Ventricular Tachycardia

Ventricular Tachycardia (VT) is a life threatening heart rhythm that comes from the bottom chambers of the heart (the ventricles) and is a leading cause of sudden cardiac death. The majority of patients that are at risk of VT or suffer a cardiac arrest will have an Internal Cardiac Defibrillator (ICD) in situ to treat the abnormal heart rhythm. The ICD can deliver a painful shock to restore normal heart rhythm but importantly does not treat the underlying cause. Current treatment for the prevention of recurrent VT include catheter ablation (CA) or medication. Long-term results with global 12 month VT-free survival rates with CA are around 50%. The trial is to compare 2 different types of ablation catheter that are used to cauterise small areas of unhealthy tissue within the heart that are responsible for VT: Diamond Temp (DT) and Tacticath/Tactiflex (TF). Our hypothesis is that the DT ablation catheter will provide comparable efficacy and safety for the treatment of VT as the current industry gold standard (TF).

Ivabradine for Long-Term Effects of COVID-19 With POTS Cohort

Long Haul COVIDPostural Orthostatic Tachycardia Syndrome

The purpose of the study is three-fold. The primary aim is to identify the proportion of Long-Haul COVID (LHC) and non-LHC volunteers with relevant symptoms actually have postural orthostatic tachycardia syndrome (POTS). The second is to determine benefit of ivabradine treatment. Ivabradine is a drug approved to treat tachycardia in persons with heart failure. The third is to characterize risk factors and outcomes among volunteers with and without LHC. This will include comparison with COVID-19-positive individuals who did not develop long-COVID symptoms. The study will improve basic and applied knowledge of LHC and its associated cardiovascular and autonomic consequences. Cellular and molecular characterization of LHC and non-LHC participants will be performed with a nested clinical trial for Ivabradine responsiveness on reduction of tachycardia. It is hoped that a greater understanding of LHC, and related autonomic dysfunction in particular will help to identify treatment paradigms and therapeutic targets for improving recovery and enhancing health for those affected.

Radiosurgery for the Treatment of Refractory Ventricular Extrasystoles and Tachycardias

Ventricular Tachycardia

Patients with refractory ventricular extrasystoles or tachycardia not eligible for catheter ablation will receive single fraction stereotactic body radiation therapy (cardiac radiosurgery) with 25 Gy. Investigators initiated this study to demonstrate that in at least 70% of the patients the planned cardiac radiosurgery may be performed without any interruption or treatment related interventional events within the first 30 days after treatment.

Stereotactic Arrhythmia Radioablation for Ventricular Tachycardia Management

Stereotactic Radioablation for Ventricular Tachycardia

Stereotactic Arrhythmia Radioablation (STAR) ablation is a safe and feasible option for cardiomyopathy patients for management of refractory ventricular tachycardia. STAR can be performed with available cardiac imaging, prior mapping/electrogram information, and standard ECGs without a multi-electrode ECG vest.

Ablation at Virtual-hEart pRedicted Targets for VT

Ventricular TachycardiaIschemic Cardiomyopathy

The goal of this study is to test the efficacy of the new imaging/simulation ("virtual heart") approach for determining the optimal ablation sites in patients with VT, which render post-infarction VT non-inducible. The study will test both the acute outcome of the ablation procedure, and the effect the use of the predicted targets has upon procedure time.

Comparison of Landiolol Versus Standard of Care for Prevention of Mortality in Patients Hospitalized...

Septic ShockTachycardia2 more

Several data emphasize the relation between tachycardia (>90/min) and high mortality during septic shock. The investigators previously demonstrated the high mortality associated with hypercontractility, tachycardia and the presence of a left ventricular obstruction. A severe hypovolemia, a hyper adrenergic stimulation or a severe vasoplegia can all explain this relation between tachycardia, hypercontractility and the mortality during septic shock. Landiolol is another short-term acting beta-blocker with a half-life of 4 minutes without any beta 2 activity or membrane stabilizing effect. The landiolol has been used in critically ill patients to control supraventricular tachycardia but not in this context of tachycardia and septic shock. The investigators hypothesize that landiolol by reducing the heart rate may improve the survival of patients treated for a septic shock and presenting with an hypercontractility state.

TachycardiaDyspnea1 more

Most patients with acute COVID-19 (Coronavirus 19) recover within weeks, however a significant number of individuals will develop the post-acute COVID 19 syndrome (PASC). As of July 2021, the post COVID syndrome qualifies as a disability under the Americans with Disabilities Act. The symptoms which comprise this condition are highly variable and often extraordinarily debilitating. They may be distinct from the initial presentation or may mimic those which defined the initial infection. The post COVID syndrome can be diagnosed when symptoms persist longer than 3 months and may extend to beyond one year. There are risks for permanent levels of disability. Patients who seemingly did not have active COVID-19 symptoms in the days following infectious exposure may also develop post Covid syndromes. These syndromes are considered to constitute a distinct clinical entity which has of yet no clearly defined pathogenic mechanism or validated treatment algorithms. International investigative efforts are now underway to determine who might develop the post COVID syndrome, it's long term consequences and how best to treat its many problematic symptoms.

HEAL-IST IDE Trial

Inappropriate Sinus Tachycardia

Inappropriate Sinus Tachycardia (IST) is a prevalent and debilitating condition in otherwise healthy younger patients, resulting in significant loss of quality of life, lacking effective treatment options or systematic clinical evidence to support a therapy. The primary objective of this clinical trial is to evaluate the safety and effectiveness of a hybrid sinus node sparing ablation procedure for the treatment of symptomatic drug refractory or drug intolerant IST.
