Several risk factors for PPCM have been individuated over the years, including Afro-American ethnicity, preeclampsia, advanced maternal age, genetic predisposition, multiparity, twin pregnancy, obesity, smoking and diabetes. However, PPCM pathophysiology is still poorly understood, thus making it challenging to develop disease specific therapies. At present, Bromocriptine is the only targeted drug, but further evidence is needed to establish indication and timing of administration. Therefore, these patients are mainly treated following general heart failure guidelines. Even though in most patients left ventricular ejection fraction recovers during follow-up, cases of persistent left ventricular dysfunction are not uncommon. Moreover, all patients detain a certain risk of recurrence after subsequent pregnancies, which is difficult to estimate due to the dearth of long-term prospective data.</p><p>In this manuscript, we aim to provide an updated review of current evidence about PPCM pathophysiology, diagnosis, treatment and recurrence risk.

It can be associated with congenital heart disease (CHD) with the following subtypes: 1) uncorrected left-to-right (L-R) intracardiac shunt leading to overload of the pulmonary circulation and a progressive increase of PVR; 2) Eisenmenger syndrome, appearing when a large post-tricuspid shunt is left uncorrected and pulmonary vascular disease (PVD) is severe, so the shunt becomes bidirectional or right-to-left, causing cyanosis; 3) PAH after shunt closure, when PVR arises after a defect correction; and 4) PAH associated with small or coincidental defects. While the treatment of patients with Eisenmenger syndrome is well established, the treatment of patients with PAH in whom there is a L-R shunt (with no cyanosis) remains unclear and requires expertise. In such patients, correction of the defect may be contemplated if there is mild PVD and a significant L-R shunt. Others may benefit from a “treat and repair” strategy, which involves the use of PAH therapy to achieve a drop in PVR, with the aim of achieving operability criteria. Cardiac catheterization is at the center of the evaluation and follow-up of these patients, collecting “baseline” data and providing the opportunity to challenge the pulmonary circulation, manipulate the loading status, or temporarily occlude the defect. This article provides a detailed overview of the pathophysiology and treatment options for patients with PAH associated with a L-R congenital shunt, including current approaches to operability and the use of PAH therapies.</p></div>","PeriodicalId":73429,"journal":{"name":"International journal of cardiology.

PH is classified into five subgroups, of which Group 1 pulmonary arterial hypertension (PAH), is the most extensively studied. Numerous causal genes have been identified in PAH, most notably germline mutations in bone morphogenetic protein receptor type 2 (<em>BMPR2</em>) and the wider BMP pathway. Often when considering the genetics of PH, sporadic idiopathic and heritable PAH dominates the discussion. There are a number of reviews that elegantly describe the ‘state of the art’ in respect to group 1 PAH, however this focus misses the wider context of genetic conditions where PH is a feature, but outside of the framework of classical ‘idiopathic or heritable’ PAH. In addition to variants in genes within the TGF-β/BMP signaling pathway, genes which regulate ion channels, the extracellular matrix, inflammation, angiogenesis, and mitochondrial dysfunction have been shown to play a significant role in PH pathogenesis across different PH groups. In this review, we aim to cast the net wider to understand what we can learn from the spectrum of genetic conditions where PH is an acknowledged feature or complication, and what this tells us about the important cellular, molecular and systems physiology features that predispose to PH and consequently might be treatment targets.</p></div>","PeriodicalId":73429,"journal":{"name":"International journal of cardiology.
