Cardiothoracic Surgery

With a broad range of advanced treatment options and a team of experienced surgeons, turn to Hahnemann University Hospital’s cardiothoracic surgery program for your surgical cardiac care.

One of the most common cardiac procedures is coronary artery bypass surgery. Our surgeons use the latest techniques including all arterial revascularization bypass, minimally invasive approaches and hybrid procedures. In arterial revascularization, blocked arteries are bypassed using arteries taken from a patient’s own chest or arm, rather than veins. This restores normal blood flow to the heart, lowers the risk of future heart problems and enables patients to resume a normal lifestyle. 

Cardiothoracic Surgery Offerings

Coronary revascularization bypass procedures at Hahnemann selectively may be performed off pump, meaning the patient is not put on a heart-lung machine during the operation. Instead, surgeons use special devices to stabilize the beating heart, thus allowing for natural blood flow. This technique can potentially reduce kidney and lung complications in certain cases.

Our surgeons also specialize in minimally invasive procedures, or keyhole surgery, using advanced technology –– to repair or replace faulty heart valves using mechanical or natural valves as well as perform coronary artery bypass.  These procedures performed through small incisions can potentially give improved cosmetic results, less discomfort, and rapid recuperation.  In hybrid coronary revascularization, cardiac surgeons work hand in hand as a team with cardiologists to stent some arteries and bypass others to minimize the risk and improve outcomes in select cases.

For patients with atrial fibrillation – one type of common abnormality of the electrical system of the heart – our surgeons are experienced in several procedures including the Maze procedure and left atrial exclusion. Performed alone or in conjunction with another cardiac procedure, the Maze procedure surgically treats arterial fibrillation by interrupting the abnormal electrical patterns.

New treatments for patients with atrial fibrillation include atrial appendage occlusion. This provides a cover over part of the upper chamber of the heart that tends to collect blood clots in patients with atrial fibrillation. In many patients who are candidates, this can help the patient avoid a lifetime of blood thinner medications. Other treatments include the WATCHMAN device and the Impella cardiac assist device. Some of these procedures are performed in Hahnemann’s cath lab

Mechanical support for patients with cardiogenic shock using various techniques and devices is a specialty of our program.  Additionally, we have experience with many heart and lung support techniques including Extracorporeal Membrane Oxygenation (ECMO).

Other areas of expertise include:

  • Minimally invasive direct coronary artery bypass (MIDCAB)
  • Minimally invasive surgery for closure of atrial septal defects
  • Transmyocardial laser revascularization (TMR) for severe angina patients whose arteries are not suitable for bypass (considered ungraftable)
  • Ventricular remodeling operations as an alternative to heart transplant in some patients with end stage heart failure (the DOR procedure)
  • Repair of traumatic injuries to the heart and blood vessels
