A cardiothoracic surgeon at USA Health recently performed a surgical procedure to seal off the left atrial appendage in a patient’s heart with a clip — the first such procedure in the area to be performed robotically. The milestone marks a new option for patients across the Gulf Coast region whose irregular heart rhythms could not previously be addressed through minimally invasive means, and it extends the range of robot-assisted surgery available close to home.
The surgeon, Parker Mullen, M.D., said the precision of robot-assisted surgery using the da Vinci Xi enabled him and his team at USA Health Providence Hospital to address the patient’s atrial fibrillation, an irregular heart rhythm disorder that could not be treated with more traditional methods because of the patient’s health history.
“This patient presented a real challenge for other minimally invasive options given their prior heart surgery. Performing this procedure robotically allowed us to operate with an exceptional level of precision while minimizing the impact on the patient,” said Mullen, who also serves as an assistant professor of surgery at the Frederick P. Whiddon College of Medicine at the University of South Alabama.
How the Procedure Works
The left atrial appendage is a small, ear-shaped pouch in the upper left chamber of the heart, and it is where blood clots tend to form in patients with atrial fibrillation. Clots that escape the appendage can travel to the brain and cause strokes, which is why sealing the appendage off from the heart’s circulation has become an important strategy for stroke-risk reduction in patients who cannot tolerate long-term blood-thinning medication or whose rhythm disorder persists despite other treatment. Closing the appendage with a clip, rather than sewing it closed or managing risk with medication alone, gives surgeons a permanent, mechanical solution.
In the operating room, a surgeon controls the da Vinci Xi robot’s four tiny instruments from a console using magnified views of the surgery site. The system translates the surgeon’s hand movements into precise motions at the instrument tips, filtering tremor and allowing work in spaces that would otherwise demand a large open incision. The benefits of robotic surgery include a shortened hospital stay, less blood loss, reduced complications and less post-operative pain — advantages that matter most for cardiac patients, whose recovery from traditional open-chest approaches can stretch for months.
For this patient, the robotic approach was not merely a preference but the determining factor. Scar tissue from prior heart surgery typically makes repeat operations dramatically riskier and often rules out minimally invasive alternatives, leaving patients with difficult choices between open surgery and unaddressed risk. The robotic platform’s ability to navigate that anatomy with magnified, three-dimensional visualization is what made the case feasible.
USA Health, which has six da Vinci Xi robots and one da Vinci SP robot, launched its robotic thoracic surgery program in December 2025. The investment in multiple platforms across the health system reflects a broader institutional commitment to robotic approaches, with the fleet serving surgical teams across specialties rather than sitting dedicated to a single service line.
“Our goal is to be the academic referral center for the region for thoracic procedures,” Mullen said. The ambition positions USA Health to draw complex chest and cardiac cases from across south Alabama, the Mississippi Gulf Coast and the Florida panhandle — patients who have historically traveled to larger cities for advanced robotic procedures. As an academic health system anchored by the Whiddon College of Medicine, USA Health pairs its clinical programs with teaching and research missions, meaning procedures like this first-of-its-kind robotic appendage closure also train the next generation of surgeons who will practice along the Gulf Coast.
A Growing Robotic Program
The da Vinci robots have also been used in abdominal hernia, esophageal, gastrointestinal, colonic, hiatal hernia, cancer, urologic and gynecologic surgeries across the health system. That breadth is the point of a multi-robot fleet: a single platform that urologists, gynecologists, general surgeons and thoracic specialists all train on creates institutional depth, shared expertise among operating room teams and redundancy that keeps schedules running when systems need maintenance. Patients benefit from surgeons who perform high volumes of robotic cases across the system, and referring physicians gain a local destination for procedures that once meant long drives.
Atrial fibrillation itself is one of the most common heart rhythm disorders in the United States, and its prevalence climbs with age, making it a significant concern along the Gulf Coast, where retiree populations are substantial. The condition causes the heart’s upper chambers to beat irregularly, which allows blood to pool and clot — particularly in the left atrial appendage. Management options have traditionally included medications to control rhythm and rate, anticoagulants to reduce stroke risk, catheter-based ablation and surgical approaches. For patients whose anatomy or surgical history rules out several of those paths, a robotic clip closure adds a genuinely new alternative.
