Heart valve surgery

Based on a patient's surgical risk, diagnostic testing, individual evaluation and disease, our structural heart team may recommend surgical treatment.

The experienced cardiothoracic surgeons in our cardiology department provide treatment to diseased heart valves through surgical intervention. Heart valves may either be repaired or replaced, depending on the extent of the disease.

In certain situations, the surgeon can restore the valve to function normally by remodeling the tissue, removing stretched tissue or sewing the edges. In some cases, prosthetic or artificial rings may be used to narrow a dilated valve and to reinforce the integrity of the valve.

Heart valves that are seriously degenerated or diseased cannot be repaired. In these cases, the old valve is removed and replaced with a new valve mechanism. The new valve is attached by sewing it to a rim of tissue kept from the original valve. There are different types of valve mechanisms in two categories: tissue valves and mechanical valves.

  • Surgical mitral valve repair or replacement (MVR)
  • Surgical tricuspid valve repair or replacement (TVR)
  • Transcatheter aortic valve replacement (TAVR)
  • Transcatheter ASD and PFO closure
  • Transcatheter closure of left atrial appendage
  • Transcatheter mitral valve repair (TMVR)
  • Transcatheter repair
  • Transcatheter valve-in-valve therapy

Aortic stenosis treatment

Aortic stenosis occurs when the aorta, the main artery pumping blood from the heart, narrows or stops opening fully. In its early stages, patients experience a decrease in blood flow, chest pain, weakness or fainting.

Left untreated, aortic stenosis can lead to further complications and even death. We perform a range of procedures to treat aortic stenosis, including TAVR.

What is a TAVR procedure?

TAVR is a procedure performed by a specially trained TAVR specialist who replaces a diseased aortic heart valve without open-heart surgery. This alternative to surgery involves a balloon-expandable heart valve, which is placed into the heart through a catheter. A catheter is a small tube, which goes into an artery through a small incision. (In the case of TAVR, the incision is in the thigh.)

Our TAVR operating room is equipped with technology, which allows our TAVR team great precision.

Transcatheter mitral valve repair (TMVR)

TMVR is a cutting edge alternative to open-heart valve surgery. It is often recommended to patients with mitral regurgitation who are considered to be high risk for conventional valve repair or replacement surgery. TMVR is a minimally invasive, catheter-based procedure that is often used to treat patients who have previously undergone mitral valve replacement surgery.


LAAO is an alternative to long-term blood thinner therapy for stroke risk reduction in patients with non-valvular atrial fibrillation. In this catheter-based procedure, a surgeon uses imaging technology to place the LAAO device.

ASD/PFO closure

Until recently, there was no safe and effective catheter-based method of ASD or PFO closure. Problematic ASDs and PFOs required open-heart surgery. Today, Northside Hospital is proud to offer a wide variety of catheter-based occlusion devices to close these holes safely.

Cardiac rehab

We offer inpatient and outpatient cardiac rehabilitation programs to promote a full and speedy recovery following heart surgery. Cardiac rehab involves education and a range of therapies tailored to each patient's condition to increase stamina and improve heart health.
