Consultant Heart and Lung Transplant Physician in the Mater Hospital


Dr O¿Connell works full time as one of only 2 full time consultants nationally with a full time commitment to the medical management of Heart and Lung Transplant patients.


The Irish Heart and Lung Transplant Centre currently performs the 3rd highest number of transplants per head of population in Europe and has some of the best reported post-transplant survival rates internationally with a 5 yr post lung transplant survival rates of over 75% in lung transplant patients. In 2015, the program performed over 50 solid organ transplants, between heart and lung transplant patients, including the first ever combined heart and lung transplant in Ireland. It also performed the first case of an ex-vivo lung perfusion reconditioned lung, which was successfully transplanted into a young patient with Cystic Fibrosis.


The Transplant group in the Mater runs an internationally renowned research program, with international presentations across medical, surgical and microbiological fields, and currently our microbiologist is the President of the European Society of Heart and Lung Transplant society.

Research Interests

I have been accepted as one of the National collaborators in a Cochrane review for Compliance strategies in Transplant patients.


I am currently the first author on the largest endobronchial ultrasound study in the world (over 1500 patients), evaluating a novel formula for stratifying the risk of malignant mediastinal lymph node involved by EBUS in non small cell lung cancer, in collaboration with Prof David Ost, MD Anderson, Texas, Prof Lonny Yarmus, Johns Hopkins, Baltimore, Dr Franceisca Almeida, Cleveland Clinic, Cleveland and Prof Michael Simoff, Henry Ford Hospital, Detroit. This paper has currently been submitted to Lancet Respiratory Medicine.


Other interests and projects include:

1.                   Ex-vivo lung perfusion studies: improving organ donor utilisation rates using a novel ultrasonic nebulizer to aid reconditioning of explanted lungs

2.                   Cystic Fibrosis Original research: National collaborative project on the Lung-Gut microbiome post-transplant in patients with CF

3.                   Developing National Heart and Lung Transplant Guidelines: 140 page document nearing completion of which I am the first author.

4.                   Cancer incidence in Heart and Lung Transplant patients in Ireland- collaborative project with Dr Fergal Mallone

UCD Medicine Research Centre: Rare Diseases



Recent Postgraduates

1.Currently supervising UCD MD Thesis student Dr Andre Pozza


2. Funding for a second MD student starting July 2016 for Dr Jana Kleinerova sourced



Teaching Philosophy

I believe in consultant led teaching for under and post graduate medical students, with an emphasis on developing problem solving skills and on developing empathetic doctors who understand their role not just as leaders but also who demonstrate empathy and understanding with their patients.

Innovation & Leadership

I am the primary Investigator and have submitted local ethics approval for a novel interventional bronchoscopy technique (electrospray by Profector) to study endobronchial airway tumours.
