About

I am a cardiologist with a practice covering general and interventional cardiology.

I manage everything from simple evaluations to the most complex situations, with expertise in coronary artery disease.

Trained in Switzerland and abroad, I served for several years as a senior hospital physician before developing an independent practice in collaboration with various centers, combining clinical follow-up with access to specialized technical facilities.

My practice relies on modern assessment and decision-making tools: functional tests, advanced cardiac imaging, and invasive techniques including intracoronary imaging and physiology.

When indicated, I also perform treatments for structural pathologies, including the closure of intracardiac shunts, treatment of aortic valve disease, and left atrial appendage closure.

My approach aims for diagnostic precision, appropriate indications, and intervention only when necessary. I place particular importance on clear explanations and a relationship of trust with my patients.
