    Dr. Lazala attended The Autonomic University of Santo Domingo, and then continued his training at The Technologic University of Santiago where he earned his medical degree in 1988. He held various positions within the Health System of the Dominican Republic, including Medical Director of Maimon Sub Health Center in Banao as well as Medical Sub Director of the San Ramon Clinic in Banao, Dominican Republic. 

    One of Dr. Lazala’s contributions to the Department of Cardiothoracic Surgery is the creation of a Hemodynamics Lab within the cardiac cluster of operating suites where surgical staff performs vital tests on the blood otherwise done by the lab, typically located in another area of the hospital.  Having the ability to perform tests such as thromboelastography, PT INR, as well as platelet counts, steps away from the patient alleviates the need to send blood for testing down to the hospitals’ lab during cardiac procedures.  This lab is beneficial to the patient as surgical time is decreased and these vital results are garnered much quicker.
    Dr. Lazala is a member of the Coagulation and Hemostasis in Cardiac Surgery Research Team where the group investigates the hemostatic defects commonly present in the cardiac surgical population due to cardiopulmonary bypass and the perioperative use of antiplatelet and anticoagulant agents. 

    Dr. Lazala received his Assistant Professor appointment in 2010.

Coagulation and Hemostasis in Cardiac Surgery

This group investigates the hemostatic defects commonly present in the cardiac surgical population due to cardiopulmonary bypass and the perioperative use of antiplatelet and anticoagulant agents. Ongoing projects continue to characterize the hemostatic defects and focus on improving hemostatic competence in the perioperative period. An additional focus is the implementation and validation of point-of-care devices for research and clinical applications.
