Derliz Mereles kommt aus Asunción, Paraguay, und ist seit 1993 wissenschaftlicher Mitarbeiter, seit 2009 Leiter des Echolabors der kardiologischen Abteilung der Medizinischen Klinik der Universität Heidelberg.

Sein Medizinstudium absolvierte er in Paraguay. Er erlangt 1987 den Titel "Doctor en Medicina y Cirugía" der Universidad Nacional de Asunción, und 2004 den Titel "Doctoris medicinae" der Ruprecht-Karls-Universität Heidelberg. 1999 wurde ihm der Titel Facharzt für Kardiologie von der Paraguayischen Ärztekammer verliehen.

Seine langjährige Erfahrung in der Echokardiographie möchte er mit dieser Anleitung weitergeben.
