms intended to study if 4D Intracardiac echocardiography (4D-ICE) (Nuvision, Nuvera TM) will provide better visualization of the anatomical landmarks from the larger imaging volume and provide optimal intra procedural guidance similar to Transesophageal echocardiography (TEE) (GE 6VT-D ULTRASOUND TRANSDUCER) for Left atrial appendage closure (LAAC). The study will enroll approximately 52 subjects and will be followed through 12 months.

Effectiveness of Bupivacaine, Ketorolac, Ketamine, vs Bupivacaine Alone in Reducing Postoperative Pocket Pain

Bupivacaine is the most widely used local anesthetic agent across majority of the Cardiac Implantable Electronic device (CIED) implant procedures in the United States. It is hypothesized that the combination of Bupivacaine-Ketorolac-Ketamine (BKK) is more effective in alleviating perioperative and postoperative pain as compared to the use of bupivacaine alone. A few studies have been done to look for the effectiveness of BKK in abdominal surgical procedures. However, no study has been done to evaluate its efficacy and effectiveness in patients undergoing CIED insertion.

Impact of Steerable Delivery Sheaths on Successful Closure of LA A With AMULET

The novel Amplatzer steerable delivery sheath (Abbott Vascular) is found to be safe and effective in performing LAAO procedure. However, the procedural outcomes have not been compared with the traditional non-steerable fixed curve sheath. In this study investigators aim to compare the outcome of patients undergoing left atrial appendage occlusion with the dual mechanism closure Amulet device using non-steerable fixed curve sheath versus a novel steerable sheath.

Long Term Evaluation of Cardiac Arrhythmias After Transcatheter Aortic Valve Implantation -The LOCATE Registry

The purpose of the Long term Evaluation of Cardiac Arrhythmias after Transcatheter Aortic Valve Implantation (LOCATE) Registry is to perform long-term ambulatory monitoring of patients with severe aortic stenosis who undergo trans-catheter aortic valve implantation (TAVI) and develop new onset conduction system abnormalities post-procedure that do not require urgent permanent pacemaker (PPM) implantation. The primary objectives of this study are to assess the incidence of late onset heart block necessitating PPM implantation and to evaluate the incidence of new onset atrial fibrillation (AF) following TAVI. This study aims to provide valuable insights into the long-term cardiac health of TAVI patients and inform the development of improved treatment strategies for aortic stenosis patients with conduction system abnormalities.

Observational Study to Examine the Procedural and Outcomes of AF Ablation Assisted by STAR Apollo™ Mapping System

STAR Apollo Mapping System is an FDA cleared mapping technology that can analyze the signals collected during the ablation procedure on the 3D mapping system and give the physician further insight into the AF activation patterns which may assist them in identifying areas responsible for maintaining Atrial Fibrillation (AF). The STAR Apollo Mapping System system allows clinicians, after treating the Pulmonary Veins (PV), to collect data from the atria during clinical AF procedures using standard FDA cleared catheters and devices. This study aims to examine the impact of the STAR Apollo Mapping System on procedural and acute outcomes in a multicenter observational study.
