Biomodeling the human anatomy in exact structure and size is an exciting field of medical science. Utilizing medical data from various medical imaging topography, the data of an anatomical structure can be extracted and converted into a three-dimensional virtual biomodel; thereafter a physical biomodel can be generated utilizing rapid prototyping machines. Here, we have reviewed the utilization of this technology and have provided some guidelines to develop biomodels of cardiac structures. Cardiac biomodels provide insights for cardiothoracic surgeons, cardiologists, and patients alike...

BACKGROUND: Deep hypothermic circulatory arrest (DHCA) is used to overcome the threat of cerebral ischemia during complex surgical operations of the heart and the aortic arch. Remote ischemic preconditioning (RIPC) has been shown to mitigate neurological damage. METHODS: We analyzed blood samples in a consecutive series of 52 piglets that underwent a 60-min period of DHCA with RIPC (the RIPC group) or without (the control group), to reveal whether the protective effect to oxidative stress could be seen by measuring serum 8-hydroxydeoxyguanosine (8-OHdG)...

Congenital left ventricular diverticulum is a rare cardiac anomaly. During the newborn period, symptomatic patients are diagnosed with heart failure findings. We present a 23-day-old male newborn with congenital left ventricular diverticulum diagnosed during fetal echocardiographic examination. After the birth, the patient had heart failure symptoms and his echocardiographic examination showed low cardiac ejection fraction. Diverticulum was operated with endoventricular circular patch plasty (DOR) technique, and after, cardiopulmonary bypass venoarterial extracorporeal membrane oxygenation (ECMO) support was performed because of low cardiac output syndrome...

A 10-day-old boy was transferred to our hospital due to tachypnea. Patent ductus arteriosus (PDA), 4.8 mm in diameter, with small ASD was diagnosed on echocardiography. Surgical ligation of the ductus was performed after failure of three cycles of ibuprofen. However, the ductus remained open on routine postoperative echocardiography on the second postoperative day, and chest CT revealed inadvertent ligation of the left pulmonary artery (LPA) rather than the PDA. Emergent operation successfully reopened the clipped LPA and ligated the ductus on the same (second postoperative) day...

Three-dimensional (3D) printing involves preparing 3D objects from a digital model. These models can be used to plan and practice surgery. We used 3D printing to plan for a rare complicated surgery involving the removal of a renal tumor and neoplastic mass, which reached the heart atrium. A printed kidney model was an essential element of communication for physicians with different specializations.

BACKGROUND: Deficiency of vitamin D is known to be effective in the development of hypertension, coronary artery disease, myocardial infarction, and stroke. Deficiency of vitamin D was also shown to be associated with new onset atrial fibrillation (AF) by activating the renin-angiotensin system. This study investigated whether or not levels of vitamin D are effective in the development of AF after coronary artery bypass grafting (CABG) surgery. METHODS: A total of 283 patients undergoing CABG were included in this study...

Thrombocytopenia occurring after surgical bioprosthetic valve implantation is a phenomenon that has been long investigated, and various explanations have been provided [Santarpino 2012a]. Our group has been addressing this topic over several years, extending back to the original description of this phenomenon in Freedom Solo (Sorin Group, Saluggia, Italy). However, we observed that this was a transitory and self-limited phenomenon without clinical consequence [Santarpino 2011; Santarpino 2012a]. Our center began implanting the Perceval aortic valve (Sorin Group, Saluggia, Italy) in 2010, and we have gained a vast experience in sutureless aortic valve replacement with Perceval, with more than 300 implants performed to date [Fischlein 2015]...

BACKGROUND: The noninvasive evaluation of right ventricular function (RVF) in cardiovascular and pulmonary diseases remains a challenge. Internationally recommended echocardiographic parameters for the evaluation of RVF may not be applicable to China, because of the limited examination time per patient, the varying skill levels of ultrasonographers, inadequate allocation of professional specialties, and outdated instruments and equipment. METHODS: Sixty-two patients admitted for right heart failure and 52 healthy volunteers were included in the analysis...

In an era of rapid, cheap, and efficient electronic communication, the practice-and art-of letter writing has faded. There are many reasons for us as physicians and surgeons to resist this evolution. And, there are many opportunities to employ letter writing to the benefit of ourselves, our patients, and our colleagues. A true Doctor of Humane Letters is an honorary degree, generally awarded for significant contributions to society.  However, given that humane can be defined as showing compassion, understanding, mercy, and tolerance, we can all strive to be worthy of such a distinction...

Left ventricular noncompaction cardiomyopathy (LVNC) is a rare hereditary cardiomyopathy characterized by the formation of an outer compacted and inner noncompacted layer of the myocardium. The latter is characterized by prominent trabeculations and deep intertrabecular recesses and is functionally inferior to the compacted myocardium. As there is no specific treatment for patients with LVNC who develop heart failure, the management of these patients is limited and many patients progress to advanced stages of the disease...
