Minimally Invasive Heart Procedures

Cox-Maze IV - Surgical ablation of atrial fibrillation
Atrial fibrillation (AFib) is the most common cardiac arrhythmia, is a major cause of stroke, and is increasing in prevalence. Treatment options include anticoagulant medications and catheter-based or surgical procedures. Surgical treatments for AFib have improved greatly over the past two decades. Boulder Heart's heart surgeons offer extensive experience in the current the gold standard for surgical AFib treatment: the Cox-Maze IV procedure. Involving only small incisions and punctures, Cox-Maze IV combines bipolar radiofrequency with cryoablation.

Hybrid ablation - Addressing difficult-to-treat AFib
BCH's heart surgeons are one of only handful of surgeons in the state to perform hybrid ablation, an advanced, minimally invasive procedure to treat atrial fibrillation. Hybrid ablation is a collaborative procedure performed by both a heart surgeon and an electrophysiologist in which the heart surgeon creates scar tissue on the outside of the heart while the electrophysiologist does the same on the inside by using a catheter-led device to freeze malfunctioning tissue. The resulting “helpful” scar tissue blocks damaged electrical pathways that cause AFib's characteristic irregular heartbeat. Patients experience only three small incisions in the chest and small punctures in the groin, and can return home after just one or two nights in the hospital.

Thoracic endovascular aortic repair (TEVAR) - Repairing aortic aneurysms
TEVAR repairs the aorta using a stent-graft, a flexible metal coil that seals off the weak part of the aorta and protects it from growing any larger. Since TEVAR only requires small groin incisions, it typically leads to shorter hospital stays and quicker recovery times compared to traditional surgical approaches.
