Dr. Giovanni and his staff made me feel at ease during a very difficult time. They always answer all my questions, do not rush me through appointments, are available for all my questions at all times. I still have more surgeries ahead of me, but I’m not nervous or scared because I have all the confidence in the world in Dr. Giovanni. I could not be happier with Dr. Giovanni and his staff.

Interventional  Cardiology

John Giovanni Cardiac Center’s physicians maintain complex interventional skills for the non-surgical treatment of heart disease. We offer diverse treatment options to correct narrowed, blocked arteries, including:

Structural Heart Disease

   WATCHMAN the WATCHMAN is implanted into the Left Atrial Appendage (LAA) in a one-time procedure. It is designed to permanently close off the LAA and keep blood clots from escaping. WATCHMAN is about the size of a quarter and made from very light and compact material commonly used in many other medical implants. Visit https://www.watchman.com/en-us/home.html to learn more.

TAVR (Transcatheter Atrial Valve Repair) is a option for patients with severe aortic valve stenosis that are not surgical candidates. This procedure is performed through a catheter which is used to deploy a device to replace the aortic valve. Open heart surgery is not required with this procedure.

Mitraclip is a minimally invasive procedure that may be an option for patients with degenerative mitral regurgitation who are too sick for surgery. MitraClip therapy is the only transcatheter mitral valve repair (TMVR) option to treat mitral regurgitation.  

Paravalvular Leak ClosureMost often, the Doctor will insert a catheter in the femoral vein in the groin (leg). A wire is guided through the catheter to the upper left chamber of the heart, using a technique to go through the septum (muscular wall that divides the upper chambers of the heart into the right and left sides). A special catheter is used to place a closure device around the leak which acts like a plug to stop the leak.  

Peripheral Vascular Disease

Balloon Angioplasty – also known as Percutaneous Transluminal Coronary Angioplasty (PTCA), this non-surgical procedure follows an angiogram that indicates a blocked artery and/or narrowing in the artery due to fatty deposits. The procedure involves insertion of a special catheter with a tiny balloon on the end into a narrow heart artery. When the catheter reaches the blocked area, the balloon is inflated to flatten the fatty deposits against the artery wall. When successful, this permits a bigger opening inside the artery and blood flow improves.

Peripheral Angioplasty – a balloon angioplasty as described above, however, the procedure is performed on a vessel outside of the heart, for example the leg vessels.

Stent Placement – this is a small metal coil or slotted tube that is placed within a heart artery following an angiogram, which indicates a blockage and / or narrowing of the artery due to fatty deposits. The stent is designed to help support the arterial wall and push aside and fatty deposits. A catheter with a balloon is used to place a stent into an artery. When the balloon is inflated inside of the stent, the stent expands. The stent supports the arterial wall and aids in holding the artery open. The stent is a permanent implant that will remain in the artery.


Our sub specialists focus on the electrical mechanics of the heart. Abnormal heart rhythms may require mechanical assistance or an interventional procedure to correct the abnormal function, including:

Implantable Cardioverter Defibrillator (ICD) – This electrical device continuously monitors your heartbeat and is implanted inside the body, usually under the skin in the upper chest just below the collarbone. It if senses a dangerous rapid heart rhythm, it delivers one or more pulses or shocks to the heart and restores a normal heart rhythm. An ICD may be a treatment following a cardiac arrest or a rapid heart rhythm problem that could lead to a cardiac arrest. Because it is a life-saving aid, having an ICD may give you more freedom to participate in activities you enjoy.

Implantable Pacemaker – The pacemaker is an electronic device that monitors the heart’s electrical activity and delivers electrical pulses, as the heart needs them. If it senses that the heart is beating too slowly or pauses for too long, the pacemaker stimulates the heart with precisely timed electrical pulses. The pacemaker is implanted into the body, usually under the skin in the upper chest just below the collarbone.

Catheter Ablation – This is a non-surgical technique, which eliminates parts of the heart’s abnormal electrical pathway, which is causing a rapid heart rhythm. During this treatment, an electrode catheter is inserted into the heart. The catheter is positioned so that is lies close to the abnormal electrical pathway and then radiofrequency energy passes through the catheter. The tip of the catheter heats up in order to eliminate small areas of heart tissue that contains the abnormal electrical pathway. If successful, radio-frequency ablation may cure the problem of a rapid heart rhythm.

Heart Failure Program

Patients in our Heart Failure Program receive comprehensive, outpatient treatment for their heart failure by cardiologists and a nurse practitioner who specialize in heart failure management. Heart failure is a chronic condition in which symptoms are potentially recurrent and disabling. Aggressive outpatient care, including optimal medical management along with intensive patient education and monitoring, improves outcomes in this cardiac condition.

Our Heart Failure Program was started in 2007 and has resulted in a decrease of over 78% in repeat hospitalizations among the patients in our program.

The goals of the heart failure program include:

•Optimize and individualize medical therapy.

•Educate patients and families to provide better understanding and management of heart failure. Our intensive patient education includes understanding the disease process, medication, symptom monitoring, diet and activities.

•Increase patient and family participation in the management of the patient’s heart failure.

•Minimize symptoms, maximize quality of life and slow the progression of heart failure.

•Decrease emergency department visits and hospital admissions.

Coumadin Management

Patients on anti-coagulation therapy receive frequent laboratory tests and visits with our registered nurse to ensure that proper blood coagulation levels are maintained. Our nurse will teach you about factors that may affect your blood coagulation and work with your cardiologist to adjust your medication when necessary.

Our special feature is that within a 30-minute visit, you’ll have a protime/INR blood test, test results, a visit with our nurse to verify your daily anti-coagulation therapy doses and your next appointment.

Pacemaker/Implantable Cardiac Defibrillator Management

Just like other heart conditions that require close management, pacemakers and implantable cardiac defibrillators are no exception. Both devices are routinely checked to verify the sensing and pacing functions, verify program settings and the battery life.

Enhanced External Counter Pulsation (EECP)

A therapy available for patients experiencing angina, or angina symptoms, such as chest pain, chest discomfort, etc. This therapy is a non-invasive, non-prescription therapy that involves seven weeks of treatment. The therapy relieves angina symptoms by helping to develop collateral circulation and increases stamina, exercise tolerance and quality of life for 75 to 80% of patients.
