Welcome to Our Practice

Cardiovascular Associates (CVA) is a top surgical group located in the Rio Grande Valley in South Texas. CVA was founded by the late Marion R. Lawler, MD., the first to perform open heart surgery in this region. Currently it is compromised by Ruben M. Lopez, MD, FACS, a native to the area. He specializes in the acute care in cardiac, thoracic, vascular, endovascular, pediatric, general, and trauma surgery.

Dr. Ruben M. Lopez performs operations on the heart and blood vessels of the body. There are many different types of operations on the heart, and may include replacement of heart valves, or bypasses of blocked coronary arteries. This type of operation is either performed with the heart lung machine (on pump) or without the heart lung machine, (OPCAB or OFF Pump). He also performs advanced work on the aorta utilizing endovascular technology. This type of surgery allows the patients to go home within 24 hours. Because of his advanced training in General Surgery and Trauma Surgery he is also able to perform a wide variety of other surgeries in the pediatric and adult population.
