Interventional Cardiology & Electrophysiology

The interventional cardiology and electrophysiology unit of Clinique Pasteur has a dedicated catheterization laboratory, with an adjoining cardiac intensive care unit (CICU). Procedures are performed percutaneously, through a simple arterial or venous puncture, with no incision and no open-heart surgery. It treats diseases of the heart arteries (coronary angiography, angioplasty with stent placement), valve diseases (percutaneous valvuloplasty) and the full range of heart rhythm disorders: electrophysiological studies, ablations, pacemaker and defibrillator implantation. A team of experienced interventional cardiologists and electrophysiologists ensures coordinated care alongside cardiac testing, cardiac surgery and intensive care.

Services & Examinations

Diagnostic coronary angiography

The reference invasive examination for visualizing the coronary arteries by injecting a contrast agent, used to locate and quantify coronary narrowings (stenoses).

20 to 45 minutes for the procedure; allow half a day to a full day of hospitalization

Right and left heart catheterization

Invasive hemodynamic exploration of the right and left heart chambers by catheterization, measuring intracardiac pressures and blood flow to assess overall cardiac function.

45 minutes to 1h30 depending on the extent of the exploration; hospitalization for 24 to 48 hours

Coronary angioplasty with stent placement

Percutaneous procedure to widen a coronary artery narrowed by atherosclerosis and place a stent (a small metal mesh tube) to keep the artery open.

45 minutes to 2 hours depending on complexity; hospitalization for 24 to 72 hours

Percutaneous valvuloplasty

Percutaneous dilation of a narrowed (stenotic) heart valve using a balloon inflated across the valve, avoiding the need for open-heart surgery.

1 to 2 hours for the procedure; hospitalization for 2 to 4 days

Intracardiac electrophysiology study

The reference examination for analysing the heart's electrical circuit from the inside and precisely identifying the origin of a rhythm disorder.

1 to 2 hours

Radiofrequency ablation of arrhythmias

Curative treatment of heart rhythm disorders that neutralises, with a radiofrequency current, the area of the heart responsible for the arrhythmia.

2 to 4 hours depending on the type of arrhythmia

Atrial fibrillation ablation

Interventional treatment of atrial fibrillation by pulmonary vein isolation, to restore a regular heart rhythm.

2 to 4 hours

Atrial flutter ablation

The reference treatment for atrial flutter, an organised rhythm disorder of the atrium, with excellent lasting results.

1 to 2 hours

Ventricular tachycardia ablation

Specialised interventional treatment of rhythm disorders arising in the ventricles, guided by three-dimensional mapping.

3 to 5 hours

Pacemaker implantation

Placement of a cardiac pacemaker that constantly watches over the heart rhythm and stimulates it whenever it beats too slowly.

About 1 hour

Implantable cardioverter-defibrillator (ICD) implantation

Placement of an implantable defibrillator that continuously monitors the heart and automatically protects it against serious rhythm disorders.

1 to 2 hours

Cardiac resynchronisation therapy (CRT)

Implantation of a specific pacemaker that re-coordinates the heart's contractions to improve the symptoms of heart failure.

1 hour 30 minutes to 3 hours

Holter ECG and blood pressure monitoring

Continuous recording of the heart rhythm or blood pressure over 24 to 48 hours, in the patient's real-life conditions.

Fitting in a few minutes, recording over 24 to 48 hours

Exercise stress test

Treadmill exercise test under continuous medical supervision, to assess the heart's behaviour during exercise.

30 to 45 minutes in total, including 10 to 15 minutes of exertion
