NCT ID: NCT06261788 Completed - Valve Heart Disease Clinical Trials

Efficacy and Safety of the Sync-AV II Temporary Cardiac Pacing Catheter

Start date: June 1, 2023
Phase: N/A
Study type: Interventional

This is a prospective, single-center, non-randomized open label study. The objective of this study is to evaluate the efficacy and safety of the Sync-AV II Temporary Cardiac Pacing Catheter in subjects whose elective surgical or interventional procedure require temporary pacing support.

NCT ID: NCT06119009 Completed - Heart Block Clinical Trials

New-onset Heart Blocks After Noncardiac Surgery: a Retrospective Study of More Than 280,000 Patients

Start date: January 1, 2008
Phase:
Study type: Observational

This study aimed to investigate new-onset heart blocks after noncardiac surgery, identify risk factors, and develop a prediction model.

NCT ID: NCT04931693 Completed - Clinical trials for Complete Heart Block

PECs Block for Pacemaker Insertion in Children

Start date: December 20, 2021
Phase: Phase 4
Study type: Interventional

Evaluation of Ultrasound Guided Modified Pectoral Nerves Blocks in Transvenous Subpectoral pacemaker insertion in Children: Randomized Controlled Trial

NCT ID: NCT04632641 Completed - Atrial Fibrillation Clinical Trials

Suture Closure AFtEr VEIN Access for Cardiac Procedures (SAFE-VEIN) Trial

SAFE-VEIN
Start date: April 23, 2021
Phase: N/A
Study type: Interventional

Primary objective: To compare the safety and efficacy of closure strategies post venous access procedures. Hypothesis: We anticipate that the use of a venous closure device will decrease the time to hemostasis (TTH), time to ambulation (TTA) and time to discharge (TTD) compared to conventional methods of closure following venous access procedure.

NCT ID: NCT04537455 Completed - Clinical trials for Left Bundle-Branch Block

Non-invasive Mapping Using Ultra-high Frequency Electrocardiography

Start date: October 1, 2019
Phase: N/A
Study type: Interventional

Cardiac electrical mapping is an important tool that allows doctors to study the electrical activity of the heart in detail. Electrical mapping systems used in clinical practice are time consuming, invasive and very costly. Ultra-high frequency electrocardiography is a novel non-invasive cardiac mapping system. Ultra-high frequency electrocardiography (UHF-ECG) can be performed in 10-15 minutes without any risk or discomfort to patients. The aim of this study is to refine this mapping system, verify it against invasive mapping and develop software to bring this novel system into routine clinical use including predicting which patients will respond to cardiac resynchronisation therapy.

NCT ID: NCT04489095 Completed - Aortic Stenosis Clinical Trials

Conduction Disease After Transcatheter Aortic Valve Replacement

Start date: July 16, 2020
Phase: N/A
Study type: Interventional

This is a prospective single center Cardiology department observational study. The study aim is to better understand the predictors of high grade conduction abnormalities associated with TAVR such that a more robust evidence-based and universal strategy to manage cardiac conduction disturbances in these patients, which has been elusive, can be developed.

NCT ID: NCT04245345 Completed - AV Block Clinical Trials

Accelerometer Sensing for Micra AV Study

AccelAV
Start date: June 9, 2020
Phase: N/A
Study type: Interventional

The purpose of the AccelAV Study is to characterize chronic AV synchrony in subjects implanted with MicraTM AV device. This study will be conducted upon market approval of the MicraTM AV Transcatheter Pacing System.

NCT ID: NCT04221763 Completed - Heart Failure Clinical Trials

Mechanisms and Innovations in Cardiac Resynchronisation Therapy

MIC
Start date: October 15, 2019
Phase: N/A
Study type: Interventional

The aim of this study is to compare the effectiveness of multiple modalities of cardiac resynchronisation therapy using high precision acute electrical and haemodynamic measurements.These modalities include biventricular pacing and conduction system pacing utilising His bundle and left bundle pacing. Conduction system pacing is a more physiological form of pacing. The study hypothesises that this will produce more effective cardiac resynchronisation.

NCT ID: NCT03803995 Completed - Heart Failure Clinical Trials

Mapping and Pacing of the His Bundle for Heart Failure Patients With Left Bundle Branch Block

MAP HIS HF
Start date: March 20, 2019
Phase: N/A
Study type: Interventional

This is a prospective, single-arm, non-randomized, non-blinded study designed to characterize the locations of His Bundle (HB) pacing that results in correction of electrical dyssynchrony and to characterize morphology and activation time of local intracardiac electrogram (IEGM) with an electro-anatomical mapping system during a device implant procedure and secondarily to assess the efficacy of HB pacing or HB plus LV pacing (when indicated) in correction of electrical dyssynchrony in heart failure patients with left bundle branch block.

NCT ID: NCT03719040 Completed - Heart Failure Clinical Trials

Physiologic Pacing Registry

Start date: November 27, 2018
Phase:
Study type: Observational [Patient Registry]

The Physiologic Pacing Registry is a prospective, observational, multi-center registry performed to gain a broader understanding of 1) physiologic pacing implant and follow-up workflows, including pacing and sensing measurements and 2) the clinical utility in creating a 3-dimensional electro-anatomical map of cardiac structures prior to physiologic pacing device implants based on the clinical site's routine care.