Providence Hospital’s role in the milestone is also notable. The campus has long served west Mobile and the surrounding communities, and hosting the region’s first robotic appendage closure there extends the reach of USA Health’s academic medical capabilities beyond its downtown footprint. For patients in outlying counties, the difference between a procedure available locally and one requiring travel to New Orleans, Birmingham or Pensacola can determine whether they pursue treatment at all.
The December 2025 launch of the robotic thoracic program means the milestone arrived within the program’s first months, an early proof point for the investment. Health systems typically build referral volume for new surgical programs over years, and a first-in-the-area procedure performed safely gives referring cardiologists and primary care physicians a concrete reason to route complex cases to USA Health.
Robotic surgery’s expansion across the Gulf Coast mirrors a national trend, but the region’s geography makes local access especially valuable. South Alabama’s population is spread across Mobile, Baldwin and the surrounding rural counties, and cardiac patients in particular benefit from short travel distances when complications arise after discharge. A health system that can offer robotic thoracic and cardiac procedures locally keeps follow-up care, emergency backup and rehabilitation within reach of the patient’s home community.
The da Vinci Xi platform’s four instruments work through small incisions, and its console gives the operating surgeon a magnified, high-definition view of the surgical field — capabilities that have made robotic approaches standard for an expanding list of procedures since the technology’s adoption accelerated nationwide. The addition of the da Vinci SP, a single-port system, extends robotic options to procedures where multiple incision sites are impractical, further widening the range of cases the health system can handle minimally invasively.
For patients evaluating surgical options, the practical questions are familiar: how long will recovery take, how much pain should be expected, and what are the risks? Robotic procedures consistently answer those questions favorably compared with open surgery — shorter stays, less blood loss, fewer complications and reduced post-operative pain — though the technology remains a tool guided entirely by the surgeon at the console. Training and case volume matter enormously, which is why the academic structure at USA Health, where Mullen teaches surgical residents through the Whiddon College of Medicine, strengthens the program’s foundation.
The first-in-the-area robotic left atrial appendage closure signals to cardiologists across the region that cases previously considered too complex for minimally invasive treatment now have a local option. As the program matures, officials expect the mix of robotic procedures to broaden, building on a platform that has already proven itself across hernia repairs, gastrointestinal surgery, oncologic resections, urology and gynecology throughout the health system.
For the patient involved, the procedure’s significance comes down to options that did not exist locally before. Patients with prior heart surgery and persistent atrial fibrillation have historically faced a narrow menu: manage risk with medication for life, travel out of the region for specialized procedures, or accept the elevated risks of a repeat open operation. A robotic clip closure performed close to home changes that calculus, and it is exactly the kind of case academic health systems cite when explaining why they invest in robotic platforms and the surgical leadership to use them.
Stroke prevention sits at the center of atrial fibrillation care, and appendage closure has grown rapidly as a strategy nationwide as evidence has accumulated on its effectiveness for appropriate patients. Sealing the appendage removes the chamber where most atrial fibrillation-related clots form, addressing stroke risk at its source. Doing so robotically, through small incisions rather than a sternotomy, compounds the benefit for patients whose recovery capacity is already limited by age or prior operations.
The milestone also lands at a moment of growth for USA Health more broadly, as the academic system has expanded clinical services across Mobile and Baldwin counties in recent years. Each first-of-its-kind procedure performed locally raises the ceiling on what patients can expect from their own health system, and each one trains surgical teams whose experience compounds across future cases.
Mullen’s dual role — practicing cardiothoracic surgeon and assistant professor at the Whiddon College of Medicine — embodies the academic model the program is built on. Residents and fellows who observe and participate in procedures like this one carry the technique into their own practices, multiplying the reach of a single case. That teaching mission, paired with the region’s first robotic appendage closure, gives USA Health a story it expects to build on as the referral center for thoracic procedures across the central Gulf Coast.
